#### CONFIG - START

## OScam WebIf with SSL? [1=yes , 0=no]
OSssl="0"

## /path/to/oscam.conf?
OScfg="/var/etc/oscam.conf"

## Cards to monitor
CARD["1"]="mille"
CARD["2"]="sky"
CARD["3"]="skd"
CARD["4"]="skdhd"

## monitoring Error message (%CARDNAME% gets replaced by the script (its a placeholder!))
##  multible error messages possible, simple add for each an own array
OSerror["1"]="ERROR Phoenix_GetStatus: ioctl error in card detection for %CARDNAME%"
OSerror["2"]="%CARDNAME% .* Input/output error"

## OScam's Logfile?
OSlog="/var/log/oscam.log"

## reporting logfile for this script?
OStolog="/var/log/oscam.error"
