OScam servers: setup and configuration in 2026

Today, OScam servers remain one of the most popular solutions for sharing satellite cards. I have spent a lot of time on their setup and configuration, and I can say that proper configuration is the key to successful operation. If you want to understand the structure of configuration files, exchange protocols, and ports, you have come to the right place.

What is an OScam server and how is its architecture structured

OScam is a universal gateway for working with access cards. It can simultaneously act as a server, client, and proxy. It is important to understand that OScam works with readers (card sources) and accounts (clients). Thus, different roles can be configured in one installation.

Roles: server, client, and proxy in one installation

Each of the roles has its own tasks. The server manages the readers and responds to client requests. Clients, in turn, request access to channels through the server. The proxy allows requests to be passed between servers, which is convenient for multi-level schemes.

Where the configs are physically located

OScam configuration files can be located in different places depending on the build. By default, this can be/usr/local/etc/,/var/keys/, or/etc/tuxbox/config/oscam/. If you used the--config-dir parameter during the build, the paths may change. It is important to know where to look for configs so as not to get lost.

How OScam determines paths and why it breaks

OScam determines the paths to configuration files based on the specified parameters. However, if you did not specify the correct path or forgot about--config-dir, this can lead to problems. Users often encounter errors related to missing files, so it is important to keep an eye on this aspect.

Key configuration files and their syntax

Let's examine the key configuration files that you will need to set up OScam servers. The main files areoscam.conf,oscam.server andoscam.user.

oscam.conf — global parameters and web interface

In the fileoscam.conf, global parameters are defined, including web interface settings. For example, in the[webif] section, you can specify thehttpport that will be used to access the OScam web interface. Be sure to specify the port on which the web interface will be available to conveniently manage the server.

oscam.server — description of readers and sources

Fileoscam.server configures readers. Here you specify the protocol (for example,cccam ornewcamd), devicedevice, groupgroup and versioncccam cccvversion. Example section:

[reader]

oscam.user — client accounts and groups

Inoscam.user you create client accounts. Here you specify[account], username and password, group, as well as filterscaid/ident. It is important to understand that the relationship between reader groups and accounts is a common mistake for beginners. For example:

[account]

oscam.services and oscam.dvbapi for filtering

These files help filter access to certain channels and services. With their help, you can configure which services will be available to clients and which will not. This is especially relevant if you have many clients with different needs.

Ports and exchange protocols: CCcam, CS378x, Newcamd

When configuring OScam servers, it is important to understand which ports and protocols you will be using. Usually, these are:

• CCcam: port 12000
• CS378x: TCP
• Newcamd: port 15000+

Each protocol has its own features and settings that must be taken into account during configuration.

CCcam protocol (port 12000 by default) and cccam node id

CCcam is the most widely used protocol. It uses port 12000 by default, but you can change it in the[cccam] section of theoscam.conf file. It is important to remember that to connect to the server, the client must know not only the port but also the node id.

CS378x as a secure alternative to camd35

CS378x operates over TCP and provides reliable data delivery. This makes it a preferred choice for unstable connections. If you have issues with packet loss, CS378x will be the best option.

Newcamd (port 15000+) and DES key structure

Newcamd uses DES encryption for data transmission and can operate on ports above 15000. It is important to specify the key correctly in the configuration. For example:

[newcamd]

How to choose a protocol for a specific task

The choice of protocol depends on your tasks. If high security is required, it is better to choose CS378x. For ease of setup, CCcam is suitable. Newcamd is an interesting choice for those who want to experiment with encryption.

Connecting servers to each other and setting up reshare

Configuring the connection between OScam servers allows for the creation of multi-level schemes. This is useful if you have multiple card sources.

Configuring an outgoing reader to another server

To configure an outgoing reader, inoscam.server you need to specify the remote source. For example:

[reader]

Reshare parameters, cccreshare and cccmaxhops

The parametersreshare andcccmaxhops allow you to control the depth of sharing.cccreshare is responsible for card retransmission. For example, to limit the number of hops:

cccmaxhops = 3

Hop control and preventing sharing loops

When setting up multi-level schemes, you need to ensure that loops do not occur. Make sure that a uniquecccam node id is configured for each server so that OScam can cut off its own loops.

Diagnostics and solving typical problems

Problems with OScam can arise at different stages. It is important to be able to read logs and understand what each status means.

Reading the oscam log via webif and logfile

OScam logs are available through the web interface or in the file/var/log/oscam.log. Keep an eye onECM time and statuses to quickly identify the problem.

ECM time, statuses (found/not found/timeout)

ECM time shows the time spent processing the request. Statuses can indicate the presence or absence of a card. If the statusnot found, it may be related to an incorrectcaid/ident.

AU problems (key updates) and EMM

Key updates may not work if not configuredau inoscam.user. Make sure you have the correct settings for receiving EMM.

NAT, firewall, and port forwarding

If you are having trouble accessing the server, check the NAT settings and port forwarding on the router. Ensure that OScam is listening on the correct interface.
