Analyzing an Ftp Connection With Wireshark

By George El. • February 2019 • Reading time: 3 minutes

In this post we will analyze an ftp connection with wireshark. First we see that the client establishes a control connection to port 21 on the server. The server is the one with the public IP address. The RTT time is the difference between SYN and SYN-ACK and is 0.0849. (In order to see the time or delta between displayed packets you have to go to View, Time Display Format, Seconds since previous displayed packet)
