Worth Reading: Broadband Speed Tests

Everyone is familiar with broadband ‘speed test’ applications. When you have an ISP service quality problem, it is common to grab one of these tools to see if you are getting the service you feel you are entitled to get. Whenever you upgrade your broadband, the first thing you might do is to run a speed test. Then you can show off to your mates how superior your blazing fast service is compared to their pitiful product. -via Circle ID

Apple’s SAP deal means more iOS enterprise apps

In an effort to expand its presence in the enterprise market, Apple this week announced another major partnership with a business-software giant.  In a wide-ranging deal with SAP that's set to begin later this year, Apple will work alongside one the stalwarts of enterprise to develop more native iOS apps, as well as an SDK for SAP's HANA cloud platform. The SDK is designed to let SAP's more than 2.5 million developers build native iOS apps that can tap into SAP systems and access data in real time. The agreement also includes a plan to establish a new "SAP Academy for iOS," a place where SAP customers and partners can meet in person to design apps for iPhones and iPads and received related training. Apple and SAP engineers will work together to build apps, and the concept is similar to Apple's IBM MobileFirst for iOS initiative.To read this article in full or to leave a comment, please click here

Cloud coding pitfalls: Tips for avoiding big, bad bugs

According to this ACM article, the seven coding constructs that have been the most frequent source of bugs are function calls, assignments, conditions, pointers, uses of NULL, variable declarations, function declarations, and return statements. There are dozens of other conference presentations, books, and taxonomies that provide statistically valid guidance — or at least opinions — on coding practices to avoid.But so far, I haven’t found anything like that for coding in the cloud.And make no mistake about it, the distributed, multi-language environment inherent in the cloud presents some real coding challenges. But before we nerd out entirely, let’s do a bit of bug triage. There are three interesting categories of bugs:To read this article in full or to leave a comment, please click here

sFlow to IPFIX/NetFlow

RESTflow explains how the sFlow architecture shifts the flow cache from devices to external software and describes how the sFlow-RT REST API can be used to program and query flow caches. Exporting events using syslog describes how flow records can be exported using the syslog protocol to Security Information and Event Management (SIEM) tools such as Logstash and and Splunk. This article demonstrates how sFlow-RT can be used to define and export the flows using the IP Flow Information eXport (IPFIX) protocol (the IETF standard based on NetFlow version 9).

For example, the following command defines a cache that will maintain flow records for TCP flows on the network, capturing IP source and destination addresses, source and destination port numbers and the bytes transferred and sending flow records to address 10.0.0.162:
curl -H "Content-Type:application/json" -X PUT --data  '{"keys":"ipsource,ipdestination,tcpsourceport,tcpdestinationport", 
"value":"bytes", "ipfixCollectors":["10.0.0.162"]}' 
http://localhost:8008/flow/tcp/json
Running Wireshark's tshark command line utility on 10.0.0.162 verifies that flows are being received: 
# tshark -i eth0 -V udp port 4739
Running as user "root" and group "root". This could be dangerous.

IDG Contributor Network: Emergency call location for mobile UC: slow progress on E911 improvements

Making enterprise voice-over-Wi-Fi systems comply with emergency call regulations requires shoehorning new techniques into a very old architecture. It also exposes some unfinished technology and fragmented implementation models. We can do it, but no one is happy with the contortions.There’s a large population of enterprise unified communications (UC) systems from Microsoft, Cisco, Avaya, Shoretel and others using Wi-Fi endpoints, whether dedicated Wi-Fi phones or client apps on smartphones. When it comes to emergency call functionality, we should expect these to work at least as well as landlines, PBX extensions and cell phones.One of the most important emergency call (E911) functions is locating the caller. To make emergency call location work, we first need to find the location, then send the call, with caller location attached, to the correct emergency answering center in a form it can understand. Both of those steps present problems.To read this article in full or to leave a comment, please click here

Qualcomm flaw puts millions of Android devices at risk

A vulnerability in an Android component shipped with phones that use Qualcomm chips puts users' text messages and call history at risk of theft.The flaw was found by security researchers from FireEye and was patched by Qualcomm in March. However, because the vulnerability was introduced five years ago, many affected devices are unlikely to ever receive the fix because they're no longer supported by their manufacturers.The vulnerability, which is tracked as CVE-2016-2060, is located on an Android component called "netd" that Qualcomm modified in order to provide additional tethering capabilities. Malicious applications could exploit the flaw in order to execute commands as the "radio" system user, which has special privileges.To read this article in full or to leave a comment, please click here
