VPLS.US

have my own vm with westhost… barilin.com

using cron.

# Updated 2/9/19
2,7,12,17,22,27,32,37,42,47,52,57 * * * * /root/bin/reportipaddress &> /dev/null

I have it running the foloowing every 5 minutes…
pushing the IP Address up to my VM

root@cp1:~/bin# cat reportipaddress
DATE=/usr/bin/date
QUERY=""
QUERY="/usr/bin/curl http://barilin.com/whatipaddressami"
$QUERY
if [ "$QUERY" != "" ]; then
  $ECHO $DATE >> /var/log/reportipaddress.log
fi;
root@cp1:~/bin#

I have it report into my vm and have it query a non exsistant url..
Then I parse the logs every 5 mintues with cron

5,10,15,20,25,30,35,40,45,50,55,59 * * * * ~/bin/5minutes.sh

cron calls a script

[uscopley@sl-508-21 bin]$ cat 5minutes.sh
CAT=/usr/bin/cat
FILE="/home/uscopley/access-logs/barilin.com"
HEADHTML="/home/uscopley/bin/5minutes.head"
TAILHTML="/home/uscopley/bin/5minutes.tail"
GREP=/usr/bin/grep
TAIL="/usr/bin/tail -10"
STRING=whatipaddressami
REPORT="/home/uscopley/www/reportipaddress.html"
#
#
#
$CAT $HEADHTML > $REPORT
$CAT $FILE | $GREP $STRING | $TAIL >> $REPORT
$CAT $TAILHTML >> $REPORT
#
#
#

#cat ~/access-logs/barilin.com | grep whatipaddressami | tail -3 > ~/www/reportipaddress.html

The next part hasn’t been written yet. I’m going to grab that ip address that’s reported
and shove it into dns… With my home A name.

So, I like to have all my pies download a set of configs at boot. Allows me to make a change
a centeralized location and push it out to everyone (When they reboot)

All pies get this in their /etc/rc.d/rc.local

/home/zero/updates/update.sh
#
/etc/sethostalias.sh > /etc/hostalias
#
/usr/sbin/netdate ntp1 >> /home/netdate/n3.netdate.log
#
sleep 20;
/etc/rc.d/rc.ntpd restart
#

and then of course /etc/fstab has a samba mounted share with the following

//cp1/zero      /home/zero      cifs      user=timc,pass=[password]       0   0

and the /home/zero/updates/update.sh has the following

#
#  Setup some variables
#
CP="/usr/bin/cp"
DIR="/home/zero/updates"
MKDIR="/usr/bin/mkdir"
#
#  Updatre aliases and hosts and profiles from CP1
#
$CP $DIR/sethostalias.sh /etc
$CP $DIR/hosts /etc
$CP $DIR/profile /etc
$CP $DIR/alias /etc
#
#  Make a bin directory for root on host
#
EDIR="/root/bin"
if [ ! -d $EDIR ]; then
  $MKDIR $EDIR
  $CP $DIR/bin/ $EDIR
fi
#
#  Couple files for Serial stuff on PI's
#
$CP $DIR/config.txt /root
$CP $DIR/cmdline.txt /root
$CP $DIR/inittab /root
#
# Couple fixes for snmp / ntp
$CP $DIR/rc.M /etc/rc.d/
$CP $DIR/snmpd.conf /etc/snmp/
$CP $DIR/ntp.conf /etc/

with all the appropiate file goodies. This seems to fluctuate based upon what I’m doing…
