+Important notes gathered through time:
+
+
+# Shorewall duties on our host
+
+- block any access from outside to local ports if not mentionned
+  explicitely in shorewall.
+
+- connect external ports to LXC (dockers has its own means)
+  - This uses ``/var/lib/lxc/*/shorewall`` files
+
+- let mosh connect correctly
+
+- ensure a correct access from Host/LXC/Docker to server's services.
+  For instance, an Host/LXC/Docker should be able to as if it was
+  external: ``curl https://myhostwebsite``. This is called routeback
+  and requires some special rules.
+
+
+# Shorewall restarting and cache
+
+Some process in shorewall seems to be using cache in some ways in
+recent version that implies that it won't take actions if files are
+not changed. A simple 'touch FILE' seems to be enough. Notice the
+'Compiling' lines appearing in ``shorewall restart``.
+
+It's always good to double-check in ``iptables -nL`` that some rules
+actually seem to match your intention.
+
+Don't forget that ``iptables-save`` is probably the best way to get
+the full rules printed on stdout.
+
+
+# Debian, ovh kernels and iptables-nft
+
+Starting from Debian10, iptables by default uses iptables-nft... which
+works well with default debian kernel. OVH kernels DO NOT provide
+necessary kernel and we must:
+
+    update-alternatives --set iptables /usr/sbin/iptables-legacy
+
+Note that transition is a little tricky because BOTH ways can have
+their tables simultaneously. Use ``iptables-nft -nL`` and
+``iptables-legacy -nL`` to check.
+
+For now, we had little success to properly have the ``nft`` version
+working properly on debian kernel. So even on debian kernel, we switch
+here to iptables-legacy if on debian system.
+
+
+# Interaction with docker's iptables rules
+
+This is configured in ``shorewall.conf``, thanks to a simple::
+
+    DOCKER=Yes
+
+
+# Route back
+
+Be sure to check in /var/lib/lxc/*/shorewall definitions, they
+must include special stances (see in next section).
+
+On the side of shorewall, all network interface should be declared in
+``/etc/shorewall/interfaces``.
+
+
+# lxc ``shorewall`` files
+
+Prefer the usage of ``ports`` files. If you insist on having a better
+control of rules per LXC, you can use ``shorewall`` files.
+
+They should be located in /var/lib/lxc/*/shorewall. This is a standard
+redirection from external host port 10022 to lxc's port 22, on port
+tcp::
+
+    DNAT     net     lan:%%IP%%:22   tcp 10022
+    #DNAT     net     lan:%%IP%%:22   udp 10022
+
+Routeback (access of the same service from Host/LXC/Docker on the external
+address) is given by these additional rules::
+
+    DNAT     lan     lan:www:80     tcp    80    -  %%HOST_INTERNET_IP%%
+    DNAT     lan     lan:www:443    tcp    443   -  %%HOST_INTERNET_IP%%
+
+    DNAT     fw     lan:www:80     tcp    80    -  %%HOST_INTERNET_IP%%
+    DNAT     fw     lan:www:443    tcp    443   -  %%HOST_INTERNET_IP%%
+
+
+# lxc ``ports`` files
+
+They should be located in /var/lib/lxc/*/ports. This is a standard
+redirection from external host port 10022 to lxc's port 22, on both
+tcp and udp::
+
+   10022:22    ## Normal port
+   # 10023:23  ## This is commented !

+
+* Updating the charm to a new version
+
+We are using official image. Latest tags usually.
+
+** Test new version
+
+Rocket.chat has a powerfull and working database update mecanism that
+will take care of migrating database on startup.
+
+*** Get latest available versions
+
+You can double-check available candidate for official images like this:
+
+#+begin_src sh
+docker-tags-fetch rocketchat/rocket.chat -l 15 -f "^[0-9]+\.[0-9]+\.[0-9]+$" | sort -rV
+#+end_src
+
+Check/Choose the version you want to test.
+
+*** Modify your own =compose.yml=
+
+By adding these 2 lines in your rocket chat service:
+
+#+begin_src yaml
+  docker-compose:
+    image: rocketchat/rocket.chat:X.Y.Z
+#+end_src
+
+Replace X.Y.Z by the target version you want to test.
+
+Launch =compose up=.
+
+Be ready to wait a few minutes after =compose up= finished before the
+service to be available: rocketchat is expected to take some time to
+migrate.
+
+
+** Change the current charm to include new version
+
+To prepare the commit for next version, you can run the following
+on the repository you'll use to push the new commit.
+
+#+begin_src sh
+BASENAME=rocketchat/rocket.chat
+VERSION=$(docker-tags-fetch "$BASENAME" -l 15 -f "^[0-9]+\.[0-9]+\.[0-9]+$" | sort -rV | head -n 1)
+echo Last version of rocket chat: $VERSION
+docker pull rocketchat/rocket.chat:"$VERSION" &&

+** Adding new keys for backup
+
+This can be done through the admin accounts configured in =compose.yml=.

+
+#+begin_example
+$ ssh myadmin@$RSYNC_BACKUP_TARGET ssh-key ls
+$ ssh myadmin@$RSYNC_BACKUP_TARGET ssh-key add "ssh-rsa AAA...Jdhwhv rsync@sourcelabel"
+$ ssh myadmin@$RSYNC_BACKUP_TARGET ssh-key ls
+..Jdhwhv sourcelabel
+$ ssh myadmin@$RSYNC_BACKUP_TARGET ssh-key rm sourcelabel
+$ ssh myadmin@$RSYNC_BACKUP_TARGET ssh-key ls
+$
+#+end_example
+
+** Requesting a recover only key
+
+*** as an admin
+
+As an admin, by requesting a recover-only key on an ident that you
+own, you are allowed to read (and only read) the content of the given
+ident. This will allow you to give the credentials to any new host to
+have a direct read access so-as to deploy the backup on a new host.
+
+#+begin_example
+$ ssh myadmin@$RSYNC_BACKUP_TARGET ssh-key request-recovery-key myident > /tmp/private_key
+$ chmod 500 /tmp/private_key
+$ rsync -e "ssh -p 22 -i /tmp/private_key -l rsync" \
+      -azvArH --delete --delete-excluded \
+      --partial --partial-dir .rsync-partial \
+      --numeric-ids $RSYNC_BACKUP_TARGET:/var/mirror/myident/etc/ /tmp/etc
+#+end_example
+
+This key will expire after 15 mn of the last recovery.
+
+*** as a standard backup account
+
+With a standard backup account, you can log on as =rsync= user and
+request without any arguments a recovery key. Indeed, every standard
+backup account is tied to one backup identifier only. So the recover
+key received will be for this backup identifier only.
+
+You'll probably want to use the received key from another computer to
+restore the backup for instance.
+
+#+begin_example
+$ ssh rsync@$RSYNC_BACKUP_TARGET request-recovery-key > /tmp/private_key
+$ chmod 500 /tmp/private_key
+$ rsync -e "ssh -p 22 -i /tmp/private_key -l rsync" \
+      -azvArH --delete --delete-excluded \
+      --partial --partial-dir .rsync-partial \
+      --numeric-ids $RSYNC_BACKUP_TARGET:/var/mirror/myident/etc/ /tmp/etc
+#+end_example
+
+
+* Troubleshooting
+
+** Faking access from client
+
+This should work:
+
+#+begin_src sh
+RSYNC_BACKUP_TARGET_IP=172.18.0.2
+rsync -azvA -e "ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no" \
+  /tmp/toto "$RSYNC_BACKUP_TARGET":/var/mirror/client1
+#+end_src
+
+** Direct ssh access should be refused
+
+#+begin_src sh
+RSYNC_BACKUP_TARGET_IP=172.18.0.2
+ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no \
+  "$RSYNC_BACKUP_TARGET"
+#+end_src
+
+** Wrong directory should be refused
+
+#+begin_src sh
+RSYNC_BACKUP_TARGET_IP=172.18.0.2
+rsync -azvA -e "ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no" \
