1.1 OIDENTD - Ident Daemon

OPT_OIDENTD provides an Ident Daemon as specified in RFC 1413. Ident (former AUTH) is a service that delivers user data to other systems. Some E-Mail, News and IRC Servers use this service to check the identity of a user before allowing access. Ident uses TCP port 113. oidentd is used in particular.

Disclaimer: The author neither makes any guarantees for the proper function of OPT_OIDENTD, nor is he liable for any damage (i.e. data loss) caused by the use of OPT_OIDENTD.


1.1.1 Configuration Of OPT_OIDENTD

Configuration is done by adapting the file path/fli4l-3.10.5/<config>/oidentd.txt to your needs. Following is the description of the relevant variables:

OPT_OIDENTD

Default: OPT_OIDENTD='no'

The setting 'no' deactivates OPT_OIDENTD completely. No changes are made to the fli4l boot medium resp. to the archive opt.img. No other parts of the installation will be changed by OPT_OIDENTD.
To activate OPT_OIDENTD set the variable OPT_OIDENTD to 'yes'.


Important: For proper operation of oidentd it is essential to open INPUT port 113 TCP! As of version 2.1.12 the port is opened automatically!

OIDENTD_FORWARD

Default: OIDENTD_FORWARD='no'

OIDENTD_FORWARD sets if oidentd ident queries will be forwarded to the clients behind fli4l or will be answered from the database on fli4l. In the default setting queries will not be forwarded.

OIDENTD_DEFAULT

Default: OIDENTD_DEFAULT='unkown'

If neither the internal database nor forward (if activated) returns a valid answer oidentd will send the content of OIDENTD_DEFAULT as an answer.

OIDENTD_HOST_N

Default: OIDENTD_HOST_N='0'

OIDENTD_HOST_N sets the number of entries in the local database. For each entry the following OIDENTD_HOST_x_... variables have to be created. The index x has to be incremented up to the total number of entries.

OIDENTD_HOST_x_IP

By OIDENTD_HOST_x_IP the client resp. the subnet is specified for which an entry should be generated. The hostname (DNS name) as well as the IP address or the subnet may be specified.

Example:

OIDENTD_HOST_x_IP='192.168.6.1'
OIDENTD_HOST_x_IP='192.168.6.0/255.255.255.0'
OIDENTD_HOST_x_IP='192.168.6.0/24'
OIDENTD_HOST_x_IP='client.lan.fli4l'
OIDENTD_HOST_x_IP='@client'

OIDENTD_HOST_x_USERNAME

The content of OIDENTD_HOST_x_USERNAME is the answer sent by oidentd. This may be a user name, real name, an E-Mail address or something else. There are no blanks or spaces allowed. Please replace those by an underscore _ .

OIDENTD_HOST_x_SYSTEM

The answer to an ident request contains not only the user name (OIDENTD_HOST_x_USERNAME), but also the operating system in use. The corresponding acronyms are described in RFC 1340. Opt_oidentd only returns a limited selection: DOS, ELF, MACOS, MSDOS, OS/2, PC-DOS, SCO-XENIX/386, SUN, UNIX, UNIX-BSD, UNIX-PC, UNKNOWN, WIN32, XENIX and OTHERS. If additions are needed please contact the author at Support.
