IPCONFIG(8) IPCONFIG(8) NAME ipconfig, dkipconfig, udpconfig - set up DARPA Internet protocols SYNOPSIS /usr/ipc/mgrs/ipconfig [ -m mask ] [ -df ] ip-device localhost network [arp-device] & /usr/ipc/mgrs/dkipconfig gatemachine localhost remotehost & /usr/ipc/mgrs/udpconfig udp-device & DESCRIPTION Ipconfig activates the DARPA Internet protocol on a communi- cations device, with Internet address localhost for the host and network address network for the device. If arp-device is specified, the ARP address resolution pro- tocol is started on that device. Option -d causes ipconfig to print ARP requests on the standard output as they are received. Option -m declares a subnet mask for the network reached through ip-device. Mask may be a four-piece IP address like `255.255.255.0' or a 32-bit hexadecimal number like `ffffff00'. Option -f is a special workaround for networks with obsolete hosts. It causes ipconfig to answer illegal ARP requests for the subnet's broadcast address with an illegal Ethernet address, to prevent broadcast storms. Dkipconfig places a network call to gatemachine and acti- vates the IP protocol on the connection, so that the remote machine becomes a gateway for the caller's IP traffic. Localhost becomes the calling machine's Internet address through this IP interface; remotehost is the Internet address to which local IP packets should be sent to reach the gateway. Ipconfig and dkipconfig record unusual events and errors in log files and Udpconfig activates the UDP datagram protocol on the named udp-device, usually Only one udpconfig is needed for the entire collection of IP networks. These programs are usually run once from rc(8). EXAMPLES The following calls start IP on system fs on the first Interlan Ethernet controller, with ARP active; arrange for IPCONFIG(8) IPCONFIG(8) machine nj/astro/research to pass IP packets to fs; and activate UDP. /usr/ipc/mgrs/ipconfig /dev/il00 fs mh-astro-net /dev/il01 & /usr/ipc/mgrs/dkipconfig nj/astro/research fs-dk research-dk127 & /usr/ipc/mgrs/udpconfig /dev/ipudp & FILES SEE ALSO con(1), qns(7), route(8), tcpmgr(8)
