I’m getting ready for a fun little project with a friend. Several years ago, while doing my undergrad, I got a copy of Chris Sander’s “Applied Network Security Monitoring.” I was going to do a book study group at school when it came out, but it turns out it was a required text for my Incident Response course.
Sadly, that class was a mess, and I don’t think we used the book in it at all. A different friend and I referenced the book to build a project for one of our other classes. We used it to build several honey pots, with what was supposed to be centralized logging. That, however, failed due to the Data Center we put the logging server in. The DC we picked for the log server didn’t allow logging to that DC for some reason. The other ones through the VPS provider would have worked fine. Just not that one. No clue why. We did complete the project with the honey pots but had to monitor each one instead of having central logs.
We live, we learn. A year ago, I had this post about my raspi-NAS failing. One of the things I said was I’d look into building a real RAID 1 based NAS on a Raspberry Pi.
Yeah, researching that subject while rebuilding my home network a few weeks ago, I found out that USB and RAID don’t work together like that. So, if I want a NAS with RAID, I’d have to do something else. Like a rack-mounted server running FreeNAS. Yes, I know it’s being rebranded TrueNAS Core.
I tried Open Media Vault (OMV) with my existing powered external hard drives. It didn’t like them. OVM could see the drives but wouldn’t let me do anything other than formatting them.
I’m sorry, I’m not interested in losing all my data. So I just set up the Raspberry Pi to run Samba again. It works fine.
I might try to rerun OVM someday when I have free time and free hardware to set it up, but I have a long list of things to do before then.
Shortly after rebuilding my Raspberry NAS last year, it stopped working again. The system wouldn’t boot right, even after changing the micro-SD card with a new build of Raspbian. A few weeks ago, I bought a new Pi 3 b and rebuilt the NAS again. When the system powered on, one of the USB drives wasn’t working. It looked like the file system was corrupt. During attempts to recover the USB drive, it stopped being readable. Both my Windows and Linux computers could see the USB drive, but not the file system, or the data. I re-formatted the disc drive, and it started working fine, it just had no data on it.
An industry mailing list I’m on recently had a conversation that started asking about Master Degrees but had some hiring managers chip in. They said a question they tend to ask is to have the candidate tell about their home lab.
I’ve been asked this question a few times in the past, and I’ve asked people this question in job interviews. I know it’s to find out what kind of passion the candidate has for the job, but I think it’s starting to become a bad question to ask.
I’ve made changes to the layout of my home lab. This is the current plan, because I can’t afford the Cisco switch I want right now. I also don’t think it’s worth getting a second line to the house, since I plan on moving by October.
The new design is to have my home network and the lab network mixed. I do have one more wireless router I could put in place to isolate the lab, but not going to for right now. If I need to limit things for something, I can always change. It’s also split between 2 floors, which is why there are 2 switches.
The Single Board Farm is 6 Raspberry Pi B, 4 Raspberry Pi B+, 2 Raspberry Pi 2, and once I can get them, Odroid C1 (probably 2).
Finally got time to pick up from where I left off last time. I’ve had a hard time getting to do lab work. Anyway. I connected my pfSense box to my AT&T U-verse Router Gateway, something I’ve been worried about, and it worked. I was worried because in the past, it would shut down the RG saying there was a network behind network, turn on DMZ Plus mode, and everything would be broken.
Issues were with the installer software. It took a few tries to figure out I needed to run it as admin, mostly because the screens are all in German (I think). I tried other software (the one I use for the Raspberry Pi stuff) didn’t work.
Booted off the console, used the installer (after I got the right image, can’t use the iso image), and installed it. Next up, getting it on a network to use the Web interface to configure the box. Or use SSH. Maybe just plug in the laptop and see what happens. That’s half the fun anyway, or so I think.
Got the first firewall for the lab. It is a PC Engine APU1D4D.Y.I Kit from Netgate. This hardware has been going out of stock constantly. I got the 30 gig flash drive from Amazon, for less. I should have taken pictures as I was building it, but was just excited to be building it.
easy open packaging
other than the heat spreader it went together really quickly
Online documentation available
No Instructions in the box
The heat spreaders didn’t like to stay on the chips
the heat sink move pulling the spreader off with it while putting the bottom on. Didn’t cause problems, but had to stop and reline up the head spreader to the chips (stuck to heat sink).
