Alternate Dedicated Server Tools?

[IIISystemXIII]

I just had a question about dedicated servers. I am currently Renting one from Gameservers.com And I really don't like there web based console. I log in and then it logs me right out within seconds of being on the console. Sometimes it won't kick me out for a few minutes. Non the less I was wondering if there were any kind of alternate tools or ways to be able to access my console from outside the game instead of inside it. Reason why I ask is because I try to use the console on the server in game and i can't kick people or spawn entities or anything of that nature. All I get is Unknown command every time. Not sure if I am doing something wrong on that part and If so does anyone have any insight as to how i can make it work considering I am Admin of my server that I'm renting from. But back to the alternate route. If there are any tools out there anyone knows of please let me know. Thanks in advance for those who respond.
