| 35 | .SH DESCRIPTION | |
| 36 | The | |
| 37 | .I arp | |
| 38 | program displays and modifies the Internet-to-Ethernet address translation | |
| 39 | tables used by the address resolution protocol ( | |
| 40 | .IR arp (4p)). | |
| 41 | .LP | |
| 42 | With no flags, the program displays the current ARP entry for | |
| 43 | .I hostname. | |
| 44 | With the | |
| 45 | .B -a | |
| 46 | flag, the program displays all of the current ARP entries by reading the table | |
| 47 | from the file | |
| 48 | .I kmem | |
| 49 | (default /dev/kmem) based on the kernel file | |
| 50 | .I vmunix | |
| 51 | (default /vmunix). | |
| 52 | .LP | |
| 53 | With the | |
| 54 | .B -d | |
| 55 | flag, a super-user may delete an entry for the host called | |
| 56 | .I hostname. | |
| 57 | .LP | |
| 58 | The | |
| 59 | .B -s | |
| 60 | flag is given to create an ARP entry for the host called | |
| 61 | .I hostname | |
| 62 | with the Ethernet address | |
| 63 | .I ether_addr. | |
| 64 | The Ethernet address is given as six hex bytes separated by colons. | |
| 65 | The entry will be permanent unless the word | |
| 66 | .B temp | |
| 67 | is given in the command. | |
| 68 | If the word | |
| 69 | .B pub | |
| 70 | is given, the entry will be "published", e.g., this system will | |
| 71 | respond to ARP requests for | |
| 72 | .I hostname | |
| 73 | even though the hostname is not its own. | |
| 74 | .LP | |
| 75 | The | |
| 76 | .B -f | |
| 77 | flag causes the file | |
| 78 | .I filename | |
| 79 | to be read and multiple entries to be set in the ARP tables. Entries | |
| 80 | in the file should be of the form | |
| 81 | .IP | |
| 82 | .I hostname ether_addr | |
| 83 | [ | |
| 84 | .B temp | |
| 85 | ] [ | |
| 86 | .B pub | |
| 87 | ] | |
| 88 | .LP | |
| 89 | with argument meanings as given above. | |
