Easy and Simple 11 Steps to configure Cisco DSL Router

Today I am going to talk about the easy and the simple 11 steps to configure the DSL configuration. Below is the basic setup of the DSL router in the network.


Fig 1.1- Cisco DSL Topology
The above shown diagram is just an example of DSL connection and below is the sample configurations on the cisco routers. Let's talk about the 11 steps to configure the Cisco DSL router now.


Step 1
Configure service time stamp to properly log and display debug output in the troubleshooting section.

ttlbits_router#configure terminal
ttlbits_router(config)#service timestamps debug datetime msec
ttlbits_router(config)#service timestamps log datetime msec
ttlbits_router(config)#end

Step 2
Disable the logging console on your Cisco DSL Router to suppress console messages that may be triggered while you are configuring the router.

ttlbits_router#configure terminal
ttlbits_router(config)#no logging console
ttlbits_router(config)#end

Step 3
Configure IP routing, IP subnet−zero, and ip classless to provide flexibility in routing configuration options.

ttlbits_router#configure terminal
ttlbits_router(config)#ip routing
ttlbits_router(config)#ip subnet−zero
ttlbits_router(config)#ip classless
ttlbits_router(config)#end

Step 4
Configure an IP address and subnet mask on the Cisco DSL Router Ethernet interface. Enable NAT inside on the Ethernet interface.

ttlbits_router#configure terminal
ttlbits_router(config)#interface ethernet 0
ttlbits_router Continue reading

The History of Email

The History of Email

This was adapted from a post which originally appeared on the Eager blog. Eager has now become the new Cloudflare Apps.

QWERTYUIOP

— Text of the first email ever sent, 1971

The ARPANET (a precursor to the Internet) was created “to help maintain U.S. technological superiority and guard against unforeseen technological advances by potential adversaries,” in other words, to avert the next Sputnik. Its purpose was to allow scientists to share the products of their work and to make it more likely that the work of any one team could potentially be somewhat usable by others. One thing which was not considered particularly valuable was allowing these scientists to communicate using this network. People were already perfectly capable of communicating by phone, letter, and in-person meeting. The purpose of a computer was to do massive computation, to augment our memories and empower our minds.

Surely we didn’t need a computer, this behemoth of technology and innovation, just to talk to each other.

KEMP Presented Some Interesting Features at NFD16

KEMP Technologies presented at Network Field Day 16, where I was privileged to be a delegate. Who paid for what? Answers here.


Three facets of the KEMP presentation stood out to me:


The KEMP Management UI Can Manage Non-KEMP Devices

KEMP's centralized management UI, the KEMP 360 Controller, can manage/monitor other load balancers (ahem, Application Delivery Controllers) including AWS ELB, HAProxy, NGINX and F5 BIG-IP.

This is pretty clever: If KEMP gets into an enterprise, perhaps because it's dipping a toe into the cloud at Azure, they may manage to worm their way deeper than would otherwise have been possible. Nice work, KEMPers.

VS Motion Can Streamline Manual Deployment Workflows

KEMP's VS Motion feature allows easy service migrations between KEMP instances by copying service definitions from one box to another. It's probably appropriate when replicating services between production instances and when promoting configurations between dev/test/prod. The mechanism is described in some detail here:


The interface is pretty straightforward. It looks just like the balance transfer UI at my bank: Select the From instance, the To instance, what you want transferred (which virtual service) and then hit the Move button. The interface also sports a Copy button, so in that Continue reading

BrandPost: SD-WAN Benefits: More Than Eliminating MPLS

Most of the discussion to date on the benefit of SD-WANs has focused on how an SD-WAN enables a network organization to reduce or eliminate its spend on expensive MPLS circuits.That is clearly an important benefit. However, as many early adopters of SD-WANs can attest to, SD-WANs have other important benefits.I am going to use this blog to summarize an interview I recently had with an IT professional who is in the midst of rolling out an SD-WAN solution. As described below, the benefits of the new solution include better performance, better visibility and the reduced cost and complexity that comes from removing Cisco routers.To read this article in full or to leave a comment, please click here

A New API Binding: cloudflare-php

A New API Binding: cloudflare-php

A New API Binding: cloudflare-php

Back in May last year, one of my colleagues blogged about the introduction of our Python binding for the Cloudflare API and drew reference to our other bindings in Go and Node. Today we are complimenting this range by introducing a new official binding, this time in PHP.

This binding is available via Packagist as cloudflare/sdk, you can install it using Composer simply by running composer require cloudflare/sdk. We have documented various use-cases in our "Cloudflare PHP API Binding" KB article to help you get started.

Alternatively should you wish to help contribute, or just give us a star on GitHub, feel free to browse to the cloudflare-php source code.

A New API Binding: cloudflare-php

PHP is a controversial language, and there is no doubt there are elements of bad design within the language (as is the case with many other languages). However, love it or hate it, PHP is a language of high adoption; as of September 2017 W3Techs report that PHP is used by 82.8% of all the websites whose server-side programming language is known. In creating this binding the question clearly wasn't on the merits of PHP, but whether we wanted to help drive improvements to the developer experience for Continue reading

Connecting Indigenous Communities

Internet access is often a challenge associated with developing countries. But while many of us in North America have the privilege of access at our fingertips, it’s still a huge barrier to success for many rural and remote Indigenous communities in Canada and the United States.

According to the 2016 Broadband Progress Report, 10% of Americans lack access to broadband. The contrast is even more striking when you look at Internet access in rural areas, with 39% lacking access to broadband of 25/4Mbps, compared to 4% in urban areas.

Many Canadian rural and remote communities face similar access issues. In December 2016, the Canadian Radio-television and Telecommunications Commission (CRTC) set targets for Internet service providers (ISPs) to offer customers in all parts of the country broadband at 50/10Mbps with the option of unlimited data. CRTC estimates two million households, or roughly 18% of Canadians, don’t have access to those speeds or data.

Let those figures sink in for a minute. Today in 2017, millions of people in North America still don’t have access to broadband Internet.

It’s an even harder to pill to swallow when you realize how disproportionately and gravely it affects indigenous communities, many of which are Continue reading

Worth Reading: Distrusting Symantic Certificates

At the end of July, the Chrome team and the PKI community converged upon a plan to reduce, and ultimately remove, trust in Symantec’s infrastructure in order to uphold users’ security and privacy when browsing the web. This plan, arrived at after significant debate on the blink-dev forum, would allow reasonable time for a transition to new, independently-operated Managed Partner Infrastructure while Symantec modernizes and redesigns its infrastructure to adhere to industry standards. This post reiterates this plan and includes a timeline detailing when site operators may need to obtain new certificates. —Devon O’Brien, Ryan Sleevi, Andrew Whalley @ Google Security

Azure Stack Finally Takes Microsoft Public Cloud Private

Microsoft announced Azure Stack at its Ignite event in September 2016 and soft-launched Azure Stack at its Inspire event in July, when it announced that the private cloud solution was available for customer orders. The first wave of Microsoft’s Azure Stack system partners – Dell EMC, Hewlett Packard Enterprise, and Lenovo – plan to ship their certified solutions to customers in September. We will be surprised if Microsoft does not announce first customer shipments with those vendors at Microsoft’s Ignite event in late September.

Azure Stack with compete with other hybrid private cloud frameworks, such as OpenStack, Cloud Foundry, HPE’s …

Worth Reading: BlueBorne

Bluetooth is ubiquitous, commonly connecting accessories like headsets and keyboards, but is also used throughout the brave new Internet of Things (IoT) world. An attacker exploiting these BlueBorne vulnerabilities can mount a man-in-the-middle attack, or even take control of a device without the user even noticing it. The vulnerabilities were discovered by a security company called Armis earlier this year. Researchers reached out to the companies responsible for vulnerable implementations that lead to the coordinated disclosure (and patches) on September 12. —Andrei Robachevsky @ The Internet Society

A Day in the Life of a Docker Admin

About two months ago, we celebrated SysAdmin Day and kicked off our learning series for IT professionals. So far we’ve gone through the basics of containers and how containers are delivering value back to the company through cost savings. Now we begin the next stage of the journey by introducing how to deploy and operate containerized applications.

For the next few weeks, we are going to relate typical IT administrative tasks that many of you are familiar with to the tasks of a Docker admin. In the end, containerized applications are still applications and it is still primarily the responsibility of IT to secure and manage them. That is the same regardless of if the application runs in a container or not.

In this “A Day in the LIfe of a Docker Admin” series, we will discuss how common IT tasks translate to the world of Docker, such as:

  • Managing .NET apps and migrating them off Windows Server 2008
  • How networking with containers work and how to build an agile and secure network for containers
  • How to achieve a secure and compliant application environment for any industry
  • Integrating Docker with monitoring and logging tools

As a first step, let’s make Continue reading
