With IPMP, you can assign two or more NICs to a failover group. Each interface is assigned a static test IP address, which is used by Solaris to verify the operational state of the interface.

You can use DPD as an alternative to VPN monitoring. VPN monitoring applies to an individual IPsec VPN, while DPD is configured only in an individual IKE gateway context.

Typically, SNMP uses UDP as its transport protocol. The well known UDP ports for SNMP traffic are 161 (SNMP) and 162 (SNMPTRAP). It can also run over TCP, Ethernet, IPX, and other protocols.

Today, it is still one of the most widely used layer protocols for simple networks. Many networking specialists love it because it offers a consistent and reliable way of monitoring many devices on a network simultaneously.

Nagios basically collects the statistics of your server (either using agent like NRPE, check_mk or via SNMP ) and send the alert to you if the value of the metric is above some predefined threshold.

Explanation: The purpose of ICMP messages is to provide feedback about issues that are related to the processing of IP packets.

Log monitoring tools such as Logwatch and Swatch can certainly help, but the reality is that system logs are only marginally effective at detecting Nmap activity. Special purpose port scan detectors are a more effective approach to detecting Nmap activity. Two common examples are PortSentry and Scanlogd.

In many cases, it is necessary to inspect the contents of the ICMP message and deliver the appropriate error message to the application responsible for transmitting the IP packet that prompted the ICMP message to be sent. ICMP is a network-layer protocol.

Nmap, short for Network Mapper, is a free, open-source tool for vulnerability scanning and network discovery. Network administrators use Nmap to identify what devices are running on their systems, discovering hosts that are available and the services they offer, finding open ports and detecting security risks.

Simple Network Management Protocol (SNMP) Traps are alert messages sent from a remote SNMP-enabled device to a central collector, the "SNMP manager". ... Trap messages are the main form of communication between SNMP monitoring tools - an SNMP Agent and an SNMP Manager.
