Linux SMS / PC Monitoring Script !

Salam,

This is a script I made just to check if remote PC is ON or OFF, then it can take specific action according to your requirement.

Either Alert you using Echo, EMAIL or SMS. You can modify it according to your need, Below script will send sms

A=`nmap -sP $1 |grep "Nmap done" | awk '{print $6}' | sed "s/(//" | sed "s/1/5/" | sed "s/0/1/"`
 B=`echo $A`
 if [ "$B" == "5" ]; then
 echo "PC is working fine. no need to send SMS"
 else
 #       echo "DOWN"
 echo "POTUS ALERT: PC Down. Please check SERVER Room / zaib " | gnokii --sendsms 03002357367
 echo "POTUS ALERT: PC Down. Please check SERVER Room / zaib " | gnokii --sendsms 03333021909
 #echo $B
 #echo PC Down.
 fi

I used NOKIA 9300i Communicator mobile.

[global]
 port = /dev/ttyACM0
 model = 6230
 initlength = default
 connection = dku2libusb
 use_locking = no
 serial_baudrate = 19200
 smsc_timeout = 10
 [xgnokii]
 allow_breakage = 0
 TELEPHONE = 03333021909
 debug = on
 rlpdebug = off
 xdebug = off
 [phone_fake]
 port = foobar
 model = fake
 connection = serial

SCRIPT TO CHECK SQUID STATUS AND START IT IF REQUIRED.

Following script will check SQUID service status , and if it found squid stop, it will start it auto, if the squid is already running , it will do nothing 🙂

"s/1/5/" | sed "s/0/1/"`
A=`service squid status | awk '{print $3}' | sed "s/process/5/"`
B=`echo $A`
if [ "$B" == "5" ]; then
echo "SQUID is working fine. Zaib"
else
#       echo "DOWN"
echo "SQUID Down, starting SQUID"
service squid start
fi

You can create its cron entry to run it after every 5 minutes.

For example, add it using CRON by following

crontab -e

and add following line

*/5 * * * * /etc/checksquid.sh

Now save and exit.
