I want to ward off the pesky neighbors leeching from our cafe's free wifi connection. RADIUS and a captive portal is an overkill to setup and maintain for such a trivial task, and I also have to print vouchers. I was thinking more in the line of automatically changing the password daily using cron. But I need the password to be random and to be uploaded to another server, from where the pass can be made available to the customers (plain text format). I'm really new when it comes to scripting, so I will need the help of the pros in the forum. I can figure out that I should use nvram get wl_wpa_psk and nvram set wl_wpa_psk=password, which should be put as daily entries in "/tmp/var/spool/cron/crontabs/root", since cru doesn't save after reboot. But how can I generate a random number to enter in the crontab, and then transfer the new pass to another PC?
