Hey all,
Is it possible to get Freq/NetID/Symbol rate after a brute-force search? A mate doesn't know anyone in his area that has a digital subbed box so is doing a brute-force scan.
Is there anyway of getting the Freq/NetID/Symbol rate by looking at the services file?

Update: Yes, I post before I really look closely at the files.
<transponder id="0003" onid="*HEXNUMBER*" frequency="386000000" inversion="2" symbol_rate="6887000" fec_inner="3" modulation="3">

So if yea convert the Hex number thats in the *HEXNUMBER* section yea get the NetID and yea see the symbol tate is 6887.
But what about Freq yea might ask.
This is the list of Freq it finds channels:
338000000
274000000
354000000
290000000
370000000
306000000
386000000
322000000
258000000

How do yea find the one yea use? Just use the lower one.

Hi kerbdog,

I tried this on my "services.xml" file since I do not have a digital subscription box, only an anloague one.

My setting for onid=f020.

Do you have to convert the 'onid' from Hex to decimal?
When I try to convert from Hex to ASCII I get a weird number, 66303230.
When converting from HEX to decimal, I get 61472 which looks more likely.

Thanks

Ah great, at least someone found it useful.

axeman: Go to this page,

Throw in your hex number and yea get the decimal number :)
Your NetID is 61472

Thanks Kerbdog!

I thought that it was correct to convert it into decimal.
The only thing that is weird is that nobody else seems to have a Net id of 61472. They all seem to start with 4..... or 0.....
I am based in Northolt, Middlesex, NTL EX-C&W.

Well, thanks again.

PS.: Maybe this method should be added to the sticky '### Post Your Own Net-Ids ###' since I have seen ppl asking how you can retrieve this info from a Dbox several times before.

That's not the netid, it's the onid - original network id.

They're 2 different things.
 
Weird, the conversion worked for me and a mate.

So what is the original network id?
 
You could try the dvbsnoop plugin and do a NIT scan. It looks like the meaning of network-id and onid is interchanged in some lines of the log output.

I'll try that tonight and post my findings.
 
/tmp/dvbsnoop-bin-ppc-1.4.00-api3/bin-ppc-api3 # ./dvbsnoop 0x10 | grep Network_ID
Network_ID: *NUMBER* (*HEXNUMBER*) [= --> please lookup at http://www.dvb.org]

Yep, thats my NetID of my cable :) Thanks mgb


Just a note, my 'Network_ID' and 'original_network_ID' are the same, prob because of the MMDS Digital service.

I would trust only a logout put from a complete NIT scan.
The default frequency for NTL mmds should be 250.000. I heard something about that.

Doesn't it just scan one packet at a time? So if you get the same result after 5-10 packets you can be sure its good info?
