IPCONFIG(8) System Manager's Manual IPCONFIG(8)NAME
ipconfig, arpd, rip - Internet configuration and routing
SYNOPSIS
ip/ipconfig [-abp] [-e etherdev] [-m ip-mask] [ipaddr]
ip/arpd [-pd] [-e etherdev] [-b bcast-addr]
ip/rip [-b]
DESCRIPTION
Ipconfig configures an Internet connection on an Ethernet. The options are
a do not start arpd
b do not use BOOTP to discover a gateway address
p start arpd in promiscuous mode (see below)
e use the Ethernet mounted at /net/etherdev
m set the network mask to ip-mask
If ipaddr is specified on the command line, use that instead of one found in the local database or via the BOOTP protocol.
Arpd performs the Internet Address Resolution Protocol, translating Internet addresses into Ethernet addresses. It is normally started by
ipconfig. The options are
d print debugging to standard output
p (promiscuous) answer ARP requests for any recognized machine. The default is to answer just for the machine running arpd.
e use the Ethernet mounted at /net/etherdev
b use the IP broadcast address bcast-addr instead of the correct one.
Rip runs the routing protocol RIP. It listens for RIP packets on connected networks and updates the kernel routing tables. The only
option, -b, broadcasts routing information onto the networks.

BOOTP(8) System Manager's Manual BOOTP(8)NAME
bootp, rarpd, tftpd - Internet booting
SYNOPSIS
ip/bootp [-d]
ip/rarpd [-d] [-e etherdev]
ip/tftpd [-dr] [-h homedir]
DESCRIPTION
These programs support booting over the Internet. They should all be run on the same server to allow other systems to be booted. Bootp
and tftpd are used to boot everything; rarpd is an extra piece just for Suns.
Bootp passes to Plan 9 systems their IP address, IP mask, default boot file, default file server, default authentication server, and
default gateway. These come from the network database file attributes ip, ipmask, bootf, fs, auth, and ipgw attributes respectively (see
ndb(6) and ndb(8)). The attributes come from the entry for the system, its subnet, and its network with the system entry having prece-
dence, subnet next, and network last. Bootp will answer requests only if it has been specifically targeted or if it has read access to the
boot file for the requester. The -d option causes debugging to be printed to standard output.
Rarpd performs the Reverse Address Resolution Protocol, translating Ethernet addresses into IP addresses. The options are:
d print debugging to standard output
e use the Ethernet mounted at /net/etherdev
Tftpd transfers files to systems that are booting. It runs as user none and can only access files with global read permission. The
options are:
d print debugging to standard output
h change directory to homedir. The default is /lib/tftpd. All requests for files with non-rooted file names are served starting at
this directory with the exception of files of the form xxxxxxxx.SUNyy. These are Sparc kernel boot files where xxxxxxxx is the hex
IP address of the machine requesting the kernel and yy is an architecture identifier. Tftpd looks up the file in the network data-
base using ipinfo (see ndb(2)) and responds with the boot file specified for that particular machine. If no boot file is specified,
the transfer fails. Tftpd supports only octet mode.
r restricts access to only files rooted in the homedir.
