Introduction
System administration at Free Geek is primarily concerned with maintaining servers and network infrastructure to support Free Geek's day to day operations. This includes services for various stations like memtest and diskwipe.
Troubleshooting and repair
Something is broke and it needs to be fixed. Your first stop will be the tracker, look for an issue already open describing this problem, there may be a work around or somebody else may already be working on it. If there is not an issue open create one describing the problem.
Debugging resources:
- Network Layout
- Network Diagram
- Hosts list - for which service is running where
The goal during troubleshooting is to correct malfunctioning systems. Once services are returned to normal review the issue and decide if something needs to be developed to fix the issue permanently or a maintenance procedure needs to be implemented.
