Dear community,

I tried the net-ssh gem (net-ssh (2.0.2, 1.1.2)) with this little  
program from the net-ssh webpage:

------- begin test.rb  
require ‘rubygems’  
require ‘net/ssh’

Net::SSH.start(“terra”, “osm”, :password =\> “mypass”) do |ssh|  
result = ssh.exec!(“ls -l”)  
puts result  
end  
-----end test.rb

I get the strange output

/users/osm/lib/ruby/gems/1.8/gems/net-ssh-2.0.2/lib/net/ssh/config.rb:  
69:in `load': undefined method`strip’ for nil:NilClass

I can do a ssh to the machine terra in the shell without problems:

ssh osm@terra ls -l

works fine.

Here are some information about my system:

uname -a  
Linux buin2 2.6.5-7.283-ss #4 SMP Fri Sep 28 13:24:48 PDT 2007 x86\_64  
x86\_64 x86\_64 GNU/Linux

ruby --version  
ruby 1.8.6 (2007-09-23 patchlevel 110) [x86\_64-linux]

ruby -ropenssl -e ‘puts OpenSSL::OPENSSL\_VERSION’  
OpenSSL 0.9.7d 17 Mar 2004

Any Hints?

Thanks a lot  
Daniel
