While setting hostname from WHM >> Change Hostname
We were seeing below error
“The hostname was already set to server1k.online.net, syncing configuration only.
Error setting new hostname: Could not execute hostname binary
Could not set property: Connection timed out”
After googling found a alternate solution to this via cli
The command was /usr/local/cpanel/bin/set_hostname <hostname>
It would and could change hostname 🙂
