Simon, Thanks for the reply. I wanted to send ICMP packets. Linux does support AF_RAW. This compiles and runs on my linux system. /* * Create the socket. */ if ( (proto = getprotobyname("icmp")) == NULL) err_quit("unknown protocol: icmp"); if ( (sockfd = socket(AF_INET, SOCK_RAW, proto->p_proto)) < 0) err_sys("can't create raw socket"); Dominic.

How do I use raw sockets? According to the documentation I can use AF_RAW. It also refers the user to the implementation in fptools/hslibs/net/SocketPrim.lhs. Do I really need to do this and if so how do I get it?

The SocketPrim library (aka Network.Socket) really only supports AF_INET and AF_UNIX. Many of the other AF_ things are quite system-dependent; eg. Linux doesn't have AF_RAW. The documentation is a bit slack, although it does mention at the top of the Family(..) definition that "your mileage may vary depending on the OS you use". Do you really want a raw socket, or will a datagram (UDP) socket do? If so, you can just pass Datagram as the SocketType argument to SocketPrim.socket.
