## Description
|
||
|
|
|
||
|
|
Creates a Rsync server qube named "sys-rsync" to be a central document
|
||
|
|
store to which other qubes have access. This is a simple tool that allows
|
||
|
|
individual qubes read/write access to the store using Rsync, rather than using
|
||
|
|
`qvm-copy` or `qvm-move`.
|
||
|
|
|
||
|
|
The greatest problem with SSH is that with large file system, it can freeze
|
||
|
|
or be very slow to navigate the directories (not so much with Qrexec as the
|
||
|
|
connection does not go over the network) and chroots need to be configured by
|
||
|
|
the user.
|
||
|
|
|
||
|
|
## Installation
|
||
|
|
|
||
|
|
- Top:
|
||
|
|
```sh
|
||
|
|
qubesctl top.enable sys-rsync
|
||
|
|
qubesctl --targets=tpl-sys-rsync,sys-rsync state.apply
|
||
|
|
qubesctl top.disable sys-rsync
|
||
|
|
```
|
||
|
|
|
||
|
|
- State:
|
||
|
|
<!-- pkg:begin:post-install -->
|
||
|
|
```sh
|
||
|
|
qubesctl state.apply sys-rsync.create
|
||
|
|
qubesctl --skip-dom0 --targets=tpl-sys-rsync state.apply sys-rsync.install
|
||
|
|
qubesctl --skip-dom0 --targets=sys-rsync state.apply sys-rsync.configure
|
||
|
|
```
|
||
|
|
<!-- pkg:end:post-install -->
|
||
|
|
|
||
|
|
Install on the client template:
|
||
|
|
```sh
|
||
|
|
qubesctl --skip-dom0 --targets=TEMPLATE state.apply sys-rsync.install-client
|
||
|
|
```
|
||
|
|
|
||
|
|
The client qube requires the Rsync forwarder service to be enabled:
|
||
|
|
```
|
||
|
|
qvm-features QUBE service.rsync-setup 1
|
||
|
|
```
|
||
|
|
|
||
|
|
## Access Control
|
||
|
|
|
||
|
|
A `qusal.Rsync` service is created to allow use of Rsync over Qrexec. The
|
||
|
|
default policy `asks` if you want to connect with the `sys-rsync` qube.
|
||
|
|
|
||
|
|
If you want to `allow` Rsync between qubes, insert in you user policy file
|
||
|
|
`/etc/qubes/policy.d/30-user.policy` to allow the service using the following
|
||
|
|
format:
|
||
|
|
```qrexecpolicy
|
||
|
|
qusal.Rsync * SOURCE @default allow target=TARGET
|
||
|
|
```
|
||
|
|
|
||
|
|
When the client can change the data on the server, it can also possibly
|
||
|
|
compromise the server or at least make it hold malicious files and propagate
|
||
|
|
the malicious data with client it is connected to.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
### Server
|
||
|
|
|
||
|
|
The default setting is to have a **read/write** store at `/home/user/shared`,
|
||
|
|
and a **read-only** directory at `/home/user/archive`. All the usual Rsync
|
||
|
|
configuration options are available and you can create other shared
|
||
|
|
directories at will. Additional configuration can be made by editing `.conf`
|
||
|
|
files in `/usr/local/etc/rsync.d/*.conf`. Because access appears to come from
|
||
|
|
localhost, host control directives will not work.
|
||
|
|
|
||
|
|
If you have more than one rsync server qube, you can use
|
||
|
|
[bind-dirs](https://www.qubes-os.org/doc/bind-dirs/) to change the available
|
||
|
|
folders on each server qube.
|
||
|
|
|
||
|
|
### Client
|
||
|
|
|
||
|
|
The Rsync connection is available with the socket `localhost:1839`.
|
||
|
|
|
||
|
|
Rsync the server `shared` read/write directory:
|
||
|
|
```sh
|
||
|
|
rsync --port=1839 localhost::shared /LOCAL/PATH/TO/RSYNC
|
||
|
|
```
|
||
|
|
|
||
|
|
Rsync the server `archive` read-only directory:
|
||
|
|
```sh
|
||
|
|
rsync --port=1839 localhost::archive /LOCAL/PATH/TO/RSYNC
|
||
|
|
```
