dmidecode --type 17

For CentOS/RHEL/Oracle/Alma/Rocky Linux:

yum install dmidecode

dmidecode --type 17

For SUSE/OpenSUSE:

zypper install dmidecode

dmidecode --type 17

Checking CPU Specifications (dmidecode Method)

Open the Terminal and type the following commands as Root for any installed OS:

For Debian or Ubuntu:

(If not already installed): apt install dmidecode

dmidecode -t processor

For Fedora Linux:

(If not already installed): dnf install dmidecode

dmidecode -t processor

For CentOS/RHEL/Oracle/Alma/Rocky Linux:

(If not already installed): yum install dmidecode

dmidecode -t processor

For SUSE/OpenSUSE:

Check Network interfaces: ip a

Install Speedtest: apt-get install speedtest-cli

Test Network speed/ping: speedtest OR speedtest -simple

For Fedora Linux:

Check Network interfaces: ip a

Install Speedtest: dnf install speedtest-cli

Test Network speed/ping: speedtest OR speedtest -simple

For CentOS/RHEL/Oracle/Alma/Rocky Linux:

Check Network interfaces: ip a

Install Speedtest: yum install speedtest-cli

Test Network speed/ping: speedtest OR speedtest -simple
