Re: How to link the server configuration files to IPs?
In your case the "server" is OpenVPN and therefore your question is for OpenVPN community/documentation. The CentOS Streams do not provide openvpn. In the iptables rules I have mentioned the name of the NIC. How can OpenVPN recognize that the configuration files Server-1.conf , Server-2.conf and Se...

Re: A question about the virtual NIC
Delete what? All addresses? Set ipv4.addresses "" All changes by nmcli are permanent. In fact, some don't even show in action until you reload. (Reboot, or restart NetworkManager.service, or nmcli con down eth0 ; nmcli con up eth0 .) Hello, Thanks again. Delete the new IP address that was added to ...

Re: Why ping work with NIC IP not NIC name?
Hello, Thank you so much for your reply and time. I guess not. Please note, it did not work when I used the the name of the NIC: # ping -I enp0s8 google.com PING google.com (216.239.38.120) from 10.0.3.15 enp0s8: 56(84) bytes of data. But, it worked when I used the IP address of the same NIC: # ping...

How to link the server configuration files to IPs?
Hello, Suppose several IP addresses are set on a NIC and the name of the NIC is eth0 . For example, I have set 1.2.3.4 , 1.2.3.5 and 1.2.3.6 IP addresses on the eth0 . I want to launch several server configuration files for each IP. For example, for IP 1.2.3.4 , I want to launch Server-1.conf , Serv...

Re: A question about the virtual NIC
In which file does this command write the settings? How do I delete the added IP? In whatever file the NetworkManager does use for storing the config. We supposedly don't need to know. (The rationale is that the tools, like nmcli, do use proper syntax in file -- something that humans can fail to do...

Re: A question about the virtual NIC
Do you say that one can run three openvpn services on one interface/address? If true, then one can surely run nine openvpn services on the same address too. The use of more than one address on that one subnet is thus not necessary. It is possible to assign multiple addresses to one interface, just ...
