Hi everyone.

I’m trying to connect to board via SSH, but I got this message:

Unable to negotiate with 192.168.15.4 port 22: no matching host key type found. Their offer: ssh-rsa

Thanks for any help!

Hi,

Your ssh client has the ssh-rsa algorithm disabled by default, but the ssh server of the multimedia image supports only ssh-rsa (without reconfiguration). By using the HostKeyAlgorithm option of the ssh client you can enable or disable specific algorithms.

Try the following to enable ssh-rsa explicitly for the session (with root user):

ssh -oHostKeyAlgorithms=+ssh-rsa root@192.168.15.4

Lukas
