9 <tt/arpd/ is daemon collecting gratuitous ARP information, saving
23 <p> <tt/OPTIONS/ are:
27 <item><tt/-l/ - dump <tt/arpd/ database to stdout and exit. Output consists
30 is replaced by word <tt/FAILED/ followed by colon and time when the fact
33 <item><tt/-f FILE/ - read and load <tt/arpd/ database from <tt/FILE/
34 in text format similar dumped by option <tt/-l/. Exit after load,
35 probably listing resulting database, if option <tt/-l/ is also given.
36 If <tt/FILE/ is <tt/-/, <tt/stdin/ is read to get ARP table.
38 <item><tt/-b DATABASE/ - location of database file. Default location is
39 <tt>/var/lib/arpd/arpd.db</tt>.
41 <item><tt/-a NUMBER/ - <tt/arpd/ not only passively listens ARP on wire, but
42 also send brodcast queries itself. <tt/NUMBER/ is number of such queries
43 to make before destination is considered as dead. When <tt/arpd/ is started
44 as kernel helper (i.e. with <tt/app_solicit/ enabled in <tt/sysctl/
45 or even with option <tt/-k/) without this option and still did not learn enough
49 <item><tt/-k/ - suppress sending broadcast queries by kernel. It takes
50 sense together with option <tt/-a/.
52 <item><tt/-n TIME/ - timeout of negative cache. When resolution fails <tt/arpd/
54 only together with option <tt/-k/. This timeout should not be too much
58 <item><tt/-R RATE/ - maximal steady rate of broadcasts sent by <tt/arpd/
61 <item><tt/-B NUMBER/ - number of broadcasts sent by <tt/arpd/ back to back.
62 Default value is 3. Together with option <tt/-R/ this option allows
63 to police broadcasting not to exceed <tt/B+R*T/ over any interval
64 of time <tt/T/.
68 <p><tt/INTERFACE/ is name of networking inteface to watch.
69 If no interfaces given, <tt/arpd/ monitors all the interfaces.
70 In this case <tt/arpd/ does not adjust <tt/sysctl/ parameters,
71 it is supposed user does this himself after <tt/arpd/ is started.
76 <p> <tt/arpd/ exits gracefully syncing database and restoring adjusted
77 <tt/sysctl/ parameters, when receives <tt/SIGINT/ or <tt/SIGTERM/.
78 <tt/SIGHUP/ syncs database to disk. <tt/SIGUSR1/ sends some statistics
79 to <tt/syslog/. Effect of another signals is undefined, they may corrupt
80 database and leave <tt/sysctl/ parameters in an unpredictable state.
84 <p> In order to <tt/arpd/ be able to serve as ARP resolver, kernel must be
85 compiled with the option <tt/CONFIG_ARPD/ and, in the case when interface list
86 is not given on command line, variable <tt/app_solicit/
87 on interfaces of interest should be set in <tt>/proc/sys/net/ipv4/neigh/*</tt>.
88 If this is not made <tt/arpd/ still collects gratuitous ARP information
94 <item> Start <tt/arpd/ to collect gratuitous ARP, but not messing
114 <item> Completely replace kernel resolution on interfaces <tt/eth0/
115 and <tt/eth1/. In this case kernel still does unicast probing to
117 and made under authority of <tt/arpd/:
123 This is mode which <tt/arpd/ is supposed to work normally.
