Makes my modem fetch a new IP when I'm blocked from Posterous. Install `sl` for burning trains. Choo choo.

checkblock.sh

#!/bin/bash

while :
do
    curl -o /dev/null --url http://posterous.com/ >/dev/null 2>&1

    rc=$?
    T="$(date +%H:%M:%S)"

    if [[ $rc != 0 ]] ; then
        echo "$T Blocked. Getting new IP..."
        $HOME/rebootrouter.ex >/dev/null 2>&1

        sleep 60 # wait for the reload to complete

        IP=`curl -s http://ifconfig.me/`
        T="$(date +%H:%M:%S)"
        echo "$T Got new IP: $IP"

        echo "$IP" >> iplist.txt
    else
        echo "$T Not blocked, lets go!"
    fi

    sl -a &
    sleep 30
done
