# executed by udhcpc

|
# parameters: $1 and environment
|
|
# $1 is:
|
|
#
|
|
# deconfig: udhcpc starts, or lease is lost.
|
|
# Environment example: interface=eth0
|
|
#
|
|
# bound: lease is obtained. Environment example:
|
|
# dhcptype=5
|
|
# serverid=172.16.42.102
|
|
# lease=97200
|
|
# interface=eth0
|
|
# ip=172.16.42.177
|
|
# subnet=255.255.255.0
|
|
# mask=24
|
|
# broadcast=172.16.22.255
|
|
# router=172.16.42.98
|
|
# dns=10.34.32.125 10.32.63.5 10.34.255.7 10.11.255.27
|
|
# domain=lab.example.com example.com
|
|
# ntpsrv=10.34.32.125 10.34.255.7
|
|
#
|
|
# renew: lease is renewed. Environment is similar to "bound".
|
|
# The IP address does not change, however, the other DHCP paramaters,
|
|
# such as the default gateway, subnet mask, and dns server may change.
|
|
#
|
|
# nak: udhcpc received a NAK message.
|
|
# Environment example: interface=eth0
|
|
#
|
|
# leasefail: udhcpc cannot obtain a lease (DHCP server not responding, etc).
|
|
# Environment example: interface=eth0
|
|
|
|
# TODO: put $domain into /etc/resolv.conf (thru /var/service/fw)
