    Mapare adresa mac la adresa IP

    Buna seara. In Red Hat Enterprise 5.5 am definit o noua clasa de adrese interna pe o interfata de retea. Vreau ca aceste IP-uri sa fie distribuite in functie de adresa MAC, nu vreau ca oricine sa intre in retea. Alocarea se va face static, fara server DHCP. In cazul acesta, care este procedeul de mapare a adresei IP la adresa MAC ? Cu google.ro nu am gasit nimic. Multumesc.

    pai asta:
    -s hostname hw_addr, --set hostname
    Manually create an ARP address mapping entry for host hostname with hardware address set to hw_addr class, but for most classes one can assume that the usual presentation can be used. For the Ethernet class, this is 6 bytes in hexadecimal, separated by colons. When adding proxy arp entries (that is those with the publish flag set a netmask may be specified to proxy arp for entire subnets. This is not good practice, but is supported by older kernels because it can be useful. If the temp flag is not supplied entries will be permanent stored into the ARP cache.
    NOTE: As of kernel 2.2.0 it is no longer possible to set an ARP entry for an entire subnet. Linux instead does automagic proxy arp when a route exists and it is forwarding.
    desi daca as fi in locul tau as baga si reguli in iptables sa asociez mac-ul cu ip-ul.

    Multumesc mult de raspuns. Ce regula ar trebui sa bag in IPTABLES ca sa asociez mac-ul cu ip-ul ?
