someone recommended that i should give br0 the same hardware address as eno2. I did that, and restarted the vm, and it still does not work. Here is my current host interface config: ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft

I should have what i want to achive. The server is intended as a host for VMs. Our network has multiple VLANs, and the VMs will be connected to different VLANS. The interface eno1 is for host traffic and eno2 is connected to the trunk port of the switch, making the different VLANS availabel to the VMs via the br0. I want to use a VLAN-aware br0, so that I specify in my VM config (on the host

Hi I am having a weird problem which I cant figure out - so I was hoping someone here could give me a hand. First off the end goal is that a specific server in my network runs an IPSEC connection to another company and I want all other servers to route traffic for the IP on that network through this single server. Server 1 in this example is the server that runs the IPSEC connection. (CentOS

Hi, Can you show as the config of eno4? And can you diff the config of eno1 and eno4. Looks like there is a difference somewhere. Regards, Simon > > > This server is equipped with four nics

Okay, so I''m trying to setup my multiple ISP setup that I described earlier. I have: # ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: em1: <BROADCAST,MULTICAST,UP,LOWER_UP>

I think this is a bug: CentOS 5.4 using Samba 3.4.7. If the server IP address changes, nmbd complains every few minutes that "There is already a domain master browser" on the old IP address. Although "Chapter 41. Managing TDB Files" states: wins.dat N WINS database iused only when wins support = yes has been set. This gets rebuilt or updated at every restart. that does

Hi, I would like to run a network firewall as a VM on a KVM host. There are ~ 25 VLANs delivered to the KVM host on three dedicated links, no LACP or other things. I have the VLANs 100-180 on the host's enp1s0, the VLANs 200-280 on the host's enp2s0 and the VLANs 300-380 on the host's enp3s0. To save myself from configuring all VLANs on the KVM host, I'd like to hand the entire

So i was playing around with Samba multi channel and it was not working as i originally expected it. I have two hosts: my workstation running up to date Windows 10 with 2 interfaces my server running Gentoo with Samba 4.5.4 with 2 interfaces (all connected to the same network) workstation has IPs 192.168.2.114, 192.168.2.115 server has 192.168.2.16(enp2s0f0),192.168.2.17(enp2s0f1) i'm

I''ve just installed Xen on a new CentOS 5.1 system, and I can''t seem to make xenbr0 connect to the network. This system has a single physical network card. Apart from creating a few DomU guests, I have not changed any of the configuration. After running network-bridge, xenbr0 and friends are created, but the address and routing info is not moved.

Hello, I am trying to boot a VM in libvirt that has 2 interfaces. The first interface is connected to the default network and the second connects to a bridge interface on the host. When the VM boots the first interface doesn't receive an IP address from DHCP. It works when the VM only has one interface though. If I login to the VM using virsh console I noticed that in NetworkManager the

Dear CentOS-Community, we are facing the following issue: A secondary ip address seems to be automatically added to a nic which causes several issues in our setup. This server is equipped with four nics which are currently in use: # nmcli con show NAME????? UUID????????????????????????????????? TYPE????? DEVICE eno2????? cb6fcb54-be52-4ab6-8324-88091a0ea1a0? ethernet? eno2 eno4?????
