From network-scripts to NetworkManager on a router : questions
Hi,
I'm running CentOS 7 on all my servers, in three different contexts :
1. simple local server
2. public facing server
3. router/gateway/firewall
I'm currently in the process of moving my KISS-style
network-scripts-style configurations to something more orthodox based on
NetworkManager.
Scenarios (1) and (2) caused no problems, but (3) is giving me some
headache. Let me

I would like to do that very much, only NetworkManager makes you jump through
burning loops to do so.

CentOS 7.5 (1804) and NetworkManager
Hi,
I'm running CentOS on all kinds of setups: servers, workstations,
desktops and laptops.
Up until now, I'm only using NetworkManager on laptops, since it makes
sense to use it there. On servers and desktop clients, I usually remove
it and configure the network "traditionally" by simply editing
/etc/sysconfig/network-scripts/ifcfg-whatever, /etc/resolv.conf,
/etc/hosts,

Disappearing Network Manager config scripts
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

The truth is a lot of us run servers that don't need to have their
network "managed" by Networkmanager.
We just need to set an IP address, subnet mask, gateway, and DNS servers
and we will never be changing that configuration ever

which firewall to automatically block bandwidth abusers?
Hi,
I'm looking for a firewall (preferably on Linux / UNIX) that could
automatically block bandwidth abusers as soon as a connection goes
over a certain speed, or limit - i.e. either more than say 3Mb/s or
10GB in a giving period (like weekly / monthly).
But, I need it to block the IP to, or where the traffic comes from, or
goes to. i.e. a user logs into a web server and upload a LOT of

nmcli: unwanted secondary ip-address
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:

NetworkManager fights with DHCP-only backup NIC
We ship servers to remote sites, which are rarely staffed with techs familiar with Linux. We have them tell us the static IP configuration for the box before we ship it, then we set it up for them here and ship it out to the site, where they just plug it in, turn it on, and walk away.
That?s the ideal, anyway.
What often happens in reality is either:
1. They give us incorrect static IP info,

How is that better than

Again, I?m not really after a way to make this work without NetworkManager. We?ve already got that. What I want is a way to tell

how do I find out which nameserver returns a DNS query?
Hi all
If I do a "dig mydomain.co.za" from a Linux server, how do I know which
DNS nameserver returns the queries?
I seem to have a faulty DNS server, but can't see which one, so I want
to find out which nameserver (if there's 4 - ns1.myserver, ns2.myserver,
ns3.myserver & ns4.myserver) returns the queries?

Unable to edit resolv.conf
Hello,
I changed ISPs and need to update name servers in resolv.conf.
I have tried nano, gedit, Webmin, system-config-network and it won't allow
me to make the changes.
I have Network Manager turned off and when I enable it , eth0 and eth1 have
no entries.
I enabled it, added the connections, but still no changes.
I'm stuck
