Dear Niharendu,
You have a valid point. The CCL search engines (the Text and Regular
Expression ones) are coming and going out of operation lately.
There are reasons for it...
1) I (the maintainer of CCL) am going to Europe for 5 weeks starting
Jun 15. I will have occasional contact with the CCL.NET computers
over the modem and local European Internet Providers, but will not be
able to do any extensive file transfers or editing. I will not be also
able to "push the button".
2) With the current level of crackers activity and spammers looking for
exploits, I am quite worried to leave these options on. Bad guys can bring
the machines down by submitting searches every second or so, and I need to
write a lot of tricky code to prevent it. Moreover, I need to really
audit the security of these scripts. For example, the longer regexp
searches give you the option to return result via e-mail, so you do not
have to wait for the browser to show you something... Now... THERE IS
NO WAY to make sure that e-mail address entered is the legitimate one.
You can enter george<<at>>whitehouse.gov and it will take it, and
diligently
send the results there... Yes... I know... There are ways... There is
subscriber list to check against... But it is work... work... work...
3) Many exploits are possible with search engines, and I do not necessarily
want to advertise them on the list.
We will see what I can do before I leave, but the likely scenario is that
I will disable these services for a while, until I am with "physical
contact"
(oh well... could not help it... this is a kind of contact left at my age...)
with computers, so I can fix stuff within hours...
In any case... It is the warning that if something goes really bad when I am
out, the CCL will need to wait till end of July before it is alive again.
