LibreNMS Devices Disappeared from Web Interface

Posted on by

What do you do when all your devices disappear from the web interface?

Everything still appears to be working. Alerts work.

Running a MySQL command to check if the devices are in the database returns all the devices

mysql -u librenms -p librenms -e 'use librenms ; select hostname,sysName,status from devices where status=1'

If we try going to /addhost we are greeted with an Error You have insuffecient permissions to view this page.

Running ./validate.php returns everything good

Potentially it could be an issue with SElinux or with Apache/NGinx

Running 

audit2why < /var/log/audit/audit.log

Doesn’t return anything

No errors pop up in the Logs

Could be something happened with the LibreNMS user.

Test a different LibreNMS user and all the devices show up.

We’ve now isolated the issue to being something with out user.

After installing OpenVAS you may need to setup a user. Running the following command will create the user admin and will print the password for the user below.

openvasmd --create-user admin

Example output.

User created with password 'b4539967-c521-fe41-d255-aeb53e735h9a'.

If needed you can delete a user with the following command

openvasmd --delete-user=USERNAME

This script adds a new SFTP user with only sftp access.  Refer to this post on setting up a SFTP server.

Download script

wget www.incredigeek.com/home/downloads/scripts/sftpUserAdd.sh

Make executable

chmod +x sftpUserAdd.sh

Run with the new user you want to create.

./sftpUserAdd.sh sftpUsername

You may need to edit the script and modify the location parameters.

#!/bin/bash
# Automatically setup and add SFTP user
# Script creates new user and setups permissions
newUser=$1
sftpDir="/sftp/"
if grep -q ${newUser} /etc/passwd ;then
        echo ${newUser} Already exsists.  Aborting!
        exit 1
else
        mkdir -p ${sftpDir}/${newUser}/files
        useradd -g sftpusers -d ${sftpDir}/${newUser}/files -s /sbin/nologin ${newUser}
        passwd ${newUser}
        chown ${newUser}:sftpusers /sftp/CareMark/files
