I was trying to connect to a host on port 10022 and this was consistently not working. When I looked in our SOCKS logs, I saw the connection was being attempted on port 10061 I believe the code in question is https://github.com/sshnet/SSH.NET/blob/develop/src/Renci.SshNet/Session.cs#L2150 10022 / 255 = 0x27 10022 % 255 = 0x4D 0x274D == 10061 != 10022 If I change the port to 9983, then I can trick it into working
