It's not really used and I'd rather not have it here unless I'm able to actively maintain it properly and build out the web interface. I might re-add it later but for now I'd rather not have it unless anyone's actively using it.

# Oragono Information
|
||
|
||
Here's a bunch of misc info about the Oragono server! This can include questions, plans on
|
||
how I'm going forward, how to properly use features, or why Oragono does/doesn't do
|
||
something.
|
||
|
||
Essentially, this document acts as a braindump about Oragono while we figure out a better
|
||
place to put all this information.
|
||
|
||
|
||
## Accounts and Channels
|
||
|
||
Most IRC servers out there offer IRC account and channel registration through external
|
||
services such as NickServ and ChanServ. In Oragono, we bundle accounts and channel ownership
|
||
in as a native server feature instead!
|
||
|
||
Because there's a lot of aspects of accounts/channels that haven't been specified as native
|
||
commands and all yet, Oragono includes the pseudo-clients NickServ and ChanServ to roughly
|
||
mimic the functionality that other IRCds get from services packages, in a user-facing set
|
||
of commands that's familiar to everyone.
|
||
|
||
The plan is to move more features and functionality (such as channel registration, channel
|
||
permissions and all) over to native commands first and to use the NickServ/ChanServ as
|
||
legacy interfaces to access these functions. However, it's gonna be a while before all of
|
||
this is specified by someone like the IRCv3 WG.
|
||
|
||
|
||
## PROXY
|
||
|
||
The PROXY command, specified by [HAProxy's PROXY v1 specifications](https://www.haproxy.org/download/1.8/doc/proxy-protocol.txt),
|
||
allows someone to setup HAProxy in front of Oragono. This allows them to use HAProxy for
|
||
TLS negotiation (allowing older versions of SSL/TLS than Go's inbuilt TLS support does).
|
||
However, it also allows them to update TLS certificates by updating them with HAProxy,
|
||
rather than relying on our `REHASH` command (which is less-well-tested than I'd like
|
||
right now).
|
||
|
||
This is a toss-up of course – allowing older versions of TLS might be seen as undesired,
|
||
and I wouldn't use the feature myself, but it's useful for real-world installations which
|
||
is why it exists. The command is only allowed from specific hosts which should restrict it
|
||
appropriately.
|
||
|
||
|
||
## Server-to-Server Linking (or Federation)
|
||
|
||
Right now Oragono doesn't support linking multiple servers together. It's certainly planned,
|
||
but it's a fair while away.
|
||
|
||
When I do add S2S linking to Oragono, I want to use it as a testbed for a new sort of
|
||
linking protocol. Mostly, I want a meshy protocol that minimises the effects of netsplits
|
||
while still ensuring that messages get delivered, and preserves the AP nature of IRC
|
||
reliability (in terms of the CAP theorem), which is something that traditional solutions
|
||
based on the Raft protocol don't do.
|
||
|
||
Basically, I'm going to continue working on my [DCMI](https://github.com/DanielOaks/dcmi)
|
||
protocol, get that to a point where I'm happy with it and _then_ start looking at S2S
|
||
linking properly. If anyone is interested in server protocols and wants to look at this with
|
||
me, please feel free to reach out!
|
||
|
||
|
||
## Rehashing
|
||
|
||
Rehashing is reloading the config files and TLS certificates. Of course, you can rehash the
|
||
server by connect, opering-up and using the `/REHASH` command. However, similar to other
|
||
IRCds, you can also make the server rehash by sending an appropriate signal to it!
|
||
|
||
To make the server rehash from the command line, send it a `SIGHUP` signal. In *nix and OSX,
|
||
you can do this by performing the following command:
|
||
|
||
killall -HUP oragono
|
||
|
||
This will make the server rehash its configuration files and TLS certificates, and so can be
|
||
useful if you're automatically updating your TLS certs!
|
||
|
||
|
||
## Rejected Features
|
||
|
||
'Rejected' sounds harsh, but basically these are features I've decided I'm not gonna
|
||
implement in Oragono (at least, not until someone convinces me they're worth doing).
|
||
|
||
### Force/Auto-Join Channels on Connect
|
||
|
||
When a user connects, some IRC servers let you force-join them to a given channel. For
|
||
instance, this could be a channel like `#coolnet` for a network named CoolNet, a lobby
|
||
channel, or something similar.
|
||
|
||
My main objection to having this feature is just that I don't like it that much. It doesn't
|
||
seem nice to forcibly join clients to a channel, and I know I'm always annoyed when networks
|
||
do it to me.
|
||
|
||
To network operators that want to do this, I'd suggest instead mentioning the channel(s) in
|
||
your MOTD so that your users know the channels exist! If they want to join in, they can do
|
||
it from there :)
