# dhclient-script for Linux. Dan Halbert, March, 1997.

# Updated for Linux 2.[12] by Brian J. Murrell, January 1999.

|
||||
# networking.
|
||||
|
||||
# Notes:
|
||||
|
||||
# 0. This script is based on the netbsd script supplied with dhcp-970306.
|
||||
|
||||
# 1. ifconfig down apparently deletes all relevant routes and flushes
|
||||
# the arp cache, so this doesn't need to be done explicitly.
|
||||
|
||||
# 2. The alias address handling here has not been tested AT ALL.
|
||||
# I'm just going by the doc of modern Linux ip aliasing, which uses
|
||||
# notations like eth0:0, eth0:1, for each alias.
|
||||
|
||||
# 3. I have to calculate the network address, and calculate the broadcast
|
||||
# address if it is not supplied. This might be much more easily done
|
||||
# by the dhclient C code, and passed on.
|
||||
|
||||
# 4. TIMEOUT not tested. ping has a flag I don't know, and I'm suspicious
|
||||
# of the $1 in its args.
