blockemm-unknown = 1 blockemm-s = 1 blockemm-g = 1 blockemm-u = 1 This prevents remote users from sending updates to your card. Only you (via local AU) should update entitlements. Never set cccmaxhops higher than necessary. Hops of 3 or more introduce latency and risk card cloning. A typical safe limit is 2 . 4. Use Strong Passwords in Newcamd The key parameter in Newcamd should not be default ( 010203... ). Generate a random 28-character hex string. 5. Bind Readers to Specific Network Interfaces (Advanced) If your server has multiple IPs, use:
[reader] label = card_one caid = 0D95 group = 1 ... [reader] label = card_two caid = 0D95 group = 1 ... OSCam distributes requests based on response times (Round Robin or Least Load – configurable in oscam.conf under [cache] ). To reduce load on your local card, enable Cache Exchange in the reader: oscam server config
Introduction In the world of satellite and cable television, OSCam (Open Source Conditional Access Module) stands as the most powerful and versatile software for sharing and managing decryption keys. Whether you are a hobbyist building a home TV distribution system or a network administrator managing a complex receiver setup, the core of your operation rests on one critical file: the oscam.server configuration. blockemm-unknown = 1 blockemm-s = 1 blockemm-g =
[reader] ... cacheex = 1 cacheex_maxhop = 2 cacheex_mode = 1 This allows your reader to serve cached ECMs from other clients, drastically lowering the number of actual card accesses. Misconfiguring oscam.server can expose your card to theft or flooding attacks. Follow these rules: 1. Never Use Default RSA Keys If your reader definition includes an RSA key (like Nagra or Viaccess v4+), ensure it is exactly the key extracted from your original card or box. A wrong key will not work. A leaked key compromises your card. 2. Block External EMMs Always include: Hops of 3 or more introduce latency and risk card cloning
