R help - Nov 2011 - snow package, socketConnection error, SSH, in Windows 7 x64

Hi. I have some problems trying to make cluster via  "snow" package 
and
 haven't found a solution for my problem in archives and relative topics.

I installed ssh server using cygwin and set  a password-less SSH Login.
In R session after starting ssh service:
> system("ssh 10.10.5.15 date")
Tue Nov 22 16:22:36 AST 2011

But when I make connection:
> con <- makeSOCKcluster(rep('10.10.5.15',2), port = 22, master =
'10.10.5.15')
Error in socketConnection(port = port, server = TRUE, blocking = TRUE,  : 
  cannot open the connection
In addition: Warning message:
In socketConnection(port = port, server = TRUE, blocking = TRUE,  :
  port 22 cannot be opened

Firewall is turned off.
