Date: 10 Nov 1993 11:22:40 -0500 Organization: The Thomas Jefferson High School for Science and Technology Lines: 13 Distribution: world Message-ID: <2br4gg$oaa@thor.tjhsst.edu> NNTP-Posting-Host: thor.tjhsst.edu I am trying to write some code that requires raw IP access using the BSD sockets interface. However, I'm having a bit of trouble setting the Type Of Service field in the IP header on the socket. The offending line is: setsockopt(ip_socket, IPPROTO_IP, IP_TOS, (char *)(&protocol_num), sizeof(protocol_num)); This returns EPERM running as the superuser. Could someone suggest a fix for this or what I'm doing wrong? Thanks, -Craig
