I recently reconfigured some CentOS 4.3 systems that were using DHCP
to use static IP addresses. At the same time, the systems were moved
to a new VLAN. Here is the approximate sequence of events that took
place:
1. ifdown eth0
2. edit /etc/sysconfig/network-scripts/ifcfg-eth0 with static IP
address
3. wait for network folks to reconfigure switch
4. ifup eth0
I may have reversed steps 1 and 2 on some of the systems.
The problem was that the dhclient process didn't go …
[View More]away, and kept
renewing the old lease. Our DHCP server is configured to contact the
DNS server and update the entry for each host it serves. So the DNS
entries for these systems were pointing to the old address in the old
VLAN. The eth0 interface itself just kept the static IP address for
which it was configured. It took me a while to figure out what was
going on.
My question is, what could I have done to avoid this (other than
killing the dhclient process)? Is there a better way to reconfigure
an interface to use a static address? I am not interested in
solutions that involve using a GUI (i.e., only command line solutions).
Thanks,

In CentOS 4.1/2, what package contains this library:
libstdc++-libc6.2-2.so.3?
I installed a couple of the compat- packages, but this library is still missing.
I have an old RHEL3 box that I am upgrading to CentOS5. I picked up a
new Dell Poweredge R200 to use for that.
Is there an easy way to copy all the user accounts and existing mail
from the old server to the new one?
Thanks.

We are finally going to replace our VHS-C Camcorder, with a Digital
Camcorder, tomorrow. Looking for suggestions,
for Digital Video Editor to use on CentOS 5.2. Preferably, something
in the CentOS or RPMForge repositories and easy to use. TIA!
I have a 500GB Sata drive about 15% used I would like to make an exact
copy of too another Sata 500GB drive as a spare. That way if
something happens to the one in service I can plug in the spare
quickly and restore one of the weekly backups without reinstalling the
entire OS and all the little tweaks of setup on this mail/web server.
How do I do this? That is make an exact bootable copy of a linux
drive. Its running Centos 4.6 if that matters.

I was wondering if anyone else had this problem.
I run CentOS 5.2 x86_64 on my workstation at home. Since 5.2 came out
with nepluginwrapper bundled into it, none of my plugins work. I
thought it was just a problem with the flash plugin, but neither the
mplayerplug-in plugins nor the adobe acrobat reader plugin work,
either.
I have this problem both with the Seamonkey contributed 64-bit build
and my own (otherwise perfectly working) native build of the 2.01a
pre-release trunk build (which I …
[View More]have been using since January, with
occasional updates, the most recent being about a week ago).
I have not tried going back to the 32-bit release of Seamonkey,
although I suppose that's next. I stopped using that when it kept
crashing when I tried to save a web page after having visited some
unknown threshold level of pages (i.e., it wouldn't do this on the
first or second web page, but somewhere down the line, a threshold was
crossed and it would crash fairly regularly). In discussions with the
Mozilla folks, I concluded that the problem had something to do with
running the 32-bit release on my 64-bit OS. Due to some peculiarity
in the 1.x Mozilla build process, I was never able to build a 64-bit
version of the 1.x releases, but I had no trouble running the L&G
not-yet-released revision, with occasional glitches from the bugs that
I ran into (and reported).
But, back to the point:
There are two major issues I have with the 5.2 bundled nspluginwrapper:
1) The nspluginwrapper program itself is gone, which makes it a little
(lot) harder to manage and troubleshoot the problems.
and, more importantly:
2) None of the 32-bit plugins that are supposed to be wrapped work. Period.
Is this something I should report in bugzilla, at CentOS (and
upstream)? I didn't see it in the bugs listed at CentOS.org.
Thanks.

I have a USB drive that has been formatted as NTFS. Can I reformat it?
I have identified these properties about it
/dev/sda1
/media/Extrnl_Bkup
Not sure what to do next since the GUI will not mount a NTFS disk
(expected).

So I'm running nfs to get content to my web servers. Now I've had this
problem 2 times (about 2 weeks since the last occurrence).
I use drbd on the nfs server for redundancy. Now to my problem:
All my web sites stopped responding so I started by checking dmesg and
there I found a bunch of this errors
||
Aug 11 16:00:39 web03 kernel: lockd: server 192.168.20.22 not responding, timed out
Aug 11 16:02:39 web03 kernel: lockd: server 192.168.20.22 not responding, timed out
But when checking …
[View More]the nfs server lockd was running and I could access
all the files from the webserver with ls, cd etc.
The logs on the nfs server doesn't say anything of interest and checking
apaches error_log just says "not found or unable to stat".
Now I mentioned this have happened 2 times and both these times I've
"solved" it by rebooting the nfs server and web servers. This isn't a
good solution to have to reboot my servers every couple of weeks so I
really could use some help. :)
Also I get this from time to time on the web servers, dunno if it's related.
