loopback absent in routing table

[Judith Elaine Bush <debian@grey-cat.com>]

Long story short: a friend began the setup of a debian box for me (i'm
a little overbusy with work and a very long commute), wasn't familiar
with debian, never seemed to "get it," eventually gave up in
frustration.

So, i'm now trying to decipher the setup of a box with stable r 6
installed. 

We have a home LAN behind a Linksys DNS router. The Debian box has a
static routing path set up in the Linksys system. 

telnetd is running on the Debian box.  

>From one of the laptops we can telnet to the Debian box's IP
address. The connection happens almost immediately (a log in syslog
and, depending on the telnet client, the message that connection has
been made appears). Then there is a very long wait before the login
message appears.

Running route (which takes a small forever) and route -n (which is
quick) indicates that the problem is with DNS. We are not running a
DNS server on the machine (yet).

We've been stepping through the (old) network administration manual at
http://www.debian.org/doc/manuals/network-administrator/

Looking at the output of route, we note that there is no entry for
destination 127.0.0.0 nor any entry for Iface=lo.

We tried the command 
	$ route add -net 127.0.0.0
and got the error
	SIOCADDRT: invalid argument.
 
We looked at the ifconfig output for the lo device and noted that
there is no broadcast IP and that BROADCAST isn't running.

Is this a problem we need to fix? 


Lots of info below,

Thanks for your help in advance.

Cheers,
