FDSRem

FDSRem is a library to communicate with C&C Renegade servers over RenRem protocol with useful extra features such as keep alive.

Features

• Keep Alive: This feature keeps the connection to RenRem alive and runs a timeout check in the client-side.
  • Keep alive sends the password to server every 20 seconds to keep the connection alive. After 10 failed attempts (server does not acknowledge the password, or library fails to send password) connection status will be set to ConnectionStatus.Connecting, and library will automatically attempt to reconnect.
  • If keep alive closes connection due to a client-side timeout, DisconnectedEvent will raise with DisconnectReason.ClientTimeOut.
  • After another 10 failed attempts while connection status is ConnectionStatus.Connecting, keep alive procedure will end, connection status will be set to ConnectionStatus.Disconnected and connection will need to be restarted manually.
  • If keep alive is disabled, application or service which is using the library will need to perform connectivity check while sending commands to RenRem for cases like connection closure without acknowledging clients.
  • If keep alive is disabled, DisconnectedEvent will never raise with DisconnectReason.ClientTimeOut.
• Automatic Connection Handling: Library will automatically handle and supress connection begin/closure messages.
  • Messages that represent connection closures, which are ** Connection timed out - Bye! ** and ** Server exiting - Connection closed! ** will be automatically handled and suppressed from DataReceivedEvent. Instead, these will be raised as an event via DisconnectedEvent, with DisconnectReason.ServerTimeOut and DisconnectReason.ServerShutdown.
  • Message beginning with Password accepted. will be automatically handled and suppressed from DataReceivedEvent. Instead, this will raise ConnectedEvent. Continuing lines after Password accepted. will be extracted to RenRemClient.MessageOfTheDay property.

Examples

There is an example below of initializing RenRemClient with a host name.

var renremPort = 4849;
var client = new RenRemClient("myserver.com", renremPort);

Alternatively, you can specify a local port number to bind the UdpClient. Every RenRemClient constructor accepts the last parameter as local port optionally.

var renremPort = 4849;
var localPort = 1337;
var client = new RenRemClient("myserver.com", renremPort, localPort);

It is also possible to initialize RenRemClient with an IP address instead.

var renremPort = 4849;
var ipAddress = System.Net.IPAddress.Parse("127.0.0.1");
var client = new RenRemClient(ipAddress, renremPort);

Or an IPEndPoint instead.

var renremPort = 4849;
var ipAddress = System.Net.IPAddress.Parse("127.0.0.1");
var ep = new System.Net.IPEndPoint(ipAddress, renremPort);
var client = new RenRemClient(ep);

To enable Keep Alive feature, you need to set KeepAlive property to true.

client.KeepAlive = true;

• You can start connection to RenRem synchronously using client.Start(), or asynchronously using client.StartAsync() methods.
• You can send lines to RenRem synchronously or asynchronously, using client.Send() or client.SendAsync() methods.
• Disposing RenRemClient forces an immediate closure, and does not raise any events. Use client.Stop() if you want events to raise with a graceful closure.
