Manage SSH client and server via Puppet
- Exported resources for host keys management
- puppetlabs/stdlib
Since version 2.0.0 only non-default values are written to both, client and server, configuration files.
Multiple occurances of one config key (e.g. sshd should be listening on port 22 and 2222) should be passed as an array.
options => {
Port => [22, 2222],
}
This is working for both, client and server
Host keys will be collected and distributed
include ssh
or
class { 'ssh':
server_options => {
'Match User www-data' => {
'ChrootDirectory' => '%h',
'ForceCommand' => 'internal-sftp',
'PasswordAuthentication' => 'yes',
'AllowTcpForwarding' => 'no',
'X11Forwarding' => 'no',
},
Port => [22, 2222, 2288],
},
client_options => {
'Host *.amazonaws.com' => {
'User' => 'ec2-user',
},
},
}
Collected host keys from servers will be written to known_hosts
include ssh::client
or
class { 'ssh::client':
options => {
'Host short' => {
'User' => 'my-user',
'HostName' => 'extreme.long.and.complicated.hostname.domain.tld',
},
'Host *' => {
'User' => 'andromeda',
'UserKnownHostsFile' => '/dev/null',
},
},
}
Host keys will be collected for client distribution unless storeconfigs_enabled => false
include ssh::server
or
class { 'ssh::server':
storeconfigs_enabled => false,
options => {
'Match User www-data' => {
'ChrootDirectory' => '%h',
'ForceCommand' => 'internal-sftp',
'PasswordAuthentication' => 'yes',
'AllowTcpForwarding' => 'no',
'X11Forwarding' => 'no',
},
'PasswordAuthentication' => 'no',
'PermitRootLogin' => 'no',
'Port' => [22, 2222],
},
}
'Host *' => {
'SendEnv' => 'LANG LC_*',
'HashKnownHosts' => 'yes',
'GSSAPIAuthentication' => 'yes',
}
'ChallengeResponseAuthentication' => 'no',
'X11Forwarding' => 'yes',
'PrintMotd' => 'no',
'AcceptEnv' => 'LANG LC_*',
'Subsystem' => 'sftp /usr/lib/openssh/sftp-server',
'UsePAM' => 'yes',
Default options will be merged with options passed in. If an option is set both as default and via options parameter, the latter will will win.
The following example will disable X11Forwarding, which is enabled by default:
class { 'ssh::server':
options => {
'X11Forwarding' => 'no',
},
}
Which will lead to the following sshd_config file:
# File is managed by Puppet
ChallengeResponseAuthentication no
X11Forwarding no
PrintMotd no
AcceptEnv LANG LC_*
Subsystem sftp /usr/lib/openssh/sftp-server
UsePAM yes
PasswordAuthentication no
You can define host keys your server will use
ssh::server::host_key {'ssh_host_rsa_key':
private_key_content => '<the private key>',
public_key_content => '<the public key>',
}
Alternately, you could create the host key providing the files, instead of the content:
ssh::server::host_key {'ssh_host_rsa_key':
private_key_source => 'puppet:///mymodule/ssh_host_rsa_key',
public_key_source => 'puppet:///mymodule/ssh_host_rsa_key.pub',
}
Both of these definitions will create /etc/ssh/ssh_host_rsa_key and
/etc/ssh/ssh_host_rsa_key.pub and restart sshd daemon.
