daemonlogger - simple network logger and soft tap daemon
daemonlogger is a simple network packet logger and soft tap daemon. It is able
to log packets to file or mirror to another interface.
Show summary of options.
Show version of program.
Log <count> packets and exit.
Run as a daemon.
Load bpf filter from file.
Flush the pcap buffer for each packet.
Set group to <group id>.
Set user to <user name>.
Set interface to grab data from to <interface>.
Set log directory to <path>.
Generate <count> number of log files and exit.
Set ouput file prefix to <name>.
Disable logging, instead mirror traffic from -i <interface> to -o
Set PID filename to <pidfile>.
Set PID path to <path>.
Activate ringbuffer mode.
Read packets from <pcap file>
Automatically roll over the log file after <bytes>.
Set number of bytes per packet to capture to <snaplen>.
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.
Chroot daemonlogger to <chroot dir>
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
