[Earth] Swhoisd Introduction

Swhoisd, Simple WHOIS Daemon, provides the standard Internet whois directory service It is much simpler to setup and administrator than the other whois daemons available, such as RIPE whois or the original SRC whois. This is because it uses a flat-text file, /etc/swhoisd.conf, instead of a complex database. This whois server is recommended only for small databases (preferably under 100 records and no more than 1000).

This daemon conforms to RFC 834 and uses TCP port 43 (service "whois").

[Earth] Swhoisd Example Output

Swhoisd may be accessed by any whois client. For example:

$ whois -h localhost fred
SWHOIS Daemon Release 2.0
Searching for fred. Found 1 record(s) matching fred.

To single out one record, look it up with "!XXX", where XXX is the handle.

Note: for the fwhois client, the command line syntax varies slightly. For example, fwhois fred@localhost

[Earth] Swhoisd Setup

After installing swhoisd, you need to edit file /etc/swhoisd.conf and add your directory information.

To enable the daemon, add a line to your /etc/inetd.conf similar to the following (depending on where you installed the daemon):

  whois   stream  tcp nowait root /usr/local/sbin/in.swhoisd in.swhoisd

For RedHat Linux, file /etc/xinetd.d/whois is created for use by xinetd:

service whois
{
	socket_type     = stream
	wait            = no
	user            = nobody
	server          = /usr/sbin/in.swhoisd
	disable         = no
#       log_type        = FILE /var/log/swhoisd.log
}

Make sure you have inetd (or xinetd) reread it's configuration files by kill -HUP (or by restarting [x]inetd).

For whose who have Apache and PHP, here's a PHP script to query the whois server

For details, see file INSTALL that comes bundled with the package or source.

[Earth] Swhoisd Internationalization and Localization

Swhoisd has been internationalized (I18N). That means, with the proper localized (L18N) message text file, swhoisd can display messages in your local language ("localized"). For example, for Spanish (Español), with LANG=es_MX, the above example would appear as follows:

$ whois -h localhost fred
SWHOIS Daemon Release 2.0
Buscando fred. Se encontraron 1 archivo(s) que corresponde con fred.

Para seleccionar un expediente, busquelo con "!XXX", usando XXX como manija.

To use a message text file for swhoisd, you should already have your $LANG (or $LC_*) environment variable set to your language and country code (e.g., "es_MX"). Set it your /etc/profile file so the in.swhoisd daemon will read it (RedHat uses /etc/sysconfig/i18n). If you start in.swhoisd with xinetd or inetd, check to see that /etc/init.d/*inetd doesn't unset $LANG or set it to another value. For example, RedHat's xinetd sets "$LANG to "en_US" Comment out lines setting these variables: LANG, LANGUAGE, LC_ALL, and LC_MESSAGES

The following language files are available:

Creating a .po Language File
If you don't have the binary .mo file, you need to convert the text file (.po) to a binary .mo file, To convert a .po file to a .mo file, run:
 msgfmt -o swhoisd.es.mo swhoisd.es.po

Substitute "es" by with your two-letter language code.

Installing a .po Language File
Copy the binary .po file to your locale directory. The location of your locale directory varies according to the value of the first two letters of your $LANG environment variable (an example for $LANG = "es_MX" is shown here):
/usr/share/locale/es/LC_MESSAGES/

For example, for German (Deutsche), LANG=de_DE, on RedHat Linux, run this command to install the file in the proper directory:
cp swhoisd.es.mo /usr/share/locale/de/LC_MESSAGES/swhoisd.mo

Adding New Language Files
To localize, copy and translate text file swhoisd.pot with your favorite editor. Send the file to back to me using my web form. To install the file, convert to a .mo file as above. Here's one example for a German de.po file:
msgid "Email address:         "
msgstr "E-Mail Adresse:        "

File swhoisd.po is provided with the binary swhoisd packages, but is also File available here for your convenience.

If you translate file swhoisd.po to another language, please send the file to back to me using my web form.

[Earth] Swhoisd Tips and Patches

The following tips and patches are available for Swhoisd:

[Earth] Swhoisd Help Wanted

If you are interested, contact me using my web form.

  1. Translate message text to non-English languages (see Localization).
  2. Port to other UNIX systems and to MS Windows. (currently available on RedHat Linux and Solaris (SPARC & Intel))
  3. Make completely GNU autoconf-aware.
  4. Convert from a flat-text "database" (swhoisd.conf) to MySQL
  5. Other useful enhancements you may think of.

The following tasks are in progress:

  1. Implement IPv6 for standalone client (automatic for inetd server mode if [x]inetd supports it)
  2. Implement Legacy IPv4 code for pre-IPv6 systems, such as Solaris 7)
