2003 Mitsubishi Magna TS Ignition Issues

TL;DR: If you’re having intermittent issues starting your Magna check out the details at this link: https://martybugs.net/articles/magna-stall.cgi Just a quick-ish one today. I’ve been bashing my head against an issue we’ve been having with our 2003 Mitsubishi Magna for several months, initally when you try to start it. It will fire up for about a second then the ECU kills the engine, sometimes after 4-5 attempts you can get it to start but sometimes it just outright refused. We’ve had the RACV out a couple of times, each time they’ve diagnosed no spark and we’ve towed it back home....

FreeIPA on Ubuntu with a Side of Unbound

TL;DR: Getting FreeIPA 4.7 fully functional is a pain in the arse (and not just on Debian/Ubuntu), I’d STRONGLY recommend you get a distro that has 4.8 packaged as that gets rid of a lot of the python 2 nastiness. Because managing users on 20+ individual VMs manually was getting a bit beyond the pale I decided it was about time to delve into the wonderful world of Linux directory servers, enter FreeIPA. Now a sane person would probably have built their FreeIPA directory servers on Fedora, CentOS or RHEL because, let’s face it, if Red Hat is the primary...

Dedicated VMKernel Storage Adapters in ESXi

This is a bit of a corrolary to the previous couple of posts regarding the self-hosted filer on ESXi, you may want to (and probably ought to) setup a dedicated vmkernel adapter for your iSCSI storage, it’s a bit of a pain in the arse so I figured I’d write it up… First thing, you’ll need a new vswitch (Networking->Virtual Switches->Add standard virtual switch); New "Storage" vSwitch creation If you’re not planning to expose the iSCSI storage...

Enabling ESXi Autostart for Self-Hosted iSCSI/ZFS Filer

Obviously if your filer is a VM on your ESXi box your datastore won’t be available until that box is fully booted, this is rather irritating as generally one wants at least some of the VMs on a given host (aside from the filer) to boot when the host boots, fortunately this is not too hard to fix. Important note (trap for young players, and something I derped on for a couple of days the first time round…) there’s a global setting to enable autostart, Manage->System->Autostart->Edit Settings->Enabled->Yes, probably also want to set “Stop Action” to “Shutdown” and enable “Wait for...

Self-Hosted iSCSI/ZFS Filer on ESXi

Intro As a follow on to “Creating a Datastore on your ESXi USB Boot Drive”, I’m now going to go through the process of setting up a “self-hosted” filer to support the actual VMs, I’m mainly doing this to save me having to either remember what I did or figure it out again next time ;) This is for my home lab whereas the “USB Boot Drive” process was developed for another box, in this case I’m fortunate enough to have spare controllers and bays in my home box (that SC836 I picked up on eBay), so I’m...

So You Want a SuperMicro SC836 Chassis

TL;DR: if you want a SuperMicro SC836 Chassis look on eBay for the Dell CT-040 instead, continue reading for some caveats around that. I’ve been in the market for a SuperMicro SC836 chassis for a while now, seemed the logical upgrade path from my existing NAS solution which uses a full-tower case with two four-in-three hotswap adapters in it (units which contain 4x3.5” sleds and fit in the space of 3x5.25” bays, though some… pursuasion was required with respect to the sheet metal inside the case). The SC836 is a nice 3RU rack mount chassis with 16x3.5” hotswap bays on...

Creating a Datastore on your ESXi USB Boot Drive

A quick note on this, I suspect that this would have been less of a pain if we’d have opted for using the internal micro-SD slot in the server rather than stuffing a 16GB USB3.0 stick into one of the internal USB ports, so you might want to explore that option before going down this path, I chose the USB stick because theoretically at least a decent USB3.0 stick should be faster than an equivalent micro-SD. Intro When you install ESXi onto a USB stick it doesn’t create a “datastore” partition like it does when you install to a...

Upgrading Storage in the Kobo Touch

It’s been far too long since I’ve posted, I know, but shrug that’s life. Yesterday I noticed that the screen on my Kobo Touch eReader (doesn’t get much use, so I only occasionally see it) was displaying garbage. I figured it had crashed or something so (forgetting the reset button on the back) I cracked it open to disconnect and re-connect the battery, when I did that I found this. Note that the battery connector wasn’t broken from factory, just seems to be VERY fragile, as it broke as soon as I tried to unplug it, fortunately there’s enough of...

2016/2017 Ruxcon HHV code is finally on Github

So I finally got around to sticking the code from the last two years’ Ruxcon Hardware Hacking Villages up on github, you can find it here; 2016: https://github.com/darkglade/ruxconhhv2016 2017: https://github.com/darkglade/ruxconhhv2017 If I’m really organised I’ll stick the code up prior to the con next time :)

Metasploitable3 Community CTF - Walkthrough(ish)

This isn’t intended as a “full” walkthrough, I’m basically just going to outline my approach and perhaps mention a few alternatives. A quick note; this is the first time I’ve participated to any major degree in a CTF contest (Though I have tested and designed a number of levels for the Ruxcon CTF over the past couple of years), I’ve poked at a few in the past but I seem to quickly lose interest. I think the fact that this one was over a defined time period and that the #ctf-support channel was there on slack really helped to...
