Verify if a dedicated server is really dedicated
You have doubts about your current hosting? You want to make sure your really have a dedicated server? Here's some quick tips you can check and command your can run to verify what you are really leasing.
Does the command
This tool is used to check performances on Virtual Machines
Check the network interfaces.
Run the command
ifconfig. If you see something like this:
venet0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:127.0.0.1 P-t-P:127.0.0.1 Bcast:0.0.0.0 Mask:255.255.255.255 UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1500 Metric:1 RX packets:99999 errors:0 dropped:0 overruns:0 frame:0 TX packets:99999 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:126223307 (120.3 MiB) TX bytes:2897538 (2.7 MiB) venet0:0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:6x.xxx.xxx.xxx P-t-P:6x.xxx.xxx.xxx Bcast:6x.xxx.xxx.xxx Mask:255.255.255.255 UP BROADCAST POINTOPOINT RUNNING NOARP MTU:1400 Metric:1
you are probably have a VPS since venet0 is telling that this server is being an OpenVZ VPS. Note: This is not 100% foolproof, some VPS like Xen have an eth0.
dmesg as root. If you see something like:
VMWare SVGA device acd0: CDROM <VMware Virtual IDE CDROM Drive/00000001> at ata0-master UDMA33 da0: <VMware Virtual disk 1.0> Fixed Direct Access SCSI-2 device
Then you are using a VPS.
Check if some files exists:
If it's a VPS running OpenVZ they'd have a file called
/proc/user_beancounters. View http://wiki.openvz.org/Proc/user_beancounters for more details.
/proc/vz/veinfo exists (for OpenVZ) or
/proc/xen (for Xen)
/proc/self/status has an
If one of these file exists, then you have a VPS.
You could do a reverse IP lookup to check to see if any other websites are hosted on the same IP.
lspci and look for RAM memory:
Qumranet, Inc. Virtio memory balloon. Then you have a VPS.
Check The Computer Info:
By checking the computer information, you can find very quickly if you have a virtual processor or not.
grep 'model name' /proc/cpuinfo
If you have a virtual hosting, you might see something like:
model name : QEMU Virtual CPU version 0.15.0
Check The Computer Manufacturer:
By checking the computer manufacturer, you will now what kind of manufacturer you have.
dmidecode -t system | grep Manufac
