Topic: How do you communicate with your Antminer S2 outside your network? (Read 8133 times)

Teamviewer works great as a windows-based solution if you want to avoid all the headaches associated with port-forwarding, etc.

Just setup some sort of proxy-system with teamviewer installed that has access to all the subnets for S2's that you want to be able to access.  You can then either access the web-interface or download putty and ssh into the box.

hamatsi try it other wise I have been told to use a VPN server
give us feedback when you solve it I need more info too

I have Teamviewer install to manage my home computer, so I just use that as well. 

Your best bet is probably using an ssh tunnel into the network.  That way (assuming you have a machine that's always on) you don't have to advertise any ports except ssh.  You should also turn off password authentication add fail2ban etc.  One command on your laptop opens the tunnel and then you'd pull up the same internal ip on a different port from your laptop.

@Pathi - That's what I was going to do in the next couple days if there was not an alternative that anybody found. I figured asking for an alternative or hearing what others use would be a good start first.

@sp1 - Unfortunately the Antminer S2 (newest firmware) internal menus are not the same as the S1. A lot more power, but just with basic configuration without any of the settings you're describing. Looks like I'm setting up a sock-puppet box for this. Opening it up to the internet has already crossed my mind and I don't trust it to do it itself at this point.

Thank you everyone so far for giving this a look through or responding to this post.

Check if the antminer has some sort of firewall that only lets it connect to computers on the same subnet.  Also check if you need to forward https port as well.  But, I think it's a bad idea to expose it to the internet.  I can't imagine that it's hardened against attack.

I have several systems at my home that I like to access remotely. What I have setup is an old desktop with vnc running on it. I have a dns entry at dyndns.net that points to this box.

I remote into this computer, then run the config page for my miners. I also have the ability to rdp into my other windows boxes, or ssh into my Linux box. From this computer.

A couple of notes:
Do not put anything important on the computer visible to the internet.
Do not use the same username/password combo for any of the systems you will access from this computer.
Personally I have vnc restricted to a couple of mac addresses to tighten things up a little more.

Set your incoming port to some random 4 number port. Outgoing is 80.

Then you would connect to your external IP address:4numberport

such as 123.123.123.123:1234 > 192.168.1.99:80

root:root becomes out of the question, though. You'll need to strengthen your password to the miner.

I figured you must have, but thought I'd throw out the obvious choice first .

I did just that and the results were receiving the output I described above through FireFox and chrome.

Wouldn't you just setup a port forwarding rule on your router to send port 80 to 192.168.1.99?

Salutations everyone,

I've been mining a while with some Antminer S2's in different pools to test out the configuration. I only access it through the web browser from my home network on my laptop running Win7 x64. The router is a MI424WR-GEN3I (frontier service). I'm looking for a way to access it outside my network in the same way through the browser ideally. So I can change the mining configuration while out and about.

I have it on the static address (192.168.1.99), each time I switched it to DHCP the Antminer would not work correctly. I signed up for no-ip.com for DDOS to attempt to forward the access out. But after creating the last port forward rule for my Antminers address on my home router, it still isn't working correctly.

Currently when I access my home network/port (assigned to the Antminer) through Firefox. It shows the following:

CMD=GET / HTTP/1.1
Host: XXXXXXXXXXX (My network address/port)
user-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:30.0_ Gecko/20100101 Firefox/30.0
Accept: text/html\,application/xhtml|STATUS=E,When=1402685318,Code=14,Msg=Invalid command,Description=cgminer 3.12.0|CMD=xml\,application/xml;q\=0.9\,*/*;q\=0.8

Accept-Encoding: gzip\, deflate
Connection: keep-alive

|STATUS=E,When=1402685318,Code=14,Msg=Invalid command,Description=cgminer 3.12.0|

It looks like to me I'm opening up a file/packet from cgminer. When I attempt to access it through Chrome it starts an instant 566kb file to download. Opening up the file in Notepad++ shows the same values shown above in Firefox.

Anyone know what port forward settings I need to use to have it come up correctly? If you have another way that you use to access your Antminer S1/S2 system from your home network outside it, please share it.

As a side note, I also suggest everyone that owns an Antminer S2 reads over [Dogie's Comprehensive Bitmain AntMiner S2 Setup]https://bitcointalksearch.org/topic/guide-dogies-comprehensive-bitmain-antminer-s2-setup-hd-518205 as well. It goes over a great deal with common and some complex issues that have been experienced so far with this hardware.

Thank you for your time and good luck mining!
