Hi

I have a computer, that is connected to the Internet from within a LAN,
through a gateway. Thus my net was set up as 10.0.4.15, &c. According to
the 'NET HOWTO'  those numbers nor the name, Archimedes.brisen.rings.se,
should never be sent out on the Internet.
How come my name is set up in mc as root@Archimedes.brisen.rings.se.
Where is this information stored so that I may change it to my email
address?

regards
guran
