libnss pouzivam, (passwords, shadow ide cez LDAP) ale problem je s
"nacitanim" /etc/ethers pri zmene LDAP zaznamov do arp cache jadra. Teda ..
ako spravit arp -f .. po zmene zaznamov v LDAP. Resp. nie je dolezite co je
v /etc/ethers, ale to co kernel ma v arp cache.. Nezda sa mi, ze by jadro
vedelo reagovat na /etc/ethers bez programceku arp .. Ostatne s podporou
/etc/ethers je to  vobec divne, cez to vsetko, ze mam /etc/ethers pomerne
plne (260 zaznamov)  getent ethers nejak nehcodi :( 

# getent ethers
Enumeration not supported on ethers

(tato hlaska mi nejak nic nehovori, arp -f zbehne spravne)

man stranka k arp hovori o /etc/ethers:

The name of the data file is very often /etc/ethers, but this is not
official.

(viac som to nelustil .. )

Pripadne .. existuje arpd s podporou LDAP ? takto by sa dalo priamo drzat
staticky arp z LDAP serveru. 

Idealne by bolo:  LDAP popisuje kazdy komp na sieti (MAC, IP, co  ma
povolene). Ruter cita LDAP pri DHCP poziadavke, vie podla MAC priradit IP,
upravit arp cache jadra, nahodit firewall, squid delay pool atd. 
(mam postacujuci priestor IP, postacuje staticke priradenie MAC-IP).
