pam ulimit 64 bit
by Peter van Eck 16 Nov '06

16 Nov '06

Hi, Although this is on RHEL 4 update 2 x86-64 I would like to place the question on this list. I'm trying to set up some shell limits for a user. I've added the user to /etc/security/limits.conf There is an entry in /etc/pam.d/login with pam_limits.so as well as in /etc/pam.d/sshd When I try to set ulimit -n <value> I get : cannot modify limit : Operation not permitted Even if I replace all entries in /etc/pam.d/login with the absolute path to /lib64/security it doesn't work. Any suggestions on where to look now ? thanks, Peter

Firefox 2.0 on CentOS 4.4
by Edward Diener 16 Nov '06

16 Nov '06

I realize that CentOS 4.4 is all about stability but I would still like to install Firefox 2.0 on it, since I am sharing my Firefox project across OSs on a multi-boot machine and the other OSs have Firefox 2.0. Is it possible to get CentOS 4.4 to work properly with Firefox 2.0 and, if so, does anybody know of a CentOS 4.4 repository which has a Firefox 2.0 RPM available.

GPL java
by Jim Perrin 16 Nov '06

16 Nov '06

For the people who are currently interested in java as it relates to centos now that Sun has GPL'd java there are some things to be aware of. The folks at jpackage.org are pretty much all over this development but it's not the bright shiny news everyone has made it out to be. Sun did a very good thing by moving java under the GPL, and they should be commended for FINALLY seeing the light after the failure of the DLJ license BUT: 1. Sun did not open all of java under the GPL. There are still several chunks of java which remain license encumbered and will require community workarounds or further moves by Sun to open code. Currently these include the color management code, font rasteriser code, graphics rasteriser code, and several more. 2. Sun is not opening up the Java trademark, so any GPL'd distribution of java will not be called 'java', but something else. I've heard that iceweasel is taken, so I don't know what the next best option is. The fine folks at jpackage are working the details further. This basically means that for the time being, there will not be a gpl'd jdk in centos4, and packages will have to be distributed under the DLJ license (which I am not a fan of) or obtained from java.sun.com and used in conjunction with the jpackage sun-java-compat packages for best performance. -- During times of universal deceit, telling the truth becomes a revolutionary act.

tar vs. star vs. something-else-I-don-t-know-about
by Alexey Loukianov 16 Nov '06

16 Nov '06

Hello all, today I've been sitting at work and upgrading a very-very-very old server with RedHat Linux 6.2 installed up to CentOS 3.8. The process went smoothly, as it is not the first time I was doing the things like this. Just after upgrading I went to rpm -qai list and got an interesting observation: there are at least two "tar" utilities installed on the system. One is tar, and second is star. [root@devel mrtg]# rpm -qi star Name : star Relocations: (not relocatable) Version : 1.5a08 Vendor: CentOS Release : 4 Build Date: Вск 29 Фев 2004 04:54:14 Install Date: Пнд 13 Ноя 2006 09:38:38 Build Host: centos3.wellhouse Group : Applications/Archiving Source RPM: star-1.5a08-4.src.rpm Size : 336744 License: GPL Signature : DSA/SHA1, Втр 16 Мар 2004 01:48:38, Key ID 7049e44d025e513b URL : http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private… Summary : An archiving tool with ACL support Description : Star saves many files together into a single tape or disk archive, and can restore individual files from the archive.

Description : The GNU tar program saves many files together in one archive and can restore individual files (or all of the files) from that archive. Tar can also be used to add supplemental files to an archive and to update or list files in the archive. Tar includes multivolume support, automatic archive compression/decompression, the ability to perform remote archives, and the ability to perform incremental and full backups. If you want to use tar for remote backups, you also need to install the rmt package. I would like to know, what are the differences between them? Which one should I use in the future? Is star compatible with amanda backup suite (I use amanda as a main backup software solution for our production environment servers)? Also, there may be other tar-like/compatible utilities shipped with CentOS3/4 that I simply don't know about. It would be great, if somebody will provide me with info (or a link to a place) about such utilities, and with a comparison between them all. Thanks in advance. -- С уважением, Alexey mailto:aloukianov@lavtech.ru

About download ISO image, again
by Stephen Liu 16 Nov '06

16 Nov '06

Hi folks, It comes to my notice that there is an server version - CentOS-4.4.ServerCD-x86_64.iso http://mirror.myriadnetwork.com/centos/4.4/isos/x86_64/ I'm going to run CentOS as server. What packages are included there? Is X packages included as well which should not be on a server creating a risk hole. However on another hand it will be convenient for me at the early stage of installation to search documents on Internet. Just retain X not started at boot and remove all their packages after installation finished. I don't expect connecting a workstation to the server to do this job at the beginning. Advice would be appreciated. TIA B.R. Stephen

hard drive failing in linux raid
by Joseph Cheng 15 Nov '06

15 Nov '06

Hello all. I have a server with a linux software raid1 setup between two drives of the same model....one hard drive as primary ide master and second hard drive as secondary master. Now primary master hard drive is displaying a lot of SMART errors so I would like to remove it and replace with another drive....different brand but same size. Partitions are /dev/md0 till /dev/md5. I think I know what to do based on mdadm man page and this list's archives but there is no harm in confirming right? ;) From this post http://lists.centos.org/pipermail/centos/2006-April/063076.html I plan on removing the old partitions from the array like this..... mdadm /dev/mdx -r /dev/hdax. Then I will shut down the server, replace the hard drive, make the server boot from second IDE drive and hopefully boot into Centos. From there do I have to manually create each /dev/mdx partition and then re-add them like this....mdadm /dev/mdx -a /dev/hdax ? That is what I am not sure about whether I have to partiton the drive exactly like the old one or if Centos mdadm can do some magic for me with a blank drive. TIA!!

sshd logging with GMT times?
by David Mackintosh 15 Nov '06

15 Nov '06

Hi folks, while chasing down a logging-related situation, I happened to notice that when I connect via ssh to my system it makes the following logs: Nov 15 14:15:39 saturn sshd[29868]: Accepted password for dave from ::ffff:10.0.10.14 port 2833 ssh2 Nov 15 09:15:39 saturn sshd[29867]: Accepted password for dave from ::ffff:10.0.10.14 port 2833 ssh2 Nov 15 09:15:39 saturn sshd(pam_unix)[29869]: session opened for user dave by (uid=0) That is, sshd appears to log the connection with GMT (or UCT) before the child sshd logs it with local time. This is messing up one of my reporting processes, since I have syslog-ng configured to produce a new file for every day, and at the end of the day I try to scan the newest file for the day's events. So if I ssh to the system after 7PM local time, the "newest" file is the one from "tomorrow" which has the GMT timestamped entries, not the entries from today. How do I either tell sshd to always use local time, or tell it not to make the first entry? -- /\oo/\ / /()\ \ David Mackintosh | Public Key: dave(a)xdroop.com | http://www.xdroop.com/dave/gpg.html $ gpg --recv-keys --keyserver subkeys.pgp.net 4C032504 Mystery attachment? http://wiki.xdroop.com/space/GPG

System crashed & LVM1
by Guy Boisvert 15 Nov '06

15 Nov '06

Hi all! I'm new to this list. I wanted to have an opinion of the situation i'm facing now (i'm no expert in LVM). Last week, i had to re-install a system which had a system hard drive crash (it was clunking before it definitely died!). It was running on SuSE 9.0 before. I just finished to install a fresh copy of CentOS 4.4 on a new hard disk. I want to know if it's possible to "import" the old LVM array into the fresh CentOS install. We have 1 volume group (LVM1) that contains 3 whole hard drives. I had the time to save some informations before the system hard drive crashed definitely: I have vgcfgrestore info, i have volgroups_001.conf, i have the full /etc directory and pvdata.

stange lockd issue on CentOS 4.4
by Alexey Loukianov 15 Nov '06

15 Nov '06

Greetings, CentOS. After up2dating one of the corporate mail servers to CentOS 4.4 (was CentOS 4.2) and upgrading kernel to kernel-smp-2.6.9-42.0.3.EL, the following kernel messages started to appear in syslog: [root@gamma ~]# dmesg ........... ...CUT..... ........... lockd: unexpected unlock status: 1 lockd: unexpected unlock status: 1 lockd: unexpected unlock status: 1 lockd: unexpected unlock status: 1 lockd: unexpected unlock status: 1 lockd: unexpected unlock status: 1 lockd: unexpected unlock status: 1 lockd: unexpected unlock status: 1 lockd: unexpected unlock status: 1 lockd: unexpected unlock status: 1 lockd: unexpected unlock status: 1 lockd: unexpected unlock status: 1 lockd: unexpected unlock status: 1 lockd: unexpected unlock status: 1 lockd: unexpected unlock status: 1 lockd: unexpected unlock status: 1 lockd: unexpected unlock status: 1 lockd: unexpected unlock status: 1 Rebooted with an older kernel (2.6.9-34.0.2.ELsmp), but the problem persists. This server utilizes NFS share as a storage volume for user mail boxes, the NFS server is also a CentOS 4.4 server, also with the kernel, up2dated to kernel-smp-2.6.9-42.0.3.EL few weeks ago. As this is a production environment, I can't simply go and reboot NFS server to an older kernel - this would lead to a small amount of downtime, which is undesirable for me. Could someone help me to understand what does that messages mean, why did they appear, and what caveats they may cause to me except for spammed syslog? Thanks in advance. -- Best regards, Alexey Loukianov mailto:aloukianov@lavtech.ru Software Development Department, Lavtech Corp http://mnogo.ru, http://lavtech.ru

Benchmarking DNS and DHCP
by Ian Anderson 15 Nov '06

15 Nov '06

Does anyone know of any FOSS tools that can assist in benchmarking ISC DNS and DHCP services? I would like to simulate X number of users attempting to pull an IP, resolve DNS names, etc. I would also like to test TCP connections into a CentOS server. We have some software that communicates with equipment via a TCP connection and I want to simulate thousands of TCP connections coming into one server. Any suggestions are welcome.

fetchmail problem
by Rajeev R Veedu 15 Nov '06

15 Nov '06

In my fetchmail setup it will fetch only 99 mails at a time. And if the mail numbers are more than 99 it fetch up to 99 and look back same e-mails again and again. (It won't delete the fetched mails) Could someone please help me how to fix this problem? Is there any setting in the fetchmail.rc file that default number of mails to be fetched in a go is max 99 or something like that? Or is there any other package which does the same job? If I could fix this problem I am quite happy to use fetchmail. Thanks Rajeev

OT: Q: Howto implement a monitored Shell for remote logins
by Sanjay Arora 15 Nov '06

15 Nov '06

I sometimes need to allow sub-contracted admins root ssh access to my servers. Later, I always wonder what they did during access. Is there any shell that provides all shell abilities to the remote user but monitors/emails a designated user each command executed in the shell terminal and does not allow the user (even root) to modify the bash history file or similar shell history file, or maybe sending each command by email to a remote server, so that modifying history becomes out of question? Hope someone can help. With regards. Sanjay.

> Scenarios are: > - ipsec-tools with Cisco vpn client Hmmm... I only run non-graphical servers and ipsec-tools without RH gui gives me a major headache... > - pptpd with Windows XP native client We ran this and it works fine, but throughout it's life had to do lot's of patching and kernel recompiling. Not sure if that is the case now as we've moved on. Two other MAJOR issue with this: 1: is that it's password based and if you allow users to pick passwords then be prepared for compromise. 2: you cannot have more than one connection to the same server from behind NAT. We'd always run into this with tradeshows ;) all the reps would stay at the same hotel and only one could use the vpn at a time. Get ready for a lot of upset reps (of course you may not have this issue) > - OpenVPN with OpenVPN Windows client Very slick, add rpmforge repo, yum install openvpn and go to town. I have no major complaints with this system and it's very NAT friendly compared to the other two options. My 2 cents, alex

I am getting a missing dependency message for libx264.so.54 is needed by package mplayer. The yum check-update for packages doesn't even show mplayer is to be updated. That library is in /us/bin on my system and when I run the mplayer that I have that's allready installed it runs fine.

Deleting packages
by Edward Diener 13 Nov '06

13 Nov '06

When choosing to delete packages, Synaptic will tell the user what other packages are dependant and therefore have to be added to the delete list also, and then will automatically add those dependant packages to the delete list if one chooses to go ahead with the original package deletion. I did not notice such functionality in YumEx. Does it exist ? If it does not exist, is it possible to use Synaptic under CentOS 4.4 with the rpm repositories and have it work correctly ? In general I like the Synaptic interface and functionality better than the YumEx functionality. I do understand that there is an updated version of YumEx for Yum 3.0+, but since CentOS is still on an earlier version of Yum, it can not be used.

CUPS disabling a print queue between jobs
by fredex 13 Nov '06

13 Nov '06

Hi! on centos 4.4 (fresh install) I've got a problem with CUPS disabling a print queue between jobs. Sometimes it will print dozens of jobs before disabling the queue, sometimes it will do it after every job. This is a networked HP Laserjet printer at work. At home on a 4.4 box (upgraded from 4.3) with a local (parallel port) printer I've not seen this problem occur. (of course, I don't print as much on the printer at home, either.) I see this bug in the cups bug tracker: http://www.cups.org/str.php?L1648 and it sounds as if it might be the same thing, though it is against cups 1.2, while Centos appears to have 1.1.22. Can anyone shed any light on it, especially how to make it stop happening?

Today i got it down because of an attack, here is the last snapshot of top command before server dies 09:47:30 up 21 days, 6:54, 1 user, load average: 363.88, 727.82, 253.42 3949 processes: 135 sleeping, 3800 running, 14 zombie, 0 stopped CPU states: cpu user nice system irq softirq iowait idle total 0.6% 0.0% 99.2% 0.0% 0.0% 0.0% 0.0% cpu00 0.4% 0.0% 99.4% 0.0% 0.0% 0.0% 0.0% cpu01 0.8% 0.0% 99.0% 0.0% 0.1% 0.0% 0.0% Mem: 2055236k av, 1935836k used, 119400k free, 0k shrd, 188120k buff 1286892k actv, 165568k in_d, 17336k in_c Swap: 2040244k av, 22676k used, 2017568k free 901000k cached PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME CPU COMMAND 6515 root 19 0 10048 9.8M 2612 R 3.9 0.4 1:06 1 cpsrvd-ssl 7175 root 18 0 564 564 492 S 2.7 0.0 0:03 0 couriertcpd 10365 nobody 19 0 11020 10M 2352 R 2.5 0.5 0:08 0 httpd 1998 root 19 0 10724 10M 2140 R 2.4 0.5 3:02 1 httpd 10719 mailnull 19 0 1892 1892 1548 R 1.8 0.0 3:49 0 exim 7169 root 19 0 552 552 476 R 1.8 0.0 0:10 1 couriertcpd 29384 manmoud 25 0 380 380 308 R 1.0 0.0 0:01 0 2-4-21 26278 manmoud 24 0 420 420 308 R 0.9 0.0 0:01 1 2-4-21 26519 manmoud 25 0 420 420 308 R 0.9 0.0 0:01 1 2-4-21 26524 manmoud 25 0 424 424 308 R 0.9 0.0 0:01 1 2-4-21 29368 manmoud 25 0 412 412 308 R 0.9 0.0 0:01 1 2-4-21 25916 manmoud 24 0 388 388 308 R 0.8 0.0 0:01 0 2-4-21 25922 manmoud 25 0 388 388 308 R 0.8 0.0 0:01 0 2-4-21 Clearly, the user manmod caused this huge load.

Alpha Server 1000A 5/400 Centos 4.3 instal can not find the hard drives.
by Stewart Walker 11 Nov '06

11 Nov '06

During the install of alpha Centos 4.3 I'm told by the Centos installer that the hard drives can not be found. Hard Drives have been properly configured in the ARC setup. ARC initialization of the drives works fine. I can create windows nt partitions Went thru the list of drivers provided by Centos but the installer has already loaded the the QLogic and Mylex DAC960 controller drivers. I opened the box and found the controller is really a Mylex controller card . I'm a little confused about the QLogic as it is integrated on the mother board. Something is missing. What? Any help would be greatly appreciated.
