How I use Wireshark - Julia Evans
I use this to run Wireshark on local desktop with live traffic from remote server
e.g. excludes port 22/53

ssh root@host tcpdump -U -s0 'not port 22 and not port 53' -w - | wireshark -k -I -

> Wireshark makes it really easy to look at the lifetime of a TCP connection and see what happened!

> You can do that by right clicking on a packet and clicking “Conversation filter” -> “TCP”.

If you click ‘Statistics’ in the menu then ‘Conversations’, Wireshark will give you this amazing statistics view that looks like this:



This shows me the duration of every single TCP connection, so I can find the long ones and then investigate them in more detail! So useful :D
