 wodDHCPServer  License: Freeware

 
  General information wodDHCPServer is a DHCP server component (Dynamic Host Configuration Protocol), available as COM object and ActiveX control. It provides a framework for passing configuration information to hosts on TCP/IP network. wodDHCPServer implements protocol specific infrastructure, allowing you to allocate IP addresses from your address pool, and provide it to requesting clients by your rules. It is configurable by set of objects and events where you can add your code to control component's behavior. How does it work? As described in RFC2131, when clients connect to the network for the first time, they will Announce themselves to the network, waiting for all DHCP servers on the network to send their Offers for possible IP addresses (and other network parameters). Once they receive this information, clients can choose among received offers, and Request the IP address from your server. At any point, based on your decisions, you can Accept client's requests, or just Deny them. At all times, you should keep a database of your address pool, allocations and released done by your server. Each request received from the client gets unique Session object, where session specific data is stored. You will find here client's MAC address (usually your choices will be based on this information), and setup network parameters directly by populating this object information (Hostname, Gateway...). Availability wodDHCPServer can be used from any programming language that supports COM or ActiveX controls. You will find provided samples in VB and VC, but you could also use it in .NET framework, and other languages such as FoxPro.

 Stay Live 2000  License: Freeware

 
  Does your Internet Service Provider drop your dial-up connection after what seems like only nanoseconds of account inactivity? Stay Live 2000 keeps your Internet Dial-Up Connection active and on-line by periodically sending a small TCP/IP packet to one of the many Atomic Clocks maintained by the United States Government. Sending these small packets prevents your ISP from dropping your connection due to inactivity. You may also optionally select to have your computer's internal real-time clock updated each time one of these packets is sent and a response is returned from an NIST Time Server. You can use this utility in one of two ways. Either run your web browser or other Internet software and then launch Stay Live to keep your connection active, or launch Stay Live first to establish an Internet connection and then run your web browser or other software.
