Actually I must confess, I'm sort of trolling. I'm the author of jCIFS
(the SMB client) and I wanted to know how you addressed this problem. I did
not know eventually a Connection timed out exception is thrown. This is good
news. I have done a bit of research elsewhere and found out 1.4 does indeed
have a timeout parameter for the Socket constructor. Unfortunately that doesn't
help me because jCIFS still supports 1.1 and it would be a shame to break that.

Tried and failed. If you look up my ([EMAIL PROTECTED]) recent post to
comp.lang.java.programmer you'll see I tested this by trying to interrupt() the
Socket() calling Thread. The results depend on which jre you're using but both
end up sticking in Socket() in an interrupted state.

With JNI?

JDK 1.4 has a timeout parameter for Socket().
