Port setting (wodSSH / wodSSH.NET)

by Luis Llorens, Wednesday, August 16, 2023, 21:50 (254 days ago)

I am having a problem with the wodSSH.Port setting. Our configuration changed from Port #22 to Port #2222 and now the wodSSH client does not connect. I did some Wireshark captures and we see that the port # never changes, it is always 22. Seems like it never worked since i was always using port #22.

Any ideas?

Here is the setup:

wodSSH.Login = user;
wodSSH.Password = pass;
wodSSH.Hostname = host;
wodSSH.Port = "2222";
wodSSH.Timeout = "10000";
wodSSH.Blocking = "1";
wodSSH.Protocol = "4";
wodSSH.Command = command;

wodSSH.Connect();

Here is the Wireshark capture of the failure:
