tshark timer limits using Wireshark

Tshark is a command-line tool that is part of the Wireshark network protocol analyzer. It can be used to capture and analyze network traffic in real-time or from a saved capture file.

When using Tshark, you can set timer limits to control how long the capture will run. There are several timer options available, including:

1. -a duration: This option sets the maximum duration of the capture in seconds. For example, to capture traffic for 5 minutes, you can use the following command:

tshark -a duration:300

2. -a packets: This option sets the maximum number of packets to capture. For example, to capture the first 100 packets of traffic, you can use the following command:

tshark -a packets:100

3. -a filesize: This option sets the maximum size of the capture file in megabytes. For example, to capture traffic until the capture file reaches a size of 100MB, you can use the following command:

tshark -a filesize:100

4. -a interval: This option sets the time interval between two successive captures. For example, to capture traffic every 5 seconds, you can use the following command:

tshark -a interval:5

It's important to note that these options are mutually exclusive, which means you can only use one of them at a time. Additionally, if multiple options are set, Tshark will stop capturing when the first limit is reached.
