问题
I've been struggling on this for a few days now..
When I try to call a method in a helper from a view to do ssh, it throws that error.
"This error occurred while loading the following files: net/ssh"
But when I copy the code into a test.rb
file and execute it from prompt ruby test.rb
it connects flawlessly.
What could be the problem ? I tried on another computer and same result.
Thank you very much this is like the last step before I can complete my project!
Regards,
application_helper.rb
:
module ApplicationHelper
def title(value)
unless value.nil?
@title = "#{value} | Eucc"
end
end
def execute
require 'rubygems'
require 'net/ssh'
@hostname = "smtlmon02"
@username = "gcaille"
@password = "qaz1234"
@cmd = "ls -al"
@cmd2 = "sudo su - -c 'ls;date'"
ssh = Net::SSH.start(@hostname, @username, :password => @password)
res = ssh.exec!(@cmd)
res2 = ssh.exec!(@cmd2)
ssh.close
File.open("output.txt", 'w') {|file| file.write(res2)}
end
end

You just need to add it to Gemfile like this:
gem 'net-ssh'
and run bundle install after that.

You may need to restart your IDE as well. I had this problem with Net::SFTP and Sergey Moiseev's solution worked great, but I had to restart my IDE after the bundle install.
