[Bug 481203] Re: Hardy 8.04.3 openssh does not forward X11 always cannot open display
Openssh forwards X sessions correctly after the /etc/hosts is fixed with a correct localhost IP (127.0.0.1 instead of 127.0.1.1) ** Changed in: openssh (Ubuntu) Status: Incomplete => Invalid -- Hardy 8.04.3 openssh does not forward X11 always cannot open display https://bugs.launchpad.net/bugs/481203 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

X11Forwarding is ON: ... X11Forwarding yes X11DisplayOffset 10 ... And xauth is installed, when I connect (the first time or after removing .Xauthority) I get: /usr/bin/X11/xauth: creating new authority file /home/admin/.Xauthority The Display variable is OK: $ echo $DISPLAY localhost:10.0 The port 6010 is listening (I guess this maps to X display #10): $ netstat -pan |grep 6010 (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) tcp0 0 127.0.0.1:6010 0.0.0.0:* LISTEN - tcp6 0 0 ::1:6010:::*LISTEN - I can even connect manually to port 6010: OOOPps! I got it! I could do telnet 127.0.0.1 6010 BUT NOT telnet localhost 6010... The problem was my /etc/hosts!!! It was: 127.0.1.1 madcvd01lnx.rfranco.com localhost madcvd01lnx Now I have fixed it to: 127.0.0.1 madcvd01lnx.rfranco.com localhost madcvd01lnx And gedit starts up correctly. What does 127.0.1.1 mean anyway? (I think that value was there in the defaul config for /etc/hosts) Does it have a reason or is it just an errata? Does it have anything to do with IPv6? -- Hardy 8.04.3 openssh does not forward X11 always cannot open display https://bugs.launchpad.net/bugs/481203 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Ah, something a forgot to mention. I compared a ssh -vvv session against a working fedora server and could not see any difference except for that in the hardy server, once the ssh connection is established, when I do gedit (or xhost +) I just get the error 'can't open display' and no debug info messages... whereas in the fedora box I get ssh debug messages (levels 1,2 and 3) just before the gedit pops up. -- Hardy 8.04.3 openssh does not forward X11 always cannot open display https://bugs.launchpad.net/bugs/481203 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
