cccam cluster?

[rindler]

how could i set a cccam cluster?
it means: link more computers ( servers ) to process cccam calculation

Re: cccam cluster?

AFAIK only loadbalancing between cards is possible:
here is what is written in ccc*m.cfg

# load balancing between identical cards, list device names of card readers containing identical cards,
# optionally followed by a list of service id's which are to be excluded from loadbalancing
#
# LOADBALANCE : <device1> <device2> .. <devicen> { <exceptsid1>, <exceptsid2> .. , <exceptsidn> }
#
# multiple loadbalance groups can be configured, by adding multiple lines
# warning: restart is required, when loadbalance group config changes
#
#example 1: load balance requests for three identical cards
#
# LOADBALANCE : /dev/ttyS0 /dev/ttyS1 /dev/ttyS2
#
#example 2: load balance requests for two almost identical cards, sid 0df3 and 0de1 are only available
#on one of the cards, so requests for these sids shouldn't be loadbalanced
#
# LOADBALANCE : /dev/ttyS5 /dev/ttyS6 { 0df3,0de1 }

Re: cccam cluster?

hi, there is any emu, cccam or other that allow to create a cluster or loadbalacing/redudant?
Or the unique way is to manage a script for control and switching betwin two or more emu?
Of course in two separate hardware server

Loadbalancing is only to balance load between two or more cards servers, it's not like disk raid, i.e. when a disk is down the second one takes it's place.
You should "clone" a second server, keep it in standby and, when primary server fails, switch the backup on and swap cards (or card readers).

Re: cccam cluster?

so isn't possible to use two servers as a cccam cluster? ( use always both and when one goes down use only the other? )

Re: cccam cluster?

Yes, it is possible, but when one server goes down you have to modify some configuration files and swap cards (or card readers), of course.
There's nothing "automagic" and you must also have physical access to servers.

Re: cccam cluster?

could you please explain how to do this?

Re: cccam cluster?

If you normally use both, it means they are distributing the load (half users on one server, half of the cards on one server etc. etc.).
When one of the two servers goes down, the other must take the whole load, so you have to restart it with config files that take the whole load of users and cards on itself.
You can do it very fast with a simple bash script, but moving cards (or card readers) involves a physical access to the machines.
