Watching Live OTA TV With MPlayer
Last month, I took you through how to set up VLC to watch live, OTA (over the air) broadcasts via a USB TV tuner. This month, let's take a look at how to do the same with MPlayer.
MPlayer is one POWERFUL multimedia powerhouse program. Did I mention that it was powerful? As with anything that wields that much power, it can sometimes present a level of complexity that is daunting, as it strives to cover as many multimedia bases as it can. In fact, MPlayer will often play files that other multimedia programs simply shrug at.
MPlayer is a multiplatform program, with versions for Linux, MacOS, and Windows. MPlayer is also "desktop agnostic" That means that it doesn't use either the Qt or GTK+ programming toolkits, opting instead for good, sound code that runs equally well regardless of which programming toolkit is employed.

How to install and configure Squid Proxy on Ubuntu 22.04
In this guide we will learn how to install and configure Squid Proxy server on a Ubuntu 22.04 server.
Squid is a caching proxy for the Web supporting HTTP, HTTPS, FTP, and more. It reduces bandwidth and improves response times by caching and reusing frequently-requested web pages. Squid has extensive access controls and makes a great server accelerator. It runs on most available operating systems.
Squids reverse proxy is a service that sits between the Internet and the webserver (usually within a private network) that redirects inbound client requests to a server where data is stored for easier retrieval. If the caching server (proxy) does not have the cached data, it then forwards the request on to the web server where the data is actually stored. This type of caching allows for the collection of data and reproducing the original data values stored in a different location to provide for easier access.
A reverse proxy typically provides an additional layer of control to smooth the flow of inbound network traffic between your clients and the web server.

Configuring SASL on Linux
“The two most significant challenges that server administrators face when attempting the SASL configuration on Linux or any other platform are the installation channel and the choice of the mechanisms you want to support with SASL.
You can install SASL using the tarball installation method or the UNIX package installation methods. Again, there is an array of mechanisms that SASL can support.
You can choose to support plaintext mechanisms such as LOGIN and PLAIN mechanisms. You can also opt for any type of shared secret mechanism. Shared secret mechanisms include CRAM-MD5, SCRAM, or DIGEST-MD5. Finally, Kerberos authentication protocol users may also choose GSSAPI for Kerberos 5 or KERBEROS_V4 for Kerberos version 4.
This article is specific and will discuss the SASL installation using the shared secret mechanism (CRAM-MD5). Again, this article will use the LDAP protocol. Thus, only attempt going through this guide once you have LDAP-SASL properly running in your systems.”
