## Network
# Port is not commented out, as it is needed by the example startup
# scripts. Well, the default will not likely change.

# ResolveClientHostName yes
# RequireReverseMapping no
# MaxBroadcastsPerSecond 0
# MaxBroadcastsPerSecond 1
# NoDelay no

## Crypto
# Ciphers AnyCipher
# Ciphers AnyStdCipher
# Following includes "none" 'cipher':
# Ciphers AnyStd
#

# MACs AnyStdMAC
# Following includes "none" 'mac':

#
# RekeyIntervalSeconds 3600
# In order to maximize crypto hardware utilization,
# on z/OS we'll accept only 3des-cbc and hmac-sha1 by default
Ciphers 3des-cbc
MACs hmac-sha1
## Crypto Hardware
# UseCryptoHardware specifies whether hardware support is wanted for certain
# algorithms. The support levels are
# no do not use crypto hardware
# yes use crypto hardware if available
# must use crypto hardware, do not fall back to software
#
# The level may be given alone as a default for all algorithms or
# together with an algorithm. The algorithm names that may
# be used are:
# rng random number generator
# sha1 SHA1 digest algorithm
# 3des Triple DES
# dh Diffie-Hellman
# rsa RSA
#
# UseCryptoHardware is a comma-delimited list of algorithm:support level
# pairs. It may start with a sole support level
#
# E.g. Must have support for 3des and sha1, all other should use software
# UseCryptoHardware no,3des:must,sha1:must
#
# UseCryptoHardware yes
#
# To enable FIPS certification, use
# Ciphers 3des-cbc,aes128-cbc
# MACs hmac-sha1
# UseCryptoHardware must
#
UseCryptoHardware yes,aes:no
## User
# PrintMotd yes
# CheckMail yes
# StrictModes no
# Specifies 1 hour (you can also use 'w' for week, 'd' for day, 'm' for
# minute, 's' for seconds)
# IdleTimeOut 1h
# without specifier, the default number is in seconds
# IdleTimeOut 3600
#
# UserConfigDirectory "%D/.ssh2"
# UserConfigDirectory "/etc/ssh2/auth/%U"
# AuthorizationFile authorization
# This variable is set here, because by default it is empty, and so no
# variables can be set. Because of that, we set a few common ones here.

#
# Ignoring certain restrictions during user login: password expiration
# on z/OS.
# Setting this to "yes" will make an authentication during which an expired
# password was changed count as a successful authentication.
# IgnoreLoginRestrictions.PasswordExpiration no
# To enable authentication time password changing (instead of the old
# forced command style), uncomment the following line:
# AuthPassword.ChangePlugin ssh-passwd-plugin
# (this will also be used by the "password" submethod in
# keyboard-interactive).
## Host restrictions
# AllowHosts localhost, example\.com, friendly\.example
#
## Next one matches with, for example, taulu.foobar.com, tuoli.com, but
## not tuoli1.com. Note that you have to input string "\." when you want it
## to match only a literal dot. You also have to escape "," when you
## want to use it in the pattern, because otherwise it is considered a list
## separator.
##
## AllowHosts t..l.\..*
##
## The following matches any numerical IP address (yes, it is cumbersome)
##
## AllowHosts ([[:digit:]]{1\,3}\.){3}[[:digit:]]{1\,3}
##
## Same thing is achieved with the special prefix "\i" in a pattern.
## This means that the pattern is only used to match IP addresses.
##
## Using the above example:
##
## AllowHosts \i.*
##
## You can probably see the difference between the two.
##
## Also, you can use subnet masks, by using prefix "\m"
##
## AllowHosts \m127.0/8
## and
## AllowHosts \m127.0.0.0/24
##
## would match localhost ("127.0.0.1").
##
# DenyHosts evil\.example, aol\.example
# AllowSHosts trusted\.host\.example
# DenySHosts not\.quite\.trusted\.example
# IgnoreRhosts no
# IgnoreRootRHosts no
# (the above, if not set, is defaulted to the value of IgnoreRHosts)
## User restrictions
# User and group names must be in uppercase.
# AllowUsers SJ.*,S[[:digit:]]*,S(JL|AMZA)
# DenyUsers SKUUPPA,WAREZDUDE,31373
# DenyUsers DON@example\.org
# AllowGroups STAFF,USERS
# DenyGroups GUEST,ANONYMOUS
# PermitRootLogin yes
# PermitRootLogin nopwd
## Chrooted environment
# User and group names must be in uppercase.
# ChRootUsers ANONYMOUS,FTP,GUEST
# ChRootGroups SFTP,GUEST
## Subsystem definitions
# Subsystems do not have defaults, so this is needed here (uncommented).
# subsystem-sftp sftp-server
subsystem-sftp /usr/lpp/ssh2/libexec/sft-server-g3
# Also internal SFTP subsystem can be used.
# subsystem-sftp internal://sftp-server
## Subconfiguration
# There are no default subconfiguration files. When specified the last
# obtained keyword value will prevail. Note that the host-specific files
# are read before the user-specific files.
# User and group names must be in uppercase.
# Following matches (from) any host:
#
# HostSpecificConfig .* /etc/ssh2/subconfig/host_ext.example
#
# Following matches to subnet mask:
#
# HostSpecificConfig \m192.168.0.0/16 /etc/ssh2/subconfig/host_int.example
#
# Following matches to users from ssh.com that have two character
# username or username is SJL and belong to group WHEEL or WHEEL[0-9]:
#
# UserSpecificConfig (..|SJL)%WHEEL[[:digit:]]?@ssh\.com
# /etc/ssh2/subconfig/user.example
#
# Following matches to the user ANONYMOUS from any host:
#
# UserSpecificConfig ANONYMOUS@.* /etc/ssh2/subconfig/anonymous.example
