Search for the IP-address of the server

In several cases, you should know the IP-address of you RPMS-server. This address should be stored for later reference.

By an app on your phone (Lyrion or Squeezer)

Install the app on your phone
- For Android: Lyrion (F-droid) or Squeezer (Play Store)
Connect to a server (both are auto-discovery, so they detect servers automatically)
Go to the server-specifics in the app en readout the server-address

In a terminal

nmap $(echo "$(hostname -I | cut -d"." -f1-3).1")/24 -p 9000 --open

The result looks something like this:

Nmap scan report for rpms.home (192.168.2.4)
Host is up (0.0062s latency).

PORT     STATE SERVICE
9000/tcp open  cslistener

There might be multiple machines with port 9000 (for LMS) open. You may either try:

watch nmap rpms.home

watch nmap 192.168.2.4  # for example, replace with the real address

The one with an similar output like this, is our RPMS-server:

Nmap scan report for rpms.home (192.168.2.4)
Host is up (0.0032s latency).
Not shown: 993 closed tcp ports (conn-refused)
PORT     STATE SERVICE
22/tcp   open  ssh
80/tcp   open  http
139/tcp  open  netbios-ssn
445/tcp  open  microsoft-ds
5000/tcp open  upnp
9000/tcp open  cslistener
9090/tcp open  zeus-admin

Check for existence of cover.jpg #transcoder

Find folders (album) which do not contain cover.jpg

ssh pi@rpms

And then:

find /media/usbdata/user/music/flac -type d -exec sh -c 'ls -1 "{}"|egrep -iq "^*\.flac$"' ';' '!' -exec sh -c 'ls "{}"|egrep -q "\cover.jpg$" ' ';' -print

Check cover-image dimension #transcoder

Within RPMS, the norm for cover.jpg is 500 x 500. With this command, you can check your collection for these dimensions.

ssh pi@rpms
sudo apt install imagemagic   # If identify (from imagemagic) is not installed

And then:

find /media/usbdata/user/music/flac -name "cover.jpg" -exec identify -format '%wx%h ' {} \; -exec echo {} \; | grep -v 500x500

Backup (remote)

Prepare a local disk

format as (preferably) fat32
label: backup

Connect the local disk to your workstation.

On your (Linux) PC:

sudo nano /usr/local/bin/backupserver

Copy and paste the following text into the text-editor:

#!/bin/bash
sshpass -p rpms rsync --progress --delete -rtv --max-size=4GB --modify-window=2 --exclude Downloads \
pi@rpms:/media/usbdata/user/* \
/media/$USER/BACKUP/user
sync

Note: when the server is not accessible by name, so ping rpms does not work, replace the rpms part in pi@rpms:/media/usbdata/user/* in the actual ip-address, for example [email protected]:/media/usbdata/user/*

Save changes in the editor with Ctrl-O en the exit with Ctrl-X

Make the script executable:

sudo chmod +x /usr/local/bin/backupserver

Execute:

backupserver
