If I try to open a Telnet connection, and get "Network Unreachable", I am
assuming my route table is messed up, or missing a route. If on the other
hand, I get "Connect: Connection Timed Out" *every time* I try to open the
connection (for weeks), what should I assume, and how can I fix it?
See, my problems stem from some of our 300 users trying to send netmail. They
don't want excuses, they want to send netmail... My mailer says it can't get
the message through. I need to change things so that it can. One example is
the host RICE. They are up, but my connections time-out every time we try to
send mail. I seem to be able to send to person%rice@csnet-relay, but the
majority of our users just send mail to @rice, so it sits there for days until
I manually bounce it back to them.
All I wanted to do was determine if my packets were getting there (and also
other sites) so I could localize the problem.

From: Ron Natalie <ron@BRL-TGR.ARPA> Well, it depends... "Network Unreachable" can also mean that you have the right route and some gateway host or network interface in the route is down. "Time out" means some one in the path (either you or a gateway or the remote host) is ignorant of the routing or it is down, and the down state is not detectable. If all you want is a program to test various routes for debug purposes we have one for 4.2 BSD. Perhaps if you mentioned the hosts involved, someone may realize what your problem is. -Ron (as opposed to +Ron, I suppose).
