sedire is a multicast reflector and proxy. It is most commonly used with service discovery protocols, including DNS-SD/mDNS and DIAL/SSDP, to enable clients and servers to exist on different (V)LANs or even in different locations. sedire makes it possible to keep devices and users isolated and appropriately firewalled even when dynamic service discovery protocols are needed between the networks.
sedire is still under active development, but the current version of code-complete and fully-functional. Users are free to build sedire as-is and test it out in their environment. The remaining key items blocking the formal initial release are:
- Full set of documentation (including manpage)
- Init scripts (i.e.
systemdunit file)
The goal for the launch of the initial version of sedire is by the end of 2022Q3.
Contributions of code and documentation are welcome, as are bug reports and suggestions! Please see the project's CONTRIBUTING page for more information.
Until full documentation is available, the basic operation of sedire can be tested as follows:
go build github.com/packetspace/sedire
./sedire -MS -i eth0 -i eth1 -l info < /dev/null > /dev/null 2>&1 &
disown
This will launch an instance of sedire as a daemon with normal logging to the local syslog. It will be configured for handling standard mDNS and SSDP protocols, which should enable support for DNS-SD and DIAL in most environments.
