Re: unix/sockets.
In message <9707241310.AA09684@avoda.jct.ac.il> you write:
|hi, i'd like to get some info or a programme on how to read what
|an other user is writing on his terminal
|i know that i have to open a socket (socket, connect, bind,...
|) and to listen to the packets that are going out from
|his keyboard.
:-) You remind me the guy we cought at HUJI CS one day trying to copy
our Sparc server's /vmunix - he was planning to run it on his PC (that
was way before Linux days...). You can't even use the right terms but
you want to write a sniffer?
|what is the structure of those packets.
Read any of the RFC's which define IPv4 and TCP and the books on the
subject - Steven's "TCP/IP Illustrated" series, especially Volume 1:
"The protocols", is my recommandation.
