Trying to access a vpn using ssh on 6.2 - STABLE. Haven't found an answer 
anywhere, and so I must be totally missing the right questions to ask or 
configurations to look at.

This problem is consistent regardless of port chosen or access method. I can 
duplicate at will with ssh. Here's the command that fails:

$ ssh -X -N -L 127.0.0.3:13390:192.168.1.44:3390 tyson@xx.xx.xx.xx
tyson@xx.xx.xx.xx's password:
bind: Can't assign requested address
channel_setup_fwd_listener: cannot listen to port: 13390
Could not request local forwarding.

I know that it can be done -- the guy next to me is working using Linux, but 
his answer to this issue was to edit the /etc/network/interfaces file. He 
figures that I didn't  have one or don't have the loopback started.
(his interfaces file):
~$ more /etc/network/interfaces
auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0


Here's my config info:
======================================
ifconfig output:
smedley# ifconfig

Maybe I need to get rid if the inet6 for the loopback?

Thanks!
