Error installing latest CentOS kernel from %post section of kickstart
by Alfred von Campe 01 Sep '11

01 Sep '11

I'm running the command "yum -y update" from a script called from the the post section of my kickstart config file, and I get the following error: Installing : kernel-2.6.32-71.29.1.el6.i686 185/378 grubby fatal error: unable to find a suitable template After the install, if I log in to the system and remove that RPM and then re-install it with "yum install kernel", the grub.conf file is updated correctly. Any ideas why this might be failing from kickstart? Anyone else seen this? Alfred

Help integrating CentOS 6 with existing network login infrastructure
by Alfred von Campe 01 Sep '11

01 Sep '11

I've updated my kickstart configuration files to work with CentOS 6 and am most of the way there integrating a CentOS 6 system into our LDAP/NIS environment. My authconfig line in the kickstart file is as follows: authconfig --enablemd5 --passalgo=sha512 --enablenis --nisdomain=XXX --nisserver=nis.XXX.com --useshadow --enablekrb5 --krb5realm=XXX.COM --krb5kdc=ldap.XXX.com --krb5adminserver=ldap.XXX.com This is virtually identical to the authconfig line I was using in CentOS 5. My issue is that users cannot log in with their network (NIS) usernames and passwords. If I log in as root, I can do a "su - username" and get the user's automounted home directory with the correct uid/gid, but if I try to log in as the user, or do a "su - username" as a non-root user and have to enter the password, authentication always fails. The entries in /var/log/secure just say "su: pam_unix(su-l:auth): authentication failure". I'm not a pam expert and don't know how to debug this. Anyone else run into this and/or know what might be the problem? This works just fine in CentOS 5. Alfred

Question re: CentOS-6.0, KVM, and /dev/sr0
by James B. Byrne 31 Aug '11

31 Aug '11

I am experimenting with KVM and I wish to create a virtual machine image in a logical volume. I can create the new lv without problem but when I go to format its file system then I get these warnings: Warning: WARNING: the kernel failed to re-read the partition table on /dev/sda (Device or resource busy).

(Centos 5.6) Server Time NTP Facility
by Always Learning 31 Aug '11

31 Aug '11

Curiously examining some of the blocked IP addresses in the daily Logwatch report, I notice strange sites attempting to connect to our servers on port 123 (the time port). I also notice our servers successfully contacting official time references centres which are not those sites trying to connect to us. I notice too the installed time software is listening on every available IP. I can not identity any options in any configuration files to turn-off this listening. Why are unknown sites attempting to connect to our server to, I assume, sample the time and how does one turn-off the software's listening on every IP address, including 127.0.0.1 ? Thanks, Paul.

xendomains not starting at boot
by Theo Band 31 Aug '11

31 Aug '11

On one of my xen hosts a virtual machine does not start at boot. I can see that xendomains gives an error: service xendomains start Starting auto Xen domains: fszeleNo handlers could be found for logger "xend" Error: Disk isn't accessible No handlers could be found for logger "xend" Error: Disk isn't accessible An error occured while creating domain fszele: Usage: xm create <ConfigFile> [options] [vars] Create a domain based on <ConfigFile>. Options: -h, --help Print this help. --help_config Print the available configuration variables (vars) for the configuration script. -q, --quiet Quiet. --path=PATH Search path for configuration scripts. The value of PATH is a colon-separated directory list. -f=FILE, --defconfig=FILE Use the given Python configuration script.The configuration script is loaded after arguments have been processed. Each command-line option sets a configuration variable named after its long option name, and these variables are placed in the environment of the script before it is loaded. Variables for options that may be repeated have list values. Other variables can be set using VAR=VAL on the command line. After the script is loaded, option values that were not set on the command line are replaced by the values set in the script. -F=FILE, --config=FILE Domain configuration to use (SXP). SXP is the underlying configuration format used by Xen. SXP configurations can be hand-written or generated from Python configuration scripts, using the -n (dryrun) option to print the configuration. -n, --dryrun Dry run - prints the resulting configuration in SXP but does not create the domain. -p, --paused Leave the domain paused after it is created. -c, --console_autoconnect Connect to the console after the domain is created. ! [failed] [FAILED] The actual command executed turns out to be: XMC=`xm create --quiet --defconfig $dom` where dom=/etc/xen/auto/fszele If I issue the command from the command line, the dom starts as expected. After some debugging on /etc/init.d/xendomains it turns out to work if I change this line: diff xendomains* 283c283 < XMC=$(xm create --quiet --defconfig $dom) --- > XMC=`xm create --quiet --defconfig $dom` or diff xendomains* 283c283 < XMC=`echo debug;xm create --quiet --defconfig $dom` --- > XMC=`xm create --quiet --defconfig $dom` So I fixed the problem using $() instead of back-ticks, but I like to understand what can be the root cause of this problem.

Apache warns Web server admins of DoS attack tool
by m.roth＠5-cent.us 31 Aug '11

31 Aug '11

Anyone have any idea how soon RHEL and CentOS will be releasing the patch package? Excerpt: Computerworld - Developers of the Apache open-source project today warned users of the popular Web server software that a denial-of-service (DoS) tool is circulating that exploits a bug in the program. The tool, called "Apache Killer," showed up last Friday in a post to the "Full Disclosure" security mailing list. Today, the Apache project acknowledged the vulnerability that the attack tool exploits, and said it would release a fix for Apache 2.0 and 2.2 in the next 48 hours. --- end excerpt --- <http://www.computerworld.com/s/article/9219471/Apache_warns_Web_server_admi…> mark

selinux & iptables
by Michael D. Berger 30 Aug '11

30 Aug '11

In setting up my new CentOS 6 laptop, I replaced /etc/sysconfig/iptables with my own, very restrictive version. I then tried to restart the iptables daemon, but it reported that my new iptables was unreadable. On a guess, I disabled selinux, and my problem was solved. Later, I re-enabled selinux and on reboot, it had to go through a very long setup procedure. Is there something better I could have done when replacing iptables, so that I would not have to disable selinux? Thanks for your help. Mike.

6.0 Media problems
by ken 30 Aug '11

30 Aug '11

When I downloaded the iso for 6.0 install, K3b said the iso wouldn't fit on the blank DVD. So I downloaded and burned the LiveDVD. When I boot it, I get the blue splash screen (it says "CentOS... Community Enterprise OS on the bottom, logo to the right), but nothing else comes up. Hitting various keys does nothing. Downloaded and burned the Netinstall CD. It gives an error message that it can't install because the machine's CPU doesn't have pae. So is it the end of CentOS/RH for this machine? (I can't believe that. One of the great things about Linux has always been that it'll run on old hardware.) Or are these fixable problems? Or are there workarounds? Or should I go for a different distribution? -- War is a failure of the imagination. --William Blake

resize2fs
by Ed Morrison 30 Aug '11

30 Aug '11

Hi All: I am trying to resize a centos (5.2) VM drive. I use VMware and I have increased the size of the drive by 40G. I am running resize2fs on /dev/sdb1 (which is my root partition) but when I do I get this error: [root@centos ~]# resize2fs /dev/sdb1 120G resize2fs 1.39 (29-May-2006) The containing partition (or device) is only 19970795 (4k) blocks. You requested a new size of 31457280 blocks. How can I change the block size? I have also tried to use gparted live cd but it will not allow me to increase the size even though it sees 40g of unused space. I can only create a new partition. Any help would be appreciated. Thanks, Ed

Installing 6.0 via USB
by Kenneth Porter 30 Aug '11

30 Aug '11

I'm using LiveUSB-Creator to create a bootable USB drive from CentOS-6.0-i386-netinstall.iso, and it gives me an error at startup: vesamenu.c32: Not a COM32R image I can hit tab and select "linux" and then it loads vmlinux and the initrd, says "Ready", and then just hangs. I'm not sure what's supposed to happen next. "vesa" and "rescue" do the same thing. The error message above apparently is caused by the syslinux in the ISO not matching the one that LiveUSB-Creator installs to boot from: <https://bugzilla.redhat.com/show_bug.cgi?id=662557> The system has 512 MB of memory. Is that enough to boot the installer?

Postfix not set top start after upgrade

I noticed that after the lastest yum update on CentOS 5.6 we get Postfix 2.3.3, but the status of the postfix service (chkconfig --list postfix) changes to off. So after a reboot, it doesn't start automatically. I don't recall this ever happening before. Is this by design? A packaging error? Thanks, Micha

CentOS 6 IPv6: neighbor and restart network
by Helmut Drodofsky 30 Aug '11

30 Aug '11

Hallo, for using the ipv6 neighbor functions, I have to execute commands like ip -6 neigh add proxy 2001::211:d8ff:fe97:3273 dev eth0 to publish the ip of computers in the subnet. To execute them on reboot, I have included these commands in /etc/rc.d/rc.local Also after each restart of the network, I have to execute these commands too. So: how can I always execute /etc/rc.d/rc.local after service network restart My idea: Is it possible to rename /etc/network to /etc/network_original and to create a new shell script /etc/network to execute both? Other/better advice? Thank you for help in advance. Helmut

mail.centos.org : packets to strange ports

ImageMagick : Centos GUI ?
by Always Learning 30 Aug '11

30 Aug '11

I accidentally discovered 'convert'. It is a command line utility. Changing a file from png to gif works like this convert aaa.png aaa.gif Amazingly simple, powerful and effective. I've since discovered it has an amazing list of options convert --help a manual file:///usr/share/doc/ImageMagick-6.2.8/www/convert.html and a web site http://www.imagemagick.org/ Does anyone have suggestions for a GUI which works for Centos 5.6 ? In production I run the command line program from PHP with 'exec'. Thank you, Paul. Currently automatically, rotating when necessary, downsizing photographs to 900 pixels wide (the software calculates the height) and labelling them with the file reference and photograph date - all in one quick operation. Mind boggling options, more than I've ever seen in similar software. Really amazed :-)

Off topic list for centos please?
by Keith Roberts 30 Aug '11

30 Aug '11

Could we have a centos-offtopic list please, so anything that would be considered OT can be posted there? That way it would keep anything considered as OT and list-noise off the main centos specific list. So each users then has the option of being on the main centos list, and/or the centos-offtopic list as well. That would keep the more experienced centos users happy, and allow us less experienced centos users to also learn from each other as well. I for one like to learn from such posts as the [CentOS] OT: Hardware upgrade help, as 64 bit is something I'm interested in learning about from other centos users that wish to contribute to threads like these. I think the centos-offtopic list should also be centos related, but not so strict postings as the current list is.

heartbeat

29 Aug '11

Is anyone else running heartbeat on CentOS 6 on x86_64? We have it installed, rpm -qi says it's from fedora, and /etc/init.d/heartbeat, after sourcing its shell environment, decides that it should look for the executables in /usr/lib/heartbeat. Unfortunately, where I found them, and where the package installed them, is in /usr/lib64/heartbeat. I haven't d/l the RH rpm, since I see that's in fedora, so I'm *assuming* they're they same. I just want to check, before I file a bug with upstream. mark

Hello there! I've recently switched from Fedora 11 to CentOS6. Now my SD cards (automatically mounted on plug) contents is displayed as UPPERCASE filenames.

I'd like to change the defaults for devices that automatically mount in GNOME.. is this possible? In gconf-editor, I don't see a storage/ subdir in system/.. Any hint? Regards, -- wwp

mounting an ext3 filesystem "-o ro"
by Philippe Naudin 29 Aug '11

29 Aug '11

Hi, I want to do something *bad* : to mount an already mounted ext3 partition. Mounting "-o bind" is not an option, this partition is mounted by different virtual machines. NFS is the right way to go, so I want another one :-) I have no problem mounting this partition read-only, but it seems that actually it is not really read-only. From /var/log/messages : Aug 29 11:26:43 xen02 kernel: EXT3-fs: INFO: recovery required on readonly filesystem. Aug 29 11:26:43 xen02 kernel: EXT3-fs: write access will be enabled during recovery.

Aug 29 11:26:43 xen02 kernel: EXT3-fs: mounted filesystem with ordered data mode. This recovery is probably triggered by the file /.autofsck, but I have not found how to get rid of this feature. Is there a way to read an ext3 filesystem, completely disabling recovery and any write operation ? Thanks, -- Philippe Naudin

CentOS 6.0
by Thomas Dukes 29 Aug '11

29 Aug '11

Hello, Can anyone pls tell me if a ThinkServer TS130 with a E3-1225 Xeon processor is compatible with CentOS 6.0? I would like to upgrade from 5.6 but my hardware will not allow me to do so. I do not wish to buy something that is incompatible as I already have that now. The TS130 is replacing the TS200v which is RHEL 6.x certified. The TS130 has an Intel mobo and uses the C206 chipset. I do not know the model number for the mobo itself. I have spent the last 45 minutes on the phone with Lenovo and talked with 'Peggy' seven different times before being disconnected. TIA, Eddie

mysql authentication in proftpd
by Tim Dunphy 27 Aug '11

27 Aug '11

Hello list, I was able to get passive mode worked out. I'm really glad I was able to do this. I'm able to log into the ftp server, list directories, enter subdirectories and upload/download files. However my next task is to enable virtual users using mysql. I have installed proftpd-mysql and enabled the sql modules in the config. I found a good article on how to do this here: http://www.khoosys.net/single.htm?ipg=848 I set everything up according to this article, and authentication with the test user I have stored in the user table is failing. [root@LCENT05:~] #/usr/bin/ftp -d mydomain.net Connected to snjh.net (xx.xx.xx.xx). 220 FTP Server ready. Name (snjh.net:root): jfuser ---> USER jfuser 331 Password required for jfuser Password: ---> PASS XXXX 530 Login incorrect. Login failed. ---> SYST 215 UNIX Type: L8 Remote system type is UNIX.

I setup a debug log session and this is what I've found: 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching PRE_CMD command 'USER jfuser' to mod_tls 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching PRE_CMD command 'USER jfuser' to mod_core 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching PRE_CMD command 'USER jfuser' to mod_core 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching PRE_CMD command 'USER jfuser' to mod_delay 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching PRE_CMD command 'USER jfuser' to mod_auth 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching CMD command 'USER jfuser' to mod_auth 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching POST_CMD command 'USER jfuser' to mod_sql 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching POST_CMD command 'USER jfuser' to mod_delay 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching LOG_CMD command 'USER jfuser' to mod_sql 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching LOG_CMD command 'USER jfuser' to mod_log 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching PRE_CMD command 'PASS (hidden)' to mod_tls 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching PRE_CMD command 'PASS (hidden)' to mod_core 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching PRE_CMD command 'PASS (hidden)' to mod_core 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching PRE_CMD command 'PASS (hidden)' to mod_sql_passwd 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching PRE_CMD command 'PASS (hidden)' to mod_sql 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching PRE_CMD command 'PASS (hidden)' to mod_vroot 192.168.1.30 (189.15.88.64[189.15.88.64]) - mod_vroot/0.8.5: vroot registered 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching PRE_CMD command 'PASS (hidden)' to mod_delay 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching PRE_CMD command 'PASS (hidden)' to mod_auth 192.168.1.30 (189.15.88.64[189.15.88.64]) - dispatching CMD command 'PASS (hidden)' to mod_auth 192.168.1.30 (189.15.88.64[189.15.88.64]) - USER jfuser (Login failed): No such user found. It looks like authentication is bypassing mod_sql altogether and selecting mod_auth instead. The only authentication method I have enabled in the config is mod_sql so I'm not sure why this is occuring.

Cent OS 6 freezing up
by Jimmy Bradley 27 Aug '11

27 Aug '11

I've been out of pocket for a while, so don't shoot me, if this has already been brought up. I'm having a problem with my desktop freezing up, and I'm running Cent OS 6. It seems to happen while I'm running firefox. I'm not sure if it's firefox, or the OS that's locking up. When it freezes up, nothing will respond, so I'm inclined to think it's the OS that's freezing up. Has anyone else been having this problem? Thanks Jim

vmxnet3 patch for CentOS6 kernel?
by Matti Aarnio 26 Aug '11

26 Aug '11

Hi, Could CentOS kernel keepers apply following patch on current kernel? http://patchwork.ozlabs.org/patch/95785/ (Current as: 2.6.32-71.29.1.el6.x86_64) With the patch applied, and a ".local" kernel built, I get 30% higher throughput with vmxnet3 in my IP routing node, than when using e1000 "card" at the same. Without the patch, the TCP flow over vmxnet3 driver on a _router_ node is abysmally slow. I am running a bunch of CentOS servers on VMware ESXi 4.1U1 hosts with multiple of VLANs. The best network performance is obtainable with vmxnet3 network driver in normal case. This driver includes so called LRO optimization, which boosts TCP flow network performance on end-nodes, but kills it on routers, thus the LRO mode needs to be disabled on a host doing routing in between network interfaces. The issue is a bug in vmxnet3 driver, which is not able to disable LRO mode when the kernel is telling the driver to do so. The patch for it applies on 2.6.32 kernels as well as 2.6.38/39 where it got applied to baseline. Could this be applied on stock CentOS kernel so that I could return on un-customized kernel use? Best Regards, Matti Aarnio PS: bugs.centos.org is apparently unable to send email out, otherwise I would have written this as a bug report... <http://patchwork.ozlabs.org/patch/95785/>

Problems with kickstart installation into a Virtualbox
by anax 26 Aug '11

26 Aug '11

Hi listers i tried to kickstart-install CentOS 6.0 64 in a Virtualbox (Virtualbox Version 4.12). I used a local CDROM with the net-install ISO on it to boot from. The ISO distribution file was provided on a server in the LAN as was the kickstart file. When starting the installation i aded the following to the kernel line of the grub menu: ks=http://install.mydomain.com/ks/centos.6.64.cfg After i had corrected some errors in the kickstart file, the installation started as expected. But it did not terminate as expected: after installing 198 of 671 packages, the installation halted with an error (i.e. after installing the package libutempter). In order to see what the problem was, i restarted from the CDROM in recovery mode, and after going into the half-way installed system, i saw in the anaconda log that about three quarters of the post-installation scripts of the packages had returned a warning. The warning code was 255. But the post-installation script of the package libutempter had returned an error with code 255, whereupon the installation stopped. I thought, OK, we will work around the libutempter package by selecting other program-groups in the kickstart-file. But i had no luck: the installation stopped then after the package MAKEDEV. Then i left off kickstart-installation and did a standard installation booting from the CDROM and getting the default packages from the server in the LAN. This worked fine. ----- When it came to test the installed packages i was always lucky except with the package fuse (fuse-2.8.3-1.el6.x86_64) which contains the binary /usr/bin/fusermount. This binary was installed without execute permission for everybody, so it could be invoked only by the userid root and members of the group fuse, which is not, what i had expected. suomi

updating 5.6 but not going to 6.0
by Mike VanHorn 26 Aug '11

26 Aug '11

I'm confused as to how to install updates for CentOS 5.6 without upgrading to 6.0. When I do a "yum check-updates", the new *-release packages for 6.0 are listed, so I don't think I want to do a simply "yum update".

I'm having a problem with my desktop freezing up, and I'm running Cent OS 6. It seems to happen while I'm running firefox. I'm not sure if it's firefox, or the OS that's locking up. When it freezes up, nothing will respond, so I'm inclined to think it's the OS that's freezing up.

perl-Sys-Filesystem on 6.0
by m.roth＠5-cent.us 26 Aug '11

26 Aug '11

I'm trying to install a number of perl modules, and yum gives up with perl-Sys-Filesystem, because it has a dependency of perl(:MODULE_COMPAT_5.8.8) I've tried seeing what provides it, and yum says nothing. I also see, googling, that there was a problem thread on this list in '08 with the same dependency. Anyone have a clue, or workaround? mark

svnserve and SysVinit
by Andrew Dorozhkin 26 Aug '11

26 Aug '11

Hello there and SFME. Since el6 subversion package doesn't contain traditional SysV demonization script anymore I wonder how it is supposed to run svnserve from now on. 1) Should one write init script to be managed with service(8) on his own? 2) Or launch svnserve on demand via (x)inetd? 3) Or put svnserve command line in some rc-script? 4) Or maybe is ra_svn deployment scheme not supported in el6 at all and one should stick with Apache/mod_dav_svn? Thanks d.a.

Audacious crashing (64bit)

Hello there, My first post here and even my first CentOS (after years of Fedora). Audacious is crashing at startup, here's the output: audacious: relocation error: /usr/lib64/audacious/Input/ffaudio.so: symbol av_register_protocol2, version LIBAVFORMAT_52 not defined in file libavformat.so.52 with link time reference Does anybody reproduce? Would this reveal a problem (or my misuse) with rpmfusion ffmpeg packages?

UPS issues with PFC PSU
by Robert Arkiletian 25 Aug '11

25 Aug '11

Just noticed that our new server has a newer 80+ efficiency 865W PSU with PFC. So apparenty our existing 1500VA (865W) APC Back-UPS is not safe to use anymore. We apparently need a pure sine wave UPS. http://nam-en.apc.com/app/answers/detail/a_id/8883 I found an affordable 1500VA UPS by CyberPower, model CP1500PFCLCD, which has a pure sine wave output. Wondering if anyone has experience with CyberPower UPS's. Are they any good? Any problems with pwrstatd ? -- Robert Arkiletian Eric Hamber Secondary, Vancouver, Canada

OT: Hardware upgrade help
by Thomas Dukes 24 Aug '11

24 Aug '11

I would like to upgrade my system to a 64 bit machine. I'd like to find a bare bones platform to build on. I'm not looking to spend a lot of money on this as it is a home system. I looked on the CentOS sponsor page but only saw hosting services. I haven't kept up with hardware in years so I'm dumber than dirt on what's out there. I would prefer a desktop so I can stack it. Don't think I need to do the Xeon as that would be overkill for a home user. This would be replacing my 'server' so I need PCI slots for an additional NIC and a 32 bit video capture card used for zoneminder. Not sure what PCI express is or if my cards would work in those slots. Yep, I'm running 8 yrs old machines, IBM NetVistas. :-( Any help or referal to a sponsor would be greatly appreciated. TIA, Eddie

Hello Is anyone else having problems on 5.6 using the new rsync from the CR repo I have only managed to get rsync (called from the cli) working again after downgrading it to the previous 2.x release as the newer version was just spitting out the ssh usage information and failing.

Missing UIDs
by Anne Wilson 23 Aug '11

23 Aug '11

From time to time I'm seeing this message: I couldn't find the numerical IDs of these users: abrt nslcd pulse rtkit saslauth tcpdump usbmuxd In most cases this is caused by inconsistencies in the user or group database, e.g. between the files /etc/passwd, /etc/group and their respective shadow files /etc/shadow and /etc/gshadow. I will try to ignore these entries and continue for now, but please fix these inconsistencies as soon as possible.it </quote> My first thought was to use system-config-user and create users with IDs matching their group IDs. However, doing it that way requires passwords to be set. How should I correct this? Anne

qemu-kvm-0.15 + CentOS 5.6 + vanilla 2.6.35.14 (working, patch included)
by Walter Haidinger 23 Aug '11

23 Aug '11

Hi! Just in case somebody else needs this. Below is a patch which allows building qemu-kvm-0.15 unter CentOS 5.6 with vanilla kernel 2.6.35.14 and (optionally) vde2 [1]. FYI: qemu-kvm-0.15 compiles fine on CentOS 6 with distro-kernel, no patches needed. For CentOS 5.6, unpack 0.15 qemu-kvm tarball [2], apply the path below, configure and compile. Make sure to export the kernel include path before building, otherwise the kernel mman-common.h header won't be found: export CPATH=/lib/modules/2.6.35.14/build/include The patch also adds some #error pragmas to make sure that KSM is used. This isn't a requirement to run, though. If you'd like to use vde2 too, then additionally export the paths to the vde2 installation (here: /opt/vde2) before configure (if vde2 is not installed in /opt/vde2 then change your paths accordingly): export CCFLAGS="-I/opt/vde2/include" export LDFLAGS="-L/opt/vde2/lib" export LD_LIBRARY_PATH="/opt/vde2/lib${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}" With the above, ./configure --enable-vde works (for me). I'm posting this here, rather than on a kvm list, because this is rather CentOS 5 specific, IMHO. Anyways, if you reply to this, please be sure to add a CC: to my email address. While I am subscribed to this list, your email might get buried by the list traffic. Thanks.

cant login remotely proftpd
by Tim Dunphy 23 Aug '11

23 Aug '11

Hello list! Well I have delved back into my proftpd config in the hopes of resolving my issues and having a working server. :) I believe I have the passive mode issue that I was expereriencing last time mostly worked out. But there are still a couple of things going on with this config that I was hoping to run by you in hopes of finding a solution. If I execute an ftp session on localhost from the ftp server itself, I can log in and the ftp client does not complain when I try to list a directory. [root@VIRTCENT29:~] #/usr/bin/ftp localhost Connected to localhost (127.0.0.1). 220 FTP Server ready. Name (localhost:root): bluethundr 331 Password required for bluethundr Password: 230 User bluethundr logged in Remote system type is UNIX. Using binary mode to transfer files. ftp> ls 227 Entering Passive Mode (127,0,0,1,183,201). 150 Opening ASCII mode data connection for file list 226 Transfer complete ftp> quit 221 Goodbye. However if I log into the external address of the FTP server the login fails. Name (snjh.net:root): bluethundr 331 Password required for bluethundr Password: 530 Login incorrect. Login failed. Remote system type is UNIX. Using binary mode to transfer files. ftp> quit 221 Goodbye. There is no activity in the logs when I log in remotely. I dont believe it to be a firewall issue because iptables on the local ftp server has been disabled by stopping the service and the router has been configured to open port 21 and the passive ports I have selected (60000-65535). I have verified that port 21 is open with nmap: [root@VIRTCENT29:~] #nmap -p 21 snjh.net Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2011-08-22 20:39 EDT Interesting ports on pool-71-187-203-194.nwrknj.fios.verizon.net (71.187.203.194): PORT STATE SERVICE 21/tcp open ftp Nmap finished: 1 IP address (1 host up) scanned in 0.371 seconds And it looks like the system is prompting for a password, but authentication fails. But why it only fails when I attempt this remotely and it works when I do this locally is a bit puzzling. And if I mount an NFS directory login fails on localhost too: [root@VIRTCENT29:~] #mount nas2:/mnt/home /home [root@VIRTCENT29:~] #/usr/bin/ftp localhost Connected to localhost (127.0.0.1). 220 FTP Server ready.

Mount --bind source / mountpoint out of sync
by Trey Dockendorf 22 Aug '11

22 Aug '11

I have a shared web server that users can SSH / SFTP into to access their web content. Each users home directory is in a change root, and I use "mount -o bind" to put their respective webpage's document root into their home directory. Recently I was made aware that the contents of the mount's source are not the same as the mount point's, which I don't see how that is possible. The file system is 3 virtual disks...each part of the same volume group. I have three LVMs, "/" , "/chroot" , and "/var". Here's the entry in /etc/fstab... /var/www/example.com /chroot/home/user1/example.com none defaults,bind 0 0 The mount is active, yet running a recursive diff between "/var/www/ example.com" and "/chroot/home/user1/example.com" shows numerous differences. Here's "mount" output ------------------ /dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) /dev/sda1 on /boot type ext3 (rw) tmpfs on /dev/shm type tmpfs (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) /dev/mapper/VolGroup00-lv_chroot on /chroot type ext3 (rw) /var/www/example.com on /chroot/home/user1/example.com type none (rw,bind) /dev/mapper/VolGroup00-lv_var on /var type ext3 (rw) I honestly have no idea how this is possible. Is using "mount -o bind" not the best method to give a chrooted user access to a single directory outside the chroot? Would it be better to leave the web root in the chroot and have Apache (outside chroot) reference that location? Thanks - Trey

Does anyone know if I can reconfigure a PERC H700 without rebooting?
by Kevin Thorpe 22 Aug '11

22 Aug '11

Hi all, I have a server which is really difficult to restart because of usage requirements and the fact that it's in a co-lo rack so miles away. I've added a couple of drives which I'd like to bring up and add to LVM but the config I know is in the PERC BIOS and requires a reboot. Can the config be changed in the openmanage suite and if so can someone point me in the right direction? thanks

Determine high i/o reads/write directories
by Robert Arkiletian 22 Aug '11

22 Aug '11

I have a DRBL server, basically an nfs fileserver, which I am rebuilding. I want to put the high i/o directories on a separate raid array for performance. Currently everything is under / in one raid array. How can I tell which directories, obviously other than /home, are getting high reads and/or writes? Any tools to measure i/o per directory?

Apache Changing IPtables C 5.6 via Apache
by Always Learning 22 Aug '11

22 Aug '11

When a web site is attacked, so far by unsuccessful hackers, my error routine adds the attackers IP address, prefixed by 'deny', to that web site's .htaccess file. It works and the attacker, on second and subsequent attacks, gets a 403 error response. I want to extend the exclusion ability to every web site hosted on a server. My preferred method is iptables. However, when breaking-out of a PHP script on a web page and running a normal iptables command, for example: iptables -A 3temp -s 1.2.3.4 -j DROP iptables responds with: iptables v1.3.5: can't initialize iptables table `filter': Permission denied (you must be root) Executing 'whoami' confirms Apache is the user. Giving Apache group rw on the /etc/sysconfig/iptables and ensuring the /sbin/iptables is executable by all, fails to resolve the problem. Is there any method of running iptables from an Apache originated process ? Thank you. -- With best regards, Paul. England, EU.

Multipath w/ iscsi
by Joseph L. Casale 22 Aug '11

22 Aug '11

I have several CentOS 6 boxes that mount iscsi based luns and use mpath. They all had problems shutting down as a result of unused maps not getting flushed as the system halted. After examining the init scripts, netfs, iscsi and multipathd all had the correct order but mpath failed to flush these maps and the system waited indefinitely. In the meantime I hacked this by adding a `/sbin/multipath -F` at the end of the stop clause in the init script. I seriously doubt this problems exists w/o being the result of my error in configuration. Anyone know what the required mpath config might be in this scenario where the block devices all disappear once netfs unmounts and iscsi stops? Thanks! jlc

help with gpg
by Jerry Geis 21 Aug '11

21 Aug '11

Under Centos 5 I ran this command: gpg --passphrase-file /home/myuser/pass_phrase.txt -c ../Versions/program.x86_64.tgz and this worked fine. On CentOS 6 running the same command prompts me for the passphrase. Thats exactly what I dont want to have happen. I have the pass phrase I want in the file. After some searching it says I need to start the daemon like "gpg-agent --daemon" take the output: GPG_AGENT_INFO=/tmp/gpg-x4WH7K/S.gpg-agent:19156:1; export GPG_AGENT_INFO; and use it - which I did. Then when I run my command above I still get prompted for the pass phrase. What am I not doing correct? I just want a simple phrase on a file that someone has to know before they can extract it. Nothing special going on.... Thanks, Jerry

Centos6 - Logwatch not mailing on 64bit
by david 21 Aug '11

21 Aug '11

Folks Logwatch is doing its thing properly on my 32-bit servers, delivering the report by mail to my root account once a day sometime around 3:30am. On the 64-bit systems, no mail is occurring. From the "cron" log on a 64-bit system, there are lines like: cron-20110821:Aug 21 03:36:23 XXX run-parts(/etc/cron.daily)[9727]: finished 0logwatch (where "XXX" stands for the server name) but no report is sent. If I run logtwatch manually, by simply typing logwatch as root, I get the mail. Is this a known issue? Is there some information I could supply that would help identify the reason? To the best of my knowledge, I made no changes to the logwatch configuration. Thanks David Kurn

Fedora and CentOS no longer on speaking terms
by Anne Wilson 20 Aug '11

20 Aug '11

I have just upgraded my server from CentOS 5 to CentOS 6 and am having connectivity problems. My laptop runs Fedora 14, and I have been in the habit of mounting data partitions on my server by fstab entries. Since the update I've not been able to do that. On watching the messages during a reboot I saw a statement that the connection was denied by the server (where are those messages stored so that I can quote accurately?). I have temporarily disabled both the firewall and selinux, and the problem persists, so clearly they are not the cause. Logwatch has the following section which may or may not be connected: --------------------- Connections (secure-log) Begin ------------------------ Userhelper executed applications: anne -> system-config-users as root: 1 Time(s) **Unmatched Entries** polkitd(authority=local): Operator of unix- session:/org/freedesktop/ConsoleKit/Session2 successfully authenticated as unix-user:root to gain TEMPORARY authorization for action org.fedoraproject.config.firewall.auth for system-bus-name::1.88 [/usr/bin/python /usr/bin/system-config-firewall] (owned by unix-user:anne): 1 Time(s) polkitd(authority=local): Registered Authentication Agent for session /org/freedesktop/ConsoleKit/Session1 (system bus name :1.24 [/usr/libexec/polkit-gnome-authentication-agent-1], object path /org/gnome/PolicyKit1/AuthenticationAgent, locale en_US.UTF-8): 1 Time(s) polkitd(authority=local): Registered Authentication Agent for session /org/freedesktop/ConsoleKit/Session2 (system bus name :1.45 [/usr/libexec/polkit-gnome-authentication-agent-1], object path /org/gnome/PolicyKit1/AuthenticationAgent, locale en_GB.utf8): 1 Time(s) polkitd(authority=local): Unregistered Authentication Agent for session /org/freedesktop/ConsoleKit/Session1 (system bus name :1.24, object path /org/gnome/PolicyKit1/AuthenticationAgent, locale en_US.UTF-8) (disconnected from bus): 1 Time(s) polkitd(authority=local): Unregistered Authentication Agent for session /org/freedesktop/ConsoleKit/Session6 (system bus name :1.214, object path /org/gnome/PolicyKit1/AuthenticationAgent, locale en_GB.utf8) (disconnected from bus): 1 Time(s) ---------------------- Connections (secure-log) End ------------------------- An example fstab line is /Data1 /nfs4exports/Data1 none bind 0 0 Under CentOS 5 this was mounted by the exports line: /nfs4exports/Data1 192.168.0.0/24(rw,insecure,no_subtree_check,nohide) Following advice, I have changed this to: /Data1/ 192.168.0.0/255.255.255.0 *(rw,sync,insecure,no_all_squash) That hasn't helped at all. I'm completely at a loss, and really need to get this connection working again. I've done lots of googling and reading, but just feel to be digging an ever-deeper hole. All help appreciated. Anne

PHP 5.3: IUS vs CentOS repos
by Kenneth Porter 20 Aug '11

20 Aug '11

I need to upgrade PHP because the latest WordPress requires one at least at 5.2.4. What are the tradeoffs of using the php53 packages provided by CentOS versus IUS? I've seen that installing the RHEL-derived php53 requires removing php first and it creates package conflicts because it doesn't provide a virtual php-common package. That suggests I should install the IUS package. Is there any reason to avoid IUS and stay with the CentOS package? <http://www.bytebot.net/blog/archives/2011/07/24/updating-php-in-rhelcentos-…>

which firewall to automatically block bandwidth abusers?
by Rudi Ahlers 19 Aug '11

19 Aug '11

Hi, I'm looking for a firewall (preferably on Linux / UNIX) that could automatically block bandwidth abusers as soon as a connection goes over a certain speed, or limit - i.e. either more than say 3Mb/s or 10GB in a giving period (like weekly / monthly). But, I need it to block the IP to, or where the traffic comes from, or goes to. i.e. a user logs into a web server and upload a LOT of data, then the firewall should block him, but not other people. Or, someone uploads a small bit of data but downloads a lot of data and then get's blocked. But I need to set thresholds And I should be able to exclude certain IP's / domains from the limits. Does this make sense? Can this be done with iptables? If so, how? If not, what else could I use for this? A normal DDOS prevention firewall doesn't really work since it only blocks traffic coming in. But I need to limit traffic going out as well. The servers behind the firewall will serve mail, http, ftp, sql and SSH -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

Change bash colours like in VIM
by Dotan Cohen 19 Aug '11

In VIM one can easily change colours with ":set backgorund=dark". This doesn't actually change the background, but rather uses a colour scheme that is designed for a dark background. Is there any quick command like this for bash? I don't want to edit the whole config file if there is a quick way to get a better colour scheme.

Problem getting eth0 up
by Alfred von Campe 19 Aug '11

19 Aug '11

I'm just starting to test CentOS 6 in our environment, and as a first step did a basic install from DVD (Desktop target, all defaults). Next I will try to automate the installations as I did for CentOS 5 using the anakonda-ks.cfg file generated by the manual install. However, I can't wrap my brain around the new NetworkManager to get it to configure the eth0 interface to obtain an IP address from our DHCP server. I've seen the FAQ on the wiki and the interface is up, but it doesn't get an IP address. I've done the installation from DVD multiple times now, each time with the same result. What am i missing?

CentOS 6 and IPv6 neighbor proxy
by Helmut Drodofsky 18 Aug '11

18 Aug '11

To route a subnet in ipv6 there are two possibilities: - add route commands for the subnet in each computer - or use neighbor proxy in the router server I prefer neighbor proxy. So I have to activate neighbor proxy in the router: sysctl -w net.ipv6.conf.all.proxy_ndp=1 and I have to add entries for each client in the subnet like ip -6 neigh add proxy 2001:0:0:1:211:d8ff:fe97:3273 dev eth0 This works well but is lost on reboot. For the sysctl command there is /etc/sysctl.conf for permanent configuration. If I create a file route-eth0 in the directory /etc/sysconfig/network-scripts/ with the above ip neighbor command, the interface eth0 is immediately down. Restart of network brings: Bringing up interface eth0: Error: Unknown connection: 5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03. [FAILED] All Interfaces are NetworkManager controlled. Ask for help: - where can I store the command for a permanent configuration? - Shall I not further use NetworkManager? Thank you for help in advance Helmut

using posfix on the local LAN, with internet FQDN
by Rudi Ahlers 18 Aug '11

18 Aug '11

Hi all, I hope someone can help me with this please. One of our clients has an in-house Postfix mailserver which basically downloads mail for the individual users from our mail server hosted on the web using fetchmail. They use our SMTP server to send mail. Their email clients are then setup to get & send mail from the server, on 192.168.2.254 (for POP3 & SMTP). All mail between them on the local LAN gets send to each other via the server, and not the internet. This works quite well, but as soon as someone sends mail from the Linux server directly (it has webmin + usermin installed and has a basic webmail interface for when they're out of the office) it sends mail using the local machine name, instead of the domain name. for example, mail comes from esther(a)ser001.rewards.local. How do I tell Postfix to automaticlly send mail from <user>@<theirdomain.com> instead? Sorry for asking this, but I don't know Postfix very well and don't know what to call to, to search on google. -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

Centos Gotcha: YUM Groupinstall
by david 18 Aug '11

18 Aug '11

Folks I have encountered a situation with YUM that isn't what I expected. Let's suppose I want to install a group, call it G. My first question would be -- is the group already installed. Realize all of this is scripted. So, I use yum groupinfo and I see the list of installed groups, and those not yet installed. If group G is in the list of installed groups, one would think that there's no point in issuing a "groupinstall". But, to my surprise, a group can be listed as "installed", only to find that a groupinstall will actually do a lot of installs. So, I had to adapt my script to perform a "groupinfo G", parse the modules, and individually test them to see if they need installation. I do not understand this behavior -- group G is shown as "installed", but it really isn't. David Kurn

SAS storage arrays, C6, and SES lights
by John R Pierce 18 Aug '11

18 Aug '11

So I'm curious how SAS JBOD arrays and linux MDraid as implemented in CentOS6, and SES (SCSI/SAS Enclosure Services) backplane controllers 'get along' and how much configuration is needed to get the warning lights to work properly. scenario: whitebox server with a SAS backplane or two, daisy chained on a SAS HBA (like an LSI Logic 2008), and disks organized as several raid5/6 using linux mdraid. Does this system have to be configured to ensure that the activity and failure lights match the drive bays, or does the SAS/SES spec all sort that out 'plug and play' ? does mdraid properly set those warning lights automatically on a failed raid element? -- john r pierce N 37, W 122 santa cruz ca mid-left coast

RAID5 suddenly broken
by Mathieu Baudier 18 Aug '11

18 Aug '11

Hello, I have a RAID5 array on my CentOS 5.6 x86_64 workstation which "suddenly" failed to work (actually after the system could not resume from a suspend). I had recently issues after moving the workstation to another office, where one of the disks got accidently unplugged. But the RAID was working and it had reconstructed (as far as I can tell) the data. After I replugged the disk, it was working normally over the last two days (enough to get back to a proper state I guess/hoped) This RAID is used as an LVM volume group for all my important data, among them the root of the operating system(s). It based on four partitions on four separate disks (the third partition of each disk, 3 active, one spare) When booting, I get an error message similar to: raid5 failed: No md superblock detected on /dev/md0. and the LVM volume group does not come up. I then booted using the CentOS 5.6 LiveCD and tried to run a few mdadm command (see just below). It seems that there are some data still lying around, but I'm not very experienced with RAID and I thought that I would ask for advice before trying commands which may impact the data such as assemble, etc. Thanks in advance for any help! Mathieu [root@livecd ~]# mdadm --misc -E /dev/md0 mdadm: No md superblock detected on /dev/md0.

OpenLDAP setup and bootstraping in CentOS 6
by Mitch Patenaude 18 Aug '11

18 Aug '11

I'm having trouble getting openldap through its initial setup. I created a /etc/openldap/slap.conf file with a default rootdn and rootpw, and they didn't seem to take effect. After much wailing and gnashing of teeth I found that if there is a config directory at /etc/openldap/slapd.d, it will ignore slapd.conf. I can't figure out how to translate slapd.conf into the (new?) standard of slapd.d because all the examples I can find still use slapd.conf. Am I better off just deleting (or renaming) slapd.d? Does anybody know the proper format for slapd.d entries? Thanks, -- Mitch Patenaude

5.1.6 php to 5.3, a few questions
by Bob Hoffman 17 Aug '11

17 Aug '11

Alright, looks like I have to do this (centos 5.x install). Some questions.. 1) I imagine I have to uninstall my current version of php...will yum remove want to take a ton of programs with it? Would I have to individually uninstall each package instead? 2) yum down the new version from some repo and then install it. I imagine nothing from the previous setup will be there and I would have to start going through the program and config files to make it work with my system, yes? 3) for those that have done it, how many things broke when you took out the old and added the new? honestly just thinking about getting a new comp, installing centos6, adding some virtuals, moving the sites over to the new one and being done with it. Not comfortable with a version of php that will not be backported like 5.1.6 is with centos team. any problems you encountered, would love to hear about them. thanks

However, I can't wrap my brain around the new NetworkManager to get it to configure the eth0 interface to obtain an IP address from our DHCP server. I've seen the FAQ on the wiki and the interface is up, but it doesn't get an IP address. I've done the installation from DVD multiple times now, each time with the same result. What am i missing?

OT?
by Dave Stevens 16 Aug '11

I have a CentOS server with postfix running. A pop user's account was compromised and a lot of spam started being sent. My upstream ISP's mail program started refusing to talk to me because of the very high rate of mail, error 451. I disabled the compromised account. I then changed the postfix settings to deliver mail directly and flushed the mail queue. This resulted in spam being sent out. There were about 20K mails in the queue. I don't know how I might have handled this better, I would have preferred to not send the spam, but the volume was large and the labour of sorting out spam from legit email was prohibitive. Advice? A better list for this issue perhaps? Dave -- "It is no measure of health to be well adjusted to a profoundly sick society." Krishnamurti

Are file system mounts costly?
by Reynolds McClatchey 16 Aug '11

I recall a kernel parameter on Unix System V of number of mounted file systems. Max recommended was 8. Larger numbers slowed down inode location and impacted performance. Has Linux solved that bottleneck? Are 20 or 30 mounted efs and cifs file systems on one system OK? -- M Reynolds McClatchey Jr VP Engineering and Inventory Southern Aluminum Finishing Co Inc 404-355-1560 x222 Voice 1581 Huber St NW 404-350-0581 Fax Atlanta GA 30318
