Collection of useful, relevant or just fun places on the Internets for 5th February 2014 and a bit commentary about what I’ve found interesting about them:
I don’t usually import AutoCAD files into Cisco Prime. But when I do, I do it in style « @WirelessStew – Cisco Prime and AutoCAD ? Who knew.
Do you prefer to import AutoCAD files into Prime Infrastructure over a JPG or PNG perhaps? Sure we all do. Here are some things you need to know about Prime and CAD files.
Stumbling around the Fortinet CLI… | Just another day at the office… – One of the oldest network design mistakes in the book. Database connections through the firewalls timing out –
My most successful strategy has been to take up residence in Wireshark Land, where the packets don’t lie and blame-storming takes a back burner. Recently, for example, I took captures on two Linux servers, one a web server in the DMZ, and one a database server on the internal network. The captures showed that the web server could initially reach the database server, but that communications broke down after a few minutes. The database server clearly didn’t get the last of the web server’s packets.
Once learned, never forgotten!
How Cisco’s almost-open SDN outruns VMware – Solarwinds licenses their software on a per node/per port/usage basis for most of their products. So I find more than a little ironic when the Solarwinds Patrick Hubbard start saying that customers don’t like unit pricing. Double standard ?
ACI is also likely to win with the network team when it comes to licensing. With NSX, VMware wants to extend its per-VM licensing model to the network via VM awareness. But network engineers have always paid for boxes, ports and bandwidth. To us, per-VM pricing is repulsive. Service delivery is ultimately about pipes, not an ever-changing virtual machine inventory we have to get from the systems team. ACI keeps licensing around infrastructure features and capacity rather than VM endpoint count.
10 Things We Forgot to Monitor – Bit.ly talks about their experiences of running an application at scale. Food for thought for network engineers – insight into applications:
There is always a set of standard metrics that are universally monitored (Disk Usage, Memory Usage, Load, Pings, etc). Beyond that, there are a lot of lessons that we’ve learned from operating our production systems that have helped shape the breadth of monitoring that we perform at bitly.
App Proves Adage: Just Because I’m Paranoid Doesn’t Mean They’re Not Watching Me – IEEE Spectrum – More proof that Oracle is not safe for use and that you should taking extreme and expensive mesaures to protect your business from long standing Oracle vulnerabilities that are well known to attackers.
Bad: Two vulnerabilities in Oracle’s older database packages allow hackers to access a remote server, view the server’s file system, and dump files—all without a password. Worse: More than two years after security researcher Dana Taylor reported the flaws, Oracle has yet to release a patch for one of them, and, according to Taylor, the patch belatedly created for the other didn’t actually fix the vulnerability. Worst—for Oracle, anyway—Taylor kept detailed notes on her interactions with the company.
Markdown Tables generator – TablesGenerator.com – What it says. Lots of people struggle when starting to use tables in MultiMarkdown so this can be a great help.
Pedro Lobo – MailMate Bundle for TaskPaper – Takpaper and Mailmate integration. Yes, those are little tears of joy in my eyes.
Command Bundles, one of it’s many powerful and still undocumented features, allow you to send emails to a barrage of apps such as OmniFocus, Things, 2Do, Evernote, Fantastical and BusyCal to name just a few. I decided to add one more to that ever growing list… TaskPaper.
