java script is client side.
it only prevents that a form can be submittet.
what if you circumvent that and post directly?
as we know, simulating a post ist quite easy:
telnet to host port 80:
"POST /superposter/gna.php HTTP/1.1\r\n
Host: www.blabla.ch \r\n
User-Agent: whatever you want\r\n
Accept:
text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plai
n;q=0.8,image/png,*/*;q=0.5\r\n
Accept-Encoding: gzip,deflate\r\n
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7\r\n
Keep-Alive: 300\r\n
Connection: keep-alive\r\n
Referer: www.blabla.ch/urli/index.php
Cookie: PHPSESSID-1111111\r\n
Content-Type: application/x-www-form-urlencoded\r\n
Content-Length: 100\n
\r\n
action=login&nick=username&password=password&submit=LOGIN
\r\n"
if you get that you cannot check if he used your javascript or not ,-)
he might check your session-id, but what if the client gets a session id
and uses that one to fill in the form.
that soo easy :-) (i'm using such a tool as a proxy for an online game
since about 5 years ,-))

Hi folks
In my (recent) experience, this problem is not related with the form but directly with the database.. The spammer seems using an automatic bot that is sending content to generic database fields (so my suggestion would be changing the table field names to strange ones instead of changing field names of the form); Let me tell you what happened to me: I have a small guestbook in ASP (not self made, is a free code found online) used by me and 7 more friends for a private fanta-soccer-game website (so absolutely not a visited website). I begun to have those spam messages in it and I fgured out the following: I had since the beginnning the possibility to enable-disable the form fields 'sender email' and 'sender website' and, being only 8 ppl, I disabled them immediately during the guestbook installation: checkingthe database after the spamming I found those fields in the database FULL WITH INFO even if there was no input field in the form. Thats why I can tell tah tis problem is not form-related. Solutions (possibility that I had from this premade guestbook):
1) enable Session ID check (so the post must be submitted from the form and not from outside)
2) enable cookies (to prevent spamming the gustbook with multiple comments)
3) enable the loved/hated security images
Hopes this helps
Cheers
Filippo
P.S: another system that seems working (I'm testing it) is to put the guestbook pages on a different server from the main website (im including it in a <iframe>).. Seems that this is confusing the bots..

Works fine, but you think of the visually impaired. There are captchas
which provide the number also as sound. But I wouldn't use captchas on
business websites, it's to annoying for the users to type in the number.

Often it helps if you give the fields "unsuspicious" names. "meinfeld4"
instead of "recipient" and so on...
I use mod_security [1] with the rules from gotroot.com. mod_security
blocks the spam before the form gets processed. Additionally, it
protects the server from SQL-injection and other attacks.

Hello,
on the NANOG-List people are currently slaughting each other in matters
of RBL-Usage and -Policy.
This reminded me of a project I've been wanting to start for a long
time.
Does someone have a decent script that would extract URIs from mails
that have been classified as spam in order to feed an URIDNSBL with it?
Regards.

Would someone please remove Knowledge Computers from the list ?
During the last discussion regarding what is allowed to be posted for
sales we got an agreement.
see http://lists.swinog.ch/public/swinog/2006-May/subject.html "Rules
for used hardware selling"
Knowledge Computers is definitely no ISP nor it has in any way something
to do with Switzerland.
Actually if they would send e-mail to my account they would be tagged as
spam...
