Install Oxidized on LibreNMS

Install Oxidized

Install Instructions from here

Install prerequisites

sudo yum -y install make cmake which sqlite-devel openssl-devel libssh2-devel ruby gcc ruby-devel libicu-devel gcc-c++

Install Ruby Gems

gem install oxidized
gem install oxidized-script oxidized-web

If you run into issues with installing the oxidized-web gem because of a ruby version, try installing ruby 2.6.1 via rvm the docs say install 2.1.2, but was having issues with it. 2.6.1 seems fine.

Install Oxidized

gem install oxidized 
gem install oxidized-script
gem install oxidized-web

Run Oxidized twice to generate the config

oxidized

If you have issues running oxidized due to an invalid or self signed ssl cert, you can either fix the cert or ignore it in the oxidized config. https://github.com/ytti/oxidized/pull/618/files

Modify the Oxidized config file in “/root/.config/oxidized/config” to look like this.

Modify the http portion of the config file to look like the following.

http:
url: https://localhost/api/v0/oxidized
scheme: https
secure: false

Setup Config

vi .config/oxidized/config

Setup as system service

Find the “oxidized.service” file, should be in

/usr/local/rvm/gems/ruby-2.6.1/gems/oxidized-0.25.1/extra/oxidized.service

and copy it to

/usr/lib/systemd/system/

Edit it and change the user and try to launch it

systemctl start oxidized

If it fails, you may need to substitute the ExecStart= variable to the following more info

ExecStart=/usr/local/rvm/gems/ruby-2.6.1/wrappers/oxidize

Change the ruby number if yours is different.

Enable the service on system boot up and start

systemctl enable --now oxidized

Check that oxidized is running

systemctl status oxidized

LibreNMS config

Add the following to your /opt/librenms/config.php config file.

# Oxidized configuration
$config['oxidized']['enabled'] = TRUE;
$config['oxidized']['url'] = 'http://127.0.0.1:8888';
$config['oxidized']['features']['versioning'] = true;
$config['oxidized']['group_support'] = true;
$config['oxidized']['default_group'] = 'default';
$config['oxidized']['reload_nodes'] = true;# Oxidized configuration
$config['oxidized']['enabled'] = TRUE;
$config['oxidized']['url'] = 'http://127.0.0.1:8888';
$config['oxidized']['features']['versioning'] = true;
$config['oxidized']['group_support'] = true;
$config['oxidized']['default_group'] = 'default';
$config['oxidized']['reload_nodes'] = true;
$config['oxidized']['ignore_os'] = array('linux','windows');
$config['oxidized']['ignore_types'] = array('server','power');

LibreNMS should now feed Oxidized the devices.

You can check in the LibreNMS interface to see if it is getting the configs. https://librenms/oxidized

where librenms is your LibreNMS servers ip/hostname.

Backup Android with adb on Windows

Install SDK

Install Android Studio. This will install the SDK and tools like adb and fastboot

Download from here

To run adb, you’ll need to be in the same directory as it, so open a Command Prompt and cd to the following directory.

cd %APPDATA%..\Local\Android\Sdk\platform-tools

Full directory path is

C:\Users\UserName\AppData\Local\Android\Sdk\platform-tools

Backup Android

On your Android device you will need to enable USB debugging from the developer options. Enable the developer options if you have not already.

When you plug your phone in it should ask you to Allow USB debugging. Hit OK to enable it.

Now run the backup command from your computer. Replace UserName with your computers User Name

adb backup -apk -obb -shared -all -f \Users\UserName\Desktop\android-backup.ab

On your phone you should get a window that shows Full Backup

Add optional password for backup and hit “Back up my data on phone”

Now Wait for it to finish…

Restore Backup

adb restore C:\Users\UserName\android-backup.ab

Should get a restore window on your phone, hit restore and wait.

Errors

error: device unauthorized.
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill-server' if that seems wrong.
Otherwise check for a confirmation dialog on your device.

USB Debugging is not allowed for computer. Try replugging the USB cable and accepting the USB Debugging.

Mikrotik Backup Script

This is a Linux script for creating and backing up backups on Mikroitk routers.

Features

  • Creates the backups automatically, no need to manually create a backup on the Mikrotik
  • Uses SSH and SCP for encrypted communication between the router and the server
  • Runs on linux
  • Easy to use command line interface
  • Can back up single or multiple routers

Future Features

These are features I am planning on adding to the script in the future

  • Ability to compare backups and remove duplicates
  • Make the script smarter so it can detect a backup on a router and leave it instead of deleting it
  • Add better logging
  • Add the functionality to upload the backups to an online service like DropBox, or OneDrive automatically
  • Add alert mechanism to alert you if a backup failed or router is unreachable

Current Bugs or limitations

  • Deletes all backups off of the router, so if you manually created a backup it will delete it without asking
  • To stop backing up a router, you’ll need to manually delete the IP address out of the IP database i.e(ip.lst file.)
  • It does not currently have the ability to delete backups

 

Requirements

  1. Linux box to run the script from and to store the backups.  You can run it from a laptop or VirtualBox.
  2. You’ll need the following programs for this script to work(fping, sshpass)
  3. The Linux box need to be able to ping the routers, if it can’t the script will fail

Installing

Download program

wget www.incredigeek.com/home/downloads/mtbackup/mtbackup.sh
chmod +x mtbackup.sh

Now open up the script and edit the variables at the top for your username, password, and where you want the backups.

 nano mtbackup.sh

When you have finished editing the variables, hit CTRL+x, and then “y” and then “enter” to save the file.

If you want to setup the script to backup on a regular basis then setup the script to run in cron.

Run “crontab -e” and add the following line

10 1 * * 1 cd /root/mtbackup-1.0/ & sh mtbackup -b

Hit CTRL+x, and then “y” and then “enter” to save the file.

Adding routers to backup

Adding routers is really easy.  All you have to do is run the script with the -a option and then the ip address and the script will check if it can reach the IP and then add it to the IP Database i.e.(ip.lst file that contains all the routers ip addresses)
./mtbackup.sh -a 192.168.88.1

Example:

[root@localhost mtbackup-1.0]# ./mtbackup.sh -a 192.168.88.1

Adding 192.168.88.1 to the ip DB
Added 192.168.88.1 to ipDB
[root@localhost mtbackup-1.0]#

Backing up all routers

You can manually backup all the routers by running the script with just the “-b” option.  It’ll read every IP in the IP database and create a backup for each one and put it in the backup folder with is normally “./backups”, you can change it in the variables portion of the script.

./mtbackup.sh -b

How to export/import a XenServer VM form the Command Line

We can list the VM’s by running

xe vm-list

You can export a VM using either the name of the VM or by using the uuid.  The above command list both so you can use which ever one you want.

You will also need to shutdown the VM your going to export.

xe vm-shutdown vm=ubuntu

 

Export by Name
The name of the VM is”ubuntu”.

xe vm-export vm=ubuntu filename=/backup/ubuntu.xva

Export using uuid

xe vm-export uuid=b24dcd65-5e12-4576-2f39-46ecab9362ab filename=/backup/ubuntu.xva

 

Importing VM

xe vm-import vm=centos5 filename=/backup/ubuntu.xva

Create an Image of a SD Card

The following command works on both OS X and Linux.  It creates an image from the SD card called raspi.img which you can later use to clone to another SD Card or just keep as a backup.  It is exceptionally useful for backing up a Raspberry Pi.

Replace “mmcblk0” with your SD cards name.  Take a look at this post if you need help finding the name.

sudo dd if=/dev/mmcblk0 of=~/raspi.img

How to Backup a WordPress Site from the Command Line

There are 2 things we need to do when we backup a WordPress site.

  1. Backup the WordPress files
  2. Backup The WordPress database

Backup the WordPress files

We can backup the files with tar by running the following command.  Replace (/Path/to/wpdir) with the actual path.

#  tar -zcvf wp-backup.tgz /Path/to/wpdir/

This can take awhile depending on how big your site is.

Backup the Database

The following command will backup the WordPress database into a gziped sql file.

mysqldump -u username -p[root_password] database_name > wp-database.sql && gzip wp-database.sql

You can find the MySQL Database, username, and password in the wp-config.php file in the wordpress directory

You should now have two files, wp-backup.tgz and wp-database.sql.qz, you’ll need both of these to restore the backup.
