About oscam use: how to avoid my clients send to my server decoding requests for providers - caid etc that my server can't help to decode (not having the necessary card).

Hi.

There are several options.

On the softcam server, if it is Oscam, you can specify one CAID or several CAIDs for each user, which they are allowed to use. You can do this in the file "oscam.user" (https://wiki.streamboard.tv/wi…en/Config/oscam.user#caid) or directly via Oscam Webif (WebGUI), directly in the settings of a specific user.

[account]
user        = user1
pwd         = password1
caid        = 0624,0D96
group       = 1

You can also specify directly on your server that you use only a specific CAID or multiple CAIDs. First, directly in the "oscam.reader" file, by writing a parameter (https://wiki.streamboard.tv/wi…/Config/oscam.server#caid).

Furthermore, if it is a newcamd protocol and not a cccam protocol, you can also specify the CAIDs used on the softcam / Oscam server (https://wiki.streamboard.tv/wi…/Config/oscam.conf#port_6), for a specific port, such as:

[newcamd]
key     = 0102030405060708091011121314
port    = 14000@0624:000000;14001@0D96:000004

Finally, it is advisable to set priorities and ignore CAIDs on the device (configuration file: "oscam.dvbapi"), where you have your Oscam server, i.e. where you have your shared cards / CAIDs (https://wiki.streamboard.tv/wi…am/en/Config/oscam.dvbapi). For example, as follows:

#### Setting priority rules for CAIDs (user_dvbapi):
P: 0624     # Skylink SK (Irdeto)
P: 0D96     # Skylink SK (CryptoWorks)

#### Ignore every CAID that was not handled before:
I: 0

Or you can also set the CAID(s) directly in the softcam client connection:

However, it depends on which softcam client you use. Cccam softcam or Oscam softcam - are set differently (there is a different configuration file). For example, in Oscam softcam, under the file "oscam.server", where you create a connection to a remote reader (to a external softcam), you can also add a CAID parameter there - as if it were a physical card reader (I mentioned the URL above).
