cron job to access web site's domain

[optical]

Hello

I need to call cron.php with lynx or wget from its web site's domain and not directly from localhost i.e.
NOT
/usr/bin/lynx -source /home/USERNAME/public_html/cron.php

BUT
/usr/bin/lynx -source http://www.yoursite.com/cron.php

If I try the second line in cPanel's cron manager, I get (by email):
Looking up www.yoursite.com
Unable to locate remote host www.yoursite.com.
Alert!: Unable to connect to remote host.
lynx: Can't access startfile http://www.yoursite.com/cron.php

while if I use the first line the job seems to run correctly

I have set up my account yesterday but the domain name is registered and active (I can open it from my browser).

Thank you for your help.

cron will require the file path to work correctly.
domain will not work.

Drupal's cron.php needs to be accessed from the website's domain to work correctly. Now I've found I can use wget for this task.
The strange thing is that, even if I've set-up cPanel's cron manager to run the command every 5 minutes (just to try), the command seems to run at random: one time after 5 minutes, another time after 10 or 15 minuts, then again after 5 minutes from last run; it seems as if it is missing some "stops" along the way.
I have taken a look at the error logs in cpanel and I have seen this in the SUEXEC error_log:
"info: (target/actual) uid: (username/username) gid: (username/username) cmd: cron.php"
sometimes the same line ends with index.php instead of cron.php (this is when I manually refresh index.php).
What does it mean?
BTW what are all those strings in the main error log? just to give you an idea:

Try using PHP's cURL library to access the the file via HTTP.

http://us2.php.net/curl

Write a simple PHP script to make cURL retrieve the file via HTTP. Use Cron to run the script locally at your required interval.
