I have some Linux servers (RHEL 6.3 and 5.4) under one domain (MS Windows server 2008R2) and every thing was working fine, but we decided to change the domain from olddomain.com to newdomain.com, now the new domain under (Windows server 2012), I changed the domain from the old one to the new one in all Linux servers.

The result of $dnsdomainname command is newdomain.com on all Linux servers. when I ping any Linux server from it give me Lin_name.newdomain.com but the problem I am facing now the log inside log rotate and forward still recognize the old domain. it give me like the following:

Nov 19 10.00.09 Lin_name.olddomain.com Lin_name [message like someone logged in or out start proccess ..etc]

Did you reboot or restart any of the Linux system services? If not, you'll need to...

Also see: Linux - if I change the hostname, which services need to be restarted?

  • Thanks, But I did that before asking the question. and if you ping the server it give you the new domain name but in the log it give you the old one – Ahmad Abuhasna Nov 20 '14 at 15:37
  • Did you restart the syslog or rsyslog services? – ewwhite Nov 20 '14 at 15:38
  • yes, I restarted the services – Ahmad Abuhasna Nov 20 '14 at 16:06
  • Did you rename the server? Check `/etc/sysconfig/network` – ewwhite Nov 20 '14 at 16:08
  • yes the server name under the new domain, the thing I don't understand if you ping the server using ping Lin_name it give you Lin_name.newdomain.com , but the log still write Lin_name.olddomain.com – Ahmad Abuhasna Nov 20 '14 at 16:11
  • For some reason, syslog isn't recognizing that the hostname has changed yet. The fact that `ping` shows the correct domain name just means that name resolution is working, nothing more. The fact that `dnsdomainname` shows the right information, but syslog doesn't makes me think that syslog (or rsyslog, or syslog-ng, or whatever logger your systems are using) didn't restart properly after the name change. – Hunter Eidson Dec 09 '14 at 14:45
