ipPulse

ipPulse is a Remote Status Monitoring Tool. Use ipPulse to monitor the up/down status of IP connected devices (nodes) on any IP connected network. ipPulse uses a variety of methods, including ping, tcp connects, and SNMP to poll and check the network connectivity of a list of user-defined nodes. ipPulse alerts you to failures using a variety of techniques ranging from audible messages to email and pager notification. Supports a large list of target hosts entered as either hostnames or IP addresses. The list can be imported from a text file. Polls the list on a cyclical basis with full control over the list cycle timing parameters. Supports a primary and secondary test. Supports standard Ping ICMP Echo Requests/Replies and automatically uses UDP High Port Ping under Winsock 2 for failed contacts. Primary test only. TCP Port numbers for TCP connect tests are assignable on a per-node basis. Primary or secondary test. Optionally uses SNMP v1 as a secondary test by requesting MIB2 OID interfaces.ifTable.ifEntry.ifOperStatus for every interface found on the target node. Community names are assignable on a per-node basis. Optional SNMP queries can be made for obtaining more extensive data from the target host. ipPulse includes a number of OID presets and 12 user defined OIDs. Example: you can obtain MAC addresses for every interface from an SNMP enabled host. Multiple alerts and logging. Alert options include beeping your computer, playing a wave file, notifying someone by email, or paging someone using either standard numeric or TAP compatible alphanumeric pagers. Logging options include logging all test results to a text file, logging only errors to a text file, or logging errors to a dynamically created HTML page. Any combination of logging options can be used. Alerts are issued upon failures using user-defined criteria. Changes from a FAIL state to a PASS state can now generate email messages or pager messages.

TrafMeter

TrafMeter is a Windows-based tool providing realtime traffic accounting and monitoring. You can use it to count useful traffic of your computer (it's free!) or use to build the traffic accounting system for all PCs in your office LAN. It makes easy to count custom IP packets and troubleshooting problems saving your efforts as a network administrator. In TrafMeter, you can set unlimited number of filters for captured traffic, defining network packets which are used for tracking/reporting. It supports a creation of rulesets for various monitoring purposes. The rulesets can be used for single hosts, subnets, as well as specific groups of hosts - i.e. all hosts in/not in your LAN, specific IP protocols (ICMP,TCP,UDP,OSPF,etc). In addition, TrafMeter allows TCP/UDP port filtering. It includes real-time presentation of traffic activity via graphical charts. Each filter is represented by a unique color, which allows the webmaster and/or administrator to easily 'see' the Internet connection usage of individual users. TrafMeter supports a tracking of network packets for the different filters, letting you analyze and comment on the monitored traffic (which may include MAC addresses from Ethernet headers and the ToS field from IP headers). TrafMeter allows to track visited websites by its name using HTTP Host Header Logging. Report generation via XML, or to the more common database (Microsoft SQL Server, Oracle, MySQL) is present as well.

Finger is the tool for discovering user information by using well known finger service. To use the finger tool enter the User@)Host in the Finger Input box, and click on the Finger button .The results will be shown in the Finger Response section.Using Finger tool makes possible to get Abuse Address of remote host.For example to get the abuse address of prontomail.com you should type prontomail.com@abuse.net in the finger input section. As a result you will receive abuse@mailcentro.com (for prontomail.com) in the finger response section.
