Hello people,

recently I have installed Ubuntu 11.04 to VPS and have changed hostname using following steps:
1. Create /etc/hostname file and put "mydomain.com" to it
2. Edit /etc/hosts file and put these new lines:
Code:
127.0.1.1  mydomain.com
123.456.789.0 mydomain.com

where 123.456.789.0 is IP address of VPS.
3. Type as root:
Code:
# hostname mydomain.com


After these operations, hostname was changed, but it has been reverted back to default Linode's value in three cases:
1. Just after some hours.
2. After VPS reboot.
3. After doing
Code:
# service networking restart

I have no this problem with older Ubuntu versions: 9.10, 10.04, 10.10 on Linode VPS.

Thanks waldo!

I have commented SET_HOSTNAME='yes' in /etc/default/dhcpcd and at least after restarting "networking" service, hostname has not reverted.

Thanks, Waldo. So useful!

I am a cloud newbie and can see why dhcpcd is used and why I never hit this one before. Saved a lot of pulling out of hair!

If you have not already done so, try rebooting the linode. That is what it took for one of the debian systems I'm managing to finally get in line.

Make sure /etc/hostname contains the correct hostname for your server prior to rebooting.

You are welcome, however before you jump for joy check it in a few hours and see if it reverted, if not then cheer.

Good luck. :)
