towards a common goal. Here we have a much smaller swarm of cooperative
agents and a simpler approach will suffice.
Features
--------
Documentation
=============
> To request features and file bugs, see [the issue tracker][issues].
The following features are _currently implemented and working_:
* The formation of a cluster of nodes, certificate authenticated and
communicating over TLS over TCP.
* Synchronization of a single directory among the cluster nodes.
* Change detection by periodic scanning of the local repository.
* Static configuration of cluster nodes.
* Automatic discovery of cluster nodes. See [discover.go][discover.go]
for the protocol specification. Discovery on the LAN is performed by
broadcasts, Internet wide discovery is performed with the assistance
of a global server.
* Handling of deleted files. Deletes can be propagated or ignored per
client.
* Synchronizing multiple unrelated directory trees by following
symlinks directly below the repository level.
* HTTP GUI.
The following features are _not yet implemented but planned_:
* Change detection by listening to file system notifications instead of
periodic scanning.
The following features are _not implemented but may be implemented_ in
the future:
* Syncing multiple directories from the same syncthing instance.
* Automatic NAT handling via UPNP.
* Conflict resolution. Currently whichever file has the newest
modification time "wins". The correct behavior in the face of
conflicts is open for discussion.

Security
--------
Security is one of the primary project goals. This means that it should
not be possible for an attacker to join a cluster uninvited, and it
should not be possible to extract private information from intercepted
traffic. Currently this is implemented as follows.
All traffic is protected by TLS. To prevent uninvited nodes from joining
a cluster, the certificate fingerprint of each node is compared to a
preset list of acceptable nodes at connection establishment. The
fingerprint is computed as the SHA-1 hash of the certificate and
displayed in BASE32 encoding to form a compact yet convenient string.
Currently SHA-1 is deemed secure against preimage attacks.
Incoming requests for file data are verified to the extent that the
requested file name must exist in the local index and the global model.
Installing
==========
Download the appropriate precompiled binary from the
[releases](https://github.com/calmh/syncthing/releases) page. Untar and
put the `syncthing` binary somewhere convenient in your `$PATH`.
If you are a developer and have Go 1.2 installed you can also install
the latest version from source. `go get` works as expected but builds
a binary without GUI capabilities. Use the included `build.sh` script
without parameters to build a syncthing with GUI.
Usage
=====
Check out the options:
```
$ syncthing --help
Usage:
syncthing [options]
...
```
Run syncthing to let it create it's config directory and certificate:
```
$ syncthing
11:34:13 main.go:85: INFO: Version v0.1-40-gbb0fd87
11:34:13 tls.go:61: OK: Created TLS certificate file
11:34:13 tls.go:67: OK: Created TLS key file
11:34:13 main.go:66: INFO: My ID: NCTBZAAHXR6ZZP3D7SL3DLYFFQERMW4Q
11:34:13 main.go:90: FATAL: No config file
```
Take note of the "My ID: ..." line. Perform the same operation on
another computer to create another node. Take note of that ID as well,
and create a config file `~/.syncthing/syncthing.ini` looking something
like this:
```
[repository]
dir = /Users/jb/Synced
[nodes]
NCTBZAAHXR6ZZP3D7SL3DLYFFQERMW4Q = 172.16.32.1:22000 192.23.34.56:22000
CUGAE43Y5N64CRJU26YFH6MTWPSBLSUL = dynamic
```
This assumes that the first node is reachable on either of the two
addresses listed (perhaps one internal and one port-forwarded external)
and that the other node is not normally reachable from the outside. Save
this config file, identically, to both nodes.
If the nodes are running on the same network, or reachable on port 22000
from the outside world, you can set all addresses to "dynamic" and they
will find each other using automatic discovery. (This discovery,
including port numbers, can be tweaked or disabled using command line
options.)
Start syncthing on both nodes. For the cautious, one side can be set to
be read only.
```
$ syncthing --ro

...
```
You should see the synchronization start and then finish a short while
later. Add nodes to taste.
GUI
---
The web based GUI is disabled per default. To enable and access it you
must start syncthing with the `--gui` command line option, giving a
listen address. For example:
```
$ syncthing --gui 127.0.0.1:8080
```
You then point your browser to the given address.
Excluding Files
---------------
syncthing looks for files named `.stignore` while walking the
repository. The file is expected to contain glob patterns of file names
to ignore. Patterns are matched on file name only and apply to files in
the same directory as the `.stignore` file and in directories lower down
in the hierarchy.
The syncthing documentation is kept on the
[GitHub Wiki](https://github.com/calmh/syncthing/wiki).
