+ # dhclient-script for Linux. Dan Halbert, March, 1997.
+ # Updated for Linux 2.[12] by Brian J. Murrell, January 1999.
+-# No guarantees about this. I'm a novice at the details of Linux
+-# networking.
++
++# Updated to iproute2 by Jim Gifford ([EMAIL PROTECTED])
+
+ # 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.
++# 1. This script was modified to work with iproute2
++# 2. cidr_convert based on a script by Kevin Fleming ([EMAIL PROTECTED])
++# 3. Updated to delete addresses when taking an interface down ([EMAIL
PROTECTED])
