Command execution in ubuntu

Question

My server is running on OS ubuntu 10.4.

When I run command "skype -callto userid" it makes a call using Skype user interface.

But when I run same command by connecting via SSH or

java code

Runtime.getRuntime().exec(command), its not working.

What could be the reason of such behavior?

cadams.. for code 'Runtime.getRuntime().exec(command)' here command is "-skype -callto userid" — raheem52, Commented Aug 19, 2015 at 16:50

I guess your problem is that Skype needs an X server to run properly. So you could enable X11 forwarding.

X11 forwarding needs to be configured on the client and server side:

On the server side enable X11 forwarding by setting X11Forwarding yes in /etc/ssh/sshd_config and restarting the ssh service service sshd restart. You might also need to install xauth on the server side.

On the client side you need to open the ssh connection with the -X parameter to enable X11 forwarding for the session.
