hello there guys, i have setup crontab as uzer.

$ whoami
uzer

$ crontab -l
50 23 * * * /usr/local/bin/checkip

$ cat /usr/local/bin/checkip
#!/bin/sh
/usr/bin/lynx --dump http://checkip.dyndns.org > /home/uzer/checkip
/usr/bin/echo `cat /home/uzer/checkip` | mail uzer@fqdn

$ ls -l /usr/local/bin/checkip
-rwxr-xr-x 1 uzer users 145 2006-01-22 12:36 /usr/local/bin/checkip


when i perform the script manually, it works. cron works for some reason on the first run only. after that, it no longer works. i get the the following e-mail for the local user and a blank one for uzer@fqdn.

Subject: cron: /usr/local/bin/checkip

To me this is the best way to find my ext ip and notify me through e-mail. I have cable modem so my connection is always up. I do it this way because i have a godaddy subscription.

ddclient will mail the ip update info to your user

yah i actually have ddclient setup to mail me twice a month and update my dyndns.org account. i just wanted to have a daily one also. is there way to configure ddclient to only send an e-mail and not update dyndns.org? if i run this daily then they might think i'm an abuser.

i'm not sure it's possible for ddclient to be abusive.
