lg.conf(5)                                                          lg.conf(5)



NAME
       lg.conf - looking glass configuration file

DESCRIPTION
       lg.conf contains configuration for the looking glass scripts.

       The syntax is that of perl(1).  It is used to set variables that affect
       run-time behavior and/or to locate resources.

VARIABLES
       The following variables are used (alphabetically):

       LG_AS_REG
              *** not implemented.

       LG_BGP_RT
              Allows show ip bgp neighbor commands that can produce heavy
              output, such as sh ip bgp neighbor <ip> advertised-routes for a
              transit customer when the neighbor address is followed by
              'advertised-routes' for the sh ip bgp neighbor query.

       LG_CACHE_DIR
              Sets the location of the cache directory.  The looking glass
              uses this to hold lock files, log files, and output from cached
              commands.

              Default: ./tmp

              Note that the default is relative to the directory where lg.cgi
              runs in the server's document root (e.g.:
              /usr/local/www/data/lg/tmp).

       LG_CACHE_TIME
              Sets the number of seconds that the looking glass should cache
              output from commands that tend to produce a lot of output, such
              as 'show ip bgp dampened-paths'.

              Default: 600

       LG_CLOGINRC
              Defines the location of the cloginrc(5) that the looking glass
              should use.  The path may be relative to the directory where the
              CGI scripts run in the server's document root.

              Default: $HOME/.cloginrc

              Note that the .cloginrc must be readable by the user or group
              that will be running the CGI and that clogin(1) will not allow a
              world readable .cloginrc.  The user is normally that of the http
              server (httpd).

       LG_IMAGE
              Defines a html image tag (<img>) which, if defined, will be
              included at the top of the looking glass pages.  It may contain
              any html as it is simply handed off to print().

              Example: $LG_IMAGE="<img src=/icons/rancid.gif hspace=0>\n <font
              size=+2>FOO</font>";

       LG_INFO
              Defines information in html format which, if defined, will be
              included at the bottom of the looking glass form page.  It may
              contain any html as it is simply handed off to print().

              Example: $LG_INFO="For Support contact <a
              href=mailto:webmaster@localhost>webmaster</a>";

       LG_LOG Defines the fully qualified path name (i.e.: begins with '/')
              for the log file or the syslog(3) facility to use for logging.
              For syslog, the argument is the lowercase name of a syslog
              facility (see syslog.h) without the 'LOG_' prefix.

              Example: local0

              Default: $LG_CACHE_DIR/lg.log

       LG_ROUTERDB
              Sets the location for the router.db file in rancid's
              router.db(5) format.  It lists the devices that should be
              available to the looking glass users.  Only those devices of
              supported types and with state 'up' are made available.  If not
              defined and the default file does not exist, the looking glass
              will compile a list from the router.db files of all the groups
              present in rancid, that is, the list will be a concatenation of
              the available router.db(5) files.

              Note that if the concatenation method is used, it may be
              necessary to alter the mode of the router.db files in the rancid
              group directories, since rancid's default umask is 027 (see
              rancid.conf(5)).

       LG_STRIP
              Causes the LG to strip login information from the looking glass
              results.  Since Expect often munges disabling echo when
              passwords are entered, this is a SECURITY CONCERN!  However,
              this output can be very useful for debugging clogin problems.

       LG_STYLE
              Defines the URL of a style sheet to be used for HTML formatting.

       PATH   Is a colon separated list of directory pathnames in the file
              system where rancid's login scripts, clogin(1) etc.)  and
              programs needed within these, such as telnet(1), are located.
              Its value is set by configure.  Should it be necessary to modify
              PATH, note that it must include $BASEDIR/bin (see above).

ENVIRONMENT
       LG_CONF
              Location of lg.conf file.  See the FILES section for more
              information.

ERRORS
       lg.conf is interpreted directly by perl(1), so its syntax follows that
       of perl.  Syntax errors may produce quite unexpected results.

FILES
       /etc/lg.conf
              Configuration file described here.

              lg.conf is located by the value of the environment variable
              LG_CONF, in the CWD (current working directory), or the
              sysconfdir defined when rancid was installed, in that order.

SEE ALSO
       cloginrc(5), lg_intro(1), router.db(5)

HISTORY
       In RANCID releases prior to 2.3, lg.conf was located in the util/lg
       sub-directory of the install path.  This was changed to be more
       consistent with common file location practices.
