		Action< Node >	_OnDisconnect )

inline

Member Function Documentation

◆ AddSubNode()

async Task xeno_rat_server.Node.AddSubNode ( Node subnode )

inline

Adds a subnode to the list of subnodes.

Parameters

subnode The subnode to be added.

Exceptions

ArgumentException Thrown when the subnode's SockType is not equal to 0.

Returns: A task representing the asynchronous operation.

This method adds the specified subnode to the list of subnodes. If the subnode's SockType is not equal to 0, it waits for a response from the subnode and then adds it to the subNodeWait dictionary using the received ID as the key. If no response is received, the subnode is disconnected. If the SockType is equal to 0, the subnode is disconnected without waiting for a response. Finally, the subnode is added to the subNodes list.

Here is the call graph for this function:

◆ AddTempOnDisconnect()

void xeno_rat_server.Node.AddTempOnDisconnect ( Action< Node > function )

inline

Adds a function to the list of actions to be executed when a node is disconnected.

Parameters

function The function to be added to the list.

This method adds the specified function to the list of actions to be executed when a node is disconnected.

Here is the caller graph for this function:

◆ AuthenticateAsync()

async Task< bool > xeno_rat_server.Node.AuthenticateAsync ( int id )

inline

Authenticates the client with the server using a random key exchange and returns a boolean indicating success or failure.

Parameters

id	The unique identifier of the client.

Returns: True if the authentication is successful; otherwise, false.

This method initiates the authentication process by exchanging a random key with the server. If the key exchange is successful, it proceeds to validate the socket type and client ID before completing the authentication. If any step in the process fails, the method returns false.

◆ ByteArrayCompare()

bool xeno_rat_server.Node.ByteArrayCompare	(	byte[]	b1,
		byte[]	b2 )

inlineprivate

Compares two byte arrays and returns true if they are equal; otherwise, false.

Parameters

b1	The first byte array to be compared.
b2	The second byte array to be compared.

Returns: True if the byte arrays are equal; otherwise, false.

This method compares the lengths of the input byte arrays b1 and b2 . If the lengths are not equal, the method returns false. Otherwise, it uses the memcmp function to compare the contents of the byte arrays. The memcmp function returns 0 if the byte arrays are equal, and a non-zero value if they are not equal.

Here is the caller graph for this function:

◆ Connected()

bool xeno_rat_server.Node.Connected ( )

inline

Checks if the socket is connected and returns a boolean value indicating the connection status.

Returns: True if the socket is connected; otherwise, false.

This method checks the connection status of the socket and returns a boolean value indicating whether the socket is connected or not. If an exception occurs during the check, the method returns false.

Here is the caller graph for this function:

◆ CreateSubNodeAsync()

async Task< Node > xeno_rat_server.Node.CreateSubNodeAsync ( int Type )

inline

Creates a sub node asynchronously and returns the created node.

Parameters

Type	The type of the sub node to be created. Must be 1 or 2.

Exceptions

Exception Thrown when the Type is less than 1 or greater than 2.

Returns: The created sub node, or null if creation failed.

This method asynchronously creates a sub node with the specified Type . It generates a random ID for the sub node and sends a request to create the sub node. If the creation is successful, it waits for the sub node to be populated and returns it. If creation fails or the sub node is not populated within 10 seconds, it returns null.

Here is the caller graph for this function:

◆ Disconnect()

async void xeno_rat_server.Node.Disconnect ( )

inline

Sets the isDisposed flag to true and disconnects the socket, disposes resources, and triggers the OnDisconnect event.

This method sets the isDisposed flag to true and disconnects the socket if it is not null using asynchronous operation. It disposes the socket and the OneRecieveAtATime resource. If SockType is 0, it iterates through the subNodes list and calls the Disconnect method for each node with SockType not equal to 1. Finally, it triggers the OnDisconnect event and executes any temporary disconnect actions stored in TempOnDisconnects.

Here is the call graph for this function:

◆ GetByteArray()

inlineprivate

Generates a byte array of the specified size filled with random values.

Parameters

size	The size of the byte array to be generated.

Returns: A byte array of size size filled with random values.

This method creates a new instance of the Random class to generate random values and fills the byte array with these values using the NextBytes method.

Here is the caller graph for this function:

◆ GetIp()

string xeno_rat_server.Node.GetIp ( )

inline

Gets the IP address of the remote endpoint.

Returns: The IP address of the remote endpoint as a string. If the IP address cannot be retrieved, "N/A" is returned.

Here is the caller graph for this function:

◆ GetSocketType()

async Task< int > xeno_rat_server.Node.GetSocketType ( )

inlineprivate

Asynchronously receives a byte array from the socket, converts it to an integer representing the socket type, and returns the result.

Returns: The integer representing the socket type received from the socket.

Exceptions

Exception Thrown when the received byte array is null, indicating a disconnection, in which case the method also calls the Disconnect method and returns -1.

Parameters

b1	The first array of bytes to be compared.
b2	The second array of bytes to be compared.
count	The number of bytes to compare.

Returns

An integer that indicates the relationship between the two arrays:

Less than 0 if the first differing byte in b1 is less than the corresponding byte in b2 .
0 if the contents of both arrays are equal.
Greater than 0 if the first differing byte in b1 is greater than the corresponding byte in b2 .

Parameters

data	The byte array to be sent.

Returns: True if the data was sent successfully; otherwise, false.

Exceptions
