48 | .SH DESCRIPTION | |
49 | The | |
50 | .I arp | |
51 | program displays and modifies the Internet-to-Ethernet address translation | |
1350878a MK |
52 | tables used by the address resolution protocol |
53 | .RI ( arp (4p)). | |
55270cae KM |
54 | .LP |
55 | With no flags, the program displays the current ARP entry for | |
56 | .I hostname. | |
1350878a MK |
57 | The host may be specified by name or by number, |
58 | using Internet dot notation. | |
55270cae KM |
59 | With the |
60 | .B -a | |
61 | flag, the program displays all of the current ARP entries by reading the table | |
62 | from the file | |
63 | .I kmem | |
64 | (default /dev/kmem) based on the kernel file | |
65 | .I vmunix | |
66 | (default /vmunix). | |
67 | .LP | |
68 | With the | |
69 | .B -d | |
70 | flag, a super-user may delete an entry for the host called | |
71 | .I hostname. | |
72 | .LP | |
73 | The | |
74 | .B -s | |
75 | flag is given to create an ARP entry for the host called | |
76 | .I hostname | |
77 | with the Ethernet address | |
78 | .I ether_addr. | |
79 | The Ethernet address is given as six hex bytes separated by colons. | |
80 | The entry will be permanent unless the word | |
81 | .B temp | |
82 | is given in the command. | |
83 | If the word | |
84 | .B pub | |
1350878a MK |
85 | is given, the entry will be "published"; i.e., this system will |
86 | act as an ARP server, | |
87 | responding to requests for | |
55270cae | 88 | .I hostname |
1350878a MK |
89 | even though the host address is not its own. |
90 | The word | |
91 | .B trail | |
92 | indicates that trailer encapsulations may be sent to this host. | |
55270cae KM |
93 | .LP |
94 | The | |
95 | .B -f | |
96 | flag causes the file | |
97 | .I filename | |
98 | to be read and multiple entries to be set in the ARP tables. Entries | |
99 | in the file should be of the form | |
100 | .IP | |
101 | .I hostname ether_addr | |
102 | [ | |
103 | .B temp | |
104 | ] [ | |
