I have 4 domains hosted on my digitalocean box and they all seem to be “auto-renewing” without my intervention.
Can you help me understand why, please?
Could it be:
- that these domain registars facilitate auto-renewal in some way
- that my server has a cron task running
- that visitor traffic does a “keep alive” for the https ssl cert (theory is that if no traffic then the ssl expires - but that’s not good to rely on, of course)
These sites all have different domain registrars that point to my server.
I checked my cron tasks and nothing stands out ( using https://unix.stackexchange.com/questions/7053/how-can-get-a-list-of-all-scheduled-cron-jobs-on-my-machine )
# cat /etc/crontab # /etc/crontab: system-wide crontab # Unlike any other crontab you don't have to run the `crontab' # command to install the new version when you edit this file # and files in /etc/cron.d. These files also have username fields, # that none of the other crontabs do. SHELL=/bin/sh PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin # m h dom mon dow user command 17 * * * * root cd / && run-parts --report /etc/cron.hourly 25 6 * * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily ) 47 6 * * 7 root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly ) 52 6 1 * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly ) # # ls /var/spool/cron/ atjobs atspool crontabs #
Occasionally I have run cert-bot on that server for adding new sites. I tend to be very specific about what I renew, as I know there is a “budget” limit on how many certs can be run in any one week. So I’m doubtful it’s that.
