Open Source Linux Network Monitoring Software - Page 6

A set of Nagios plugins using snmp to monitor hosts and network equipement.

NTM Is a network traffic monitor for Linux (ubuntu, kubuntu, ecc). Characteristics: Integrate with linux NetworkManager; Autodisconnect when a threshold is reached; Day report; Console and Gui interface (gtk); Not need root privilege;

MIB Navigator is a Java-based GUI application for exploring SNMP MIBs and querying hosts running SNMP agents. Rather than providing persistent network monitoring, it serves as a investigative tool. OIDs are represented as nodes in a tree structure.

Yconalyzer is a low-overhead pcap utility that provides a bird's eye view of traffic on a particular TCP port, displaying a distribution of duration, volume and throughput over all connections while being able to narrow down to a connection as well.

WebInject is a tool for automated testing of web applications and web services. It can be used to test system components with HTTP interfaces, as a test harness to create a suite of functional and regression tests, or for service-level monitoring.

pork, oidentd, iplog and ocd

A bandwidth meter, for monitoring internet connection speeds and usage.

PCAP Analyzer is a tool that helps analyzing network traffic captured in a PCAP format (standard of tcpdump). It has extensible Filters in charge of dissecting packets and printing information like throughput or anything that can be analyzed by Filters (e.g. packet loss, reordering, ...). It comes with several built-in Filters but can be expanded by adding custom-made Filters to the classpath. It was developped to help understanding complex network routing problems, where packets could arrive out-of-order, some were lost, or duplicated. Network analysis needed to synchronize capture on a local (destination) and remote (source) computers and display warning messages while recording traffic in PCAP format for offline analysis. PCAPAnalyzer is typically used piped to tcpdump to show warnings on console, with the possibility to replay traffic later, with different Filters.

https://github.com/subhra74/snowflake Snowflake is a graphical SSH client. It has a file browser, terminal emulator, resource/process manager, disk space analyzer, text editor, log viewer and lots of other helpful tools, which makes it easy to work with remote servers. It runs on Linux and Windows. Snowflake has been tested with Ubuntu server, CentOS, RHEL, OpenSUSE, FreeBSD, OpenBSD, NetBSD and HP-UX

Flexible web-based firewall log analyzer, supporting netfilter and ipfilter, ipfw, ipchains, cisco routers and Windows XP system logs, and mysql or postgresql database logs using the iptables ULOG or NFLOG target of netfilter others mapped to the ulogd format with a view. Fully supports IPv6 for database logs, and netfilter and ipfilter system file logs. Also supports Maxmind's GeoIP version 2 location databases. For Linux, FreeBSD, OpenBSD, Solaris, OSX,etc.

Lilith is a logging and access event viewer for Logback, log4j & java.util.logging. It has features comparable to Chainsaw for log4j. This means that it can receive logging events from remote applications using Logback as their logging backend

This software is a very simple network analyzer. When you click the start button, it will send a configurable stream of UDP packets to a host. (The receiving host is then required to echo all the packets back to the sender, which can be easily done via iptables rule under linux). Once the eched packets arrives back to the sender, the analyzer will calculate all the related statistics like, packet loss, jitter throughput etc... NOTE: in order to receive the echo packets you must configure the receiving host to echo the incoming packets. In the next release i will provide another java application that just echo on an UDP port.

Given SNMP-capable routers and switches, sdig can turn an IP address, DNS/WINS host name or a MAC address into a port description. Sdig will run on most any platform that net-snmp supports. It currently compiles on FreeBSD, Linux and Solaris.

Intrusion Block (IBlock) is a small Linux daemon which greps the alertfile of an IDS such as Snort or Suricata and blocks the offender hosts for a given amount of time using iptables.

OpenLLDP is an Open Source implementation of the IEEE standard 802.1AB Link Layer Discovery Protocol (LLDP). The OpenLLDP project aims to provide a comprehensive implementation of IEEE 802.1AB to help foster adoption of the LLDP protocol.

QOS is a monitoring system. It can monitor Cpu, Disk, Memory, etc. on a large number of hosts (300+). It can also monitor web sites, DNS, and other network services, and can generate reports from the collected monitor data.

Using the InterNet Control Message Protocol (ICMP) "ECHO" facility, monitors several hosts, and notify admin if some of them are down.

Netmap can be used to make a graphical representation of the surounding network. It first uses traceroute to make a list of all routers and their interconnections, after which it generates a .dot file. You need the Dotty program to view the graphical rep

Show system and ISDN information on external liquid crystal displays

Autostatus is a network monitoring program for hosts and services. It is designed to be fast and extremely easy to use. It monitors by icmp pings and by attempting TCP connections to specified ports.

The goal of FireStarter is to provide easy to use, yet powerful, graphical tools for setting up, administrating and monitoring firewalls for Linux machines.

Devmon is a device monitoring script which works in tandem with the Xymon (formerly Hobbit)/BigBrother monitoring suites. It queries remote hosts via SNMP, applies user-defined logic and thresholds to the acquired data, and submits status and alarms to a display server

Python module for the libpcap packet capture library, based on the original python libpcap module by Aaron Rhodes.

Bacula-Web is a web based UI mostly written in PHP which provide you a summarized view of your Bacula's backup infrastructure. It obtain his information from your Bacula catalog's database. Latest stable version is available on https://www.bacula-web.org (Bacula-Web 9.5.0 - released on March 18th 2024).

The purpose of this program is to monitor the state of an ADSL or VDSL2 connection. It works with DSL routers using Broadcom chipsets, which have a fully functional telnet interface with access to the Broadcom CLI. It also supports some Thomson/Technicolor routers via their custom CLI, but some of the features of the program are not available for these models. All of the data is obtained from the CLI via telnet. Data is displayed in graphical form, and also can be seen in raw telnet CLI format.
