Hi list: I met a problem when made a multicast program.
The problem is that when I send packet to the socket(have join a multicast group) on the linux from hpux 10.2 or windows 2000, the max size of per packet is 28112, though I have set the SO_RCVBUF of socket on the linxu equal to 32768, like this: int bufsize = 32768; int len = sizeof(int); setsockopt(hSocket, SOL_SOCKET, SO_RCVBUF, &bufsize, &len); thanks for helping and hints _______________________________________________ Seawolf-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/seawolf-list
