[Bug 481203] Re: Hardy 8.04.3 openssh does not forward X11 always cannot open display

[Jose L. VG]

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.)
tcp        0      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?
