Thread: Help With BoxKey And SCAM

Hello d4g,

Did you get this to work?
I have been trying to get scam to be server and client on my DM7025.
I have put the sc_videoguard in /usr/keys/. chmod is 644

Code:

I: { AAAA BBBBBBBB { CCCCCCCC }}
# where:
# A = CA System ID
# B = Card Serial
# C = Box key

I got the serial and boxkey from oscam log file on startup.

I have config file in /usr/scam and /etc/scam just to be sure. chmod is 644.

Code:

### scam host
/net/ecm_server/homeserver/port=4321
/net/ecm_server/homeserver/user/client1/pass=test

### scam client
/net/ecm_client/homeserver/host=192.168.0.100
/net/ecm_client/homeserver/port=4321
/net/ecm_client/homeserver/user/client1/pass=test

I know that scam is running ok because it reads the /usr/keys/irdeto file and I get pics for Aurora.
It just does not seem to see the ND$ card.
Any tips?

The hexadecimal smart card serial number to enter is just the hexadecimal conversion of the decimal serial number on the card (but with the redundant last digit on the card removed). If you have Oscam the hex version is printed in the logs.
So if your smart card serial number is e.g.: 0002 0898 7406
You would first remove the redundant last digit (6) then do a hexadecimal conversion of 20898740 which would be converted to 013EE3B4 and you enter that in the place of the BBBBBBBB section of the I: line. Remember to pad out the number with zero in front so that it is 8 hexadecimal digits in length.

The box key is the same as per all softcams in hexadecimal format.
So if you have an orange then after the above conversions you should have something like this line only in your sc_videoguard file:

I: { 096C 013EE3B4 { 12AB12AB }}

If you had a bluey would you need to enter a boxkey or just a string of zeros?

The box key for both orange and blue is not zero in either case. It is a non-zero number that must be correct. Some softcams can auto-detect for blue but given that Scam can't even auto-detect the card serial number I would assume anything but the correct box key and serial number won't work.
It's not rocket science to just enter the correct box key anyway.

The last digit on the card and the last digit on the boxid sticker aren't redundant, they are checksums. Probably there to check any numbers given over the phone or by other means are correct.

That's why they need to be removed when converting from decimal to hex.

You're correct. They are indeed a checksum value used to indicate the validity of a card number, but for the purposes of creating a hexadecimal value from the true sequential serial number value that last digit is redundant.

Thanks for the info, I wasn't aware that the blue card had a boxkey but that's just my noobness.

I did a search before I posted and from this post I saw you were unaware of the significance of the check digit. That is why I posted about the digit not being redundant.



When you quoted my post you left out this line in which I did say it was necessary to remove it for conversion purposes.

That's why they need to be removed when converting from decimal to hex.

Some people have no idea of anything other than base 10. The metric system doesn't help in that regard. Some of us who were used to ounces and pounds were working in base 16 before we even knew what that meant.

Davmel: I gained my Serial Number and Box ID from oscam log file and inserted them into the /usr/keys/sc_videoguard file. This file is chmod 644.

Code:

I: { 090B 00FFAABB { 11223344 }}

I have deleted the contents of /etc/scam/config file in the hope of it being able to just serve to itself, but still nothing with ND$. It did not auto populate the file.
The scam debug output is:-

Can you recommend anything else to try?

This is the problem

d0 7e 11 00 01

The blue card doesn't support ins7e

Thanks for the reply nexus, but I am confused.
Does this mean that scam is not a suitable server for Blue card?

From that log it looks like a no go with that version for a bluey unless there is a config setting or command line argument that will get it to change it's startup.

I can see a discrepancy here. Unless your /usr/keys directory is symbolically linked to your /var/keys directory then Scam is not seeing what is in your /usr/keys directory.
Can you confirm?

Also, as for your box key, can you confirm that the box key is the correct one by doing a manual conversion yourself rather than relying on the auto-detected value provided by Oscam?

Thanks for the patience davmel.
Yes there is a symbolic link for /var/keys pointing to /usr/keys.
I have just manually calculated the Card Serial and Box Key and the come out with the same value as the ones from the oscam log.
