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
