"I think we're gonna need a bigger web server." OpenBSD has a solid reputation for security and stability. It's well known for the OpenSMTPd mail server, the LibreSSL cryptography library, and the PF packet filter. But nobody ever talks about the load balancer, or the web server. Until now. The httpd web server provides a fast, stable, secure environment for your web applications. The relayd load balancer lets you distribute Internet application load across multiple hosts. Between the two, you can slash hundreds of thousands of dollars off the cost of building, deploying, and managing applications. With Httpd and Relayd Mastery you'll learn how to: -set up web sites -configure software to run in a chroot -run dozens or hundreds of sites on one host -dynamically reconfigure sites with Lua patterns -manage site logs -maintain free, globally-valid SSL certificates -improve performance with SSL stapling -install and maintain two-server clusters -distribute traffic between any number of hosts -stop worrying about old SSL versions and bad crypto algorithms Slash the amount of time you spend futzing with web servers.

Sudo: You're Doing It WrongUnix-like operating systems use a rudimentary access control system: the root account can do anything, while other users are peasants with only minimal access. This worked fine in UNIX's youth, but now that sysadmin responsibilities are spread among many people and applications, many people need a tiny slice of root's power.Sudo lets you divide root's monolithic power between the people who need it with accountability and auditability.Sudo Mastery will teach you to: design a secure sudo policy simplify policies with lists and aliases manage shell environments verify system integrity via intrusion detection deploy a single sudo policy across your enterprise manage sudo policies via LDAP log and debug sudo record and replay full sudo sessions use authentication systems other than passwords Master sudo with Sudo Mastery
