Ports Search

grepip searches the named input FILE (or standard input if no files are named), for lines containing an IP address matched to the given CIDR. grepip finds IP in any context of a line, while grepcidr only if all line is IP.

Hawk is a web based utility for monitoring and comparing hosts on your network with what is in DNS. Hosts that are answering pings but are not in DNS may be unauthorized, and addresses in DNS which are not answering may be able to be reclaimed. Hawk monitors all hosts on the networks you specify and lets you view them via a web page. Hawk consists of a backend written in Perl that monitors hosts by ICMP pings and writes the status to a mysql database. The frontend is in PHP and lets you select which network to view, and how to view it. This version has several enhancements to the original; including cleaner Perl code, a user-definable string to designate unused addresses that are in DNS, testing that the forward and reverse hostnames match, and the daemon forks one process pre subnet.

Command line interface to Icinga. Features: - Listing of service/host states, check queue or downtimes - Detailed service/host info - Scheduling of service rechecks, acknowledging of problems - Detailed filtering (host(group)/service name, state, passive, acknowledged, etc.) - Mostly nagios-compatible

Nagircbot is an IRC bot that monitors Nagios's status file for changes and announces those in an IRC channel. It can also change the topic of the channel to reflect current status.

IP Stack Integrity Checker Its purpose is to test the stability of an IP Stack and its component stacks (TCP, UDP, ICMP et. al.) It does this be generating random packets of the desired protocol. The packets can have tendencies. ie by default all packets have a 50% chance of having IP Options. The packets are then sent against the target machine to either penetrate its firewall rules or find bugs in the IP stack.

Jnettop is a traffic visualiser, which captures traffic going through the host it is running from and displays streams sorted by bandwidth they use.

Nagstamon is a Nagios status monitor for the desktop. It connects to multiple Nagios, Icinga, Opsview, Centreon, Op5 Monitor/Ninja and Check_MK Multisite monitoring servers and resides in systray or as a floating statusbar at the desktop showing a brief summary of critical, warning, unknown, unreachable and down hosts and services and pops up a detailed status overview when moving the mouse pointer over it. Connecting to displayed hosts and services is easily established by context menu via SSH, RDP and VNC. Users can be notified by sound. Hosts and services can be filtered by category and regular expressions.

Lanmap sits quietly on a network and builds a picture of what it sees.

LG is a Looking Glass written in Perl as a CGI script. It can execute almost all BGP-related commands and do ping and traceroute in routers or relay these queries to other looking glasses. It supports both IPv4 and IPv6 commands, and is tested with Cisco, Zebra and Juniper. It can connect to router using either SSH, telnet or rsh protocol.

LLDP (Link Layer Discovery Protocol) is an industry standard protocol designed to supplant proprietary Link-Layer protocols such as Extreme's EDP (Extreme Discovery Protocol) and CDP (Cisco Discovery Protocol). The goal of LLDP is to provide an inter-vendor compatible mechanism to deliver Link-Layer notifications to adjacent network devices. lldpd implements both reception and sending. It also implements an SNMP subagent for net-snmp to get local and remote LLDP information. The LLDP MIB is partially implemented but the most useful tables are here. lldpd also partially implements LLDP-MED. lldpd supports bridge, vlan and bonding. Bonding need to be done on real physical devices, not on bridges, vlans, etc. However, vlans can be mapped on the bonding device. You can bridge vlan but not add vlans on bridges. More complex setups may give false results.
