pybonjour 1.1.0

pybonjour provides a pure Python interface (via ctypes) to Apple Bonjour and compatible DNS-SD libraries (such as Avahi). The application allows Python scripts to take advantage of Zero Configuration Networking (Zeroconf) to register, discover, and resolve services on both local and wide-area networks. Since pybonjour is implemented in pure Python, scripts that use it can easily be ported to Mac OS X, Windows, Linux, and other systems that run Bonjour. Examples The following scripts are included in the examples directory of the pybonjour source distribution. Registering a Service register.py Script import select import sys import pybonjour name = sys.argv[1] regtype = sys.argv[2] port = int(sys.argv[3]) def register_callback(sdRef, flags, errorCode, name, regtype, domain): if errorCode == pybonjour.kDNSServiceErr_NoError: print Registered service: print name =, name print regtype =, regtype print domain =, domain sdRef = pybonjour.DNSServiceRegister(name = name, regtype = regtype, port = port, callBack = register_callback) try: try: while True: ready = select.select([sdRef], [], []) if sdRef in ready[0]: pybonjour.DNSServiceProcessResult(sdRef) except KeyboardInterrupt: pass finally: sdRef.close() Example Output $ python register.py TestService _test._tcp 1234 Registered service: name = TestService regtype = _test._tcp. domain = local. Browsing for and Resolving Services browse_and_resolve.py Script import select import sys import pybonjour regtype = sys.argv[1] timeout = 5 resolved = [] def resolve_callback(sdRef, flags, interfaceIndex, errorCode, fullname, hosttarget, port, txtRecord): if errorCode == pybonjour.kDNSServiceErr_NoError: print Resolved service: print fullname =, fullname print hosttarget =, hosttarget print port =, port resolved.append(True) def browse_callback(sdRef, flags, interfaceIndex, errorCode, serviceName, regtype, replyDomain): if errorCode != pybonjour.kDNSServiceErr_NoError: return if not (flags & pybonjour.kDNSServiceFlagsAdd): print Service removed return print Service added; resolving resolve_sdRef = pybonjour.DNSServiceResolve(0, interfaceIndex, serviceName, regtype, replyDomain, resolve_callback) try: while not resolved: ready = select.select([resolve_sdRef], [], [], timeout) if resolve_sdRef not in ready[0]: print Resolve timed out break pybonjour.DNSServiceProcessResult(resolve_sdRef) else: resolved.pop() finally: resolve_sdRef.close() browse_sdRef = pybonjour.DNSServiceBrowse(regtype = regtype, callBack = browse_callback) try: try: while True: ready = select.select([browse_sdRef], [], []) if browse_sdRef in ready[0]: pybonjour.DNSServiceProcessResult(browse_sdRef) except KeyboardInterrupt: pass finally: browse_sdRef.close() Example Output $ python browse_and_resolve.py _test._tcp Service added; resolving Resolved service: fullname = TestService._test._tcp.local. hosttarget = bumble.local. port = 1234 ....
