TeamPages - parent, Development
Welcome
This is a comphensive index dealing with aspects of system administration and management of our clusters, as well as some of the more archine bits of setup required to make it work.
Who we are
- robinld -- systems

Index of Development Pages and Resources
Servers
- soylent-www - Primary Apache and slash server for main site.
- soylent-db -- mysql server, holds the slash database
- slashcott - Holds the slashcott site, development machine
- soylent-services - mail, wiki, other services as needed
Known Problems
- Need cron job to backup server
- There are errors in the zone file in the spf TXT record -- Mechanicjay would be happy to fix this and clean up the zone file in general, but needs linode manager access from NCommander.
- No init script for Apache.
- Broken https configuration
- Nginx running
Work Notes
DNS is completely run and managed by Linode's DNS Manager service. This was an expedient decision when trying to get off bluehost. We may want to investigate putting the master zone file soylent-services with bind and having external services handle serving out our dns.
Resources
- GroupPermissions - understanding our LDAP groups, what machines they can access, and where you can sudo
- DnsRecords - copy of the zone file pasted from the machine that was accidentally turn off
- Emergency Technical Procedures - in case of fire, break glass (Read before messing with servers)
