As we know recently CentOS 7 is released ,studded with many new features. On the part of exploring the CentOS 7, I encountered with first change. In my last post on finding the CentOS release version on CentOS 7, I gave a brief info that networking related changes is also found.
A few days back I minimal installed CentOS 7 (x86_64) on my local system. On and Before CentOS 6.x releases,I was habitual to use the command called
ifconfig . The
ifconfing command helps to provide information about the ethernet devices on your system.
On CentOS 6.x and before, ifconfig command by default used to shipped. Whereas in minimal installed CentOS 7 , I have not found ifconfig command.
This will give you the error , ifconfig command not found.
To get the ifconfig command into our system , run the below given command
yum install net-tools
Now check the ifconfig command and its path in system (
whereis command will help)
ifconfig ifconfig -a which ifconfig whereis ifconfig
How I got to know net-tools package need to be installed
Using yum command with
whatprovides options help to give you list of package which is required for that particular command.
As per man page of yum :
provides or whatprovides
Is used to find out which package provides some feature or file. Just use a specific name or a file-glob-syntax wildcards to list the packages available or installed that provide that feature or file.
We have used the below given command to find which package provides the ifconfig command.
yum provides ifconfig
