# Services

echo services is a suite of pseudo-clients that runs as its own program and links to the network
as a services server. State is **event-sourced** — every change is an appended event, replayed to
rebuild the database.

## The services

| Service | Purpose |
| --- | --- |
| **NickServ** | account registration, grouped nicks, certificates, public keys, vhosts, profiles |
| **ChanServ** | channel founders and access, auto-op, akick, topic and mode locks |
| **OperServ** | network administration, akills, session control |
| **MemoServ** | offline messages between accounts |

## Running

echo services is configured from its own file and connects to the ircd over the server port:

```sh
echo config.toml
```

On the ircd side, the services server must be U-lined and named as the SASL server — see
[Server links](/docs/linking#services).

## Accounts & SASL

Registration and login are covered in [Accounts & SASL](/docs/accounts). SASL is relayed from the
daemon to services mechanism-agnostically, so new mechanisms work without daemon changes.
