Oh yes, I know that I can use the url in the cron job field but I used this script to test if the cron jobs works well.
You say that wget is not installed but I see it in the jail path:
awk clear dircolors du ftp head id less mawk nano nice php pico scp ssh tail vi vim.nox wc whoami
basename cut dirname find groups host ldd lesspipe md5sum netkit-ftp perl php5 rsync sort tac tr vim watch wget
Have you an idea to test the cron job functionality indipendently from my url ?
