The docs folder contains detailed summaies for each layer in the OSI ISO Reference Model, It also contains the specification for these projects, basically the practical specification.
- Location:
docs/
- HTTP/1.1 with CGI support
- FTP with active/passive modes
- SMTP for email transmission
- POP3 for email retrieval
- LDAP for directory services
- Telnet for remote terminal access
- PROXY for the POP3 client
These implementations are designed for educational purposes and protocol understanding. They may not include production-level security features.
Feel free to explore the notes and practicals to enhance your understanding of the OSI model and its applications in real-world networking scenarios. For any questions or further clarifications, please refer to the contact section in the main repository README file.
