conferences. I´m able to connect to this server, but there´s no transmition of sound and video. So I scan with nmap -p 1-65535 [localhost] and look there only the lisenport 1720 is open. All other ports which should be open are closed. Is there any possibilty to open the ports by hand? I [snip]
It is perfectly normal for you to see only port 1720 open, since that's where the H.323 server is listening for incoming calls. The additional connections are only established later on, after they have been negotiated on the 'incoming call' connection. As such, you won't see any other ports as open, because there's no process listening on them. This is absolutely OK. See if you can increase the volume of output on your H.323 client and server and check what they say when you try to setup an H.323 session. And perhaps sniffing the network traffic will provide some insights as well. Tobias
