ProFTPD module mod_ident
ProFTPD module mod_ident
RFC1413 Identification Support
The mod_ident module is ProFTPD's module for performing
lookups of authenticated user IDs, as per
RFC 1413.
This module is contained in the mod_ident.c file for
ProFTPD 1.3.x, and is compiled by default. See the
installation section for more details.
The most current version of mod_ident can be found in the
ProFTPD source distribution:
http://www.proftpd.org/
Directives
Syntax: IdentLookups on|off
Default: IdentLookups on
Context: server config, <VirtualHost>, <Global>
Module: mod_ident
Compatibility: 1.3.2rc1
The IdentLookups directive enables or disables the module's lookup
of an "authenticated" user identity using RFC1413.
Normally, when a client initially connects to ProFTPD, the
mod_ident will attempt to use the ident protocol (RFC1413) to
identify the remote username. This behavior can be disabled via this directive:
IdentLookups off
Not that this lookup can cause delays (and reports of "slow logins")
when clients connect to ProFTPD.
The mod_ident module is compiled into proftpd by
default. To build a proftpd which does not include the
mod_ident module, use:
$ ./configure --disable-ident ...
Note that the mod_ident module can also be built as a shared
module, rather than be statically linked into proftpd:
$ ./configure --enable-dso --with-shared=mod_ident ...
Logging
The mod_ident module supports trace logging, via the module-specific log channels:
Thus for trace logging, to aid in debugging, you would use the following in
your proftpd.conf:
TraceLog /path/to/ftpd/trace.log
Trace ident:20
This trace logging can generate large files; it is intended for debugging use
only, and should be removed from any production configuration.
