Cisco to MikroTik – command translation – OSPF

In the world of network engineering, learning a new syntax for a NOS can be overwhelming if you need a specific set of config in a short timeframe. The command structure for RouterOS can be a bit challenging if you are used to Cisco CLI commands.

If you’ve been in networking for a while, there’s a good chance you started with Cisco gear and so it is helpful to draw comparisons between the commands, especially if you are trying to build a network with a MikroTik and Cisco router.

This is the second post in a series that creates a Rosetta stone essentially between IOS and RouterOS. We plan to tackle  other command comparisons like MPLS, VLANs and basic operations to make it easier for network engineers trained in Cisco IOS to successfully implement Mikrotik / RouterOS devices.

While many commands have almost the exact same information, others are as close as possible. Since there isn’t always an exact match, sometimes you may have to run two or three commands to get the information needed.

IDG Contributor Network: China to block SD-WAN and VPN traffic by Jan. 11

A new Chinese policy going into effect next week, will have profound impact on businesses relying on Internet VPN or SD-WAN access within China.According to a notice from China Telecom obtained by SD-WAN Experts, the Chinese Government will require commercial Chinese ISPs to block TCP ports 80, 8080, and 443 by January 11, 2018. Port 80 is of course the TCP port commonly used for carrying HTTP traffic; 8080 and 443 are used for carrying HTTPS traffic. Commercial ISP customers interested in maintaining access to those ports must register or apply to re-open the port through their local ISP.  The news, first reported by Bloomberg July, was expected to be implemented by February, 2018. This is the first time a specific date has been provided for the action.To read this article in full, please click here

Stuff The Internet Says On Scalability For January 5th, 2017

Hey, it's HighScalability time: 


All we know about how the universe works. The standard model and mind blowing video.

 

If you like this sort of Stuff then please support me on Patreon. And I'd appreciate your recommending my new book—Explain the Cloud Like I'm 10—to anyone who needs to understand the cloud (who doesn't?). I think they'll like it. Now with twice the brightness and new chapters on Netflix and Cloud Computing.

France goes after companies for deliberately shortening life of hardware

Printer manufacturers “deliberately shorten the life of printers and cartridges,” a French environmental and consumer protection group claims. That's against the law in France, and government prosecutors have agreed to investigate the claims.If the lawsuit against the printer company, Japan-based Epson, is proven, the firm could be found guilty of breaking a little-known French law that stipulates vendors can’t purposefully lower the lifespan of a product to ramp up replacement rates.Also on Network World: Top 10 data center predictions: IDC A conviction could be significant for tech hardware manufacturing overall. Nabbing Epson would likely affect not only how hardware is built and sold in France, but it also could mean laws get adopted in other European territories —individual nations are involved in the functioning of the EU bloc overall.To read this article in full, please click here

Technology Short Take 92

Welcome to Technology Short Take 92, the first Technology Short Take of 2018. This one was supposed to be the last Tech Short Take of 2017, but I didn’t get it published in time (I decided to spend time with my family instead—some things are just more important). In any case, hopefully the delay of one additional week hasn’t caused any undue stress—let’s jump right in!

  • Lindsay Hill walks through using Telegraf, InfluxDB, and Grafana to monitor network statistics.
  • Via Ivan Pepelnjak, I found this article by Diane Patton at Cumulus Networks talking about container network designs. The article is a bit heavy on pushing the Host Pack (a Cumulus thing), but otherwise provides a good overview of several different possible container network designs, along with some of the criteria that might lead to each design.
  • Erik Hinderer takes a stab (based on his field experience) at estimating how long it takes to upgrade VMware NSX. Erik’s figures are just estimates, of course; actual values will be determined based on each customer’s specific environment.
  • This post is a bit older, but covers a challenge faced by cloud-native darling Netflix—how does one, exactly, identify which application used which IP address Continue reading

5 tips to learn Docker in 2018

As the holiday season ends, many of us are making New Year’s resolutions for 2018. Now is a great time to think about the new skills or technologies you’d like to learn. So much can change each year as technology progresses and companies are looking to innovate or modernize their legacy applications or infrastructure. At the same time the market for Docker jobs continues to grow as companies such as Visa, MetLife and Splunk adopt Docker Enterprise Edition ( EE) in production. So how about learning Docker in 2018 ? Here are a few tips to help you along the way.

 

1. Play With Docker: the Docker Playground and Training site

 

Play with Docker (PWD) is a Docker playground and training site which allows users to run Docker commands in a matter of seconds. It gives the experience of having a free Linux Virtual Machine in browser, where you can build and run Docker containers and even create clusters. Check out this video from DockerCon 2017 to learn more about this project. The training site is composed of a large set of Docker labs and quizzes from beginner to advanced level available for both Developers and IT pros at  training. Continue reading

Un-Nintendo Consequences: Protect Your Devices from Attacking Gaming Networks

This holiday season, we published a buying guide for “smart toys,” as well as steps you could take to secure them once they were home. As we start the new year, it’s a good time to revisit Holiday DDoS Attacks: Targeting Gamers (Plus Five Things You Can Do). Last year Ryan Polk wrote, “gaming networks are most often targeted by DDoS attacks, as the end of year holidays usually bring many users online who are eager to try out their new games and systems.” He included the following helpful tips.

Five actions to protect your devices from becoming bots:

  • Create and use strong passwords for all your devices. Do not use the default. This is especially important for smart devices, routers, and other devices with which you may not interact directly.
  • Update your devices! Software is often patched to remove known vulnerabilities, greatly strengthening your defenses.
  • Monitor your devices. If a device is acting strangely, investigate it. One example is bounced email messages. If email messages are not reaching their destination, your device could be infected and sending spam as a part of a botnet.
  • Run anti-virus scans and use other security tools to find and remove malicious software.
