RE: Sockets and Telnet

I thought I was on the right path with this, but am still stuck. Based upon these IAC's, can anyone tell me what I need to send back to just get to a login prompt? No matter what I am sending, I never receive anything back, it just hangs.



Do I need to respond one at a time, or can I respond to all with one write to the socket?



I can find very little on this via google. I would think more folks would have a need to do this. I can think of lots of uses.



Thanks again,



Jon

Hi Jon,

x'FFFD25' = IAC DO AUTHENTICATION
x'FFFB01' = IAC WILL ECHO
x'FFFB03' = IAC WILL SUPPRESS-GO-AHEAD
x'FFFD27' = IAC DO NEW-ENVIRON
x'FFFD1F' = IAC DO NAWS
x'FFFD00' = IAC DO BINARY
x'FFFB00' = IAC WILL BINARY

To understand these, please check out the Telnet-related RFCs. There's
a pretty good collection of links to them on Wikipedia's telnet site
(see the "Related RFCs" section):

http://en.wikipedia.org/wiki/Telnet

This is by no means an exhaustive list of options, however. If your
program receives an option it's not prepared to handle, it should be
able to tell the Telnet server that it won't enable it. Please read the
RFCs (using the same link above) for info on how to interpret these
requests and reply accordingly.
