I am tyring to ssh to a remote server using dropbear from my embedded board (with custom Linux distribution built using yocto). By deafult the dropbear ssh client is used instead of openssh client. When I try to establish connection I get
ssh: Connection to [email protected]:22 exited: No auth methods could be used.
ssh command I am using:
ssh -i <>/.ssh/id_ecdsa -p 22 -R <remote_port>:localhost:22 [email protected]
The <>/.ssh/id_ecdsa private key is generated using
dropbearkey -f /home/root/.ssh/id_ecdsa -t ecdsa -b 256
Also, I have added pub key to authorized_keys in /home/root/.ssh/ with
dropbearkey -y -f id_ecdsa | grep "^ecdsa-sha2-nistp256 " >> authorized_keys
Can anyone please let em know what is the issue here and how to resolve it?
Thanks in advance
P.S: Please let me know if any info is missing here
