CentOS 6.5 Defaults Question

HWDPlinux · 05-17-2015, 01:59 PM

Just fired up CentOS 6.5 on a brand new Dell laptop and when I go to /etc/sysconfig/network-scripts/ I dont see the ifcfg-eth0 etc. Are those not there because Network Manager is doing the work? I remember working with these a lot in the past. Sorry, I know this is a vague question.

Edit: Also wanted to know about this virbr0 interface, is this because I installed kvm and kvm related packages? Dont remember this being present in the past.

virbr0
virtual bridge KVM uses that

be aware that 6.5 is not supported

only 6.6 is in the 6 series

cent repos ( /etc/yum.repos.d) default to using "$releasever/$basearch/os/" in the url

where "$releasever" is your installed version
in etc/redhat-release this is defined as 6.5 ( a unsupported version )

there are no new updates for 6.5

no security updates nothing

so double check that

Code:

cat etc/redhat-release

dose indeed say 6.6 and not 6.5

if 6.5 UPGRADE ASAP

What is the contents of:
/etc/sysconfig/networking/devices

Yes, virb0 is a virtual adapter and I believe that it is created by default when kvm was installed.

/etc/sysconfig/networking/devices is empty.

My follow up question is, the laptop im working on is wifi only, is it possible to bridge wlan0 the same as you can with eth0?

What about here /etc/sysconfig/networking/profiles/default

You can bridge wlan0

That location is empty as well.
