alived

Alived is a useful software product that allows its clients to send keepalive messages. The simple daemon implementation enables the server to maintain a record of hostname to IP addresses, which proves useful in scenarios where a remote DHCP client generates changes in IP addresses. The central idea behind alived is to facilitate the machine in sending its current IP address to a server. This feature is especially useful for users who cannot regularly monitor or adjust their system settings.

To operate alived, set up the software as a server. You can run it by typing 'alived' in the terminal command line or 'alived -d' to start it as a daemon. You will also need to install the alive client, which should be configured to start up automatically during system boot-ups. To complete the setup, you will need to input the name of your host and the IP or hostname of the server that hosts the daemon.

Alived also comes with an additional feature called 'alookup'. Alookup enables you to obtain the last known IP address of a specific host and the time the server last heard from it.

Recently, the software has been modified to use getopt_long() and follow the GNU standards more closely. These modifications ensure better and standardized performance for the users.

Overall, alived is an excellent software product that provides reliable and essential services to its clients. Its installation and setup is simple and hassle-free, making it a favorite amongst users who require regular updates on their machines' IP addresses.
