adding some domains to /etc/hosts constantly

Question

I've added some local domains to my /etc/hosts on Ubuntu. But it rewrites it every time I reboot OS.

How and where can I add constantly my 127.0.0.1 mydomain.local?

UPD

Before reboot I edit /etc/hosts:

127.0.0.1       localhost.localdomain   localhost  mydomain.local

After reboot

127.0.0.1       localhost.localdomain   localhost

This is caused by a bug in Ubuntu NetworkManager and there is a workaround which is detailed in this document.

/etc/hosts should look like this:

127.0.0.1       hostname.domain.local hostname localhost

Also, put your hostname in /etc/hostname

If some other program (like networkmanager) keeps changing your hostfile, you could make it imutable.

chattr +i /etc/hosts

yep it looks okey, but it will be rewrited automatically to default after rebooting, so all my edits will be removed – fl00r Mar 15 '11 at 09:04
Does it revert to 'localhost'? – Bart De Vos Mar 15 '11 at 09:09
it reverts `127.0.0.1 localhost.localdomain localhost` – fl00r Mar 15 '11 at 09:14
Actually putting `mydomain.local` to `/etc/hostname` helps. Now `/etc/hosts` still rewrites but it adds `mydomain.local` to `::1 ... ` line. Thanx! – fl00r Mar 15 '11 at 09:17

Probably is because of NetworkManager. Did you tried

sudo chattr +i /etc/hosts

after modifications ? If is still not working try to remove write attribute from /etc/hosts.

sudo chmod -w /etc/hosts
