beginner question on reshare

Answer to your first question - if you give one reshare to a peer then they can reshare this with all of their peers, but so long as you set your reshare level to 1 then the peers your friend reshares this to should not reshare this again, so long as they are not ignoring the reshare level within Oscam.

If you are using Oscam, you can use the CCcam protocol - in your oscam.conf you need to add something like this;

[cccam]
port                          = 12000
version                       = 2.2.1
reshare                       = 1
stealth                       = 1

Change 12000 port to whatever you prefer, and ensure that this port is forwarded on your router to your Oscam server.

For each peer you can then set up their user accounts something like the below

[account]
user                          = user
pwd                           = password
hostname                      = [your peer's ip address]
uniq                          = 3
keepalive                     = 1
group                         = 1
cccmaxhops                    = 2
cccreshare                    = 1
numusers                      = 1

You can then give your peer a cline

C: youripaddress.com 12000 user password

again change 12000 to whatever you set in the [cccam] part of oscam.conf

this account would give your peer your local plus one reshare plus your next two hop reshares.
