MCDzienny

Many of the zombie survival servers based on MCDzienny are having problems due to the fact that players can press Enter to save a spot and then tease a zombie into believing that they're gonna get him/her until the player presses "r" to re-spawn.
This was blocked in Minemaniacs zombie server, and it shows that they spawn back to the spot but automaticaly brought back to where they were. I hope this can be done, then I would be able to set-up a zombie server without cheaters.

I don't know if there's already a option in MCDzienny, but if you want to code it yourself...
Maybe a OnPlayerMove EventHandler and if he moves more than x blocks and is not operator / admin, setback?

That's how the owner of minemaniacs explained how it was done, but I'm not good enough to code that...

+1 It's a good suggestion, maybe dzienny will be able to add such an option to the zombie game mode.

In the zombie settings, set DisallowHacks to true, and change your speed hack detection threshold to 50 or something.

Yup i believe this already exists, fairly simply to code yet:
Check players position in a regular cycle, if it differs too much in x,y,z reset them to where they are. Lag can be a problem here.

Also be carefull with the y(height in minecraft) as falling with small lag can get people stuck in the air (i have been there )

It exists and it works well. Ismellike described how to set it up (it should be turned on by default).

The speed hack prevention checks a movement distance each time a player reports a position change, which is every 40ms or so, and server lag shouldn't affect it. A player's slow computer may - if he or she gets below 25fps - but it's rather a rare case. MCDzienny doesn't do a check for speed falling, because it may give false positives (if not fine-tuned) and its abuse is unlikely anyway. MCDzienny does check for speed climbing and horizontal movement of course.

I've also noticed that it doesn't check the speed in water, that can be exploited... maybe

It does a check, but it treats water and lava same as air. I would have to add additional rules for the checks that would take into account whether a player is in some liquid. It's possible, but I'm not going to do it, at least now. And anyway, a trained staff is the best mean to catch and reform abusers
