This guide shows a simple way to know when someone logged in as root or normal user using SSH. It will send an email alert notification to the specified email address along with the IP address of last login.

  • As root user create ssh_email_alert.sh with the following text:
#!/bin/bash

tmptxt="/tmp/ssh_alert_email.txt"

ip="`who -m | cut -d'(' -f2 | cut -d')' -f1`"

echo "ALERT - SSH Shell Access"  > $tmptxt

echo "" >> $tmptxt
echo "SSH Login:" >> $tmptxt
echo "`who -m`" >> $tmptxt


echo "" >> $tmptxt
echo "IP:" >> $tmptxt
echo "$ip" >> $tmptxt

echo "" >> $tmptxt
echo "Access time:" >> $tmptxt
echo "`date`" >> $tmptxt

echo "" >> $tmptxt
echo "Current sudo:" >> $tmptxt
echo "`whoami`" >> $tmptxt


echo "" >> $tmptxt
echo "Home path:" >> $tmptxt
echo "`pwd`" >> $tmptxt

#cat $tmptxt
cat $tmptxt | mail -s "Alert: SSH Access from $ip" name@domain.com

rm -fr $tmptxt
NOTE: Ensure you replace name@domain.com with your email address.
  • Set execute permissions:
chmod 755 /usr/bin/ssh_email_alert.sh
  • Edit /etc/profile and add this to the bottom of the file:
ssh_email_alert.sh

You should not get an email anytime a user logs into your HDA via Secure Shell.
