Error while opening SSH


#1

I am new to ruby. I was planning to automate some deployment processes
and ruby scripts seem to provide an excellent medium to achieve the
same. I am trying to start an SSH session and I get following error
shown below. I tried the solution provided at
http://www.mail-archive.com/removed_email_address@domain.invalid/msg01108.html. I
added the NI_NUMERICSERV flag while getting the IP address in session.rb
file as suggested in the post. But am still gettting the error. Am I
missing anything here?

Thanks
Mahesh
