Category:Sysadmin
These are pages for docking.org sysadmins. This is a starting point and central node for anyone who wants to install, run and manage a docking.org site locally. Sysadmin pages are *only* relevant if you have sudo on a docking.org type cluster. For other roles, see here. Once the docking lab has been set up , it must be maintained. This guide covers the events we could think of that may occur after you have a computational pharmacology lab up and running.
For security reasons, documents pertaining to authentication and access are kept in google docs

This section has two parts. In the first, Diagnosis, we enumerate the possible problems and what the symptoms might look like. In the second part, we rehearse scenarios of how to proceed. There are so many different kinds of failure that it is difficult to anticipate every one. Still, we have tried to write down the most common failure modes and sensible ways to proceed.
