[ale] ftp - no route to host???

If the error was connection refuse, or connection reset, I'd say it
was either a firewall on the box or by his ISP. But, "No route" means
his client does not know that it has a network interface capable of
routing traffic to the given host (which in this case is specified by
an IP address). Although he is able to reach it via SSH and UDP ping.
That's jacked up.

Maybe try:
echo $IP_ADDR # make sure you have the right var/value
host $IP_ADDR # seeing if you can do a [reverse] lookup on the var/value
telnet $IP_ADDR 22 # standard ssh port number
telnet $IP_ADDR 21 # standard ftp port number

If you get "No route to host" from one of those telnets and not the
other... evil is afoot.
