Tor/VPN Router [How To Auto-Connect VPN After Tor Connected at Boot]

Dear Instructables Family,Hope you are well and healthy. My name is Enes and i am living in Istanbul. As you know in my country everything is being enforced by brute force to people. Tor, Wikipedia, Imgur, Pastebin, NordVPN, ProtonVPN, Privateinternetacces, PureVPN, etc. many website and service is blocked. There is no "privacy" in my country. For this reason i am looking for a "full privacy solution" for me and who is living same fate since years. I read many article and project but i couldn't believe they are "full privacy solution". Today i encountered with a "Raspberry Pi VPN server project" and i liked it. I have one (RPI 3B) and want to make a full privacy solution with VPN and Tor (with obfs4 bridges it is working but they are blocking everyday our bridges and we need to find another bridges every day). I created a Tor router with RPI and it is working good (little bit slow but i don't have any choice). But i want to add more security and privacy to this router. For example i have a VPN membership but i can not use it because it is heavily blocked. I want to do something but i couldn't find how can i make. Let me explain.My Onion AP is working for now good and when i connect as a client from a computer, i can access https://check.torproject.org website and everything is OK.My VPN membership supports TCP and UDP OpenVPN. It has TCP and UDP .ovpn files with a lots of country. I installed Open VPN on Raspberry and configured it for auto-connect at boot. It is working, when i reboot Raspberry, it connects automatically. But i have a problem.This VPN firm is heavily blocked and i can't use it. I tried ikev2, L2TP, Obfuscated Servers, Onion Servers, Double Servers and Standalone Servers of this VPN but there is no luck. Then i tried something. I connected Tor Router from computer and tried to connect this VPN firm. I could connect, it worked. Because i connected first Tor router and then VPN.My current schema is this:RPI ---> Internet comes from eth0 ---> Tor ----> Share Tor Connection by wlan0To Do:RPI ---> Internet comes from eth0 ---> First Connection Tor (I don't want to share Tor connection immediately because i need to connect VPN with Tor, if i share immediately by iptables, there is no Tor connection and i can't connect VPN) ---> Then connect VPN ---> Share Tor/VPN internet by wlan0I searched on forums, blogs and websites lots of. OpenVPN is using tun0 interface. I have three (3) questions. I am stucked here.1) How can RPI connect VPN with Tor without forward Tor connection? (Connect VPN with Tor and then share Tor/VPN. 2) When i achieved these steps how can i test Tor/VPN connection from a computer (client)? I mean how can i seperate them? 3) Should i add these commands to iptables-ipv4.nat script?-A POSTROUTING -o tun0 -j MASQUERADE -A FORWARD -i tun0 -o wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPT -A FORWARD -i wlan0 -o tun0 -j ACCEPTIf i achieve this i will be so happy and restful.Could you please help me about these issues?P.S: Sorry for my bad English.Thanks in advance.Best Regards, Enes

how do I connect my 3d printer to the internet?

Right now i have one computer that can control my printer via octoprint on a raspberry pi with this setup. i would like to be able to bridge my wifi network and lan network then port forward the internet connected router.so i can access the printer anywhere but i have no idea how to do that with my strange setup. the network switch is only there because i don't have a Ethernet cable long enough to reach the router. unfortunately wiring the raspberry pi to the internet connected router is out of the question because it is a few rooms over and would require running the cable through walls. also i would like to do this without buying a WiFi adapter for the raspberry pi or anything else that costs money. help would be greatly appreciated thanks a ton.      Harry

Hobby CNC router/engraver idea

I recently had to fix a friends (chinese) mini router.Long story short short: I realised that those things are only good for a small Dremel but not a real router.After looking up what is available in the tinker areas it seemed the only way out is the expensive way of using servo drives.Not really easy to handle either if you want some Arduino or Raspberry do the computing parts...So what would actually be required to make a cheap but still usable tabletop router that can handle 10mm playwood or work with (at least) Aluminium?In most if not all cases the tool will limit the movement speeds quite drastically.If neither makes any sense to force the rotating tool through the material, nor to make several high speed passes to get the results.Even when engraving stone or aluminium (dry) you can only do it so fast.The hobby market is full of Arduino or Raspberry based router projects but most, if not all use standard Nema motors for the positioning.As a lot came from the 3D printing area I guess it just made sense.And if you want to run servo drives or similar you won't control them with some cheap Arduino.Nema motors however suffer from the problem of limited torque at higher speeds.And using normal gearboxes only goes so far as the higher the reduction, the lower the resulting max speed will be.Means in the real world a Nema motor would struggle with any gearbox to get a reasonable speed to work with high loads.I think the way out could be to use external encoders for the positioning.Like on the early ink jet printers the slotted band attached to the printhead did.Or if you are old enough you still remember the mechanical mouse that stopped working once the code wheels were full of dust.The Idea came to me when servicing a geared motor for a 8-way valve.Just a cheap Mabuchi RS555 style motor and a planetary gear box.Together they produce a whopping 800nM of torque and literally no backlash at all on the output side.High resolution encoder wheels with sensor are available quite cheap as well.I did some very basic math on the accuracy side of things based on a table size of 1.2x1.2m.Using a chain drive we are looking at less than 1/2 mm using standard chains and below 1/10 of a mm using tight, precision chains.Going lead screw and heavy duty, high torque the accuracy is about the same as on a good 3D printer but the speed will be quite slow - I guesstimated around 3-4mm/s.A heavy duty belt drive system seems to be perfect as we can adjust the drive pulley size to match the gear ratio and speed requirements.Chains work fine as well here but usually mean a higher overall cost.The benefits are really high torque with more than reasonable speed is possible.The mechanics and electronics can be kept very simple.No high speed processor required, a simple 8-bit Arduino Mega will do fine.No expensive motor controllers, just a simple DC motor driver with PWM control.Extreme holding torque when an axis is not moving thanks to the gearbox.Code sensor can be driven by the belt or chain to get direct distance measurements.Downsides of the approach....The initial costs will be higher than standard Nema motor based solutions.To my knowledge there is no Open Source project for this kind of approach available (yet).With the heavy duty mechanics it won't be very portable, best to have it stationary mounted somewhere in the workshop.Quick reversing of the direction will require suitable DC motor drivers that can not only reverse the polarity but also provide the option for a break resistor to allow a fast stop of the motor without backfeeding generated electricity.Getting 3 dimensions would require a motorised table which can be a challenge if you need to support a loaf of weight and stay steady while a tool causes a lot of pushing in all sorts of directions.Probably a sissor lift system in all four corners would work best here.Happy tinkering! ;)And if the idea is already out and in use just forget about it LOL

How do I set up a mobile wifi router (LAN), and a wifi windows machine? Answered

We are a collective of dancers and bicyclists that organize huge bicycle rallies up and down the west coast. There are dozens of bicycle sound systems on these rides, and we seek to send an airplay audio signal to everyone's smartphone with wifi. The software of choice is Airfoil. http://rogueamoeba.com/airfoil/  For it to send audio, it needs to be installed on a windows or mac computer (not cell phone or tablet). Smart phones can then receive the audio signal. I need help designing a road worthy wifi router and windows machine to be the moving hub of this wifi broadcasting party. Extra points for durability, signal strength and thrift. Please be detailed, because I am only vaguely knowledgeable of wifi, and I'm not that bright. Please note that I am well versed with other options for sending an audio signal. I have reasons for being this specific. Without your help, I would acquire a used netbook with a solid state drive running windows (maybe about $200), grab a wifi router (I have a few older ones lying around) run it all on an inverter and give it a go. Because I am a mac guy, I don't know how to do anything, like how to set up a local area network.... (I usually jam in a cable from a high-speed modem).... we are not doing that on a bicycle, so I'm a bit fuzzy on that part. I am well versed with power supplies, and willing for the range to be less than ideal at first... (that can be improved later) I am just looking to get a trial of this system up and running. I am most appreciative of your help, and I plan on writing a full article on what I've learned, if successful~ Thanks!!! Tor PS, Photo not of me, but these people are obviously awesome, and will love what we are doing.

Help: First project - Bluetooth HUD/Router (i don't know what it would classify as)

OK Here's what i'm trying to make you guys. Essentially id like to make a device that will connect to a smart device via Bluetooth and also can connect and transmit to up to 5 Bluetooth speakers (of any brand). i know some Bluetooth speakers now have duo casting or whatever its called but i would like to go a step further. honestly i have no idea where to start, currently what im thinking is using some model of raspberry pi as the backbone of this unit. i would imagine id have to wire 5 bluetooth transmitters and one bluetooth receiver to the pi but i have no idea how i would program the pi or wire it up. as said before this will be my first project so i am rather new to this whole concept of diy but i love the idea of making my own gadgets. i want the pi to recieve bluetooth audio from a smart device and then redirect the audio to the 1-5 other bluetoooth speakers that could be connected to it. i also think it would be really cool to 3D print a body for the pi unit that can house a decent sized rechargeable lithium ion battery, that could be recharged via micro usb or maybe type C. Another cool feature i thought of was if i could wire 6 usb ports to the rechargable battery that could be used to charge 5 bluetooth speakers and you phone in one go. i also suppose id need to put some kind of screen on the pi unit and program some kind of user interface so i could make pairing to the bluetooth speakers and smart devices easier. all in all i guess what im going for is a power bank with the ability to redirect bluetooth audio from a smartphone to multiple bluetooth speakers. is there anyone out there that could maybe help and suggest how to make such a device? constructive critism is welcome as are any ideas for extra features. also maybe point me in the right direction as to where i could purchase the parts for this?Parts i know i'll need5 bluetooth transmitters1 bluetooth receiver6 usb ports1 micro or type C port1 rechargeable lithium ion battery (preferably at least 10000 mah or more, more is always better)

ISP's an their sneaky ways of limiting your internet to a crawl

With more and more restiction hitting internet users I though I write a bit about the methods used to make our life harder than necessary. First example: Heavy gamer... Some people love their Xbox or PC for only one reason, online gaming. Too bad when all of a sudden your ping rates go sky high or the chat has a lag making good conversations during the game impossible. Second example: Streaming media... People like to watch what they want and when they want. Online streaming is a good way to get the latest trailers, catch up with your favourite shows or just to kill some time. Too bad when you notice the connection takes forever and that you can only watch in low quality without running into buffer problems. Last but not least P2P.... Although used for mainly illegal stuff, P2P is still not dead. A lot of software and even collections of documents are shared by the use of various P2P networks. Torrents are the most common ones but it really does not matter once your ISP has hit you hard. So what have all these in common when we speak about ISP troubles you might wonder? Well, firstly they cause a lot of traffic and secondly a large number of connections at the same time. Why would my ISP limit me? 1. You are using your internet for illegal downloads. Although in many cases the ISP won't be able to tell what you are downloading, but they can clearly see the volume of the downloads and that a P2P system is used. Does not take a genius to realise several GB a week on a constant base can't be all legal. 2. Cheap ISP A lot of our providers rent their bandwidth from another provider. This way they can provide cheaper prices but have to make sure not go over the allowance as it would could dearly. A good way of preventing this is to limit speed during so called peak hours - basically whenever a lot of people are online. 3. Your area.... Let's say you are living in a densly populated area. There you often have a single exchange for all internet and phone users. Although the numbers of possible users can be increased by adding more hardware, the bottleneck is the feed to this exchange. As they are owned by a single provider and every other ISP has to pay for the use it becomes clear that this provider will have the best speeds and traffic allowances for the people connected. In return the other ISP(s) will be reduced in speed and sometimes even the type of connection possible, for example blocking all P2P traffic completely. How do I find out what is happening to me? This is indeed a hard one! No ISP will tell you "Yes, we limited you to xxxx and these services are not working on your connection: ...." Their fineprint states you have internet and Email, depending where you are maybe online TV services. But this is only true for standard ports and protocols used! So for your favorite online game it might be possible to download the latest update in the GB range within minutes but still encounter a massive lag during the play sessions. Similar story for low speeds. It is common practise to prioritise traffic to local speed testing servers. This means no matter what "problem" you might have all test will give positive results. So you might be able to get high speeds in your tests but watching a Youtube video can mean to first buffer the entire video before you can watch it. You ISP won't support any requests as long as common speed tests work fine for you. A sure way of testing is to download a Linux distribution from a remote server. How long does it take to download? Now do the same using a P2P download of the same distribution. Did it take much longer or did you have problems connecting to peers? If so you are limited by your ISP. Be aware that this might be true for only one type of P2P network, while others are uneffected. For games check your Ping times against ping times done manual against a known server, for example Google. If they are close all is good, if the game ping is much higher (often in the thausands compared to around 300ms max) you are sucked into limitations. Ok, I am fairly sure I am limited by my ISP, is there anything I can do? If you mainly use the internet for illegal downloads you might want to consider going the legal way. For all others, check below. Main reasons for limits put on your account or connection are congestion (nothing you can do about except trying the ISP that owns your phone network and to pay more - and of course the amount of connections you make. Let me give you an example: Downloading a huge file from a server usually needs a single connection on port80. Doing the same using P2P services requires a lot of simultanious connections to many servers/PC's around the world. Only with enough, fast connections your download will progress at good speeds. You ISP can see the number of connections and cut them at a limit or completely disable the protocol used for the download. The result is crawling speeds for the download and you only see a few peers available. Multiplayer games often use several ports for the traffic, game status, chat, graphic updates like location of other players and so on. So if you play in a world with 8 of your friends and fight against 200 online players all these infos has to get to your system. Having a few kids all enjoying different online sessions at the same time certainly does not help either. ;) Unless you are permanently limited there are a few options to make things better: 1. Limit yourself to the off-peak times for big downloads. 2. Try to avoid multiple game sessions and downloads from a single internet connection, e.g: let the kids play with one console at a time. 3. Change the ports used by your program, sometimes the standard ports are used by everyone else around, changing them gives the ISP the option to spread the load. 4. Last and best option: Limit the amount of allowed connections. For games this is not always possible but for other services it is. Imagine your P2P program using 300 download sources at the same time. Every one has the actual data and a lot of other informations to transmit while your system has to send the receiving info to every single one. On top of all that you have the informations needed to find new peers, coordinate the parts and so on. You can limit those in the settings of the program. So instead of allowing 500 or more connections at the same time go down to 100 or less. Instead of allowing 100 half open connections (used to negotiate the download for a new peer) go down to 20. And of course limiting your own upload and the connections used for it does help a lot. Myths and alternatives.... You might have heard the things like "protocol obfuscation", "port hoppers" and similar exist, same for the "Tor" network and maybe even the "usenet". The myth behind all of them is the claim that oyur ISP won't actually see what you do and what your download. On top of that you have so called "VPN' services. Although some of the services will help you to overcome certain limits it does not change the fact that you ISP still can see your up- download volume and the number of connections in use. And trust me, they are not dumb either, so they will know anyway that you mostly use the internet for illegal downloads. After all, what reasons could you have to use encrypted services or to direct your traffic over VPN networks? Of course being in China or similar countries is a different story due to gouvernment restictions on the internet. As long as you do direct download with only a hand full of connections you should be fine, for everything else it comes down to luck. Protocol obfuscation worked for a few months until ISP's fixed it. The usenet might be an alternative but not for everyone. Even the famous Tor network or dedicated VPN services won't help you once your ISP got you flagged. The will simply limit everything besides standard protocols and ports, so you can use you Email and surf the net, even download directly for a server but everything else might be crippled. As I said earlier there is no way for the user to truely check what limits he has or what ports and protocols might be affected - you ISP won't tell you either. Before you get trapped into a new contract because your ISP is no good turn off all P2P and gaming for a day or two. Try again at night times after a reset of your modem/router. Quite often you will see it works just fine for a while. If so you can limit yourself, use off-peak times and so on. Sometimes it also helps to simply limit the download speed itself. Of course the best alternative is not to use illegal downloads and to seek local content for game servers or online video.
