paxut.blogg.se - Remove dropbear ssh server on router

I added my usual public key file to dropbear's known hosts in the server's /etc/initramfs-tools/root/.ssh/authorized_keys and tried to ssh with my usual key. These are scripts that worked in older install!

Custom hook scripts seem to be partially ignored.

With which dropbear drops to password authentication and wants the root password, that is not set. Solved: Dropbear wants a passphrase for the key, which I do not have.

Dropbear ignores all public keys other than its own in /etc/initramfs-tools/root/.ssh/authorized_keys (tested with dss - maybe also rsa).

So I tried the listed wrong IP with: ssh -vv -i ~/.ssh/dropbear_dss_host_key -o 'UserKnownHostsFile=~/.ssh/known_hosts.initramfs' That connects to dropbear but: I found in my router's "connected devices" site, that the server has the ip 192.168.0.27 despite my configuration. To my surprise two three things are malfunctioning: So I copied the auto-generated ssh-key and did a minimal configuration of dropbear. o 'UserKnownHostsFile=~/.ssh/known_hosts.initramfs' # on client Ssh -vv -i ~/.ssh/id_rsa_dropbear_server \ Scp server:/tmp/id_rsa ~/.ssh/id_rsa_dropbear_server # on client Sudo cp /etc/initramfs-tools/root/.ssh/id_rsa /tmp # BETTER! # WRONG: sudo cp /etc/dropbear/dropbear_*_host_key /tmp
