You can download the contents of the networkmon.sh script from the downloads section or copy and paste it from here:<\/p>\n
#Update the \"HOSTS\" line with as many domains or IP address you would \r\n#like this script to monitor, separate each with a space.\r\nHOSTS=\"DOMAIN1 DOMAIN2 IPADDR3 IPADDR4\"\r\n# Modify \"COUNT\" to adjust the amount of pings that are sent\r\nCOUNT=1\r\nfor myHost in $HOSTS\r\ndo\r\n count=$(ping -c $COUNT $myHost | grep 'received' | awk -F',' '{ print $2 }' | awk '{ print $1 }')\r\n if [ $count -eq 0 ]; then\r\n # If 100% failed email the address below with the message contents of the file \/root\/mail\/networkdown.txt\r\n echo \"Host : $myHost is down (ping failed) at $(date)\" | ssmtp EMAIL@ADDRESS < \/root\/mail\/networkdown.txt\r\n fi\r\ndone<\/pre>\nI save the above content in \/scripts\/networkmon.sh, but feel free to save it in a more suitable location for your needs. <\/p>\n
Next you need to create the contents of \/root\/mail\/networkdown.txt (again feel free to save this file in a different location and update the file path in the script portion above)<\/p>\n

I use Webmin to make cron jobs, I find it much easier that way.
