How to set up and optimize an Asus RT-AC66U

Dave Farquhar — Mon, 05 Dec 2016 12:00:03 +0000

Consumer routers drive security professionals like me crazy. I’m happy to say I finally found a router that doesn’t drive me nuts. I want you to buy an Asus RT-AC66U. I’m going to tell you why, and I’m going to

Moving SSH off port 22 doesn’t do much for security

Dave Farquhar — Thu, 12 May 2016 11:00:55 +0000

A week or two ago, a stranger approached me with some advice about securing routers: move SSH off port 22. Since arguing with strangers is what the Internet was apparently invented for, I’ll argue against the benefits of moving SSH off

Why MAC address filtering doesn’t help security

Dave Farquhar — Thu, 07 Jan 2016 12:00:33 +0000

The other question that came out of my recommended DD-WRT settings was why not filter MAC addresses. I hate to be flip, but MAC address filtering doesn’t help, so why bother? The reason is because your MAC addresses are broadcast as

Bash is worse than heartbleed! Oh noes!

A really bad remote code execution bug surfaced yesterday, in Bash–the GNU replacement for the Unix shell. If you have a webserver running, or possibly just SSH, it can be used to execute arbitrary code. It affects anything Unixy–Linux, BSD, Mac

The Logitech F310 on Retropie

Dave Farquhar — Thu, 17 Jul 2014 11:00:27 +0000

I went looking for a reliable, modern controller to use on my Retropie setup. I eventually settled on a Logitech F310, betting the Logitech F310 on Retropie would make a nice combination based on my experience with other Logitech peripherals in regards to

Setting up Retropie on the Raspberry Pi

Dave Farquhar — Tue, 15 Jul 2014 11:00:27 +0000

I bought a Raspberry Pi over the weekend intending to turn it into a retro gaming system. I’d rather not have a mess of systems and cartridges out for my kids to tear up and to constantly have to switch

The ghost in the network

Dave Farquhar — Tue, 17 Dec 2013 11:00:19 +0000

My logging system died rather abruptly one week. It started with the Active Directory account some of our servers use locking. I got the account unlocked–someone else has those rights–and the system came back to life for a while, but

Here’s a nice Linux tool: checkrestart

Dave Farquhar — Tue, 12 Mar 2013 10:00:52 +0000

Tom Gatermann told me about a nice tool for Debian (and presumably Ubuntu) called checkrestart. Sometimes, even though you did an apt-get update and apt-get upgrade to bring your system up to date, you can still be running the out-of-date

Unix-to-Windows copies with PSCP

Dave Farquhar — Tue, 13 Mar 2012 00:47:01 +0000

I’ve been moving files between Linux servers, and to and from Windows boxes, as part of my server migration. I started to write about how I’ve been doing it, but it seemed oddly familiar. Yep, I’ve written about SCP and

Upgrade update

Dave Farquhar — Tue, 14 Feb 2012 05:04:38 +0000

My new fire-breathing dragon of a server is sitting idle at the moment. I would have liked to have had it up and running today, but now I’m starting to realize why it took me so long to migrate off
