{pve} API Proxy Daemon
======================
include::attributes.txt[]
endif::manvolnum[]

This daemon exposes the whole {pve} API on TCP port 8006 using
HTTPS. It runs as user 'www-data' and has very limited permissions.
Operation requiring more permissions are forwarded to the local
'pvedaemon'.

Requests targeted for other nodes are automatically forwarded to those
nodes. This means that you can manage your whole cluster by connecting
to a single {pve} node.

Host based Access Control
-------------------------

It is possible to configure "apache2" like access control
lists. Values are read from file '/etc/default/pveproxy'. For example:

----
ALLOW_FROM="10.0.0.1-10.0.0.5,192.168.0.0/22"
DENY_FROM="all"
POLICY="allow"
----

IP addresses can be specified using any syntax understood by `Net::IP`. The
name 'all' is an alias for '0/0'.

The default policy is 'allow'.

|===========================================================
| Match                      | POLICY=deny | POLICY=allow
| Match Allow only           | allow       | allow
| Match Deny only            | deny        | deny
| No match                   | deny        | allow
| Match Both Allow & Deny    | deny        | allow
|===========================================================


SSL Cipher Suite
----------------

You can define the cipher list in '/etc/default/pveproxy', for example

 CIPHERS="HIGH:MEDIUM:!aNULL:!MD5"

Above is the default. See the ciphers(1) man page from the openssl
package for a list of all available options.


Diffie-Hellman Parameters
-------------------------

You can define the used Diffie-Hellman parameters in
'/etc/default/pveproxy' by setting `DHPARAMS` to the path of a file
containing DH parameters in PEM format, for example

 DHPARAMS="/path/to/dhparams.pem"

If this option is not set, the built-in 'skip2048' parameters will be
used.

NOTE: DH parameters are only used if a cipher suite utilizing the DH key
exchange algorithm is negotiated.
