avahi-publish-service registers a mDNS/DNS-SD service on the local network via the Avahi daemon. It allows services to be discovered by other devices using Avahi or Bonjour-compatible service discovery. This command is equivalent to avahi-publish -s and provides a convenient shortcut specifically for service registration.
The tool requires a service name, a DNS-SD service type (e.g., _http._tcp), and a port number. Optional TXT record strings can provide additional metadata about the service. Service subtypes can be registered for more specific categorization.
The registration persists only while the process is running. When terminated, the service advertisement is automatically withdrawn from the network.

-a, --address=address

Bind to specific address

Register service subtype

Publish in specific domain

Advertise as specific hostname

Enable verbose mode

Don't fail if already published

Common service types:
- _http._tcp - Web services
- _ssh._tcp - SSH servers
- _printer._tcp - Network printers
- _afpovertcp._tcp - AFP file sharing
- _smb._tcp - SMB/CIFS file sharing

Requires avahi-daemon running. Service persists only while command is running. Firewall must allow mDNS (UDP port 5353). Service names must be unique on the network.

avahi-publish-service is part of the Avahi project, created by Lennart Poettering as a free implementation of Apple's Bonjour/Zeroconf protocol, first released around 2005.
