Hyenae is a highly flexible and platform independent network packet generator. It allows you to reproduce low level Ethernet attack scenarios (such as MITM, DoS, and DDoS) to reveal potential security vulnerabilities of your network. Besides smart wildcard-based address randomization, a highly customizable packet generation control, and an interactive attack assistant, Hyenae comes with a clusterable remote daemon for setting up distributed attack networks.
Webtunnel is a network utility that encapsulates arbitrary data in HTTP and transmits it through a Web server. In that regard, it is similar to httptunnel. However, its server component runs in the context of a Web server as a CGI application (with optional FastCGI support), so it does not need its own port. It supports most things that the Web server supports, such as authentication, HTTP 1.1, HTTPS, and client certificates. It uses simple requests and responses so it works seamlessly through forward and reverse proxies.
SmbSync is a program to move files between Unix and Windows shares directly, avoiding the need for mounts or extra services like FTP or Rsync. It uses input and output directories, and can be configured to handle many directories and servers. It can retry uploads and downloads that fail, avoids incomplete file transfers, does not touch recently modified files with a configurable timeout, can archive files instead of deleting files transferred, can upload or download to temporary directories so that scripts that trigger on the files will only see complete files, and allows you to configure blocksize.
Nall is a small status icon application that discreetly fits into the system tray. Its purpose is to spawn a list of user scripts periodically and display one line of output per script in a tooltip window. Thus, it is possible to "monitor" any kind of event that can be detected with a script. Nall does not care about the return values of the scripts it runs, but only displays their output. It is also easy to interface nall with Nagios plugins.
Nightwing allows the creation of quickly deployed wireless networks without the need to make complicated configurations. With the implementation of a Mesh technology called B.A.T.M.A.N, Nightwing allows the extension of wireless networks with a simple way of adding devices that works with minimal human intervention. It has public and private connection interfaces, and the ability to filter content using OpenDNS. It is designed with security in mind, and has low hardware requirements.
WANsim allows you to simulate (more accurately, emulate) a WAN connection. In particular, it allows a user to change the emulated WAN speed, latency, variation, packet loss, packet duplication, and packet corruption aspects. It is configured as a network bridge that is established at boot time and uses the Linux Kernel NETEM functionality to accomplish its goals. Although relatively well documented, this functionality is not the easiest to use. WANsim wraps it into a simple to use script.
