Information about your server's operating system is available in the Welcome mail you received when you purchased your server at Heberdomaine.

If you want to know about the Linux operating system installed on your server (distribution, version, architecture), follow the instructions below:

  1. Log in to your server as root via SSH.
  2. To find out which distribution and version of the operating system are installed on your server, use one of the following commands:

cat /etc/issue             

cat /etc/redhat-release    

cat /etc/debian_version    

      3. To find out what architecture your operating system uses, use the command:

      If the result of the command "uname -m" contains _64: Your operating system uses 64-bit architecture

uname -m                      

getconf WORD_BIT             


Here are a few examples:

A - Distribution: CentOS, Version: 6.2, Architecture: 64-bit
