How does VBulletin get the system information without the use of exec? Is there any other information I can get about the server without exec? I am interested in:

  • bandwidth used
  • system type
  • CPU speed/usage/count
  • RAM usage

Use PHPSysInfo library

phpSysInfo is a open source PHP script that displays information about the host being accessed. It will displays things like:

  • Uptime
  • CPU
  • Memory
  • SCSI, IDE, PCI
  • Ethernet
  • Floppy
  • Video Information

It directly parsed parses /proc and does not use exec.


Another way is to use Linfo. It is a very fast cross-platform php script that describes the host server in extreme detail, giving information such as ram usage, disk space, raid arrays, hardware, network cards, kernel, os, samba/cups/truecrypt status, temps, disks, and much more.
