This is OSX 10.6.5 running Parallels Desktop 6.0.11990, there is no firewall active. The other system is Fedora core 8 running linux 2.6.26 with Parallels transporter Agent 11990-621014 installed. The install did not produce errors. The firewall has been opened up to allow ports 1620-1623 on both tcp and udp. The two machines can ssh into each other so network connectivity is present. When I fire up the transporter agent it sits there saying "ready to connect", On the OSX side it tries to connect for a minute or two then comes up with an error suggesting I check the ports are open. Nothing seems to be logged on the Linux side. I cannot find any transporter log on OSX and nothing is logged in Library/Logs/parallels.log. What now?
