[LARTC] Little script to save and restore ip rules

[Lee Lists <lists@aacom.fr>]

Hello,

I would like to have some testers for this script which should save and 
restore ip rules and associated tables.

Thanks

#!/bin/bash
#
# chkconfig: 2345 85 15
# description: save and restore ip rules settings
# config: /etc/sysconfig/iprules

# source function library
. /etc/rc.d/init.d/functions

CONFIG=/etc/sysconfig/iprules

RETVAL=0

case "$1" in
  save)
    echo -n "Saving ip rules:"
    rm $CONFIG > /dev/null 2>&1
    ip ru ls | grep -v "^3276.:" | grep -v "^0:" | sed -e "s/://" -e 
"s/from all//" -e "s/^/ip ru add preference /" |
        echo $LINE >> $CONFIG
    done
    ip ru ls | grep -v "lookup local" | grep -v "lookup main" | grep -v 
"lookup default" | sed -e "s/^.*lookup //" |
        ip ro ls ta $LINE | sed -e "s/$/ ta $LINE/" -e "s/^/ip ro add /"
