similar to: default gw route has gone?

Hi, I have installed CentOS 6.2 x86_64 and KVM/Qemu and I have some troubles with network. The first case: ----------------- The configuration is: - CentOS 6.2 (hardware machine) has one Ethernet interface with static IP address (eth0). - Virtual machine has bridge network interface with eth0 interface on CentOS 6.2. This bridge is created using wizard integrated with virt-manager. - Bridge

To route a subnet in ipv6 there are two possibilities: - add route commands for the subnet in each computer - or use neighbor proxy in the router server I prefer neighbor proxy. So I have to activate neighbor proxy in the router: sysctl -w net.ipv6.conf.all.proxy_ndp=1 and I have to add entries for each client in the subnet like ip -6 neigh add proxy

Dear Simon, every second IP-address is unwanted. We restarted? eno4: nmcli con down eno4; nmcli con up eno4 and the second address vanishes. Then after a few ours, the second ip address reappears. This is the config-file of eno2: # cat ifcfg-eno2 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes

I am installing a new Samba 4.2 Active Directory server on CentOS 7. I followed the Wiki instructions on how to create the server. I am using sernet-samba 4.2 binaries. Everything seems to be OK on the Linux side but I cannot get any windows client to successfully join the domain. Each attempt returns the following error message "RPC Server in not available". Below are the config file

Hi, I was recently going through the how to located here: http://wiki.centos.org/HowTos/Laptops/WpaSupplicant This how-to shows the steps to follow to get a wifi interface working without using NetworkManager and subsequently how to have wireless working withouth having a user login. Anyways, when going through this I was having issues because everything seemed to work but I was never

Hi All :) I have three servers, all with centos 7 installed 3 days ago. I need on them "old" naming scheme (ethX) for network interfaces, because of that: # grep GRUB_CMDLINE_LINUX /etc/sysconfig/grub GRUB_CMDLINE_LINUX="rd.lvm.lv=centos_node-XY/swap rd.lvm.lv=centos_node-XY/root rhgb quiet ipv6.disable=1 net.ifnames=0" net.ifnames=0 was added and afterwards I ran:

I have been trying all sorts of things to get this working. nfsv4 works fine if I just use the nfs-v3 form of export i.e. /nfs4exports 192.168.230.237/24(ro,fsid=0,sync,insecure,no_root_squash,no_subtree_check,squash_uids=0-99) /nfs4exports/NDG 192.168.230.237/24(rw,insecure,no_subtree_check,nohide,sync,no_root_squash,squash_uids=0-99) but this is inherently open to all on this machine. so then

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?????

Hi all. I have currently an OpenVZ server: uname -a Linux vader8.superhost.pl 2.6.32-042stab055.16 #1 SMP Fri Jun 8 19:22:28 MSD 2012 x86_64 x86_64 x86_64 GNU/Linux cat /etc/redhat-release CentOS release 6.2 (Final) lspci | grep -i eth 01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03) cd /etc/sysconfig/network-scripts

On my CentOS 6 partition of my laptop: First note that for this test, NetworkManager is not running because I did: chkconfig --del NetworkManager and then rebooted. Here is my ifcfg-eth0: DEVICE="eth0" NM_CONTROLLED="no" ONBOOT=no HWADDR=xx:xx:xx:xx:xx:xx TYPE=Ethernet BOOTPROTO=none IPADDR=192.168.2.5 PREFIX=24 GATEWAY=192.168.2.1 DNS1=192.168.2.1 DNS2=192.168.2.1

What about eno2, you also have two IP addresses there and even in the same subnet, is this wanted or not? Can the second address of eno2 be found in the ifcfg file? Both eno2 and eno4 have "scope global secondary dynamic"

Hi! I just upgraded a machine to 7.7.1908 and the default route is not being set on boot. This particular server has a bonded interface, and the corresponding configuration for the master is ( /etc/sysconfig/network-scripts/ifcfg-bond0): TYPE=Bond BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=yes NAME=bond0 DEVICE=bond0 ONBOOT=yes IPADDR=10.3.20.131 PREFIX=24

Then after a few ours, the second ip > address reappears. That's really interesting. Doesn't NetworkManager also store other settings in a different location, not the ifcfg files? I think it does so and
