OpenSSH HostBasedAuthentication failing: get_socket_address: getnameinfo 8 failed: Name or service not known when ssh_keysign runs

Server Fault Asked by XLTechie on December 3, 2021

I have two Ubuntu hosts (20.04 and 16.04). Each has a public IP address on eth0, and a private fast network on eth1.
I would like to have ssh HostBasedAuthentication working on the private network side.

I can connect by publickey or password (if enabled), but when trying to use HostBased auth, I get this:

get_socket_address: getnameinfo 8 failed: Name or service not known
get_socket_address: getnameinfo 8 failed: Name or service not known
get_socket_address: getnameinfo 8 failed: Name or service not known
get_socket_address: getnameinfo 8 failed: Name or service not known
get_socket_address: getnameinfo 8 failed: Name or service not known
get_socket_address: getnameinfo 8 failed: Name or service not known
[email protected]: Permission denied (publickey,hostbased).

Results of a foreground sshd -ddd process:

Note that I have checked the finger prints of these failing keys against ssh-keyscan results from the machine in question, and they match.

Edit: Looking at the client debug info below, it appears that get_socket_address: getnameinfo 8 failed: Name or service not known appears whenever ssh_keysign (attempts to) run.

I have tried this from the 20.04 machine to the 16.04 machine, and the other way around–neither works. 20.04 is the client in this description.
