C#版：
添加sharpssh工程Tamir.SharpSSH.dll，sharpSshTest.exe，Org.Mentalis.Security.dll，DiffieHellman.dll
程序：
using System.Threading; using System.Diagnostics; using System.Net; using System.Net.Sockets; using System.Text; using System; using System.Collections; using System.Collections.Generic; using Tamir.SharpSsh; namespace testSSH { class Program { static void Main(string[]args) { String str=ssh_conn("ip","user","password","cmd"); System.Console.Write(str); System.Console.Read(); } public static string ssh_conn(string ip, string root, string pass, string command) { SshStream ssh = new SshStream(ip, root, pass); ssh.Prompt = "#"; ssh.RemoveTerminalEmulationCharacters = true; //Writing to the SSH channel string response = ssh.ReadResponse(); ssh.Write(command); ssh.Flush(); ssh.Write("/n"); //Reading from the SSH channel response = ssh.ReadResponse(); return response; } } }Java 版：
配置构建路径，添加ganymed-ssh2-build251beta1.jar
