Free employers monitor email software for linux

Linksys Monitor provides a Linksys logging and dynamic DNS IP update utility.
Linksys Monitor is a POSIX-compliant application used to monitor and react to device activity of Cisco Linksys devices.
Main features:
- logging of all inbound and outbound network connections to a file (with negative filtering capabilities)
- email notification of any inbound and outbound network connection (with negative filtering capabilities)
- IP address updates to DNS services (dynamic DNS) when the device IP address changes
- email notification of IP address changes
- periodic validation and DNS service updates of the device IP address (via Web)
- highly and easily configurable, but with a very good set of default values.
Enhancements:
- Code cleanup and consolidation.
- Fixed a number of bugs related to the parsing of html responses in web IP checks and IP address updates.
- Removed the manner in which the IP address is determined from the logs. This proved too unreliable and caused to many false positives. Now it determines the IP address solely from the web mannner.
- Fixed an issue when running it on a SUSE box (recvfrom() socket call not supported).

The Monitor application, which consists of 2 parts, a MonitorServer (linux daemon) and a MonitorClient (java gui), will enable the user to monitor and log server process, memory, network and cpu information of multiple servers at a time.

The MonitorClient part is written in Java and is able to connect to one or more Servers that are running the MonitorServer part of the Monitor application.

The client will poll the servers at user specified intervals and will provide a graphical representation of the recources (mem, cpu, nic and process information) of one server at a time.

In addition the MonitorClient is able to log the information of all the servers, each server in a different logfile in a coprehesive CSV format.

The MonitorServer is a seperate application written in C++ and linked to omniORB4 to minimize the load it imposes on the server that is beeing monitored. When the MonitorServer is not beeing polled by a MonitorClient it sits idle.

The client will of course run on any platform that supports Java, but the server currently only supports Linux, kernels 2.2, 2.4, 2.6 and possibly (not tested) 2.0 and >2.6.
