Cron syntax about dyndns-autologin

[kopf]

The / in */25 is unnecessary. Should simply be 30 17 25 * *. Also this will be run at 17:30, not 15:30.

Feel free to submit a pull request, adding this info.

I would well be wrong - this is the first time I've looked up cron - but the information I consulted suggested "30 17 25 * *" will fire it on the 25th of every month rather than every 25th day? Once a month exactly would mean you get an email and possibly deleted.

Well, not really - cron doesn't have a way to conceive "every 25th day". All it has to work with is the current date. */25 basically means "every date of the month, as long as that date is evenly divisible by 25" - which is true for only one date, the 25th.

The purpose of this is stuff like "Every second day", e.g. */2.

Hi,

just writing here to let you know I've created a free DynDNS alternative, now that they've completely shut down their free service.
