Using rsync on Android to syncronise my Music library
Never
2026-01-12
────────────────────
SETUP TERMUX
Install Termux using F-Droid.
Update software repos.
pkg update
Grant file access permissions using.
termux-setup-storage
ESTABLISHING AN SSH CONNECTION
If network (such as eduroam) is blocking ssh trafic between machines,
open a Wi-Fi Hotspot on your Linux machine and connect the Android
device to it before using  rsync  or  ssh .
Configuring Android
Install the openssh server on Termux.
pkg install openssh
Start the ssh server daemon.
sshd
Get the ip address of the Android machine (in the Hotspot).
ifconfig
Warning: cannot open /proc/net/dev (Permission denied). Limited output.
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
 inet 127.0.0.1 netmask 255.0.0.0
 unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 1000 (UNSPEC)

 unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 1000 (UNSPEC)
wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
 inet 10.42.0.200 netmask 255.255.255.0 broadcast 10.42.0.210
 unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 1000 (UNSPEC)
In this case 10.42.0.200.
The ssh server should now be running and listening on port 8022. You can
check by running
nmap -Pn <ip_address>
For me  <ip_address>  whould be 10.42.0.200.
Get the username.
whoami
u0_a700
Set a password for this user.
passwd
Connecting to Android via ssh
Make sure you have an ssh key pair on the Linux system. If not generate
one using  ssh-keygen .
Now connect to Android by  ssh .
ssh <username>@<ip_address> -p 8022
SYNCRONISING FILES WITH RSYNC
Install  rsync  on Termux and Linux. Make sure to keep your own openssl
config.
pkg install rsync
Now on your Linux machine, syncronise your Music library with rsync.
rsync -av -e "ssh -p 8022" ~/Music <username>@<ip_address>:/data/data/com.termux/files/home/storage/music
