Installing Dkms On Centos 7

To install Veeam Agent for Linux:

For CentOS 7, ensure that the system has the correct Linux kernel sources from the CentOS repositories: $ sudo yum install -y kernel-devel-$(uname -r) kernel-headers-$(uname -r) Update the repository cache and install the driver using the nvidia-driver-latest-dkms meta-package. Turn on and install EPEL Repo on a CentOS 7.x You must install dkms for registering the NVIDA kernel module with DKMS: $ sudo yum -y install epel-release $ sudo yum -y install dkms. I am running now NVIDIA card, simply dont install dkms if that is the case, you will still get the driver regardless But if you are desperate, check the headers match your kernel version. Sometimes, when the header is not install along with your kernel, then you do install it at latter time, the system will offer a header that is not match with.

1. Download the Veeam software repository installation package (veeam-release) from the Veeam Download page, and save the downloaded package on the computer where you plan to install the product.

1. Navigate to the directory where you have saved the veeam-release package and install the package with the following commands:

For CentOS / RHEL / Oracle Linux / Fedora

For openSUSE / SLES

For Debian / Ubuntu

• Packman repository (for openSUSE). To learn more, see Installing dkms in openSUSE.

For SLES, the dkms package is not available in the Packman repository. You must use the package intended for openSUSE. To learn more, see this Veeam KB article.

• Extended kernels, such as kernel-pae, kernel-uek and other, require appropriate kernel-devel packages to be installed, for example, kernel-pae-devel, kernel-uek-devel, and so on.

Version of the kernel-devel package must match your current kernel version. To check your current kernel version, run the uname -r command.

[For RHEL and derivatives] If the yum package manager installs packages that do not match your current kernel version, you should either update your system or fetch older versions of the required packages from the CentOS Vault repository.

1. Make sure that you have allowed unsupported modules. To learn more, see this SUSE webpage.

Introduction

I'm tired of OpenVPN quirks and configuration issues across my devices.Additionally, I've been planning to try out WireGuard for some time now, afterhearing praises from some different people along my way.

I set up a new CentOS box to act as the VPN server, and the client in myguide is, as usual, running Arch Linux.

The section headers below tells you whether the work is on the CentOS server(server) or the Arch Linux client (client).

Server

This host is running CentOS

The installation steps are based on https://www.wireguard.com/install/ andmay have been updated since time of writing this post.

Add the EPEL (Extra Packages for Enterprise Linux) RPM repo andinstall WireGuard and utilities

Create an empty server config file with proper permissions

Configure the wireguard network interface. Here we are using the output of wg genkey directly. The PrivateKey option in the wg-quick configuration file also accepts a file path to a file containing the private key, if that should be more desirable.

Save configuration to a file Hp dc7800 pci serial port driver windows 10.

Take note of the public key of the server. All of the clients will need it in order toestablish a wireguard connection to this server.

Client

This example client host is running Arch Linux. If you are running CentOS on your client too, repeat the installation steps as described in the previous step instead.

Install wireguard packages.

Create a folder only accessible by root and generate a private key

The contents of private.key will now look something like this:

This is a private key, hence, a secret that should not be shared with anyone.In contrast to the public key which is not considered secret and can evenbe sent over an unencrypted channel.

The public key has to be registered on the server in a later step. Take note of howto extract it:

Create a wg-quick configuration file which makes it easier to bring up anddown one or more WireGuard interfaces

Install Virtualbox 6.1 On Centos 7

• Remove IPv6 configuration if you're not using it.
• Replace the Address with the IP address intended for this client, and theprefix for the subnet it belongs to.
• Replace the value of PrivateKey with the contents of the client private.key file.
• Replace the value of PublicKey with the public key of the server that wasdetermined in a previous section.
• Replace the Endpoint with the public IP or hostname of the server.

Server firewall configuration

If you're not running firewalld, this step may be skipped.

Create a new firewalld service definition for WireGuard

Enable the custom WireGuard service in firewalld

Enable masquerading

Reload firewalld and take a look at the zone configuration

Enable IPv4 forwarding, and, if applicable, IPv6 forwarding as well.

Make sysctl settings persistent across reboots

Installing Dkms On Centos 7 Command

Start the wireguard client process on the server

Letting VPN clients connect to each other (optional)

Add wireguard interface to the internal firewalld zone

Enable masquerading

Enable the services you'd like to be available on this network using firewall-cmd --zone=internal --add-service [name]. Remember to add the flag --permanent when it works. So easy to forget.

Server - Allow client to connect

Now, back in the server configuration file, add the client public key and the IP's it should be allowed to register with on the server.Copy the public key from the client and paste it into the server configuration, like below.

Restart the server. No errors should be thrown.

Client - Attempt to connect to server

Attempt to connect to the server

See if you are able to send and receive traffic, and at the same time checkyour IP address

Complete configuration
