.SH DESCRIPTION
.I Ipconfig
configures an Internet connection on an Ethernet.
The options are
.TP
.B a
do not start 
.I arpd
.TP
.B b
do not use
.SM BOOTP 
to discover a gateway address
.TP
.B p
start
.I arpd
in promiscuous mode (see below)
.TP
.B e
use the Ethernet mounted at
.BI /net/ etherdev
.TP
.B m
set the network mask to
.I ip-mask
.LP
If
.I ipaddr
is specified on the command line, use that instead of
one found in the local database or via the
.SM BOOTP
protocol.
.PP
.I Arpd
performs the Internet Address Resolution Protocol, translating
Internet addresses into Ethernet addresses.
It is normally started by
.IR ipconfig .
The options are
.TP
.B d
print debugging to standard output
.TP
.B p
(promiscuous)
answer ARP
requests for any recognized machine.
The default is to answer just for the machine running
.IR arpd .
.TP
.B e
use the Ethernet mounted at
.BI /net/ etherdev
.TP
.B b
use the IP broadcast address
.I bcast-addr
instead of the correct one.
.PP
.I Rip
runs the routing protocol RIP.
It listens for RIP packets on connected networks and
updates the kernel routing tables.
The only option,
.BR -b ,
broadcasts routing information onto the networks.
