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

92 | .B temp | |
