  Router requirements?
Posted by: dumore - 06-16-2018, 11:54 PM - Forum: Skywire - Replies (3)

Greetings,

For the DIY miners, are there any specific requirements we should be looking at for the router, or does it just have to be running on OpenWRT?

I ask because there are lots of routers in the supported list: http://openwrt.org/toh/start

Yet I keep seeing certain ones that are popular in the diy builds, for example the TP-Link Archer C7.  Is there something in particular that makes that one desirable enough that people are choosing it for this project?  Is there a specific package that needs to be installed in the OpenWRT linux distro for skywire or does it just need to have your basic OpenWRT firmware, with ports configured?

I think I have an Archer C5 laying around somewhere that I plan to try out, but from what I understand we aren't using the radios on the router anyway, so why wouldn't someone choosing one to buy go with, say, the C5 in the first place -- I believe it costs less than the C7 because the radios are lesser.. and if you continue on down that path, there are some on the list that seem quite capable but don't support 802.11ac radio or 5ghz, so they often go for less now than both the C5 and C7.

Granted most these price differences are relatively minor anyway, but having trouble figuring out why people are choosing certain routers.

Thanks!

  [Tut] How to be „Better Safe Than Sorry“ when becoming an Exit Node (VPS/VPN Setup)
Posted by: Clownstick - 06-12-2018, 12:07 AM - Forum: Skywire - Replies (8)

Once I heard about Skycoin, I was instantly hooked. I wanted to participate, but I was worried about becoming an „Exit Node“. Where I live (Germany/EU), local laws make me personally liable for everything illegal that is done by „me“ (my IP), so that was a big turn-off. Since I was using a Russian VPS hoster for VPN tunelling sporadically for the last couple of years, I knew what to do: I wanted to route all Skywire traffic through my VPN so that my actual personal IP wouldn’t show up anywhere. Better safe than sorry, right?
I noticed several other people having the same concerns over and over again, so I thought I’d make a „quick“ tutorial on how to setup the VPN. Keep in mind though, that in this tutorial we will create our own VPN service on a VPS (Virtual Private Server) instead of using a dedicated VPN hoster. It’s a hell of a lot more work but there are several upsides: It’s dirt cheap, IP’s aren’t blacklisted, it’s stable and you can use your VPS for anything you want. Plus, you can use your newly created VPN for an unlimited amount of devices as well.

For the sake of the Tutorial, I will use the combination that I’ve been using for the last several years: A VPS with the Russian Hoster „VEESP“ (former „Vstoike“) combined with SoftetherVPN Server.
You can switch out the hoster for pretty much anyone else (just make sure they DO NOT work closely with EU/American Authorities when it comes to DMCA/Copyright stuff or worse!), but you can’t use any other VPN Software if you want to follow this Tutorial




Requirements:
-         Already pre-configured and running Skyminer Setup (Personally, I have followed this guide here https://skywug.net/forum/Thread-Raspberr...TNET-READY)
-         Router that is capable of running a VPN
-         6+ Bucks via Paypal or Bitcoin for the VPS Hoster

Note: I have no idea if this setup works with the "official" Skyminer since I only have a DIY Raspberry Pi one. So take this Tut with a grain of salt if you're on the official Miner!
 
With that being said, let’s get started!



1. Setting up the VPS

At first, you need to buy the VPS. Go visit VEESP or the Hoster of your choice. Select the option that you want. I can recommend the „Linux HDD VPS – HDD 1“ because it has unlimited Traffic and 50GB of storage in case you want to run and/or download several things on it. It’s 6€ Monthly, you get 10/20/30 percent off if you pay Quarterly, Semi-Annually or Annually. Choose the option you’re comfortable with. If you decide to go with VEESP, I'd appreciate it if you'd use my Referral since I get a small commission (it doesn't cost you any extra). Ref-Link  Non-Ref-Link
Regarding the Hostname: Just choose any name, it’s not important. Go with „anydomainname1.com“ or something. After you’ve paid the Invoice, the VPS is pretty much instantly available and you can get right to it. 
Go to „Client Area“, then select your VPS. Open Putty (or any other SSH Terminal) and log into your VPS with your login credentials. At first, make an update.

Code:
apt-get update && apt-get upgrade -y

This could take a while.


Then either stay logged in as "root" or just add another user and grant Sudo privileges (replace "Bob" with your actual Username or just copy+paste this one):
Code:
adduser Bob
adduser Bob sudo
Logout, then login as "Bob".




2. Setting up the VPN Server on our VPS

 install Lynx:
Code:
sudo apt-get install lynx -y

Use Lynx to download Softether VPNserver
Code:
lynx http://www.softether-download.com/files/softether/
and chose the appropriate Version (Latest RTM -> Linux -> Softether VPN Server -> 64bit Intel x64 or AMD64). Press "D" and then Enter to "Save to Disk". I went with the Version
softether-vpnserver-v4.25-9656-rtm-2018.01.15-linux-x64-64bit.tar.gz. After saving, you can just press "Q" to quit.


Now unpack the file:
Code:
tar xzvf softether-vpnserver-v4.25-9656-rtm-2018.01.15-linux-x64-64bit.tar.gz

Now make sure the appropriate tools are installed:
Code:
sudo apt-get install build-essential -y



Now switch to the "vpnserver" directory and install it (press "yes" / "1" for all):
Code:
cd vpnserver
sudo make

Move the vpnserver directory and change file permissions:
Code:
cd ..
mv vpnserver /usr/local
cd /usr/local/vpnserver/

sudo chmod 600 *
sudo chmod 700 vpnserver
sudo chmod 700 vpncmd

The next step is to make Vpnserver run at startup (optional, but strongly advised!)
Code:
sudo nano /etc/init.d/vpnserver

paste the following into the file:
Code:
#!/bin/sh
# chkconfig: 2345 99 01
# description: SoftEther VPN Server
DAEMON=/usr/local/vpnserver/vpnserver
LOCK=/var/lock/subsys/vpnserver
test -x $DAEMON || exit 0
case "$1" in
start)
$DAEMON start
touch $LOCK
;;
stop)
$DAEMON stop
rm $LOCK
;;
restart)
$DAEMON stop
sleep 3
$DAEMON start
;;
*)
echo "Usage: $0 {start|stop|restart}"
exit 1
esac
exit 0
Press Ctrl+X to exit, Y to save and then Enter.


Make a new directory (if not existing already)
Code:
mkdir /var/lock/subsys

and change the permissions for the vpnserver and the startup script:
Code:
chmod 755 /etc/init.d/vpnserver && /etc/init.d/vpnserver start

Now you've successfully installed Vpnserver. Check if everything is working:
Code:
cd /usr/local/vpnserver
./vpncmd
press 3 (VPN Tools) and then type "check".
If everything is working fine, you should get a couple of "PASS" messages. Exit the VPN Tools by writing "exit".


Run "./vpncmd" again and press "1". The following step is not "official" but any other way gave me an error: 
Regarding the "Hostname of IP Address of Destination"... type in YOURSERVERIP:5555 and press Enter ("official" guides tell you to leave everything blank but it didn't work for me. Only typing in the IP and Port 5555 worked!). Leave the next field Blank and press Enter.
Then, configure your (VPN)Server Password:
Code:
ServerPasswordSet

Idea How the next step is done comes down to personal preference. You can do it my way or follow strictly Terminal-based guides. Personally, I find the Windows Manager WAY more easy and intuitive than the SSH-Terminal-one.

After setting up my Server Password, I log out of Putty and do the rest via the Program "Softether VPN Server Manager for Windows" (Link Here).
Go to "New Setting" and type in YOUR VPS IP  and YOUR VPNSERVER PASSWORD and then "connect".
You don't necessarily need to create a Virtual Hub but you can create as many Hubs and Users as you want. For the sake of the Tutorial, we'll go with the Default one.
Setup your "DEFAULT" Virtual Hub with a click on "Manage Virtual Hub". VERY IMPORTANT: Click on "Virtual Hub Properties" and check the Box that says "No Enumerate to Anonymous Users"! 

Also, make sure you enable Virtual Nat and Virtual DHCP-Server. Visit the Virtual NAT Settings. Click on "Secure Nat Configuration". Very Important: Write down the "Default Gateway Address" (i.e. 192.168.30.1) on the right bottom side. You'll need it later.

Now create at least one User via "Manage Users" -> "new". Fill out the "User Name", leave everything on the left side blank. On the right side, just configure the Password for your User.
In the Main Menu of your DEFAULT Hub, activate IPsec and LT2P.

That's it! Your VPN is now ready to rock n roll!



3. Configuring your Subnet and your VPN Tunnel.

Now it gets a little more tricky (because every router and home setup is different) and I'll try and do my best to explain everything.

Let's assume you have the follwing Setup right now:
Your ISP Router: 192.168.2.100
Your Skyminer-Router: 192.168.2.160
Your Skyminer IP's: 192.168.2.161, 192.168.2.162, .......163, ........164 etc.

What I wanted to do is create a completely seperate Subnet WITHOUT any Port Forwarding rules. That means we have to create another Subnet (i.e. 192.168.0.1 ++). Since I can only connect to one Subnet at a time with one PC (without forwarding), I connect to the Skyminer-Router only via a different Machine (in my Case: Macbook via WiFi). So make sure you don't lock yourself out of any of your devices!


First, we need to change the IP-, Router-, and Gateway-Setting for the Skyminer Nodes via logging into each one and typing:
Code:
sudo nano /etc/dhcpcd.conf

Assuming you had the above setup with a .2.xxx Subnet, you'll need to change it to something like this (put in your respective desired IP's of course!):

Code:
interface eth0
static ip_address=192.168.0.100 #THIS IS YOUR SKYMINERS IP
static routers=192.168.0.1   #THIS IS YOUR SKYMINER-ROUTERS IP
static domain_name_servers=192.168.30.1 #THIS IS THE DNS OF YOUR VPN's VIRTUAL NAT (which you wrote down earlier)
Close Nano with Ctrl.+X, then Y, then Enter. Then reboot the Node with "sudo reboot".

Configure all existing Nodes like the above until you're done (with a different static IP for each node, of course). Note: They will not be available/online until you've configured your Skyminer-Router as well, so make sure you finish the setup completely until they're back up again!
When you're done configuring your Nodes, edit the static IP of your Skyminer-Router accordingly (in this case: 192.168.0.1). Make sure you have physical (LAN) and/or Wifi access to your Skyminer-Router! Because after you've changed the IP, you'll get kicked out (different subnet, from XXX.XXX.2.XXX to XXX.XXX.0.XXX) and need to reconnect!

After you've successfully reconnected to your Skyminer-Router you should be able to connect to your Skyminer-Nodes. You should NOT be able to access them from anywhere outside of this subnet (your "regular" home network) and vice versa. 

Now that your freshly created Subnet is working like a charm internally, you need to configure your Skyminer-Router to connect to the Internet Via your VPN-Tunnel. Unfortunately, I can't explain this step in detail because every Router is different but I'll try. I'll post my personal setup, only edited to match the IP's for this Tutorial

Connection Type: L2TP
Username: YOUR VPN USERNAME (The User you created for the DEFAULT Hub)
Password: YOUR VPN USER PASSWORD (The password for said User)

Addressing Type: Dynamic IP (it's only the IP that's given to our Router from our VPS, NOT our Internal IP!)

Server IP Address: YOUR VPS SERVER'S IP
Subnet: 255.255.255.0
Gateway: 192.168.2.100 (This is your ISP's Router)
DNS Server: 192.168.2.100 (This is your ISP's Router)

Internet IP Address: 192.168.30.10 (this is the IP that the DHCP on our VPS has given us, you don't need to change this)
Internet DNS: 192.168.30.1 (This is the "DNS-Server" from our VPS which you've written down earlier)



And that is it, folks. You can test your external IP when if you visit a site like "whatismyip.com" (when your PC/Mac is connected to your Skyminer-Router) and you'll see if it's working correctly. The Website should output that you're connecting from Russia (or wherever your VPS sits).
With this setup, everything in your "regular" home network is running just as before and has your residential IP (which is good because everyday services don't like it if you login with IPs from another country/continent!), and everything behind your Skyminer-Router will get tunneled through the VPN. Magnificent!


I wrote this Tutorial mostly at the top of my head (because I've already set up everything), so if there are any HUGE flaws, just tell me Smile

  skywire manager difficulty
Posted by: mnnr - 06-08-2018, 11:44 PM - Forum: Skywire - Replies (7)

Hi Everyone,

I'm an utter noob, I apologise in advance for my lack of knowledge. I have searched high and low for an answer to my questions, to no avail.

I'm running a single orange pi prime, using the manager/node image from github. The pi is connected to a switch, which is connected to my ISP modem router.

I can access the browser manager with the default 192.168.0.2:8000 address.

When I open the manager, the node client and node apps are running. Status: online, type: TCP.

My issue is the discover address in settings has a red exclamation mark, and when I try to change the discovery address it does not update. I am not connected to any other nodes, when I click 'search services' the window pops up and closes immediately. 

I am accessing the manager with a clean install of firefox. I have also tried chrome and edge, I experienced the same problem.

I'm totally lost at this point... Can anyone help?

  Manager node service keeps restarting?
Posted by: shokunin - 05-31-2018, 09:22 PM - Forum: Skywire - Replies (3)

I've got my DIY miner up using 8x Rpi3 B+'s and they are all shown as being online, however my manager node (2nd row) keeps restarting every 10 seconds or so as shown in the picture.  All the other nodes show online and the started duration is correct.


[Image: Screen_Shot_2018_05_31_at_2_04_42_PM.png]

Is this normal or what could I do to troubleshoot.

  My review of the official miner
Posted by: Bakez - 05-28-2018, 12:24 PM - Forum: Skywire - Replies (2)

Finally have my miner completely set up and been running for a few days now.

Thus far I am reasonably impressed. I am already streaming 4k over the VPN service, with only a few stutters.

It was very easy to set up - had the hardware set up weeks ago, and the software only took about a day to get it running, and then a few days testing things to make sure I was ready to submit my keys and for the testnet. Wish I had the time to do it a few weeks ago.
I will definitely think about buying another or making DIY miners for family. The VPN is great.

Some comments for troubleshooting:
1) When I use cisco anyconnect to log into my work network, I can no longer access the node manager page
2) The router seems buggy and needs to be reset often
3) Doing anything too fast seems to make it all crash

I hope over the next few years we can get a few 1000 regular users of skywire. Then I think the meshnet will take care of itself organically without the sky team directing it all
