question on virtual desktops
by Jerry Geis 28 Jan '10

28 Jan '10

centos has the 4 virtual desktops by default. if I have a terminal window open in desktop 1 is there a command I can execute (type in) to switch to desktop 2? The mouse will not be attached at this point and I want to switch views using a command line. How do I do that? Thanks, Jerry

/usr/sbin/usermod -p doesn't update MAX_DAYS - workaround?
by Sean Carolan 28 Jan '10

28 Jan '10

I have a large group of Linux servers that I inherited from a previous administrator. Unfortunately there is no single sign-on configured so each server has it's own local accounts with local authentication. Normally I use ssh keys and a handy shell script to change passwords on all these machines with the usermod -p command. We are able to update the password on on one server and push the encrypted password out to all the others. If, however, we turn on password aging with "chage -M 90 username" then try to update passwords with usermod, the aging info for the account is not updated even though the password has been changed. Apparently this must be done manually for each and every server with the passwd command. This is not practical. In the long run we're going to try and get some kind of centralized authentication, but in the meantime does anyone have an idea for a workaround? Thanks Sean

Crash during yum update
by Kwan Lowe 28 Jan '10

28 Jan '10

Hello all: I was getting a reproducible crash during an update of a xen system. The problem went away after I set SELinux to permissive, but the fact that it crashed was alarming (first one on a non-dev system that I've had in over a year). I attempted the update earlier but it crashed at the same point after attempting to update selinux. After verifying hardware (all clean) I ran it again and crashed in the same location. Third time failed again in same location. I rebooted, changed selinux, then it completed after that. Unfortunately there are no dumps and I had to put the system back into operation. Didn't see anything in bugzilla either. Anyone else seen this? Here's the console output: Transaction Summary ================================================================================ Install 2 Package(s) Update 17 Package(s) Remove 2 Package(s) Total size: 56 M Is this ok [y/N]: y Downloading Packages: Running rpm_check_debug Running Transaction Test Finished Transaction Test Transaction Test Succeeded Running Transaction Updating : selinux-policy-targeted 1/38 general protection fault: 0000 [1] SMP last sysfs file: /hypervisor/uuid CPU 0 Modules linked in: autofs4 i2c_dev i2c_core hidp rfcomm l2cap bluetooth lockd sunrpc ip_conntrack_netbios_ns ipt_REJECT xt_state ip_conntrack nfnetlink iptable_filter ip_tables ip6t_REJECT xt_tcpudp ip6table_filter ip6_tables x_tables ipv6 xfrm_nalgo crypto_api dm_multipath scsi_dh scsi_mod parport_pc lp parport xennet pcspkr dm_raid45 dm_message dm_region_hash dm_mem_cache dm_snapshot dm_zero dm_mirror dm_log dm_mod xenblk ext3 jbd uhci_hcd ohci_hcd ehci_hcd Pid: 4269, comm: semodule Not tainted 2.6.18-164.10.1.el5xen #1 RIP: e030:[<ffffffff88037cb0>] [<ffffffff88037cb0>] :jbd:journal_grab_journal_head+0x25/0x44 RSP: e02b:ffff88001ee5fb50 EFLAGS: 00010202 RAX: 0000000000304027 RBX: ffff88001d78e370 RCX: 0000000000000035 RDX: fffd88001d7939d0 RSI: ffff88001d78e310 RDI: ffff88001d78e370 RBP: 0000000000000001 R08: ffffffff804f8e00 R09: ffff88003e513600 R10: ffff88001d793a30 R11: ffffffff8804fc33 R12: ffff88001d793a30 R13: ffff88003e513600 R14: ffff88000194d908 R15: 0000000000000001 FS: 00002b85be90abc0(0000) GS:ffffffff805ca000(0000) knlGS:0000000000000000 CS: e033 DS: 0000 ES: 0000 Process semodule (pid: 4269, threadinfo ffff88001ee5e000, task ffff880032883820) Stack: ffffffff88032257 0000000000000000 0000000000000000 ffff88001d78e3d0 00000c000194d8d0 ffff88001d78e2b0 ffff88000194d908 000000000000056e 0000000000000004 000000000000056e Call Trace: [<ffffffff88032257>] :jbd:journal_invalidatepage+0xdc/0x358 [<ffffffff8021d3dd>] truncate_complete_page+0x1b/0x5c [<ffffffff8022b98f>] truncate_inode_pages_range+0x9b/0x290 [<ffffffff802c555b>] vmtruncate+0x4e/0xc9 [<ffffffff8024335e>] inode_setattr+0x22/0x104 [<ffffffff88050b2f>] :ext3:ext3_setattr+0x1bd/0x228 [<ffffffff8022ceab>] notify_change+0x145/0x2f3 [<ffffffff802d17af>] do_truncate+0x5e/0x79 [<ffffffff80212f1a>] may_open+0x1d3/0x22f [<ffffffff8021b4ce>] open_namei+0x2c8/0x6ed [<ffffffff80227a14>] do_filp_open+0x1c/0x38 [<ffffffff8021a1b8>] do_sys_open+0x44/0xbe [<ffffffff802602f9>] tracesys+0xab/0xb6 Code: ff 42 08 8b 07 a9 00 00 20 00 75 0a 0f 0b 68 f5 97 03 88 c2 RIP [<ffffffff88037cb0>] :jbd:journal_grab_journal_head+0x25/0x44 RSP <ffff88001ee5fb50> <0>Kernel panic - not syncing: Fatal exception

Postfix 2.6.5 in CentOSplus?
by Dirk H. Schulz 27 Jan '10

27 Jan '10

Hi folks, according to several findings on the web I tried to find postfix-2.6.5 in centosplus adding this to my /etc/yum.repos.d/CentOS-Base.repo: [base] exclude=postfix [centosplus] includepkgs=postfix in the right places. But when I "yum remove" and "yum install" postfix then, it's "only" 2.3.3-2.1 with added mysql/pqsql support. Is there anything I am doing wrong? Or is there just no postfix 2.6.5 in centosplus? Dirk

need some help with compiling mod_gnutls
by Tobias Weisserth 27 Jan '10

27 Jan '10

Hi everybody, I want to build mod_gnutls. The problem: CentOS' version of GNUTLS is too old to link against, so I compiled and installed GNUTLS from source and put it into /opt where it doesn't hurt the already installed GNUTLS. Now I have trouble linking against this version as the autoconf buildchain in mod_gnutls does not find the newer version. I tried like this: ./configure -with-libgnutls=/opt/lib ./configure -with-libgnutls=/opt/bin I get this from configure: checking for libgnutls - version >= 2.4.0... no *** An old version of LIBGNUTLS (1.4.1) was found. *** You need a version of LIBGNUTLS newer than 2.4.0. The latest version of *** LIBGNUTLS is always available from ftp://gnutls.hellug.gr/pub/gnutls. *** *** If you have already installed a sufficiently new version, this error *** probably means that the wrong copy of the pkg-config shell script is *** being found. The easiest way to fix this is to remove the old version *** of LIBGNUTLS, but you can also set the PKG_CONFIG environment to point to the *** correct copy of pkg-config. (In this case, you will have to *** modify your LD_LIBRARY_PATH enviroment variable, or edit /etc/ld.so.conf *** so that the correct libraries are found at run-time)) configure: error: *** *** libgnutls was not found. You may want to get it from *** http://www.gnutls.org/ *** I don't understand this. I already set the PKG_CONFIG_PATH to /opt/lib/pkgconfig (according to pkg-config manpage) but that doesn't work. What's the easiest way to make mod_gnutls link against GNUTLS as installed in /opt/lib? thanks, Tobias W.

by Arvind P R 27 Jan '10

27 Jan '10

hi all can someone please guide me to a good howto to Generating X.509 Certificates in centos 5.4 with open ssl? i am using a windows based desktop virtualization software called vWorkspace which requires (copy/paste from vWorkspace documentation) • One or more X.509 web server certificates (depending upon configuration) • Trusted root certificate from the issuing CA installed into the Windows machine store of the SSL Gateway for certificates that have been installed on Web Access or Connection Broker servers. • Your certificate should have the same Issued To and Friendly Name. • The certificate should be an RSA (1024) certificate, not an AES certificate. • You should have a private key that corresponds to the certificate. i need the certificate for testing purposes only, so i m using openssl to generate a self signed certificate. i m not good enough with the concepts either. hence need sme help thanks in advance Arvind

md boot device
by Joseph L. Casale 27 Jan '10

27 Jan '10

The secondary disc was used in a lab rig to boot off of and test something after which the primary was replaced and the system was booted off of. It saw the secondary as more recent and dropped the primary so, the secondary was removed and the primary was used to boot. Figuring that made it more recent, even after it was restarted with the "now older" secondary, it still wants to drop the primary? W/o blowing out the secondary (it can't be hot added) how can I force the primary to not be dropped? I'm amused that even with it used to boot solo, and hence timestamps validating it as most recent, md will only use the secondary to start from? Thanks! jlc

DNS issue.. help ?!
by Roland Roland 26 Jan '10

26 Jan '10

Hi All, i have DNS configured on my centos 5.2 server. it's all working fine, right now i want to change the main public dns from one IP to another to do some testing (the new public dns ip has records which the old one doesnt have and it's done as such for testing) so i got into /etc/resolv.conf and changed the first nameserver to the NEW public DNS. /etc/init.d/network restart /etc/init.d/named restart when i issue an nslookup example.com ON the dns server, i get the exact IP i want to do testing on. but when i do nslookup example.com on the clients machine. the website resolves to another IP ( the one set in the initial public dns records) is there any other changes i need to do for the DNS server redirects its requests to the new public dns ?

Xen, Amazon, and /proc/cmdline
by Kurt Newman 26 Jan '10

26 Jan '10

Amazon (or perhaps Amazon's configuration of Xen) forces a machine to come up at run level 4, regardless of what's in /etc/inittab. I've looked through /etc/rc.sysinit and /etc/rc.d/rc, to determine which (if any script) looks at /proc/cmdline and forces a particular run level, but to no avail. It seems that /sbin/init does the forcing. Can anyone confirm that /sbin/init reads /proc/cmdline to overwrite /etc/inittab? I can't seem to find any reference in man pages or searching the web. Thanks, Kurt

Rolodex for linux
by David McGuffey 26 Jan '10

26 Jan '10

As I migrate away from Windows, I need to move the data out of my old rolodex program (written in Pascal back in the late 80's) into something that runs on Linux. The data is stored in csv lines in a text file. That old custom program output the data to rolodex cards on a pin-feed dot matrix printer. (Yea...I'm dating myself). Anyway, does anyone know of a decent rolodex program on linux that also has the capability of printing to the 3.5" wide rolodex cards? DaveM

The OP's problem lies not with the -exec construction but with the unstated, but nonetheless present, './' of his find invocation. Therefore he begins a recursive descent into that directory tree. Since the depth of that tree is not given us, nor its contents, we may only infer that there must be some number of files therein which are causing the MAXPAGES limit to be exceeded before the recursion returns. I deduce that he could provide the -prune option or the -maxdepth= 0 option to avoid this recursion instead. I have not tried either but I understand that one, or both, should work. -- *** E-Mail is NOT a SECURE channel *** James B.

autofs with nfs plus local directories
by Carlos Santana 26 Jan '10

26 Jan '10

Hi, I have a autofs configured to mount home dir from NFS. All user accounts lookup is done using LDAP. All is working fine with this setup. Now I need to create a local user account and have its home dir also on local system. So I added a new user account and changed auto.home as follows: test1 -rw,hard,intr /home/test1 * -rw,hard,intr nfs1:/export/users/& But this stuff is not working. If I change test1 user's home dir to '/opt/test1', it works fine. Log messages indicate: 'umount_autofs_indirect: ask umount returned busy /home'. I have some LDAP users logged on to system. Do I need to tell them to logout to successfully reload autofs? Any clues on this would be really helpful. Thanks, CS.

Kerberos integration in directory server
by nimmermehr＠chello.at 26 Jan '10

26 Jan '10

Hi, Got some issues regarding Kerberos and Directory Server and hope someone can help me out. Used these for the configiruation : http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-kerberos.html http://www.redhat.com/docs/manuals/dir-server/8.1/install/index.html Server : CentOS 5.4 with Kerberos and Directory Server installed Client : CentOS 5.4 I use putty to connect to the client, which authenticates against the server. Using Kerberos or LDAP worked perfectly (using system-config-authentication on the client for configuration) The only thing that doesn't seem to work is the kerberized version of the login via LDAP on the directory Server. Shouldn't I get a Kerberos ticket for that ? If I activate kerberos AND ldap in system-config-authentication it fails : Jan 25 13:24:59 monarch sshd[3947]: pam_unix(sshd:auth): check pass; user unknown Jan 25 13:24:59 monarch sshd[3947]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=192.168.0.1 Jan 25 13:24:59 monarch sshd[3947]: pam_succeed_if(sshd:auth): error retrieving information about user testuser Jan 25 13:25:01 monarch sshd[3947]: Failed password for invalid user testuser from 192.168.0.1 port 1142 ssh2 I followed the instructions here : http://directory.fedoraproject.org/wiki/Howto:Kerberos Maybe I just didn't get it ;) Thanks in advance, Peter

Detect file change
by Alan Hoffmeister 26 Jan '10

26 Jan '10

Hello everyone! How can I detect if a folder have changed (sync logic) than run a script if it's true? I found this script over the net, but I think it's such complicated for that simple thing... #!/bin/bash ############### detectdir.sh by Jagbir Singh ################# # # script to detect changes in directory. # ############################################################### # directory to watch DIR="/var/www/vhosts" # store current statistics of dir OLD=`stat -t $DIR` while true do # take a new snapshot of stats NEW=`stat -t $DIR` # compare it with old if [ "$NEW" != "$OLD" ]; then echo "changed!" ## you may want to comment this # take current listing of dir in a file. domains may be added or removed. ls $DIR --file-type | grep "\/" | sed 's/\///' > /tmp/dir.list # open file and you can now process entries in it exec 10 let count=0 while read LINE <&10; do # currently printed on screen, can supply this as arg to rSync, discussed later echo $LINE/httpdocs/ echo ((count++)) done # take snapshot again and store it in both old and new vars NEW=`stat -t $DIR` OLD=$NEW exec 10>&- fi # i'm using 3 secs calm time, you should update this as per your environment sleep 3 done

any significant differences between centos and OEL?
by Robert P. J. Day 26 Jan '10

26 Jan '10

someone just pointed out to me that there is a distro called "oracle enterprise linux" which is effectively a re-branded RHEL, so i'm curious -- has anyone here used both centos and OEL and would there be any differences that would be worth caring about? the only thing i can think of that might be worthwhile is that OEL might change some of the default kernel parms thru /etc/sysctl.conf that make that distro more appropriate for running large oracle databases. beyond that, i have no idea. thoughts? rday -- ======================================================================== Robert P.

Firewire issues with CentOS/RH?

I read in another forum that CentOS has problems with Firewire drives, something along the lines of whenever a new kernel is booted, the drives are gone. Can anyone elaborate on that? I don't use Firewire drives (at all, yet), but information about this would be nice to have.... Thanks. mhr

The man page does not say that find acts upon each file as it is found, only that it acts upon each file that is found. Neither does the man page speak to the limits of the kernel configuration (MAX_ARG_PAGES) implicitly used by cp, find, ls, etc. The problem you have is that the selection of all qualified files is completed before any are acted on by find. So, in your case of an overlarge collection, the page limit is exceeded before any are deleted. Taking each file as it is found and piping it to an external rm command explicitly defines the process as find, delete and find again, and thereby avoids hitting the page limit. CentOS-5.3 was supposed to address this issue: > Previously, the MAX_ARG_PAGES limit that is set in the kernel > was too low, and may have resulted in the following error: > > execve: Argument list too long > > In this update, this limit has been increased to 25 percent of > the stack size, which resolves this issue. So, perhaps if you update to 5.3+ the problem might go away? Although, in my opinion, piping find results through xargs is far more reliable and portable.

Automatically check into SVN?

These files are configuration files, and it would be good to be able to revert back by simply checking out the older versions. But I would to check in the files every files minutes, and I'm sure SVN will not use up any disc space, unless there are any changes.

streamripper & CentOS?

25 Jan '10

I am trying to build streamripper from source, I don't see rpms available for it. I have all the parts of yum groupinstall 'Development Tools' in place. rpm shows that a 2.5.* is in use # rpm -q glibc glibc-2.5-42.el5_4.3 Any attempt do get past the ./configure for streamripper fails checking for GLIB - version >= 2.16.0... no *** Could not run GLIB test program, checking why... *** The test program failed to compile or link. See the file config.log for the *** exact error that occured. This usually means GLIB is incorrectly installed. configure: error: Glib 2.16 or greater required After a lot of googling, I see some people on Ubuntu seem to have been missing a glibc-dev: http://sourceforge.net/projects/streamripper/forums/forum/19083/topic/34574… but I don't see that available for me to pull from yum, and trying variants via: [root@localhost streamripper-1.64.6]# yum provides */libglib* does not pull up what I seem to need here either. I feel I must be missing some path, but I cannot find it. I built this fine on my BSD machines, and this app is part of the available install base for e.g. Ununtu and FreeBSD etc-- it is not as if this is esoteric. Does this not build under CentOS? or am I missing something really straightforward. I searched the forums via google and find really no one talking about this, so either I'm missing some path or something obvious, despite looking, or it's just kown/assumed to not work.

After reading docs and trying various things I've reduced the source of the problem to the package gstreamer-plugins-ugly-0.10.11-1.el5.rf.i386.rpm # rpm --rebuilddb # rpm -q libdvdread libdvdread-4.1.3-1.el5 # rpm -i gstreamer-plugins-ugly-0.10.11-1.el5.rf.i386.rpm error: Failed dependencies: libdvdread.so.3 is needed by gstreamer-plugins-ugly-0.10.11-1.el5.rf.i386 And, after erasing libdvdread and trying to install both packages in one command, I get pretty much the same contradictory error message: # rpm -iv libdvdread-4.1.3-1.el5.i386.rpm gstreamer-plugins-ugly-0.10.11-1.el5.rf.i386.rpm error: Failed dependencies: libdvdread.so.3 is needed by gstreamer-plugins-ugly-0.10.11-1.el5.rf.i386 There's no problem installing libdvdread by itself: # rpm -iv libdvdread-4.1.3-1.el5.i386.rpm Preparing packages for installation... libdvdread-4.1.3-1.el5 # rpm -q libdvdread libdvdread-4.1.3-1.el5 So how are people getting totem to play movies? tia. -- Without music, life would be a mistake. --Friedrich Nietzsche

Centos 5.2 mysql build
by Rajagopal Swaminathan 24 Jan '10

24 Jan '10

Greetings, I wanted to enable blackhole and CSV engine in the mysql server so downloaded the SRPM from Centos Site, setup the rpmbuild envronment with mighty help from the our own Russ's Owlriver website and tried building it. I have a 5.2 centos box on which I need to enable this so took the 5.2 SRPM (mysql-5.0.45-7.el5.src.rpm) from vault.centos.org.(mysql The Build did not complete throwing errors during testing about unable to connect using ssl or something. I tried from 5.4 SRPM at least the build went thru. Was 5.0.45 srpm broken? or did I get it horribly wrong somewhere as it is my first attempt to build from srpm. Now I have a situation wherein the PHDs refuse to work with the Mysql 5.0.77 (y'know those typical silly scared rabbits who will never move from status quo no matter what) I fished around and found that there was a BIG thread on this issue. I understand it is a upstream issue. But in the EOD, I need a tested stuff not homegrown one (according to the PHDs and I am new in this job, never mind I will be completing 26 years in IT field on 3rd Feb...). Has anybody come across this error? if so how it was mitigated? The issue here is we need to show it working on centos and then when going live the production will be switched over to RHEL (Sorry Centos guys... That's the way this Indian (1/6th) part of the world goes about: kinda "successful POC first and then I give hard cash"). Thanks and Regards, Rajagopal

There is two disadwantages with it: first, it's quite untrivial task to get it working under Centos, and second, it doesn't work anymore :) >From official fuse-gmailfs site (richard.jones.name): Gmail Filesystem no longer works with the latest Gmail interface, and will not be maintained in the future. BTW, according to google EULA, it's illegal to use gmail it that way. Gmail team could even disable you account. I would suggest you to take a look at dropbox, which provides 2-5Gb online storage with full desktop integration on lin/win/mac. At the moment it's quite tricky to install in under CentOS, because it uses python 2.5 (CentOS has python 2.4), but it's achievable: http://wiki.dropbox.com/TipsAndTricks/CnetOS-KDE-Install . Fancy GUI isn't working at the moment. I'm currently backporting it to CentOS, and I would like to include it in rpmforge (it's distributable). I estimate it in about one week. I hope it'll be useful ... Nikita

Question about running a CentOS4.8 (32-bit) guest under CentOS5.4xen (64-bit)

I am trying to run my old CentOS4.8 (32-bit) system as a guest system under CentOS5.4xen (64-bit).

Git: help sought
by Timothy Murphy 23 Jan '10

23 Jan '10

I have a project using Git on machine A. I'm running a Centos server on machine B. I'd like to "publish" the project on machine B (mainly for my own use, so I can access it from various sites). I've asked about this on a Git mailing list, but haven't understood the replies. In particular, a couple of people suggested gitolite, but when I examined this I couldn't make out what it did. As will be obvious I am a Git newbie, having been reared on SVN. But I thought some CentOS users might have met this problem and come to a simple solution. -- 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
