How to show xclock in remoting computer?

Hey,guys!
I encounted a problem today.

Having computerA(pc-a) and computerB(pc-b),and the ip of A is 192.168.1.111,the ip of B is 192.168.1.105,
I login B and startx.

I opened a console ,then do somethin like this:
[userInB@pc-b]#sudo xhost +
[userInB@pc-b]#ssh userInA:192.168.1.111
[userInA@pc-a]#export DISPLAY=192.168.1.105:0.0
[userInA@pc-a]#xclock

Then I get the error: cannot open the display 192.168.1.105:0.0

Why? And how to make the xclock of pc-a run in pc-b ?

I am not sure if I have made it clear.If you have any question of it or want more information,please ask me.

Looking forward to your answer.
Thanks!

to allows graphical interfaces of X11 programs running on a remote system to be displayed on a local client machine,
I thought X11_forwarding of ssh is one method but not the only one.

I search in internet then I think it is one feature of xorg,and it is not rely on ssh.

Is my idea wrong?

then do somethin like this

First: "something like this" is no useful information because it implies "but could actually be totally different"
Second: what you *seem* to do there somewhat contrasts with what you apparently want to do.

=> Do you want to run the xclock *process* on A or on B? Shall it use the X11 server on A or on B?

Assuming it's actual forwarding: you can either use "ssh -Y" or allow the X11 server to open a tcp port (and then won't need any other mechanisms, you eg. set DISPLAY=server:0.0 if the remote port is 6000)
The latter is discouraged and deadly in hostile environments.

It is one way, yes. I don't know if it's the only way. But it is what you seem to be attempting to do - you are just doing it wrong. The page in the wiki I linked to gives a step by step example of running xclock in the way you want.
