Re: Beginner Questions: spyserver.config

Ken Alexander
 

Thank you!

So those numbers work then?  I thought maybe they were just placeholders.  Usually I see things like 192.168.xx.xx.  Port numbers, I know nothing.  Maybe less than nothing!  😜
I'll give those numbers a try, right after I read that article!

Thanks again!

Beginner Questions: spyserver.config

Ken Alexander
 

Today, I'm trying to set up a Spyserver for the first time.  There are no instruction, but much of the settings in the config file look straightforward except for:

bind_host = 0.0.0.0
bind_port = 5555-6666

I know they have something to do with networks but beyond that I'm completely lost.  I'm planning to run this on a Raspberry Pi 3 and access it from across my house with SDR# running on a Windows laptop.  I assume I can do this.

Are there standard/default entries for these two settings?

Many thanks in advance.

Hmarais,
That makes sense, the 8.x.x.x WAN address I had *is* public but my host shares it with many users so it can't send incoming connections to me. Now I understand, thanks!

Re: Spyserver Online/Unreachable Issue

hmarais@...
 

In the case of carrier grade NAT, which is what Bill's situation is, your router's WAN address is a private, non-routable address. The ISP then NATs a bunch of people behind one public IP. So the IP address your dynamic DNS service picks up is shared by many connections and, unless you have control of your ISP's networking equipment, means you can't port forward to devices on your LAN.


Re: Spyserver Online/Unreachable Issue

That is what port forwarding is for in your router, that gets you to the specific address in your network.  I use it for my video security camera, each has there own 168.192.xxx.xxx address, several different PCs, and an ftp server.  Each device is associated with a specific port number that I assigned in the router so it knows what address to send the packets to.

If you do an nslookup on the "associate ip name" you'll find it does not map to the 192.168.xxx.xxx address. Name or not, that can't show up on the internet.

Re: Spyverter R2 with USRP B210 #shortwave

For what it is worth DC->60 MHz is shifted to BOTH 120-180 MHz and 120-60 MHz. It's called imaging. 1MHs appears at both 121 MHz and 119 MHz on the output of a mixer. Filtering on the mixer output can remove the image if it becomes bothersome. Done wrong it will also remove the spectrum near DC, probably up to over 2MHz with reasonable circuit element Qs. This is clearly shown in the second picture. The first picture may be not showing the broadcast band due to filters and possibly a very small antenna.

Eric,
I'm fortunate to have a rather new, lean, mean, and hungry provider "Greenlight Networks." Little by little they've been running fiber in the Rochester, NY area. I have their entry-level plan which until recently was 100mbbs, then Spectrum Cable started advertising 100mbps so Greenlight stuck it to them by upgrading everyone to 500 for free...the way competition is supposed to work. For most things I find it really doesn't make much difference becaust the former 100mbps was rarely the bottleneck.

Ahh, I looked again at the picture I posted, and I DO see the symmetry either side of 120MHz.... I'll set that as the offset, but as I said earlier, it didn't match to expected stations freqs.

I'll give it another go.

Thanks again.

Not sure if you fully understand how converters (or any RF mixers) work, but that's perfectly expected. The signals are mixed with a 120 MHz LO. The positive image falls between 120 and 180 MHz, and the negative (inverted) image falls between 60 and 120 MHz. OTOH, the BPF at the output is optimized to attenuate the harmonics, not the negative image.

Yes the 192.168.xxx.xxx is not reachable but the associate ip name (not sure of the correct term) is.  So use the name instead of the actual address.

No-IP won't help at all if your WAN internet address isn't routable. If your WAN address is 10.x.x.x, 192.168,x,x or 172.(16-32).x.x nothing will make it appear on the internet. All No-IP does is regularly check your DHCP assigned address in case it changes and provide that via DNS using a name like "yourname.noip.com.

When I discovered this issue I had been assigned a WAN address like 8.x.x.x which by the internet RFC's should have been routable. I believe my ISP found an unused block and decided themselves not to route it. Not a good plan and it could bite them!. Other than this issue I really like my provider, they have fiber right into my house and give 500mbps down and 50mbps up for $50/month; the reliability has been good. For an extra $10/month they now give me a static IPV4 address and spyserver works like a charm with it. And since the IP address never changes I don't need something like No-IP.

Re: Spyserver Online/Unreachable Issue

How did you manage to score a 500MB connection for that low a price? Here in Phoenix, if I want fiber, it will run me north of $200 monthly. Btw, I still need to get one of these devices and setup a spy server here. Right now, though, my income being severely limited by disability makes that rather hard to do.

Btw, I have a couple of the RTL/SDR USB devices using the more common RT series decoders in them. Any way to set this up to work with spy server on OS X? And yes, I do have a static/routable IP here, so all I would need to do is forward the correct ports.

Re: Spyserver Online/Unreachable Issue

I guess your ISP uses a technology which is called DS-lite:

https://www.juniper.net/documentation/en_US/junos/topics/concept/ipv6-dual-stack-lite-overview.html

In Europe this is very common as we are, as you possibly know, running out IPv4 addresses. 

SpyServer can only handle IPv4 addresses. To make your PC accessable through the IPv6 barrier you have to use a service which provides a universal port mapper. F. i. something like this: http://www.feste-ip.net/dslite-ipv6-portmapper/universelle-portmapper/. As this is a german site you should use Google translator to read this. I do not know of any site in english language which provides such a service. Probably there are such.

To make SpyServer communicate with IPv6 addresses you can use a program like Socat for Windows https://github.com/tech128/socat-1.7.3.0-windows . 

As I said in my earlier post it would make more sense, if SpyServer got an update to enable it to deal with IPv6.
