Solution #00004303

                  

Scope:

This solution applies to all Barracuda Networks products.

 

Answer:

You can use custom arguments with the Tcpdump tool on your Barracuda Networks product to gather and filter various network traffic data. Navigate to Advanced > Troubleshooting. Press Begin TCPDump to execute a tcpdump command. This will open a new window displaying the current traffic flowing through the device.

 

To see traffic on a specific port you can use this argument:

-lnxX -s 1524 port <port #>

Example:

-lnxX -s 1524 port 25

If you know the hostname or IP address you want to filter for, you can add the arguments seen in the examples below.

Example:

-lnxX -s 1524 port 25 and host 166.217.100.113

or

 

-lnxX -s 1524 port 25 and host mail.example.com
