I have access to a remote server, to which I login via ssh. I don't have admin rights, but I like to find out as much as possible about the machine, among other things to see If I get what I pay for. So far I tried:
top(to get the size of the memory)
uname -a(find out more about the installed kernel,...)
cat /proc/cpuinfo(get information about the CPUs)
df -h(to find out the capacity of the harddisk)
I'm not sure If the ways I've choosen are the best. I also don't know, how this information can be manipulated by the provider or accidentally contain incorrect information. At least for the CPU's I found out, that there are still 1GHz instead of 2GHz CPU'ss on that machine (I pay for 2GHz).
Are there other ways I can use to find out information about the system, even with limited rights? (e.g. if my sever is a virtual server?). Are there benchmark tools, that don't need admin-rights to be installed?
