a light-weight HTTP/HTTPS proxy daemon for POSIX operating systems.
Tinyproxy is a small, efficient HTTP/SSL proxy daemon released under the GNU General Public License. Tinyproxy is very useful in a small network setting, where a larger proxy would either be too resource intensive, or a security risk. One of the key features of Tinyproxy is the buffering connection concept. In effect, Tinyproxy will buffer a high speed response from a server, and then relay it to a client at the highest speed the client will accept. This feature greatly reduces the problems with sluggishness on the Internet. If you are sharing an Internet connection with a small network, and you only want to allow HTTP requests to be allowed, then Tinyproxy is a great tool for the network administrator.

Postfix Greylisting Policy Server
Postgrey is a Postfix policy server implementing greylisting developed by David Schweikert.
When a request for delivery of a mail is received by Postfix via SMTP, the triplet CLIENT_IP / SENDER / RECIPIENT is built. If it is the first time that this triplet is seen, or if the triplet was first seen, less than 5 minutes ago, then the mail gets rejected with a temporary error. Hopefully spammers or viruses will not try again later, as it is however required per RFC.

tinc is a Virtual Private Network (VPN) daemon that uses tunnelling and encryption to create a secure private network between hosts on the Internet. tinc is Free Software and licensed under the GNU General Public License version 2 or later. Because the VPN appears to the IP level network code as a normal network device, there is no need to adapt any existing software. This allows VPN sites to share information with each other over the Internet without exposing any information to others.
A ssl/ssh multiplexer.
Applicative Protocol Multiplexer (e.g. share SSH and HTTPS on the same port).
sslh accepts connections on specified ports, and forwards them further based on tests performed on the first data packet sent by the remote client.
Probes for HTTP, TLS/SSL (including SNI and ALPN), SSH, OpenVPN, tinc, XMPP, SOCKS5, are implemented, and any other protocol that can be tested using a regular expression, can be recognised. A typical use case is to allow serving several services on port 443 (e.g. to connect to SSH from inside a corporate firewall, which almost never block port 443) while still serving HTTPS on that port.
