Subj: looking for C source for IP Hdr Cksum
Orga: Siemens Transmission Systems, Albuquerque, NM




        Does anyone have the C source code (or algorithm in ENGLISH!)
        for calculating the checksum for the IP PDU header??
        (IP = Internet Protocol - ISO 8473)
        The ISO 8473 annex gives a really wierd description of the 
        cksum algorithm using MODULO 255 arithmetic. HELP! What is 
        that ?????               

        Thanks in advance
