Hello For a system that constantly (24 hours 7 days per week) receives data via DVB-S, is it necessary to have szap always running in the background? Or is it sufficient to once start szap at boot time as follows: szap -c /etc/channels.conf -n 1 -x When doing it this way, what happens if the LOCK gets lost for some reason, say bad signal quality? Would it not be better to have szap run in daemon mode and check the status and always do some logging to syslogd? Holger (Kiehl) --
