BSD License, 需要 JDK 6.0 或者 JRE 6.0 + OpenJDK Javac 运行.
附件为代码包 (请到 http://sjsh.dev.java.net 下载最新代码包, 此处附件以后不再更新)

参照代码包中 demo/src 目录下的示例, 就可以很简单的写成包装自己应用对象的 SSH Server 了

启动演示 SSH Shell Server

Buildfile: build.xml

build:

[java] Now you can login using an SSH client, with:
[java] User Name: sjsh
[java] Private Key: D:\workspace\SecureJSH\SJSH-Demo-Root\home\sjsh\.ssh\id_rsa
[java]
[java] Type in anything to stop:

然后通过任意SSH客户端连接上去:
(注意OpenSSH客户端需要更改 SJSH-Root\home\sjsh\.ssh\id_rsa 的权限属性为 600, 其他客户端不支持PEM格式私钥的需要转换其格式, PuTTY 带的 PUTTYGEN 工具转换比较好用)
