How do I troubleshoot network issues? I've got my Pi connected by Cat-5 to my router. It is running things such as Pi-Hole, PiVPN, SSH, FTP, VNC and Plex. If I try to access the websites for Pi-Hole or Plex, they timeout ("The server where this page is located isn't responding"). The same happens with SSH - "ssh: connect to host 192.168.1.100 port 223: Operation timed out". And FTP - "Connection timed out or server hung up. The server you are connecting to may be configured to limit the number of connections you are allowed to make." Bizarrely, I can still connect to the VPN just fine. If I'm on the Pi, and type in netstat -lptn, it shows plenty of ports that are listening. For example code:

I wonder if you might have some kind of routing problem that could be causing that. Network wise, it might not know how to get there if it's using multiple subnets. Can you get your pihole to reach google sourcing from your interfaces?

Check iptables (iptables -nL)? It reads to me like something shut down outside access.

xzzy posted:If you want lots of power in a small box, get a NUC or something. If you want to gently caress around with servos or cameras or any other goofy electronics project you can think up, get a pi. I'm curious if the latest round of NUCs if they use USB-C for power. At that point you could just plug an Arduino in to it for the IO pins.

Yeah my work laptop has USB-C PD and its fantastic. Getting ready to buy my first new personal laptop in years and it will have USB pd. My goal is to get one of the Lenovo Graphics docks that's also a port expander and just do one cable for everything. At this point everything i own is USB-C except my e reader so its just one cable for everything now. Having a USB-C rPi would be amazing.

lmao @ me For weeks I've been struggling to figure out why I can't get any readings from the Adafruit DHT22 temp/RH sensor. I was further confused that the power pins did not appear to be giving the right voltages, or any at all. Finally I realized that I had the breakout cable / cobbler thing plugged into the pi backwards, since there's no orientation guide on the pi itself. Beware, check your pins, it could happen to youuuuu

I’d like to set up an rPi for Pi-Hole. Is there a recommended power supply, case, and SD card to get so I can just set this up and forget about it? Should I just get the CanaKit starter kit from Amazon? This will be plugged into a UPS so power surges shouldn’t be an issue.

The kit is good because you don't have to worry about buying pi + case + psu + sd card all separately, but the flirc case is apparently best in class and affordable from amazon so it might be worth just buying the things separately. e: oh hmm the flirc case doesn't seem to be sold by amazon anymore :/ mewse fucked around with this message at 22:05 on Mar 21, 2018 |

 my raspberry pi indoor weather monitor is alive, it's aliiiive!It logs indoor temperature and RH using a DHT22 sensor It logs indoor CO2 and VOC concentrations using a CCS811 sensor - still in its burn-in period so no useful results from this one yet It also logs outdoor temp, windspeed, and pressure by grabbing the info from NOAA every 5 minutes. Finally, I also wrote a nice ascii plotting utility based on gnuplotlib's terminal mode, where you can specify which of those data to plot, or plot all of them, you can specify how many hours back from now to plot, or whether to plot a specific day in the past, and you can specify whether to remove outliers at a certain sensitivity (possibly useful for the CO2/VOC sensor?). Behold! Gaze upon my boiler's long-rear end heating cycle on a 28F day. pre:

Next step is buy a weather station and register with CWOP! That way you don't have to harvest NOAA's information but can be a part of it.

Or should i build my own with the pi I like my Ambient Weather WS0900, and they just started integration with the Saratoga Springs template. I made a quick mock site at http://keiths.crappyfiles.com/index.php to test it out, and it works very nicely. I had the one from Costco (can't remember the name), and it broke within a year and a half.

Adafruit alsp provides little writeups on how to wire each one and basic driver code to use it. I also found adafruit's pi breakout cobbler handy for breadboarding, but beware my earlier post about plugging it in backwards :/ I also bought but haven't wired up yet a temp / pressure combo sensor to later put either outside or elsewhere in the house, the uh bmp280. Hit me up if you end up doing it and want my logging code.

Traditional method is a cron job that periodically checks its public IP and updates a dns server somewhere. dyndns was how you did it back in the day, not sure if they're still around/reputable. I do it with my digitalocean vps because they have a really cool dns API and I host my personal stuff there already.

unpacked robinhood posted:Baby question here: how do keep up to date with the public IP of a distant Pi ? Set up a dynamic DNS service and install the daemon/tool to automatically update the IP address? I use no-ip for my sites. One site has the update service running on a QNAP NAS, and two have it running on Ubiquiti routers, so I haven’t messed with getting the service to run on Linux though.

couple questions: 1) once i get some trackers set up for indoor temps, co2, pulling external info, etc, would i be able to also set up a simple local website on the pi to display the info? I'm thinking like, 30 days worth of info where i can browse to weatherstation.local or something and check stuff out. 2) Is there such a thing as a solderless GPIO header for the pi zero? I've got a W that I'd like to set up with some sensors but also don't have a soldering iron and don't have any projects where I'd need one coming up.

I won't answer your actual question but I will tell you that if you plan to do any electronics work, even at an amateur level, you should really just get a soldering iron

Just like having an electric saw (table or miter saw) does not make one a carpenter, having a proper soldering iron does not make one an electrician/tinkerer either. I know, i speak from experience in both cases.

A soldering iron doesn't make you an electrician, but having some tools that you only sort of know how to operate and using them to break things more often than you fix them (at least at the beginning) is basically the definition of tinkering

GobiasIndustries posted:couple questions: 1) idk much about that but for my own project I borrowed a little info from this guide, which goes on to set up an SQL database and stuff, which I didn't do those parts, but you might get some helpful info from it. 2) First of all, having a soldering iron owns, as others have said. Apart from my own little projects, I've repaired so many friends' broken headphone cables and stuff. But, Adafruit makes a "pi cobbler breakout" that runs a ribbon cable to a breadboard and has all the pins labeled. I found it really useful for prototyping, and in fact my sensor suite is still running from the breadboard. I plan to stick it through perf board and solder it soon to make it more permanent but  If you haven't used a breadboard before, it's a board with a bunch of rows of little plugs that you can simply plug an end of solid-core wire into, and all the plugs in each row are connected to each other. The other option is get jumper wires with little female tips that are similar kinds of plugs as what you plug into in a breadboard. Those female tips could plug right onto the GPIO pins right on the pi itself. Whether the other end is male or female is up to you but they sell both types (search for "female to female jumper wires" for example). e: oh poo poo I just noticed you're talking about the pi zero and I googled it and it looks like it just has holes for header pins... welp ignore my advice and get a soldering iron.
