6 | # dhclient-script for Linux. Dan Halbert, March, 1997. | |
7 | # Updated for Linux 2.[12] by Brian J. Murrell, January 1999. | |
8 | -# No guarantees about this. I'm a novice at the details of Linux | |
9 | -# networking. | |
10 | ||
11 | # Notes: | |
12 | ||
13 | # 0. This script is based on the netbsd script supplied with dhcp-970306. | |
14 | ||
15 | -# 1. ifconfig down apparently deletes all relevant routes and flushes | |
16 | -# the arp cache, so this doesn't need to be done explicitly. | |
17 | +# 1. This script was modified to work with iproute2 | |
18 | ||
19 | -# 2. The alias address handling here has not been tested AT ALL. | |
20 | -# I'm just going by the doc of modern Linux ip aliasing, which uses | |
21 | -# notations like eth0:0, eth0:1, for each alias. | |
22 | - | |
23 | -# 3. I have to calculate the network address, and calculate the broadcast | |
24 | -# address if it is not supplied. This might be much more easily done | |
25 | -# by the dhclient C code, and passed on. | |
26 | - | |
27 | -# 4. TIMEOUT not tested. ping has a flag I don't know, and I'm suspicious | |
28 | -# of the $1 in its args. | |
