NAME

mf2b - micro fail2ban

SYNOPSIS

mf2b [-fqv] [-c config-file ] [-l log-file ] [-p pid-file ] [-r chroot-dir ]

DESCRIPTION

mf2b acts as a replacement to the well-known fail2ban daemon, but with embedded systems in mind. Therefore it has been written in pure C and doesn't depend on external libraries to be present on the target. Despite the similar concept, it's not a drop-in replacement as configuration syntax aligns more with that of logrotate.

OPTIONS

-c config-file: Read configuration from config-file instead of the default /etc/mf2b.conf.
-f: Do not fork into background. Log output is then sent to stderr instead of syslog when daemonising.
-l log-file: Change log output to log-file instead of the default of stderr or syslog when -f has not been specified. The argument log-file may either be a path to a file log messages are to be appended to, stderr if log messages should go to standard error or syslog if log messages should be sent to the syslog daemon.
-q: Decrease log verbosity from the default of (as in syslog-terminology LOG_ERR down to LOG_CRIT or no logging at all, so (without any -v given before) this option may effectively be passed up to two times.
-p pid-file: Write daemon's process ID to pid-file. If multiple instances are started with the same pid-file specified, the file will contain the latest executed process' ID.
-r chroot-dir: Change root directory to chroot-dir prior to going into normal service. For this to work, mf2b has to be running with effective user ID 0.
-v: Increase log verbosity from the default of (as in syslog-terminology LOG_ERR up to LOG_WARNING, LOG_NOTICE, LOG_INFO, or LOG_DEBUG respectively, so (without any -q given before) this option may effectively be passed up to four times.

FILES

There certainly are, but of course this is subject to change. :)
