Methods

Close

▸ Close(): void

Close closes the connection.

Returns

void

Example

const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
conn.Close();

Defined in

net.ts:56

---

Recv

▸ Recv(N): Uint8Array

Recv receives data from the connection with a timeout. If N is 0, it will read all data sent by the server with 8MB limit. it tries to read until N bytes or timeout is reached.

Parameters

Name	Type
N	number

Returns

Uint8Array

Example

const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
const data = conn.Recv(1024);

Defined in

net.ts:128

---

RecvHex

▸ RecvHex(N): string

RecvHex receives data from the connection with a timeout in hex format. If N is 0,it will read all data sent by the server with 8MB limit.

Parameters

Name	Type
N	number

Returns

string

Example

const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
const data = conn.RecvHex(1024);

Defined in

net.ts:177

---

RecvPartial

▸ RecvPartial(N): Uint8Array

RecvPartial is similar to Recv but it does not perform full read instead it creates a buffer of N bytes and returns whatever is returned by the connection this is usually used when fingerprinting services to get initial bytes from the server.

Parameters

Name	Type
N	number

Returns

Uint8Array

Example

const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
const data = conn.RecvPartial(1024);
log(`Received ${data.length} bytes from the server`)

Defined in

net.ts:145

---

RecvString

▸ RecvString(N): string

RecvString receives data from the connection with a timeout output is returned as a string. If N is 0, it will read all data sent by the server with 8MB limit.

Parameters

Name	Type
N	number

Returns

string

Example

const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
const data = conn.RecvString(1024);

Defined in

net.ts:161

---

Send

▸ Send(data): void

Send sends data to the connection with a timeout.

Parameters

Name	Type
data	string

Returns

void

Example

const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
conn.Send('hello');

Defined in

net.ts:112

---

SendArray

▸ SendArray(data): void

SendArray sends array data to connection

Parameters

Name	Type
data	any

Returns

void

Example

const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
conn.SendArray(['hello', 'world']);

Defined in

net.ts:84

---

SendHex

▸ SendHex(data): void

SendHex sends hex data to connection

Parameters

Name	Type
data	string

Returns

void

Example

const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
conn.SendHex('68656c6c6f');

Defined in

net.ts:98

---

SetTimeout

▸ SetTimeout(value): void

SetTimeout sets read/write timeout for the connection (in seconds).

Parameters

Name	Type
value	number

Returns

void

Example

const net = require('nuclei/net');
const conn = net.Open('tcp', 'acme.com:80');
conn.SetTimeout(10);

Defined in

net.ts:70
