Yes: Your nameresolution does not fit with your hostname and network
settings.

If you use the machine in a network the first step should be:

remove /etc/resolv.conf


/etc/hosts has to look like this:
------------------------------------
127.0.0.1 localhost loopback
xxx.xxx.xxx.xxx hostname hostname.
------------------------------------

xxx... is your IP adress. check it with netstat -in

hostname is the name you use in SYSTEM_NAME

watch the hostname_dot_ alias in the second line. It is required to keep
sendmail satisfied.




/etc/nsswitch.conf should look like this:
----------------------
hosts: files
networks: files
protocols: files
rpc: files
publickey: files
netgroup: files
automount: files
aliases: files
services: files
----------------------
