thanks, my result is about the same as you: 1) everything is accepted 2) except for my result of "pidof vino-server" is not 7892, everything else is the same as yours. so the default port is 5900. I've tried it today and it doesn't work. i didn't use LAN ip but the real one like i used to do.

Is it on by default? No, there is no firewalling by default. You can check this with $ sudo iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination (That output tells you everything is set to "ACCEPT" ) If you are using a router you might have to port-forward - assuming you are connecting from outside the LAN. Have you read the documentation I linked carefully? Also check if the server is running on the Ubuntu box: $ ps aux | grep vino should show a line like peter 7892 8.3 1.2 17024 6224 ? S 06:22 0:01 /usr/lib/vino/vino-server --oaf-activate-iid=OAFIID:GNOME_RemoteDesktopServer --oaf-ior-fd=45 or $ pidof vino-server 7892 That should show a number as above. Also worth a try: $ sudo netstat -nlp | grep vino tcp 0 0 <a href="http://0.0.0.0:5900">0.0.0.0:5900</a> 0.0.0.0:* LISTEN 7892/vino-server unix 2 [ ACC ] STREAM LISTENING 64798 7892/vino-server /tmp/orbit-peter/linc-1ed4-0-7e29fe2dc06d As you see, it is listening on port 5900 .
