Hi,
thanks for the reply, I sometime back changed the hostname using the
/etc/sysconfig/network only. However, that only has 2 lines in it-
Networking=Yes, Hostname=sipx.com

Where can I edit the dnsdomainname and domainname variables? I do not see
those variables in /etc/hosts or /etc/sysconfig/network.

Thank You

Hi all,

I am running centos 5.1 and I wish to change the domain name and
dnsdomainname of my PC. currently the settings are--

$ hostname
sipx.com <http://sipx.com>
$ hostname --fqdn
sipx.com <http://sipx.com>
$ domainname
(none)
$ dnsdomainname
com

I have searched in the net for tips but everywhere only the hostname
change is provided. I need to change/set the domain name and the dnsdomain
name on my pc to sipx.com <http://sipx.com> and this should be a
permanent one across system reboots. Please let me know how to do this.  The
domain name settings are required for a networking/ SIP telephony
applications that I am running but it is internally in the LAN, so I think
the name sipx.com <http://sipx.com> if chosen as my pc's domain name will
not cause any conflict with the external domain names in the Internet.

Thank You

Edit /etc/sysconfig/network
Restart

IF you have 3 names in your host name it will work ... it will not work with just 2 names.

you need host.domain.com

right now, your host is sipx ... you have NO DOMAIN NAME except .com

you can easily then also set and alias in /etc/hosts to sipx.com ... and also use an alias in apache as well.

If you use a proper FQDN with 3 names then everything will "JUST WORK" ....

Take this name that I use:  myth.home.local

$ hostname
myth.home.local

$ hostname --fqdn
myth.home.local

$ dnsdomainname
home.local

Note:  use also used the domainname command, that command has nothing to do with dns names, but with "the system's NIS/YP domain name".

Thanks,
