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 &
