[olug] potato post-install question

[Phil Brutsche]

A long time ago, in a galaxy far, far way, someone said...

1) I dunno (the ipv6 question)
2) No.  I don't have a sit0 on any of my computers...

What's the output of
 * ifconfig -a
 * route -n

and the contents of the file /etc/network/interfaces?

In potato, the interfaces are configured in /etc/networking/interfaces, as
well as any static routes for each interface.  The commands 'ifup' and
'ifdown' also configure the default gateway, if you have one set.

This is the important stuff from /etc/network/interfaces on one of my
computers (everything else were comments):

iface lo inet loopback

iface eth0 inet static
        address 192.168.0.2
        network 192.168.0.0
        netmask 255.255.255.0
        broadcast 192.168.0.255
        gateway 192.168.0.3

Note the 'gateway' line - when 'ifup' is called at boot time 'ifup'
automatically does the 'route add default gw 192.168.0.3 dev eth0' for me.

If you're relatively new to Debian, I strongly recommend that you
subscribe to the mailing list debian-user - you can find subscription
information at http://www.debian.org/MailingLists/subscribe

Be aware, however, that it can be a high-volume mailing list.
