I am a total Newbie to OpenWRT and Linux - so don't be to harsh with me
I got for testing my LTE connection a Espressobin+EM7675 with OpenWRT installed.
Works as a charm - but i want to change my root password.
Within the GUI it is not possible - getting an Error that it can't be changed.
When i connect with ssl to the box and i try to change it with passwd - i am getting the following error message: passwd: /etc/passwd: Read-only file system passwd: can't update password file /etc/passwd
What can i do to change the password to sg stronger?
Hi,
I have a feeling this is a filesystem issue.
The filesystem stays read-only when it doesn't initialise properly.
You should be able to see that by running the df command (post the output here so we get a better idea).
Things to try in order:
reset (which will force a filesystem rebuild on first boot)
flash again
make sure you're flashing the correct firmware file.
If this didn't help, post the output of the df command and let us know which firmware file you're flashing.
Hope that helps!

The thing with new flashing is, that i don't have the image anymore (as it was from another User) and it was as far as i knew "custom build" as at the time there was no EspressoBin + EM7675 Openwrt Image availabe....
And as i am new, i am not 100% sure if there is an image i can savely use to rebuild it so that it is working
But this is what currently is installed:
There is stable version for Espressobin. You don't need to use the snapshot, which is nightly built. https://downloads.openwrt.org/releases/19.07.2/targets/mvebu/cortexa53/
Take a backup of your configuration, reset the device and flash the new image (without keeping settings).
Then I would advice you to use the backup files as reference only and restore the configuration manually.
