Bert Van Vreckem - Basic troubleshooting of network services
In this entry-level talk, a method for systematically troubleshooting network services (e.g. httpd, named, etc.) on EL7 is introduced.
The TCP/IP protocol stack forms the scaffolding, each layer from bottom to top being a consecutive phase in the process. At each level, the most important items to check are discussed, along with the most suitable commands for EL7.
