Installing

1. verify that you have the prerequisites installed

   • perl the software has been tested with 5.6.1 and should work with most other versions of perl 5 as well. Find perl at www.perl.org

   Note: there are issues with some versions of perl on some operating systems, see bugs.html for additional details.

   • sendmail and qpage are recommended. either or both can be used to send notifications.
   • fping is used by the Ping Monitoring module for ping tests. While this is not required, it is highly recommended. Find fping at www.fping.com
   • a cgi capable web server, such as apache. Find apache at http://httpd.apache.org/
   • Berkeley DB and perl DB_File Find DB at http://www.sleepycat.com/download.html
   • B_File ships with perl.

   Alternatively, ndbm, odbm, sdbm, or gdbm can be used, but they have not been extensively tested.

   • an understanding of UNIX file permissions and how to use and operate your web server.

1. unbundle the tarball

2. run ./Configure if upgrading from 3.2 or later, you can run ./Configure --upgrade

3. answer any questions it asks

4. run make

5. as root, run make install

6. create 2 files in the data directory:

   1. config
   2. users

in addition to the documentation, the tarball contains examples in the 'examples' directory.

1. configure your web server

   • be sure that $datadir is writable by the www user (or whatever uid your web server runs as)
   • copy icons to somewhere accessible by your web server (these locations get specified in config file, above) or feel free to replace them with your own icons, or no icons at all.

2. start the argus server by running argusd or install the rc.argusd script as appropriate for your system.

3. check the argus log file ($datadir/log) and/or your syslog logs to verify that argus is operating correctly.

4. load the argus cgi interface in your web browser, and verify that everything is configured correctly.

5. argusd to start argus

Argus comes with a argusctl program which can be used to control or get data from the running argus server.

For a list of poorly documented commands that are supported, you can run either: argusctl help or argusd -C

Some examples of useful commands:

• argusctl hup - reload the config file
• argusctl -k console - display log messages
• argusctl ovlist - list everything currently in override
• argusctl status - display current status
• argusctl shutdown - shut down argus
