I sort of found the solution to my problem, but still do not fully
understand what happened. First I thought I had to add X to the server's
use flags. Looked like I then had DISPLAY set, but still got the warning
about missing xauth data. When trying to start an X application, I got
this:
Xlib: connection to "localhost:10.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
xterm Xt error: Can't open display: localhost:10.0
Then I looked at the configs again, and in the man page for ssh_config I
finally found this:
XAuthLocation
Specifies the full pathname of the xauth(1) program. The
default is /usr/openwin/bin/xauth.
/usr/openwin? I added "XAuthLocation /usr/bin/xauth" to the
client's /etc/ssh/ssh_config, and now all was fine. Even without the X use
flag.
Looking at a gentoo box I did not update for a while, I see the man page
there tells the default location is /usr/bin/xauth. Okay, now I know this
change is responsible. But why aren't forum and this list flooded with
people experiencing the same problem as me?
