When building a large server (e.g., 20+ local cards and 50+ remote peers), you must optimize resources.
We are assuming you are running Linux (Ubuntu/Debian) with a physical card reader (like a Phoenix or Smargo) or an internal CI slot.
Do not put all readers in group 1. Instead:
Then assign users to appropriate groups via oscam.user.
The oscam.server configuration file is the heart of any OSCam-based sharing system. It controls how your local cards are read, how you connect to external peers, and how requests are load-balanced. By carefully setting parameters like group, au, blockemm, fallback, and lb_weight, you can build a robust server that delivers fast channel zapping and stable decrypts.
Remember: Always test changes in a safe environment, monitor logs for errors, and never share your config files publicly. As television encryption evolves, OSCam adapts—but the core logic of its server config remains a timeless piece of engineering for conditional access enthusiasts.

Oscam (Open Source Conditional Access Module) is the most versatile software for managing satellite and cable subscriptions across various receivers like Enigma2 boxes. Setting up an Oscam server requires precision to ensure stable, glitch-free viewing.
This guide provides a comprehensive breakdown of how to configure your Oscam server files for optimal performance. Understanding the Core Configuration Files
An Oscam setup relies on three primary files located in the /etc/tuxbox/config/oscam/ (or similar) directory. Each file serves a specific purpose: oscam.conf: The main system settings.
oscam.server: The reader/source settings (where your cards or lines are defined).
oscam.user: The account settings for local or remote clients. Phase 1: Configuring oscam.conf
This file acts as the "brain" of the server. It manages the web interface, global timeouts, and the protocols used to share the signal. Key sections to include:
[global]: Set your logging parameters here. Set nice = -1 to give Oscam high CPU priority.
[webif]: Essential for managing your server via a browser. Define your httpport, httpuser, and httppwd. oscam+server+config
[dvbapi]: Necessary if you are running Oscam on the same box you use for watching TV. Ensure enabled = 1 and user = localuser. Phase 2: Configuring oscam.server
This is where you tell Oscam where to get the decryption keys. You are essentially defining "Readers."
For a Physical Smartcard:You must define the protocol (usually internal or mouse), the device path (like /dev/sci0), and the caid specific to your provider.
For a Remote Proxy (CCcam/Newcamd):If you are connecting to another server, your config should look like this: Protocol: cccam Device: address.com,port User/Password: Your credentials
Group: 1 (Groups are vital for organizing which users access which readers). Phase 3: Configuring oscam.user
Without this file, no one can connect to your server—not even your own receiver. Account Name: Matches the user in oscam.conf (DVBAPI).
Group: Must match the group number assigned in oscam.server.
Au: Set to 1 if you want the user to be able to send EMM updates to the card to keep it active. Optimization Tips for Stability
Keep Groups Organized: Assign your local card to Group 1 and external proxies to Group 2. This prevents "looping" and reduces ECM times.
Manage Timeouts: In oscam.conf, set clienttimeout to roughly 5000ms. If a key doesn't arrive by then, the system should stop waiting to prevent freezing.
Use the Web Interface: Instead of manually editing files via FTP, use the "Files" tab in the Oscam WebIf. It validates syntax and allows for instant restarts. Troubleshooting Common Issues
"Rejected Group": This usually means the user’s group in oscam.user does not match the reader’s group in oscam.server.
High ECM Times: Check your internet stability or ensure your smartcard reader frequency (mhz) matches the card’s specifications.
Black Screen: Ensure the dvbapi user in oscam.conf has a corresponding entry in oscam.user. When building a large server (e
To help me give you the exact code you need, could you tell me:
What hardware are you using (e.g., Dreambox, VU+, Raspberry Pi)? Are you using a physical smartcard or a remote proxy line? Which satellite/provider are you trying to decrypt?
I can provide a ready-to-paste template once I have those details.
To configure an OSCam (Open Source Conditional Access Module) server
, you need to manage three primary configuration files. These files control how the server handles card readers, connects to clients, and manages global system settings. 📂 Core Configuration Files 1. oscam.conf (Global Settings) This is the main file that defines the web interface load balancing : Set log destinations, debug levels, and user priorities.
: Enables the browser-based management tool (default port usually 8888). [newcamd] / [cccam] : Defines the server ports and keys for client connections. 2. oscam.server (Reader Definitions)
This file tells OSCam where to find the "source" of the keys (the smartcards or remote proxies). : The physical path to your USB card reader (e.g., /dev/ttyUSB0 : Specifies the reader hardware type (e.g., smartreader : A numeric ID used to "match" readers to specific users.
: The Conditional Access ID specific to your service provider. 3. oscam.user (Client Accounts)
This file creates accounts for the devices (STBs) that will connect to your server. : Credentials for the client to log in. : Must match the group ID defined in oscam.server for the user to receive keys.
: Enables "Auto-Update" to keep the smartcard entitlements current. 🛠️ Step-by-Step Feature Setup Step 1: Secure the Web Interface
Always set a password for the WebIF to prevent unauthorized access.
[webif] httpport = 8888 httpuser = admin httppwd = your_secure_password httpallowed = 127.0.0.1,192.168.1.0-192.168.1.255 Use code with caution. Copied to clipboard Step 2: Define a Local Card Reader
If using a physical card, you must define its parameters so OSCam can "talk" to it.
[reader] label = my_local_card protocol = mouse device = /dev/ttyUSB0 caid = 0500 group = 1 Use code with caution. Copied to clipboard Step 3: Create a User Account Then assign users to appropriate groups via oscam
Grant a local device access to the card reader defined in Group 1.
[account] user = bedroom_box pwd = pass123 group = 1 au = my_local_card Use code with caution. Copied to clipboard 💡 Key Features for Stability Load Balancing
: If you have multiple readers for the same provider, OSCam can distribute the "hits" to prevent card freezing. Anti-Cascading
: Prevents users from resharing your keys to other unauthorized devices.
: Automatically switches to a backup reader if the primary one goes offline.
: Essential for local descrambling if you are running OSCam directly on a Linux-based satellite receiver (like an Enigma2 box). To help you with a specific configuration , could you tell me: are you using? (e.g., Raspberry Pi, Enigma2 Box, PC) card reader do you have? (e.g., Smargo, Easymouse 2, Internal) do your clients use? (e.g., CCCam, Newcamd, Mgcamd) I can then provide a ready-to-use template for your exact setup.

Don't run OSCam in a screen session. Use systemd.
Create /etc/systemd/system/oscam.service:
[Unit] Description=OSCam Card Server After=network.target[Service] Type=forking User=oscam Group=oscam ExecStart=/usr/local/bin/oscam -b -c /etc/oscam -t /tmp/.oscam ExecReload=/bin/kill -HUP $MAINPID Restart=on-failure RestartSec=5
[Install] WantedBy=multi-user.target
Enable it:
sudo systemctl enable oscam && sudo systemctl start oscam
