Building openwrt image with openssh-server

``im trying to build an image with packages"-dropbear openssh-server" it installs openssh-server but i cannot access luci nor ssh in because it requires a password i have tried adding my keyfile in files/root/.ssh/authorized_keys

also tried setting a password like this:

mkdir ./files/etc/uci-defaults/
cat <<'__EOF__' > ./files/etc/uci-defaults/

[ "$(uci -q get system.@system[0].init)" = "" ] && exit 0
[ -e /etc/init ] && exit 0
touch /etc/init
uci batch <<EOC
    set system.@system[0].init='initiated'

/usr/bin/passwd root <<EOP

all to no avail i hope someone has a suggestion

i also tried putting the sshd_config in /etc/ssh/ to permit root login but still nothing, is there something that happens during the dropbear installation that makes the password empty? because luci and ssh both want a password that i dont know nor can i find where that has been set

LuCI login should not be effected by changing dropbear to ssh. LuCI does not have set a password initially. It only has if you decide on an upgrade to preserve settings. Your script to set a password looks a bit overkill to me.

A simple one-liner will do it:

echo -e 'MyPassWord\nMyPassWord' | passwd root

Beside that you need sshd_config placed with allowing root login also. In case you want dropbear paralell installed you have to adjust ports as well.

Port 2222 # or whatever port you want
PermitRootLogin yes
PubkeyAuthentication yes
PasswordAuthentication yes
PermitEmptyPasswords no

Put this just at the end of the regular sshd_config and place it accordingly /files/etc/ssh/ like the script.

still no dice and i dont know why it requires a password either but i am not replacing dropbear with openssh-server i dont install dropbear at all maybe the issue is there

i build the image with the following line:

make image PROFILE="rpi-4" PACKAGES="bash luci-ssl nano shadow sudo openvpn luci-app-wireguard wireguard-tools luci-app-vpnbypass openssh-server luci-app-pbr luci-app-ddns -dropbear" FILES="files"

the following is the sshd_config i put

strange@echelon:~/Downloads/install/openwrt/pi4.imagebuilder/files/etc/ssh$ cat sshd_config

i've tried running it with just that and i get password failures then
so then i've tried your echo way of setting a password:

strange@echelon:~/Downloads/install/openwrt/pi4.imagebuilder/files/etc/uci-defaults$ cat 

[ "$(uci -q get system.@system[0].init)" = "" ] && exit 0
[ -e /etc/init ] && exit 0
touch /etc/init
uci batch <<EOC
    set system.@system[0].init='initiated'

echo -e 'test\ntest' | passwd root

same error on trying to ssh root@ get a response but wont accept password "test"

i should flash factory image right?

1.) I don't really know where you've got the script above. For me it looks like it does unnecessary stuff. There is no /etc/init file on my installation. So its outdated at least. Delete it and use the one-liner only.

2.) You've configured the device for in an extra config file correctly?

3.) Just try out if dropbear is a hard requirement and install both. It won't hurt for testing. Kepp in mind to adjust listen ports.

4.) You use factory image for initial installation only. If you've installed it already use sysupgrade.

thank you i didnt need the clutter indeed
