Oscam Server Config !link! May 2026

Understanding and Configuring an OSCam Server

OSCam (Open Source Conditional Access Module) is arguably the most popular, open-source softcam software used in the Linux satellite and terrestrial reception community. It acts as a card server, reading subscription smartcards and distributing the decryption words (Control Words) to client software or other receivers on a network.

While OSCam is powerful and supports virtually every card protocol, its complexity can be daunting. The configuration is entirely text-based, usually involving three primary files located in the configuration directory (commonly /etc/tuxbox/config/ or /usr/local/etc/).

Below is a breakdown of the essential configuration files: oscam.conf, oscam.server, and oscam.user.

---

oscam.conf — global server settings (essentials)

Key sections and recommended settings:

• [global]

  • logdir = /var/log/oscam
  • cachedir = /var/cache/oscam
  • maxlogsize = 1000000
  • maxloghistory = 5

• [webif] (web interface)

  • http = 8080
  • httpuser / httppwd — set strong credentials
  • httprefresh = 3
  • encpasswd = 1 (store encrypted password)

• [dvbapi]

  • enabled = 1
  • host = 127.0.0.1
  • port = 9000

• [monitor]

  • keepalive = 60

Notes:

• Use local loopback 127.0.0.1 for services you don’t want public.
• Enable only the services you need.
• Keep log rotation in mind on production systems.

Sample minimal excerpt:

[global]
logdir = /var/log/oscam
cachedir = /var/cache/oscam
[webif]
http = 8080
httpuser = admin
httppwd = secret
encpasswd = 1

Install dependencies

sudo apt install build-essential libssl-dev libusb-1.0-0-dev cmake git -y

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.

ECM Whitelist (Filtering)

ECM whitelists tell the reader to ignore certain PIDs (Packet Identifiers), forcing faster cache hits. oscam server config

[reader]
...
caid                          = 1810
ecmwhitelist                  = 1810:4264,4265,4266

Only ECMs with CAID 1810 and the listed PIDs will be processed.

3. The Users: oscam.user

This file defines which clients are allowed to connect to the server and what permissions they have.

Configure and build

mkdir build && cd build cmake -DWEBIF=1 .. make sudo make install

Alternatively, use precompiled binaries from trusted sources. Understanding and Configuring an OSCam Server OSCam (Open

Log message: Reader my_proxy (cccam) connecting to server failed: Connection refused

• Cause: Remote server is offline, port is wrong, or firewall blocks access.
• Fix: Verify the device IP/port. Check if remote server allows your IP (some have allowed_ips lists).
