To change hostname, login to the server as root and just type

hostname newname

where newname is the new hostname to be set

When you set hostname in that way, changes will be available till the server is rebooted only. For the changes to be effevtive even after a reboot, make the change permanent by doing the following.

vi /etc/sysconfig/network (redhat/fedora specific)

Change HOSTNAME=newname

Save and quit.

Alternatively, check the /etc/hosts file and see if the old hostname is present there. IF yes, correct it as well.

Sometimes, when you login to an account’s cpanel as reseller, there should be a drop down box to switch to the cpanel of various accounts under that reseller. If it is not present, you can check the following things.

In WHM -> Tweak Settings -> make sure the following option is not checked.

Disable login with root or reseller password into the users’ cPanel interface. Also disable switch account dropdown in themes with switch account feature.
