Port setting (wodSSH / wodSSH.NET)

by Luis Llorens, Wednesday, August 16, 2023, 21:50 (310 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:

Hi Luis,

can you try to set Port property after you set Protocol property, since setting Protocol property reverts Port to default value for selected protocol?

Hi Jasmine,

Yes, that worked. Thanks for the quick response. For future reference, where can I get descriptions of the setup parameters?

Regards.

Hi.

Can you be more specific about setup parameters? You can consult our help file with all the properties that you can set before/after making the connection.
