Hello, I am using Guacamole 1.4.0 to connect a Ubuntu 22.04 machine with OpenSSH Server with username and password, all with default settings, but failed. The guacd log only tells “SSH handshake failed”, while /var/log/auth.log in the Ubuntu machine tells “Unable to negotiate with UBUNTU-ADDRESS port XXXXX: no matching host key type found. Their offer: ssh-rsa,ssh-dss [preauth]”.
I can successfully connect to the Ubuntu machine after adding “HostKeyAlgorithms +ssh-rsa” to /etc/ssh/sshd_config in the Ubuntu machine, but is there anything I can do from Guacamole side? From the man page of sshd_config <https://man.openbsd.org/sshd_config#HostKeyAlgorithms>, ssh-rasa and ssh-dns is not included by default. Thanks, Yang
