c# - SharpSsh Command Execution -

i trying create ssh client using c#. using tamir.sharpssh library. having issues sending command , getting appropriate response server.

the way have been testing sending on ls command, followed cd.. command, followed ls command again -- see whether or not cd.. command being executed properly. however, there no difference between first ls command , second ls command. not entirely sure doing wrong. perhaps using wrong ssh type. have provided code , output getting. have added output expect.

using tamir.sharpssh;  namespace sshnetexample {     class program     {         static void main(string[] args)         {             sshexec ssh = null;             try             {                 console.write("-connecting...");                 ssh = new sshexec(host, username, password);                  ssh.connect();                  console.writeline("ok ({0}/{1})", ssh.cipher, ssh.mac);                 console.writeline("server version={0}, client version={1}", ssh.serverversion, ssh.clientversion);                 console.writeline("-use 'exit' command disconnect.");                 console.writeline();                  while(true)                 {                     string command = console.readline();                      if(command == "exit")                         break;                     string data = ssh.runcommand(command);                      console.writeline(data);                 }             }             catch(exception e)             {                 console.writeline(e.message);             }              if(ssh != null)             {                 console.writeline("disconnecting...");                 ssh.close();                 console.writeline("ok");             }         }     } } 

output:

expected output:

the sshexec class executing single command. logs server each command, , executes command asked to. it's similar (but not same) logging in, typing cd .., logging out again, logging in again , typing ls - when logged in second time redirected home directory.

if want continue use sshexec, should combine commands can execute single command. in instance, example, execute ls ...

if want able issue multiple commands interactive session, @ sshshell class instead of sshexec.
