I have a small tool without many options but it does very well his job :
Kick and ban !
Small, so easy to use and you can let it turned on for long time without crashing server
But it is expensive !
I can sell it to you for 1000 $/month with 12 months obligation ^^
No ?!!! Oh ok ! Free for you dear admin-friends !
I will send you when i will go to home tonight
But all rcon tool doesn't match same way with all different server hosting -(
Since Crysis 2, i had possibility to try several hosting like verygames, nfoservers, gamehosting, multiplaygameservers and i noticed that rcon command could more crash servers with certains hosting providers.
Today, i rent the 3 servers to only gamehosting with London location cause it accepts permanent rcon tool without making crash servers
(and also cause they are the less expansive since we have negociated ^^)
In memories, not possible with verygames and many crash too to multiplay hosting.
I remember it was very nice too with nfoservers (but servers locations too far from France so too high pings -()
For C3EAI, i use it today only for certains ways :
Change map/gamemode on a server, to know the id from a player reported for ban him using ban list in settings server or manage the reserved slots.
Thats all. Sure this tool make crashes when used for kick or ban !
Stop use it ! Just use the one i will sent to you soon -)
