Enable Linux firewall to support connection tracking and NAT of H.323 protocol. It supports RAS, Fast Start, H.245 Tunnelling, Call Forwarding, Signal Proxy/Softswitch, RTP/RTCP and T.120 based audio, video, fax, chat, whiteboard, file transfer, etc.
ip-session gets info of network trafic, such as sip, dip, sport, dport, etc. from linux kernel; gets account info of each traffic, such as in/out bytes/pkgs, etc.; else, gives session management function, such as query/del, etc.
A Firewallscript for Linux which allows you to do easy loadbalancing, dualrouting, failover, traffic control, etc. The script allows you to set up things in a few settings files and just run (after some kernel patching ;) ).
Linsec is a shell script firstly designed for slackware linux 10 and now supports most of linux distros. Linsec improves security of Linux systems (kernel parameters, network behaviour, iptables, critical files permissions)
New customers can spin up VMs, build with AI, and query data at no cost.
Put your $300 in credit toward real workloads, then keep building with free monthly usage for 20+ products. No commitment and no charge until you upgrade.
The Knock Project is a collection of security tools providing increased client/server authentication. The server and its functionality is provided by the netfilter kernel interface. Included are the daemon, a GNU/Linux client and a Windows client.
IP Traffic Volume: Logs (counts) in- & outgoing bytes through network device(s) using kernel iptables. Highly configurable as to which bytes are logged, e.g. to/from specific ports or ip-addresses. Data displayed in html via cgi or plain ascii to console
Networkdesigner is a tiny gui to create a visual network-topology, to define services an release them to any networkdevice. After that a firewall script on base of ip-tales base linux kernel can be created.
We have just released a new set of files.
This project will consist of a module for Firewall Builder. This module will be an add-on to Firewall Builder that will allow a user to create, compile, and apply firewall rules to a machine with Netnice Packe

Bash script that uses iproute2 and shapecfg (shaper.o) to limit incoming and outgoing traffic on a linux router. Also haves option for supporting more than 100 shapers via kernel patch.
A replacement firmware distribution for the 3com 3CRADSL72 a.k.a 3com wireless 11g (distributed by Ya.com) and its identical twin, the SMC7804WBRA, with an ucLinux kernel based system and associated system tools.
Development area for GNU/Linux 2.6.x for the KS8695 ARM SoC. Covers kernel patches, drivers for serial, Ethernet, PCI, GPIO, watchdog subsystems, and drivers for optional PCI based devices such as USB, WiFi, WiMAX, IPSec, SSL, and RSA devices.
SynAckFlood protect your linux box from portscan attacks, make a ficticious responce parallel to kernel, and portscanner show you that all ports are openned
CBQ.init script demonstrate power of CBQ mechanism in network traffic management under Linux platform. This bash script parses human-readable config files and does all needed manipulation with 'tc' linux kernel utilite. See WebCBQ project for Web GUI.
The aimed users of this project are ISP, that uses Linux and Linux-based hosts as routers/servers. Requirements : Perl interpreter, iproute2 and iptables or ipchains. These perl scripts, will configure Linux kernel, routing, packet filter and QoS.
A Webmin module for maintaining the FreeBSD Firewall.
This module allows the user to configure the FreeBSD firewall via webmin.
Operating systems supported: Freebsd 4.7 and 5.x
This module runs under webmin > 1.070
A very simple Linux firewall scripts designed for home users/small office users. Requires Linux kernel 2.4.x, ipcalc and iptables to run. These scripts have been tested on Trustix 1.2, 1.5 and 2.0 (Beta), Redhat 7.2, and 7.3 only.
...The primary design goals are security, ease of use, and performance, in that order. It takes advantage of advanced features of iptables, tcpwrappers, and the Linux kernel.
Loggrep greps kernel logfiles on ipchains and iptables firewall log entries and features the ability to filter against given entries (date, IP, port, ..).
It also features quasi-detection of protscanning, line count
and html output.
IPFC is a distributed management solution for security module (firewall, nids). Security module can be packet-filtering (ipfw,netfilter,ipf ...), NIDS or any other servers (syslog...) or embedded devices.
1.68MB floppy using the 2.4.6 kernel which includes IPTABLES. Most if not all packages in this dist are out of date. I would recommend using LEAF at http://leaf-project.org/ which is more up to date.
