Hi,
I'm using Debian 5 w/ mutt, postfix, fetchmail, procmail. I have discontinued my mtnl triband and taken a reliance broadband netconnect connection.
I've configured the stuff in the usual way but fetchmail is acting up. These are the error messages.
fetchmail: connection to localhost:smtp [::1/25] failed: Network is unreachable.
Your lo interface is not up for some reason. Try a /etc/init.d/networking restart (or the equivalent in your distribution). ifconfig, ping 127.0.0.1 and route -n are your friends for determining whether the interface and the local route is up or not.
/etc/init.d/networking restart just says networking restarted.
I get errors of network unreachable.
I'm not at that machine right now so I'l give you the output of the other stuff tomorrow.
Ok, i'm back at the machine. Postfix refuses to start with this error.

After I bring up lo, postfix starts up normally. As an aside, while installing, debian had barfed on setting up the network. I had to go into expert install and skip that step as it complained of not finding a network interface.
What now ? Why is lo not coming up automatically ?
thanks,
