I'm writing an application that makes connections to SSH servers. It doesn't need anything specific from the server (except running under GNU/Linux). I need SSH servers for running my application tests.

I was wondering, is there some kind of free and open to anyone SSH servers? Maybe it's an idea for a new service :)

  • Nice, though it doesn't seem to have tools like netcat, telnet etc.

    Well nothing is free. Someone has to pay the bills. And $36 for lifetime access is a good deal.

Maybe you can use virtualization like virtualbox ? You can setup a running small linux server quickly this way.


As suggested, better than need internet connection and free 3rd party ssh accounts, get your own. You can get Virtual Machine (VMWare, VBox, Other) for that, and also, if you have an android mobile you can use SSHDroid (free) instead.

And don't forget Cygwin (Linux environment emulation with some package install support). You can set your ssh server built in windows and no need to get entire system (like vm does). A guide (http://docs.oracle.com/cd/E24628_01/install.121/e22624/preinstall_req_cygwin_ssh.htm)
