# Minitel for KittenOS NEO
|
|
This package includes the Minitel service, in apps/svc-minitel.lua, and the net library, in libs/net.lua.
|
|
|
|
## Minitel service
|
|
|
|
The Minitel service provides packet sending and receiving abilities.
|
|
|
|
### Installation
|
|
|
|
1. Place apps/svc-minitel.lua into `NEO Disk/apps/svc-minitel.lua`
|
|
2. Set the preference run.svc-minitel to "yes"
|
|
|
|
## Net library
|
|
|
|
The net library provides an easy way of interacting with the minitel service, and implements higher-level features of the stack.
|
|
|
|
### Installation
|
|
|
|
Place libs/net.lua into `NEO Disk/libs/net.lua`
|
|
|
|
### Usage
|
|
|
|
Due to how KittenOS's security model works, you have to initialise the library in an unusual way:
|
|
|
|
```
|
|
local minitel = neo.requireAccess("x.svc.minitel","minitel daemon access")
|
|
local computer = neo.requireAccess("k.computer","pushing packets")
|
|
local event = require("event")(neo)
|
|
|
|
local net = require("net")(event,computer,minitel)
|
|
```
|
|
|
|
This gives access to the event API, computer API and Minitel service to the net library.
|
|
|
|
### API
|
|
|
|
Being a direct port of the OpenOS version, the API is the same.
|
|
|
|
#### Layer 3
|
|
|
|
*net.genPacketID()* - returns a string of random data
|
|
|
|
*net.usend(host, port, data, pid)* - Sends an unreliable packet to *host* on *port* containing *data*, optionally with the packet ID *pid*.
|
|
|
|
*net.rsend(host, port, data)* - Sends a reliable packet to *host* on *port* containing *data*.
|
|
|
|
#### Layer 4
|
|
|
|
*net.send(host, port, data)* - Sends *data* reliably and in order to *host* on *port*.
|
|
|
|
#### Layer 5
|
|
|
|
*net.open(to,port)* - Establishes a stream to *host* on *port* and returns a stream object
|
|
|
|
*net.listen(port)* - Waits for another node to establish a stream, and returns the stream object.
|
|
|
|
#### Stream objects
|
|
|
|
*stream:write(data)* - Sends *data* to the node at the other end of the stream
|
|
|
|
*stream:read(length)* - Reads data from the stream, up to *length* bytes.
|
|
|
|
*stream:close()* - Ends the stream and prevents further writing.
|
|
|
|
#### Variables
|
|
|
|
*net.mtu = 4096* - The maximum length of the data portion of a packet for *net.send*
|
|
|
|
*net.streamdelay = 60* - The time, in seconds, *net.open* will wait for a response while trying to establish a connection.
|
|
|
|
*net.minport = 32768* - The lowest port *net.listen* will allocate to a new connection.
|
|
|
|
*net.maxport = 65535* - The highest port *net.listen* will allocate to a new connection.
