Release notes are available at https://www.openssh.com/txt/release-9.0 Some highlights: * ssh(1), sshd(8): use the hybrid Streamlined NTRU Prime + x25519 key exchange method by default ("sntrup761x25519-sha512@openssh.com"). The NTRU algorithm is believed to resist attacks enabled by future quantum computers and is paired with the X25519 ECDH key exchange (the previous default) as a backstop against any weaknesses in NTRU Prime that may be discovered in the future. The combination ensures that the hybrid exchange offers at least as good security as the status quo. * sftp-server(8): support the "copy-data" extension to allow server- side copying of files/data, following the design in draft-ietf-secsh-filexfer-extensions-00. bz2948 * sftp(1): add a "cp" command to allow the sftp client to perform server-side file copies. This commit excludes the scp(1) change to use the SFTP protocol by default; that change will immediately follow. MFC after: 1 month Relnotes: Yes Sponsored by: The FreeBSD Foundation

# This is the sshd server system-wide configuration file. See
|
|
# sshd_config(5) for more information.
|
|
|
|
# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin
|
|
|
|
# The strategy used for options in the default sshd_config shipped with
|
|
# OpenSSH is to specify options with their default value where
|
|
# possible, but leave them commented. Uncommented options override the
|
|
# default value.
|
|
|
|
# Note that some of FreeBSD's defaults differ from OpenBSD's, and
|
|
# FreeBSD has a few additional options.
