However, you don't want an '@' sign in a hostname: I guess you probably want that last line to read: 10.0.0.1 IBM-R40e IBM-R40e.point.ne.jp =20 > I had to supply 10.0.0.1 IBM-R40e@point.ne.jp because Gnome 2 complains > that it can not find it...So, I just invented it...I hope that it is > right... Possibly. It depends very much on your local configuration. If you have a local ethernet network and there is an interface configured to use that address, then that's good. If you don't have a local network using that address then you might get 'No route to host' type errors, in which case you can attach the hostname as an alias to the loopback interface, just so long as the localhost stuff is there as well: 127.0.0.1 localhost IBM-R40e IBM-R40e.point.ne.jp > One thing I do not I understand is that when I do: > %host localhost. > It will be give a "Host not found" response...But, my system is working > fine...What do you think is wrong with it... That just means you haven't got the localhost stuff set up in the DNS servers you use. That's OK -- having the DNS support is entirely optional, so long as you have the right settings in /etc/hosts.
