Cyclic paging script

Let's say that we have an emergency voicemail box where our clients can leave us messages if they have a contract for extended hours or a limited response time contract. Let's also suppose that we have a shitty mobile phone provider, whose signal does no goes higher that 3000ft and is not available too far in wilderness, but we still have those old pagers, able to receive the signal even on top of mount Everest. And let's say that we have a bunch of unfortunate enough bastards on call that are supposed to respond to those calls. Now, every week it's some other poor bastard turn to be on call, but just in case he's not available, we might be force to page the other unfortunates, even when it is not their week of duty. And we page them in order, one after another, until one of them login the web interface of our asterisk server or call the emergency mailbox and acknowledge the message.
This is the script that have to be run from cron every */10 minutes on the asterisk server:

IP Changing notification

Because sometimes the dyndns updater goes to hell, a little crontab script executed every couple of hours it's a life saver:

#!/bin/sh
#
# Send an email message to notify about the external IP.
#

#set a file where we can store the ip
logfile=/var/log/extip
#to whom we send the email
recipient="my_account@provider.tld"
#if we are using an external smtp relay
smtp=relay.smtp.provider.tld
export smtp=$smtp
#put a nice sender address on the email
sender="IP Checker <ipcheck@server.tld>"
#find the name of of this server
HOSTNAME=`hostname -a | cut -f1 -d" "`
# format a nice subject
subj="Change of IP on $HOSTNAME"
#now let's get the external ip
ip=`/usr/bin/lynx -dump 'http://whatismyip.org'`
#and create a message body
mesg="$HOSTNAME IP address on `date  +%a' '%b' '%e' '%H.%M.%S' '%Z' '%Y` is $ip"
#see if the ip has changed
oldip=`cat $logfile`
#or if the last message has been sent more than one week ago
age=`find $logfile -mtime +7`

if [ ! "$oldip" == "$ip" ] || [ ! "$age" == "" ]
then
 #keep the new ip into the logfile
 echo $ip &gt; $logfile
 #send email about it
 echo "$mesg" | mail -r"$sender" -s"$subj" "$recipient"
fi

exit 0

Of course, having an external web server, capable of running a little php script will allow us to replace http://whatismyip.org with our own webserver. The php script is really simple:

<?php
$ip = getenv('REMOTE_ADDR');
#$ip = $_SERVER['REMOTE_ADDR'];
echo '
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
' . $ip . '
</body>
</html>';
?>

AUTOTBACK 3.0

A new version of the backup utility.
This is an evolution of the old AUTOTBACK script.
If the script is called without any command-line parameters it will check if "dialog" is installed on the system and it will start the "semi-graphical" interface, otherwise it will display the "usage parameters" and it will exit.

 The command line parameters are still the same:
$autotback ACTION DIRECTORY ARCHIVE MAIL PRINTER, where
- ACTION is backup or restore
- DIRECTORY represent, in case of ACTION=backup the source (what we will backup), or the destination (where the backup will be restored) when ACTION=restore. The default value is "/".
- ARCHIVE represent the location of backup. It is usually the tape device (by default is /dev/st0), but it can also be a simple file (/mnt/disk/archive_name.cpio - if we use an external drive mounted on /mnt/disk)
 - MAIL represent the email address(es) that will receive the backup report. If more than one email address is required, then, on the command line, those must be surrounded by double quotes ("aa@bb.c dd@ee.f gg@hh.i"). The default emails are "backupreport@xxxxxxxx.com root@localhost"
-PRINTER represents the name of the printer used for the report. The default value is empty. The printer MUST be already installed on the system!

#!/bin/sh
#       @(#) AUTOTBACK 3.4 08/09/12
#
# 08/06/2012 (sorin@xxxxxxxx.com) add pre/post actions, embedd dialog
# 17/10/2011 (sorin@xxxxxxxx.com) modify to use tar
# 18/07/2011 (sorin@xxxxxxxx.com) add the restore section, add command-line parmeters
# 10/08/2010 (sorin@xxxxxxxx.com) autoremove lock after 8hrs and reenable backup. remove hit report
# 28/08/2008 (sorin@xxxxxxxx.com) modified for rhel5. skip /proc /sys /tmp. send mail with the result
# modified 9/14/2000 to provide hit reporting on web site
#
#  Usage: $0 backup /source /dev/destination email@notification.address (printer)
#               if no source nor destination is provided, / will be saved to /dev/st0
#         $0 restore /destination /dev/source email@notification.address (printer)
#  when restore is called, the script  will ask you to select a partial restore
#  by typing a file mask. Just type Enter to do a full restore.
#  if no destination is provided, the restore is performed on / from /dev/st0
#  All the reports and temp files are kept in the /var/autotback directory
#
#
# Exit Codes: 0 - OK
#   1 - [ESC] pressed
#   2 - A lockfile exists
#   3 - Can't create dir (am I root? is it /var mounted rw?)
