Unable to SSH to RUT956

[shaphiro]

Hi,

I’m trying to connect via SSH to my RUT956, but I’m encountering issues with opening connections from my Ubuntu 24.4 console:

#client
ssh -V
OpenSSH_9.6p1 Ubuntu-3ubuntu13.5, OpenSSL 3.0.13 30 Jan 2024

#server
dropbear -V
Dropbear v2020.81
openssl version
OpenSSL 1.1.1t  7 Feb 2023

ssh root@192.168.1.1
ssh_dispatch_run_fatal: Connection to 192.168.1.1 port 22: unknown or unsupported key type

ssh -o Protocol=2 -o KexAlgorithms=+diffie-hellman-group1-sha1 -o Ciphers=+aes128-cbc root@192.168.1.1
ssh_dispatch_run_fatal: Connection to 192.168.1.1 port 22: unknown or unsupported key type

ssh -o Protocol=1 -o KexAlgorithms=+diffie-hellman-group1-sha1 -o Ciphers=+aes128-cbc root@192.168.1.1
ssh_dispatch_run_fatal: Connection to 192.168.1.1 port 22: unknown or unsupported key type

Is there a way to update the versions of Dropbear and OpenSSL on the RUT956?

Thank you!

UPDATE: I confirm that using an older version of OpenSSL resolves the SSH connection issue, as tested with a Docker container running Ubuntu 20.04.

Hello,

Could you please try executing the following command?
ssh -oHostKeyAlgorithms=+ssh-dss root@192.168.8.109

Please let me know if you still experience the same issue afterward.

Best regards,
