Settings

The configuration for Smart-Proxy is held in the config/settings.yml file.

YAML start

The first non-comment line of this file must be three dashes.

---

SSL configuration

The existence of all the three ssl key entries below enables the use of an SSL connections.

NOTE that both client certificates need to be signed by the same CA, which must be in the ssl_ca_file, in order for this to work
see SSL for more information

:ssl_certificate: ssl/certs/fqdn.pem
:ssl_ca_file: ssl/certs/ca.pem
:ssl_private_key: ssl/private_keys/fqdn.key

This is the list of hosts from which the smart proxy will accept connections. If this list is empty then every verified SSL connection is allowed to access the API.

:trusted_hosts:
- foreman.prod.domain
- foreman.dev.domain

Instance attributes

If this entry is present and not false then Smart-Proxy will attempt to disconnect itself from the controlling terminal and daemonize itself.

:daemon: true

The port listened to by the proxy. If this is not present then the default Sinatra port of 4567 is used.

:port: 8443

TFTP section

Activate the TFTP management module within the Smart-Proxy instance.

The tftproot value is directory into which tftp files are copied and then served from. The tftp daemon will also be expected to chroot to this location. This component is only supported in the Unix environment

:tftp: true
:tftproot: /var/lib/tftpboot

NOTE: the foreman proxy user must have read/write access to the tftpboot/pxelinux.cfg and tftpboot/boot directories.

DNS section

Activate the DNS management module within the Smart-Proxy instance.

The DNS module can manipulate any DNS server that complies with the ISC Dynamic DNS Update standard and can therefore be used to manage both Microsoft and Bind servers.

The dns_key is used to validate the client request. If it is not present then the update operation is performed without peer verification, (not recommended.)
The dns_server option is used if the Smart-Proxy is not located on the same physical host as the DNS server. If it is not specified then localhost is presumed.

:dns: true
:dns_key: /home/proxy/keys/Kapi.+157+47848.private
:dns_server: dnsserver.site.domain.com

NOTE: if you use a key, make sure that the foreman proxy account can read that file.

DHCP section

Activate the DHCP management module within the Smart-Proxy instance.

:dhcp: true

If the DHCP server is ISC compliant then set dhcp_vendor to isc. In this case Smart-Proxy must run on the same host as the DHCP server.
If the proxy is managing a Microsoft DHCP server then set dhcp_vendor to native_ms. Smart-Proxy must then be run on an NT server so as to access the Microsoft native tools, though it does not have to be the same machine as the DHCP server. More details can be found at Foreman Architecture.
:dhcp_vendor: isc

The DHCP component needs access to the DHCP configuration file as well as the currently allocated leases. The section below shows these values for a RedHat client. In the case of a Smart-Proxy hosted on an Ubuntu machine then these values would be more appropriate: /etc/dhcp3/dhcpd.conf and /var/lib/dhcp3/dhcpd.leases
:dhcp_config: etc/dhcpd.conf
:dhcp_leases: etc/dhcpd.leases

NOTE: Make sure that the foreman proxy account can read both ISC configuration files.

Puppet Certificate Authority section

Activate the Puppet CA management module within the Smart-Proxy instance.

This should only be enabled in the Smart-Proxy that is hosted on the machine responsible for providing certificates to your puppet clients. You would expect to see a directory /var/lib/puppet/ssl/ca on such a host.

:puppetca: true

Sudo access to the proxy is required - in your sudoers file ensure you have the following lines:

foreman-proxy ALL = NOPASSWD: /usr/sbin/puppetca
Defaults:foreman-proxy !requiretty

Puppet section

Activate the puppet management module within the Smart-Proxy instance.

This should only be enabled in the Smart-Proxy that is hosted on the machine capable of executing puppetrun. This will be a puppetmaster.

:puppet: true

Sudo access to the proxy is required - in your sudoers file ensure you have the following lines:
foreman_proxy ALL = NOPASSWD: /usr/bin/puppetrun

Logging

The proxy's output is captured to the the log_file and may be filtered via the usual unix syslog levels:

  • WARN
  • DEBUG
  • ERROR
  • FATAL
  • INFO
  • UNKNOWN

See Ruby's Logger class for details.

:log_file: /tmp/proxy.log
:log_level: DEBUG
