Release notes are available at https://www.openssh.com/txt/release-9.1 9.1 contains fixes for three minor memory safety problems; these have lready been merged to the copy of OpenSSH 9.0 that is in the FreeBSD base system. Some highlights copied from the release notes: Potentially-incompatible changes -------------------------------- * ssh(1), sshd(8): SetEnv directives in ssh_config and sshd_config are now first-match-wins to match other directives. Previously if an environment variable was multiply specified the last set value would have been used. bz3438 * ssh-keygen(8): ssh-keygen -A (generate all default host key types) will no longer generate DSA keys, as these are insecure and have not been used by default for some years. New features ------------ * ssh(1), sshd(8): add a RequiredRSASize directive to set a minimum RSA key length. Keys below this length will be ignored for user authentication and for host authentication in sshd(8). * sftp-server(8): add a "users-groups-by-id@openssh.com" extension request that allows the client to obtain user/group names that correspond to a set of uids/gids. * sftp(1): use "users-groups-by-id@openssh.com" sftp-server extension (when available) to fill in user/group names for directory listings. * sftp-server(8): support the "home-directory" extension request defined in draft-ietf-secsh-filexfer-extensions-00. This overlaps a bit with the existing "expand-path@openssh.com", but some other clients support it. * ssh-keygen(1), sshd(8): allow certificate validity intervals, sshsig verification times and authorized_keys expiry-time options to accept dates in the UTC time zone in addition to the default of interpreting them in the system time zone. YYYYMMDD and YYMMDDHHMM[SS] dates/times will be interpreted as UTC if suffixed with a 'Z' character. Also allow certificate validity intervals to be specified in raw seconds-since-epoch as hex value, e.g. -V 0x1234:0x4567890. This is intended for use by regress tests and other tools that call ssh-keygen as part of a CA workflow. bz3468 * sftp(1): allow arguments to the sftp -D option, e.g. sftp -D "/usr/libexec/sftp-server -el debug3" * ssh-keygen(1): allow the existing -U (use agent) flag to work with "-Y sign" operations, where it will be interpreted to require that the private keys is hosted in an agent; bz3429 MFC after: 2 weeks Relnotes: Yes Sponsored by: The FreeBSD Foundation

|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
is used by
|
|
.Xr ssh 1 ,
|
|
.Xr ssh-agent 1 ,
|
|
and
|
|
.Xr ssh-keygen 1
|
|
to access keys provided by a FIDO authenticator.
|
|
.Pp
|
|
.Nm
|
|
is not intended to be invoked directly by the user.
|
|
.Pp
|
|
A single option is supported:
|
|
.Bl -tag -width Ds
|
|
.It Fl v
|
|
Verbose mode.
|
|
Causes
|
|
.Nm
|
|
to print debugging messages about its progress.
|
|
This is helpful in debugging problems.
|
|
Multiple
|
|
.Fl v
|
|
options increase the verbosity.
|
|
The maximum is 3.

.Pp
|

Note that
|
|
.Xr ssh 1 ,
|
|
.Xr ssh-agent 1 ,
|
|
and
|
|
.Xr ssh-keygen 1
|
|
will automatically pass the
|
|
.Fl v
|
|
flag to
|
|
.Nm
|
|
when they have themselves been placed in debug mode.
