Connect to the Internet Repository Server, by the following commands wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm & rpm -ivh epel-release-latest-7.noarch.rpm 2. After Connecting to the Repository Server, Install Packages with
Different Between Baseband and Broadband
Differentiating Between Baseband and Broadband Signaling Two types of signaling methods are used to transmit information over network media: baseband and broadband. Before we get any further into 802.3 standards we should clarify the difference between the two. Baseband Baseband transmissions typically use digital signaling over a single wire; the transmissions themselves take the form
INTERNET CONTROL MESSAGE PROTOCOL
ICMP is a networking protocol developed to analyse the connectivity between source and destination hosts. The structure of ICMP datagram as follows Data (32 bytes by default) Sequence No: – Since it is sending data repeatedly, ICMP itself assings a sequence number to identify the segment of data Identifier – It is very close to port
su command and sudo command in linux
su – Substitute User If one user needs to login as another user in the same CLI(shell) eg: su -l user-name Note: Root user can login as any of the other user without needing the password of the other users Normal user can login as any of the other user with password In some cases
Blazing fast failure detection – BFD (Part-1)
Actually BFD stands for Bidirectional Failure Detection, but its not catchy so I chose to call it blazing-fast failure detection. Let us understand what it does and what is so cool about it. If you had 2 routers connected to a switched network and the router needed to maintain neighbour relationship between themselves. What will
Why you need NTP (Network Time Protocol)?
If you were to read news in a News paper and find out when that news took place you would look at the date of publishing on the News paper. We need an anchor, a constant, that we all agree to follow in order to relate to the events happening in our lives. similarly when we talk about IT infrastructure a good IT Engineer will also make sure he checks that time when a particular event happen.
Future communication technology
We are approaching the time when we will be able to communicate faster than the speed of light. It is well known that as we approach the speed of light, time slows down. Logically, it is reasonable to assume that as we go faster than the speed of light, time will reverse. The major consequence of this for Internet protocols is that packets will arrive before they are sent. This will have a major impact on the way we design Internet protocols. This paper outlines some of the issues and suggests some directions for additional analysis of these issues.
Creating a Local YUM Repository with ISO
In Order to install or Update software in RHEL we need to connect to RHN (RedHat Network). By creating Local Repository we can install software from our own device. It saves things like bandwidth and time. All we need is an iso image (CD/DVD image). Download the iso file from redhat.com and place it in /iso directory To
Notes – Types of VPN
PPTP
This is the most common and widely used VPN protocol. They enable authorized remote users to connect to the VPN network using their existing Internet connection and then log on to the VPN using password authentication. It also doesn’t provide encryption and it relies on PPP protocol to do this.
How-to change SSH port number in RHEL-7
SSH is a networking protocol used for accessing the CLI(shell) remotely with applications. In RHEL7, ssh will be by default running as a daemon service called sshd in port 22. In this blog i want to show you how to secure the ports of SSH by changing it.
