Course content

2 sections • 55 lectures • 1h 38m total length

  • FTP and Email Services0:32

    Explore FTP and email services, learn how to install, configure, and test them, and examine their components to understand how to build a functional email service.

  • Topic A: FTP Services0:18

    Explore FTP services and the file transfer protocol, enabling secure storage on a server, user authentication, and controlled uploading or downloading of files within permissions.

  • FTP1:24

    Explore ftp as a server–client file transfer technology and its authentication options, including web content deployment using linux daemons such as W FTPd, Pro FTPd, and Pure-FTPd.

  • Demo - Installing an FTP Server1:01

    Install the ftp daemon by searching for wu-ftpd in the synaptic package manager, run it as a standalone ftp server, and verify it starts after configuration changes.

  • Configuration2:10

    Configure FTP access by managing FTP users and hosts, restricting who can connect, defining accessible directories and files, and using message files for notices.

  • Demo - Configuring the FTP Server2:16

    Explore configuring an ftp server by inspecting ftp users, analyzing proftpd configuration files under etsi, and adjusting anonymous access, banners, and security features such as tls and ldap.

  • Security1:56

    Explore how FTP security uses route jail to contain programs within a root jail, limiting access to only the necessary file system for a safer virtual FTP and email service.

  • Security B2:18

    Configure anonymous ftp within a true jail, restrict access to the directory structure, enforce file security, disable anonymous uploads, and test changes before restarting the daemon for production.

  • FTP Clients1:08

    Learn to connect to ftp servers with a client like file zila. Set the address and port, manage authentication, store connections, and upload or download securely or insecurely.

  • Active Mode1:37

    Active mode ftp has the client contacting the server on port 21, and the server connecting back for data transfer on port 20, requiring firewall access and dynamic port handling.

  • Passive Mode0:47

    Explore how ftp passive mode lets the client connect to a server-provided port, complete the transfer, and still perform authentication; most ftp servers today run in passive mode.

  • Transfer Types1:28

    Explore ftp transfer types, contrasting ascii mode—transferring data as ascii characters using byte codes—with binary mode, which transfers raw bytes without translation, also known as image mode.

  • Demo - Transferring Files with FTP3:03

    Explore transferring files with ftp by anonymously logging in, navigating to the linux logos penguins directory, downloading jpeg and gif files, and using ascii and binary modes to avoid corruption.

  • Secure FTP1:32

    Learn how secure FTP and secure shell encrypt the session to prevent sniffing of data and passwords, using tools like Putty and OpenSSH.

  • SSH Daemon Configuration2:07

    Configure the SSH daemon to enable secure X11 forwarding, agent forwarding, and port forwarding, securing remote access and credentials over an encrypted tunnel.

  • key Generation B1:40

    Learn how public key encryption uses public and private keys, the role of certificate authorities, and why self-signed keys lack verifiable identity.

  • Key Generation2:16

    Explore key generation concepts by contrasting symmetric and asymmetric keys, explain public key encryption and session key exchange, and review RSA, Diffie-Hellman, and DSA key pairs.

  • Public Key Encryption2:52

    Enable secure exchange of a symmetric session key for SSL/TLS by encrypting with the bank's public key and decrypting with the bank's private key.

  • Demo - Installing and Configuring the SSH Daemon3:10

    Install and configure the OpenSSH daemon, generate RSA key pairs, and exchange public and private keys to enable encrypted SSH connections and secure sessions.

  • Demo - Connecting via SSH1:26

    Connects to localhost via SSH, switches between root and home directories to show path format changes, and authenticates with passwords and keys to establish and close an SSL SSH session.

  • Synchronizing Directories1:13

    Synchronize local and remote files with the arcing command to transfer differences, keeping data up to date and enabling continuous live backups over a secure SSA channel.

  • Topic B: Mail Services0:21

    Explore mail services by identifying running components, common protocols, and essential terminology. Set up mail clients on Linux and understand networking and communication basics for email.

  • Electronic Mail2:11

    Learn how electronic mail works by examining smtp, pop3, and imap protocols, their ports (25, 587, 110, 143), and the mail transfer agent for outbound mail.

  • Mail Clients1:43

    Discover popular mail clients for Linux, including Thunderbird, Eudora, Evolution, and Apple Mail, plus web-based access and Outlook Web Access for Exchange servers using SSL.

  • Email Addresses0:57

    Enable management of email addresses for enterprise and personal use with aliases, using automation tools for large-scale virtual accounts and exchange server setups.

  • Unit 14 Review0:46

    Explore the ftp service, covering server setup, directory security, and authentication, including anonymous access. Understand ftp modes, required ports, and client choices for Linux to connect to an email server.
