Cleaning Up My Process Table
by Michael B Allen 14 Jun '06

14 Jun '06

I'm upgrading my primary server from RH 7.2 to CentOS-4.3.ServerCD. I REALLY like the ServerCD. Who needs all the fluff that comes with a standard distro? If I want a system-config-gooey I can run Xnest [1] and ssh -X from my laptop. Anyway I have two questions: 1) How can I collectively stop all the NFS, portmap, whatever? I'm hoping it can be manipulated as a group because occationally I actually will want to use NFS. 2) Can I safely turn off dbus, hal, and/or xfs? Or will something really bad happen if I try to run the system-config-gooey's without them? Thanks, Mike [1] Although I haven't managed to figure out how to run it without -ac.

Has anyone already worked out the files involved in changing from the rather pedestrian screensaver to some more pleasing eye candy like Fedora Core 5 uses? thnx/ldv

Simple backup program
by Bowie Bailey 14 Jun '06

14 Jun '06

I am looking for a simple backup program that I can use to backup a CentOS box to a local tape drive. Hopefully someone here can give me a recommendation. This is what I need: - Simple launching of manual backups (preferably from the command line) - Ability to span tapes for a large backup - Proper treatment of hardlinked files - Notification via email or similar when it is ready for the next tape. I tried mondo-rescue, but decided against it after it spent 4 hours just trying to index the files (it never actually started the backup). I am considering Amanda, but the setup is a bit complex and, based on the docs, the tape spanning capability isn't the best. Anyone have any suggestions? I would think that there would be a simple program out there to backup and restore from tape without all of the extra scheduling and indexing features. -- Bowie

SSL fingerpring mismatch and issuer certificate problem
by M. Fioretti 13 Jun '06

13 Jun '06

I have a remote server running centos 4.3 and a home desktop running suse 10.1. I have generated an SSL certificate on the server, copied it on the desktop and run on the desktop: >openssl x509 -in mynewcertCert.pem -fingerprint -subject -issuer -serial -hash -noout >c_rehash . getting this warning: > > Doing . > WARNING: mynewcertPrivateKey.pem does not contain a certificate or CRL: skipping > mynewcertCert.pem => 2764d17c.0 Now I have noted two things: 1) the fingerprint generated from the openssl command above is different when I run it on centos or on suse 10.1. Why? 2) if I run fetchmail here with these options: I get: fetchmail: 6.3.2 querying my.remote.server (protocol POP3) at Tue 13 Jun 2006 07:22:34 PM CEST: poll started fetchmail: Issuer Organization: The M Zone fetchmail: Issuer CommonName: my.remote.server fetchmail: Server CommonName: my.remote.server fetchmail: my.remote.server key fingerprint: the one obtained running openssl on the server fetchmail: my.remote.server fingerprints match. fetchmail: Server certificate verification error: unable to get local issuer certificate 26227:error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed:s3_clnt.c:894: fetchmail: SSL connection failed. fetchmail: socket error while fetching from m-mail(a)fm.vm.bytemark.co.uk What is the "local issuer" problem? What am I missing? Is it a consequence of problem 1) ? What is happening, and what must I do to use this certificate?

Restoring data from disk w/ messed up partition tables
by techlists＠comcast.net 13 Jun '06

13 Jun '06

I had the electricity go out the other day. When my Centos 4.3 workstation came up, I said yes when it got to the prompt "Unclean shutdown, force filesystem check?" prompt. It ground away for awhile and then said something about a bad superblock. Yikes! I thought, that's a bad sign. After a reboot, I got nothing but a grub> prompt. I tried booting into rescue mode using the install CD, and got a message "No valid partitions found". I tried to mount /dev/hda, and got a message "no /etc/fstab found". I tried running the install CD, and went into Disk Druid to see if it could see any existing partitions on the drive, and got the message "Partition table corrupted, must re-initialize disk, and reformat". Not a good sign. I backed out at that point, not wanting to go beyond a point of no return. I have about 4 years of archived e-mails, and some other misc stuff on that drive that I don't want to lose. Anyone have any suggestions what steps to take next? Paul

Any plans to update kernel-utils for newer smartmontools
by rik＠harddata.com 13 Jun '06

13 Jun '06

I have SATA drives and have found that the newest smartmontools package will retrieve smart data from SATA drives with the '-d ata' switch. Is there a devel/testing package of kernel-utils available or should I just roll my own? Rik

Changing from dynamic ip to static ip
by Thomas E Dukes 13 Jun '06

13 Jun '06

Hello, I have been on a dynamic ip for about 5 years and have just upgraded to a static ip. I know I need to change my network setup on my eth0 nic to static and stop ddclient from trying to update my address but is there _really_ anything else I need to change. I have a couple of websites on this address using *:80 in my httpd.conf. I can easily change this but don't think it would really make any difference if I don't. Also, my ISP is using different lingo than what linux uses. I suspect they think everyone runs Windoze. Can anyone decipher this for me, my ISP tech support has already gone for the day. IP Addresses: 71.30.117.0/30 Netmask: 255.255.255.252 Router IP: 71.30.117.1 <--------------- This Useable IP's: 71.30.117.2 <--------------- and this My ip address, if I do an ifconfig, is 71.30.117.1. This has me a little confused as they tell me my ip address is 71.30.117.2 TIA

Help debugging superodoctor
by Sam Drinkard 13 Jun '06

13 Jun '06

I've tried several times to get superOdoctor to run on this machine, and have had no luck yet. Aside from this error message, # superodoctor ***************************************************************************** Supero Doctor II - Linux version 2.24(060523) Copyright(c) 1993-2006 by Super Micro Computer, Inc. http://supermicro.com/ ***************************************************************************** (superodoctor:7713): GnomeUI-WARNING **: While connecting to session manager: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed. The application appears to open, then just crashes, never producing any output or anything. I've included a backtrace, just in case someone could help me out. The thing that worries me is the lib64/tls/libpthread.so.0. That same library gave me problems when I was setting up the WRF weather model to run, and was forced to use LD_ASSUME_KERNEL = 2.4 in order to get it to run. I tried the same trick with superodoctor, but did not work. Any and all help appreciated... I've sent requests for help to super micro, but have not gotten any response from them. This is an x86_64 machine, and the version of superodoctor is for the x86_64. AFIK, the installation was OK, with no problems.

SSL: Server CommonName mismatch: localhost.localdomain
by M. Fioretti 13 Jun '06

13 Jun '06

Greetings, I have seen via google that this very problem was already discussed on several lists some months ago, but the archives report no solution. I have a remote server with dovecot 1.0-0_12.beta8 on Centos 4.3. IMAP works just fine: I can read email from both Squirrelmail via web and Kmail. Now I have created an ssl certificate on the server, and I'm trying to retrieve email via pop3s from my home PC (running suse, if this matters) When I launch fetchmail here at home I get the error below. Is it caused by dovecot, or something else on the server, like some error I could have made when generating and copying certificates?
