Hvordan kan man gøre det?

Ja, det skulle nok være muligt .. ARP/RARP-protokollen gør vist nok dette (er ikke helt sikker)..

Der en kommando der hedder ARP, måske du kan bruge denne til noget ??

Arp
Displays and modifies the IP-to-Ethernet or token ring physical address translation tables used by the Address Resolution Protocol (ARP). This command is available only if the TCP/IP protocol has been installed.

arp -a [inet_addr] [-N [if_addr]]

arp -d inet_addr [if_addr]

arp -s inet_addr ether_addr [if_addr]

Parameters

-a

Displays current ARP entries by querying TCP/IP. If inet_addr is specified, only the IP and physical addresses for the specified computer are displayed.

-g

Identical to -a.

inet_addr

Specifies an IP address in dotted decimal notation.

-N

Displays the ARP entries for the network interface specified by if_addr.

if_addr

Specifies, if present, the IP address of the interface whose address translation table should be modified. If not present, the first applicable interface is used.

-d

Deletes the entry specified by inet_addr.

-s

Adds an entry in the ARP cache to associate the IP address inet_addr with the physical address ether_addr. The physical address is given as 6 hexadecimal bytes separated by hyphens. The IP address is specified using dotted decimal notation. The entry is permanent, that is, it is automatically removed from the cache after the time-out expires.

ether_addr

Specifies a physical address.

---------------------------

Udpluk fra Win2000 hjælp ... physical adress = MAC adress

arp kan du kun bruge hvis du kender IP\'en!

Du kan bruge arp til at se hvilke ipadresser der hører til mac adressen.
Du skal \'liste\' arp tabellen.

LuF

arp -a viser alle ipadresser og deres mac-adresser

Takker, for alle disse svar.
Er der flere commando\'er der har med ip at gøre.

Kan man gør et eller andet, så man ham af netværket, ved en af alle disse commando\'er?
