—
simple dhcp client for rump kernels
rump.dhcpclient |
ifname |
The rump.dhcpclient
utility is a very
simple DHCP client which can be used to apply networking configuration on
one interface in a rump kernel. Unlike full DHCP clients,
rump.dhcpclient
does not store leases or renew
expired leases. The reason for this is the typical transient nature of a
rump kernel. Additionally, rump.dhcpclient
does not
save DNS resolver information.
After having successfully configured networking,
rump.dhcpclient
prints out the networking
configuration and lease time and exits.
Since rump.dhcpclient
uses
bpf(4) to send and receive raw
network packets, the server must include support for bpf and vfs (for
opening /dev/bpf). Otherwise, the following
diagnostic message is printed:
rump.dhcpclient: bpf: Function not implemented
There is no easy way to release a lease.
