It means that the machine doesn't know how to get to the other one.
Check that the IP address actually falls within the range of the other
ones.  The subnet mask will play an important part here.

You could try:

1) Renumbering Dirty to fit in with the other's scheme.

2) Add a specific route to Dirty using route(8).

3) Use PLIP and a parallel connection instead.  :-)

It's a little difficult to tell without any information.  Could you send
us the output of "ifconfig -a" and "netstat -rn" from both Dirty and
Harry so that we can have a better guess at what's going on?
