.\" .\" $Id: rancid.conf.5.in,v 1.15 2005/08/15 00:41:51 heas Exp $ .\" .hys 50 .TH "rancid.conf" "5" "13 August 2005" .SH NAME rancid.conf \- rancid environment configuration file .SH DESCRIPTION .B rancid.conf contains environment configuration information for .BR rancid-run (1) and .BR rancid (1) including shell PATH, list of rancid groups, etc. and is read by several scripts at run-time, including .BR rancid-run (1). .PP The syntax of .B rancid.conf is that of .IR sh (1). .B rancid.conf is used to set environment variables used by other rancid scripts to effect their run-time behavior or to enable them to find their resources. .PP .SH VARIABLES The following variables are used (listed alphabetically): .PP .Bl -tag -width flag .\" .TP .B BASEDIR BASEDIR is the directory where .B rancid-run's log directory, the revision control system's repository, and rancid group directories will be placed. .sp Its value is configure's localstatedir and should be modified if rancid is moved to a new location in the file system without re-installing from the distribution. .sp Default: @localstatedir@ .\" .TP .B CVSROOT .IR cvs (1) and .IR rancid-cvs (1) use this environment variable to locate the CVS repository. In some cases, and for Subversion, it is used as an argument to commands. It should not be necessary to alter it. .sp Default: $BASEDIR/CVS .\" .TP .B FILTER_PWDS Determines which passwords will be filtered from configs. The value may be "NO", "YES", or "ALL" to filter none of the passwords, only those which are reversable or plain-text, or all (plus ssh keys, etc), respectively. .sp Default: YES .sp Note: a value of "NO" could be a security issue since diffs are sent via e-mail. A value of "ALL" is encouraged. .sp Note: .B FILTER_PWDS does not affect the handling of SNMP community strings. see .B NOCOMMSTR below. .sp Note: passwords whose value cycles and would produce erroneous diffs are always filtered (e.g.: Alteon passwords). .\" .TP .B LIST_OF_GROUPS Defines a list of group names of routers separated by white-space. These names become the directory names in $BASEDIR which contain the data for that set of devices. .BR rancid-run (1) also uses this variable to determine which device groups it should collect. Choose these names to be descriptive of the set of devices and do not use spaces, unprintable characters, etc. .sp Example: LIST_OF_GROUPS="UofO USFS" .sp Two groups are defined; UofO (University of Oregon) and USFS (US Forest Service). Each will have a directory created (see .IR rancid-cvs (1)) $BASEDIR/UofO and $BASEDIR/USFS respectively, which will contain their data. .sp Each group must also have aliases for the administrative and diff recipients set-up in .IR /etc/aliases . For example: .sp .in +1i .nf @MAILPLUS@uofo: frank @ADMINMAILPLUS@uofo: joe,bob @MAILPLUS@usfs: frank @ADMINMAILPLUS@usfs: joe,bob .fi .sp .in -1i .\" .TP .B LOCKTIME Defines the number of hours a group's lock file may age before rancid starts to complain about a hung collection. The default is 4 hours. .\" .TP .B LOGDIR Directory where .B rancid-run places log files. .sp Default: $BASEDIR/logs .\" .TP .B MAILDOMAIN Define the domain part of addresses for administrative and diff e-mail. The value of this variable is simply appended to the normal mail addresses. For example @MAILPLUS@usfs@example.com, if .B MAILDOMAIN had been set to "@example.com". .\" .TP .B MAILHEADERS Define additional mail headers to be added to rancid mail, such as Precedence or X- style headers. Individual headers must be separated by a \\n (new line). .sp Default: Precedence: bulk .sp Example: Precedence: bulk\\nX-clamation: beef cake .\" .TP .B MAX_ROUNDS Defines how many times rancid should retry collection of devices that fail. The minimum is 1. .sp Default: 4. .\" .TP .B NOCOMMSTR If set, .IR rancid (1) will filter SNMP community strings from configs. Otherwise, they will be retained and may appear in clear-text in e-mail diffs. By default, this is not set. .\" .TP .B NOPIPE If set, .IR rancid (1) will use temporary files to save the output from the router and then read these to build the file which will be saved in CVS (or Subversion). Otherwise, an IPC pipe will be used. We have found that the buffering mechanisms used in perl and expect are heinous. Using temporary files may result in a noticeable improvement in speed. By default, this is not set. .\" .TP .B OLDTIME Specified as a number of hours, OLDTIME defines how many hours should pass since a successful collection of a device's configuration and when .IR control_rancid (1) should start complaining about failures. The value should be greater than the number of hours between .B rancid-run cron runs. .sp Default: 4 .\" .TP .B PAR_COUNT Defines the number of rancid processes that .IR par (1) will start simultaneously as .IR control_rancid (1) attempts to perform collections. Raising this value will decrease the amount of time necessary for a complete collection of a (or all) rancid groups at the expense of system load. The default is relatively cautious. If collections are not completing quickly enough for users, use trial and error of speed versus system load to find a suitable value. .sp Default: 5 .\" .TP .B PATH Is a colon separate list of directory pathnames in the the file system where rancid's .IR sh (1) and .IR perl (1) scripts should look for the programs that it needs, such as .IR telnet (1). Its value is set by configure. Should it be necessary to modify PATH, note that it must include @bindir@. .\" .TP .B RCSSYS Sets which revision control system is in use. Valid values are .B cvs for CVS or .B svn for Subversion. .sp Default: cvs .\" .TP .B TERM Some Unix utilities require TERM, the terminal type, to be set to a sane value. Some clients, such as .IR telnet (1) and .IR ssh (1) , communicate this to the server (i.e.: the remote device), thus this can affect the behavior of login sessions on a device. The default should suffice. .sp Default: network .\" .TP .B TMPDIR Some Unix utilities recognize TMPDIR as a directory where temporary files can be stored. In some cases, rancid utilizes this directory for lock files and other temporary files. .sp Default: /tmp .\" .PP Each of these are simply environment variables. In order for them to be present in the environment of child processes, each must be exported. See .IR sh (1) for more information on the built-in command export. .SH ERRORS .B rancid.conf is interpreted directly by .IR sh (1), so its syntax follows that of the bourne shell. Errors may produce quite unexpected results. .SH FILES .Bl -tag -width @sysconfdir@/rancid.conf -compact .TP .B @sysconfdir@/rancid.conf Configuration file described here. .El .\" .SH "SEE ALSO" .BR control_rancid (1), .BR rancid (1), .BR rancid-cvs (1), .BR rancid-run (1) .\" .SH HISTORY In RANCID releases prior to 2.3, .B rancid.conf was named .B env and located in the bin directory. This was changed to be more consistent with common file location practices.
