Gateway not starting?

[bvlet]

I found your website and followed everything to the letter. I managed to get the password, login, put serialgateway in the /tuya/ dir and execute the script. I get a new tuya_start.original.sh, and anew tuya_start.sh. When I use cat to check the new files I think the output is correct:

But: After reboot I can't reach the unit through home assistant, and i am still able to SSH to port 2333. SO something is not completely working. Do you have a hint for me to take me to the next and last step?

Thanks!

I was installing the MobaXterm and is getting the same error so i think its some security things that is not installed / supported in the tuya Linux but its working. Your startup command looks OK but have you setting the rights OK ?

Sorry i was forgetting. xauth is used by X-server that is not installed on the tuya GW = OK the terminal cant starting it.

Does "ps" show the gateway is running? The 2333 thing is expected - I might have done more to mine so I'm going to flash mine back to factory and repeat the procedure. Watch this space!

[MattWestb]

My is always being 127 :

  127 root       188 S    /tuya/serialgateway

And its looks the 2333 is not being changed of the new startup script (and not patched other things so much).

[banksy-git]

Ok, I remember - I didn't like the tuyadropbear or its anti brute force mechanism so I disabled it and that caused it to revert to the "standard" dropbear. You can do it too with:

if [ ! -f /tuya/ssh_monitor.original.sh ]; then cp /tuya/ssh_monitor.sh /tuya/ssh_monitor.original.sh; fi

echo "#!/bin/sh" >/tuya/ssh_monitor.sh 

I'll update the guide accordingly. :)

[bvlet]

Almost works, the echo has to be:

# echo "#!/bin/sh" >/tuya/ssh_monitor.sh Otherwise you'll get

# echo "#!/bin/sh" >ssh_monitor.sh -sh: can't create ssh_monitor.sh: Read-only file system

After that you can SSH through port 22

Fixed! Thanks @bvlet
