I am trying winpkfilter WWWcensor sample… to Block that Web Page as soon keyword encountered.
I am able to modify the content of keyword in the page i.e S*X —-> some XXX
It is reflecting in the page, all the blocked words are replaced with given keywords.What I wanted to try now is give Blocked message Page to the Browser .
To do this..,
I need to construct a custom packet with source and destination from original packet and send that packet to upper stack i.e MSTCP
and send a TCP RESET to the site ( get the ip from original packet)
— OR —- Block subsequent packets from same site.Please Help…..[/b]
You can modify the packet directly without making a copy. However, don’t forget to recalculate checksums before reinjecting the modified packet. Also, if you change TCP data length you have to change TCP header SEQ value.
