To time dhclient creates a new dhclient.leases file from its in-core lease database. In order to prevent the file from becoming arbitrarily large, from time When a new lease is acquired, it is appended to the end of the dhclient.leases file. On startup, after reading the nf file, dhclient reads the dhclient.leases file to refresh its memory about what In order to keep track of leases across system reboots and server restarts, dhclient keeps a list of leases it has been assigned in theĭhclient.leases(5) file. For each interface, it attempts to configure the interface using the DHCP protocol. It then gets a list of all the network interfaces that are configured in On startup, dhclient reads the nf for configuration instructions. Whereby a client can learn important details about the network to which it is attached, such as the location of a default router, the location of a name The DHCP protocol also provides a mechanism A DHCPĬlient may request an address from this pool, and then use it on a temporary basis for communication on network. The DHCP protocol allows a host to contact a central server which maintains a list of IP addresses which may be assigned on one or more subnets. More network interfaces using the Dynamic Host Configuration Protocol, BOOTP protocol, or if these protocols fail, by statically assigning an address. The Internet Systems Consortium DHCP Client, dhclient, provides a means for configuring one or
