Verifying VPS

The best you can do is to use http://verify.cpanel.net - if that doesn't help then you'll need to contact either cPanel or your cPanel license provider directly.

 

No idea as I don't have a VPS to hand, but AFAIK, that's all there is to check licenses with cPanel directly.

 

I am not sure if this is always the case, but from my experience VPS servers do not have an eth0 interface. Instead the ethernet interface is called venet0. To check to see if your server is a VPS or regular server at the shell type:

ifconfig eth0

If you get a response like eth0: error fetching interface information: Device not found, then the server is likely a VPS.

You can type:

ifconfig venet0

and if it comes up with IP information, then the server is likely a VPS. You probably need to be root to try these commands.

Again, I'm not sure if this would hold true for all cases, but just in my experience this seems to be the case.

 

True, but cPanel does work on other virtual server environments, not just Virtuozzo. I'm not sure what, e.g., UML call their network devices.

 

All of the VPSes I have dealt with are running Virtuozzo. I guess that's where the venet0 interface name comes from. I wasn't sure if that was just a part of the VPS foundation or if it was tied to the Virtual Server setup you had. Guess that explains that little tidbit.
