MAC adresa

MAC naslov je naslov ki ga ima omrežna kartica. Sestavljen je iz številke proizvajalca in serijske številke kartice. Torej ga ni mogoče spreminjati.
Pomnim le enega uporabnega načina rešitve problema:
Svojo mrežno vtakni v prijateljevo mašino, in se poveži prek nje.

v windowsih se da spoolat MAC brez problema, poglej MAC adreso karice in jo poišči v registru, nato na to mesto vpiši "tvojo" MAC adreso

MAC addresso lahko seveda brez problema menjas.

uporabi ukaz arp v command line-u

C:\Documents and Settings>arp

Displays and modifies the IP-to-Physical address translation tables used by
address resolution protocol (ARP).

ARP -s inet_addr eth_addr [if_addr]
ARP -d inet_addr [if_addr]
ARP -a [inet_addr] [-N if_addr]

-a Displays current ARP entries by interrogating the current
protocol data. If inet_addr is specified, the IP and Physical
addresses for only the specified computer are displayed. If
more than one network interface uses ARP, entries for each ARP
table are displayed.
-g Same as -a.
inet_addr Specifies an internet address.
-N if_addr Displays the ARP entries for the network interface specified
by if_addr.
-d Deletes the host specified by inet_addr. inet_addr may be
wildcarded with * to delete all hosts.
-s Adds the host and associates the Internet address inet_addr
with the Physical address eth_addr. The Physical address is
given as 6 hexadecimal bytes separated by hyphens. The entry
is permanent.
eth_addr Specifies a physical address.
if_addr If present, this specifies the Internet address of the
interface whose address translation table should be modified.
If not present, the first applicable interface will be used.
Example:
> arp -s 157.55.85.212 00-aa-00-62-c6-09 .... Adds a static entry.
> arp -a .... Displays the arp table.


No najprej si izpises MAC naslove

C:\Documents and Settings>arp -a

Interface: 192.168.0.1 --- 0x10003
Internet Address Physical Address Type
192.168.0.100 00-80-48-d8-1f-22 dynamic
192.168.0.101 00-40-f4-87-d4-2f dynamic


Sedaj pa naredimo zamenjavo in izpisimo rezultat
C:\Documents and Settings>arp -s 192.168.0.100 00-00-00-00-00-00

C:\Documents and Settings>arp -a

Interface: 192.168.0.1 --- 0x10003
Internet Address Physical Address Type
192.168.0.100 00-00-00-00-00-00 static
192.168.0.101 00-40-f4-87-d4-2f dynamic


Tako to gre.

Ne da se vse preko control panela.
To je odvisno od kartice. Ene majo ime taga za properties npr. drugo ime, (ala locally Administered address, Mac addr ipd.), ene tega sploh nimajo, zato je treba v register iti.

3COM to ma, za ostale pa nevem.

Hvala vsem za odgovore.

Kater os pa laufa tale apple?

Če je gor linux bi lahko v konzolo napisal kaj takega:

ifconfig eth0 down
ifconfig eth0 hw ether 00:D1:60:0B:B9:17
ifconfig eth0 up

Sicer se na MacOS X ne spoznam kaj dosti, ampak baje je narejen na BSD jedru, torej bi laho uporabil nekaj takega:

ifconfig xl0 down
ifconfig xl0 link 00:D1:60:0B:B9:17
ifconfig xl0 up

Vsaj mislim, da bi nekaj takega delovalo.
Upam, da se ne motim, če se me naj kakšen popravi prosim, ker nism 100%.
