NOTICE:

While starting to organize this repository and look for features which need to be implemented I stumbled upon the JSch library: http://www.jcraft.com/jsch/. My intentions for this library was to use it for Jython as a drop in replacement for paramiko. However, I realized that even if I wrapped JSch or implemented methods to make jaramiko a "drop in" replacement for paramiko it would never be truly a drop in replacement because I would still need to handle the Java-Python differences in a Python wrapper (a smaller one, but it would still have to be created and maintained). With this in mind I have decided I would not contribute to this repository anymore, but instead suggest you use the JSch library (It is already being used by Apache Ant and Eclipse amongst others). Instead, I will likely be working on trying to make a paramiko branch which is compatible with Jython.

version 2.0beta (May 23, 2011)

• forking Robey's code on github
• cleaning up source files
• cleaning up build file and straightening build locations
• moving to java 1.5
• changing versioning system - all old releases can be considered 1.x where x is the old number they were using (Old releases were released by minor version)
• added an sftp patch found on the internet (still pending testing)

What

Jaramiko is a java port of paramiko, an SSH library for python. It's released under the MIT license, which basically means you can do what you want with it, but you can't take credit for it.

Java and python have different attitudes and styles, so the port is not always literal [*]. In many cases, the API was changed in jaramiko to make it fit more with java's style. (For example, derivatives of InputStream and OutputStream are used instead of fake file descriptors.)

[*]

This is likely going to change: Public API is not going to be broken other than the restriction due to using typed generics which have already been committed, but making jaramiko a drop in replacement for paramiko on Jython would be a great thing for the adoption of Jython (and the use of fabric and boto + other libraries which utilize paramiko on Jython)

Requirements

• Java 1.5+
• a JCE implementation, or some sort of basic crypto library

Jaramiko uses an abstracted interface to access crypto functionality, so you can substitute your own crypto library by writing a glue class. The crypto interface is called CRAI and lives in package net.lag.crai.

Building and Installing

To compile jaramiko, you only need to do:

$ ant build

which will build the libraries in bin/classes. There are some extensive unit tests, which you can run with:

$ ant test

To build the jar run:

$ ant jar

which will create the jar: dist/jaramiko-${VERSION}.jar. Adding this jar to your applications' class path should suffice because there are no other dependencies.

Usage

There are extensive javadocs, which can be built with:

$ ant doc

A good place to start is the Transport class, which handles the actual SSH connection to a remote host.

There's a small demo included in the demo/ folder, which will connect to a server, authenticate, execute a shell command or sftp a file, and display the output. It prompts you for the info it needs. You can build and run it with:

$ ant demo
