vplot is a set of Linux routines and programs for plotting on vintage Tek 4010, 4012, 4014, and 4016 storage tube terminals. They can also be used to some extent with xterm's tek emulation. It includes a program that supports a fast parallel interface to the Tek minibus using the Linux parallel port. These are personal routines, not the official Tek Plot10 code.
vpn-shaper is a dynamic traffic shaper for openvpn, poptop, and similar programs, using iproute2. It allows shaping of traffic between many users conected to one server, and it supports different prioritiy schemes for different users and different types of traffic. Trafic shaping uses the HTB qdisc. Prioritization uses l7-filter and ipp2p and some of the patch-o-matic extensions. Classification of trafic in HTB classes is done by using the IPMARC patch-o-matic extension. vpn-shaper requires the IPMARK patch-o-matic extension, connmark iptables match, and HTB qdisc.
vpnd is a daemon which connects two networks on network level either via TCP/IP or a (virtual) leased line attached to a serial interface. All data transfered between the two networks are encrypted using the unpatented free Blowfish encryption algorithm with a key length of up to 576 bits (may be downgraded to a minimum of 0 bits to suit any legal restrictions).
