Free .net software for linux

The net-tools package contains a collection of programs that form the base set of the NET-3 networking distribution for the Linux operating system.

It contains the important tools for controlling the network subsystem of the Linux kernel including arp, hostname, ifconfig, netstat, rarp and route.

swordcoast.net IRCd is a fork of Undernets IRCu 2.10.12 that features more possibilities for network services, less power for IRC operators, some of QuakeNets Asuka patches, more versatile host hiding, customizable whois information lines, improvements for silence masks, and a few other things.
Enhancements:
- Apart from integrating all changes made in ircu 2.10.12 and Asuka 1.2.1, this release fixes compile issues, EPITHETs, and issues with privilege propagation.
- It adds a command to adjust MAXOPLEVEL per channel, a user mode to shun people (prevent them from doing anything possibly visible to other users except services), extended host hiding (see README), and forced joins and relaying join to services as requests.

Net::DNS::RR::A is a DNS A resource record. Net::DNS is a DNS resolver implemented in Perl. It allows the
programmer to perform nearly any type of DNS query from a Perl script. For details and examples, please read the Net::DNS manual page.

To read about the latest features, see the Changes file. To find out about known bugs and to see whats planned for future versions, see the TODO file.

Net::DNS does not depend on any C libraries. However, if possible Net::DNS tries to link against a C-library that is supplied with the code. This provides a notable speed increase.

The author invites feedback on Net::DNS. If theres something youd like to have added, please let me know. If you find a bug, please send me the information described in the BUGS section below.

METHODS

address

print "address = ", $rr->address, "n";

Returns the RRs address field.

This is a set of Perl modules that allow you to access the ICQ Instant Messaging. These modules provide you access to creating/receiving messages, writing clients, etc.
After unzipping and untarring the distribution directory,you should be running these commands to install it:
perl Makefile.PL
make
make test
make install
Enhancements:
- Implemented Nezar Nielsens META_USER patch, with some additions.
- Added Net::ICQ object as first param when calling handlers. (IMPORTANT - this will break your existing handlers!)
- Applied Robin Fishers patch for SRV_INFO_FAIL (300) and splitting off the privacy flags from status into a new field privacy. Moved privacy flags into %privacy_codes .
- Added connect(). Now new() does not connect on its own.
- Applied Robin Fishers fix for the weird case where we get V3 packets from
- the server.
- Fixed debug output of packets inside multis, so the events code number is
- printed.

Net::ICQ2000 is a Perl module for handling the ICQ2000 protocol.

This module was written by Robin Fisher and works very well, hes let me take over as the maintainer of the module for the time being and now Im looking to attract more developers to improve this software.

- Clean process flow
- Extensibility
Net::Server is an extensible, generic Perl server engine. Net::Server combines the good properties from Net::Daemon (0.34), NetServer::Generic (1.03), and Net::FTPServer (1.0), and also from various concepts in the Apache Webserver.
Net::Server attempts to be a generic server as in Net::Daemon and NetServer::Generic. It includes with it the ability to run as an inetd process (Net::Server::INET), a single connection server (Net::Server or Net::Server::Single), a forking server (Net::Server::Fork), a preforking server which maintains a constant number of preforked children (Net::Server::PreForkSimple), or as a managed preforking server which maintains the number of children based on server load (Net::Server::PreFork). In all but the inetd type, the server provides the ability to connect to one or to multiple server ports.
Net::Server uses ideologies of Net::FTPServer in order to provide extensibility. The additional server types are made possible via "personalities" or sub classes of the Net::Server. By moving the multiple types of servers out of the main Net::Server class, the Net::Server concept is easily extended to other types (in the near future, we would like to add a "Thread" personality).
Net::Server borrows several concepts from the Apache Webserver. Net::Server uses "hooks" to allow custom servers such as SMTP, HTTP, POP3, etc. to be layered over the base Net::Server class. In addition the Net::Server::PreFork class borrows concepts of min_start_servers, max_servers, and min_waiting servers.
Net::Server::PreFork also uses the concept of an flock serialized accept when accepting on multiple ports (PreFork can choose between flock, IPC::Semaphore, and pipe to control serialization).

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::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."
