2026 TryHackMe | Network Security - Protocol and Server | Walkthrough

Описание: 💬 Protocol Deep Dives:
1. Telnet & SSH: Comparing the insecure legacy of Telnet with the encrypted security of Secure Shell.
2. HTTP: Manually fetching web pages using GET requests and understanding the Host header.
3. FTP: Navigating file structures and understanding the difference between Active and Passive modes.
4. Email Protocols: A look at how SMTP sends mail and how POP3/IMAP retrieve it from the server.
5. Wireshark Analysis: Seeing exactly how these protocols look when captured "in the wire" as cleartext.

In this 2026 TryHackMe | Protocols and Servers walkthrough, we shift our focus from scanning ports to understanding the actual conversations happening between clients and servers. This room is a deep dive into the "language" of the internet, stripping away modern GUIs to show you how data is truly exchanged.

We demonstrate how to use Telnet as a manual client to "talk" directly to various services. By manually typing commands for HTTP, FTP, and SMTP, you'll gain a fundamental understanding of how cleartext protocols work and, more importantly, why they are so vulnerable to interception and sniffing.
