3 # This is the sshd server system-wide configuration file. See
4 # sshd_config(5) for more information.
6 # This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin
8 # The strategy used for options in the default sshd_config shipped with
9 # OpenSSH is to specify options with their default value where
10 # possible, but leave them commented. Uncommented options change a
15 #ListenAddress 0.0.0.0
18 # Disable legacy (protocol version 1) support in the server for new
19 # installations. In future the default will change to require explicit
20 # activation of protocol 1
23 # HostKey for protocol version 1
24 #HostKey /etc/ssh/ssh_host_key
25 # HostKeys for protocol version 2
26 #HostKey /etc/ssh/ssh_host_rsa_key

50 # For this to work you will also need host keys in /etc/ssh/ssh_known_hosts
51 #RhostsRSAAuthentication no
52 # similar for protocol version 2
53 #HostbasedAuthentication no
