X-NetStat Professional shows your current Internet and network connections in realtime. These connections are established each time you visit a web page, send an instant message, check your email, or anytime you do network activity that requires you to connect to another computer. They also appear when outside computers attempt to connect to your machine, authorized or not.

Information shown includes local and remote addresses, local and remote ports, the status, the age of the connection, how much bandwidth/traffic the connection is using, and the program EXE behind it. It's kind of like Internet/network radar, and you can even kill unwanted connections.

The Professional edition of X-NetStat offers a ton of additional features geared towards Network Administrators, like a Rules system to set up actions based on network conditions, a comprehensive Network Statistics window displaying information on network interfaces and protocols, a server that lets you access XNS information remotely, a collection of Lookup Tools (TraceRoute, WHOIS, Finger, DNS, Web Search, Server Version, NetBIOS Lookup, Online Tools, etc), a Port Database, Logging capabilities, transmission LED lights, a dockable ViewBar, and many more features.

When you're connected to the Internet, you're sending and receiving information in small units called packets.
A packet contains the addresses of the sender and the recipient along with a portion of data, a request, a command, or almost anything having to do with your connection to the Internet.
But just as with postal mail, not every package that arrives at your computer is one you want to open.
Protoport Personal Firewall examines each data packet sent to or from your computer to see if it meets a set of criteria. The firewall then passes or blocks the packet selectively.
After you download and install the ProtoPort Personal Firewall software, your computer will be protected against hacker attacks.
All network traffic is monitored on the lowest possible level ensuring all unwanted network packets are kept off your computer.
Native support of all popular protocols (ARP, IP, TCP, UDP, ICMP, etc.)
The program can also limit network bandwidth for specified applications, block online ads, block cookies, ActiveX, Flash movies, Java and Visual Basic scripts.

Remote procedure call (RPC) is a technology that allows a computer program to cause a subroutine or procedure to execute in another address space (commonly on another computer on a shared network) without the programmer explicitly coding the details for this remote interaction. That is, the programmer would write essentially the same code whether the subroutine is local to the executing program, or remote. When the software in question is written using object-oriented principles, RPC may be referred to as remote invocation or remote method invocation. All communications is transparent for developer. You need write code like for local object. You don't see differences between local and remote objects.
Routix software develop own RPC technology known as Routix.RPC. This technology based on TCP-transport and XML-packets (messages). Our technology differs from other implementations in the high speed of calls, ease of use, support of callback-objects.
Routix.RPC use strong encryption and intellectual compression of network communications between client and server. If you purchased Routix.RPC with source code - you can simply extend communication protocol by adding your custom data to the packets because Routix.RPC use XML-packets as communication protocol. Routix.RPC can be used in distributed N-tier applications, service-console applications, remote management software.

BigSpeed Secure Socket Library is an ActiveX control that dramatically simplifies and accelerates the development of proprietary communication solutions over the Internet. It implements a flexible message-oriented protocol on top of a single TCP connection. The transfered data are scrambled using on-the-fly 128-bit AES encryption with random session keys, without need of SSL certificates. The security is provided in two different modes: symmetric encryption with shared secret key and asymmetric encryption with 1024-bit public/private keys. Transport level authentication is available with optional digital fingerprints or secret keys. Building a virtual private application network is just a matter of setting the same crypto key on two or more sites.

BigSpeed Secure Socket Library can be used both on client and server side, with centralized management of all connections. Information is exchanged through typed data packets identified by a command code. The library takes care of all low-level tasks: packetizing/depacketizing, compression/decompression, encryption/decryption, sending, receiving, buffer congestion and flow control. There is support for automatic DNS name resolution and SOCKS proxy servers.

BigSpeed Secure Socket Library utilizes an elegant event-driven paradigm for easy integration into Windows applications. A special attention is paid to provide responsive user interface while maintaining maximum bandwidth efficiency. Carefully designed set of properties, methods, and events offers great flexibility to develop innovative communication software. Sample applications for chat, alert messaging, and file transfer are included in Visual Basic 6, Visual Basic .NET, Visual C++ .NET, and Delphi 7.

1. Overview

SwitchSniffer is a program that can scan your switched LAN for up hosts and can reroute and collect all packets without the target users' recognition. It can also detect the ‘arpspoofer’ program running on the network and block user definable sessions like firewall. If you use this program in tandem with any sniffer program, you can capture and see the users’ IDs and passwords on a switched network.


1.1 Features:

-. It can pull and collect all the packets on the LAN.
-. It can scan and show the active hosts on the LAN within a very short time.
-. While spoofing ARP tables, it can act as another gateway (or ip-forwarder) without other users' recognition on the LAN.
-. It can collect and forward packets by selecting inbound, outbound, and both to be sent to the Internet.
-. An ARP table is recovered automatically in a little time (about 30 seconds). But, this program can keep spoofing continuously with a periodic time.
-. Although one or more network interface cards are installed on a computer, this program can scan and spoof by selecting one of NICs.
-. It can get traffic information about the amount of data transferred to and from the internet including I session information.
-. It can detect which computer is running an arpspoofer program on the local network.
-. It can scan all hosts automatically on the network.
-. It has a feature which filters or blocks sessions, local hosts and remote hosts.
-. It can cure arp-cache poisoning.


1.2 Benefits:

-. It can find out the hidden hosts on local area network.
-. It can check out if abnormal hosts are connected on the wireless network.
-. It protect your network from abnormal users.
-. It can check out if there are abnormal packets on the local network.
-. It can view users/passwords, chat sessions and web sessions etc., on the switch network
by other application.
-. You can use the network without blocking of arp-spoofer.
