Well, then I would suggest that you probably should look for a more reliable means of mining coin. I'm sure it is possible to find a VPS provider that allows miners to be run on their service. It seems unfortunate that you are acquiring VPS for free, yet you are still interested in breaking the terms of services and rules in an attempt to abuse and take advantage of them for Bitcoin mining. If they have gone out of their way to restrict/suspend such activity, then I would imagine it isn't something you're going to have a fun time trying to workaround. Plus, even if you do manage to make it work it will not be a long term solution. They will find out and you will be right back to square one. You can not make a living out of stealing from others.
