Description
vpnd
vpnd is a handy tool that provides a Virtual Private Network Daemon for encrypted TCP/IP connections. So, if you're looking to secure your network communication, this might be just what you need!
What Does vpnd Do?
vpnd acts like a bridge that connects two networks. It does this through either TCP/IP or a virtual leased line attached to a serial interface. This means your data can travel securely even if the channels aren’t very safe.
How Does Encryption Work?
All the data transferred between these networks is protected using the Blowfish encryption algorithm. This is super cool because it offers up to 576 bits of key length, and you can adjust it down to meet any legal needs.
Not a Replacement
You should know that vpnd isn't meant to replace existing security software like SSH or other tunneling options in your operating system. Instead, it's designed to help secure transparent connections across potentially insecure channels.
Pseudo Terminal Magic
When you set up vpnd, it grabs a pseudo terminal (a pty/tty device pair) and adds a SLIP line discipline to it. This gives vpnd its own network interface called slx—where x is just a number. All IP packets sent here are treated as datastreams by vpnd.
The Encryption Process
This datastream gets encrypted and sent through either a TCP connection or over a serial line to another instance of vpnd on the other end. When it arrives there, it's decrypted and then written back into the pseudo terminal.
Tunneling Network Traffic
The best part? vpnd doesn't mess with the datastream from the pseudo terminal. All packets sent by the kernel through the SLIP interface get transported smoothly. This way, vpnd tunnels network traffic between two systems while being just a user-level daemon.
What's New in This Release:
- Fixed minor bug in generic whitening code
- Fixed PPP MRU setup on Linux
- Ported to x86_64 architecture
- Added 'packetize' option for SLIP/PPP interoperability and RTP header compression (SIP VoIP)
- Added 'smallrtp' option for simple checksum use in RTP packets under 'packetize' mode for reduced bandwidth needs
