Upgrading from RH 9
by Zyxian 08 Sep '06

08 Sep '06

Howdy. I've got a RH 9 server that has a 60 gig hard drive in it. I'm gonna replace it with a 100 gig and install CentOS 4.4. Can I just copy the password files, home directories, config files, etc. or does it need to be done some other way? Thanks

I like to keep my mails, additional to my privat I am following several mailing list, separated, so the quota is way to small. I feel like the best for me is to move my domain here, setting up my own server. I have been using djbdn and qmail earlier, but would like to change to something more standard, I should manage though, but I am a little afraid of the work load setting things up. So my question at the moment boils down to, witch supplier of dynamic dns service to use, that also mx forward without to many restrictions. Thanks Kai

DAR - Disk ARchive packaged for CentOS?
by J.J. Garcia 07 Sep '06

07 Sep '06

Hi folks, I was searching for a backup tool simple and easy to use from command line to backup on DVD certain disks, even the whole OS. I was using mondoarchive almost succesfully but recently found what i think i was needing, it's called DAR (http://dar.linux.free.fr/) - i think im not the first that uses it - anyway, after searching for it already packaged for CentOS/RHEL/Fedora, i didn't find it. It's already packaged for debian, madrake, openSuSe, etc.. but i think there's not a pkg for RHEL systems. If somebody knows where i can find it i would appreciate it, or even if it's possible to include it in CentosPlus repo, TIA Jose.

Radeon 9000 breaks with CentOS 4.4
by Barry Brimer 07 Sep '06

07 Sep '06

Dell Inspiron 600M w/ Radeon 9000 card. This worked with CentOS 4.3, also works with Knoppix 4.0.2. Graphical installation succeeds, but upon reboot, and all subsequent rebbots, graphical mode does not work, the screen becomes black. In addition to the 2.6.9-42 kernel, we have also tried the 2.6.9-42.0.2 kernel. Same problem exists on both kernel. Running system-config-display --reconfig exits with the error "fatal IO error 104" Connection reset by peer. Any ideas would be greatly appreciated. Thanks, Barry

Kernel ELsmp vs EL
by Sebastien Tremblay 07 Sep '06

07 Sep '06

Hi all, I'm not very used to CentOS and Linux generally speaking, though I read a lot and 'man' quickly became a very good friend of mine, right after Google, so sorry if that's a ridiculous one! (at least it'll give you a good laugh!) I updated the kernel to 2.6.9-42.0.2 recently and that raised a question... Simple... Yet silly...! What exactly is the difference between 2.6.9-42.0.2EL and 2.6.9-42.0.2ELsmp? It seems the default install was the 'smp' kernel, but as I had to change the grub config I stumbled across this one and... started wondering...

Ctl+Alt+F12
by Ted Miller 07 Sep '06

07 Sep '06

I am migrating from Mandriva to Centos (currently running dual boot). One thing I miss on Centos is being able to switch to Console 12 and see system messages in real time. My IPCop firewall has this turned on as well. Is this a setting I can change, or a program I can add, or is it not available? Ted Miller

New mailing list and wiki contribution
by Ralph Angenendt 06 Sep '06

06 Sep '06

Have some Tips and Tricks for doing stuff the easy (and right) way? Ever wanted to do that writeup of what you achieved with spec files? What about that news server howto in the upper drawer of your desk? That apache tuning paper on your computer? Your shortcut collection for Gnome? Or whatever might help people with using CentOS? This is your chance: We're looking for contributors to the CentOS wiki, for people who want to spread their knowledge to other users, for people who actually like writing documentation. Want to do it? It's easy. Head over to <http://wiki.centos.org/>. Find out where *your* contribution fits best. Create a Login on that page with a username in the format FirstnameLastname. Then subscribe to the centos-docs mailing list at <http://lists.centos.org/mailman/listinfo/centos-docs>. After going through the subscription stuff write a mail to centos-docs(a)centos.org in which you describe *what* you want to put *where* on the wiki. If you know which name that page should get - that's even better. Someone of the Wiki Admins will then create that page for you and give you edit permissions. Et voilà - you can create your page. Once you have contributed more than a little content and have shown a desire to keep it up(dated), we'll open up edit permissions for you. Okay, I lied. It's not really easy. Believe us, we would like to have an open wiki where everyone can edit pages by just creating a login and then going ahead. But it's not possible for us to scan the wiki for changes all the time. Say thanks to the spammers who "contribute" everywhere they are able to. About the mailing list: It's not only for contributing to the wiki, but also for discussing about articles (i.e. article quality) on the wiki - and possibly also for discussion about general CentOS documentation. We'll see. See <http://wiki.centos.org/HowToContribute> for more information. Thanks for letting me interrupt your reading of other fine mails on this list.

postfix pb with mass emails
by sophana 06 Sep '06

06 Sep '06

Hi I'm hosting a forum (phpbb) with more than 3500 users with centos 4.3. The forum admins would like to send an email to its (3500) users. I configured phpbb to use smtp (postfix-2.1.5-4.2.RHEL4.mysql.centos4) to send the email. I raised the max destination limit from 1000 to 5000, and made a test. Here the disaster began: Majority of the users received from 20 to 50 emails. Looking at the logs, postfix divided the email into several ones with 50 recipient each (as documented). I think the problem was that when one of the recipients was unreachable, the mail went into defered state, to be retried later. The problem (bug?) is that the mail was sent again to all 50 recipients, explaining why so many users received lot of mails. Anyone had a similar problem? Any suggestion for that? Regards Sophana

How to find differences in Centos Builds
by Andrew Elliott 06 Sep '06

06 Sep '06

Good Afternoon, Long story short I recently upgraded my CentOS 4.4 from: 2.6.9-34.0.2.EL to 2.6.9-42.0.2.EL and am having problems with dhcp, dns and ftp (very funky nat setup, don't ask). My question is: What is the best way of troubleshooting issues after upgrading? Is there a list of changes between versions that I can look at somewhere? (obviously, but where?) I've already done a diff between kernel variables(net.ipv4.*) and found some differences. I've also taken a look at which packages yum has updated in the process. Am I going to have to go through changelogs for each package to find out what I'm looking for? There are no kernel panics, no obvious errors and all services appear to start fine.... Thanks in advance. Andrew Elliott.

new Centos 4.4 install--display update very SLOW
by fredex 06 Sep '06

06 Sep '06

Hi! I just installed Centos 4.4 on a machine at work, yesterday. Mostly it went well with just a couple of glitches. One of them is slow video performance. No, I'm not playing 3d games at work! :) Scrolling/repainting terminal windows is plainly MUCH slower than it is on my Centos 4.4 desktop at home. Machine at home is an Athlon XP 2600+ with one gig of RAM. Machine at work is a P4 2.26 Ghz with a gig of RAM. Before Centos, the one at work had RHEL WS 2.1, which did not exhibit the same issue. It was using KDE as the main desktop, while this time it is (so far) set to use Gnome (as is the box at home). Scrolling through a big file with less, for example, you can watch it paint the screen. Hitting 'B' to go back a screen is almost painful, you see it scroll part of the screen down, slowly, then fill in each line above that. It's the same hardware that was there before, the only thing that has changed is the OS. Clues? Thanks! -- ---- Fred Smith -- fredex(a)fcshome.stoneham.ma.us ----------------------------- The eyes of the Lord are everywhere, keeping watch on the wicked and the good. ----------------------------- Proverbs 15:3 (niv) -----------------------------

centos minimal install???
by Email Lists 06 Sep '06

06 Sep '06

I was doing an Internet facing server reload for a client today and he mentioned that there is a minimal install selection somewhere and that I should take a disk 1 of centos 4.4 and it would be under custom Is this the case? How? I couldn't find it, nor could he after the fact. If it exists, where is it, or how do I get to it for future reference please? I usually use a centos server cd myself. :-) Thanks and kind regards! - rh -- Robert - Abba Communications Computer & Internet Services (509) 624-7159 - www.abbacomm.net

Server closing all the ports after inactivity Could not connect to webserver
by Anil 06 Sep '06

06 Sep '06

Hi All I am running Centos -4.4 final with all the updates My webserver stop responding after about half an hour od inactivity.I just gets a timeout message. When I try to refresh the page 3-4 times it start active again. Infact all the ports on the server are closed during the inactive period even though I have ssh,ftp and http enabled on it. When the server is responding I can see (with a port scan)the ports are open. I tried disabling the firewall(on the centos server) altogether because the server sits behind another firewall.

OT - backup question/advice
by Thomas E Dukes 06 Sep '06

06 Sep '06

Hello, I have been using mondorescue to backup to dvd for several months now without any problems. Since upgrading to Centos 4.4, I now receive a few errors. The errors are for files in /var/named/chroot/proc. I guess these files change so when I do a differntial backup they aren't there and result in errors. (Never got any errors before and I think these files were there in 4.3) If I exclude the files from the backup, no errors. My question is what, if any problems would I run into not backing these files up and having to do a complete system restore? TIA, Eddie

Bug: lvchange delayed until re-boot. System lock up experienced.
by William L. Maltby 06 Sep '06

06 Sep '06

Did a search for LVM at the CentOS bugzilla. Nothing seems to match this scenario. If no one contradicts me, I'll also post this in the bug reporting system. Wanted to a) get confirmation, if possible before bugging it and b) warn other souls that may be adventurous too! Summary: failings in LVM and kernel(?) seem to make a "freeze" possible. 1) Lvchange --permission=r seems to not take effect until re-boot even though lvdisplay says it has taken effect; 2) Prior to reboot, mount will mount a read-only LV and give no warning that it is read-only and will mount it r/w. The opposite also occurs: if the LV was ro and it is changed to r/w, mount still acts as if read-only is in effect. 3) If these steps are done, *ALL* commands work as if everything is normal *except* "ro" seems to have no effect: - lvchange --permission=r # Seems OK - lvdisplay # Seems OK, says "r" - mount <normal mount args> # Only "t -ext2" extra, no "read # only" warning from mount command - >/mnt/the_mount_point/test # Seems OK, ls shows it - rm /mnt/the_mount_point/test # Seems OK, ls doesn't show it What would happen if I did not umount it here? I guess it would run for at least some time without problem. Then, if LVM truly has it ro, when buffer flush time came there should be some undesirable results. At this point, I issued a umount for the volume and the system froze with blinking keyboard LED. Subsequent re-boot and investigation added the knowledge that the change in lv status was delayed until reboot. Can/will anyone confirm/deny this for me? Thx. Node: Athalon, CentOS-4.3. fully updated, all normal components from base (wine and a few odds and ends from rpmforge). ============ Gory Details Below ====================================== Progressing on LVM education and simplified b/u procedure using it. Covered my butt by setting the lv to read only. Got the hare-brained idea to see what would happen if... >>:-( # Protect fools from themselves. # umount /dev/VolGroupAA/lvol1 # lvchange --permission r VolGroupAA/lvol1 Logical volume "lvol1" changed # lvdisplay VolGroupAA/lvol1 # Edited below to items of interest --- Logical volume --- LV Name /dev/VolGroupAA/lvol1 VG Name VolGroupAA LV Write Access read only LV Status available # open 0 LV Size 9.31 GB Current LE 298 Block device 253:3 # Notice: no read-only this mount & no warning from mount command # mount -t ext2 /dev/VolGroupAA/lvol1 /mnt/VolGroupAA_lvol1 # > /mnt/VolGroupAA_lvol1/test # ls show file created # rm /mnt/VolGroupAA_lvol1/test # ls shows file gone # umount /dev/VolGroupAA/lvol1 # Instant petrification! Purgatory entered: flashing keyboard LED and the usual three-fingered salute and destructive pounding on attached peripherals had the expected results! NADA! Googled here (it wrapped, sorry) http://groups.google.com/groups/search?hl=en&lr=&q=read-only+mount +write+LVM2+kernel+2.6+2006+lock+OR+crash&qt_s=Search Didn't see anything that looks like it. Saw a drbd related elsewhere that might come close... but NOPE! Anyway, since it seems (according to the HOWTO) that only mailing list activities report and address bugs (didn't see a bugzilla: did I look too casually?) I would like to confirm this is not peculiar to my node. I prefer not to subscribe to another list just to belatedly discover nothing of value after searching their archives too! If anyone else has a test machine and time, I will take the trouble to report this if it is confirmed. Subsequent reboot and test from the console gave this surprise. # lvchange --permission rw VolGroupAA/lvol1 Logical volume "lvol1" changed # mount -t ext2 /dev/VolGroupAA/lvol1 /mnt/VolGroupAA_lvol1 mount: block device /dev/VolGroupAA/lvol1 is write-protected, mounting read-only # There I realized that the status change was not propagated to the system until a re-boot. Later I tried adding a "lvchange --refresh" although the docs didn't seem promising. It had no effect. Confiming again, re-booted and did this.

very new user having problems
by barbaara fberg 06 Sep '06

I just loaded CentOS and want to connect to the internet using a radio and wireless internet. I got some numbers from the internet provider. He walked me through some of the changes in the networking area. But it did not work. I have read three books on Unix and I am determined to do this. but I think I need lots of help. Where could I look this up on a windows machine?? when I get connected to the net, then I have another question about how to make the jave download operational. thank you

DNS resolve.conf not working
by Ed Morrison 05 Sep '06

05 Sep '06

Hi All: After upgrading to 4.4 my server(s) will not resolve using the servers listed in resolve.conf. This is not true of a server running a DNS Cache server. I can do a netstat -e and show a connection to the DNS servers but it will not resolve any domain names (please see below). Any thoughts? [root@ftp ~]# dig yahoo.com ; <<>> DiG 9.2.4 <<>> yahoo.com ;; global options: printcmd ;; connection timed out; no servers could be reached [root@ftp ~]# netstat -e Active Internet connections (w/o servers) Proto Recv-Q Send-Q Local Address Foreign Address State User Inode tcp 0 0 10.0.2.5:32806 66.81.0.251:domain ESTABLISHED root 17584 Thanks, Ed

futex hang workaround by rebooting first (?)
by Zube 05 Sep '06

05 Sep '06

The previously noted upgrade-to-4.4 recipe: yum update yum sqlite python-sqlite ; yum update worked more consistently than running "yum upgrade," but it too fell victim to the futex hang. In my limited testing, a reboot of the machine before starting the upgrade gave me a 100% success rate. Given two identical machines, one that had been used for a few days and one that was freshly rebooted, the former would exhibit a futex hang, while the latter updated just fine. Cheers, Zube

Another odd postfix issue related to 4.4 update
by chrism＠imntv.com 05 Sep '06

05 Sep '06

Postfix appears to be running normally and is accepting/receiving mail as usual, but... I'm seeing lines like this in the message log: Sep 1 06:55:23 fender postfix/smtpd[11969]: sql_select option missing Sep 1 06:55:23 fender postfix/smtpd[11969]: auxpropfunc error no mechanism available Those seem to be sasl related, right? I'm not using sasl support (yet). Any clues to this behaviour would be much appreciated. Cheers, Chris

mozilla and seamonkey not the same
by Jerry Geis 05 Sep '06

05 Sep '06

I have searched the bugzilla and seamonkey has bugs when using "-remote openurl(www.google.com)" it always opens a new window. Mozilla did not have this problem. How can I continue to use the old mozilla? Both for system updates and for new 4.4 installs. I need the -remote functionality to not open new windows. Thanks, Jerry

My 4.4 upgrades
by Robert Moskowitz 05 Sep '06

05 Sep '06

My update method on two critical systems has been to use yumex. I select all, unselect major apps that I recognize (bind, openssh, etc), update and reboot. The yumex to get those apps and another reboot (most likely not needed). I have updated my notebook. The only detected problems are: madwifi drivers and lost Thunderbird icons in drawers (just had to go through the properties and reselect the icon). Too soon to tell about anything deeper.... One server so far. This is a new box that I built only a couple weeks ago. Update went fine. I am now taring up the system as a checkpoint before proceeding. Two Trixboxes. I am having that classic Trixbox problem with Centos and Zaptel, so I have to reread the docs, as yum update fails with unresolved dependencies. So after some fear and doubt, I have made the leap!

problems copying distro files
by Robert Moskowitz 05 Sep '06

05 Sep '06

At this point in my lab, the only solid servers I have are Win2000. So I xcopy the distro CDs into a directory that I make available for install via ftp. Well I have had problems copying files from this distro. I had to use the /c option in xcopy to get past the problem files.. A few examples are: The following files in the image directory of disk 1 has 'File creation error - The parameter is incorrect.": README boot.iso diskboot.img pxeboot/README My screen buffer is only 400, so I missed any errors in the first 1500 files. And I think there was one earlier (the reason why I had to add the /c option). On I think CD 3 in the Centos/RPMS the file tix.8.1.4-98.i386.rpm had a 'File creation error -Date error (cyclic redundancy check). I created both CDs twice from the ISO images, getting these errors. There may be others. Any input on this?

Yam not generating repomd.xml
by Eduardo Grosclaude 05 Sep '06

05 Sep '06

I think I have obeyed the docs. Metadata in yam conf says repomd (formerly createrepo but led to "unexisting --update option" message). Conf is otherwise pretty close to examples. I have downloaded Centos 4.4 ISOs, I have done yam -gv, ISO files are correctly mounted and published via HTTP, etc but no xml files are generated anywhere under /var/www/yam. What am I overlooking? Can I have yam make repo metadata if I have ISO files as well?

Removed Plus kernel, yum still wants to update plus kernel
by Robert Moskowitz 05 Sep '06

05 Sep '06

I am trying to get off the plus kernel. Hasn't helped yet, and my MadWifi does not work with it. So I used YUMEX to remove all of the plus kernel cruft that I could see. I rebooted. ONly the standard kernel was listed in the boot menu (good sign). Start up Yumex, and it is showing that the plus kernel needs updating. Nothing on the regular kernel. Just yum update behaves the same. So where does yum keep its 'memory', so I can remove references to the plus kernel and get back to the regular kernel?????

OT: How to make files placed into FTP directory available via http
by Ed Morrison 05 Sep '06

05 Sep '06

I'm hoping someone out there can tell me or direct me on where to find this info on how to make files placed into an ftp directory available via an url link in an email. I will have a staff member upload the files to a directory on my ftp server (which is also the web server) and the files would have to be automatically linked to a web directory, unless the files can be read directly from the ftp server. This needs to have no interaction from me and should be automagic..... Any and all would be greatly appreciated. Thanks Ed
