ConoHaの /etc/dhcp/dhclient-exit-hooks が天然記念物のような環境では動かないことがあるので修正版を作ってみた

dhclient-exit-hooks

#!/bin/bash

FIRST=$(/sbin/ifconfig eth0|grep -i global|head -n 1|cut -d ":" -f2,3,4,5)
SECOND=$(/sbin/ifconfig eth0|grep -i global|head -n 1|cut -d ":" -f6,7,8,9|cut -d "/" -f1)

if [ -z "${FIRST}" -o -z "${SECOND}" ]; then
	exit 0
fi

case "${SECOND}" in
	a[0-9]* ) exit 0
esac

IPV6=${FIRST}:a${SECOND}

for SUFFIX in `echo {0..9}`
do
	ifconfig eth0 inet6 add ${IPV6}${SUFFIX}/64
done

for SUFFIX in `echo {a..f}`
do
	ifconfig eth0 inet6 add ${IPV6}${SUFFIX}/64
done

exit 0
