Hi all,
Netsend can block, but I don't think netreceive does. Netsend's behavior seems OK on linux, W2K, or NT; I don't know about XP.
One hint would be to use the IP address and not the domain name when making connections (or, if you can figure out how to do it, hardwire the host names to teh IP addresses) so that your machine won't try to contact a name server as part of "connect".
I do want to make a threaded version of netsend someday, but I'm trying not to add things to 0.35 (just fixing bugs.)
cheers Miller
