NAME

       daemonlogger - simple network logger and soft tap daemon

SYNOPSIS

       daemonlogger [Options]

DESCRIPTION

       daemonlogger  is  a  simple  network  packet logger and soft tap daemon. It is able to log
       packets to file or mirror to another interface.

OPTIONS

   --help
       Show summary of options.

   -v
       Show version of program.

   -c <count>
       Log <count> packets and exit.

   -d
       Run as a daemon.

   -f <bpf file>
       Load bpf filter from file.

   -F
       Flush the pcap buffer for each packet.

   -g <group id>
       Set group to <group id>.

   -u <user name>
       Set user to <user name>.

   -i <interface>
       Set interface to grab data from to <interface>.

   -l <path>
       Set log directory to <path>.

   -m <count>
       Generate <count> number of log files and exit.

   -n <name>
       Set output file prefix to <name>.

   -o <interface>
       Disable logging, instead mirror traffic from -i <interface> to -o <interface>.

   -p <pidfile>
       Set PID filename to <pidfile>.

   -P <path>
       Set PID path to <path>.

   -r
       Activate ringbuffer mode.

   -R <pcap file>
       Read packets from <pcap file>

   -s <bytes>
       Automatically roll over the log file after <bytes>.

   -S <snaplen>
       Set number of bytes per packet to capture to <snaplen>.

   -t <seconds>
       Rollover the log file on time intervals.  Append an 'm' to rollover on minute  boundaries,
       'h'  to rollover on hour boundaries and 'd' to rollover on day boundaries.  If no interval
       selector is used then the default rollover interval is in seconds.  For example,  "-t  60"
       rolls  the  log  file  over every 60 seconds and "-t 2h" rolls the log file over every two
       hours at the top of the hour.  In the case of minute/hour/day-based  rollovers,  the  will
       round  to  the next highest hour.  For example, if the program is told to rollover every 2
       hours and is started 38 minutes into the current hour it will add 2 to  the  current  hour
       and  rollover  as  scheduled at the top of the hour at <current hour> + 2.  If the program
       was started at 13:38 it would roll over the logfile at 15:00.

   -T <chroot dir>
       Chroot daemonlogger to <chroot dir>

   -z
       Select log file pruning behavior.  Omitting this switch results in the default mode  being
       used  where the oldest log file in the logging directory is pruned.  Setting the -z switch
       changes the behavior so that Daemonlogger will prune the  oldest  file  from  its  current
       instantiation and leave files from older runs in the same logging directory alone
