I recently needed to whitelist some Microsoft service addresses. I found the following information containing the Microsoft IP space for services.
Exchange Online Protection IP Addresses – technet.microsoft.com/en-us/library/dn16…
Monitoring a Linux process by PID and sending a e-mail notification upon failure
One of my clients needs their vendor to be alerted when their Backup Exec service crashes. I wrote the following quick-n-dirty batch script intended to be ran as a cron job.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 |
#!/bin/bash # Process Monitor # Send e-mail alerts when service goes down # ------------------------------------------------------------------------- # Author: Nathan Riley # ------------------------------------------------------------------------- SUBJECT="Backup Exec Agent Failure" EMAIL="address@email.to" EMAILMESSAGE="/tmp/emailalert.txt" #path to pgrep command PGREP="/usr/bin/pgrep" # Daemon name, DAEMON="httpd" # find daemon pid $PGREP ${DAEMON} if [ $? -ne 0 ] # if daemon not running then # Generate email message body echo "This is servername at location. The Backup Exec service is no longer running." > $EMAILMESSAGE # send email alert /usr/bin/mail -s "$SUBJECT" "$EMAIL" < $EMAILMESSAGE fi |
And the cron line would be something like this:

*/5 * * * * root /root/restart.sh >/dev/null 2>&1 |
Removing MX records from a Microsoft DNS Server via script
We recently switched our barracuda system from using two equally weighted MX records to using one MX record that points to two same-named A records. We are hoping that this will help better load balance the Barracuda cluster. I wrote a quick-n-dirty batch script to remove the second barracuda MX record from our DNS zones:
for /f %%h in (domains.txt) do dnscmd /RecordDelete %%h @ MX 10 servername.net /f
This script takes the input file domains.txt and processes each domain contained in the text file. The format is one domain per line…
ListServ Systems
Need to find a mass mail system that we can resell to our clients. This is for replacing ConstantContact.
My Top packages:
- OpenEMM – www.openemm.org/
- DadaMail dadamailproject.com/
I am really leaning towards OpenEMM — these docs are about installing:
