I have found 100% pre configured OSCAM file in IPK format. After installation you will get all needed files and settings to use any SoftCam.Key file. There is even 1 file included in this installation.
All you need to do is install this ipk package through telnet.
Inctruction:
-Download DCC v2.9.6 to your computer and start it
-Check the IP address of your receiver and connect to your enigma2 sat receiver
-Go to FTP section in DCC program
-copy the attached file "enigma2-plugin-softcams-oscam-11-711-emu-r798-all.ipk" to your media/hdd or media/usb directory in your box (you need to have usb or hard drive connected to your box through the USB port)
-Go to Telnet section in DCC and type:
opkg install media/hdd/enigma2-plugin-softcams-oscam-11-711-emu-r798-all.ipk
-installation of this OSCAM package should start straight away
To start using new oscam package you need to restart your enigm2 box.
Now you will find all new config files in your receiver in: etc/tuxbox/config
I think this is the easiest way to setup OSCAM to work with any SoftCam.Key file.
This setup also works excellent for all clines. You just need to paste your cline details to oscam.server file.
