Restrict number of clients connecting from a single IP
« on: April 19, 2009, 02:17:37 am »
Basically I'm wondering if it's possible to restrict the number of clients that can connect from a single ip address. So if I had an option of say maxClientsPerIP and then set it to 4 then only a maximum of 4 clients from a single IP could connect. If a 5th client tried to connect then they'd just fail to connect.

Thanks for any help anyone can provide.

there isn't any code that allows this currently, i've done this in the past with iptables' iplimit module though.

Thanks for the reply. I don't have access to the firewall/iptables on the server though. Do you have any idea how else I could achieve this? Only reason I want to know is that someone keeps spamming my server full of 'false' players. They just sit in spec and time out after a while. Would it be very difficult to add an option to the QVM that could limit the number of players connecting through the same IP?

Yep, it's starting to get annoying.

Subnet ban.

Won't work as I think at least 2 people are involved and the subnet keeps changing with the IP.

iptables and mod connlimit are the only real option.
Adding a limit in the QVM would probably be doable, but AFAIK its not been done yet.

Hmmm.. alright thanks for that. I'll have a look at the code and see if I can hack something up.
