Hi there. I have a rather specific problem dealing with the following variables (those of you without any of these can safely go on): We have the Wollongong group's Enhanced TCP/IP Package (WIN-3B) installed on three AT&T 3B2/310 computers here in our department. They are networked with the campus Ethernet connection; and then on out to the world. The problem I have is trying to set the default broadcast address with this particular version of TCP/IP -- the "ifconfig" does _NOT_ support the "broadcast" parameter; thus I am left to programming my own "sockets" utility to change the default broadcast. I have no experience in sockets; however, I have succeeded in opening the socket to perform an ioctl() to the "ni" driver. Each SIOCGIFBRDADDR (for Socket IO Configuration InterFace Get BRoaDcast ADDRess, I assume) fails with the generic "Invalid Argument", errno = 22. Is anyone familiar with this particular package, and its caveats? Has anyone got an easier way to change the broadcast address? This is _quite_ a special interest concern, I'm sure, so just mail me. Thanks in advance! =========================================================================== | Don Ferencz | "All the world's indeed a stage\ | | ferencz@cwsys3.cwru.EDU | And we are merely players\ | | Dept of Systems Engineering | Performers and portrayers" | | Case Wetsren Reserve University | -- Rush | ===========================================================================
