I just wonder how to turn off those 2 services completly since I've got no use for them as they are a security risk in my case. Cause I've got a local device for which I can't Block upnp and that device is using the multicast ip range and the multicast dns can be accessed cause of the problem mentioned above.
Sure I could just block it in the router but I wonder if its possible to just disable it, os wise.
As I googled I found something concerning the stopping of the multicast dns service, instructions were as follows:
# chkconfig --level3 avahi-daemon off
# service avahi-daemon stop
Don't know how to check if its disabled now tho. so I would appreciate it if someone could tell me how to turn off these 2 services?
