Free net software for linux

net-check package is a pair of simple perl scripts that will monitor and report on your internet connectivity.

The scripts came about when my DSL provider repeatedly dropped the connections on a machine that was used exclusively as a dial-up gateway.

In addition, since I am spending $50 a month for my internet connection, I want to make sure I get what I paid for.

A Sample:

To: user@isp.net
Subject: Automated Network Checks Report

Last month, there were 64.25 hours of downtime out of 720 possible hours.
(There were only 2692 out of 2880 possible samples made.)
Last months ratio was 0.089 so your bill should be $45.53.

Enhancements:
- With this version i change the number release, the latest 1.7 version now is a 1.1.x.x version, in CHANGELOG you can see where it is.
- Two file fore changelog information:
CHANGELOG is writed by my hand with simple information
CHANGELOG-AUTO is generated from cvs server with detailed change
- In this release we start from the last ex-1.7 version, now 1.1.x.x, and insert new feature like a sistem to generate the network details.
- Some code was added to improve the security of the tool, but now is not complete.

- This release have the same database structure and dont break compatibility with old version.
For any bug/problem or idea please use sourceforce site to notify me.
Thank You to use Net=MGM

net-acct logs network traffic. It provides a daemon (nacctd) that logs all traffic passing through the machine it runs on. Capability is provided to associate traffic to slip/ppp users if you run a slip/ppp server.
You should use this because:
You are providing IP to customers and want to charge them based on the traffic they generate.
You are a statistics freak and want to see how much of your network traffic is for NetNews, FTP, WWW etc.
Enhancements:
- revised docs and Makefile slightly (added -O2 etc)
- increased default hash table size and improved algorithm
- added ICMP masquerading and masq bug fixes
- fixed bug with multiple notdev definitions in naccttab
- added PLIP header entry to naccttab.sample
- fixed disable entry in naccttab from field 8 to 7 for 0.5 compatibility
- fixed problem with promisc devices not being reinitialized on SIGHUP

Net-SSH2 is a SSH 2 protocol interface.

SYNOPSIS

Top
use Net::SSH2;

my $ssh2 = Net::SSH2->new();

$ssh2->connect(example.com) or die;

if ($ssh2->auth_keyboard(fizban)) {
my $chan = $ssh2->channel();
$chan->exec(program);

my $sftp = $ssh2->sftp();
my $fh = $sftp->open(/etc/passwd) or die;
print $_ while < $fh >;
}

Net::SSH2 is a perl interface to the libssh2 (http://www.libssh2.org) library. It supports the SSH2 protocol (there is no support for SSH1) with all of the key exchanges, ciphers, and compression of libssh2.

Unless otherwise indicated, methods return a true value on success and false on failure; use the error method to get extended error information.

The typical order is to create the SSH2 object, set up the connection methods you want to use, call connect, authenticate with one of the auth methods, then create channels on the connection to perform commands.

SDL.NET is a set of object-oriented CLS-compliant .NET bindings for the SDL gaming library. And provides high-level access to audio, keyboard, mouse, joystick, TrueType fonts, various image formats, sound mixing, MPEG-1 movies and 3D hardware via OpenGL, 2D video framebuffer.

Net::Oscar project is a pure Perl implementation of the OSCAR protocol used by ICQ and AIM instant message clients.

Net::DRI is a collection of object oriented Perl modules that provides an abstract and uniform interface to connect to domain name providers, either registries, registrars or an entity at another level.
Thus Net::DRI can be used by a registrar to establish connections with various registries, or by a reseller that needs to connect with its registrar, or by an end client that needs to connect with its provider, be it a registrar or not, without being forced to use the specific interface available from the provider!
Net::DRI can then allow access to functions that were not even available in the native provider interface, such as batch processing. Furthermore, by hiding differences between providers interfaces, an application using Net::DRI for its connections will almost not have to be changed if there is a need to change providers, or if one provider changes the way it operates (new interface, other protocols, and so on...). With this solution, it is easy to adapt to political or technical changes of its registration providers.
Net::DRI implements many transports and protocols: this allows to take into account specifics of various providers. It is an open framework, and it is easy to add new providers, protocols and transports; it also allows to easily handle cases close to a standard but with few differences. Net::DRI handles synchronous providers (ex: through a web site, the answer comes immediately) as well as asynchronous ones (ex: by email, the answer can come many hours after the request).
Net::DRI implements RRP and EPP, which are two IETF standards. It is the only independant and free implementation of these two standards. Everywhere it is possible, Net::DRI standardizes on EPP (for example for return status codes) by translating other cases to EPP.
Net::DRI can handle many providers simultaneously, even if they offer services in the same domain names, through as many simultaneous connections as needed with various protocols and/or transports for the same provider.
Enhancements:
- This release adds full support for .LU as well as updated support for .AT and .BIZ.
- It also adds two new protocols that can be used by anyone, not only registrars: DAS is used by .BE and .EU to query only the availability of a domain name, and Whois (RFC3912) with parsing is provided for .COM, .NET, .ORG, .BIZ, .INFO, .AERO, and .EU.

Net::Pcap is an Interface to pcap(3) LBL packet capture library.

SYNOPSIS

use Net::Pcap;

my $err = ;
my $dev = Net::Pcap::lookupdev($err); # find a device

# open the device for live listening
my $pcap = Net::Pcap::open_live($dev, 1024, 1, 0, $err);

# loop over next 10 packets
Net::Pcap::loop($pcap, 10, &process_packet, "just for the demo");

# close the device
Net::Pcap::close($pcap);

sub process_packet {
my($user_data, $header, $packet) = @_;
# do something ...
}

Net::Pcap is a Perl binding to the LBL pcap(3) library. The README for libpcap describes itself as:

"a system-independent interface for user-level packet capture.
libpcap provides a portable framework for low-level network
monitoring. Applications include network statistics collection,
security monitoring, network debugging, etc."
