package 'synchronization' for multiple systems
by Tim Alberts 08 Feb '08

08 Feb '08

I'm setting up multiple systems and ideally I want the same package configuration on all of them. So I'm going through yum and rpm queries manually to try and get this done. There must be a better way. Is there a way to use yum or rpm to configure multiple systems with the same packages? If yum or rpm has something native built into it to do this, that would be great. If there's some scripts to simplify some tasks that works too. I've used webmin's 'Cluster Software Package' module, and will probably fall back to it. However I don't think I get the info that yum gives regarding package grouping and what packages are part of what capabilities. Gotta query elsewhere for it. (no disrespect to webmin folks, great tool)

Using tcpdump to sniff telnet password
by Fajar Priyanto 08 Feb '08

08 Feb '08

Hi all, As long as I can remember reading various articles/docs, they all say that telnet is not secure because all traffic is in clear text. Well, out of boredom, I try to sniff username and password from a telnet session. The command I use: tcpdump tcp port 23 -vvv -w test.txt Then I read the result: strings test.txt |`D |fD |fD 38400,38400 Red Hat Enterprise Linux ESD Ologin: D 5eE LsE _tE Password: F [aG |hG jaH Last login: Wed Feb 6 15:53:3H ]0;test4@server:~ GV{ But it succeeds with FTP. strings test.txt <.9@ 4.:@ 220 (vsFTPd 2.0.1) 4.;@ @.<@ USER test4 331 Please specify the passwor 4.=@ B.>@ PASS secret 230 Login successful. 4.?@ :.@@ SYST 215 UNIX Type: L8 4.A@ Did I miss something?

POSIX semaphores in CentOS 5.1?
by MHR 07 Feb '08

07 Feb '08

According to the man pages for sem_wait, etc., POSIX semaphores are available in Linux 2.6 (with the right NTPL threading in glibc). However, I have a program that compiles just fine but won't link because it can't find the library for the semaphore operations. What am I missing? I ran a find and grep through all the libc's on the system and they turned up nothing: $ find /lib /usr/lib -name "*libc\.*" -print -exec nm {} 2>/dev/null \; | grep sem_ (no results) Time is critical (yeah, I know...). Thanks. mhr

poppler-utils missing pdftoppm

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I found a thread here about this problem, but no answer or resolution as to whether it's a bug, or even something that can be fixed. <http://www.centos.org/modules/newbb/viewtopic.php?topic_id=12114&forum=38> I'm trying to get PDF support under DocMGR to work correctly and it's complaining about pdftoppm being missing. A bit of Googling and I found where pdftoppm is supposed to be included with poppler-utils package. I check on my FC 7 system which is running poppler-utils poppler-utils-0.5.4-7.fc7, and pdftoppm is physically there and located in /usr/bin. I'm running CentOS 5 with poppler-utils-0.5.4-4.3.el5_1.

Samba GUI interface
by Dean Maluski 07 Feb '08

07 Feb '08

CentOS 5.1 I was just trying to add users and shares to Samba from GUI interface. I've already added users from command line. Regardless, when I go to select users the existing users is blank. When I add a user if it already exists I get a complaint that user exists. If I add a new user from GUI it does not get added to the blank list. OK I just added a user from gui, applied it [HIT OK] went back and tried to add user again but when hitting [OK] complained that user exists. Seems things are working except listing existing users in interface. I can live with this but I'm about to upgrade a server at work and ultimately I was hoping my Windows Sys Admin could manage to administrate Samba. I don't think this will be possible without a GUI.

Set hardware clock manually
by Joseph L. Casale 07 Feb '08

07 Feb '08

I can't reboot a server to set the hardware clock to UTC time, but CentOS was installed with the assumption that the PC was running UTC. Is it possible to update the hardware clock to the right time and therefore allow CentOS to maintain the right time without rebooting? I am hoping to use this route for consistency versus changing how CentOS interprets the time so all servers are the same. Thanks! jlc

system smtp server question
by Joseph L. Casale 07 Feb '08

07 Feb '08

If I have a production mailserver and a series of Linux servers that all develop mail from logging etc, it seems slightly redundant to have so many smtp servers installed on each of those boxes simply forwarding mail as I choose to not have local delivery. Is there a mechanism possible in CentOS to setup a pointer to a different mailserver such that programs like mailx could still send mail? Currently I have postfix setup with maps so that root on server A has mail sent from root(a)server-a.fqdn<mailto:root@server-a.fqdn> and that is relayed to my production box. It just seems like it is an additional service to manage on so many hosts? Thanks! jlc

64 bit and 32 bit are mixed up
by Centos 07 Feb '08

07 Feb '08

Hello I have installed Centos 5.1 on 64 bit servers, and I see some of the packages have been installed two times, one for i386 and one for 64 bits. I don't know why i386 packages can be installed on 64 bit machine and why they should come together, even some times when I am searching yum repository , I see i386 and x64 packages. shouldn't the search result depend on server architecture ?

drbd82 RPMS for testing
by Johnny Hughes 07 Feb '08

07 Feb '08

All, There are drbd82 RPMS for CentOS-4 and CentOS-5 (i386 and x86_64) for testing here: http://people.centos.org/~hughesjr/drbd/ These are designed to be able to live in the same repository as the current STABLE versions. These RPMS are designed as CONFLICTS and not upgrades as there may be some manual actions to upgrade, especially on CentOS-4. Here is an article on the upgrade process: http://fghaas.wordpress.com/2007/10/03/step-by-step-upgrade-from-drbd-07-to… also this thread about potential upgrade problems: http://lists.linbit.com/pipermail/drbd-user/2008-January/008318.html (We have 8.2.4, so should not have this issue ... but just in case). The process will be similar for drbd-8.0.x to drbd82-8.2.x upgrades as well. Please report successful uses of the RPMS (upgrades and new installs) and any problems here: http://bugs.centos.org/view.php?id=2657 Here is a post to the DRBD mailing list for reference as well: http://lists.linbit.com/pipermail/drbd-user/2008-February/008473.html Thanks, Johnny Hughes

RPM for perl-svn-notify?
by J. Potter 07 Feb '08

07 Feb '08

Hi List, Is it possible to get an rpm built and added into the plus or dag repos for the perl module svn-notify? (Note: not the same as svn- notify-mirror.) I know it's been brought up before that perl's internal CPAN build/ install can cause serious conflicts with the rpm-based approach; if there are other / better ways of doing this in a standard fashion, please let me know. Thanks, Jeff

Seamonkey (with plugins) as Firefox replacement?
by Niki Kovacs 07 Feb '08

07 Feb '08

Hi, I'm running CentOS 5.1 with the GNOME desktop in all our public libraries around here. I start from a minimal install stripped down to the bones, install X11, GNOME, and then one application per task. I try to follow some best-of-the-breed logic, and my focus lies on robustness to avoid the Tamagotchi syndrome :o) Recently I've been rather disappointed with Mozilla Firefox, which crashes more and more often (this has already been developed elsewhere on this list). On one of my machines, I'm running Slackware Linux 12.0, with an XFCE desktop and the latest Mozilla Seamonkey browser. This browser gives me entire satisfaction: light on RAM, fast, and (almost) never crashes. So the idea is simple: install Seamonkey instead of Firefox. Now I'd like to integrate things cleanly, not install it additionally to Firefox. My main concern now are plugins, namely Flash (flash-plugin) and MPlayer (mplayerplug-in, never knew why that hyphen wandered off :o)). I'd like to do things cleanly, so I have a vague idea. Tell me if this sounds reasonable: 1) Install Seamonkey from latest SRPM. 2) Install flash-plugin from SRPM, but modify the .spec file so it depends on Seamonkey instead of Firefox. 3) Do the same thing with the MPlayer plugin. 4) (I never succeeded to install the Java plugin, I guess I'll leave that for after I'm dead :o/ ) Eventually, create my own repo with the resulting RPMS, and define priorities for Yum so that my own packages are used first. Sounds feasible? Or does someone have a better suggestion? Cheers, Niki

by Scott Ehrlich 07 Feb '08

07 Feb '08

I'm looking at building a small cluster of disk-less 1 or 2U servers and will probably use CentOS 5. Since these machines will not have any hard drives, what would be the minimum amount of RAM I'd need? Also, if using Rocks or something similar, will that help cluster the RAM together so 4 servers x 4 GB RAM each = 16 GB available? Some applications might be CPU intensive, others might be RAM intensive, so I need to play that balance, too. Thanks. Scott

What's the best way to do this? Daily, jpg images are added to an inhouse server. Everynight I want to backup these images to a server offsite, via rsync. What I want is to determine what to set the bwlimit to. I also want to estimate how many MB's of images I can move nightly. Thanks Dan

PCNS for CentOS and APC ups's
by Joseph L. Casale 07 Feb '08

07 Feb '08

Apparently there is only an Itanium client for RHEL according to APC? I need to setup a few boxes to shut down safely and don't know if the PCNS 2.2.3 Linux version will do it? Anyone know why it needs Java as well? (Blegh) Assuming APC is fairly popular, how do you guys shutdown your CentOS boxes with a UPS with a management card in it? Thanks! jlc

Re: [CentOS] PCNS for CentOS and APC ups's
by Ross S. W. Walker 07 Feb '08

Well I'm not near the config, but I remember it was easy. The default timings match APC's defaults, so all you really need to do is set the UPS name (for identification purposes) and the comm type will be snmp, port will be something like <hostname>:161:<community> and set an email address to send alerts to. Testing is a little tricky as it dials directly in to the snmp interface, you could lower the "time on battery" and kick the plug on the ups and see if it initiates a safe shutdown, but that depends on how many other hosts are on the ups and if this host is in active production. It has worked in my environment though. -Ross ----- Original Message ----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: centos(a)centos.org <centos(a)centos.org> Sent: Wed Feb 06 18:50:23 2008 Subject: RE: [CentOS] PCNS for CentOS and APC ups's >I use apcupsd from epel > >-Ross Reading about that now, it sounds a lot cleaner then that silly java based one from APC.

Installation problems with large mirrored drives
by Bowie Bailey 06 Feb '08

06 Feb '08

I am trying to install CentOS 4.6 to a pair of 750GB hard drives. I can successfully install to either of the drives as a single drive, but when I try to use both drives and mirror the partitions, I start having problems. Anaconda crashes as it is trying to format the drives. This is what I'm trying to create: /dev/md0: 200MB, /boot /dev/md1: 2GB, swap /dev/md2: rest of the drive, LVM PV LogVol00: 10GB, / LogVol01: rest of the VG, /home I uploaded the anaconda log to the CentOS bugtracker, but I don't know if or when I should expect a response from that, so I'm asking here as well. If you want to see the log, here's the link: http://bugs.centos.org/view.php?id=2652 Is there a way I can work around this problem? It has been suggested that I build the system with a single drive and then add the mirror to it. Is it possible to add a mirror to a partition that is an LVM PV? Can someone give me a link to a good set of instructions for doing this? Thanks, -- Bowie

sendmail: fatal message, sudo bash
by Farid Hamjavar 06 Feb '08

06 Feb '08

Centos 5 Hello I successfully converted my mta from sendmail to postfix. no problem. mail is ok. A by-product of that, as bizarre as it may seem is this: As regular user, when I do 'su -' to become root, all is well. As regular user, when I do 'sudo bash' I become root alright but I also get: sendmail: fatal: Recipient addresses must be specified on the command line or via the -t option I tried many things ranging from temporarily swapping sendmail.postfix to messing around with /etc/profile and /etc/skel/* and many other things. How can I address the annoying message above? Thanks, Farid

system gets suspended automatically!
by Chandra 06 Feb '08

06 Feb '08

Hello! I am running CentOS-5 with latest kernel available by deault (2.6.23). I installed it on a Dell XPS machine having Intel Quad processors (4 parallel cpus). I use it to run a computational program and I need to keep the program running for 1-2 months continuously. I generally boot it in runlevel-3 with network ON without X and use ssh from another machine to connect and run the program using the "nohup" utility. However, the system automatically gets suspended (the computational program stops, ssh stops working, whole the OS seems to be freezing) after 4-5 hours. I have stopped the "acpid" daemon and boot the kernel with "acpi=off" option in "grub.conf" but no help. The kernel log ( /var/log/messages) doesn't show anything special. After the instant of suspension, kernel also stops logging into "/var/log/messages". Please help me out. I think there is a kernel problem. I have run programs for days and days continuously using FC5 (which had older kernel). I can't use FC5 or older version of CentOS because I need GCC-4.1.2+ to compile parallel OpenMP program. Thank you, Chandra

Hi, I had successfully installed CentOS 5.1 fully updated in old Fujitsu Primergy MS610 server. There was no problem except that during startup, I found many message saying "ohci_hcd 0000:00:0f.2: wakeup". Searched the internet and did what is written to avoid this to no avail. Anyone have ideas on how to resolve this? It seems that it was related to USB port which, I will not use anyway.

strategy/technology to backup 20TB or more user's data
by ankush grover 06 Feb '08

06 Feb '08

Hi Friends, I am currently using Samba on Centos 4.4 as a domain member of AD 2003 with each user having a quota of 2GB(no of users is around 2,000). Now the management wants to increase the quota to 10GB with this there will be more than 20TB of data to be backup weekly which will take lots of hours. Currently Veritas backup software is used to backup data on tapes. There is a concept of snapshots of Samba with LVM where snapshots of samba are taken at the given interval but so far haven't found any good article or how-to on that and also what is the experience of users using this technology and also what other technologies are being to handle TBs of data. Kindly let me know if you need any further inputs Thanks & Regards Ankush

python XML processing to turn a XML file into a structure?

Kickstart stops with dialog about which networking device - how to avoid
by Keith Christian 06 Feb '08

06 Feb '08

Using a kickstart file that stops with a curses dialog "You have multiple network devices on this system. Which one do you want to install through?" The machine being configured with PXEboot has two ethernet interfaces. What's missing from the network entries below? I'd like this install to proceed without asking which ethernet interface. PXE begins the install with DHCP, so Kickstart should already know which of eth0, eth1, etc. to use. Here is the ethernet line in the ks.cfg file: network --device eth0 --bootproto dhcp Any ideas appreciated. =======Keith

xloadimage in centos 5.1
by Jerry Geis 06 Feb '08

06 Feb '08

I have noticed that xloadimage rpm is not in centos 5.1 I use the command "xview -identity" to get the size of gifs, jpgs, and pngs. xview is part of the xloadimage package. The command "file filename" also reports sizes for gifs and pngs BUT not for jpgs. Is there an alternative command to use to report gif jpg and png sizes? I thought about just getting an older xloadimage package and that works but I want to do it the right way... THanks, Jerry

hp dl585 - qlogic hba's - centos 4.5 x86_64
by Tom Brown 06 Feb '08

06 Feb '08

Hi I recently installed some hba's into a bunch of these 585's as they are forming a RAC cluster - previously to this they were all using DAS without issue. After the qlogic cards were installed i reinstalled the OS and now once installed the OS will not boot - the box just reboots continuously, it does not even appear to get to grud, although this could be the ilo not displaying correctly. I have installed the OS onto the internal RAID set as usual and the MBA gets put onto this internal RAID disk also, the internal disks are just laid out in a /boot and a / Does anyone know what the issue could be or how i could disable these hba's during the install process so that they are not recognised? thanks

Removing a disc from a software mirror
by Joseph L. Casale 05 Feb '08

05 Feb '08

If I needed to remove a disc from a software mirror for a quick backup before a test, how can I remove it cleanly so that it has a good copy of the OS on it? If I use mdadm to fail then remove it, this would be done while CentOS is running (It's a mirror of the system disc) and I suspect the data on it would not be in a clean state? Is there a way to say have it not involved in the mirror after the next boot for instance? Thanks! jlc

Enterprise-class monitoring system for CentOS and Win2k3 server
by Sean Carolan 05 Feb '08

05 Feb '08

Can anyone recommend an enterprise-class monitoring system for both Linux and Windows servers? Here are my requirements: SNMP trap collection, ability to import custom MIBs isup/isdown monitoring of ports and daemons Server health monitors (CPU, Disk, Memory, etc) SLA reporting with nice graphs Pager/Email/SMS alerts with groups, filters and escalations Built-in MTBF and MTTR reporting Robust parent-child relationships between monitors or probes. For example, the system must be smart enough to know that if 25 URLs have gone down all at once, that they belong to an apache process that has died. I don't want 25 alerts, I want *one* alert telling me that the parent apache daemon is down. Ability to easily create dashboards from various monitors. We want this so we can see all components of a website in one place, eg, apache URL, database server, disk storage, etc. Attractive, easy to use GUI. We don't want a homebrew project with ugly graphs and a web 1.0 GUI. So far the products I have looked at are: NimBUS SolarWinds IP Monitor WhatsUPGold GroundWork Open Source Nagios And none of them have met all my requirements. Any suggestions?

Creating a Roaming imap account
by Anne Wilson 05 Feb '08

This (CentOS5.1) box is my new imap server. Using system-config-security-level I opened port 143 tcp, and mail is readable throughout the LAN. I want a Roaming account on my laptop so that I can read mail while away from home. I have set up the account in kmail, and I know that that part is correct, as it worked on my old, less-secured, imap server. However, I haven't been able so far to make a connection. Do I need 143 udp open? What else must I do to allow me to connect over WAN? Thanks Anne

I have a quick question. The board and CPU that I'm using in one of my machines was given to me. I didn't take the time to look up the info on the board or anything. I was busy, so I just put the board in a pc case, hooked everything up, and loaded the os on the machine. I didn't know it at the time, but there's a chance it may be a 64bit board and cpu. I don't want to pull the machine out of the desk, and open it up to find out. Is there a command entered by way of the terminal window that will tell me what kind of cpu I have? I want to say that it's an AMD sempron 3000+, but I'm not sure. Thanks Jim

If the system is frozen and you have to reboot the box to "unfreeze" it, I'd guess it's a heat issue. Cheers, Dave -- Politics, n.

Cluster fun

I've priced some 1 and 2U Dell servers. Now, I'd like to perform a price comparison of COTS hardware for 1 and 2U servers. What VAR companies do people recommend I check out for putting machines together? I'm perfectly capable of installing and swapping hardware components when/where needed, so on-sight support is not needed. Thanks much. Scott
