Hello, I have a problem connecting to one of my computers using tinc 1.0.x on Windows. It used to work, now it suddenly stopped (and nothing changed :) ) We have a server with a known ip address and port forwarding set. All computer connect to this server. I can ping from my computer (laptophenk) to the server and some other computers but not to jeffrey2015. When I set tincd to -D -d4 I get ( I left out a lot of data of course) UDP address of vpnserver set to ...... port 655 UDP address of jeffrey2015 set to ...... port 655 Got ANS_KEY from vpnserver (..... port 655): 16 jeffrey2015 laptophenk F.....E 91 64 4 5 ..... 33487 Using reflexive UDP address from jeffrey2015: .... port 33487 UDP address of jeffrey2015 set to ..... port 33487 Receiving packet failed: (10054) An existing connection was forcibly closed by the remote host. Receiving packet failed: (10054) An existing connection was forcibly closed by the remote host. Receiving packet failed: (10054) An existing connection was forcibly closed by the remote host. Receiving packet failed: (10054) An existing connection was forcibly closed by the remote host. Receiving packet failed: (10054) An existing connection was forcibly closed by the remote host. I have tried to set the connection to TCPOnly (I know it is deprecated). I don't get the error, but still can't ping jeffrey2015. All computers are on separate internet connections behind their own modem/router. All computers run without the Microsoft firewall, or any other Windows firewall. Get somebody shed some light on my problem? How can a connection be closed when all data is send using UDP? -------------- next part -------------- An HTML attachment was scrubbed...

Thank you for your response. Yes, I know something changed, hence the smiley. I have looked at the code (I was able to build it under the new windows bash). It turns out that the error was on a udp receive, not a tcp connection. Didn't know you would get this error. Anyhow near the location of the error there was a remark about IPv6. I hadn't looked at that yet. So I turned IPv6 off at the client that could not be reached and now it works. Maybe I should look at when and how to use IPv6 someday, when there are more than 24hs in a day. Now I'm happy it works. -----Oorspronkelijk bericht----- Van: tinc [mailto:tinc-bounces at tinc-vpn.org] Namens ????
