Rancid Integration with LibreNMS
Librenms generate a list of hosts that can be monitored by RANCID. We installed and running Rancid, and you just need to create and update the file ‘router.db’

Ubuntu Rancid Install
The options shown below also contains the default values.
sudo apt-get install rancid subversion
Edit Rancid config file to use subversion or git instead of default cvs, and adds a group:
sudo nano /etc/rancid/rancid.conf
LIST_OF_GROUPS=”librenms core”
Now change these two lines:
CVSROOT=$BASEDIR/CVS; export CVSROOT
RCSSYS=cvs; export RCSSYS
to:
CVSROOT=$BASEDIR/SVN; export CVSROOT
RCSSYS=svn; export RCSSYS
NOTE – This only creates 1 group! You can of course make more when you get the hang of it, this is just a basic ‘Need it to work” deal.
Run this command to create the folder structure:
sudo passwd rancid
su – rancid
/var/lib/rancid/bin/rancid-cvs
NOTE – do NOT change cvs to svn here! Leave command as is!
Get a list of devices from Librenms you can pull configs from:
cd /opt/librenms/scripts
sudo ./gen_rancid.php
Copy the output. Replace all “:” with “;” example:
alphcr1:cisco:up will change to:
alphcr1;cisco;up
copy and past results into the below file:
sudo nano /var/lib/rancid/librenms/router.db
AND
sudo nano /var/lib/rancid/core/router.db
# You can enter some sensible text here to define the device below
add user {192.168.88.1} {rancid}
add password {192.168.88.1} {sshpassword} {enablepassword}
add method {192.168.88.1} {ssh:2223}
#add autoenable {192.168.88.1} 1
# You can enter some sensible text here to define the device below
add user {192.168.88.2} {rancid}
add password {192.168.88.2} {telnetpassword} {enablepassword}
add method {192.168.88.2} {telnet}
#add autoenable {192.168.88.2} 1
Make sure your config files are there 🙂
sudo usermod -a -G rancid www-data ***** run as root user
sudo usermod -a -G rancid librenms
$config[‘rancid_configs’][‘core’] = ‘/var/lib/rancid/core’;
