Re: Differences between cccam-versions as server?

Here some posts

... Now I recompiled a version so I could trigger the backdoor myself, and TADA, ...

It would be nice to know how this guy could "recompile" ...
It surely means he has the sources, but if he has the sources he knows EVERYTHING about ccc*am.
Sounds like a story ...

Re: Differences between cccam-versions as server?

The 256 trick will not work on any version of CCCam over 2.1.3

At least 2.0.11, I know.

Re: Differences between cccam-versions as server?

256 trick, ok, one reason. It's a simple cheat to hide the original card position.
But are there other performance differences?

Re: Differences between cccam-versions as server?

... are there other performance differences?

i compare cpu and mem % for cccam 2.0.10, 2.0.11, 2.1.4, 2.2.1 and 2.3.0
monitored by top (the gnu process monitoring tool)

i posted the facts here:

interesting comments in the post ...

Re: Differences between cccam-versions as server?

i compare cpu and mem % for cccam ...

OK, but did you compare as server or as client?
Or is there no difference when looking into your results?

[aplok]

Re: Differences between cccam-versions as server?

it was as a client

for further details, i have to dive into the post to remember more precisely ...

i'll tell you later ...

Re: Differences between cccam-versions as server?

... a trick or an illusion ? :

even if the hop counter is reset to 0,

this does not stop the ecm time response ... and further freezing ...

...trick or an illusion , I think that the result is the same...
They used this in order to cheat and present as local cards , the cards that they were receiving as clients .
They don't care about ecm time response as they only want to show that have local cards and how to collect more and more.

Re: Differences between cccam-versions as server?

I've read somewhere (don't know exactly when or where) that there's a different behavior of the cccam versions as server when more than one user tries to connect with the same cline (like it often happens with bigger free-servers).
Does anyone know details about that?

Re: Differences between cccam-versions as server?

hi

if the server is on linux pc, you can monitor connections:

- to list established connections:

lsof -i |grep ESTABLISHED


- to list established connections on CCcam server, running the executable cccam, on port 31234 :

lsof -i |grep ESTABLISHED |grep cccam |grep 31234


- to list badguy ip with multiple connections to 31234 port, on cccam server:

lsof -i |
perl -ne 'print "$1\n" if/^cccam.*TCP .*->([^ ]*) .ESTABLISHED/' |
sort -u |
perl -ne 'BEGIN{$p=0}{/([^:]*)/; print "$1\n" if($p eq $1); $p=$1}'


- to ban those badguy :

# activate the iptables black list (badguy):
iptables -A INPUT -m recent --name badguy --rcheck -j DROP

# identify badguys, and add their ip into iptables black list:
lsof -i |
perl -ne 'print "$1\n" if/^cccam.*TCP .*->([^ ]*) .ESTABLISHED/' |
sort -u |
perl -ne 'BEGIN{$p=0}{/([^:]*)/; print "$1\n" if($p eq $1); $p=$1}' >> /proc/net/xt_recent/badguy


- to purge iptables black list:

echo > /proc/net/xt_recent/badguy

Hi, Can you help me as i'm new to all this,i'm buying a skybox and dont't know much about setting it all up apart from looking on the net.I understand i have to get a cline from a server? but I am in the dark here?...where do i get these,do i have to pay?Hope you can help.Thanks.

Well said aplok !
I think people talking about backdoors don't know much of linux internals ... we have some powerful commands that show perfectly what's going on inside our receivers.

Re: Differences between cccam-versions as server?

OK, I've found the answer which I was looking for in post #24. It was written on a site which is a known traitor of satlovers clines, so I have no problem to just copy and paste the articel:

"CCcam: why good clines show 0 shares?

To understand why this happens, we need a little background on the matter. As we know, a cline has the following syntax:

C: <hostname> <port> <username> <password>

Basically, it tells our box to connect to hostname : port using username / password as credentials. On the other side, the box acting as a server is listening for new connections. In normal circumstances, when a new client connection is received, the server checks if the received username/password is found in the local config file as a fline, and grants the connection.
But what happens when a new client logins and there’s already a connection present for the given username?

This scenario is quite frequent with the free clines found on internet because eventually many clients will use the same cline.

In this situation, the older CCcam versions up to v2.0.11 used a strategy consisting in allowing only one connection per user, keeping the last login and closing the previous connection. Since multiple logins are assumed to happen due to network issues, for instance when a new ip is assigned by our isp, this behavior grants a fast reconnection.
What happens when two or more boxes use the same cline?

Let’s says we have a box labeled Client1 which connects to a box Server1. Since we are the first client, we can login without further problems. Now, if a new box Client2 establishes a connection using the very same cline, then Server1 will accept this new client and discard our connection. But then Client1 will reconnect to the server and, as you should have figured by now, Server1 will drop Client2. Of course Client2 won’t abandon but will reconnect after a short timeout and thus starting a cycle that prevents both clients from using the cline.

To mitigate this issue, starting from the version 2.1.0, the developers of CCcam opted for a different strategy. From now on, multiple logins are not allowed and therefore only the first client will be kept. Any further connection attempts using the same cline are ignored. This prevents the cycle discussed earlier but the downside happens when a legitimate client loose his connection and wants to reconnect. In this case, he will be rejected and will have to wait until the previous connection is marked as dead, which usually happens after a few minutes.

In conclusion, the 0 card issue happens when multiple clients try to connect to a cccam server v2.0.11 or below with the same cline. Luckily, the cccam version is always shown in the details of the [...] Edit: cccam-webinterface."

Re: Differences between cccam-versions as server?

@ Satphoenix

that answers a question that i am making myself a longtime: "what happens when 2, 3, 4, 5... persons connect to a server using the same line?"

So, below 2.1.0 cccam version (2.0.11) "everyone" is able to connect with the same line, right?
