pmgproxy - Proxmox Mail Gateway API Proxy Daemon
|
|
================================================
|
|
endif::manvolnum[]
|
|
|
|
This daemon exposes the whole {pmg} API on TCP port 8006 using
|
|
HTTPS. It runs as user `www-data` and has very limited permissions.
|
|
Operations requiring more permissions are forwarded to the local
|
|
`pmgdaemon`.
|
|
|
|
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 {pmg} node.
|
|
|
|
Alternative HTTPS certificate
|
|
-----------------------------
|
|
|
|
By default, pmgproxy uses the certificate `/etc/pmg/pmg-api.pem` for HTTPS
|
|
connections. This certificate is self signed, and therefore not trusted by
|
|
browsers and operating systems by default. You can simply replace this
|
|
certificate with your own (please include the key inside the '.pem' file).
|
|
|
|
|
|
Host based Access Control
|
|
-------------------------
|
|
|
|
It is possible to configure Apache2-like access control
|
|
lists. Values are read from file `/etc/default/pmgproxy`. 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`.
|
|
|
|
[width="100%",options="header"]
|
|
|===========================================================
|
|
| 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/pmgproxy`, for example
|
|
|
|
CIPHERS="ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256"
|
|
|
|
Above is the default. See the `ciphers(1)` man page from the `openssl`
|
|
package for a list of all available options.
|
|
|
|
The first of these ciphers, available to both the client and the `pmgproxy`,
|
|
will be used.
|
|
|
|
Additionally you can allow the client to choose the cipher from the list above
|
|
by disabling the HONOR_CIPHER_ORDER option in `/etc/default/pmgproxy`:
|
|
|
|
HONOR_CIPHER_ORDER=0
|
|
|
|
|
|
Diffie-Hellman Parameters
|
|
-------------------------
|
|
|
|
You can define the used Diffie-Hellman parameters in
|
|
`/etc/default/pmgproxy` 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.
|
|
|
|
COMPRESSION
|
|
-----------
|
|
|
|
By default `pmgproxy` uses gzip HTTP-level compression for compressible
|
|
content if the client supports it. This can be disabled in `/etc/default/pmgproxy`
|
|
|
|
COMPRESSION=0
