NAME
rarpc — Reverse Address Resolution Protocol client
SYNOPSIS
rarpc
[-d]
[-e|-s]
[-n
count]
interface_name
DESCRIPTION
rarpc,
the Reverse Address Resolution Protocol client, implements the
client portion of the Reverse Address Resolution Protocol (see
SEE ALSO).
It sends RARP requests for the specified interface's hardware
address and waits for the response from the RARP server.
rarpc
can be used during boot-time initialization to find the IP
address of an interface. To do so, set the
IP_ADDRESS[i]
variable
of interface
i
with
IP_ADDRESS[i]=RARP
in
/etc/rc.config.d/netconf.
Options are:
- -d
Print debugging information.
- -e
Use ethernet encapsulation only.
- -s
Use SNAP encapsulation only.
- -n count
Transmits count requests and waits for each one to time out before
giving up.
- interface_name
Identifies the interface to request information about.
If a response is received, it prints the IP address to its standard
output. This information can be used to configure the interface as
seen in
/sbin/init.d/net.
If a response is not received, the client will
retransmit after 2 seconds, and then after 4 seconds.
After that, retransmissions occur every 8 seconds.
RETURN VALUE
Exit status is 1 if the command fails or no RARP response is received.
Exit status is 0 and the IP address is printed to standard output if
a response is received.
LIMITATIONS
- 1.
The
rarpc
client cannot be run at the same time a
rarpd
daemon is
running on the same interface.
- 2.
The
rarpc
client supports only ethernet, 100VG and FDDI
network interfaces.
