Wireless inteface configure as bridge

0 votes
523 views

I m using centos 7 in laptop and kvm as virtualization to run windows guest VM. Currently I m using NAT as default setting for guest VM, my internet is fine but can't resolve some domains and sites.

So want to come on bridge.

As per my understanding bridge can not work while device is managed by NetworkManager.

Is there any utility or tool to use to scan wireless device in network and connect them as I want to stop to use Networkmanager to use laptop wireless interface as bridge for my guest VM.

How did you come to this conclusion? Based on which reading?

You cannot do what you want

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Networking_Guide/ch-Configure_Network_Bridging.html

"Note that a bridge cannot be established over Wi-Fi networks operating in Ad-Hoc or Infrastructure modes. This is due to the IEEE 802.11 standard that specifies the use of 3-address frames in Wi-Fi for the efficient use of airtime."

According to the Red Hat RHEL7 Networking Guide you can't bridge wireless interfaces. IIRC there's a reason mentioned in that guide and here's another one:

However there's a debian wiki entry that says it's possible using ebtables:

NetworkManager substitute on CentOS

I'm investigating how to setup KVM so I can run VMs without having to use VirtualBox or VMware, or etc.

All the HOWTOs I see tell you to disable NM.

I use NM to manage VPN clients that I use for remote access to my office, among other places.

How would I manage those VPN clients if I didn't use NM? I haven't found any commands that appear to be suited to that purpose.

How to configure VLAN in CentOS7?

I encountered a problem when creating a VLAN interface according to the Red_Hat_Enterprise_Linux-7-Networking_Guide. I configured the parent interface ifcfg-eno1 as follows:

DEVICE=eno1
TYPE=Ethernet
BOOTPROTO=none
ONBOOT=yes

And I created a new file named ifcfg-eno1.5, the content is:

DEVICE=eno1.5
BOOTPROTO=none
ONBOOT=yes
IPADDR=192.168.81.3
PREFIX=24
NETWORK=192.168.81.0
VLAN=yes

Then I restarted the network:

 systemctl restart network

After that I found that I couldn't connect to the Internet, even couldn't ping the gateway. I thought it might be I didn't set the GATEWAY in ifcfg-eno1.5, so I added the GATEWAY=192.168.81.254(My local area network gateway), it didn't work.

Could anybody teach me how to create a VLAN interface in CentOS7, or tell me what' s wrong with my configuration, more detailed more better.

Running MacOSX as VM under CentOS 5.10?

Is it even remotely possible to run MacOSX (or Darwin) as VM under CentOS 5.10/ xen? Or am I better off not even trying and just getting a MacMini or MacBook to just jack into my LAN? I just need a 'build box' and possibly something to do light testing (eg does the program run? Does the GUI come up?).

I can cross-build for MS-Windows using mgwin32 and I have VMs for CentOS 6, Fedora, Ubuntu, Debian, etc. Only MacOSX is missing from the 'mix'.
