问题 I am using Net-ssh to launch a remote Python script. The Ruby script seems to hang and never complete when the Python script takes a long time to execute (around 20 minutes). I have tested the script by running it directly and it completes without any error. Also everything works fine when the script is executed in a shorter amount of time. This is an extract of the code I am using: (0..(@number_of_vms - 1)).each_with_index do |vm, i| threads << Thread.new do Net::SSH.start('ip-address-vm',

问题 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

问题 I'm working on a Ruby/Rack application that needs to generate SSH keypairs. As much as I'd like to call ssh-keygen from the application, I can't because it's designed to run on Heroku and they don't support calling that command. I've been able to get private/public RSA keys using OpenSSL in the Ruby standard library doing the following: key = OpenSSL::PKey::RSA.generate(2048) # => -----BEGIN RSA PRIVATE KEY----- .... key.public_key # => -----BEGIN RSA PUBLIC KEY----- .... Unfortunately an RSA

问题 I'm attempting to establish a tunnel to a remote server via ssh, and then use the forwarded port to access MySQL. I'm using it currently like this $gateway = Net::SSH::Gateway.new('target.server', 'user') def with_gateway $gateway.open("target.server", 3306) do |port| yield port end end Which in my mind would be similar to this... `ssh -L #{port}:localhost:3306 -N user@target.server` Then when I try to use it and do something like this. with_gateway do |port| puts `mysql -u user -ppass -h 127

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 :

问题 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.. 回答1: 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
