## Restconf
Setup a web/reverse-proxy server.
For example, using nginx, install, and edit config file: /etc/nginx/sites-available/default:
```
server {
...
location /restconf {
fastcgi_pass unix:/www-data/fastcgi_restconf.sock;
include fastcgi_params;
}
}
```
Start nginx daemon
```
sudo /etc/init.d/nginx start
```
Start the clixon restconf daemon
```
sudo su -c "/www-data/clixon_restconf -f /usr/local/etc/example.xml " -s /bin/sh www-data

then access using curl or wget:

### Details
The example works by creating a netconf rpc call and sending it to the backend: (see the fib_route_rpc() function in [example_cli.c](example_cli.c)).
The example works by defining an RPC in clixon-example.yang:
```
rpc example {
description "Some example input/output for testing RFC7950 7.14.
RPC simply echoes the input for debugging.";
input {
leaf x {
...
```
In the (example_backend.c)[example_backend.c], a callback is registered (fib_route()) which handles the RPC (this is just dummy data):
In the CLI a netconf rpc call is constructed and sent to the backend: See `example_client_rpc()` in [example_cli.c] CLI plugin.
The clixon backend plugin [example_backend.c] reveives the netconf call and replies. This is made byregistering a callback handling handling the RPC:
```

fib_route(clicon_handle h,

"The domain-name type represents a DNS domain name. The
name SHOULD be fully qualified whenever possible.
Internet domain names are only loosely specified. Section
3.5 of RFC 1034 recommends a syntax (modified in Section
2.1 of RFC 1123). The pattern above is intended to allow
for current practice in domain name use, and some possible
future expansion. It is designed to hold various types of
domain names, including names used for A or AAAA records
(host names) and other records, such as SRV records. Note
that Internet host names have a stricter syntax (described
in RFC 952) than the DNS recommendations in RFCs 1034 and
1123, and that systems that want to store host names in
schema nodes using the domain-name type are recommended to
adhere to this stricter standard to ensure interoperability.
The encoding of DNS names in the DNS protocol is limited
to 255 characters. Since the encoding consists of labels
prefixed by a length bytes and there is a trailing NULL
byte, only 253 characters can appear in the textual dotted
notation.
The description clause of schema nodes using the domain-name
type MUST describe when and how these names are resolved to
IP addresses. Note that the resolution of a domain-name value
may require to query multiple DNS records (e.g., A for IPv4
and AAAA for IPv6). The order of the resolution process and
which DNS record takes precedence can either be defined
explicitly or may depend on the configuration of the
resolver.
Domain-name values use the US-ASCII encoding. Their canonical
format uses lowercase US-ASCII characters. Internationalized
domain names MUST be A-labels as per RFC 5890.";

percent-encoding is removed, and all case-insensitive
characters are set to lowercase except for hexadecimal
digits, which are normalized to uppercase as described in
Section 6.2.2.1.
The purpose of this normalization is to help provide
unique URIs. Note that this normalization is not
sufficient to provide uniqueness. Two URIs that are
textually distinct after this normalization may still be
equivalent.
Objects using the uri type may restrict the schemes that
they permit. For example, 'data:' and 'urn:' schemes
might not be appropriate.
A zero-length URI is not a valid URI. This can be used to

"The date-and-time type is a profile of the ISO 8601
standard for representation of dates and times using the
Gregorian calendar. The profile is defined by the
date-time production in Section 5.6 of RFC 3339.
The date-and-time type is compatible with the dateTime XML
schema type with the following notable exceptions:
(a) The date-and-time type does not allow negative years.
(b) The date-and-time time-offset -00:00 indicates an unknown
time zone (see RFC 3339) while -00:00 and +00:00 and Z
all represent the same time zone in dateTime.
(c) The canonical format (see below) of data-and-time values
differs from the canonical format used by the dateTime XML
schema type, which requires all times to be in UTC using
the time-offset 'Z'.
This type is not equivalent to the DateAndTime textual
convention of the SMIv2 since RFC 3339 uses a different
separator between full-date and full-time and provides
higher resolution of time-secfrac.
The canonical format for date-and-time values with a known time
zone uses a numeric time zone offset that is calculated using
the device's configured known offset to UTC time. A change of
the device's offset to UTC time will cause date-and-time values
to change accordingly. Such changes might happen periodically
in case a server follows automatically daylight saving time
(DST) time zone offset changes. The canonical format for
date-and-time values with an unknown time zone (usually
referring to the notion of local time) uses the time-offset
-00:00.";
