You should be running avahi.. it also comes python support.
Here's an example that registers a CNAME that points to your hostname (that
avahi itself publishes)
#! /usr/bin/env python
import avahi, dbus
from encodings.idna import ToASCII
# Got these from /usr/include/avahi-common/defs.h
CLASS_IN = 0x01
TYPE_CNAME = 0x05
TTL = 60
def publish_cname(cname):
bus = dbus.SystemBus()
server = dbus.Interface(bus.get_object(avahi.DBUS_NAME,
avahi.DBUS_PATH_SERVER),
avahi.DBUS_INTERFACE_SERVER)
group = dbus.Interface(bus.get_object(avahi.DBUS_NAME,
server.EntryGroupNew()),
avahi.DBUS_INTERFACE_ENTRY_GROUP)
rdata = createRR(server.GetHostNameFqdn())
cname = encode_dns(cname)
group.AddRecord(avahi.IF_UNSPEC, avahi.PROTO_UNSPEC, dbus.UInt32(0),
cname, CLASS_IN, TYPE_CNAME, TTL, rdata)
group.Commit()
def encode_dns(name):
out = []
for part in name.split('.'):
if len(part) == 0: continue
out.append(ToASCII(part))
return '.'.join(out)
def createRR(name):
out = []
for part in name.split('.'):
if len(part) == 0: continue
out.append(chr(len(part)))
out.append(ToASCII(part))
out.append('\0')
return ''.join(out)
if __name__ == '__main__':
import time, sys, locale
for each in sys.argv[1:]:
name = unicode(each, locale.getpreferredencoding())
publish_cname(name)
try:
while 1: time.sleep(60)
except KeyboardInterrupt:
print "Exiting"
