It is: connect timeout -> set to 60 sec
       dns resolve timeout -> set to 120 sec
	  
There is no transfer timeout, but I did found
CURLOPT_TIMEOUT (integer) - The maximum number of
seconds to allow cURL functions to execute.
So I decided to use it this time because I've never
used it before.
I've set it to 300 sec (5min).

So no matter where it "hitch" now - Curl will be
overruled by that 5 min rule.

Of course not!
Don't be ridiculous, I would never be..., obnoxious.

I did wroten another PHP script which is paresed each
10 min(cron) and is checking the first one, does it
"hangs".
From then..., no more problems!

I added another CURL option from above:
CURLOPT_TIMEOUT (integer) - The maximum number of
seconds to allow cURL functions to execute

Anyway..., last question which is bash shell related.
Second script that each 10 mins check first one, is
killing first one by it's PID(if hangs more than 30
min) and the restarting it with command:

php -f chk_tor.php > /dev/null 2>&1 &

Now, I like PHP coder am not too skilled with FreeBSD
6.2' bash shell, so here is how would I like that
command to be altered.

I want output that currently goes in /dev/null, be
saved in a variable ($OUTPUT), and then piped to mail
function where body=$OUTPUT (I will set 'subject' and
'to' by mayself).
Effect should be the same one when you instal crontab
with set MAILTO=...
I don't know bash shell syntax to do it..., thanks in advance.
