Serial TUN/TAP Encapsulation (Stuntapen) is a simple program that implements a SLIP (RFC 1055)-like algorithm, extended to allow either IPv6 packets (when using a TUN device) or Ethernet frames (when using TAP) to be transferred over some kind of a serial line, such as a computer's serial port, a TCP stream, or an SSH session. When used together with Netcat or SSH, it could be used to create a crude but working IP tunnel or VPN, or to forward IP traffic to a low-feature embedded system via a serial line or USB, or for educational purposes.
MuLaNEO implements algorithms to design and provision resilient multi-layer networks, or hierarchies of technologies (IP/MPLS, Carrier Ethernet, SDH/SONET, etc.). It includes modelling of these technologies, visualizes their interrelations, and allows the dynamic provisioning of the resulting networks on the basis of path computation elements (PCE).
log2command was created as a sort of reverse fail2ban or cheap VPN-firewall: a machine with a closed firewall can be told, by a foreign machine, to accept connections from a specific IP. log2command then keeps track of the Web server log file and watches for inactivity from the user's IP. After an amount of time, another command is executed that can remove the user's IP from the firewall, closing down the machine again. The PHP script is a command line program that can be run in the background.
libsockmux-glib is an implementation of the sockmux protocol, using GIO data types and using glib functions internally. The interface offered to applications is very simple and straightforward. sockmux specifies a simple way for muxing messages and data streams onto a single socket for network and local communication streams.
