How to read the firmware version of a Teltonika RUTOS device over SSH

Teltonika RUTOS devices (RUTX10, TRB140, RUT241, …) store their firmware version in /etc/version. To read it over SSH:

get-version.sh

ssh root@<device-ip> 'cat /etc/version'

Example output:

example.txt

TRB1_R_00.07.24.3

The format is <model>_R_<version>, e.g. TRB1 = TRB140, RUTX = RUTX10 / RUTX11, followed by the RutOS release (07.24.3).

Alternatives

alternatives.sh

# OpenWrt base version + target info
ssh root@<device-ip> 'cat /etc/os-release'

# JSON: model, board, firmware name in release.description
ssh root@<device-ip> 'ubus call system board'

ubus call system board returns structured JSON — handy for scripts since it also includes the model name, hostname and kernel version.

Scripted example

script.sh

ssh -o BatchMode=yes root@192.168.88.1 'cat /etc/version' | grep -o '[0-9.]*$'
# → 07.24.3

The version is also printed in the SSH login banner/MOTD on RutOS, so parsing /etc/version is the cleaner machine-readable option.
