rarpd: add new recipe
RARP (Reverse Address Resolution Protocol) is a protocol which allows individual devices on an IP network to get their own IP addresses from the RARP server. Some machines (e.g. SPARC boxes) use this protocol instead of e.g. DHCP to query their IP addresses during network bootup. Linux kernels up to 2.2 used to provide a kernel daemon for this service,but since 2.3 kernels it is served by this userland daemon. You should install rarpd if you want to set up a RARP server on your network. Signed-off-by: Li Xin <lixin.fnst@cn.fujitsu.com> Signed-off-by: Martin Jansa <Martin.Jansa@gmail.com>

18+.TH RARP 8 "7 April 2000" "rarpd" "Linux Programmer's Manual"
19+.SH NAME
20+rarpd \- Reverse Address Resolution Protocol (RARP) daemon
21+.SH SYNOPSIS
22+.B "rarpd [-aAvde] [-b bootdir ] [ interface ]"
23+.SH DESCRIPTION
24+.B Rarpd
25+is a daemon which responds to RARP requests.
26+RARP is used by some machines at boot time to discover their IP address.
27+They provide their Ethernet address and
28+.B rarpd
29+responds with their IP address if it finds it in the ethers database
30+(either
31+.I /etc/ethers
32+file or NIS+ lookup) and using DNS lookup if ethers database
33+contains a hostname and not an IP address.
34+By default
35+.B rarpd
36+also checks if a bootable image with a name starting with the IP address
37+in hexadecimal uppercase letters is present in the TFTP boot directory
38+(usually
39+.I /tftpboot
40+) before it decides to respond to the RARP request.
41+.SH OPTIONS
42+.TP
43+.B \-a
44+Do not bind to the interface.
45+.TP
46+.B \-A
47+Respond to ARP as well as RARP requests.
48+.TP
49+.B \-v
50+Tell the user what is going on by being verbose.
51+.TP
52+.B \-d
53+Debugging mode. Do not detach from the tty.
54+.TP
55+.B \-e
56+Skip the check for bootable image in the TFTP boot directory. If not
57+present, then even if the Ethernet address is present in
58+the ethers database but the bootable image for the resolved IP does not exist,
59+.B rarpd
60+will not respond to the request.
61+.TP
62+.B "\-b bootdir"
63+Use
64+.I bootdir
65+instead of the default
66+.I /tftpboot
67+as the TFTP boot directory for bootable image checks.
68+.SH OBSOLETES
69+This
70+.B rarpd
71+obsoletes kernel
72+.B rarp
73+daemon present in Linux kernels up to 2.2 which was controlled by the
74+rarp(8) command.
75+.SH FILES
76+.I /etc/ethers,
77+.br
78+.I /etc/nsswitch.conf,
79+.br
80+.I /tftpboot
81+.SH SEE ALSO
82+ethers(5)

1SUMMARY = "The RARP daemon."
2DESCRIPTION = "RARP (Reverse Address Resolution Protocol) is a protocol which \
3allows individual devices on an IP network to get their own IP addresses from \
4the RARP server. Some machines (e.g. SPARC boxes) use this protocol instead \
5of e.g. DHCP to query their IP addresses during network bootup. \
6Linux kernels up to 2.2 used to provide a kernel daemon for this service, \
7but since 2.3 kernels it is served by this userland daemon. \
8You should install rarpd if you want to set up a RARP server on your \
9network."
