Allow Only 1 Session Per Account

I tested the code submitted above and it actually works perfectly as intended as far as I can tell. I was able to log on a single character from any account with any status, but if I tried to log on a second character from an account below the set exempt status, it would get disconnected after hitting "enter world". I also verified that the exempt status still works and you can log in as many as you want still if your account status is higher than the exempt setting.

So, all that is left is to figure out how to make it kick the character in game instead of disconnecting the new one trying to log in. I am thinking maybe the way to do it could be found in the code that keeps people from logging in the same character more than once. Since if you try to log in a character that is already online, it will boot the online character and let you log him/her in again with the new connection. This is mostly important for cases where a character may be bugged and stuck logged on. It would be extremely important on Windows servers using this feature, due to player ghosting.

I'm going to get this one PEQ tonight, and see how it goes. Since we're Linux we don't suffer from player ghosting, and LDs usually disconnect in under a minute so it's no problem for us as written.

Been running it on my server a couple of days and haven't heard any issues with it yet. Seems to work exactly as intended. I am still trying to figure out where in the code it is checked if you are logging in the same character, because that is the only time it will boot the character that is online. If I can find that, I think we can add that to this code and have it kick the character in game.

Another nice bonus to this code is that on Windows servers running IP Limiting, character ghosting can cause players to be locked out of the server. But, with this rule in place, once we get it set to kick the in game character, it will resolve that issue and let them log in again.

If you change the iterator from:

Code:

LinkedListIterator<ClientListEntry*> iterator(clientlist);

to

Code:

LinkedListIterator<ClientListEntry*> iterator(clientlist, BACKWARD);

it might allow the new login and kick off the older ones. I've not tested this with the code above, but I have tested a backward iterator, and Reset() starts it at the end, and Advance() moves it towards the start.

Thanks, Derision

I will give that a try along with a few other things I have been wanting to test as soon as I get my new test server up and running. Going to run VMWare on my Windows PC to have another Linux installation without having to dual boot or build a 3rd PC. It should be MUCH easier (on me and my players) to do code testing once I get Linux running on VMWare.

This exploit is majorly serious... Players can in fact duplicate tradeable items with this.. I hope that it gets fixed soon because until then Raid Addicts will not be Unlocked... Our economy has suffered greatly due to this..

Azamorra was a great coder who donated to our server an excellent fix for this , but it seems we have lost the code for it.. Aza if your out there please come back and help the community with this fix..

What are you talking about KingMort? Are you sure the issue you are referring to is related to this topic? More details would be helpful. If you are having issues with the account limiting, you can disable it in your rules.
