is the Professional File Transfer Protocol (FTP) server daemon. The server
may be invoked by the Internet "super-server" inetd(8) each time a
connection to the FTP service is made, or alternatively it can be run as a
is run in standalone mode and it receives a SIGHUP then it will reread its
configuration file. When run in standalone mode without the
option, the main
daemon writes its process ID to
to make it easy to know which process to SIGHUP.
Display a short usage description, including all available options.
Runs the proftpd process in standalone mode (must be configured as such in
the configuration file), but does not background the process or
disassociate it from the controlling tty. Additionally, all output (log
or debug messages) are sent to stderr, rather than the syslog mechanism.
Most often used with the -d option for debugging.
Quiet mode; don't send logging information to standard error when running
with the -n option.
Displays the version number of ProFTPD to stdout.
Sets a configuration parameter which can be used <IfDefine>...</IfDefine>
sections in the configuration files to conditionally skip or process
Sets proftpd's internal debug level (normally 0). The debuglevel
should be an integer value from 0 to 10, with higher numbers producing more
debug output. Normally, debug messages are sent to syslog using the
DEBUG facility, however if the -n option is used, all such
output is sent to stderr.
Specifies an alternate config-file to be parsed at startup, rather
than the default configuration file. The default configuration file is
Disables address/port collision checking.
Displays various compile-time settings and exits.
Specifies an IP address for the host machine, avoiding an DNS lookup of the hostname
Read the configuration file, report any syntax errors, and exit.
Disables (0) or enables (1) the default persistent password support, which
is determined at configure time for each platform. This option only
affects the default support, it can still be overridden at run-time with
the PersistentPasswd directive.
Lists all modules compiled into proftpd.
Support IPv4 functionality only, regardless of whether the
--enable-ipv6 configure option was used.
Support IPv6 connections and lookup of IPv6 addresses for server DNS names.
This is enabled by default, if the --enable-ipv6 configure option is
