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.
My R sesioninfo:
