Snort and MailReport

dales

I'm using the mailreport package to give me a daily snort status update. Sharing the commands in case others want them or have things to add that I missed.

After setting up the mail report to run once per day, I added the following commands

/usr/bin/uptime

/bin/pgrep -l snort

/usr/bin/tail /var/log/snort/*/alert

/usr/bin/sed -n '/^Starting/{h;d;}; H;${x;p;}' /var/log/snort/snort_rules_update.log

The first command shows the system uptime and load average. Second prints snort PID (so I know it's still running). Third command prints any snort alerts that have occurred since the last time I cleared the alert logs. Final command prints the results of the last rule update.

Full output looks like this:

Current report: Daily Report
