Getting to 10 Gbps using EoIP

The EoIP tunnel protocol is one of the more popular features we see deployed in MikroTik routers.  It is useful anywhere a Layer 2 extension over a Layer 3 network is needed and can be done with very little effort / complexity.  One of the questions that seems to come up on the forums frequently is how much traffic can an EoIP tunnel handle which is typically followed by questions about performance with IPSEC turned on. Answers given by MikroTik and others on forums.mikrotik.com typically fall into the 1 to 3 Gbps range with some hints that more is possible. We searched to see if anyone had done 10 Gbps over EoIP with or without IPSEC and came up empty handed. That prompted us to dive into the StubArea51 lab and set up a test network so we could get some hard data and definitive answers.

The EoIP protocol and recent enhancements

Ethernet over IP or EoIP is a protocol that started as an IETF  draft somewhere around 2002 and MikroTik developed a proprietary implementation of it that has been in RouterOS for quite a while. Continue reading

FierceEnterpriseCommunications: Plexxi CEO: The future of networking is photonic underlays
By Chris Talbot
As he approaches his first anniversary as CEO of next-generation networking vendor Plexxi, Rich Napolitano is talking about the future of networks, and they’re not going to be focused on software-defined networking technology. SDN will play a huge role, of course, but it’s an overlay technology. Plexxi is focused on redefining the underlay, and it’s using photonic technology to do it.

Network Computing: SDN’s Northbound Interface Evolves
By Dr. Jim Metzler
Software defined networking requires both northbound and southbound interfaces to facilitate communication between physical devices, the SDN software and applications running on the network. On the southbound side, standards such as OpenFlow define Continue reading

Misguided House bill could make cars less safe

Car owners could face more danger from hackers if a draft bill (pdf) by the House Energy and Commerce Committee (HECC) becomes law. The law would make independent oversight of the electronic safety of motor vehicles a crime subjecting well intentioned security researchers to a $100,000 fine per instance. Today’s cars have 200 – 400 microcontrollers and microprocessors in them making the access of each an individual offense subject to fines that could add up to millions.The security flaws of the Jeep Grand Cherokee were exposed this summer by security researchers Charlie Miller and Chris Valasek who were able to shut down the vehicle during operation by cracking the Wi-Fi password. The risks of huge fines would stop researchers from exposing critical motor vehicle vulnerabilities but it would not stop hackers with malicious intentions from invading vehicle control systems.To read this article in full or to leave a comment, please click here

Getting Started with Packet Pushers Community Podcasting

We wrote this introductory guide to help those considering Packet Pushers community podcasting understand what is required. This is not a detailed list of everything you will need to know. Rather, this guide shares enough information to get you started. You'll still have to do a bit of Googling, research, and decision making of your own. We hope this helps. Happy podcasting!

A Look at the New WordPress Brute Force Amplification Attack

Recently, a new brute force attack method for WordPress instances was identified by Sucuri. This latest technique allows attackers to try a large number of WordPress username and password login combinations in a single HTTP request.

The vulnerability can easily be abused by a simple script to try a significant number of username and password combinations with a relatively small number of HTTP requests. The following diagram shows a 4-fold increase in login attempts to HTTP requests, but this can trivially be expanded to a thousand logins.

WordPress XML-RPC Brute Force Amplification Attack

This form of brute force attack is harder to detect, since you won’t necessarily see a flood of requests. Fortunately, all CloudFlare paid customers have the option to enable a Web Application Firewall ruleset to stop this new attack method.

What is XML-RPC?

To understand the vulnerability, it’s important to understand the basics of the XML remote procedure protocol (XML-RPC).

XML-RPC uses XML encoding over HTTP to provide a remote procedure call protocol. It’s commonly used to execute various functions in a WordPress instance for APIs and other automated tasks. Requests that modify, manipulate, or view data using XML-RPC require user credentials with sufficient permissions.

Here is an example that requests a list Continue reading

Before adding solid-state drives, right-size your infrastructure using workload profiling

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.

If you’re looking to add Solid-State Drives to your storage environment you want to avoid under-provisioning to ensure performance and scalability, but to meet cost goals and avoid unnecessary spending you need to avoid over-provisioning. Workload profiling can help you achieve the critical balance.

A recent survey of 115 Global 500 companies by GatePoint Research and sponsored by Load DynamiX showed that 65% of storage architects say they are doing some sort of pre-deployment testing before making their investment decision.  Alarmingly, only 36% understand their application workload I/O profiles and performance requirements. They don’t know what workload profiling is and how it can be used to accurately evaluate vendors against the actual applications that will be running over their particular storage infrastructure.

Germany will make telcos share customer data with the police

Even as the European Union attempts to tighten privacy laws, law-enforcement interests have won a battle in Germany: a new law forces communications service providers there to once again make data about their customers' communications available to police.On Friday morning, the German parliament approved a law requiring ISPs and mobile and fixed telecommunications operators to retain communications metadata for up to ten weeks.The country has had an on-again, off-again affair with telecommunications data retention, first introducing a law requiring it in 2008 to comply with a European Union directive.MORE ON NETWORK WORLD: 6 simple tricks for protecting your passwords The German Federal Constitutional Court overturned that law in March 2010 after finding it conflicted with Germany's privacy laws, prompting the European Commission to take the country to court in May 2012 to enforce the directive.To read this article in full or to leave a comment, please click here

AT&T to ‘lifelong customer:’ Shut up & talk to the lawyers

You don't need an MBA to know that in business, few things are more important than listening to your customers. So it's surprising that AT&T CEO Randall Stephenson, who earned an MBA from the University of Oklahoma, told a customer that AT&T isn't at all interested in his suggestions. Ever. In fact, if you send Stephenson an unsolicited suggestion, you'll get a similar response from his lawyers.
