CCcam sharing: server and client setup in 2026

If you have reached this article, it means you already understand the basics: there is a access card, there is a receiver, and somewhere between them you need to set up cccam sharing so that everything works without freezes and drops. This article is not for those looking for a "ready-made line to insert and watch". Here we analyze each field of the config, explain what happens at the protocol level, and honestly discuss the pitfalls.

What is CCcam sharing and how does the protocol work

The principle of card sharing: ECM and DCW

The satellite channel is encrypted by conditional access systems — Viaccess, Nagravision, Irdeto, and others. The receiver, receiving the stream, extracts the so-called ECM packet (Entitlement Control Message) from it. This is an encrypted request: "give me the key to decode this content." Without the correct response — a black screen.

The response is the DCW (Descrambling Control Word), a 16-byte key that changes every few seconds (usually 10 seconds). The access card inserted into the card reader can decrypt the ECM and return the current DCW. The task of cccam sharing is to transmit this response to a remote receiver without a physical card.

The role of the server and client in the scheme

The server is a machine (or receiver) with a real card in the card reader. It receives ECM from clients, decrypts it through the card, and returns the DCW. The client is your receiver, which does not have a card. It connects to the server via TCP, sends ECM, receives DCW, and decodes the channel.

It is critically important to understand the delay. From the moment a new ECM arrives to receiving the DCW, less than 500 ms should pass for the client — otherwise, the decoder does not keep up and a characteristic freeze of 1-2 seconds occurs, especially noticeable when switching channels.

Port 12000 and CCcam protocol encryption

CCcam by default operates on TCP port 12000. When connecting, a handshake occurs: the client and server exchange random 16-byte values, based on which a SHA1 hash is generated for encrypting the traffic. All subsequent communication goes through this encrypted channel.

The handshake also depends on the system time. A clock discrepancy of more than 60 seconds between the client and server will guaranteed break the connection — the receiver simply will not pass authentication. Therefore, a configured NTP client is not an option, but a mandatory condition. On Enigma2 receivers, this is done through `/etc/init.d/ntpd` or the corresponding menu section.

How CCcam differs from OScam and MGcamd

CCcam is a closed binary without source code, development ceased around 2012-2013. MGcamd is also closed, works on a similar principle, but uses its own newcamd protocol instead of CCcam. OScam is open-source, actively supported, supports both protocols, and can work as both a server and a client simultaneously.

In practice: CCcam is easier to set up from scratch, but OScam wins in stability under load and provides detailed statistics for each reader in real time.

Installation and configuration of CCcam server

File structure: /var/etc/CCcam.cfg

The main config is `/var/etc/CCcam.cfg`. On some firmware (especially older Gemini and OpenPLi), the path is different: `/etc/CCcam.cfg`. The binary is most often located in `/usr/bin/CCcam` or `/var/bin/CCcam`. If you edit the file and the settings do not apply — first check what path your firmware actually uses.

Additionally, CCcam reads `CCcam.providers` (list of providers for filtering) and `CCcam.channelinfo` (mapping CAID/SID with channel names). These files are optional but useful for debugging. Access rights on the config: `chmod 644 /var/etc/CCcam.cfg`.

Basic server config and parameters

The minimum working config for the server looks like this:

`MAX HOPS` determines how deeply your server will pass cards from other sources. `RESHARE : 1` allows reshare — without this, connected clients will not see the cards of your upstream servers.

Line sharing: F-line for clients

F-line (Forwarding line) is created on the server for each client who is granted access:

F: myuser mypassword 1 0 0

Fields in order: username, password, uphops (how many levels up the client sees), downhops (limit on reshare by the client), sharelimit (0 = no limits). `uphops : 1` means that the client only sees cards directly connected to your server — not the cards of your upstream partners. This is a reasonable default setting.

Each F-line corresponds to one C-line on the client side. This is a pair. Created an F-line on the server — you send the client a C-line with the same login and password.

Connecting the card reader through reader/newcamd

If a physical card reader is connected to the server, it is described through the DEVICE line. For a standard USB or built-in reader on an Enigma2 box, it is sufficient that CCcam finds the reader automatically. For a newcamd server (a separate device with a card) you add:

N: hostname 10000 username password 01 02 03 04 05 06 07 08 09 10 11 12 13 14

The last 14 bytes are the DES key for newcamd. This format is used when the card itself is on another machine that provides DCW via the newcamd protocol, and your CCcam server acts as an aggregator.

Configuring the CCcam client and C-line

C-line syntax: host port user pass

C-line (Connection line) is a connection string on the client side. It looks like this:

C: myserver.ddns.net 12000 myuser mypassword no { 0:0:1 }

Let's break down the fields. `myserver.ddns.net` — host or IP of the server. `12000` — port. Next are the login and password from the server's F-line. `no` — whether NODEID is needed (usually no). The curly braces `{ 0:0:1 }` — this is the share limit in the format `{ minutes:seconds:reshare }`. `0:0:1` means "no time limits, reshare allowed."

If you set `{ 0:0:0 }` — the client will not reissue the received cards further. For a regular home receiver, this is normal and even preferable.

Where to write the C-line in CCcam.cfg

The C-line is written in the same file `/var/etc/CCcam.cfg` on the client receiver. No separate files — everything in one config. After changing the file, a daemon restart is needed: `killall -9 CCcam&& sleep 2&& /usr/bin/CCcam&` or through the firmware script `/etc/init.d/softcam restart`.

One of the common mistakes is Cyrillic or invisible characters in the file after editing with Windows editors. The file must be in UTF-8 or ASCII without BOM. Edit via `nano` over SSH — it’s more reliable.

Checking the status through the web interface (port 16001)

CCcam raises a built-in HTTP server on port 16001. Open in your browser `http://192.168.1.100:16001/` (IP of your receiver) and see a live picture: which cards are available, the status of each C-line, the number of active clients, the time of the last ECM request.

The status line shows: `ON` (connection active) or `OFF` (no connection), the number of hops to the card, the number of available entitlements. If the line shows `ON` but hops = 0 and entitlements = 0 — the card exists, but is empty or not valid for the requested package.

Multiple lines and priorities

You can add several C-lines to the config. CCcam will use them in parallel and choose the best response by speed. But there is a nuance: if several C-lines point to the same physical card (through different resellers), you create a load on one source, rather than getting redundancy. During prime time, this leads to freezes for all clients simultaneously.

Real redundancy means C-lines to servers with physically different cards, preferably at different satellite positions or from different operators.

Transition from CCcam to OScam: pros and cons

Why OScam is more stable and actively developed

CCcam was last updated more than ten years ago. During this time, new versions of encryption systems have appeared, algorithms have changed for a number of operators, and the CCcam binary itself has not received any patches. OScam, on the other hand, has an active repository, regular builds, and support for current CAIDs.

Under load — say, 20+ simultaneous clients — OScam is noticeably more stable. There is precise statistics for each reader: average ECM time, number of responses in the last hour, cache hit percentage. CCcam does not provide this.

Converting C-line to oscam.server format

Let’s take a standard C-line:

C: myserver.ddns.net 12000 myuser mypassword no { 0:0:1 }

In OScam, this turns into a `[reader]` section in the `/etc/oscam/oscam.server` file:

`group = 1` links the reader to the user group — this needs to be specified in `oscam.user` for clients as well. `cccversion` should be specified explicitly to avoid compatibility issues with some servers.

[reader] sections and cccam protocol in OScam

For OScam to accept connections from CCcam clients (as a server), a section is needed in `oscam.conf`:

`stealth = 1` makes the OScam server less noticeable for fingerprinting — it disguises itself as the original CCcam server. Useful for compatibility with some clients. The minimal `oscam.conf` with this section + correct readers in `oscam.server` is all you need for a working server.

When CCcam is still justified

Honestly, rarely. The only real case is an old receiver with firmware that does not support OScam, or a situation where you need to set up sharing in 10 minutes without studying OScam configs. For a one-time test or temporary solution, CCcam is quite a workable option.

For a constantly running server — switch to OScam. It’s not more complicated, but it’s more stable and clearer in diagnostics.

Diagnostics of typical connection problems

Line OFF: checking ports and firewall

The first step is banal telnet. From any machine on the network:

telnet myserver.ddns.net 12000

If the connection did not establish — the problem is in the network, not in CCcam. Check iptables on the server: `iptables -L -n | grep 12000`. If there is no rule — add: `iptables -A INPUT -p tcp --dport 12000 -j ACCEPT`. On the router — check port forwarding to the server's IP.

If telnet connects but the line in CCcam is still OFF, the problem is with authentication. The login/password in the client's C-line must exactly match the server's F-line, including case sensitivity.

Black screen with share present (freeze/zapping)

Line ON, entitlements are present, but the channel is not working or there are constant freezes — this is already ECM timing. Open the web interface on port 16001 or the OScam log, and check the response time for ECM requests. More than 400-500 ms will cause freezes. More than 800 ms will guarantee artifacts when switching channels.

Freeze when zapping (switching channels) and normal operation on one channel — a classic sign of high hops. Each extra hop adds delay. With hops ≥ 3 on a loaded server, problems are almost inevitable.

ECM timeout errors and high hops

In the CCcam log `/tmp/CCcam.log`, look for lines `ECM timeout` or `no card found`. The first means the server is responding too slowly. The second means the card is either invalid for this package or simply does not exist.

The parameter `RECV TIMEOUT : 2000` in the config sets the maximum waiting time for a response in milliseconds. It is not advisable to reduce it below 1500 ms — with an unstable network, you will receive false timeouts. Increasing it above 3000 ms also makes no sense — the receiver still won't be able to apply the DCW in time.

Dynamic IP and DDNS

A gray (dynamic) IP from the provider means that your public address changes with each reconnection. The problem is that the C-line is configured with a specific address or hostname. The solution is a DDNS client on the router (DynDNS, No-IP, afraid.org) or your own VPS with a public IP as an intermediary node.

Even worse is double NAT. This is when your router is behind the provider's router (a typical situation with CGNAT). In this case, port forwarding 12000 on your router does not yield results — traffic does not reach due to the provider's NAT. The only solution is a VPS with a public IP and a tunnel (for example, through wireguard or SSH tunnel) between the VPS and the home server.

How to choose a line source: criteria without names

Stability and uptime of the connection

A good source for cccam sharing should maintain uptime above 99% per month. Checking this before payment is difficult, but you can request a test line for 24-48 hours and monitor it through the CCcam web interface or OScam statistics. If there were more than 2-3 disconnections during the test period, look for another source.

Disconnections during prime time (evening from 19:00 to 23:00) — the worst sign. This is when the load is maximum, and weak servers fail.

ECM response time and server locality

ECM time is the main technical indicator of line quality. A normal indicator: 100-250 ms. Good: up to 100 ms. Anything above 400 ms is a problematic source.

Physical distance matters. A server in your country or neighboring one usually gives a delay of 20-50 ms at the network level. A server in another region — already 100-150 ms. Plus processing time at each hop. It easily exceeds 500 ms with hops ≥ 2 and a remote server.

Signs of resold and unstable lines

A resold line is when too many clients are connected to one card. Signs: freeze specifically during evening hours, periodic disconnections, ECM time jumps from 80 ms to 900 ms. In OScam statistics, this is visible as a high `queue` — a queue of unprocessed ECM requests.

Another sign is too cheap a price without a trial period. A normal provider offers at least a 24-hour test. If they refuse a test — it's a reason to be cautious.

Legal risks and legal scenarios

It must be said directly. Card sharing for your legally purchased subscription within a household is a gray area in many countries. Some operators prohibit this in their terms of service, but there is no crime. A completely different story is the sale or distribution of access to someone else's subscriptions. This is already a violation of copyright and potential criminal liability in many jurisdictions.

Technically, CCcam does not distinguish between "own" and "foreign" access. Legal risks are entirely on the user. This article describes the technology; what to do with it and in what legal context — your choice and your responsibility.
