Use an rcon app. Idk you guys seem fishy there has been alot of skiddies lately abusing the leet api and revealing the rcon password and then utilizing that... KillerXtream?
I will search around for a plugin. The reason I ask is because I am setting up multiple servers on my dedicated machine and I want to be able to "buy" currency for a secondary server with cash on my main server. I was just thinking maybe rcon would work to do that somehow. I will only allow rcon connections inside the network; my firewall will block external connections.
