Then within the same directory run ./configure command. This will be responsible for getting ready to build the software on your system. It makes sure all of the dependencies for the rest of the build and install process are available, and finds out whatever it needs to know to use those dependencies.
Now that the software is built and ready to run, the files can be copied to their final destinations. The make install command will copy the built program, and its libraries and documentation, to the correct locations.
Another option is UFW, or Uncomplicated Firewall. UFW is a front-end to iptables that aims to provide a more user-friendly interface than other firewall management utilities. UFW is well-supported in the Linux community, and is typically installed by default on many distributions.
This tutorial is going to show you how to run your own VPN server by installing OpenConnect VPN server on CentOS 8/RHEL 8. OpenConnect VPN server, aka ocserv, is an open-source implementation of the Cisco AnyConnnect VPN protocol, which is widely used in businesses and universities. AnyConnect is an SSL-based VPN protocol that allows individual users to connect to a remote network.
I particularly like the fact that compared to other VPN technologies, it is very easy and convenient for the end-user to use OpenConnect VPN. Whenever I install a Linux distro on my computer and want to quickly unblock websites or hide my IP address, I simply run the following command to connect to my OpenConnect VPN server.
Following this tutorial, i can setup ocserv on a centos8 in google cloud. the connection between anyconnect client and vpns1 ethernet is good. however, the forwarding between vpns1 ethernet and etho in host looks never work, despite I tried many firewalld/iptables rules as following. can someone give me some suggestions to solve this problem bothered me several days. Thanks a lot in advance!
As you know nowadays Iranian people are in extremely heavy censorship firewall. Almost every VPN connection failed. I configure ocserver as you instruct in both ubuntu and centos. both are work absolutely well with windows client of openconnect.
For Oracle ASR to work, both Oracle PCA management nodes must be running TinyProxy version 1.8.3 or later. Verify the installed version and upgrade if necessary. Configure TinyProxy according to the procedure in this section.
In this tutorial, we will learn step-by-step how to install, optimize and configure Zabbix Proxy 6.0 LTS or 6.2 standard release on RHEL and RHEL based Linux distributions: CentOS 9 or 8 / RHEL 9 or 8 / Oracle Linux 9 or 8 / Alma Linux 9 or 8 / Rocky Linux 9 or 8.Zabbix proxy is a service that can collect performance and availability data from the end devices on behalf of the Zabbix server.You can use proxy to monitor remote locations behind the firewall or locations that have unreliable communication and to offload the Zabbix server in large environments.if(typeof ez_ad_units!='undefined')ez_ad_units.push([[728,90],'bestmonitoringtools_com-medrectangle-3','ezslot_8',115,'0','0']);__ez_fad_position('div-gpt-ad-bestmonitoringtools_com-medrectangle-3-0');Zabbix proxy architecture exampleEnough of talk lets do some work! We will install the latest version of the Zabbix proxy 6 on on CentOS, RHEL, Oracle/Alma/Rocky Linux and make the key optimizations so that your proxy performs better.This guide is for installing Zabbix Proxy on CentOS/RHEL while guides for installing Zabbix monitoring system (Server) on various Linux distribution can be found on these links: CentOS/RHEL, Ubuntu, Debian, Rasbian (Raspberry Pi).ContentsStep 1: Set SELinux to permissive modeStep 2: Configure firewallStep 3: Install Zabbix Proxy on CentOS/RHELStep 4: Configure databaseStep 5: Zabbix Proxy configurationStep 6: Start and enable Zabbix Proxy serviceStep 7: Register Zabbix Proxy in the Zabbix frontendStep 8: Configure hosts in Zabbix to be monitored by a Proxy ServerStep 7: Configuring PSK encryption on Zabbix proxy (optional)Step 8: Optimizing Proxy server (optional)Step 9: Optimizing MySQL database (optional)Step 10: How to manage Proxy and MySQL serviceStep 11: Understanding Active vs Passive Zabbix Proxy modStep 12: Learn about common Zabbix Proxy errorsStep 1: Set SELinux to permissive modeIt is recommended to have SELinux in permissive mode unless you know how to fix its issues:setenforce 0 && sed -i 's/^SELINUX=.*/SELINUX=permissive/g' /etc/selinux/configStep 2: Configure firewallfirewall-cmd --add-service=http,https --permanentfirewall-cmd --add-port=10051/tcp,10050/tcp --permanentfirewall-cmd --reloadStep 3: Install Zabbix Proxy on CentOS/RHELBefore you start installing proxy, keep in mind that your Zabbix proxy version must match the server version!
Note that Zabbix is using compression for communication with Proxies. Compression improves performance because it drastically reduces network traffic.However, this may cause some problems in environments that have security devices (IDS/IPS or NGFW) installed as they can drop network packets if they detect compression in the network stream. To avoid that problem, make sure the application definitions on the security devices are up-to-date, and if you have any problems, contact your device vendor.Checking logs on the Proxy serverIf you experience a problem with the proxy you can check last 500 lines of the log with the command:tail -500 /var/log/zabbix/zabbix_proxy.logThank you for reading.
When picking which disks to install to make sure you select the correct disk and leave the other completely untouched, in my example my screen looks like the following. This lets the installation install to the larger drive and it will leave our cache disk available to use during the Websense install.
From here you should be able to SSH to your new server, there are a few things we need to do before we even think about installing the Websense components. As I mentioned at the beginning of this tutorial do NOT update your installation at this point.
Privoxy is available for Linux, DD-WRT, OpenWrt, Windows, macOS, OS/2, BeOS, etc. Privoxy makes it into our list because it is relatively easy to install, configure and get running. The default configurations are sufficient for locally defined exceptions and locally defined filters. The concept of actions in Privoxy gives you, as the user, great control to manipulate data streams between remote sites and the browser. Some Privoxy actions available for you include blocking websites, managing cookies, URLs, or grouping URLs using regular expressions.
It works great with all major web servers, including Apache, Nginx, Varnish, and can be installed in all major distributions. It also allows you to place a reverse proxy in front of it, increasing security and giving you more configuration options.It is an excellent place to learn to configure and set up self-hosted proxy web servers. SwiperProxy has a simple procedure to run it as a self-containing proxy or as a daemon.
But to get started, you should learn to install a configure some popular self-hosted servers in a virtual environment. Proxy servers allow you greater control of your network and internet infrastructure.
Kubernetes clusters can be configured in many different ways. Before we caninstall the Linkerd control plane, we need to check and validate thateverything is configured correctly. To check that your cluster is ready toinstall Linkerd, run:
Since it is a kernel module it is usually not something users installthemselves. Individual users and system administrators might however want tomanage the application profiles which define what each application is allowed todo by editing the files in /etc/apparmor.d/.
cloud-init is a widely used approach to customize a Linux VM as it boots for the first time. You can use cloud-init to install packages and write files, or to configure users and security. Because cloud-init is called during the initial boot process, there are no additional steps or required agents to apply your configuration. For more information on how to properly format your #cloud-config files or other inputs, see the cloud-init documentation site. #cloud-config files are text files encoded in base64.
cloud-init also works across distributions. For example, you don't use apt-get install or yum install to install a package. Instead you can define a list of packages to install. cloud-init automatically uses the native package management tool for the distro you select.
cloud-init cannot process Azure extensions, so WALA is still required in the image to process extensions, but will need to have its provisioning code disabled, for endorsed Linux distros images that are being converted to provision by cloud-init, they will have WALA installed, and setup correctly.
The following example creates a VM named centos74 and creates SSH keys if they don't already exist in a default key location. To use a specific set of keys, use the --ssh-key-value option. Use the --custom-data parameter to pass in your cloud-init config file. Provide the full path to the cloud-init.txt config if you saved the file outside of your present working directory. 2ff7e9595c
