Link: Set Up SSH Tunneling on a Linux / Unix / BSD Server To Bypass NAT

I’m a new Linux / Unix system user. How can I set encrypted tunnel between my desktop/laptop computer and server in a remote data center to bypass the limits in a network? How do I create a reverse SSH tunnel on Unix-like systems?

SSH tunnelling can be thought as a poor-man’s-VPN. It is handy in situations where you would like to hide your traffic from any body who might be listening on the wire or eavesdropping. You can use such tunnel between your computer and your Unix/BSD/Linux server to bypass limits placed by a network or to bypass NAT, and more.

Link: 10 SCP Commands to Transfer Files/Folders in Linux

Linux administrator should be familiar with CLI environment. Since GUI mode in Linux servers is not a common to be installed. SSH may the most popular protocol to enable Linux administrator to manage the servers via remote in secure way. Built-in with SSH command there is SCP command. SCP is used to copy file(s) between servers in secure way.

Link: Configure “No Password SSH Keys Authentication” with PuTTY on Linux Servers

SSH (Secure SHELL) is one of the most used network protocol to connect and login to remote Linux servers, due to its increased security provided by its cryptographic secure channel established for data flow over insecure networks and its Public Key Authentication.

While using passwords to login to remote servers can provide a less secure to system security, because a password can be brute-force cracked, SSH Public Key Authentication provides the best secure method to perform distance logins, because it’s almost impossible to decipher the key and the private key guarantees that the sender it’s always who it claims to be.

This article will show you how you can generate and use SSH Keys from Windows based platforms using Putty client to automatically perform remote logins on Linux servers without the need to enter passwords.

Link: Review of the TBS MOI+ DVB S/S2 Satellite TV Linux Server – a bit like a HDHomeRun, but for Free-To-Air satellite signals

A couple of years ago, I acquired a HDHomeRun Dual device, and discovered how nice it was to be able to stream terrestrial TV signals to anywhere in my home via my local network. I set up a backend system so that I could record programs and enjoy watching them at my convenience. I wondered if it was also possible to do the same thing with the signals I received off my satellite dishes. So earlier this year I attempted to build a backend system that could receive free-to-air satellite signals and stream them to the various computers around my home, including the home theater PC’s that are connected to my HDTV receivers. Let’s just say that the first attempts didn’t work as well as I’d hoped. There is a huge learning curve, particularly if you’re not a programmer nor otherwise particularly geeky, and sometimes the hardware and the backend software just won’t cooperate.

Then I stumbled across a page on the TBS MOI+. I suspected that it might be able to accomplish what I’d been trying to do, and in a lot smaller package. So, I went online in an attempt to find some reviews on this device. To my surprise, little has been written about it, particularly in English. So, hoping to fill that gap, I contacted TBS and asked if they might be interested in providing a unit for review purposes. They graciously consented, and this review is the result. Just so you know, I did not promise to write only nice things about the unit, and I’m not getting paid anything for this review, beyond receiving the MOI+. So, this will be as honest of a review as I can make it.

Link: Setting Up DNS Server On CentOS 7

DNS, stands for Domain Name System, translates hostnames or URLs into IP addresses. For example, if we type www.unixmen.com in browser, the DNS server translates the domain name into its associated ip address. Since the IP addresses are hard to remember all time, DNS servers are used to translate the hostnames like www.unixmen.com to 173.xxx.xx.xxx. So it makes easy to remember the domain names instead of its IP address.

This detailed tutorial will help you to set up a local DNS server on your CentOS 7 system. However, the steps are applicable for setting up DNS server on RHEL and Scientific Linux 7 too.
