Dropbear SSH can not start #23

Hi! First of all, thank you for your project!

I have Aqara Gateway 2 (ZHWG11LM) and trying to get root by your instructions. I have a problem with dropper ssh. It's not start and I see the next logs:

...
==========================================
======== ^_^ start miot hkbridge =========
==========================================
Starting Dropbear SSH server: fac_test bulid time:04:06:52 Oct 19 2018
gobal_cmd_list size 3204
Input cmd:Pseudo-terminal will not be allocated because stdin is not a terminal.
dropbearkey: Could not resolve hostname rsa: Name or service not known

As I understand, ssh service didn't run, because I cannot connect to it.

This is start gateway logs (with some versions of software and hardware) if it help you:

Some Aqara firmware binaries include dropbear compiled without ssh server. It can be used only as a client. To fix this issue you can replace dropbearmulti with the one from xiaomi dgnwg05lm firmware. It is already uploaded to github.

I suppose you can use the following commands under root user on your gateway:

mv /usr/sbin/dropbearmulti /usr/sbin/dropbearmulti.backup
echo -e "GET /openlumi/openlumi.github.io/master/files/dropbearmulti HTTP/1.0\nHost: raw.githubusercontent.com\n" | openssl s_client -quiet -connect raw.githubusercontent.com:443 -servername raw.githubusercontent.com 2>/dev/null | sed '1,/^\r$/d' > /usr/sbin/dropbearmulti
chmod +x /usr/sbin/dropbearmulti
