Introduction: Continuous growing of VPS Server, mixing with several emu on cacheex exchange and negligence to properly configure, have caused a huge proliferation of harmful ECM (CW Fake = vision interruption from 3 to 10 seconds) that can compromise also good working on server “ad-hoc”.

The purpose of this guide it's giving a correctly configuration line for OSCam (use higher versions of 9700) and exactly: activate a checking on any fake CW to improve stability on server and client.

In order that we can “reach” optimal condition this illustrated concept (as result after several tests) should be extended on all network topology for cache exchange (except for nodes that doesn't exchange with any other).

On this guide we see also how to cut out fake CW on exchange cache with MultiCS.

3) Appendix ”cacheex_cw_check”: On cache exchange it's important use OScam higher versions of 9700 and understand all activity performed by cacheex_cw_check, visible at [cache] section of oscam.conf file for only "Big Server VPS OScam" (if you get references to line guide reported on this document): result:

From this, we conclude that <Numbers_of_equal_CW> variable should be modified based on cache size reached exchanging cache with one or more server. To calculating cache size, disable [cache] section putting # character in front on every row:

oscam.conf restart OSCam and wait for traffic exchanging with your servers. After all, connect on Oscam Web Page and follow these steps:

cacheex_cw_check = <CAID>:0: <Numbers_of _equal_ CW>

will be accepted CW for specified <CAID> (example: 0919, 09cd, 093b, 1805, 0500) only if are counting at least <Numbers_of_equal_CW> equal

#[cache] #delay = 10 #max_time = 9 #max_hit_time = 9 #wait_time = 0:50:300,0100@000000:50:500,0500@000000:50:500,0919 @000000:50:400,093B@000000:50:300,09CD@000000:50:230,09C4@000000:50:400,098C@000000:50:400,1803@000000 :50:450,1804@000000:50:450,1805@000000:50:450,183D@000000:50:350 #csp_allow_request = 0 #cacheex_cw_check = 0:0:40,09CD:0:50,1803:0:50,1804 :0:50,1805:0:50,183D:0:50 #cwcycle_check_enable = 1 #cwcycle_check_caid = 0100,0500,0919,093B,09CD,09C4 ,098C,1803,1804,1805,183D #cwcycle_maxlist = 4000 #cwcycle_dropold = 1 #cwcycle_onbad = 2 #cwcycle_sensitive = 3 #cwcycle_allowbadfromffb = 1 #cwcycle_usecwcfromce = 1

Obtained the amount of cache size, remove this character # inserted previously on [cache] section and proceed properly setting parameter cacheex_cw_check taking a look on this table:

Cache Size (ALL) <Numbers_of_equal_CW>

= 0 ÷ 200 cacheex_cw_check = 0:0:10,09CD:0:15,1803:0:15,1804: 0:15,1805:0:15,183D:0:15



> 600 cacheex_cw_check = 0:0:40,09CD:0:50,1803:0:50,1804: 0:50,1805:0:50,183D:0:50

You get an optimale value for <Numbers_of_equal_CW> doing various tests and looking if changing that parameter will be reduce/canceled freeze (from 6 to 10 sec) during watching TV, therefore don't consider a “rule” value reported on table above but use as starting point to make your cacheex_cw_check optimal settings. Emerge that increasing cache size (ALL) you should increasing also variable <Numbers_of_equal_CW> so rejecting (eventually) received fake CW. Final result it's using local and provide on cache exchange topology only valid CW (OK) breaking down any other fake CW growing inside on the same newtork topology.

Note for calculating cache size: For calculate cache size received from a single Server, disable all server not interested and leave only Server to calculate. To calculate cache size (ALL) received from all Servers, enable all interested servers.

It's recommended to calculate cache size on particularly hours (night, week-end, or in special events) so we get a peak value and make our rule related on value reported.

4) Appendix OScam <-> Multics CacheEx:

To avoid growing of fake CW, on cache exchange between OScam and Multics, it's important always update your cam to last available release, as now:

Cam Release

OScam > 9700 Multics > r81

On the last release of Multics (r81) according to various tests made, seems to have solved problem on managing CacheEx exchange with OScam. If you use updated Multics, it's also recommended to refer to this link to get an updated list for fake CW (BAD):

www.multics.info/threads/bad-dcw-without-la-problems.35807 and on [cache] section of Multics putting as below: and on profiles 0919, 093b, 09cd it's recommended to add these new parameters included on Multics r81:
