Powershell Script to Test SMTPReading Time: < 1 minute
This one is going to be short and sweet, I’ve been testing SMTP with and without encryption and wanted a good script for that.
Here are the lines that you’ll want to look at configuring:
- Line 5: “$smtpServer =”InsertYourSmtpServerHere”
- Line 12: Change the $false value to $true if you want to encrypt your SMTP with SSL
- Line 13: If you’re using a non-default SMTP port, change the “25” to whatever you’re using
- Line 15: Only change this if you need to enter credentials for authentication
- Line 18/19: Change these to who you want to say the email is from, and to whom it is being delivered.
- Line 21: Change this to whatever you want your email title to be
- Line 25: Change this to say whatever you want the body of the email to say
There are also some write-host’s in there to let you know the values that are being run and whether or not they were successful, which will print to the powershell console.
Wireshark not equal to filterReading Time: < 1 minute
I came across this today and thought I’d share this helpful little wireshark capture filter. Based on wireshark’s documentation if you use
“ip.addr != 10.10.10.10” that should show you everything except for packets with the IP addrress 10.10.10.10. The problem is … it doesn’t work. It turns yellow like this, and doesn’t filter that IP.
The trick is to negate the whole statement, then it will work. Instead of doing “ip.addr!=10.10.10.10” run “!ip.addr==10.10.10.10”. Wireshark then is able to read it as NOT ip equal to, instead of IP is not equal to. Once you do that, you’re golden (well, green).
Simple enough, and it works with any statement — IE if you RDP into a machine and run a capture you should probably include “!tcp==3389” somewhere in your filter statement.
I hope I’ve made your day, at least a little bit easier!
