cdist-type__uci(7)
==================
NAME
----
cdist-type__uci - Manage configuration values in UCI
DESCRIPTION
-----------
This cdist type can be used to alter configuration options in OpenWrt's
Unified Configuration Interface (UCI) system.
REQUIRED PARAMETERS
-------------------
value
The value to be set. Can be used multiple times.
This parameter is ignored if ``--state`` is ``absent``.
Due to the way cdist handles arguments, values **must not** contain newline
characters.
Values do not need special quoting for UCI. The only requirement is that the
value is passed to the type as a single shell argument.
OPTIONAL PARAMETERS
-------------------
state
``present`` or ``absent``, defaults to ``present``.
type
If the type should generate an option or a list.
One of: ``option`` or ``list``.
Defaults to auto-detect based on the number of ``--value`` parameters.
BOOLEAN PARAMETERS
------------------
None.
EXAMPLES
--------
.. code-block:: sh
# Set the system hostname
__uci system.@system[0].hostname --value 'OpenWrt'
# Set DHCP option 252: tell DHCP clients to not ask for proxy information.
__uci dhcp.lan.dhcp_option --type list --value '252,"\n"'
# Enable NTP and NTPd (each is applied individually)
__uci system.ntp.enabled --value 1
__uci system.ntp.enable_server --value 1
__uci system.ntp.server --type list \
--value '0.openwrt.pool.ntp.org' \
--value '1.openwrt.pool.ntp.org' \
--value '2.openwrt.pool.ntp.org' \
--value '3.openwrt.pool.ntp.org'

cdist-type__uci_section(7)
==========================
NAME
----
cdist-type__uci_section - Manage configuration sections in UCI
DESCRIPTION
-----------
This cdist type can be used to replace whole configuration sections in OpenWrt's
Unified Configuration Interface (UCI) system.
It can be thought of as syntactic sugar for :strong:`cdist-type__uci`\ (7),
as this type will generate the required `__uci` objects to make the section
contain exactly the options specified using ``--option``.
Since many default UCI sections are unnamed, this type allows to find the
matching section by one of its options using the ``--match`` parameter.
**NOTE:** Options already present on the target and not listed in ``--option``
or ``--list`` will be deleted.
REQUIRED PARAMETERS
-------------------
None.
OPTIONAL PARAMETERS
-------------------
list
An option that is part of a list and should be present in the section (as
part of a list). Lists with multiple options can be expressed by using the
same ``<option>`` repeatedly.
The value to this parameter is a ``<option>=<value>`` string.
``<value>`` does not need special quoting for UCI.
The only requirement is that the value is passed to the type as a single
shell argument.
match
Allows to find a section to "replace" through one of its parameters.
The value to this parameter is a ``<option>=<value>`` string.
option
An option that should be present in the section.
This parameter can be used multiple times to specify multiple options.
The value to this parameter is a ``<option>=<value>`` string.
``<value>`` does not need special quoting for UCI.
The only requirement is that the value is passed to the type as a single
shell argument.
state
``present`` or ``absent``, defaults to ``present``.
type
The type of the section in the format: ``<config>.<section-type>``
BOOLEAN PARAMETERS
------------------
None.
EXAMPLES
--------
.. code-block:: sh
# Configure the dropbear daemon
__uci_section dropbear --type dropbear.dropbear \
--match Port=22 --option Port=22 \
--option PasswordAuth=off \
--option RootPasswordAuth=off
# Define a firewall zone comprised of lan and wlan networks
__uci_section firewall.internal --type firewall.zone \
--option name='internal' \
--list network='lan' \
--list network='wlan' \
--option input='ACCEPT' \
--option output='ACCEPT' \
--option forward='ACCEPT'
# Block SSH access from the guest network
__uci_section firewall.block_ssh_from_guest --type firewall.rule \
--option name='Block-SSH-Access-from-Guest' \
--option src='guest' \
--option proto='tcp' \
--option dest_port='22' \
--option target='REJECT'
# Configure a Wi-Fi access point
__uci_section wireless.default_radio0 --type wireless.wifi-iface \
--option device='radio0' \
--option mode='ap' \
--option network='wlan' \
--option ssid='mywifi' \
--option encryption="psk2' \

* The scanner, 2020-10-29, Hacking Villa Diesbach
** Motivation
- The purpose of cdist is to ensure systems are in a configured state
- If systems reboot into a clean (think: netboot) state they are
stuck in an unconfigured mode
- We can either trigger *from* those machines
- this is what cdist trigger is for
- Or we can regulary *scan* for machines
- This method does not need any modification to standard OS
** How it works
- cdist scan uses the all nodes multicast group ff02::1
- It sends a ping packet there in regular intervals
- This even works in non-IPv6 networks, as all operating systems
are IPv6 capable and usually IPv6 enabled by default
- Link local is always accessible!
- cdist scan receives an answer from all alive hosts
- These results are stored in ~/.cdist/scan/${hostip}
- We record the last_seen date ~/.cdist/scan/${hostip}/last_seen
- After a host is detected, cdist *can* try to configure it
- It saves the result (+/- logging needs to be defined) in
~/.cdist/scan/${hostip}/{config, install}_result
- If logging is saved: maybe in ~/.cdist/scan/${hostip}/{config, install}_log
- Final naming TBD
** Benefits from the scanning approach
- We know when a host is alive/dead
- We can use standard OS w/o trigger customisation
- Only requirement: we can ssh into it
- Can make use f.i. of Alpine Linux w/ ssh keys feeding in
- We can trigger regular reconfiguration
- If alive && last_config_time > 1d -> reconfigure
- Data can be exported to f.i. prometheus
- Record when configured (successfully)
- Record when seen
- Enables configurations in stateless environments

Examples
--------
Here are examples of using alternative __remote_copy and __remote_exec scripts.
All scripts from below are present in cdist sources in `other/examples/remote`
directory.
ssh
~~~
Same as cdist default.
**copy**
Usage: cdist config --remote-copy "/path/to/this/script" target_host
.. code-block:: sh
#echo "$@" | logger -t "cdist-ssh-copy"
scp -o User=root -q $@
**exec**
Usage: cdist config --remote-exec "/path/to/this/script" target_host
.. code-block:: sh
#echo "$@" | logger -t "cdist-ssh-exec"
ssh -o User=root $@
local
~~~~~
This effectively turns remote calling into local calling. Probably most useful
for the unit testing.
**copy**
.. code-block:: sh
code="$(echo "$@" | sed "s|\([[:space:]]\)$__target_host:|\1|g")"
cp -L $code
**exec**
.. code-block:: sh
target_host=$1; shift
echo "$@" | /bin/sh
chroot
~~~~~~
**copy**
Usage: cdist config --remote-copy "/path/to/this/script /path/to/your/chroot" target-id
.. code-block:: sh
log() {
#echo "$@" | logger -t "cdist-chroot-copy"
:

log "target_host: $target_host"
log "chroot: $chroot"
log "$@"

schroot
~~~~~~~
__remote_copy and __remote_exec scripts to run cdist against a chroot on the

**copy**
Use rsync over ssh to copy files. Uses the "--rsync-path" option
to run the remote rsync instance with sudo.
This command assumes your ssh configuration is already set up in ~/.ssh/config.
Usage: cdist config --remote-copy /path/to/this/script target_host
.. code-block:: sh
# For rsync to do the right thing, the source has to end with "/" if it is
# a directory. The below preprocessor loop takes care of that.
# second last argument is the source
source_index=$(($#-1))
index=0
for arg in $@; do
if [ $index -eq 0 ]; then
# reset $@
set --
fi
index=$((index+=1))
if [ $index -eq $source_index -a -d "$arg" ]; then
arg="${arg%/}/"
fi
set -- "$@" "$arg"
done
rsync --copy-links --rsync-path="sudo rsync" -e 'ssh' "$@"
**exec**
Prefixes all remote commands with sudo.
This command assumes your ssh configuration is already set up in ~/.ssh/config.
Usage: cdist config --remote-exec "/path/to/this/script" target_host
.. code-block:: sh
host="$1"; shift
ssh -q "$host" sudo sh -c \""$@"\"
