       lg.conf - looking glass configuration file

       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.

       The following variables are used	(alphabetically):

	      *** not implemented.

	      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.

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

	      Default: ./tmp

	      Note  that the default is	relative to the	directory where	lg.cgi
	      runs    in     the     server's	  document     root	(e.g.:

	      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

	      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).

	      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

	      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

       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

	      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

	      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.

	      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).

       Queries	      ...................................

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

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

	      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.

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

       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.
