You can add this to oscam.conf, this will setup the log file.
Code
# logging
#pidfile = /var/run/oscam.pid
logfile = /var/log/oscam.log
usrfile = /var/log/oscamuser.log
cwlogdir = /var/log/cw.log
maxlogsize = 1000
You can access the oscam.log by navigating to /var/log or by using the below command in putty.
JSC card gets one update then its activated for the year. Sly gets update every two months and the oscam configs you have will do this. Tring needs an update on the first of every month and oscam does not do this, you need a conax cam or a combination of mgcamd+oscam.
