# Tasks for IRC
### Useful info
You can try connect IRC server with
```bash
nc localhost <port>
```
---
### User
Represents a connected IRC client.
| Attribute | Type | Description |
|-----------------|----------|------------------------------------------------|
| `fd` | `int` | TCP s-ocket file descriptor |
| `nick` | `string` | IRC nickname |
| `username` | `string` | Username |
| `realname` | `string` | Real name |
| `buffer` | `string` | Incoming data buffer, accumulates until `\r\n` |
| `authenticated` | `bool` | `true` after correct `PASS` |
| `registered` | `bool` | `true` after `NICK` + `USER` received |
**Registration flow:** `PASS` → authenticated → `NICK` + `USER` → registered → client ready
---
### First stage
- Server starts
- It accepts two params, ./ircserv <port> <password>
- The server accepts one user, user can send messages and we can see from server
- Only 1 poll()
### Second stage
- Server can handle multiple clients simultaneously
### Third stage
- Client has nickname and username
- Client needs password for authenticate
- Client can be regular user or operator (admin)
### Fourth stage
- Client can create/connect to channels
- Client can send message inside channel (only people inside this channel can read)
*It will continue...*
