here is the code i'm using. is this a bug or am i doing something wrong? It errors out at "sh.SendCommand("cd /");"

Rebex.Net.Ssh ssh = new Rebex.Net.Ssh();
ssh.Connect("domain.net");
Rebex.Net.SshPrivateKey key = new Rebex.Net.SshPrivateKey(@"private.ppk", "");
ssh.Login("username", key);

Shell sh = ssh.StartCommand("pwd");

// read all response line-by-line
while (true)
{
    // read a single response line
    string line = sh.ReadLine();

    // a value of null indicates end of response
    if (line == null)
        break;

    // display the line
    Console.WriteLine(line);
}

sh.SendCommand("cd /");

while (true)
{
    // read a single response line
    string line = sh.ReadLine();

    // a value of null indicates end of response
    if (line == null)
        break;

    // display the line
    Console.WriteLine(line);
}

Shell objects started with Ssh.StartCommand don't support running multiple commands. To do that, either call Ssh.StartCommand multiple times (if the commands are independent on each other) or call Ssh.StartShell instead:

Rebex.Net.Ssh ssh = new Rebex.Net.Ssh();
ssh.Connect("domain.net");
Rebex.Net.SshPrivateKey key = new Rebex.Net.SshPrivateKey(@"private.ppk", "");
ssh.Login("username", key);

// start a shell
Shell sh = ssh.StartShell(ShellMode.WellKnownShell);

sh.SendCommand("pwd");

// read all response line-by-line
while (true)
{
    // read a single response line
    string line = sh.ReadLine();

    // a value of null indicates end of response
    if (line == null)
        break;

    // display the line
    Console.WriteLine(line);
}

sh.SendCommand("cd /");

while (true)
{
    // read a single response line
    string line = sh.ReadLine();

    // a value of null indicates end of response
    if (line == null)
        break;

    // display the line
    Console.WriteLine(line);
}
...
