I'm wondering what UNIX servers send you when you log on. I wrote an WinSock program that connects to a UNIX (AIX) server. When I connect, it sends me three bytes:
FF FD 18
I didn't know what to do so I just echoed them back and it sent me three more bytes:
FF FC 18
So I echoed those back as well.
This was good in that it got me the login string but that string was preceded with about ten bytes of non-ASCII characters.
It was a wild guess that got me to the login prompt but I'd like to know what all of this non-ASCII data represents, I was expecting to just get a bunch of strings, carriage returns, and line-feeds...
This is my first socket program.
I have no experience in sockets or programming for networks, just a lot of reading.
