It pings fine (so I know that connections can be established over the physical wires) and on the IP address telnet answers. However, telnet to port 25 (smtp) with the domain name fails.

Why WOL? ( WAS: Re: Getting Wake on lan to work )
by Drew 21 Oct '10

21 Oct '10

On a semi-related subtopic, Why do I want WoL? What concrete examples are there where it's useful? I understand what it is and how it works but the "why" has eluded me. -- Drew "Nothing in life is to be feared. It is only to be understood." --Marie Curie

chroot from 32-bit to 64-bit filesystem?
by Scott Johnson 21 Oct '10

21 Oct '10

I have a 32-bit PXE environment and I want to chroot to a CentOS x64 root filesystem. Of course that doesn't work. Any tricks or hacks that would allow me to do that? Currently I get the error: chroot: /bin/bash: Exec format error What if I updated my PXE environment to 64-bit. Could I then chroot to a 32-bit? I use PXE to quickly troubleshoot both 32-bit and 64-bit arch. Thanks. -Scott

excel parser (preferably perl)?
by Les Mikesell 20 Oct '10

20 Oct '10

I'm getting tired of converting spreadsheets that someone else updates to csv so my perl scripts can push the data into a mysql database. Is there a better way? I haven't had much luck with perl-Spreadsheet-ParseExcel (and find it odd that yum prefers the .32 version from epel over .57 from rpmforge anyway). Is the current CPAN version better? Or the equivalent java tools? Or maybe a scripted OpenOffice conversion would be possible. Needs to deal with both xls and xlsx formats, the odd characters that are confused with quotes even after csv conversion, numbers with $'s and commas embedded, excel's date formatting nonsense, etc. -- Les Mikesell lesmikesell(a)gmail.com

pdflush kernel thread pops up every 10 seconds or so and video decoding grinds to a halt for 1/2 a second
by Aleksey Tsalolikhin 20 Oct '10

20 Oct '10

Hi. A friend of mine was doing real-time video decoding on Fedora Core 13 and he had a performance glitch (1/2 a second freeze) every 5-10 seconds. "top" showed flush-253:0 process at the moment of the freeze. Major device number 253 corresponds to device-mapper. I advised my friend to re-install his FC13 without LVM, to see if the glitch is related to LVM. After re-installing FC13 without LVM, he is seeing the glitch every 10 seconds, and it shows flush-8:16 where before it said flush-253:0. 8 is scsi disk driver. So it's not an LVM thing... maybe a kernel thing? I suggested he try Fedora 14 beta, as it has a newer kernel. Maybe this kernel thing is fixed in the newer kernel. He also tried CentOS 5.5, and saw a "pdflush" process popping up with the same frequency, and resulting in a similar glitch. Any other suggestions? Best, -at

Getting Wake on lan to work
by Peter Crighton 20 Oct '10

20 Oct '10

My system is: Intel CC820 motherboard (which supports PME# wake up for wake on LAN) 3com 3C905C which also supports wake on LAN via PME# Linux 5.5 The motherboard BIOS is later than one that reports an issue with WOL and this particular network card was fixed. But when I turn off the PC (shutdown or poweroff commands or front panel button), it cannot be restarted via WOL. The network light on the Ethernet card goes off so it looks like power is not being retained on the card. Although both the card and the motherboard have WOL headers my understanding is that these are not necessary if using PME# - is that correct? (I don't happen to have a WOL cable so can't just try one to confirm). How can I make Linux shutdown and leave the Ethernet power on? The common suggestion on the 'net is to remove the "-i" switch from the shutdown script, but it was not present to start with.

Can we use gstreamer bad, ugly and ffmpeg packages ( installed using binary rpms) without any legal problems
by praveenya kumar 20 Oct '10

20 Oct '10

Hi We are using centos 5.3 Operating system. It comes with basic gstreamer setup including gstreamer, gstreamer-tools, gstreamer-plugins-base and gstreamer-plugins-good packages. To support different media formats we had to install gstreamer-plugins-bad, gstreamer-plugins-ugly and gstreamer-plugins-ffmpeg from third party repository like rpmfusion as centos repository is not providing these packages. My question is, Can we use these packages ( bad, ugly and ffmpeg) without any legal or licensing issues? If No, Please tell the legal way of using them. thanks G Praveen

OpenLDAP, PAM, GDM Configuration on CentOS 5.5
by Trevor T Kates 20 Oct '10

20 Oct '10

Hello: I am currently establishing a LDAP installation for my department and hope to get a little help on some of the finer details of the configuration. OpenLDAP 2.3.43-12 is currently installed, configured and running on one of my servers with a few client installations querying authentication information from it. The ppolicy schema has been added to the configuration and a password policy has been added to the directory under "cn=default,ou=Policies,dc=domain,dc=com". Users are able to authenticate properly on the client machines to at least login; however, I have been unable to achieve the following functions: - Force user to change password on first login and display a prompt from gdm to facilitate the change - Lock user account from access and display a message from gdm to that fact These workstations are being used in a restricted mode so that the user may only work within X and may not open a terminal. Any help with this particular problem would be appreciated. Thanks. ________________________________________________________ Trevor T.

Increased memory usage between 4.8 and 5.5
by Bryan Stillwell 20 Oct '10

20 Oct '10

I'm running into a memory problem when trying to switch some web servers that are running centos4.8/x86_64 to centos5.5/x86_64. The new servers running centos5.5 are using a decent amount more memory than the centos4.8 servers. Here's an example from top: --- centos 5.5 --- $ uname -a Linux ws51 2.6.18-194.17.1.el5 #1 SMP Wed Sep 29 12:50:31 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 7799 nobody 16 0 348m 101m 43m S 0.0 2.6 1:10.91 httpd 20285 nobody 15 0 340m 94m 43m S 0.0 2.4 1:11.36 httpd 31734 nobody 15 0 340m 91m 41m S 0.0 2.3 1:13.52 httpd 8904 nobody 15 0 341m 89m 39m S 0.0 2.3 0:35.28 httpd 7353 nobody 15 0 336m 87m 42m S 0.0 2.2 1:21.17 httpd 26097 nobody 15 0 333m 87m 43m S 0.0 2.2 1:28.84 httpd 20765 nobody 15 0 335m 86m 42m S 0.0 2.2 0:48.50 httpd 23299 nobody 15 0 334m 86m 42m S 0.0 2.2 1:13.35 httpd --- centos 4.8 --- $ uname -a Linux ws89 2.6.9-89.0.28.ELsmp #1 SMP Fri Aug 20 16:11:39 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 25117 nobody 16 0 244m 57m 41m S 0.0 1.5 0:58.23 httpd 21318 nobody 15 0 240m 53m 41m S 0.0 1.3 0:53.25 httpd 18517 nobody 16 0 239m 51m 41m S 0.0 1.3 0:41.97 httpd 10383 nobody 15 0 238m 50m 40m S 0.0 1.3 0:31.07 httpd 29560 nobody 16 0 239m 49m 39m S 0.0 1.3 0:40.39 httpd 32459 nobody 16 0 238m 49m 40m S 0.0 1.3 0:23.07 httpd 8441 nobody 15 0 238m 48m 39m S 0.0 1.2 0:22.87 httpd 1350 nobody 15 0 238m 48m 39m S 0.0 1.2 0:29.83 httpd The versions of both apache and php I have installed are the same between the two releases, so I can't imagine that being the problem. I've also tested newer versions and it doesn't seem to make a difference. I've looked into this quite a bit and below is what I've figured out so far. Looking at the output of running 'pmap -x <pid>' shows most of the libraries in 5.5 are using 2044K or 2048K of memory, but in 4.8 they're all using 1024K or less. Example: --- centos 5.5 --- 00002b37c3248000 16 16 0 r-x-- libnss_dns-2.5.so 00002b37c324c000 2044 0 0 ----- libnss_dns-2.5.so 00002b37c344b000 4 4 4 r---- libnss_dns-2.5.so 00002b37c344c000 4 4 4 rw--- libnss_dns-2.5.so --- centos 4.8 --- 0000002aa4a5e000 16 - - - r-x-- libnss_dns-2.3.4.so 0000002aa4a62000 1020 - - - ----- libnss_dns-2.3.4.so 0000002aa4b61000 4 - - - r---- libnss_dns-2.3.4.so 0000002aa4b62000 4 - - - rw--- libnss_dns-2.3.4.so This seems to be explained by an increase in ELF_MAXPAGESIZE between the two releases according to this page: http://www.greenend.org.uk/rjk/2009/dataseg.html Another oddity I found that was only in centos 5.5 was a lot of heap memory being marked as Private_Dirty according to /proc/<pid>/smaps: 2b37c9826000-2b37cc4ca000 rw-p 2b37c9826000 00:00 0 [heap] Size: 45712 kB Rss: 45424 kB Shared_Clean: 0 kB Shared_Dirty: 1580 kB Private_Clean: 0 kB Private_Dirty: 43844 kB Swap: 0 kB Pss: 43913 kB The highest amount of Private_Dirty showing up on 4.8 is just 1628 kB. Does anyone have any ideas on why 5.5 is using so much memory per httpd process than it does in 4.8? I have 100+ machines I want to upgrade, but that'll have to wait until I figure out why apache uses so much more memory in 5.5... Thanks in advance, Bryan

Who maintains php-pgsql package? I want to ask about using PostgreSQL 8.4 library instead of PostgreSQL 8.1.
by Aleksey Tsalolikhin 19 Oct '10

19 Oct '10

How do I find out who is the maintainer of the php-pgsql package, please? I want to request upgrade from underlying postgresql-libs-8.1.21 (/usr/lib64/libpq.so.4) to postgresql84-libs-8.4.4 (/usr/lib64/libpq.so.5.2). Background on this request: Apache httpd's php's php-pgsql uses PostgreSQL 8.1 library (/usr/lib64/libpq.so.4), which leaks memory. PostgreSQL 8.4 library does not leak. Apache HTTP Server: httpd-2.2.3-43.el5.centos.3 mod_php: php-5.1.6-27.el5 PHP PostgreSQL interface is provided by: php-pgsql-5.1.6-27.el5, which uses postgresql-libs-8.1.21-1.el5_5.1 which provides /usr/lib64/libpq.so.4 which we've observed has a memory leak (and this memory leak is NOT present in libpq.so.5.2) I am trying to figure out how to get our httpd/mod_php/php-pgsql to use libpq.so.5.2 instead of libpq.so.4, and I thought I'd start by asking the php-pgsql maintainer, so this problem is fixed for everybody, not just for me. Please let me know if I can help in any way. Kind regards, Aleksey

dhcpd rpm
by m.roth＠5-cent.us 19 Oct '10

19 Oct '10

Folks, We've been having occasional issues with failover dhcpd. I went looking for "peer holds all free leases", and happened to run across <https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=610219>, which is rated important, and is supposed to be fixed in 3.0.5-24. Looking at the repo at kernel.org, all I see is what we have, dhclient-3.0.5-23.el5.x86_64.rpm. Any idea when this update will be released? mark "we won't mention 3.1 or 4.x"

wireless
by David 19 Oct '10

19 Oct '10

Hi folks I have a CentOS box with 2 network cards. One is eth0 and the other is wlan0 (Linksys WUSB54GC USB wifi card) I use wlan0 to stay linked with other workstations in an small network and eth0 just in case I need to get wired to solve some problem. eth0 is always unpluged while things are going ok. Te problem is everytime my AP is turned off for whatever reason or the link is down, no matter the AP is working again, my wlan0 stays without link. Then I have to reboot to get wireless linked again. I'm not running Network Manager, For some reason, everytime I tried to start it, it just mess my network, trying to make wlan0 to get an IP from a DHCP server, no matter wlan0 have it's own IP address specified in ifcfg-wlan0. The Centos Box is unattended and everytime it happens I have to go to the other room and press the on/off button to restart it. (no display, keyboard or mouse in it) Any advices? How could I make NetworkManager to just link it again and not start messing with my network configuration? Cheers David

best practices in using shared storage for XEN Virtual Machines and auto-failover?
by Rudi Ahlers 19 Oct '10

19 Oct '10

Hi all, Can anyone pleas tell me what would be best practice to use shared storage with virtual machines, especially when it involved high availability / automated failover between 2 XEN servers? i.e. if I setup 2x identical XEN servers, each with say 16GB RAM, 4x 1GB NIC's, etc. Then I need the xen domU's to auto failover between the 2 servers if either goes down (hardware failure / overload / kernel updates / etc). What is the best way to connect a NAS / SAN to these 2 servers for this kind of setup to work flawlessly? The NAS can export iSCSI, NFS, SMB, etc. I'm sure I could even use ATAOE if needed -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

Not receiving mail
by Dotan Cohen 18 Oct '10

18 Oct '10

I have installed Postfix, Dovecot, and Squirrelmail on a CentOS 5.5 machine. In Squirrelmail a user can send mail, but he is not receiving replies. There is nothing relevant in the maillog other than the user's (successful) login attempts. I am at loss, I have been following tutorials such as the Perfect Server [1] series and other Google results, but I cannot get this thing to receive mail. What should I be checking? Thanks!

qemu-kvm segfaults on starting guests
by Negative 18 Oct '10

18 Oct '10

I have a Centos 5.5 on an AMD 64 system (Athlon II x2 250). I caught up on updates today, including -- kernel 2.6.18-194.17.1.el5 -- glibc 2.5-49.el5_5.5.i686 I have several guests that were working before the update, but now none of them will boot. With each attempt I get a message in /var/log/messages: -- kernel: qemu-kvm[xx]: segfault at 000000379fc0da11 rip 00002b9f2732283f rsp 00000000446a6e80 error 7 Has this happened to others? Any fix. I see similar bugreports, but they are not recent, and not quite like this. The closest thing I can find was on an nvidia list about vmware posted today -- so maybe this has something to do with needing to rebuild the nvidia drivers with every kernel update. Any ideas?

using a Laptop as a KVM console?
by Rudi Ahlers 18 Oct '10

18 Oct '10

Hi all, Has anyone seen something like this before: I want to use a laptop as a KVM console. Basically when a technician goes to one of our datacentres, or clients he has to look for a free LCD, keyboard & mouse to connect to a server (no network access, reinstall, troubleshoot failed kernel / HDD, etc). And then hopefully there's an open power socker in that cabinet. So I'm thinking why not just use a laptop instead? It already has an LCD, keyboard, mouse & power. Surely someone has, or may still, build something that could connect to the laptop's USB port(s) and then to the server's VGA & USB / PS2 ports, then act as a KVM? -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog: http://Blog.SoftDux.com Office: 087 805 9573 Cell: 082 554 7532

Re: [CentOS] yum list updates error (Manish Kathuria)

There was no proxy in the file /etc/yum.conf. I specified the proxy setting and now "yum list updates" is working. A part of the output was: Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: centos.01link.hk * updates: centos.01link.hk * addons: centos.01link.hk * extras: centos.01link.hk Updated Packages ImageMagick.i386 6.2.8.0-4.el5_5.2 updates ImageMagick.x86_64 6.2.8.0-4.el5_5.2 updates NetworkManager.i386 1:0.7.0-10.el5_5.1 updates Its written Updated Packages. Does this mean it has already updated? I thought that this command displays packages that need to be updated.

iptables: comprehensive tutorial for CentOS?
by Boris Epstein 18 Oct '10

18 Oct '10

Hello listmates, I know this may sound stupid... but I am trying to set up a firewall/filter/forwarder using CentOS 5.5 machine as a platform and I am succeeding but only partially. Fro example, I am literally trying to forward HTTP and HTTPS (TCP 80 and 443) from the public interface to a private IP and TCP 80 works like a charm whereas TCP 443 seems to be a no-go. To that effect: does anyone know of a comprehensive relevant manual? I mean, I must be doing something wrong here though I ain't sure what. Any advice and suggestions much appreciated. Boris.

ip based acl at snmp v3?
by MontyRee 18 Oct '10

18 Oct '10

Hello, all. My system is centos 5.x and I would like to set IP based (acl) accessl-list at snmp verison 3. As I know, at snmp v1/v2c, we can set acl like below. ------ snmpd.conf -------- rocommunity public 127.0.0.1 rocommunity public 10.0.0.1/24 rouser testuser createUser testuser MD5 "passwords" DES --------------------------------------------------- But, how about snmp version 3? I searched and tried, but I could't find the answer. Surely, I can set hosts.deny or iptables, But I want to know how to set acl at snmpd.conf. Thanks in advance.

Ping time resolution
by Mitja Mihelič 18 Oct '10

18 Oct '10

Hi! We have encountered a rather weird problem on a machine that we use for our network latency check (smokeping with fping). For an hour (or so) after boot it reports the ping time with a microsecond accuracy (ad it should). Then the millisecond accuracy starts. We have yet to identify the cause and the logs currently do not show anything. Please find an example of a good and a bad result below. Regards, Mitja When it works: (microsecond accuracy): [root@server ~]# ping test.example.net PING test.example.net (123.1.2.3) 56(84) bytes of data. 64 bytes from test.example.net (123.1.2.3): icmp_seq=1 ttl=62 time=0.562 ms 64 bytes from test.example.net (123.1.2.3): icmp_seq=2 ttl=62 time=0.452 ms 64 bytes from test.example.net (123.1.2.3): icmp_seq=3 ttl=62 time=0.579 ms --- test.example.net ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 1998ms rtt min/avg/max/mdev = 0.452/0.531/0.579/0.056 ms And when it does not (millisecond accuracy): [root@server ~]# ping test.example.net PING test.example.net (123.1.2.3) 56(84) bytes of data. 64 bytes from test.example.net (123.1.2.3): icmp_seq=1 ttl=62 time=1.99 ms 64 bytes from test.example.net (123.1.2.3): icmp_seq=2 ttl=62 time=0.999 ms 64 bytes from test.example.net (123.1.2.3): icmp_seq=3 ttl=62 time=0.000 ms 64 bytes from test.example.net (123.1.2.3): icmp_seq=4 ttl=62 time=0.000 ms 64 bytes from test.example.net (123.1.2.3): icmp_seq=5 ttl=62 time=0.000 ms --- test.example.net ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 3999ms rtt min/avg/max/mdev = 0.000/0.599/1.999/0.800 ms

black display during installation of CentOS5.5
by Ritika Garg 17 Oct '10

17 Oct '10

During installation of CentOS5.3 from DVD, the installation was interuppted due to an error in a rpm package as the DVD had lot of scratches. So I burned image of CentOS5.5 on DVD. I selected installation in graphical mode. The first graphical interface screen comes from where we proceed further by clicking next. This screen is almost black and its impossible to carry out further installation as visibility is very poor.

Another wireless problem
by David 16 Oct '10

16 Oct '10

Hi folks I have my Linksys WUSB54GC USB wifi card already working. Now I have another issue. Accidentally I tuned off my AP, and when switched it on again my wireless link is still down. I have to unplug the USB card and plug it again to get it working again. I'm new in wireless matter but this doesn't sounds logical to me. What if I loose the link for whatever reason? Should I have to unplug my usb card and plug it again? I don't think so, right? So, wich is the workaround here? Maybe there is a service I'm noy running wich detects the when the link comes up and conect automatically again? Thanks in advance David

Trying to get xen to boot off of an iso or a sysresc image so I can expand a filesystem to the extent of the LVM's free space.
by Peter Serwe 16 Oct '10

16 Oct '10

I have a Xen LVM based VM with two partitions: /dev/VolGroup00/vm01p1 /dev/VolGroup00/vm01p2 p2 is about 50GB, I gave it's LVM an extra 30 or so using lvextend. How can I extend the partition to fill my free space and the filesystem? I don't mind offline, if I can get Xen to boot off an alternative media.

I want to update the system because I haven't updated CentOS5.3 from the time when I installed it. But I am also afraid of directly using "yum update" command. I used "yum list updates" but theres a error displayed which I have already posted.

And with 6 coming soon, I was thinking, though I haven't gone to look, that they'd have 3.1 or 4.x.

by Ritika Garg 15 Oct '10

For burning the image on DVD I found 2 iso files: CentOS-5.5-x86_64-bin-DVD-1of2.iso CentOS-5.5-x86_64-bin-DVD-2of2.iso I found out that the first one is 4.1GB and the second one is 412MB. Do I have to burn the first one on 1 DVD and the second one on another DVD?

Routing local generted packets with fwmark
by C. L. Martinez 15 Oct '10

15 Oct '10

Hi all, I need to route local generated packages depending on which tcp or udp service I need to use. To accomplish this I have configured two routing tables: [root@lothlorien ~]# ip ru ls 0: from all lookup 255 32762: from all fwmark 0x2 lookup FirstLan 32763: from all fwmark 0x1 lookup SecondLan 32764: from 172.25.80.10 lookup SecondLan 32765: from 172.25.70.18 lookup FirstLan 32766: from all lookup main 32767: from all lookup default My routing tables: [root@lothlorien net]# ip ro show table FirstLan 172.25.70.16/28 dev eth1 proto kernel scope link src 172.25.70.18 default via 172.25.70.30 dev eth1 [root@lothlorien net]# ip ro show table SecondLan 172.25.80.0/24 dev eth1 proto kernel scope link src 172.25.80.10 default via 172.25.80.1 dev eth2 And my iptables rule is: iptables -t mangle -A OUTPUT -p udp --dport 53 -j MARK --set-mark 1 But this doesn't works. This host is CentOS 5.5 based with two interfaces. What am I doing wrong?? Thanks.

Hi folks I have the command "find . | xargs grep 'mailx'", to search all files with "mailx" in contents. I wish to add a second condition that NOT contains string sven.aluoor(a)ubs.com on the same line. Every file which contains "mailx", but not the string sven.aluoor(a)ubs.com in the same line. cheers Sven
