Hello - I am trying to connect to a remote solaris box from a solaris box i have locally present with me using 'ssh login@IP' ... Its connecting fine but... when I run xclock - it says 'Can't open display'

Whereas, IF I connect to same remote solaris IP from my windows desktop locally via putty and running xming. xclock works fine.

Please let me know how to run xclock as I can not have xming on local solaris certainly.

Thank you!
