It is recommended due to security weaknesses in the v1 protocol 11# that sites run only v2 if possible. Support for v1 is provided to help sites 12# with existing ssh v1 clients/servers to transition. 13# Support for v1 may not be available in a future release of Solaris. 14# 15# To enable support for v1 an RSA1 key must be created with ssh-keygen(1). 16# RSA and DSA keys for protocol v2 are created by /etc/init.d/sshd if they 17# do not already exist, RSA1 keys for protocol v1 are not automatically created. 18 19# Uncomment ONLY ONE of the following Protocol statements. 20 21# Only v2 (recommended) 22Protocol 2 23 24# Both v1 and v2 (not recommended) 25#Protocol 2,1 26 27# Only v1 (not recommended) 28#Protocol 1 29 30# Listen port (the IANA registered port number for ssh is 22) 31Port 22 32 33# The default listen address is all interfaces, this may need to be changed 34# if you wish to restrict the interfaces sshd listens on for a multi homed host. 35# Multiple ListenAddress entries are allowed. 36 37# IPv4 only 38#ListenAddress 0.0.0.0 39# IPv4 & IPv6 40ListenAddress :: 41 42# If port forwarding is enabled (default), specify if the server can bind to 43# INADDR_ANY. 44# This allows the local port forwarding to work when connections are received 45# from any remote host. 46GatewayPorts no 47 48# X11 tunneling options 49X11Forwarding yes 50X11DisplayOffset 10 51X11UseLocalhost yes 52 53# The maximum number of concurrent unauthenticated connections to sshd. 54# start:rate:full see sshd(1) for more information. 55# The default is 10 unauthenticated clients. 56#MaxStartups 10:30:60 57 58# Banner to be printed before authentication starts. 59#Banner /etc/issue 60 61# Should sshd print the /etc/motd file and check for mail. 62# On Solaris it is assumed that the login shell will do these (eg /etc/profile). 63PrintMotd no 64 65# KeepAlive specifies whether keep alive messages are sent to the client. 66# See sshd(1) for detailed description of what this means. 67# Note that the client may also be sending keep alive messages to the server. 68KeepAlive yes 69 70# Syslog facility and level 71SyslogFacility auth 72LogLevel info 73 74# 75# Authentication configuration 76# 77 78# Host private key files 79# Must be on a local disk and readable only by the root user (root:sys 600). 80HostKey /etc/ssh/ssh_host_rsa_key 81HostKey /etc/ssh/ssh_host_dsa_key 82 83# Length of the server key 84# Default 768, Minimum 512 85ServerKeyBits 768 86 87# sshd regenerates the key every KeyRegenerationInterval seconds. 88# The key is never stored anywhere except the memory of sshd. 89# The default is 1 hour (3600 seconds). 90KeyRegenerationInterval 3600 91 92# Ensure secure permissions on users .ssh directory. 93StrictModes yes 94 95# Length of time in seconds before a client that hasn't completed 96# authentication is disconnected. 97# Default is 600 seconds. 0 means no time limit. 98LoginGraceTime 600 99 100# Maximum number of retries for authentication 101# Default is 6.
