: I've run into a problem. I'm on a company network. On another
|
||||
: machine, I ran RH 6.2, and would connect to a Sun box using ssh. On
|
||||
: my local term window, I'd do something like xhost +fred, then go ssh
|
||||
: -l user fred. When I got on the 'fred' box...I'd do export
|
||||
: DISPLAY=my ip address.

|
||||
Instead, simply ssh to the sun box. Don't xhost. Don't reset the DISPLAY.
|
||||
Part of the point of use of ssh is that it redirects your X connections
|
||||
to the secured, encrypted channel it creates, without creating additional
|
||||
authentication with xhost. By using xhost, you defeat the security of
|
||||
the authentication ssh does, and by resetting DISPLAY, you are
|
||||
throwing away the work ssh does to proxy your display.

: My problem: I'm on a different box now...Just installed RH 7.2....I
|
||||
: can ssh onto Fred...I follow the exact same steps with xhosts...and
|
||||
: export DISPLAY, but, I keep getting this message:
|
||||
:
|
||||
: emacs: Cannot connect to X server ip address
|
||||
doc: html
|
||||
|
||||
Depending on your install, this is probably due to the fact that
|
||||
rh7.2 has stricter firewalling rules, and doesn't approve of unsecured
|
||||
remote access to the X display. Simply drop the xhost and DISPLAY reset,
|
||||
and all should be well. Oh, you might have to use "-X" on the ssh connection
|
||||
if rh7.2 doesn't configure X proxying on by default.

|

: Check the DISPLAY environment variable or use `-d'.

rm -fr $(HTML_DIR) *~ __tmp_htmls
|

|
||||
X is set up to use xauth authentication instead of xhost authentication.
|
||||
In use of xauth, only users that know the MIT-MAGIC-COOKIE for your
|
||||
display can access it. These secrets are stored in users' $HOME
|
||||
directories, in files permissed so other's can't read them.
|
||||
|
||||
Because, in fact, you *don't* want people to be able to access
|
||||
your display just because they happen to be running on the same machine.
|
||||
Requiring them to know the secret (ie, mostly, requiring them to be the
|
||||
same user) is much safer.
|
||||
|
||||
Look at the xauth man page. If you want to, you can pass along
|
||||
your xauth keys to your su-ed shell; the man page should say
|
||||
how this is done.
