Hello...

I'm actualy programing socket in C under HP Unix. As I must use TELNET
protocol, I'd like to know if someone could tell me what to do.
I mean, I know that I must create a socket, then, use GetHostByName or
inet_addr, then a conect...
But is there some particular thing I must'nt forget ?

I saw, in the specifications I follow, that I have to force BINARY, and
NODELAY, and at the end of the initialisation I must reset a transparancy
flag...

This is not familiar for me... Anyone could help me ?
Does anyone have some exemple of TelNet socket in C that would help me ?

Thx a lot

Chris

The following URL is  about socket programming
http://www.ecst.csuchico.edu/~beej/guide/net/

For an example of telnet, you can check the book "Internetworking with
Tcp/ip Volume 3, Client-server programming and applications, Linux/Posix
sockets version" of Douglas E. Comer and David L. Stevens. It has an example
of Telnet client.

Depending on the terminal capabilities of the server you will connect to,
you may need to check the document for that corresponding terminal
capability ( VT , WYSE , ... )

HTH,

Hello!

I worked with telnet to test my sockets until I got a system where
netcat was preinstalled ^^ You have to be careful with carriage return
( 10+13 ), if you aren't careful, the program will end up in a big mess.
It took me several hours until I realised, that this is the source of
my problems. ( well, MS has never been keen on standards... ).

cheers
