Re: network unreachable

You should read the pleasant coments generated in comp.mail.sendmail when
someone mentions Linuxconf. Currently Linuxconf is not recommended by
subscribers of bind-users, samba,comp.mail.sendmail for the simplest
reason:
Linuxconf does not keep up with the latest version specific commands and
frequently adds stuff that you didnt select. Like for example when you set
up NIC it adds all that IPX stuff.
