The endpoint SSRF check already delegated its private-network classification to surfguard, but called Surfguard.resolve_public_ips directly rather than through RestrictedHTTP::PrivateNetworkGuard -- the hostname-in, address-out shim #241 established as the app's single guarded-outbound entry point and that Opengraph::Fetch resolves through. Route push resolution through the same guard so once-campfire keeps one place that resolves and classifies outbound addresses. Behavior is unchanged: the guard raises Violation when a permitted host resolves only to blocked addresses (previously an empty list -> nil) and propagates Surfguard::Unresolvable for a host that resolves to nothing; both map to a nil endpoint IP, which fails validation and skips delivery. The allowlist, HTTPS/443 constraints, and per-delivery IP pinning are unchanged.
Campfire
Campfire is a web-based chat application. It supports many of the features you'd expect, including:
- Multiple rooms, with access controls
- Direct messages
- File attachments with previews
- Search
- Notifications (via Web Push)
- @mentions
- API, with support for bot integrations
Running your own Campfire instance
Campfire's Docker image contains everything needed for a fully-functional,
single-machine deployment. This includes the web app, background jobs, caching,
file serving, and SSL. You can use our pre-built image at
ghcr.io/basecamp/once-campfire:latest, or build your own from this repo.
Deploying with ONCE
The easiest way to self-host Campfire is with ONCE. It will guide you through the initial set up and then keep your instance up to date automatically.
If you don't already have once installed, run this on the machine you want to run Campfire on:
curl https://get.once.com | sh
once will launch as soon as the install is finished.
Choose Campfire from the list of applications, follow the instructions, and ONCE will take care of the rest.
If you prefer the command line to the dashboard, you can deploy directly:
once deploy ghcr.io/basecamp/once-campfire --host chat.example.com
Deploying with Docker
If you'd rather run the Docker image yourself, you can read more about that in the self-hosting guide.
Tip
When you start Campfire for the first time, you'll be guided through a wizard to create an admin account. The email address that you enter for the admin account will be visible on the sign-in page, it's there so that people have someone to contact if they need help with their account. If that bothers you, put in any email address you want and create yourself a new admin account.
Development
You are welcome - and encouraged - to modify Campfire to your liking. Please see our development guide for how to get Campfire set up for local development.
