due to restrictive net connection i need to TCPconnect through Qizmo to other Qizmos.
the problem is i don't know the Qizmos with open TCP ports and what are those TCP ports.

can someone help?
this info might be useful for others with ISP restrictions as well

I doubt there are any Qizmos which allow you to connect through TCP, although I know this works.
One of the Polish admins had tested it, believed to be a quite good feature, although the drawback, as you may imagine is having to open an additional TCP port which somehow seems to be a problem.

I think CSN qizmo has a TCP port but I'm not sure

Btw, what kind of ISP would that be? Uni?

chosen(1) allowed .tcpconnect to port 30000 if i remember correct, dunno why it's been down lately, skynet.campus.luth.se:30000 allows it ;O, seems like chosen2 does not . It would be easier if qizmo admins used the same port for udp and tcpconnections (qizmo -p 30000 -x 30000).

i have never tested but Dybbuk Gehenna Qizmo should also accept tcp connections. try the same port as udp. dunno if it is fast enough for you though.
