After successful initialization of the baseline database, you can run samhain in 'check' mode by typing:
samhain -t check
To run samhain as a daemon, you can either use the command line option '-D', or set daemon mode in the configuration file with the option 'Daemon=yes'.
When testing samhain for the first time, you may want to use the command line option --foreground to run samhain in the foreground rather than as daemon. This allows to spot the reason for eventual problems much easier.
