rancid - Cisco configuration filter
rancid [-dlV] (-f filename | hostname)
rancid is a perl(1) script which uses the login scripts (see clogin(1))
to login to a device, execute commands to display the configuration,
etc, then filters the output for formatting, security, and so on.
rancid’s product is a file with the name of it’s last argument plus the
suffix .new. For example, hostname.new.
There are complementary scripts for other platforms and/or
manufacturers that are supported by rancid(1). Briefly, these are:
agmrancid Cisco Anomaly Guard Module (AGM)
arancid Alteon WebOS switches
arrancid Arista Networks devices
brancid Bay Networks (nortel)
cat5rancid Cisco catalyst switches
cssrancid Cisco content services switches

prancid Procket Networks
srancid SMC switch (some Dell OEMs)
trancid Netopia sDSL/T1 routers
tntrancid Lucent TNT
xrancid Extreme switches
xrrancid Cisco IOS-XR devices
zrancid Zebra routing software
The command-line options are as follows:
-V Prints package name and version strings.
-d Display debugging information.
-l Display somewhat less debugging information.
-f rancid should interpret the next argument as a filename which
contains the output it would normally collect from the device (
hostname) with clogin(1).
control_rancid(1), clogin(1), rancid.conf(5)
Cisco IOS offers a DHCP server that maintains a text database which can
be stored remotely or on local storage. If stored locally, the file
changes constantly and causes constant diffs from rancid. If this
file’s name (’ip dhcp database’) matches the regex
dhcp_[^[:space:].].txt, it will be filtered.
For Catalyst switches running CatOS, type cat5, the prompt must end
with ’>’. clogin(1) looks for ’>’ to determine when a login is
successful. For example:
rancid works on Cisco Catalyst 1900 series switches that are running
Enterprise Edition software. This software provides a menu at
connection time that allows a command line interface to be used by
entering ’K’ at the prompt.
