omg dude, u need to learn BASICS of computer.
-Packettheres lots of packet editors. my favorite is CommView 6.x versions.
you wont be able to get into locked servers dude, you need to modify game or find a way to send packets from certain source ports.
to be able to send packets from known source port with commview .. you will have to edit each packet, becaue checksums will change if u change port...it takes LOOONG. well maybe theres easier way, i havent looked into it, but in theory it works and also works on bots..so it is possible.
when they locked server my bot successfully entered, but i couldnt. for example if i go into game and record the packets where i run over ammo box (as demonstrated
-HERE-) and resend them, then ill get ammo. thts because the source port is still same. it wont work exactly like this on locked servers, because game still recieves disconnect packet and u wont be able to continue. u need to modify game or block that disconnect packet...
im not 100% sure what is that disconnect packet, maybe theres more than one, but i know for sure that bot got into locked server and thts all the proof i need to be sure its possible.
