Atc.Network

Atc.Network is a C# library providing robust and flexible tools for network communication and scanning.

• TcpClient/TcpServer: Establish and manage TCP network connections.

• UdpClient/UdpServer: Establish and manage UDP network connections.

• • IPScanner: A flexible tool to scan a range of IP addresses or a single IP address. It comes with various configuration options such as:
  • ICMP Pinging
  • Host Name Resolution
  • MAC Address Resolution
  • Vendor Identification from MAC Address
  • Port Number Testing (None, Well-Known, Well-Known and Common, All)

Using the TcpClient

A sample reference implementation can be found here

Using the UdpClient and UdpServer

A sample reference implementation can be found here

Using the IPScanner

The IPScanner can scan a range of IPAddresses or just a single IPAddress as specified in the IPScannerConfig.

• If IcmpPing is enabled the result for given IPAddress will contain a PingResult with network quality information.
• If ResolveHostName is enabled the result for given IPAddress will contain the hostname if possible to resolve.
• If ResolveMacAddress is enabled the result for given IPAddress will contain the mac-address if possible to resolve.
• If ResolveVendorFromMacAddress is enabled the result for given IPAddress will contain the vendor name from the mac-address if possible to resolve.
• TreatOpenPortsAsWebServices defines what kind of port numbers should be tested, the options are: None, WellKnown, WellKnownAndCommon, All

Example on ScanRange based on WellKnown port numbers

    var ipScannerConfig = new IPScannerConfig
    {
        IcmpPing = true,
        ResolveHostName = true,
        ResolveMacAddress = true,
        ResolveVendorFromMacAddress = true,
        TreatOpenPortsAsWebServices = IPServicePortExaminationLevel.WellKnown,
    };

    var ipScanner = new IPScanner(ipScannerConfig);
    ipScanner.ProgressReporting += IpScannerOnProgressReporting;

    var ipScanResults = await ipScanner.ScanRange(
        IPAddress.Parse("192.168.0.1"),
        IPAddress.Parse("192.168.0.254"),
        CancellationToken.None);

Example on ScanRange based on specified port numbers

    var ipScannerConfig = new IPScannerConfig
    {
        IcmpPing = true,
        ResolveHostName = true,
        ResolveMacAddress = true,
        ResolveVendorFromMacAddress = true,
        TreatOpenPortsAsWebServices = IPServicePortExaminationLevel.None,
    };

    ipScannerConfig.PortNumbers = new List<ushort> { 21, 80, 8080 };

    var ipScanner = new IPScanner(ipScannerConfig);
    ipScanner.ProgressReporting += IpScannerOnProgressReporting;

    var ipScanResults = await ipScanner.ScanRange(
        IPAddress.Parse("192.168.0.1"),
        IPAddress.Parse("192.168.0.254"),
        CancellationToken.None);

Using the IPPortScan

Example on CanConnectWithTcp

    var ipPortScan = new IPPortScan(IPAddress.Parse("192.168.0.27"));
    var ipPortScanResult = await ipPortScan.CanConnectWithTcp(
        80,
        CancellationToken.None);

Example on CanConnectWithHttp

    var ipPortScan = new IPPortScan(IPAddress.Parse("192.168.0.27"));
    var ipPortScanResult = await ipPortScan.CanConnectWithHttp(
        80,
        CancellationToken.None);
