Ganymed SSH-2 for Java

Ganymed SSH-2 for Java is a library that implements the SSH-2 protocol in pure Java (tested on J2SE 1.4.2, 5, and 6). It allows one to connect to SSH servers from within Java programs. It supports SSH sessions (remote command execution and shell access), local and remote port forwarding, local stream forwarding, X11 forwarding, SCP, and SFTP. There are no dependencies on any JCE provider, as all cryptographic functionality is included.

    Release Notes: An important fix was made. Due to the slightly changed semantics of Thread.interrupt() and Object.wait() in JDK 6, the code had to be adapted in several places. You should not use the older build250 on JDK 6, as the Kex and Streamgobbler code may occasionally consume all CPU resources.

      Release Notes: The code is once again maintained by its original author. This release includes all the fixes and improvements that accumulated since 2006: fixes for the default platform character encodings, workarounds for buggy SSHD servers, improved behavior when catching an InterruptedException, support for sending SSH_MSG_IGNORE packets, support for the "none" authentication method, revised SHA-1 code (with optimizations that should more than double speed), fixes for the SFTP code, and many more.
