The general idea is that you can run a function directly from the command line, so you can also run it directly from system cron. The difference between that and "external cron" is that it completely bypasses web2py's internal cron handling, which the last time I looked at it (it's been a while) did not look reliable to me. Here's a sample from my crontab template (system crontab, not web2py crontab). I run web2py in a virtualenv; hence the activate. The controller/function is tasks/idf. 0 * * * * source %(virtualenv)s/bin/activate && cd %(web2pydir)s && python web2py.py -J -M -S %(appname)s/tasks/idf -a "<recycle>" >> /tmp/cron.output 2>&1 > > thanks > > On Saturday, January 25, 2014 12:55:50 AM UTC+1, Jonathan Lundell wrote: > On 24 Jan 2014, at 3:38 PM, Alex <mrau...@gmail.com> wrote: >> I've got a big issue with external cron jobs.
