Some notable changes, from upstream's release notes: - sshd(8): Remove support for obsolete "host/port" syntax. - ssh(1): When prompting whether to record a new host key, accept the key fingerprint as a synonym for "yes". - ssh-keygen(1): when acting as a CA and signing certificates with an RSA key, default to using the rsa-sha2-512 signature algorithm. - ssh(1), sshd(8), ssh-keygen(1): this release removes the "ssh-rsa" (RSA/SHA1) algorithm from those accepted for certificate signatures. - ssh-sk-helper(8): this is a new binary. It is used by the FIDO/U2F support to provide address-space isolation for token middleware libraries (including the internal one). - ssh(1): this release enables UpdateHostkeys by default subject to some conservative preconditions. - scp(1): this release changes the behaviour of remote to remote copies (e.g. "scp host-a:/path host-b:") to transfer through the local host by default. - scp(1): experimental support for transfers using the SFTP protocol as a replacement for the venerable SCP/RCP protocol that it has traditionally used. Additional integration work is needed to support FIDO/U2F in the base system. Deprecation Notice ------------------ OpenSSH will disable the ssh-rsa signature scheme by default in the next release.

|
.Sh DESCRIPTION
|
|
.Nm
|
|
is used by
|
|
.Xr ssh-agent 1

.Nm
|
|
is not intended to be invoked by the user, but from
|
|
.Xr ssh-agent 1 .
|

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-agent 1
|
|
will automatically pass the
|
|
.Fl v

flag to
|
|
.Nm
|
|
when it has itself been placed in debug mode.
