isConnected

public boolean isConnected()

Description copied from interface: Session

是否连接状态

Specified by:

isConnected in interface Session

Returns:

是否连接状态

close

public void close()
           throws IOException

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Throws:

IOException

bindLocalPort

public void bindLocalPort(InetSocketAddress localAddress,
                          InetSocketAddress remoteAddress)
                   throws IORuntimeException

Description copied from interface: Session

绑定端口到本地。 一个会话可绑定多个端口
当请求localHost:localPort时，通过SSH到服务器，转发请求到remoteHost:remotePort
此方法用于访问本地无法访问但是服务器可以访问的地址，如只有服务器能访问的内网数据库等

Specified by:

bindLocalPort in interface Session

Parameters:

localAddress - 本地主机和端口

remoteAddress - 远程主机和端口

Throws:

IORuntimeException

unBindLocalPort

public void unBindLocalPort(InetSocketAddress localAddress)
                     throws IORuntimeException

Description copied from interface: Session

解除本地端口映射

Specified by:

unBindLocalPort in interface Session

Parameters:

localAddress - 需要解除的本地地址

Throws:

IORuntimeException

bindRemotePort

public void bindRemotePort(InetSocketAddress remoteAddress,
                           InetSocketAddress localAddress)
                    throws IORuntimeException

Description copied from interface: Session

绑定ssh服务端的serverPort端口, 到本地主机的port端口上.
即数据从ssh服务端的serverPort端口, 流经ssh客户端, 达到host:port上.
此方法用于在服务端访问本地资源，如服务器访问本机所在的数据库等。

Specified by:

bindRemotePort in interface Session

Parameters:

remoteAddress - ssh服务端上要被绑定的地址

localAddress - 转发到的本地地址

Throws:

IORuntimeException

unBindRemotePort

public void unBindRemotePort(InetSocketAddress remoteAddress)
                      throws IORuntimeException

Description copied from interface: Session

解除远程端口映射

Specified by:

unBindRemotePort in interface Session

Parameters:

remoteAddress - 需要解除的远程地址和端口

Throws:

IORuntimeException

exec

public String exec(String cmd,
                   Charset charset)

执行Shell命令

Parameters:

cmd - 命令

charset - 发送和读取内容的编码

Returns:

结果
