  1. OpenSSL Cookbook 2023-05-31

    The definitive guide to using the OpenSSL command line for configuration and testing.

    Topics covered in this book include:

    • key and certificate management,
    • server configuration,
    • a step by step guide to creating a private CA,
    • testing of online services.
  2. The Maintainers 2019-04-16

    The Maintainers is a global, interdisciplinary research network that takes a different approach, one whose conceptual starting point was a playful proposal for a counter-volume to Isaacson’s that could be titled The Maintainers: How a Group of Bureaucrats, Standards Engineers, and Introverts Made Technologies That Kind of Work Most of the Time. Network members come from a variety of fields, including academic historians and social scientists, as well as artists, activists, engineers, and business leaders. All share an interest in the concepts of maintenance, infrastructure, repair, and the myriad forms of labor and expertise that sustain our human-built world.

  3. A PCAP-based tool that allows you to specify an extended regular or hexadecimal expression to match against data payloads of packets. It understands many kinds of protocols, including IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw, across a wide variety of interface types, and understands BPF filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.

  5. Pro: no need to setup a DNS server to test virtualhosts Con: keep in mind that all "fake" hosts will point to 127.0.0.1!

    1. Use /etc/hosts to declare test hosts / domains / subdomains
    #<ip-address>	<hostname.domain.org>	<hostname>
    127.0.0.1	localhost.localdomain	localhost
    127.0.0.1	host.localdomain	host
    127.0.0.1	sub.host.localdomain	sub.host
    ::1		localhost.localdomain	localhost
    
    1. Allow per-user virtualhost definition in either (depending on your distro)
    • /etc/httpd/conf/httpd.conf
    • /etc/apache2/apache2.conf

    Include /home/albert/.httpd/*.conf

    1. Profit! Create virtualhosts with local hostnames :)
  6. Twisted 2015-04-24

    Twisted implements a variety of networking and communication protocols and exposes them all as method-calls on your Python objects. Client and server implementations are provided for various standard protocols, including:

    • HTTP (twisted.web)
    • IMAP, POP, SMTP (twisted.mail)
    • DNS (twisted.names)
    • TLS (core)
    • SSH, Telnet (twisted.conch)
    • IRC, XMPP, OSCAR (twisted.words)
    • Ethernet, IP, TUN/TAP (twisted.pair)
    • NMEA (twisted.positioning)
