Nagios installation problem
by Ben McGinnes 05 Nov '10

05 Nov '10

Hello, Has anyone managed a successful installation of Nagios using the RPMForge packages on CentOS 5.5? It looks like it should have worked, I followed the guides for Fedora and CentOS here (with appropriate path adjustments): http://nagios.sourceforge.net/docs/3_0/quickstart-fedora.html http://wiki.centos.org/HowTos/Nagios The SELinux policies look fine (I tend to ignore instructions to permanently disable SELinux, if I'm not using SELinux then there's no reason not to return to Slackware): # semodule -l | grep nagios nagios 1.1.0 # The nagios.cfg check gave the all clear: Reading configuration data... Read main config file okay... Processing object config file '/etc/nagios/objects/commands.cfg'... Processing object config file '/etc/nagios/objects/contacts.cfg'... Processing object config file '/etc/nagios/objects/timeperiods.cfg'... Processing object config file '/etc/nagios/objects/templates.cfg'...

Total Warnings: 0 Total Errors: 0 Things look okay - No serious problems were detected during the pre-flight check My adjustment of other config files is minimal, essentially just setting the email address to deliver notifications to. Yet every time I try to start the service I get this: # service nagios start nagios is stopped Configuration validation failed [FAILED] The error appears to be identical to that reported here: http://forums.meulie.net/viewtopic.php?f=61&t=6538&start=0 Like the original poster of the thread on that forum, I am able to start it with "nagios -d /etc/nagios/nagios.cfg" though various web pages continue to report an unspecified configuration error. Does anyone have any ideas? Regards, Ben

IP forwarding and OpenVPN
by Bart Schaefer 05 Nov '10

05 Nov '10

I have a CentOS 4 server that acts as a gateway for a small LAN. The lower half of the 192.168.144 address space is the LAN on eth1, the upper half is the WAN on eth0, and the default route is to 192.168.144.254 which is my DSL router; this has been working fine for years. However, it's recently become convenient to connect the server to a VPN from time to time, for which I've set up OpenVPN. This works for connections originating from the server itself, but breaks for machines on the LAN when accessing IPs in the ranges that are routed to the VPN. Connections to IPs not in the private network still work as before. Can anyone advise what I may need to change to configure the server to forward packets to the VPN? Pointers to documentation are welcome. Thanks. /etc/sysctl.conf has: net.ipv4.ip_forward = 1 net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.default.accept_source_route = 0

Folks, Thanks a *lot* to those who suggested I try fsck -cc - that took six hours, and at the end, I was standing there, and it tells me that there's two back blocks, one was /dead/base.pp, and... (wait for it) bad blocks, in node 1. I said yes, fix them, and rebooted, and I don't see complaints. mark "and there was much rejoicing"

failure to import ldif into ldap
by Tim Dunphy 04 Nov '10

04 Nov '10

Thanks all.. I have read the man of ldif.... your advice has gotten me quite far both in my current implementation and in my overall understanding of LDAP which I am hoping grows with each passing day. In my attempt to build my current directory, I have taken a dump of my last successful implementation (which was created on FreeBSD 8.1) and substituted values for the dc=company and dc=com values with the correct ones for the current directory (attempting to implement under CentOS 5.4) and even tho the correct schemas are in place it is choking on this entry: # defaults, sudoers, Services, acadaca.com dn: cn=defaults,ou=sudoers,ou=Services,dc=acadaca,dc=net objectClass: top objectClass: sudoRole cn: defaults description: Default sudoOption's go here And again I should have all the schemas in place to make this work... include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/inetorgperson.schema include /etc/openldap/schema/nis.schema include /etc/openldap/schema/misc.schema inlcude /etc/openldap/schema/sudoers.schema include /etc/openldap/schema/openldap.schema [root@ldap ldif]# ldapadd -h ldap -a -w secret -x -D "cn=Manager,dc=acadaca,dc=net" -f /home/tim/txt/ldif/acadaca-master.ldif adding new entry "cn=defaults,ou=sudoers,ou=Services,dc=acadaca,dc=net" ldapadd: Invalid syntax (21) additional info: objectClass: value #1 invalid per syntax Why this ldif will work in one directory but not another is a mystery at this point.. thanks again -- Here's my RSA Public key: gpg --keyserver pgp.mit.edu --recv-keys 5A4873A9 Share and enjoy!!

Copying root partition
by Timothy Murphy 04 Nov '10

04 Nov '10

I recently transferred the / partition on my CentOS server from a small disk to a large disk, using "rsync -auvz". This works fine, except that I get dozens of selinux warnings when I re-boot. I'm running selinux in permissive mode. Is there any way to make sure that all the files in a partition are kosher as far as selinux is concerned? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

Re: [CentOS] PATA Hard Drive woes

Probably not on the AC side, although the Back-UPS 650 isn't a full online UPS but a switching standby UPS (full online, like the APC Symmetra 16KVA units I have here) rectify to DC, float the batteries at all times, and run the output from inverter all of the time (unless they're switched to bypass). The SmartUPS 1400RM I had in front of the PC that suffered the glitchy power is, unless I'm mistaken, also a full online pure sinewave UPS like the Symmetra, and is still in service (I checked its output on my oscilloscope first, though). No, I was referring to the output DC voltages (+12V, +5V, +3.3V,-5V, and -12V) from the power supply inside the system. In addition to my own personal RAID1 of 250GB drives, I also, a different time, lost a RAID5 array of 15K 36GB SCSI drives in a Dell 1600SC server; testing the power supply showed lots of noise and complete dropouts of a few milliseconds duration on the drive connectors' 5V supply pins. Completely and thoroughly scrambled the servo data on the Hitachi drives. Meaning they didn't just start showing bad sectors; they started getting seek errors. The 5V line on the drive connectors was reading an AC RMS of 4V superimposed on the +5V, yielding an effective DC voltage of 4V. Happened over a period of three weeks, during which time I had a number of mysterious failures (the Hitachi drives were error-correcting so well that by the time they started reporting errors, it was way past too late, and it became impossible for the Hitachi drives to even power up). I found that the power supply in question, upon investigation, provided the motherboard (where the DC power sensors on that box are) with clean 5V, and the drives were powered from a separate 5V rail, meaning the Dell management system wasn't seeing the power problems. A simple power supply tester with a built-in meter can be bought for less than $20; a more thorough power analyzer will run more than that. But even the simple one caught the failing Dell 1600SC supply. It took an oscilloscope to test the Antec in my personal box; turned out it was a cold solder joint in the Antec. A new power supply is less expensive than the equivalent labor it took to fix the Antec. I keep a known good 500W ATX 12V server-grade (8 pin 12V plug with adapters, and 24-pin ATX plug with 20-pin adapter) around for testing; that's one of the very first things I check when a PC is brought in that is flaky. (The very first thing is the dust accumulation, and the second thing is the heatsink compound). One of the first things I do on any CentOS system I put together is install lm_sensors and gkrellm (gkrellm from a third-party repo). I then enable all the motherboard sensors that are available in the gkrellm plugins, and run it (either local GUI or through ssh X forwarding to my central monitoring PC). On supermicro boards I install SuperODoctor for Linux, available on the supermicro site. The GUI runs well (there are some odd dependencies, however) and will e-mail you on alarm conditions that you can set. These include fan RPM, temperatures, and voltages. The CLI program isn't quite so sophisticated, but it can be run periodically and the result sent by e-mail for health checks. Drives that are having trouble will show up with high iowaits; run iostat (from the sysstat package) and look at the await result. Long awaits mean the drive is having trouble (or it has firmware issues like WD's EARS and EADS drives have in RAID configurations).

I updated libX11 and the problem is solved. Maybe the updated firefox and xulrunner are not compatible with the older version.

Building Samba RPM packages for RHEL/CentOS 5 - Needed corrections to the .spec file
by Miguel Medalha 03 Nov '10

03 Nov '10

I just built from source the Samba 3.5.6 RPM packages for CentOS 5.x/RHEL5.x. I found some glitches in the included samba.spec file and I thought someone else might benefit from my recent experience. The spec file for RHEL/CentOS resides, on the sources tree, under "samba-3.5.6\packaging\RHEL\". 1 - The process initially fails due to a dependency problem: missing "keyutils-devel". Change the respective entry on line 31 (BuildRequires:) to "keyutils-libs-devel" (yum install this file from the repositories if needed). 2 - Although it is called by the packaging process, the "umount.cifs" file is not compiled and therefore cannot be found in sources3/bin at the moment of packaging. Therefore, the RPM build process fails. Either comment the references to the file from lines 237, 396 and 414, if you don't need this function, or add the following to the ./configure command, starting on line 137: --with-cifsumount The default for this parameter is "no", and therefore it is not included in the "configure" process as is. 3 - The RPM build process finally fails because some files, which were compiled and copied to the temporary tree, are not called by the packaging process. The following lines must be included on the spec file, under "Files section": /usr/share/locale/de/LC_MESSAGES/net.mo %{_includedir}/wbc_async.h %{_mandir}/man5/pam_winbind.conf.5.gz I suggest you include them close to related lines (same paths) for the sake of clarity. After these corrections the build of the RPM packages went on with no errors and was successful. All the packages installed correctly afterward. I hope these tips will be useful to someone. PS - The sources for Samba 3.5.6 are here: http://www.samba.org/ Before building, you might be interested in patching the sources with the patch provided by Volker Lendecke to improve compliance with Windows ACLs. The patch is here, thanks to Volker: http://samba.org/~jra/samba-3-5-x-acl-jumbo-patch.tgz patch -b -p1 < jumbo-patch-3-5-6.diff After applying the patch and modifying the .spec file you can proceed to the building process. cd to "/usr/src/redhat/SOURCES/samba-3.5.6/packaging/RHEL" and execute the "makerpms.sh" script there.

problem sending/recieving mails
by maina＠linuxmail.org 02 Nov '10

02 Nov '10

Hi all, I ave setup a CentOS server to act as LAN gateway and also as a transparent proxy server but all client "passing through" that server are enable to send or recieve mails. The mail server is host on the same LAN running mdaemon, both servers are on private IP block(192.168.0.0/24). Am using cisco router to do port forwading for mailserver(25,110,143) ports. If i eliminate CentOS box and direct traffic direct to cisco router everything works. My question is why is it when i use CentOS box as LAN gateway clients are unable to send/receive mails? I ave done nating on that box. Centos 5.5 full updated.

grub irritants

It appears that if I do anything to grub.conf, say, take out the rhgb quiet, after every succeding kernel update, I have to manually edit grub.conf, because the kernel update - maybe the post install script? - will set the default to be the previous kernel. Has anyone got a solution to this, so that a kernel update will give the new kernel as the default? mark

Geany plugins out of sync
by Eduardo Grosclaude 01 Nov '10

01 Nov '10

I'm intending to do some version control, hence looking for some plugins. Geany and geany-plugins packages in Rpmforge seem to be out of sync: Name : geany-plugins Arch : i386 Version : 0.18 Release : 1.el5.rf Name : geany Arch : i386 Version : 0.19.1 Release : 1.el5.rf When both are installed, geany claims that plugins are not "binary-compatible". Frank's own hosted geany RPM (http://www.melvilletheatre.com/articles/el5/geany-0.19.1-1.i386.rpm) is even newer, but no geany-plugins there. Any chance for this to be repackaged? Or, some quick & dirty workaround? Thank you very much in advance! -- Eduardo Grosclaude Universidad Nacional del Comahue Neuquen, Argentina

migrating users to openldap
by Tim Dunphy 31 Oct '10

31 Oct '10

I noticed that when I migrated my users with the migrate_passwd.pl tool from PADL it didn't migrate the actual passwords (just the rest of the posixAccount info). I think I need to set the EXTENDED_SCHEMA variable and then try running the tool again. does anyone know what this should be? I actually thought there might be a migrate_shadow.pl tool that could accomplish this, but there doesn't appear to be anything like that among the PADL migration tools. So in short the user info is there in LDAP but no one can log in because all the password fields look like this: userPassword: {crypt}* Here is a more complete user entry that is currently in the system: 73 uid=bluethundr,ou=summitnjops,ou=staff,dc=summitnjhome,dc=com uid: bluethundr cn: Timothy P. givenName: Timothy P. sn: Dunphy objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson objectClass: posixAccount loginShell: /usr/local/bin/bash uidNumber: 1001 gidNumber: 1002 homeDirectory: /home/bluethundr gecos: Timothy P. userPassword: {crypt}* thanks in advance for any tips you can share that will get this working! -- Here's my RSA Public key: gpg --keyserver pgp.mit.edu --recv-keys 5A4873A9 Share and enjoy!!

How to access one machine behind iptables, on different subnet?
by Rudi Ahlers 29 Oct '10

29 Oct '10

Hi all, I wonder if someone can help me with this: The setup is as follows: 192.168.1.254 - wireless ADSL modem, with DHCP pool on 192.168.100 - 192.168.200 192.168.1.250 - Linux firewall RED interface 192.168.2.250 - Linux firewall GREEN interface. There are some normal LAN clients behind the Linux firewall's GREEN interface, which can all access each other's shared services and also all the clients behind the RED interface. i.e. those clients connected to the 192.168.1.254 ADSL wifi APP directly. Now I want the clients on the "outside" to connect to one specific host on the inside, behind the GREEN interface, on IP 192.168.1.20. How would I do that? I know I can do this with port fowarding, but need many ports forwarded. How do I give full access to all ports on this IP, instead of forwarding every port? Does that make sense? Currently no clients on the 192.168.1.0 subnect can access any client on the 192.168.2.0 subnet.

faster fsck ?
by przemolicc＠poczta.fm 29 Oct '10

29 Oct '10

Hi, we have CentOS ftp server (vsftpd) which has a lot of users who are writing and reading a lot of small files from/into its own accounts (and other servers - using samba client - are reading these files and putting them into outside database). Since this server is under heavy load its availability is important. >From time to time we "crash" this server (don't ask why ...) but then fsck is running for over 20-30 minuts. The question is: is there any other _stable_ filesystem (xfs ?, jfs ?) which we can use instead of ext3 which is (quite) immune to crashes and whose fsck is "faster" (by design) then in ext3 ?

Just wondering if anyone might be seeing any similar frequent crashes of Firefox/GNOME/Nautilus lately. I have a couple of users who have reported a problem like this. Any ideas are welcome.

CentOS 5.5: bind config is missing the slave zone definitions
by Boris Epstein 29 Oct '10

29 Oct '10

Hi all, I have two near identical CentOS 5.5 machines; both are running named server (DNS). On one using system-config-bind I can easily define a slave zone; on the other, it is a no go: it says the definition is there, etc. but there is no corresponding file in /var/named/chroot/var/named/slaves . Any idea why that would be? What gives? I use the simplest possible zone definitions - forward IN slave, one forwarder. Thanks. Boris.

ssh with shared home dir
by Tim Dunphy 28 Oct '10

28 Oct '10

hey listers! silly quesion: if I generate an RSA key on an NFS shared home directory, then cat >> it into the .ssh/authorized_keys file in the same location, shouldn't I then be able to ssh into each host that shares the NFS home directory without entering a passphrase (assuming the key doesn't have one)? and assuming the permissions on the authorized_keys file belong to the user with mode 600? thanks! tim -- Here's my RSA Public key: gpg --keyserver pgp.mit.edu --recv-keys 5A4873A9 Share and enjoy!!

CentOS 5.x on Geode LX
by Tim Nelson 28 Oct '10

28 Oct '10

Greetings all- I'm currently working with CentOS 5.x (various version 5.0 - 5.5) attempting to run it on a system based on the AMD Geode LX CPU. There are known issues with this CPU running Centos 5, specifically those listed here: http://bugs.centos.org/view.php?id=2552 The kernel and system run fine on the Geode LX, but the installer detects the CPU as i586. Since there is no i586 kernel package available, the installer dies. I've attempted the workaround here: http://lists.baseurl.org/pipermail/yum-devel/2009-August/005767.html It basically tells anaconda the CPU arch is i686. I extracted the stage2.img, updated the specified files, then recreated the squashfs image. But, it still does not work. Apparently this works on Fedora... So, does anyone have any thoughts on getting CentOS 5.x to install on a Geode LX? Tim Nelson Systems/Network Support Rockbochs Inc. (218)727-4332 x105

necessary/unused rpm packages
by Alice Anderson 28 Oct '10

28 Oct '10

Is there a way to identify if an rpm package is unused, or how much it is used? I would like to reduce my load time by removing unused packages in my kickstart, but do not want to cause problems for users on active systems by guessing which ones are not necessary (I load everything with kickstart now). If I could find the packages are not used I could start by excluding them from a load and be fairly certain my users would not be impacted.

interesting kvm lvm collision issue
by Iain Morris 27 Oct '10

27 Oct '10

I've been running into a reproducible problem when using default LVM volume group names to present block devices for virtual machines in KVM, and I'm wondering why it is happening. On dom0 I make a default VolGroup00 for the operating system. I make a second VolGroup01 for logical volumes that will be block devices for virtual systems. In VolGroup01, I make two lv's for one system: lv.sys1, and lv.sys1-data. I then build a new virtual machine called sys1, using lv.sys1 for the root filesystem, and lv.sys1-data for an independent data partition. Everything works great after installation, and vgdisplay on both systems looks great. If I then run vgscan, however, on the host system, it picks up the VolGroup01 I created _within_ the virtual machine, so I now have 2 VolGroup01's with different UUIDs showing up on dom0. Now I can see how vgscan would mistakenly see the VolGroup01 of sys1 on the block device lv.sys1-data, but why are the VolGroup00 vg's not colliding as well? When a pvdisplay is run, I have a new "physical volume" that is actually just a logical volume of the original VolGroup01: [root@iain2 ~]# pvdisplay WARNING: Duplicate VG name VolGroup01: Existing FNiKc9-BB3t-ziMg-prWW-n8RA-OMzk-obiKnf (created here) takes precedence over C8fNMV-aeSW-syIn-fWJZ-vJdK-N0As-Itrvfi WARNING: Duplicate VG name VolGroup01: Existing FNiKc9-BB3t-ziMg-prWW-n8RA-OMzk-obiKnf (created here) takes precedence over C8fNMV-aeSW-syIn-fWJZ-vJdK-N0As-Itrvfi --- Physical volume --- PV Name /dev/VolGroup01/lv-sys1-data VG Name VolGroup01 PV Size 40.00 GB / not usable 4.00 MB Allocatable yes (but full) PE Size (KByte) 4096 Total PE 10239 Free PE 0 Allocated PE 10239 PV UUID FTA4QU-ydZ7-e2Yy-nBsi-t4st-3jj7-IAkQH8 --- Physical volume --- PV Name /dev/sda3 VG Name VolGroup00 PV Size 39.06 GB / not usable 29.77 MB Allocatable yes (but full) PE Size (KByte) 32768 Total PE 1249 Free PE 0 Allocated PE 1249 PV UUID tTViks-3lBM-HGzV-mnN9-zRsT-fFT0-ZsJRse --- Physical volume --- PV Name /dev/sda2 VG Name VolGroup01 PV Size 240.31 GB / not usable 25.75 MB Allocatable yes PE Size (KByte) 32768 Total PE 7689 Free PE 5129 Allocated PE 2560 PV UUID ZE5Io3-WYIO-EfOQ-h03q-zGdF-Frpa-tm63fX Has anyone experienced this? It's very unnerving to know your data is intact as you add new logical volumes for kvm systems. I suppose the lesson learned here is to provide VGs with specific host names. -- -- - Iain Morris iain.t.morris(a)gmail.com
