Hi there I'm running openvpn as a client under XP and Win7 (binary from openvpn.net) over UDP with the "nobind" option. "netstat -anb" shows openvpn.exe is attached to local port 1194. I'm running it as a service BTW.
In general it works well, but once in a while, restarting openvpn doesn't work - you get some vague "cannot access" error. Waiting some minutes or rebooting will always fix the problem. Ends up that running "netstat -an" in this situation shows that something is associated with udp port 1194 - svchosts.exe. When this happens, waiting until 1194 disappears from netstat means I'm able to start openvpn successfully. So there's a couple of issues. As I was using "nobind", shouldn't the OS have allocated the port? i.e. why is it always 1194 - not 20111 or the like? Secondly, as it's "nobind", shouldn't openvpn have allocated the next free port instead of trying to reuse 1194? Finally, any ideas why openvpn doesn't cleanly exit all the time. I also use openvpn client under Linux and it never shows these symptoms, so I'd guess these are all win32-specific. Thanks -- Cheers Jason Haar Information Security Manager, Trimble Navigation Ltd.
