Link: 8 Cool Ways To Use SCP

The SCP protocol is a network protocol, based on the BSD RCP protocol, which supports file transfers between hosts on a network. SCP uses Secure Shell (SSH) for data transfer and utilizes the same mechanisms for authentication, thereby ensuring the authenticity and confidentiality of the data in transit. A client can send (upload) files to a server, optionally including their basic attributes (permissions, timestamps). Clients can also request files or directories from a server (download). SCP runs over TCP port 22 by default. Like RCP, there is no RFC that defines the specifics of the protocol.

SCP is an awesome tool. Learn it, Love it, Use it….

Link: 18 Examples to Learn Iptable Rules On CentOS

Iptable is the administration tool for IPv4 packet filtering and NAT. Iptables is used to set up, maintain, and inspect the tables of IPv4 packet filter rules in the Linux kernel. Several different tables may be defined.Each table contains a number of built-in chains and may also contain user-defined chains.Each chain is a list of rules which can match a set of packets. Each rule specifies what to do with a packet that matches. This is called a `target’,which may be a jump to a user-defined chain in the same table.

Link: How to speed up directory navigation in a Linux terminal

As useful as navigating through directories from the command line is, rarely anything has become as frustrating as repeating over and over “cd ls cd ls cd ls …” If you are not a hundred percent sure of the name of the directory you want to go to next, you have to use ls. Then use cd to go where you want to. Hopefully, a lot of terminals and shell languages now propose a powerful auto-completion feature to cope with that problem. But it remains that you have to hit the tabulation key frenetically all the time. If you are as lazy as I am, you will be very interested in autojump. autojump is a command line utility that allows you to jump straight to your favorite directory, regardless of where you currently are.

Link: How to Use a Raspberry Pi as a Local Web Server

The Raspberry Pi might look like a small, almost inconsequential computer, but don’t let looks deceive you. It is a fully functional Linux machine capable of performing a large variety of functions including acting as a local web server.

The most common setup for a Linux-based web server is a “LAMP” server, where LAMP stands for Linux, Apache, MySQL and PHP. The default operating system for the Pi is Linux, specifically Raspbian and it can also run Apache, as the web server; MySQL, as a database; and PHP, for server-side scripting.

Link: 9 commands to check hard disk partitions and disk space on Linux

In this post we are taking a look at some commands that can be used to check up the partitions on your system. The commands would check what partitions there are on each disk and other details like the total size, used up space and file system etc.

Commands like fdisk, sfdisk and cfdisk are general partitioning tools that can not only display the partition information, but also modify them.

Link: Mikogo: A Multi-platform Desktop Screen Sharing And Remote Access Software

Most of you have heard and used the LogMeIn service which is used to access a remote system screen via Internet or through native applications. We can use Logmein software to online meetings, remote IT supports, web conferences etc. Unfortunately, Logmein is now switched to paid version and the free service is no longer available. …..

Luckily, we have another application called Mikogo which will help us to access the Desktop and Mobile screens remotely via web and manage them from anywhere. Mikogo is a free for personal use and works well on almost all modern operating systems such as GNU Linux, Windows, Mac OS X, Android, and Web. It is very simple to use, you don’t need to be an expert at all to use it. All you need is a decent uninterrupted Internet connection on both side. Mikogo has intuitive and decent interface to work with, and offers similar features present in Logmein.

Link: Mount Windows Shares Permanently in Ubuntu Linux

This document describes how to mount CIFS shares permanently. The shares might be hosted on a Windows computer/server, or on a Linux/UNIX server running Samba. This document also applies to SMBFS shares, which are similar to CIFS but are deprecated and should be avoided if possible (link).

(This document does not describe how to host the shares yourself, only how to access shares that are hosted somewhere else. For hosting shares, use Samba.)

Link: How to set up Internet connection sharing with iptables on Linux

In this tutorial, I’ll explain how to share a single Internet connection among multiple devices on Linux. While consumer-grade WiFi routers have become mainstream nowadays, making this problem a non-issue, suppose you don’t have one at home. However, say you have a Linux box already assembled with a modem and a LAN card. The modem is connected to the Internet with a dynamic public IP address, and the LAN card connected to your switch/hub. Other devices (Linux/Windows PC, laptop) are connected to the switch without having any Internet connection. To share the Internet connection of the Linux box, you have to turn the box into a gateway, so that it can relay traffic to and from other devices.
