# echo services

**echo services** is a Rust services package that links to the echoIRCd daemon over the S2S protocol
as a linked services server — it is *not* built into the daemon. State is **event-sourced**: every
change is an appended event, replayed to rebuild the database.

## Running

echo services is its own binary with its own configuration:

```sh
echo config.toml
```

Only `[uplink]` and `[server]` are required; everything else is optional. The daemon must U-line the
services server and name it as the SASL server — see [Server links](/docs/linking#services). For the
full configuration, see [Running & config](/docs/services-config).

## The services

The standard suite comes up by default; the enabled set is controlled by `[modules] services`.

| Service | Role |
| --- | --- |
| **[NickServ](/docs/nickserv)** | Register and manage your nick/account; log in |
| **[ChanServ](/docs/chanserv)** | Register and manage channels, access, modes, topics |
| **[OperServ](/docs/operserv)** | Network administration, bans/X-lines, SVS commands (operator) |
| **[MemoServ](/docs/memoserv)** | Leave and read offline messages between accounts |
| **[HostServ](/docs/hostserv)** | Virtual host (vhost) requests, offers, and assignment |
| **[BotServ](/docs/botserv)** | Channel bots that speak, moderate, and auto-respond |
| GroupServ | Named account groups (`!group`) for access lists |
| StatServ | Network and per-channel activity statistics |
| InfoServ | Public and operator bulletins / news |
| ReportServ | User abuse reports queued for staff |
| HelpServ | User help-desk ticket queue |
| DiceServ | Dice-expression rolling and calculation |
| DictServ | DICT-protocol dictionary/thesaurus lookups (opt-in) |
| GameServ | Turn-based games (tic-tac-toe, Connect Four, chess) with ranked stats |
| ChanFix | Restore ops to a channel's trusted regulars |
| DebugServ | Internal diagnostic feed of services activity |

The last ten are covered on the [other services](/docs/other-services) page. echo services also runs a
native [anti-abuse engine](/docs/services-security).

## Accounts & SASL

Registration and login (including key-based ECDSA 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.
