Unqualified Domain Name

I recently connected my Sun U10 to the adsl line here at home. Since I am also running a couple of PCs on it as well, I'm using the Linksys router (4 port). Everything appears to be fine with the exception of this annoying message upon boot up: Apr 15 15:46:52 sunu10 sendmail[201]: unable to qualify my own domain name (sunu10) -- using short name I've edited the appropriate files ( I believe) and listed the contents of each for your review: defaultrouter 192.168.1.1 pacbell.net resolv.conf domain pacbell.net nameserver 63.200.115.40 nameserver 206.13.28.12 search pacbell.net hosts 127.0.0.1 localhost 192.168.1.x sunu10 loghost I can go out onto the internet fine...email (PINE) appears to be fine. What did I do to upset sendmail?

Mine does this as well. It seems to be when the OS sends emails to a user when some events happen, like adding entrys in the syslog. Try leaving the terminal window open when you're setting something up (like a printer, or BIND) and you'll get a lot of them. Unfortunatly, I dont know how to fix it...

hello first make one changes in ur #/etc/resolv.conf entry remove domain OR search entry because both cann't co-exist each other. and more thing put a period entry in last of ur loop back entry line in #/etc/hosts that will solve ur problem. Anil Maheshwari

Thanks to you both....! nicomen

you can just add another alias whith a dot like this on your /etc/hosts 127.0.0.1 localhost 192.168.1.x sunu10 sunu10. loghost because sendmail on solaris 8 search un qualify host with domain dns like sun.com.
