# 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.
|
||||
|
||||
# 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.
|
||||
|
||||
# 5. Script refresh in 2017. The aliasing code was too convoluted and needs
|
||||
# to go away. Migrated DHCPv4 script to ip command from iproute2 suite.
|
||||
# This is based on Debian script with some tweaks. ifconfig is no longer
|
||||
# used. Everything is done using ip tool from ip-route2.
|
||||
|
||||
# 'ip' just looks too weird. Also, we now have unit-tests! Those unit-tests
|
||||
# overwirte this line to use a fake ip-echo tool. It's also convenient
|
||||
# if your system holds ip tool in a non-standard location.
|
||||
ip='/sbin/ip'
|
||||
|
||||
# This is a dummy function to prevent shellcheck from complaining about these
|
||||
# variables later in this script. It is not used during normal operation and
|
||||
# should not slow down the execution of this script at all.
|
||||
# If, given the above, it still bothers you, please feel free to delete it.
