NAME

6       lg.conf - looking glass configuration file
7

DESCRIPTION

9       lg.conf contains configuration for the looking glass scripts.
10
11       The syntax is that of perl(1).  It is used to set variables that affect
12       run-time behavior and/or to locate resources.
13

VARIABLES

15       The following variables are used (alphabetically):
16
17       LG_AS_REG
18              *** not implemented.
19
20       LG_BGP_RT
21              Allows show ip bgp neighbor  commands  that  can  produce  heavy
22              output,  such as sh ip bgp neighbor <ip> advertised-routes for a
23              transit customer  when  the  neighbor  address  is  followed  by
24              'advertised-routes' for the sh ip bgp neighbor query.
25
26       LG_CACHE_DIR
27              Sets  the  location  of  the cache directory.  The looking glass
28              uses this to hold lock files, log files, and output from  cached
29              commands.
30
31              Default: ./tmp
32
33              Note  that the default is relative to the directory where lg.cgi
34              runs    in     the     server's     document     root     (e.g.:
35              /usr/local/www/data/lg/tmp).
36
37       LG_CACHE_TIME
38              Sets  the  number of seconds that the looking glass should cache
39              output from commands that tend to produce a lot of output,  such
40              as 'show ip bgp dampened-paths'.
41
42              Default: 600
43
44       LG_CLOGINRC
45              Defines  the  location of the cloginrc(5) that the looking glass
46              should use.  The path may be relative to the directory where the
47              CGI scripts run in the server's document root.
48
49              Default: $HOME/.cloginrc
50
51              Note  that  the  .cloginrc must be readable by the user or group
52              that will be running the CGI and that clogin(1) will not allow a
53              world readable .cloginrc.  The user is normally that of the http
54              server (httpd).
55
56       LG_IMAGE
57              Defines a html image tag (<img>)  which,  if  defined,  will  be
58              included  at the top of the looking glass pages.  It may contain
59              any html as it is simply handed off to print().
60
61              Example: $LG_IMAGE="<img src=/icons/rancid.gif hspace=0>\n <font
62              size=+2>FOO</font>";
63
64       LG_INFO
65              Defines  information  in  html format which, if defined, will be
66              included at the bottom of the looking glass form page.   It  may
67              contain any html as it is simply handed off to print().
68
69              Example:       $LG_INFO="For       Support       contact      <a
70              href=mailto:webmaster@localhost>webmaster</a>";
71
72       LG_LOG Defines the fully qualified path name (i.e.:  begins  with  '/')
73              for  the  log file or the syslog(3) facility to use for logging.
74              For syslog, the argument is  the  lowercase  name  of  a  syslog
75              facility (see syslog.h) without the 'LOG_' prefix.
76
77              Example: local0
78
79              Default: $LG_CACHE_DIR/lg.log
80
81       LG_ROUTERDB
82              Sets   the   location   for   the  router.db  file  in  rancid's
83              router.db(5) format.   It  lists  the  devices  that  should  be
84              available  to  the  looking  glass users.  Only those devices of
85              supported types and with state 'up' are made available.  If  not
86              defined  and  the default file does not exist, the looking glass
87              will compile a list from the router.db files of all  the  groups
88              present  in rancid, that is, the list will be a concatenation of
89              the available router.db(5) files.
90
91              Note that if  the  concatenation  method  is  used,  it  may  be
92              necessary to alter the mode of the router.db files in the rancid
93              group directories, since rancid's  default  umask  is  027  (see
94              rancid.conf(5)).
95
96       LG_STRIP
97              Causes  the LG to strip login information from the looking glass
98              results.   Since  Expect  often  munges  disabling   echo   when
99              passwords  are  entered,  this  is a SECURITY CONCERN!  However,
100              this output can be very useful for debugging clogin problems.
101
102       LG_STYLE
103              Defines the URL of a style sheet to be used for HTML formatting.
104
105       PATH   Is a colon separated list of directory  pathnames  in  the  file
106              system  where  rancid's  login  scripts,  clogin(1)  etc.)   and
107              programs needed within these, such as  telnet(1),  are  located.
108              Its value is set by configure.  Should it be necessary to modify
109              PATH, note that it must include $BASEDIR/bin (see above).

ENVIRONMENT

114       LG_CONF
115              Location of lg.conf  file.   See  the  FILES  section  for  more
116              information.
117

ERRORS

119       lg.conf  is interpreted directly by perl(1), so its syntax follows that
120       of perl.  Syntax errors may produce quite unexpected results.
121

FILES

123       /etc/rancid/lg.conf
124              Configuration file described here.
125
126              lg.conf is located by the  value  of  the  environment  variable
127              LG_CONF,   in  the  CWD  (current  working  directory),  or  the
128              sysconfdir defined when rancid was installed, in that order.

HISTORY

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