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
- Mostly fixed, Slash is the problem child now

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 on helium or boron and having external services handle serving out our dns.
