CCcam and OScam setup: server guide 2026

If you are reading this, you have already gone through the first circle of hell — installed the software, connected the receiver, and... nothing. A black screen, constant freezes, or a connection error that explains nothing. CCcam and OScam server setup: configuration, ports, and troubleshooting — this is what we will cover here, with real paths to files, working examples, and explanations of what each part is responsible for. No fluff.

CCcam vs OScam: which protocol to choose for your task

Both solutions do the same thing — distribute decryption keys to receivers. But they are fundamentally different in structure, and the choice affects how painful it will be to live on.

Key differences between CCcam and OScam

CCcam is a closed protocol specifically developed for Dreambox. You install it, enter the C-line, and most of the time it just works. No unnecessary settings. But this simplicity turns into a downside: one protocol, limited flexibility, no proper web interface for diagnostics.

OScam is open source, originally written as an alternative. It supports multiple protocols simultaneously: cccam, newcamd, gbox, camd35. It has built-in web monitoring, detailed logs, flexible management of readers and users. More complex at the start, but significantly more powerful in real-world use.

When OScam is preferable

If you have a Linux server and several clients — OScam is definitely the way to go. Distributing one share simultaneously via cccam and newcamd, restricting specific users by time or channels, viewing ECM time in real-time — all of this is available out of the box.

CCcam makes sense if you have one receiver like the old Dreambox DM800 and just need to connect to the server via C-line. For a server servicing multiple clients, OScam wins on all parameters.

Compatibility with different receivers and Enigma2

Enigma2 images (OpenPLi, OpenATV, OpenVIX) support both options through plugins. CCcam is installed as a separate plugin and runs as a daemon. OScam comes either through an ipk package or is compiled from source — on newer images, I recommend the latter, as versions in repositories often lag behind.

On Dreambox with the original DreamOS, working with CCcam is easier. On VU+, Gigablue, and other hardware with OpenPLi — OScam causes fewer problems during image updates.

Installation and structure of configuration files

Half of the problems start with the person editing the wrong file. The paths depend on the image and distribution, and this can really confuse.

Paths to files: /var/etc/CCcam.cfg and /etc/tuxbox/config/oscam/

For CCcam, the main configuration file is/var/etc/CCcam.cfg. On some images, especially older Gemini, it is located in/usr/keys/CCcam.cfg. If you don't know where — execute:

find / -name "CCcam.cfg" 2>/dev/null

For OScam, the config directory is typically in/etc/tuxbox/config/oscam/ or/etc/oscam/ — it depends on how the binary was built. Check the line--config-dir when starting:

ps | grep oscam

Main OScam files: oscam.conf, oscam.server, oscam.user

oscam.conf — global settings: logging, protocol ports, web interface parameters. This is the first file that is edited during initial setup.

oscam.server — description of readers. Each block[reader] — is one source: a physical card in a card reader or a remote server via newcamd/cccam. This is where the server addresses, ports, and logins are specified.

oscam.user — client accounts. Each block[account] — one user with a password, CAID restrictions, groups, and time. Here, it is also specified which readers the client has access to via the parametergroup.

There is alsooscam.services for filtering by specific services andoscam.srvid for mapping CAID to channel names — but this is already fine-tuning.

Access rights and daemon restart

OScam must read its configs, which means the permissions on the directory and files must correspond to the user under which the daemon is running. A typical mistake is copying the file from root, while OScam starts under a separate user.

chown -R oscam:oscam /etc/oscam/

Restart via systemd:

systemctl restart oscam

Or via init.d on Enigma2:

/etc/init.d/oscam restart

After editing the configs through the OScam web interface, the reader restarts automatically — but global changes in oscam.conf require a full restart.

Share configuration: C-line, N-line, and port parameters

This is where the essence begins. Incorrect syntax or an incorrect port — and the receiver simply will not connect, without providing any clear error message.

C-line syntax: C: host port username password

The C-line for CCcam looks like this:

C: hostname.example.com 12000 myuser mypassword

No extra characters, no quotes. The case of the login and password is important — this is a regular cause of errors when copying from the provider's email.

N-line for newcamd is a bit more complex:

N: hostname.example.com 16000 myuser mypassword 01 02 03 04 05 06 07 08 09 10 11 12 13 14

The last 14 bytes are the DES key. If the provider did not specify it, the standard one is used:01 02 03 04 05 06 07 08 09 10 11 12 13 14.

Standard ports (12000 for cccam, 16000 for newcamd)

CCcam listens on port by default12000. Newcamd —16000. These are defaults, but a specific provider or server may use any other port — check the connection data.

In oscam.conf, protocol ports are specified in the corresponding sections:

[cccam]

Format16000@1234:000000 means: port 16000, CAID 0x1234, provider 0x000000. If you want to accept all CAIDs on this port, just writeport = 16000.

Configuration of the newcamd protocol in oscam.server

Reader block for connecting to an external server via newcamd:

[reader]

Parametercaid here is a hint to OScam about which ECM requests to send to this reader. Without it, OScam will try all readers in turn, which slows down the response.

Share limit: uphops, downhops, cccmaxhops

Parametercccmaxhops in CCcam.cfg determines from which hop levels to accept cards. A value of 1 means only direct server cards, without reselling. I recommend setting it to a maximum of 1-2.

In OScam, for the cccam-reader, the same applies tocccreshare andcccreshare_sourceid. Settingcccreshare = 0 means: accepted cards are not shared further. This reduces the load and prevents your server from accidentally becoming a transit node.

[reader]

Diagnostics and troubleshooting common errors

Configuring CCcam and OScam server: configuration, ports, and troubleshooting — this is 50% diagnostics. Without understanding the logs, you can sit and restart the daemon for hours, changing parameters at random.

Reading logs: oscam.log and web interface on port 8888

Enable logging in oscam.conf:

[global]

The web interface is enabled there as well:

[webif]

After that, open a browser athttp://ip-сервера:8888 and see in real time: status of readers, ECM time, active clients, latest requests. This is hundreds of times more informative than blindly reading a text log.

Error "card not found" and empty ECM response

The most common situation: the receiver is connected, but there is no decoding. The log shows something likeno card found for CAID 0x1234.

First — check the CAID. Different packages use different CAIDs, and if the reader has an incorrect one specified — it simply will not process requests. In the web interface under the Readers tab, you can see which CAIDs each reader actually sees.

Second — provid. Some providers use multiple provider IDs within one CAID. If the reader works only with one provid, and the channel requires another — there will be no response. Check throughoscam.srvid and the logs of ECM requests.

Third — priority conflict with multiple readers having overlapping CAIDs. OScam polls them in the order specified by the parametergroup and weightlb_weight. If the first reader does not respond for a long time, OScam waits for a timeout before moving on to the next one — hence the delays and freezes.

Problems with server time (NTP) and desynchronization

This quietly and unnoticed kills the connection. Conditional access protocols (especially Viaccess, Irdeto) are sensitive to time. A desynchronization of more than 3-5 seconds between the server and the receiver — and ECM requests start to be rejected.

Check the synchronization:

ntpq -p

If NTP is not configured — configure it. On the Enigma2 receiver, the time is synchronized via the NTP server in the system settings. On a Linux server, usechrony orntpd. Without this, no manipulations with configs will help.

High ECM time and picture freezes

ECM time — the time from the key request to receiving a response. The norm is up to 500-600 ms. Anything above 1000 ms causes noticeable freezes. Above 2000 ms — constant artifacts and loss of picture.

Causes of high ECM time: physically distant server (network delay), overloaded reader on the provider's side, too many hops in the chain (each adds 100-300 ms), or a slow card reader with a physical card.

In the OScam web interface, the "Status" tab shows ECM time for each request. If you see that the time is normal for some channels and high for others — they are likely served by different readers with different pings.

Server security and connection stability

Most instructions end with "the setup worked." But an open web interface without a password on a public IP and an account without restrictions — is an invitation for unauthorized clients and a load on your server.

Closing the web interface and changing default ports

Never leave port 8888 open on the external interface without a password. At a minimum — sethttpuser andhttppwd. Better — restrict access to specific IPs viahttpallowed:

[webif]

Change the default cccam port from 12000 to a non-standard one — this is basic protection against automatic scanners. Port 12000 is constantly scanned.

If the server is behind NAT — do not forward the web interface port outside at all. Connect to it via SSH tunnel if necessary.

Client restrictions via oscam.user (group, monlevel)

Assign the minimum necessary rights to each client in oscam.user:

[account]

monlevel = 0 — the client does not see web monitoring.maxconnections = 1 — cannot connect from two devices simultaneously.expdate — automatic disconnection by date. These three parameters are mandatory for any normal configuration.

Parametergroup this should match withgroup in the required blocks of readers in oscam.server — this is the access control mechanism. A client from group 1 sees only readers withgroup = 1.

Protection against overload: maxecmsend and AU settings

The parametermaxecmsend in oscam.user limits the number of ECM requests per second from a single client. A normal receiver makes 1-2 requests per second. If someone sends 20+ — this is either a faulty client or intentional load.

AU (Auto Update) — the mechanism for automatic key updates from the physical card. In oscam.server for the reader with the card:

[reader]

au = 1 enables automatic updates. After restarting, the reader sometimes hangs on card initialization — the parameterdetect = CD and increasingcardmhz to the actual value for your card reader helps.

For servers with a dynamic IP from the provider — set up DynDNS and use the hostname instead of the IP in the clients' C-line. Otherwise, with each IP change, you will have to send new connection data to all clients.

Configuring the CCcam and OScam server: configuration, ports, and troubleshooting is an iterative process. The first launch is rarely clean. But if you understand what to read in the logs and what each line of the config means, you will find the problem in minutes, not hours. The foundation is the correct paths to files, correct CAIDs, synchronized time, and a closed web interface. Everything else is built on this foundation.
