[SOLVED] hostname not surviving reboot

[flsimbeck]

Here is my issue, right now everything works, whe I reboot the server the host name appears to break, which breaks the admin staus, stats, and stats email, this is just what I've noticed.

I've run through these formus, the Wiki, and any just about everything else I could find, serveral times.

The ONLY way I can temporally resolve it (until next reboot) is to, as root:

hostname mail

As soon as above is run, everything works. (no restart of anything required).

I have split DNS setup using a Win2k3 DNS server (.3), with a backup, slave Win2k8 DNS server (.5).

There has got to be an error somewhere in my config thats not letting things survie a reboot, I just can't seem to find it.

Here is all the normally requested Info:

cat /etc/hosts

127.0.0.1 localhost.localdomain localhost
192.168.87.60 mail.mydomain.com mail

# The following lines are desirable for IPv6 capable hosts
# ::1     ip6-localhost ip6-loopback
# fe00::0 ip6-localnet
# ff00::0 ip6-mcastprefix
# ff02::1 ip6-allnodes
# ff02::2 ip6-allrouters
# ff02::3 ip6-allhosts

cat /etc/resolv.conf

search mydomain.com
nameserver 192.168.87.3
nameserver 192.168.87.5

dig yourdomain.com any

This is driving me nuts, I've got lot of time into NOT solving this, any help would be appriciated.

What does it say in the /etc/hostname file?

/etc/hostname

mail

Thanks for the quick reply!

What's the contents of this file: /etc/sysconfig/network

[/edit]Oops, that was from the wrong distribution.

What I meant to ask was, when you did the command to display the contents of /etc/hostname did you do that after a reboot or after you had run the hostname command to set the name to 'mail?

[flsimbeck]

It was after the reboot and after reseting the hostname mannually.

I will try rebooting and recording info before resetting it.

Frank

[flsimbeck]

/etc/hostname did not change after reboot, before doing anything.

mail

hostname -a (same resultes for -s -f and -d)

hostname: Unknown host

After resetting hostname with

hostname mail

hostname -a and -s returned

mail

hostname -f

mail.mydomain.com

hostname -d

mydomain.com

Could you try this, delete the /etc/hostname file then use your favourite editor to create the file again with your hostname then save the file and reboot the server. Does that fix it?

That did it, although I don't understand why. The file contents and permissions are identical. Is this some kind of quirk with the OS?

Thanks a lot for your time, now thats resolved, the ony other issues I have is the AV/AS stats are always zero, and I know there is some spam being routed to the junk my folder, but I search the formus before I post this issue.

Again, thanks Frank.

If everything appears OK then the likely answer is that there are some unprintable characters in the file (as there probably was in this case), deleting and recreating the file just means you have the correct data in there and no extraneous characters. Glad you've fixed it.

I'd suggest you have a look at the wiki for details of the logger here: Logger (ZCS 6.0.x and later) - Zimbra :: Wiki That will give you an idea of how it works and at the bottom of that page there are some Troubleshooting tips. When you've been through that have a quick search of the forums for any similar problems and if you still have no data then post again in a new thread.
