Oscam+server+config May 2026

Configuring an OSCam (Open Source Conditional Access Module) server involves three primary files: oscam.conf, oscam.server, and oscam.user. This report outlines the standard setup for a stable server as of early 2026. 1. Global Configuration (oscam.conf)

This is the main file that defines how OSCam behaves, including logging, the web interface, and active protocols. [global]: Sets system-wide parameters. nice = -1: Sets the system priority for the OSCam process.

logfile = /var/log/oscam.log: Defines where activity logs are stored.

clienttimeout = 5: The time (in seconds) the server waits for a key before timing out. [webif]: Enables the browser-based management tool. httpport = 8888: The port used to access the Web Interface.

httpuser / httppwd: Credentials for logging into the Web Interface.

httpallowed = 127.0.0.1,192.168.0.0-192.168.255.255: Restricts access to local network IPs.

Protocols: Define how clients connect. Popular options include [cccam] and [newcamd]. Example CCCam: port = 40000, version = 2.3.2, reshare = 1. 2. Reader Configuration (oscam.server)

This file tells OSCam where to get the decryption keys—either from a local physical card or a remote server. oscam.conf - openpctv - GitHub

Introduction OSCam (Open Source Conditional Access Module) is the Swiss Army knife of satellite and cable television software. Unlike standard proprietary decoders, OSCam is a softcam—a software-based emulator—that handles the decryption of subscription television signals. At its core, an OSCam server acts as a centralized hub that manages smartcard access and distributes "Control Words" (CWs) to various clients within a local network. The Core Configuration Files

Setting up an OSCam server requires configuring three primary text files. Each serves a specific purpose in the communication chain: 1. oscam.conf (The Brain)

This is the global configuration file. It defines how the OSCam process behaves, which network protocols it uses (like Newcamd or CCcam), and how the web interface (WebIf) is accessed. oscam+server+config

WebIf: Essential for beginners, it allows you to monitor traffic and edit configs via a browser.

Protocols: You must define a port and a "DES key" for protocols like Newcamd to allow external or internal boxes to connect. 2. oscam.server (The Source)

This file defines your "Readers." A reader is the source of your decryption keys. This could be a physical USB card reader (like an Omnikey or Smargo) holding a legal subscription card, or a remote proxy server. Device: Points to the hardware path (e.g., /dev/ttyUSB0).

Group: A critical parameter. Every reader must belong to a "group" (e.g., group = 1). Clients can only access readers if they are assigned to the same group number. 3. oscam.user (The Clients)

This file manages access control. Every device in your home that wants to watch TV needs an entry here. Account: Defines the username and password.

Group: Matches the user to the reader groups defined in oscam.server.

AU (Auto-Update): If enabled, this allows the client to send "Entitlement Management Messages" (EMMs) back to the server to keep the smartcard's subscription active. Security and Optimization

A well-configured server prioritizes low "ECM times"—the speed at which a key is cleared. High latency leads to picture freezing. To optimize this, users often use oscam.dvbapi to prioritize specific provider IDs (CAIDs) and ignore others, preventing the server from wasting time on incorrect decryption attempts.

Security is equally vital. Because OSCam communicates over a network, using strong passwords, non-standard ports, and IP whitelisting is standard practice to prevent unauthorized access to the card's resources. Conclusion

OSCam’s power lies in its modularity. While the initial learning curve is steep due to the technical nature of CAIDs, PIDs, and serial protocols, the result is a highly stable, multi-room viewing environment. By mastering the relationship between the Server (global settings), the Reader (the source), and the User (the destination), you can create a seamless television experience across your entire local network. Configuring an OSCam (Open Source Conditional Access Module)

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. Label : Give your reader a name

[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

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.

1. Setting Up Readers

  • Label: Give your reader a name.
  • Protocol: Can be internal for built-in card readers or other protocols for external devices.
  • Device: Path to the device (e.g., /dev/sci0 for a DVB card reader).
  • CAID & Ident: Specific to your card; research these values for your provider.

oscam.user – Client Access

[account]
user                          = livingroom_tv
pwd                           = securepass
group                         = 1
au                            = 1
uniq                          = 2
monlevel                     = 0

Basic Structure of a Local Card Reader

[reader]
label                         = local_card
protocol                      = internal
device                        = /dev/sci0
cardmhz                       = 357
mhz                           = 450
group                         = 1
emmcache                      = 1,3,2
blockemm-unknown              = 1
blockemm-g                    = 1
au                            = 1
caid                          = 0x1830
detect                        = cd
mhz_auto                      = 1

Key Parameters Explained:

  • label : A unique name for this reader. Used for logging and client assignments.
  • protocol : Options include internal (internal smart card reader), mouse (serial phoenix), smargo, smartreader, pcsc, or network (for remote peers).
  • device : Path to the reader. For internal: /dev/sci0, /dev/sci1. For USB: /dev/ttyUSB0 or SmartReader:123456 (using serial number).
  • group : Integer (1-255). Clients are assigned to groups. A client in group 1 can use a reader in group 1. This is your primary sharing control.
  • au (Auto Update): Set to 1 if this card needs to receive EMMs (Entitlement Management Messages) to keep its subscription alive.
  • caid : Conditional Access ID (e.g., 0x1830 for Nagra, 0x0500 for Viaccess). Optional but helps OSCam prioritize.

Mistake #3: Not Setting au = 1 on the Card’s Home Reader

If you have multiple readers with the same CAID, only set au = 1 on the reader physically holding the card that needs updates. All other readers for the same provider should have au = 0.

7. Security Best Practices

  • Do not expose OSCam directly to the internet without VPN (e.g., WireGuard/OpenVPN)
  • Change default web interface port from 8888
  • Use strong passwords in oscam.user
  • Enable keepalive and fallback to prevent abuse
  • Regularly update OSCam to latest stable version (security fixes)
  • Monitor oscam.log for unauthorized access attempts
