Seeing this available in the server, something I'd somehow missed, led
me to test it out.
Not a regression but an existing issue (seen in 8.3p1), unknown if bug
or comprehension issue but reporting now to fix either docs or code
sshd -T | grep -i '^PubkeyAcceptedKeyTypes'
pubkeyacceptedkeytypes ssh-ed25519-cert-v01 at openssh.com,ecdsa-sha2-nistp256-cert-v01 at openssh.com,ecdsa-sha2-nistp384-cert-v01 at openssh.com,ecdsa-sha2-nistp521-cert-v01 at openssh.com,sk-ssh-ed25519-cert-v01 at openssh.com,sk-ecdsa-sha2-nistp256-cert-v01 at openssh.com,rsa-sha2-512-cert-v01 at openssh.com,rsa-sha2-256-cert-v01 at openssh.com,ssh-rsa-cert-v01 at openssh.com,ssh-ed25519,ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,sk-ssh-ed25519 at openssh.com,sk-ecdsa-sha2-nistp256 at openssh.com,rsa-sha2-512,rsa-sha2-256
So besides the option not being renamed or duplicated under both names
for compatibility ... the glob removals don't work, and attempts to
remove rsa-sha2-256 explicitly don't work here either. Something seems
to be adding them back in?
