Virtual ISP / IP tunnel daemon for cjdns.

Elvisp (Work in Progress)

El (Spanish for the) VISP (Virtual Internet Service Provider)

Elvisp assigns IPv6 and/or IPv4 addresses for a cjdns-based IP tunnel using the public key for the connecting node. It will add the user's assigned address with cjdns' admin API. Elvisp then returns the assigned address(es).

Installation

go get github.com/willeponken/elvisp/cmd/...

Usage

Elvispd flags

Usage of elvispd:
  -cidr value
    	CIDR to use for IP leasing, use flag repeatedly for multiple CIDR's.
  -cjdns-ip string
    	IP address for cjdns admin. (default "127.0.0.1")
  -cjdns-password string
    	Password for cjdns admin.
  -cjdns-port int
    	Port for cjdns admin. (default 11234)
  -db string
    	Directory to use for the database. (default "/tmp/elvisp-db")
  -listen string
    	Listen address for TCP. (default ":4132")
  -password string
    	Password for administrating Elvisp.

Example:

elvispd -cidr 192.168.1.0/24 -cidr 1234::0/16 -cidr 172.16.0.0/12 -cjdns-password 6c12zbnNoThisIsntMyRealPasswordn7x1

Which will add the users / nodes to subnets:

• 192.168.1.0/24
• 1234::0/16
• 172.16.0.0/12

So the first user will get:

• 192.168.1.1
• 1234::1
• 172.16.0.1

Elvispc flags

Usage of elvispc:
  -a string
    	Address for server.
  -l	Request lease.
  -r	Remove client.

Example:

elvispc -a 127.0.0.1:4132 -l # Request lease
elvispc -a 127.0.0.1:4132 -r # Remove client

elvisp's Issues

Elvisp client

Unit testing

IPv4 and IPv6 support

As of now, there's only IPv6 support. There should be support for both protocols at the same time.

Documentation

Support for multiple IPv6 and IPv4

Current implementation supports only one IPv4 CIDR and one IPv6 CIDR.

All CIDR's could be inside a slice.
