Free network ups tools software for linux

Network UPS Tools is a collection of programs which provide a common interface for monitoring and administering UPS hardware. Network UPS Tools uses a layered approach to connect all of the parts.
Drivers are provided for a wide assortment of equipment. They understand the specific language of each UPS and map it back to a compatibility layer.
This means both an expensive "smart" protocol UPS and a simple "power strip" model can be handled transparently.
This information is cached by the network server upsd, which then answers queries from the clients. upsd contains a number of access control features to limit the abilities of the clients. Only authorized hosts may monitor or control your UPS hardware if you wish.
Since the notion of monitoring over the network is built into the software, you can hang many systems off one large UPS and they will all shut down together.
Clients such as upsmon check on the status of the hardware and do things when necessary. The most important task is shutting down the operating system cleanly before the UPS runs out of power.
Other programs are also provided to log UPS status regularly, monitor status through your web browser, and more.
Enhancements:
- HAL support. IPv6 support.
- Support for many new devices.
- Many driver improvements.
- This release uses automake.

- www ( simple head )
- pop
- nntp
- imap
- irc
- smtp
- Ability to send alerts based on user specified services to:
- pagers
- cell phones
- email
- A frontend that displays a daily report that can be viewed by a web browser or cell phone.
- views specific servers
- views specific services

Network Security Toolkit is a bootable ISO live CD and its based on Fedora Core 2.
The toolkit was designed to provide easy access to best-of-breed Open Source Network Security Applications and should run on most x86 platforms.
The main intent of developing this toolkit was to provide the network security administrator with a comprehensive set of Open Source Network Security Tools. The majority of tools published in the article: Top 75 Security Tools by insecure.org are available in the toolkit.
What we find rather fascinating with NST is that we can transform most x86 systems (Pentium II and above) into a system designed for network traffic analysis, intrusion detection, network packet generation, wireless network monitoring, a virtual system service server, or a sophisticated network/host scanner.
This can all be done without disturbing or modifying any underlying sub-system disk. NST can be up and running on a typical x86 notebook in less than a minute by just rebooting with the NST ISO CD. The notebooks hard disk will not be altered in any way.
NST also makes an excellent tool to help one with all sorts of crash recovery troubleshooting scenarios and situations.
Enhancements:
- We are pleased to announce the latest NST release: v1.5.0. This release is based on Fedora Core 5 using the Linux kernel 2.6.18. Here are some of the highlights for this release: the NST Web User Interface (WUI), has been greatly enhanced and cleaned up; extensive additions to managing and analyzing network packet captures; the ability to setup and manage printers; the ability to easily mount many different supported file system types; the ability to manage the NST as a file server (both NFS and CIFS); the addition of the Inprotect package (a Nessus manager); the addition of the Zabbix package (another network resource monitoring tool - similar to Nagios)....

Network Security Analysis Tool is a fast, stable bulk security scanner designed to audit remote network services and check for versions, security problems, gather information about the servers and the machine, and much more.

A manpage providing extensive information on NSAT has been included in the distribution. It is available after a make install, or just by typing man doc/nsat.8 from this dir. It is suggested that you inform yourself at least about the -v (scan verbosity) option and edit the configuration file. To learn about changes in this version, please consult doc/CHANGES.

New to this version is support for distributed scanning. The manpage describes how to do a distributed scan. Note that distributed scanning in this version is just a preliminary, proof-of-concept, implementation with no guarantees for its security, reliability, or performance.

Check for updated vulnerability lists, config files, etc. from
http://nsat.sourceforge.net

Currently, these are lists of vulnerabilities:

nsat.cgi (CGI scripts)
nsat.conf (configuration)
src/mod/snmp.h (SNMP community names)

Network FIFO project is a network object that provides data transfering tunnel across network in first in/first out manner.

Simply put,

fifo server file is: monotech_fifo.pl
This script require Net::Server::NonBlocking at least 4.1(you can grab from CPAN)

% perl monotech_fifo.pl < address > < port >

and itll show up like this:

[root@WongWai monotech_fifo]# perl monotech_fifo.pl 192.168.3.52 12000
Listen on 192.168.3.52:20005
Listen on 192.168.3.52:12000

12000 is the port in which the fifo resides.
20005 is the port in which backoffice management resides.

--------------------------------------------------

port 20005 in which the management control resides can be accessed by "admin.pl"

% perl admin.pl < address >

for example

perl admin.pl 192.168.3.52

itll show something like this:

message>

where you can type some commands and press enter

the commands are:

message>readers
message>flush

(flush is the command that read all socket buffer of the admin client socket)

to show all reader in the fifo, it is very useful when some reader is connection disconnected by his ISP or readers machine hangs, the fifo will hold his connection forever (It is because the monotech_fifo.pl doesnt set SO_KEEPALIVE and TCP_KEEPALIVE which will be fixed in the future)

and

message>kill_reader[tab]< fifo name >

to kill any connection of < fifo name >

This package is heavily used by my company, so it is likely reliable.

Java Network Stack provides a Java library for research oriented network programming.

Java Network Stack is a library used by the DIMES project to create new internet measurements. It provides a clean API for packet manipulation, send, receive, filter, and analysis. It is a unification of raw socket capabilities, MAC level networkingm, and IPv6 capabilities.
