I am using telnet to connect to UNIX machines, to execute remote code. I used apache commons net library.

Since telnet is insecure, I made my mind to use SSH.

I am looking for SSH open source library. Is there any such open source SSH java library? I would be using java client to SSH unix machine.

JSch is pretty much the only game in town. The error handling isn't as good as you'd like, but it has broad support for many important features including Kerberos authentication.

There is also the 'ganymed' library . A few year ago I compared the 'jcraft', 'ganymed' and the IBM (not open source but free-ish) libraries. Because of the IBM name, I expected the IBM ssh library to be the best but was disappointed because I kept getting unexplained random exceptions. The 'ganymed' library was easy to use but lacks some sophistication. In my simple non-exhaustive and non-formal test the jcraft product came out best. If you have time then these other products are worth testing but be careful of the IBM licence.

Try jcabi-ssh, which is a very simple and convenient wrapper of JSch
