oscam.conf file is the central hub for global settings in (Open Source Conditional Access Module), a software used to manage and share satellite TV smart card access. It dictates how the entire server behaves, including its networking, security, and logging. Formacionpoliticaisc Core Features & Sections The file is organized into nonrecurring sections, with the section being the only mandatory one. : Manages system-wide parameters such as process priority (
), log file locations, and initial debug levels. It also handles critical performance settings like clienttimeout (how long to wait for a key) and to block unauthorized login attempts.
: Configures the OSCam Web Interface, allowing you to set the HTTP port, access credentials (username/password), and allowed IP ranges for remote management.
: Enables communication between OSCam and the receiver's hardware, defining the user account and box type for channel decryption.
: Sets up a UDP port for real-time monitoring of server activity.
: (Optional) Used to manage the storage and sharing of previously found decryption keys (CWs) to reduce smart card load. LibreELEC Forum Key Functional Capabilities Load Balancing
: Optimizes performance by distributing requests across multiple readers using different modes (e.g., fastest reader first). Anti-Cascading oscam.conf
: Provides security features to prevent unauthorized redistribution or "cascading" of the shared keys. Protocol Support
oscam.conf is the main configuration file for OSCam (Open Source Conditional Access Module), a software used primarily in digital television systems to manage access to encrypted channels. Core Function & Structure
The file contains global parameters that control how the server operates, including logging, monitor access, and various protocols. It is organized into nonrecurring sections:
[global]: The only required section. It defines core parameters like:
logfile: Path for logging activity (e.g., /var/log/oscam.log). nice: System priority level.
clientmaxidle: Maximum idle time before a client is disconnected. Never leave default passwords: Change httppwd , monpwd
[monitor]: Optional section for configuring remote monitoring. Includes: port: The port used for the monitor interface. monlevel: Defines the level of access for the monitor. [webif]: Configuration for the web-based interface. httpport: Port for the web interface.
httpuser / httppwd: Credentials for logging into the web interface.
[dvbapi]: Configures the API for local descrambling on devices like Linux-based set-top boxes. Example Configuration Snippet
A basic oscam.conf might look like this according to examples found on GitHub:
[global] logfile = /var/log/oscam.log clientmaxidle = 36000 nice = 9 [webif] httpport = 8888 httpuser = admin httppwd = admin httpallowed = 127.0.0.1,192.168.1.0-192.168.1.255 Use code with caution. Copied to clipboard
For detailed documentation, you can refer to the official OSCam Wiki or view man pages available through FreeBSD Manuals. 2 = only fastest

oscam.confYour oscam.conf is the first line of defense against attackers. Follow these rules:
httppwd, monpwd, and all protocol keys immediately.httpallowed and allowed (in [newcamd]) aggressively.oscam user and set user = oscam in [global].[cccam] if you don’t use it.[newcamd] over [cccam] for modern setups – It’s more efficient and secure.httpreadonly = 1 after you finish configuring – Prevents web-based modifications by intruders.Caching Control Words (CW) radically reduces card load and ECM response time.

cache_cw_max_age = 12
cwcycle_check_ecmcount = 5
cwcycle_check_caid = 0963,0B00
cwcycle_maxlist = 500
max_time: Maximum age (ms) of a cached CW before it is discarded.cache_cw_max_age: Alternate age limit in seconds (ECM cycles). For 0963 Sky UK, a CW changes every ~10 seconds, so set to 10.cwcycle_check_caid: Enable CW cycle detection (prevents bad caches) for specific CAIDs.cwcycle_maxlist: How many unique CWs to store in cache per channel.The [global] section dictates how OSCam runs on the operating system. Here are the most important parameters.
If OSCam runs on a set-top box (Enigma2, VU+, Dreambox), you need [dvbapi] to send decrypted keys to the local DVB driver.

preferlocalcards (0/1): Always prioritize ECM requests to locally inserted cards over network readers. Essential for stability.lb_mode: Load balancing mode. 1 = all readers used, 2 = only fastest, 3 = weighted round-robin.lb_nbest_readers: How many of the best readers to use (e.g., 2 means round-robin between top 2 fastest).lb_reopen_seconds: If a reader fails, wait this many seconds before retrying.
