Please report any bugs you find to the [issue tracker](https://github.com/GLolol/PyLink/issues). Pull requests are open if you'd like to contribute, though new stuff generally goes to the **devel** branch.
You can also find support via our IRC channel at `#PyLink @ irc.overdrivenetworks.com `([webchat][webchatlink]). Ask your questions and be patient for a response.
* By default you'll be on the **master** branch, which contains the latest stable code. This branch is recommended for production networks that don't require new features or intensive bug fixes as they are developed.
* The **devel** branch is where active development goes, and it can be accessed by running `git checkout devel` in your Git tree.
Unofficial Ubuntu packages for PyLink are available via two PPAs for Ubuntu 14.04 LTS (trusty) and above.
Upon installing the `pylink` package, example configuration and docs will be in `/usr/share/doc/pylink/examples` and `/usr/share/doc/pylink/docs` respectively. You can also install a local copy of the [PyLink API reference](https://pylink.github.io/) through the `pylink-doc` package.
1) Rename `example-conf.yml` to `pylink.yml` (or a similarly named `.yml` file) and configure your instance there. Note that the configuration format isn't finalized yet - this means that your configuration may break in an update!
2) Run `pylink` from the command line. PyLink will load its configuration from `pylink.yml` by default, but you can override this by running `pylink` with a config argument (e.g. `pylink mynet.yml`).
- For vHost setting to work, `m_chghost.so` must be loaded. For ident and realname changing support, `m_chgident.so` and `m_chgname.so` must be loaded respectively.
- Supported channel, user, and prefix modes are negotiated on connect, but hotloading modules that change these is not supported. After changing module configuration, it is recommended to SQUIT PyLink to force a protocol renegotiation.
- Note: Both account cloaks (user and oper) and hashed IP cloaks are optionally supported (`HOST_HIDING_STYLE` settings 0 to 3). Make sure you configure PyLink to match your IRCd settings.
- UnrealIRCd 4.x before version 4.0.12 suffers from [bug #4890](https://bugs.unrealircd.org/view.php?id=4890) which causes hostname desyncs on servers not directly linked to PyLink (e.g. `pylink<->serverA<->serverB` creates desynced hostnames on server B). This problem is fixed by upgrading your IRCds.
- Linking to UnrealIRCd 3.2 servers is only possible when using an UnrealIRCd 4.x server as a hub, with topology such as `pylink<->unreal4<->unreal3.2`. We nevertheless encourage you to upgrade so all your IRCds are running the same version.
Support for these IRCds exist, but are not tested as frequently and thoroughly. Bugs should be filed if there are any issues, though they may not always be fixed in a timely fashion.
- Because bircd disallows BURST after ENDBURST for regular servers, U-lines are required for all PyLink servers. Fortunately, wildcards are supported in U-lines, so you can add something along the lines of `U:<your pylink server>:` and `U:*.relay:` (adjust accordingly for your relay server suffix).
- On ircd-ratbox, all known IPs of users will be shown in `/whois`, even if the client is a cloaked relay client: if you're paranoid about this, turn off Relay IP forwarding by setting the `relay_no_ips` option in the ratbox network's `server:` block.
- For KLINE support to work, a `shared{}` block should be added for PyLink on all servers.
Since v1.0, PyLink supports connecting to IRCds as a relay bot and forwarding users back, similar to Janus' Clientbot. This can be useful if the IRCd a network used isn't supported, or if you want to relay certain channels without fully linking with a network.
