+#!/bin/bash
+
+#
+# configures aliases of device $1
+#
+# This script goes out of its way to arrive at the configuration of ip
+# aliases described in the ifcfg-$DEV:* and ifcfg-$DEV-range* files from
+# whatever existing configuration it may be given: existing aliases not
+# specified in the configuration will be removed, netmasks and broadcast
+# addrs will be updated on existing aliases, and new aliases will be setup.
+#
+#   range specification files:
+#
+# One can specify ranges of alised ipaddress using ifcfg-$DEV-range* files.
+# Specify multiple ranges using multiple files, such as ifcfg-eth0-range0 and
+# ifcfg-eth0-range1, etc. In these files, the following configuration variables 
+# specify the range:
+#
+#    IPADDR_START    -- ipaddr to start range at. eg "192.168.30.1"
+#    IPADDR_END      -- ipaddr to end range at. eg "192.168.30.254"
+#    CLONENUM_START  -- interface clone number to start using for this range. eg "0"
+#
+# The above example values create the interfaces eth0:0 through eth0:253 using
+# ipaddrs 192.168.30.1 through 192.168.30.254, inclusive.
+#
+# Other configuration variables such as NETMASK and BROADCAST may be specified
+# in the range file and will apply to all of the ipaddresses in the range. Range
+# files also inherit configuration from the ifcfg-$DEV file just like normal.
+#
+# Note that IPADDR_START and IPADR_END are required to be in the same class-c
+# block. I.e. IPADDR_START=192.168.30.1 and IPADDR_END=192.168.31.255 is
+# not valid.
+#
+#   speed with large sets of interfaces:
+#
+# Considerable effort was spent making this script fast. It can efficiently 
+# handle a thousand ip aliases on one interface.
+# 
+# With large sets of ipaddresses the NO_ALIASROUTING=yes configuration is
+# highly recommended. (This can be specified in ifcfg-$DEV and inherited.) This
+# prevents this script from setting up routing details for the virtual
+# interfaces, which I don't think is needed, because outgoing traffic can use the
+# main interface. However, make your own conclusions on what you need.
+# 
+# My test setup of four class C address blocks on a P166 took 25 seconds of 
+# which 16 seconds of this was spent in the ifcconfig calls. Without the 
+# NO_ALIASROUTING=yes config an additional 12 seconds is spent in route calls.
+#
+#   notes on internals:
+#
+# This script uses the bash "eval" command to lookup shell variables with names
+# which are generated from other shell variables. This allows us to, in effect,
+# create hashes using the shell variable namesspace by just including the hash
+# key in the name of the variable.
