my linux box on a token segment has problems uploading via
ftp to solaris boxes on a particualr ether segment.
my upload session always sends exactly 1024 bytes and
then the session just hangs indefinitely until I stop the process with ctrl-z.  anyone know why?

I think/hope the solution to this prob may also solve
my mysterious remote X problems...

It sounds like either the conversion between ethernet and token ring is dropping packets, or a router between is dropping packets.

To explain further, UDP (used in FTP) is very poor for routing across faulty or problematical networks.  Unlike TCP, UDP does not have fault tolerance, which makes it an excellent way to test suspect networks, especially WAN links.

So, you have a networking problem unrelated to software.  You had best take a look at running a packet sniffer and finding out where data is being lost.  Both Solaris' and Linux' FTP software is well tested and well debugged, believe me... :)
