The use of "cron jobs", which are processes that are run automatically at certain times, in accordance with a "crontab" file set up by each user, are allowed on IperWeb servers, subject to the following conditions and restrictions:

• The user's account must be Advanced or Webmaster.
• The job must not execute more often than every two hours.
• The job must generate no greater impact than a CGI script. See the guidelines on resource usage.
• The job must be "niced". For details, read the man pages about the nice command (man nice). The preferred value is 10 or greater.

Other Information

This policy exists to protect the servers from abuse. However, it does still allow reasonable usage of cron, which is forbidden by most providers.
