Problem with remote host - WeOnlyDo Discussion board

Linear

I have a strange problem with a remote host closing connection sometimes. I'm using the following code:

try
{
SSH ssh = new SSH();
ssh.Hostname = hostname ;
ssh.Login = user ;
ssh.Password = password ;
ssh.TerminalType = tty ;
ssh.Blocking = true;
ssh.Timeout = 0;

ssh.Command = ls -la;echo XXX
;
ssh.Connect();
string data = ssh.WaitFor( XXX );
Trace(data);
}
catch (Exception exc)
{
Trace(exc.Message);
}

Doing this sometimes it works, sometimes I immediately get the exception Remote host has closed the connection . What I'm doing wrong?

Kind regards,
Helmut

Helmut,

it's because you set Command property. When set, it is executed instead of shell, so as soon as that command completes, connection is closed from remote side.

Basically, you have here race condition - what will happen first, will command finish first, or your WaitFor? Obviously, sometimes one wins, sometimes another...

Thank you very much for the rapid responses. I was a little nervous about dealing with a company that is on a different continent from me. You have proven my concerns to be unfounded.

Your component works really great. With minor effort I have been able to convert my delphi application...

We have recently completed a large 1200+ location project where reliable Telnet and SSH connectivity was required. wodSSH worked flawlessly and allowed our staff to complete our project ontime and within budget.
