sshd version 7+ problem

[sstefanov]

Hello

After sshd update connection cannot be established. sshd log says: sshd[20593]: Unable to negotiate with ...... port 60335: no matching host key type found. Their offer: ssh-ed25519-cert-v01@openssh.com,ssh-ed25519 [preauth]

Did you try to add HostKeyAlgorithms=+ssh-rsa (or any other host key algorithm) to mountpoint settings?

[sstefanov]

Yes, there is: HostKeyAlgorithms +ssh-rsa in sshd_config System is Debian buster/sid.

HostKeyAlgorithms +ssh-rsa in sshd_config

No. If you want to solve the problem on server side you should add 'ssh-ed25519-cert-v01@openssh.com' or 'ssh-ed25519' support in sshd_config. If you want to solve the problem on client side you can try to enforce easysshfs to use specific HostKeyAlgorithms (e.g. ssh-rsa).

Hello

Still not working!

Here is the server log with debug: https://pastebin.com/JsecNpDN This is sshd_config: https://pastebin.com/aBN1wAtY1

sshd_config contains only rsa, dsa and ecdsa host keys. https://linux-audit.com/using-ed25519-openssh-keys-instead-of-dsa-rsa-ecdsa/

After added ecdsa host key on the server problem is solved! Thank you very much!
