How to display xclock on another computer?
Solution 1
On my computer (111
):
ssh -X 192.168.0.222
followed simply by:
xclock
will run xclock
on the other computer (222
) and display on my computer (111
).
Note: For this to work X11Forwarding
should be enabled in /etc/ssh/sshd_config
at computer (222
)
Solution 2
Two things to check for: Port 6000 needs to be open on the 222 machine (configure or disable the firewall), and the X server itself needs to be listening on that port. This is often disabled in modern distros. Check if it's listening with
# netstat -nltp | grep 6000
tcp 0 0 0.0.0.0:6000 0.0.0.0:* LISTEN 10818/Xorg
tcp6 0 0 :::6000 :::* LISTEN 10818/Xorg
If not, you can enable it for gdm in /etc/gdm/custom.conf
[security]
DisallowTCP=false
Logout/restart gdm on the 222 machine and log in again. You should then see Xorg listening on port 6000.
Solution 3
And you can do simplest :)
$ ssh -X 192.168.0.222 "xclock"

I want to display
xclock
on another computer.On my computer (
111
) I am able toping
the other computer (222
) inside my home network:$ ifconfig wlan0 wlan0 Link encap:Ethernet HWaddr 44:55:66:77:88:99 inet addr:192.168.0.111 Bcast:192.168.0.255 Mask:255.255.255.0 $ ping 192.168.0.222
The router is a D-Link DIR-655 Wireless N Gigabit Router.
$ xclock -display 192.168.0.111:0
Displays the
xclock
on my computer (111
) as expected. On the other computer (222
):$ xhost +
But then back on my computer (
111
) it also displays on my computer when changed to:$ xclock -display 192.168.0.222:0
To attempt to verify the use of the
-display
switch:$ xclock -display 192.168.0.111:0.1 Error: Can't open display: 192.168.0.111:0.1 $ ping 192.168.0.333 ping: unknown host 192.168.0.333 $ xclock -display 192.168.0.333:0
I would expect it to fail but it also displays on my computer (
111
) but with a bit of a delay. These results tells me that thedisplay
argument is getting toxclock
.$ uname -a Linux mycomputer 3.2.0-27-generic #43-Ubuntu SMP Fri Jul 6 14:46:35 UTC 2012 i686 i686 i386 GNU/Linux
I am using LXDE rather than GNOME or KDE.
I am only attempting to get
xclock
to display and am not interested in addressing security issues in this question. -
