<h2>Tips</h2>
|
|
<ul>
|
|
<li>Use live capture vs. reading pcap to compare behavior</li>
|
|
</ul>
|
|
<ul>
|
|
<li>Pipe output with tshark flags into termshark for filtering before loading</li>
|
|
</ul>
|
|
<ul>
|
|
<li>Familiarize with filter syntax early (e.g., ip.src == 1.2.3.4)</li>
|
|
</ul>
|
|
<ul>
|
|
<li>Use keyboard navigation to avoid switching back and forth to mouse</li>
|
|
</ul>
|
|
<ul>
|
|
<li>When working over SSH, using termshark avoids copying large pcap files</li>
|
|
</ul>
|
|
<ul>
|
|
<li>Adjust visible columns and packet details via profiles to reduce noise</li>
|
|
</ul>
|
|
<ul>
|
|
<li>Ensure tshark is installed and up to date, since termshark uses it under the hood</li>
|
|
</ul>
|
|
<ul>
|
|
<li>Use Wireshark-compatible display filters for familiarity</li>
|
|
</ul>
|
|
<ul>
|
|
<li>Profiles allow customizing column layouts and color schemes</li>
|
|
</ul>
