Hi, has anyone enabled using centos, the proliant functionality of "teaming" the two integrated network cards, to be seen as one by the network switch? This is available in a nice GUI in windows. but i have no idea how to do that on linux. -- ------------------------------------------------------------ Erick Perez Panama Sistemas Integradores de Telefonia IP y Soluciones Para Centros

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

My Centos 7 server has started to forget its IPv6 address on a reboot. This causes problems with services being unable to start up. It's easy enough to fix each time (ip addr add ...), but it would be nice to be able to convince it to retain that information. Presumably, there's a file somewhere under /etc/sysconfig that should contain this information - does anyone know where it should

Not sure what your use of multiple IPs is. . . but I'd probably use an interface alias instead of secondary. https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/s2-networkscripts-interfaces-alias.html

...ally we get the following error: RTNETLINK answers: No such process When we use ifup we get the following: Error: either "to" is a duplicate, or "10.1.1.1" is a garbage. A little discussion of this can be found here: http://www.centos.org/docs/5/html/5.1/Deployment_Guide/s1-networkscripts-static-routes.html and here: http://www.linuxquestions.org/questions/linux-networking-3/etc-init-d-networking-restart-errors-637610/ It does not help us, however. Any tips much appreciated. Cheers, Boris.

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

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
