Modem Tapping?

[Curt1zzle]

Grats -

Now about 30 forum browsers are going to log on Era and try this lovely fairly unknown trick.

[Evil_Trunks]

it's not as bad as un-named people on Era who use x y warp hack combined with speed hack

Cheaters will always be around forever you just need to learn how to deal with them, or atleast until someone really smart comes a long. That will be the day..

So, forever is just until someone smart comes along, and then time as we know it stops. I guess Kaimetsu really isn't that smart then!

[Mitch]

Exactly, but I believe Kaimetsu is very smart however, their will always be a hacker just as good as the programmer.

Jenn will probably find a way around it, I just havn't confronted her :P.
I was hopeing there was something to do with the graal client and such

I fail to see how something like this would make you download faster. You'd actually get corrupt or incomplete packets...

[Snakeandy7]

I was just going to say the same :[

[Kaimetsu]

There are all kinds of ways to deal with abuse. Perhaps Graal's speedhack tolerance should be modified to consider the actual speed of the player, rather than just the number of data packets.

How would the actual speed of the player be a better choice for the speedhack detection than the frequency of data packets?

In that it covers a wider range of exploits, including the one described in this thread. It tackles the undesirable phenomenon directly.

In hindsight, I probably should've used the word 'extended' rather than 'modified'. Checking data packet frequency is still a good thing, I'd say.

I disagree. In this case, I see the crazy movement speed as just a symptom of all those packets being sent at once. Why tackle the symptom and not the problem? Also, can you provide some examples of these other exploits?

As far as I know, the system we already have should catch these "modem tappers". I think the biggest problem is that many servers don't even use the speedhack detection system. A quick check of UN shows that it isn't used at all. Another quick check shows that Era is using it but has an unreasonably high value for the tolerance (290). A value of 90 should catch most speedhackers. Stefan's words were that simple lag would not set off the alarm with a value of 90. Still, if it happens just once, warn them. If it happens quite frequently, you've got an abuser on your hands.

Movement packets are actually UDP datagrams, right? From what I understand of the protocol, it's a very fire-and-forget system. If the client tries to send them when the connection is down, they'll just fail and be forgotten. They don't enter any kind of queue, so it's not like the server will be receiving more than usual once the connection is reestablished.

Why tackle the symptom and not the problem?

Why tackle a single cause and not the problem?

The problem here is that players can move in ways that weren't intended. That is the problem. Your advised approach is like saying we should ban cigarettes so we don't have to bother looking for a cancer cure anymore.

Also, can you provide some examples of these other exploits?

Would it not currently be possible to send arbitrary movement packets? As long as I don't send too many of them, I can move as quickly as I want. I can warp randomly around the level as long as I don't exceed x packets per second.

u can make ur items invisable with moden tapping

[Snakeandy7]

Don't forget that Era uses graal2k2's system. I thought it was normal at 290 with it being changed to GK. So I didn't bother asking x-x. But Lance, That doesn't detect modem tappers.
