similar to: Centos 7 Server Forgets IPv6 Address On Reboot

Hello, in /etc/sysconfig/network-scripts/ifcfg-eth0 I have this <ifcfg-eth0> ... IPV6INIT=yes IPV6ADDR=prefix::5 IPV6ADDR_SECONDARIES="prefix::2 prefix::3 prefix::4" IPV6_AUTOCONF=no IPV6_DEFAULTGW=prefix::1 IPV6_DEFAULTDEV=eth0 </ifcfg-eth0> when I enter ifconfig the IPv6 addresses are in a different order <ifconfig> eth0 Link encap:Ethernet HWaddr ... inet addr:...

I know how to use 'ip' to set up a static route, e.g.: ip route add 192.168.128.0/17 via 40.53.24.3 dev eth0 But if you reboot or restart network, you loose this. Thus you have to make it persistant. I found: http://www.cyberciti.biz/tips/configuring-static-routes-in-debian-or-red-hat-linux-systems.html where it says to add to ifcfg-eth0: 192.168.128.0/17 via 40.53.24.3 But this

Hi, I'm wanting to configure a CentOS 6 server to have a fall-back default route via a second network interface. Given: - eth0 with 192.168.0.10 on subnet 192.168.0.0/24 gateway 192.168.0.1 - eth1 with 192.168.1.10 on subnet 192.168.1.0/24 gateway 192.168.1.1 Where eth0's network is a "back door" to the internet, and eth1's is the "front door", I believe I can

I have centos 64 6.5 I installed bridge-utils I installed tunctl I added BRIDGE=br0 to ifcfg-eth0 I created ifcfg-br0 with correct settings I did service network restart and I get an error about br0 not present. When I plug in the second network (USB to ethernet) It detects as eth1 What do I need to change to get this to work. Thanks, jerry

Ok, we can take both but needs to be in a specific order. So, we have two ethernet interfaces, A and B. And both are defined in /etc/systemd/network/ to use dhcp. How to guarantee that the crap provided by dhcp to A (dns, gateway, ntp) is the default? To use an example, /etc/resolv.conf should end up like nameserver IP.for.A.DNS nameserver IP.for.B.DNS domain A.domain.com Now, this must be done

I want to add the following route command route add -net 192.168.2.0/27 gw 192.168.2.3 via the normal network setup. The result should be the following routing table (the first line): 192.168.2.0/27 via 192.168.2.3 dev xenbr1 scope link 192.168.2.0/27 dev eth2 proto kernel scope link src 192.168.2.4 192.168.2.0/27 dev xenbr1 proto kernel scope link src 192.168.2.3 192.168.1.0/24 dev xenbr0

Is anyone frustrated by Network Manager? I wish CentOS just used the basic configuration files like the ones on BSD-style OSes. Those are so simple in comparison. Each time I reboot, it seems like the configuration file I create for Network Manager gets destroyed and replaced with a default file. Nothing in the default file would actually make sense on my network, so I'm not even really sure

Hi all, Somebody can explains me how can I configure ipsec-tools package to use private virtual ip address as an openswan does or some doc/howto about it??

Hello All I have looking for any specific answer for one thing. I have a virtualized Server with only one physical interface eth0 (WAN). To run OpenVPN i need to use DHCP server. And here is the question: is there a chance to run DHCP server on eth0:0 interface? Or it is impossible ? Thanks in advance. -- /Best Regards *Greg*/ UML Professional (Cert #251574932)

Hello all, I have a CentOS box that has a NIC (eth0) on which I defined 4 VLAN's (counting the NIC itself): eth0, eth0.1, eth0.2 and eht0.3. Initially the Cisco switch was not partitioned into VLAN's which means that the only VLAN running on it was the default one (VLAN 1). I have then played with VLAN's a bit on the switch and at this point have two: VLAN 1 (which is default and can

So far, OpenVPN has been working very well for me. Unfortunately, the iPhone doesn't have (yet?) an OpenVPN client, so I'm forced to work with what's available. The options are: L2TP, PPTP and IPSec. If you were to install a VPN endpoint on CentOS, which protocol would you prefer? The condition is to avoid shabby VPN servers that make the system less secure. I've seen some
