Re: FC4 bus error message at boot time

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.

No, none of them, as explained above.

Why should I do it, since I'm not interested in having it?

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,

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.

Install over NFS
by Thomas Paine
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.

Memory leak?
by Jeffrey Ross
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
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?

iso disk problems
by Anne Ramey
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?

by Jamie Bohr
Does any one know of a yum depot I can get Evolutoin 2.4 from for FC3/FC4?
I have googled and did not find any thing. I don't want to have to complile
it, too many dependencies. I found RPMs at www.linuxcompatible.org but
there was way to many things I had to update inorder to install it. I am
looking for a one-stop-shop to get to Evolution 2.4. Any guidence would be
great.
Thank you,
