From this setup for OpenVPN Server on Ubuntu 16.04..
We need to unbolt some of the security features of the server config for Mikrotik compatibility… took some tinkering to solve this
Following this guide.
NOTE 1: In the part where they edit
I edited the server directive to read:
server 192.168.155.0 255.255.255.0
then my UFW rules are
# START OPENVPN RULES Continue reading “OpenVPN Server on Ubuntu 16.04”
# NAT table rules
:POSTROUTING ACCEPT [0:0]
# Allow traffic from OpenVPN client to ens3 (change to the interface you discovered!)
-A POSTROUTING -s 192.168.155.0/24 -o ens3 -j MASQUERADE
# END OPENVPN RULES
So the banana plugs on the back of my sub failed/the plastic back plate melted when I used the sub as a wind break. I decided to re-do the connection using really good Neutrik Speakon connectors.
It’s been too long since I put some time into this project, so I’m going to outline goals broadly and then narrow into smaller components.
Steps 1-3 represent the bulk of the electronic challenges. Step 4 is the physical challenge Continue reading “SAP – refocusing”
In Ubuntu 16.04 DNSCrypt can be installed from apt-get:
sudo apt-get install dnscrypt-proxy
Assuming a wireless interface is setup and working on the router, we can add a virtual interface, give it it’s own subnet, and isolate that subnet from the existing LAN. Note: these routers don’t seem to like multi-tasking/wi-fi too much Continue reading “isolated wifi using a Mikrotik wireless router”
The main challenge installing guy wires onto a tiled roof was how to make anchor points. I went to a local antenna supplier and they told me the usual method is with these long self tapping o-ring bolts. So that’s what I did, it was much easier than I expected.
I used a diamond hole saw from eBay to make 2 holes in the roof tiles, and made use of an existing satellite dish mast for the final mounting point. I used threaded rod to attach a tapped o ring (or whatever you call it) to the satellite mast. Using a wet finger I was able to mold silicon around the anchor bolts in the roof tiles.
From my understanding it’s better to be earthed than not… I tried running conduit through this cement path using only an angle grinder and a chisel. This would have taken waay too long. Ended up buying a jack-hammer from gumtree (cheaper than renting). The second earth wire is from a UBNT Ethernet protector in the roof-space. This goes to a separate earth rod a small distance from the mast earth rod.

Lots of welding, mucking around and measuring several times. All the tolerances were pleasantly as expected. Continue reading “Beaumast Part 1”
I moved the project to some acrylic in what is possibly the final stage for the project.While I thought the software reset for the Ethernet chip would suffice for connection problems, it appears this isn’t the case. I’ll try reprogramming the chip with an interrupt reboot for the main program loop, currently the device isn’t sending info to ThingSpeak.
Once the code is running smoothly (for at least a week) I’ll add email notifications. In the future I won’t use this Ethernet chip, there is a similarly priced chip I have which is much more capable.
