Hello, Firstly sftp don't save the ecdsa-sha2-nistp521 public key into ~/.ssh/known_hosts but RSA. Secondly, when I had already connect ssh client, it have created ecdsa-sha2-nistp521 entry, then dolphin don't detect it, try RSA and informe the user about key change error. Thirdly, don't ask to replace this key. Cheers, Reproducible: Always
Hello, I've just tested it. libssh saved the ecdsa-sha2-nistp256 key to my known_hosts file. Which version of libssh are you using? Please report a bug upstream and tell us how to reproduce it! https://red.libssh.org/ > Thirdly, don't ask to replace this key. This will never be added. It is a security feature that you need to delete the key in the known_hosts file. Otherwise people do not think if something bad happpend!
Hello, It's because your ssh server is configured with default key lenght, try: ssh-keygen -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key -b 521 -N '' ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key -b 4096 -N '' on openssh server. I use libssh 0.6.3 Cheers,
This is not an issue in kio_sftp. Please open a bug at https://red.libssh.org/ Thanks!
