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.
