Cron

Getting cron services available to users is a work in progress. Presently, cron is being architected with a central server that calls a Remctl script on shellservers which takes care of running the user's cron program.

Daemon

• Figures out which jobs need to be run
• Gets a new keytab for username/cron
• Sends the job id as well as keytab to a remctl script via command-line arguments

Client-side portion

• Figure out which user we are trying to be and which job we are running
• Change to that user's home dir and UID/GID
• Create a tempfile with the keytab we were given and get kerberos stuff for it
• Run the user's job
• If the user's job takes more than the time before it would get run again, kill it
• Send the output to the user
