Free netwhistler software for linux

NetWhistler 2.6 is a easy to use Network monitoring software that offers integrated fault and performance management functionality.
Mila NetWhistler project auto-detects networks and presents them on graphical maps, which reflect up-to-the-minute device and host status. It includes powerful diagnostic tools including ping, main services (ftp, ssh, smtp, pop3, http) monitoring, portscan, email alerts, network discovery, SNMP tools (MIB browser and Trap Console for incoming SNMP traps from any SNMP-enabled device in the network ).
NetWhistler 2.6 can automatically scan a network in search of non-SNMP and SNMP-enabled devices that you want to manage in your network. Scanning parameters ( network address, network mask, SNMP community ) are fully configurable.
Once the discovery operation has been completed, the program displays a map of all devices along with basic information about them such as address, DNS name, MAC address and description. You can find or delete a node on the map, or change node properties. The map can be stored in a local file or in a MySQL database.
Enhancements:
- New features include a Web console and the ability to import and export the database.
- The firewall builder was removed.
- Custom ping, mac-detect, and snmp-results scripts were added.
- Custom node types were added.
- Some bugfixes were made.
