net-ssh

I have a rails app where a user can submit a form and it goes off and connects to a remote server via ssh to call a script. Eventually I plan to use delayed_job or something like that but I can't get it to work in production with even a simple test. The odd thing is, Net::SSH works just fine from the console in production, but it fails with AuthenticationFailed when I submit the form in production. Both the console and the webapp work fine in development. The error: Net::SSH::AuthenticationFailed (my_ssh_username): app/models/branch.rb:69:in `ssh_to_machine' app/controllers/branches_controller

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

I have a snippet of code, simply trying to execute a script on a remote server, in the event that it fails, I'd like to make a follow-up call, imagine this: require 'rubygems' require 'net/ssh' require 'etc' server = 'localhost' Net::SSH.start(server, Etc.getlogin) do |ssh| puts (ssh.exec("true") ? 'Exit Success' : "Exit Failure") puts (ssh.exec("false") ? 'Exit Success' : "Exit Failure") end I would expect (ignoring that stdout and stderr are printed in my contrived example) - but first line should exit with 0 which I would expect Ruby would interperate as false and display "Exit Failure"

Is there any way i can get a login shell in ruby using net-ssh? Is that even possible? By login shell i mean the ones the source /etc/profile.. Net-SSH is too low level to simply provide this up front (the way it is now, anyways). You can check out Net-SSH-Shell which builds upon Net-SSH to add login shell functionality: https://github.com/mitchellh/net-ssh-shell The implementation is solid and works, however I found its not too useful since you can't specifically extract things like stderr or exit status because the commands run in a sub-shell, so you can only get stdout.
