FC4 x86_64 system crashes every 7 days
by Jurgen Kramer 30 Jan '06

30 Jan '06

It seems that my server always crashes after 7 days and some odd hours. When I find it crashed the harddisk light is always on continuously. The problem is that this system does not have a monitor on it so I cannot see what the cause of is. Any ideas how to determine what the problem is? Dmesg does not reveal any clues. System specs: Asus A8N-E running FC4 x86_64 (fully updated) 1x SATA disk for system and swap 2x SATA in software RAID-1 Jurgen

bonjour, Is there a version of dvdbackup working under FC4. I installed dries version but it doesn't work: dvdbackup: symbol lookup error: dvdbackup: undefined symbol: UDFFindFile It seems that FC4 version of libdvdread does not export that symbol.... Who knows? Thanks. -- François Patte UFR de mathématiques et informatique Université René Descartes http://www.math-info.univ-paris5.fr/~patte

Re: FC4 bus error message at boot time

>>You should have a line like this in /etc/passwd >>named:x:25:25:Named:/var/named:/sbin/nologin >>if not, stick it in and the error might go away. Thanks. That did it. However. Why is "named" required to be there since I'm not running Bind?t Bind was installed by default. However, since this is a workstation, I uninstalled Bind using RPM -e. It seems that that left some junk around. >Does the Original Poster have that installed? Does he have >caching-nameserver, NetworkManager, or anything else that depends on it? No, none of them, as explained above. >If bind isn't installed, I'd recommend doing a yum install bind Why should I do it, since I'm not interested in having it? >If the Original Poster didn't have bind installed, and hadn't tried >installing any RPM's with --force, and hasn't mucked about manually, >*and* has all the latest updates installed, this probably ought to go >into bugzilla. I have not installed anything with RPM --force or modified any settings manually. I keep the system updated with Yum. Can I erase that line "named:x:25:25:Named:/var/named:/sbin/nologin" in /etc/passwd if I delete the line for named in /etc/shadow? Thanks, EGCP

This would require forcing the cluster to basically be on a separate subnet and have separate access to the data sources. This really isn't what I was hoping to do. The cluster users are regular users and are hoping to not have to learn special paths to data that they also use when not using the cluster. Once again, I simply want to make certain that non-cluster traffic has precedence. is there no way to do that without data segregation? And I'm really only looking for solutions that meet these criteria. > Also, I would dedicate a separate IDE/SCSI/whatever controller for the > NFS drives; can you separate the cluster's NFS directories from the > regular users? > -- > See above.

Install over NFS
by Thomas Paine 30 Jan '06

30 Jan '06

I'm trying to install FC5T2 over nfs. I googled and several sites say to just make an nfs share and dump the dvd iso file in there and you are good to go. I've tried this on my machine and I can't seem to connect to it with my laptop. I keep getting an error stating that the mountpoint doesn't seem to be a Fedora Core Installation Tree. my /etc/exports has just one line /nfs 10.10.10.0/24(ro,sync) which I have dropped the FC5 iso into. I didn't put the md5sum file though. And on my laptop I'm trying to install to I have my ip for the nfs server and the directory is just /nfs and I've tried it a few times and can't seem to get it to go. Any ideas? I don't have a DVD drive for the laptop to burn it to. Thanks. -- -=/>Thom

Memory leak?
by Jeffrey Ross 30 Jan '06

30 Jan '06

I believe I have a memory leak someplace on the system, over several days I watch the used memory slowly climb and eventually the system starts swapping, the application load has not changed. I have tried stopping processes and restarting them in the hopes that the memory would be returned to the system but no such luck. The system is Fedora Core 4, the main applications on the system are: mailman 2.1.7 (built from sources) exim 4.60 (built from sources) spamassassin 3.10 (built from sources) named 9.3.2 (built from sources) everything else was installed via yum and is the most current install available from the FC repositories. These programs are: apache 2.0.54 postgresql 8.0.6 (used for exim's databases only) perl 5.8.6 python 2.4.1 imap/popd version ?? sshd (Open SSH) 4.2P1 Kernel 2.4.16-1 How can I track down the source of the memory leak? according to "top" spamd (spamassassin) is the largest consumer of memory, however it seems to stay pretty stable compaired to how fast memory usage is climbing TIA, Jeff

Autorun at startup
by Anne Wilson 30 Jan '06

30 Jan '06

Whenever I boot my elderly laptop (FC4 + kde) I see an autorun tab appear on the taskbar, and an icon with a disc on my pointer. This goes on for several seconds. Is that normal? The price of a slow laptop? Or something that needs configuring out? Anne -- Registered Linux User No.293302 (http://counter.li.org/)

iso disk problems
by Anne Ramey 30 Jan '06

30 Jan '06

I'm trying to create iso disks for fedora core 3 i386. So far I have 3 coasters, two that won't boot and one that boots up, but is corrupt. Is there a better way to do this? I've downloaded the isos directly from redhat and I've used two different computers to do the CD burning. Is there a way I can get the needed info over the newtork directly onto the machine itself for a new install...maybe using the rescue CD? Anne

30 Jan '06

I see vlc.i386 on livna-stable, and when I go to "yum install vlc.i386", for the last few weeks, I always get the same set of missing depenencies: Error: Missing Dependency: libavcodec.so.51 is needed by package vlc Error: Missing Dependency: libavformat.so.50 is needed by package vlc Error: Missing Dependency: libavutil.so.49 is needed by package vlc Error: Missing Dependency: libpostproc.so.51.0.0 is needed by package vlc Any ideas on how I can find where to get the above libraries from?
