domain name server

Dietmar_3 — Mon, 19 Jan 2004 07:57:47 GMT

I have recently installed HP-UX11 and during bootup I get the following error when the mail server boots up
"Unable to qualify own domain name server - using short name"...
The server runs of a static IP and after bootup I can access the mailbox?

Thanks D

This looks like a sendmail message. Check /etc/mail/sendmail.cf for the Dj macro.

Normally you can fix this with entering your servers FullQ-hostname+IPaddress as first entry in it's own hostfile (/etc/host) just after the localhost entry.

Your mail daemon is unable to get the fully qualified domain name of the machine it is running in. Try to check /etc/hosts and /etc/resolv.conf files.

Peter's answer above is right, you need to add the fully qualified name. The one slight change I'd make is he says to have the IP plus the fully qualified name. I'd just add the fully qualified name to the current line in addition to the hostname that is already there. What I mean is change

192.1.1.1 servername

to

192.1.1.1 servername servername.domain.com

instead of just

192.1.1.1 servername.domain.com

Having both there makes your life easier since the machine will recognize both the short hostname and the fully qualified name.

Ralph is right, adding the short name I already assumed you had already filled in the host file.
Having the shortname in /etc/host makes live more easy.

When you are done making changes a test:

sendmail -v -d8.99 -d38.99 someone@somedomain.com

type some text

.

This will validate the changes very nicely.

Before sending the mail SEP is sugesting(what is a good test), check if the server resolves the domain you are addresing with nslookup.

I know in our situation we wanted to send to a domain that was not resolved by our (internal) DNS server. To fix this we put a fake IP adres for the domain in the hostfile of the server running sendmail like:

1.1.1.1 someone.com

Then send mail connects to the relay host and sends the mail correct. Without the entry in the hostfile it did not send any mail addressed to that domain to the relay host.
