unifi_direct fails to connect #74657

Closed siyuan-nz closed 2 years ago

siyuan-nz commented 2 years ago

The problem

unifi_direct fails to connect to the Unifi AP over ssh because the updated ssh client no longer accepts ssh-rsa and ssh-dss. Since for years Ubiquiti fails to update dropbear with support for newer key algorithms, the only workaround I can find is by changing self.ssh = pxssh.pxssh() to self.ssh = pxssh.pxssh(options={"HostKeyAlgorithms": "ssh-rsa"}) in device_tracker.py

Could this be related to PR# #74551 - "Python 3.10 ssl cipher defaults in HA 2022.7.0 break the Elk M1 integration"?

siyuan-nz commented 2 years ago

I don't think that's related, if you attempt to ssh from HA to the UniFi AP, you'd see the following error:

$ ssh ubnt@unifi.home.lan
Unable to negotiate with 192.168.9.2 port 22: no matching host key type found. Their offer: ssh-rsa,ssh-dss
