RE: Sockets and Telnet

Ok, I got pulled off of this a while back and am trying to get something going again.



I found this on a systeminetwork.com forum from Scott from 2005. I have 2 different servers I am talking to and the first one is sending this back exactly, I am not sure what kind it is, but I can answer these negotiation requests.



x'FFFD18' = IAC DO TERMINAL-TYPE
x'FFFD20' = IAC DO TERMINAL-SPEED
x'FFFD23' = IAC DO X-DISPLAY-LOCATION
x'FFFD24' = IAC DO ENVIRON



The second is a Microsoft telnet server and I am not sure what these mean. Any ideas?



x'FFFD25'

x'FFFB01'

x'FFFB03'

x'FFFD27'

x'FFFD1F'

x'FFFD00'

x'FFFB00'


Thanks in advance,

Jon

Hi Jon,

Can you post the options that the server requested, and your programs
responses? Also, the options that you requested, and the servers responses?

Preferably with hex values...

Thanks!

Actually it is DOS commands to talk to a Cisco Cable Modem

was somewhat expecting to get a login screen back in my program that
I could issue commands similar to TNAPI, when you look at the log
file.

I am trying two different approaches. Modifying TNAPI and modifying a
socket program that I have been using to talk to a Unix box for quite
some time, that I wrote using examples from your socket tutorial.
But, with either option, I don't seem to be getting anything

intelligible back.
