similar to: ifenslave vs. /etc/sysconfig/network-scripts

I've made 3 CentOS 7 installation attempts to configure a simple firewall/router box with 2 nics. I got myself into a circular scenario where NetworkManager and firewalld and /etc/sysconfig/network-scrpts/ifcfg-***** were interfering or overwriting each other. Needed to perform ifdown enp3s7 on the internal LAN nic in order to make the external internet enp2s0 reach websites and ping

Hi, on our cluster we have 5 network interfaces. I was surprised to discover that the ifcfd-* files under /etc/sysconfig/networking and /etc/sysconfig/network-scripts were not the same. So I have searched a little bit, but I'm now confused: - the files under /etc/sysconfig/networking come from system-config-network. - the files under /etc/sysconfig/network-scripts are read by the

Does Centos 7 use /etc/sysconfig/network or is this replaced by some systemctl set of commands. For example I know to set my host name with: hostnamectl set-hostname nevia.htt-consult.com But I don't know if this is the same as cat <<EOF>/etc/sysconfig/network || exit 1 NETWORKING=yes HOSTNAME=nevia.htt-consult.com EOF

I let Network Manager control the interfaces on my two or three C7 boxes. I used nmtui to set the hostname, and MAC and IP addresses (the MAC addresses need to be updated if you clone a machine in VMware) interactively. That's not

Setting up bonding in active-backup mode 1 (using ARP monitoring) on a server, it looked OK, but pulling the active link cable didn't actually work, it didn't fail over. Eventually with manual playing around with modprobe, ifconfig, ifenslave, etc., a solution was stumbled upon: enslave the eth1 device before eth0, and all is good. Why this should matter is a puzzle - I could not find

I have two routers for different subnets and I'd like to set up different eth0 configurations depending on which one I have the network plugged into. However, it seems that every time I let system-config-network do its thing it forces all the eth0 configurations to be the same (hard-links them all to the one in the "default" profile). I'd also like to have virtual interfaces

Greetings: i have a pretty stock CentOS 5 machine with ports 80 and 22 exposed, so my /etc/sysconfig/iptables file is pretty standard/straightforward. my question is: how is this config file initially generated? i'd like to re-create it, and add a couple of rules .... so i don't want to lose what's in there already. i see that my /etc/sysconfig/system-config-securitylevel has

Hello, I found different ways to define the hostname ... this HOSTNAME="host.domain.tld" or this: HOSTNAME="host" DOMAIN="domain.tld" what is the correct way? Thanks, Walter

You need to disable firewalld and install iptables, if you really want use old way: https://www.certdepot.net/rhel7-disable-firewalld-use-iptables/ Firewalld is preferred way.

The last two router/firewall servers I had used Slackware and Gentoo. I'm used to writing complete and explicit iptables rules; however, when I set up /etc/sysconfig/iptables in CentOS 7 my usual syntax is unusable. For example, I'm used to stating postrouting masquerade as: /usr/sbin/iptables -t nat -A POSTROUTING -o eth0 -s 10.10.10.0/24 -j MASQUERADE But when I use the rule above,
