New to Cent OS7 - Network Issue
New to Cent OS7 - Network Issue
Hi I'm new to Centos 7. I just installed on Desktop. I'm not able to ping other machine or internet.
What need to be checked. Following is the output of ifconfig -a

Re: New to Cent OS7 - Network Issue
What is the output from ip route show and what happens if you ping 8.8.8.8 ?
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.

Re: New to Cent OS7 - Network Issue
Is this a physical machine or a VM? If it's a physical machine what is the output from lspci -nn | grep -i net ? If it's a VM does it work if you tell it to use DHCP to get an ip address?

Re: New to Cent OS7 - Network Issue
It is a physical machine. I did not get any output
Re: New to Cent OS7 - Network Issue
My command was mangled. Try it now that I've fixed it. Check if lspci is even installed first and install pciutils if not.
