How to block IP address in a guestbook?

[pcchong]

I use a free database-driven ASP guestbook. I want to add a IP address
blocking filter to it( just to block one particular guest). What is the
easiest way to do so? Thanks.

Are you sure the offender has an ip that should be blocked by this
statement? How are you verifying this?

Are you sure Request.ServerV ariables("REMOT E_ADDR") contains that ip
address? How are you verifying this?

I place this in the beginning of the first asp:

<%
dim sIP
sIP = Request.ServerV ariables("REMOT E_ADDR")
if Instr(sIP, "###.###.## #") > 0 then
Response.End
end if
%>

Anything wrong? Please advise. Thanks.

can he get through? Thanks.

I can see his IP from the guestbook. I tested this filter using my IP
address and it worked, that is why I am so puzzled. I would appreciate it if
you could suggest how I can verify the IP. Many thanks again.

Perhaps you enemy is bypassing the initial (menu?) ASP and going straight to
the guestbook ASP. Move the new code from your initial (menu) ASP over to
the page where you insert the guestbook information into your database.
That way, you enemy will be able to type in a post, but it won't get written
to your database, and therefore no one will ever see it.

HTH,

why not block both pages?

Yes, you are right. Instead of just put the filter in the index(first) file,
I should put it also in the other input files. Problem solved. Many many
thanks to everyone.
