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

[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)

This is an interactive Java(TM) shell, type in Java(TM)
statements to get them executed.

Type in Ctrl^D to logout.

Type in ? or help for a list of available commands.

Type in

Use UP/DOWN arrow keys for command history.

Here you are in the demo shell.

There are two demo built-in commands: 'msg' and 'msgs',
and one built-in field: 'msgs', those are added by this demo.

Try them out and write your own shell similarly.

The following built-in methods:

void javap(Object o); void javap(Object o,int depth);
can be used to examine the structure of any Java class (of an
