Very possibly not. I am doing NAT on this box. The hostname is
'BASE.MURRAYDOMAIN'
But ifconfig knows of:
eth0 - inet addr:168.254.0.1 Bcast:168.254.0.255 Mask:255.255.255.0
lo - inet addr:127.0.0.1 Mask:255.0.0.0
ppp0 - inet addr:172.214.160.107 P-t-P:81.145.240.249 Mask:255.255.255.255
tun0-00 inet addr:172.161.242.134 P-t-P:172.161.242.134 Mask:255.255.255.255
This mess is because I use a hacked 'penggy' to make connection to the AOL
xDSL service. ppp0 is brought up, but does nothing without the tunnel.
But it all seems to work (ssh, browse, tunnel etc)

Tried this and that. Never seems to make any difference at all.
Is that suspicious? It was 'ipt.aol.com' for much of this. But removing
it changes nothing. ctladdr is always root@xxxxxxxxxxxxxxxxx
>What is the output of "hostname" on this box?
base.murraydomain
Thank you very much! This is really confusing me.
