Question need help running remote X applications


Hi,

I need help allowing remote X applications to run on my local sarge box. As a simple test, I tried to get a local X application running on my local machine via setting the DISPLAY variable. The application runs fine if I don't define DISPLAY, but fails if I try to use localhost for DISPLAY. For example:

Code:
$ gedit
$ xhost +localhost
localhost being added to access control list
$ DISPLAY=localhost:0.0 gedit

(gedit:4051): Gtk-WARNING **: cannot open display:
Since I can't get local X applications running like this, I doubt I can get remote applications running similarly.

Not sure if it matters, but here is my /etc/hosts.deny

Code:
# /etc/hosts.deny: list of hosts that are _not_ allowed to access the system.
#                  See the manual pages hosts_access(5), hosts_options(5)
#                  and /usr/doc/netbase/portmapper.txt.gz
and /etc/hosts.allow

Code:
# /etc/hosts.allow: list of hosts that are allowed to access the system.
#                   See the manual pages hosts_access(5), hosts_options(5)
#                   and /usr/doc/netbase/portmapper.txt.gz

service:host
ALL:127.0.0.1
Thanks for any thoughts.

you shouldn't have to do any of that to run remote x apps just:

ssh -X 192.168.0.1 (or whatever the ip)

and it should take care of all the forwarding for you. have you actually tried this with another machine? or do you just have the one computer? if so why would you need to run remote x apps?

i tried running X apps from a remote system, and it didn't work, which is why i tried something simpler.

I tried your approach, but I still can't run X applications.

Code:
$ gedit
$ ssh -X localhost
Linux 2.6.8-2-686 #1 Thu May 19 17:53:30 JST 2005 i686 GNU/Linux
$ gedit

(gedit:4158): Gtk-WARNING **: cannot open display:

whats in the sshd_config on the server side? maybe it's not set to allow x forwarding. why would trying to emulate x forwarding by using one machine be simpler? if anything I would say that that would be more complicated and less likely to work then using 2 computers.

ok, i tried loging in locally to my home sarge box (no extra security configuration) with "ssh -X localhost" and i was able to launch X apps correctly.

i used bastille to lock down my work system, so i just need to figure out which settings i need to relax. is there a way to use bastille to restore default settings? thanks.
