============================
The following is an alphabetical list of which `ssh_config`_ directives
-Paramiko directly supports (most of which involve the parsing/matching process
-itself). It includes any departures from OpenSSH's implementation, which are
-intentionally very few, and usually to support backwards compatibility with
-Paramiko versions lacking some default parse-related behavior.
-
-See `OpenSSH's own ssh_config docs <ssh_config>`_ for details on the overall
-file format, and the intended meaning of the keywords and values; or check the
-documentation for your Paramiko-using library of choice (e.g. `Fabric`_) to see
-what it honors on its end.
+Paramiko interprets during the parse/lookup process (as above, actual SSH
+connections **do not** reference parsed configs). Departures from `OpenSSH's
+implementation <ssh_config>`_ (e.g. to support backwards compat with older
+Paramiko releases) are included. A keyword by itself means no known departures.
- ``AddressFamily``: used when looking up the local hostname for purposes of
- expanding the ``%l``/``%L`` :ref:`tokens <TOKENS>`.
-
- .. note::
- As with the rest of these keywords, it does **not** apply to actual SSH
- connections (as Paramiko's client classes do not load configs for you).
-
- In fact, OpenSSH itself does not use this setting the way Paramiko does
- (its lookup for ``%l`` does not appear to honor ``AddressFamily``).
-
-- ``CanonicalDomains``: sets the domains used for hostname canonicalization.
-- ``CanonicalizeFallbackLocal``: set to ``no`` to enforce that all looked-up
- names must resolve under one of the ``CanonicalDomains`` - any names which
- don't canonicalize will raise `.CouldNotCanonicalize` (instead of silently
- returning a config containing only global-level config values, as normal).
-- ``CanonicalizeHostname``: as with OpenSSH, when a lookup results in this
- being set to ``yes`` (whether globally or inside a specific block), it
- triggers an attempt to resolve the requested hostname under one of the given
- ``CanonicalDomains``, which if successful will cause Paramiko to re-parse the
- entire config file.
-
- .. note::
- As in OpenSSH, canonicalization is quietly ignored for "deep" hostnames -
- by default, hostnames containing more than one period character. This may
- be controlled with ``CanonicalizeMaxDots``; see below.
-
-- ``CanonicalizeMaxDots``: controls how many period characters may appear in a
- target hostname before canonicalization is disabled.
-- ``Host``: exact matching, full and partial globbing (``*``), negation
- (``!``), multiple (whitespace-delimited) patterns per keyword.
-- ``HostName``: supplies potential values for ``%h`` :ref:`token expansions
- <TOKENS>`.
-- ``IdentityFile``: its ability to be specified multiple times and result in a
- list of values is preserved in our parser. Values for this keyword will
- always be a list of strings, if present.
-- ``LocalForward``: like ``IdentityFile``, results in a list of strings.
-- ``Port``: supplies potential values for ``%p`` :ref:`token expansions
+ expanding the ``%l``/``%L`` :ref:`tokens <TOKENS>` (this is actually a minor
+ value-add on top of OpenSSH, which doesn't actually honor this setting when
+ expanding ``%l``).
+- ``CanonicalDomains``
+- ``CanonicalizeFallbackLocal``: when ``no``, triggers raising of
+ `.CouldNotCanonicalize` for target hostnames which do not successfully
+ canonicalize.
+- ``CanonicalizeHostname``: along with the other ``Canonicaliz*`` settings
+ (sans ``CanonicalizePermittedCNAMEs``, which is not yet implemented), enables
+ hostname canonicalization, insofar as calling `.SSHConfig.lookup` with a
+ given hostname will return a canonicalized copy of the config data, including
+ an updated ``HostName`` value.
+- ``CanonicalizeMaxDots``
+- ``Host``
+- ``HostName``: used in ``%h`` :ref:`token expansion <TOKENS>`
+- ``Port``: supplies potential values for ``%p`` :ref:`token expansion
<TOKENS>`.
- ``ProxyCommand``: see our `.ProxyCommand` class for an easy
way to honor this keyword from a config you've parsed.
- - Supports :ref:`expansion tokens <TOKENS>`.
+ - Honors :ref:`token expansion <TOKENS>`.
- When a lookup would result in an effective ``ProxyCommand none``,
Paramiko (as of 1.x-2.x) strips it from the resulting dict entirely. A
later major version may retain the ``"none"`` marker for clarity's sake.
-- ``RemoteForward``: like ``IdentityFile``, results in a list of strings.
-- ``User``: supplies potential values for ``%u`` :ref:`token expansions
+- ``User``: supplies potential values for ``%u`` :ref:`token expansion
<TOKENS>`.
