I recently bought a low-end VPS from a company in the Netherlands which was running OpenVZ. The VPS had an IPv4 address and an IPv6 address and I was hoping to set up a VPN so that I could use it to connect to the IPv6 world. I was using Debian 6.0 32 bit as my OS and I installed openvpn and ran the command "openvpn --dev tun0 --mktun" and this somehow crashed their production server. They moved me to another node and I tried it again with the same result. They moved me to my OWN node and I decided to use CentOS 5.7 32 bit and ran the same command and crashed that node as well. Now they don't want me as a client and won't give me a refund.

I feel like it is their fault for having servers that crash with a simple command and I deserve a refund since I payed for a month and used it for less than a day. What do you guys think?

I think it's 'paid', not 'payed' (or rather I know) and you do deserve a refund - presumably you told them how to reproduce the problem so they have no reason to think you were doing something nefarious. I also think you should name them so that others can stay away from this provider.

I am curious about two things - did they investigate and inform you about the cause of the crash? And what, other than the OS, was the difference between 'another node' and '[your] OWN node'?

I was in the middle of setting up my VPS when I typed in the command and immediately I got an error and was unable to log in or reset my VPS. So, I knew what command was causing the problem and I told them this from the beginning. What I didn't know was that it wasn't just locking me out, it was causing the entire node to crash with cpu loads in the hundreds. The moved me to a different node and I tried the same thing with the same result (maybe that was foolish of me). They moved me to my OWN node (meaning that I was the only one on the node) and the same thing happened with a different OS. This is when they decided that it was my fault for crashing their servers. I gave them a copy of the entirety of the console I was using to log in so they could see what I was doing, and I even found a forum discussing the problem:

I think they were just so freaked out by the prospect that I could crash their servers, they would rather immediately ban me than listen to me when I said that it was their problem and I was simply the first one to run across it. The company is based in New Zealand (not the Netherlands. My mistake) so I don't know how I can get them to give me a refund. Besides, I only payed them $7. I was just looking for another opinion to see if I was to blame for this (I didn't know what I was doing, etc). They haven't contacted me since last night when it happened so I don't know if they have investigated the cause or are just blaming me.
