How qualify the domain of the server

[bipromeco]

Hello All
Do you know why my server send this message:

Dec 10 14:59:22 nameserver sendmail[915]: unable to qualify my own domain name (nameserver)- using short name.

Thanks in advance.

Regards!

bipromeco,

This is a very common problem.
I've been down this road many times. Here is how you fix it.

FIRST, edit the /etc/hosts file, adding an alias with a period. So if your system name was hplab1 it would look something like this.

192.168.1.1 hplab1 hplab1.

NEXT, edit the /etc/mail/sendmail.cw file adding the same entry that we did to /etc/hosts. This should be toward the end of the file.

localhost
hplab1
hplab1. <--------add this

Then stop/start sendmail and the message should never come back.

/sbin/init.d/sendmail stop
/sbin/init.d/sendmail start


Hope this helps.
