Dear jprathap,

Please make sure X11 forwarding is enabled in both client and server configuration files of ssh on both the machines.

In /etc/ssh/sshd_config

Code:

X11Forwarding yes

In /etc/ssh/ssh_config

Code:

ForwardX11 yes

Restart sshd daemon on both the machiens

Code:

# /sbin/services sshd restart

also try this way
ssh -X root@192.168.1.11 /usr/bin/konqueror

Before 'ssh -X' run 'xhost+[<remote host>] to give the remote machine access to your display.

I find using this easier:

Quote:

# ssh -Y root@192.168.1.11

It avoids the having to turn on forwarding all the time.

Hi all...

I tried all the possible configurations as you mentioned. But i could not get what i expected.

My configuration is as follows

Quote:

# Accept locale-related environment variables
AcceptEnv LANG LC_CTYPE LC_NUMERIC LC_TIME LC_COLLATE LC_MONETARY LC_MESSAGES
AcceptEnv LC_PAPER LC_NAME LC_ADDRESS LC_TELEPHONE LC_MEASUREMENT
AcceptEnv LC_IDENTIFICATION LC_ALL
AllowTcpForwarding yes
#GatewayPorts no
#X11Forwarding no
X11Forwarding yes
X11DisplayOffset 10
X11UseLocalhost yes
#PrintMotd yes
#PrintLastLog yes
#TCPKeepAlive yes

What would be the prob?

Running xhost+ is not needed if ssh is configured properly.
Additionally, it has serious security issues and so should be avoided.

To help debug the problem please run ssh with the '-v' flag to get verbose output.

To debug a problem you should try to get all the information you can. In this case that means running your ssh client with '-vvv' flag and reading the sshd server logs (if you have access to them). If the above does not provided the information allowing you to solve your problem, post the information to the forum where it may allow other people to understand/solve the problem.
