No.  xhost is not needed, nor desired, when using ssh.

It is more likely that some of your Linux machines don't have ssh setup 
to allow X11 tunnelling.

Follow the instructions on the following page for ssh, very carefully:

http://xfree86.cygwin.com/docs/ug/using-remote-apps.html

You should not have any trouble if you do it this way... unless your 
Linux machines need to have their sshd configuration changed, which you 
can find documentation about elsewhere.
