New Post: Command Not found error 127

When we are executing few command the below code is executing successfully but for few commands such as "server_mount ALL" , it is giving error code 127 and command not found error with message "bash: server_mount: command not found"

If we notice carefully the error message does not have ALL text. its only having server_mount . What could be the issue . is the problem with space before ALL

Please suggest a solution.

below is the code i am using I am using dotnet 3.5 latest dll
var client = new SshClient("12.xx.xx.xx", "rootxx", "xxxxx");

        client.Connect();

           string commandName = txtCommand.Text.ToString();
            SshCommand command = client.CreateCommand(commandName);
            command.CommandTimeout = new TimeSpan(24, 0, 0);
            commandResult = command.Execute();
            string error = command.ExitStatus.ToString();
            MessageBox.Show(error);
            MessageBox.Show(command.Error);
