When using Chromium as a Kiosk it will not shutdown properly on reboot.  As a result it throws an error every time it restarts.

Here is my fix(This assumes you are using pi as your auto login user):
1. mkdir /home/pi/scripts
2. nano /home/pi/scripts/chromiumcleanup
3. Add the following:
#!/bin/bash
/bin/sed -i ‘s/”exit_type”:”Crashed”/”exit_type”:”Normal”/’ ~/.config/chromium/Default/Preferences
4. ctrl X and Y
5. chmod 755  /home/pi/scripts/chromiumcleanup
6. crontab -e
7. Add the following: @reboot /home/pi/scripts/chromiumcleaner
Make certain to put a new line after the above.  crontab requires an empty line for an EOF.

Reboot and everything should work.

The following command removes the guest account login option in Ubuntu 16.04

sudo sh -c ‘printf “[SeatDefaults]\nallow-guest=false\n” > /etc/lightdm/lightdm.conf.d/50-no-guest.conf’

To automount cifs from linux to windows 2016 you can do the following

//remoteserver/sharename /localserver/foldername cifs credentials=/yourcredfilelocation,iocharset=utf8,sec=ntlmv2,vers=3.0     0    0

Put the following in your credential file.

username=user@domain
password=password

Then you can type the following command:
mount -a

If you receive an code = -22 error there is probably something wrong in the options you picked.

Steps to monitor a website using curl:
1. Create the main script file
2. Create a site list file
3. Create a cron job

1. main scripts
Working directory /home/username/scripts

vi /home/username/scripts/pingmysites

#!/bin/bash

SITESFILE=/home/usernamescripts/servers.txt #list the sites you want to monitor in this file
EMAILS=”[email protected]” #list of email addresses to receive alerts (comma separated)

while read site; do
if [ ! -z “${site}” ]; then
echo $site
checker=$(/bin/ping -c4 $site)

if echo $checker | grep “0 received” > /dev/null
then
echo “The Server on ${site} is down!”

MESSAGE=”This is an alert from MonitorServer that the ping test to the Server ${site} has failed to respond.”

for EMAIL in $(echo $EMAILS | tr “,” ” “); do
SUBJECT=”The ping test to the  Server $site (ICMP) Failed”
echo “$MESSAGE” | mail -s “$SUBJECT” $EMAIL
echo $SUBJECT
echo “Alert sent to $EMAIL”
done
fi
else
echo “The Server on ${site} is up!”

fi
done < $SITESFILE

2. Site list file
Working directory /home/username/scripts

vi /home/username/scripts/servers.txt

192.168.1.7

3. Cron job
crontab -e
