Advanced Network Monitor 2.0 is an advanced, powerful, and feature rich tool that monitors servers located on your local network and the Internet. Advanced Network Monitor will allow the Administrator to increase the reliability and productivity of your corporate servers.
After problems are found on the monitored servers Advanced Network Monitor will first try to correct the problems. If ANM cannot correct the problems it immediately notifies the Administrator about the problem via e-mail, sms or a network messaging service. Using Advanced Network Monitor the Administrator is aware about the state of their servers at any time.

Advanced Network Monitor allows you to monitor the following servers and protocols:
TCP/IP, Ping, HTTP, FTP, UDP, SMTP, POP3, IMAP, Telnet, NNTP, DNS, Socks Proxy, DHCP, PHP, Event Log, Service State, RAS Server, VB/Java Script, Terminal Service, WINS, Performance Counter, Registry check, NetBIOS, SNMP, LDAP, SNTP, Oracle, MSSQL, Interbase, ODBC, BDE, Disk space, File existence and External Application tests.

Advanced Network Monitor can execute the following Alerts if one of the server tests will fail:
Send WinPopup message, Show Message, Play Sound, Speak alert using TTS, Send email, Write to Event Log, Restart Service, Restart computer, Execute VBScript/Jscript, Execute ODBC/BDE SQL Query, Execute external application, Write To Text file.

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.

Eltima Serial to Ethernet Connector allows you to share up to 255 serial port devices over TCP/IP network turning your computer into low-cost terminal server. As the result, any serial port device connected to COM port could be accessed from anywhere in the world as if it is attached to local PC.
When the attached serial port device sends communication data it will be actually transmitted over TCP/IP network. Such behavior is achieved due to the use of virtual serial port technology which emulates standard COM ports. In that case Windows OS treats virtual serial ports in the same way as real ones therefore you are no longer limited to just two real ports (any number of physical ports you have) per system and may create COM port connections without occupying any real serial port.
Serial to Ethernet Connector provides the ability create several connection types for three main purposes: share serial port for incoming connections (Server), connect serial port to remote host (Client) and share serial port using UDP. Starting from version 4.0 Serial to Ethernet Connector enables you to select data transmission protocol, which will be used for connection: RAW data transmission algorithm or Telnet (RFC 2217) protocol.

The conaito VoIP EVO SDK contains a high performance VoIP conferencing client capable of delivering crystal clear sound even for both low and high-bandwidth users. conaito VoIP EVO users are arranged in a tree-structure where each node is a room/channel where users can talk, send instant messages and share files. More than 40 users can be in each room/channel and participate in a conference while resource usage, both memory-wise and CPU-wise, is still kept at an acceptable level for gaming and other types of resource intensive tasks.

Here is a list of the main features of the conaito VoIP EVO VoIP client:
* VoIP conferencing with crystal clear sound even for both low and high-bandwidth users (Speex Codec)
* Full Duplex - VoIP conferencing solution (multi-user conferences)
* Comes with Windows as well Linux server (running as service).
* Work with DirectSound as well with Windows Audio.
* Remote console server administration (e.g. use telnet to control the server)
* NEW in v2.1! Multiple-Instances support
* Administrator EVO Server API (VoIP EVO Admin COM control) - 2 SDK versions (VoIP EVO Client SDK and VoIP EVO Admin SDK) are available.
* Record conferences to MP3 - Voice conferencing recording (*.mp3 format)

and much more!

Having the above features available makes it simple to develop any type of VoIP-enabled application, like e.g. a teaching tool, live support, chat, meeting tool, a multiplayer game or any other type of application which requires users being able to talk, type messages and send files to each other. For conaito VoIP EVO clients to be able to interact with each other they must connect to a conaito VoIP EVO server which keeps track of where users are located and forwards voice-data packets between clients. The conaito VoIP EVO server can be hosted in both LAN and internet environments.

BEEP protocol is a generic application protocol for connection oriented, asynchronous interactions. It permits simultaneous and independent exchanges within the context of a single application user-identity.
It supports both textual and binary messages.

BEEP peers communicate with MESSAGES over predefined CHANNELS. Messages are generated by application defined PROFILES. Before message is sent, and once message is recieved by the peer, Profile defines parsing to provide necessary information.

MESSAGES
Messages are initiated by application, and are prepared by defined Profile. Corresponding profile awaits on other side to parse the message and provide only necessary information.

CHANNELS
All exchanges occur in the context of a channel -- a binding to a well-defined aspect of the application, such as transport security, user authentication, or data exchange.

PROFILES
Each channel has an associated "profile" that defines the syntax and semantics of messages exchanged. Implicit in the operation of BEEP is the notion of channel management. Except for few profiles defined internally in wodBeep you can define your own profiles: for data exchange, tuning parameters etc...

TRANSPORT
A BEEP session is mapped onto an underlying transport service. It can be single TCP connection, but also UDP or any higher level two-way transport service-SMTP arhitecture... wodBeep implements TCP transport for you - you can implement easily any other transport just by implementing IBeepTransport interface!!

The Haxxio UDP Serial Port Redirector is the missing link between devices that speak UDP on your network and are thus "connected" to your PC, via an Ethernet port (specifically UDP over IP) and Windows applications on the PC that can only talk to a serial port. Most applications for the Redirector are based on one of

(a) Replacing a simple serial connection, either RS232 or RS485, with a network connection, thus simplifying the connection and removing the cable length barrier, up to the point of crossing the planet.

(b) Requiring to communicate RS232 over a wireless connection between either PCs, or PCs and terminal servers - Wireless ethernet is much cheaper and more available than wireless RS232. Examples

(c) Enabling a group of PCs and/or other devices to all communicate with each other. This can be arranged by having all the devices broadcast their messages, and by using the UDP Redirector on on one or more PCs, these PCs can also be part of this communicating group.
