Thank you for this very informative post. This is what I was looking for. If I read this right, my router will automatically block incoming connections unless I have set up port forwarding to allow it. Further, unless I am running the service that the connection is looking for, the connection would be refused anyway.
I have been to shields up and this system passes all of their tests there, other than the IP of my router being visible. This is the message that I get, "Your system has achieved a perfect "TruStealth" rating. Not a single packet, solicited or otherwise, was received from your system as a result of our security probing tests." I guess that should provide me some peace of mind.
Is there any way for there to be intrusion on port 80, since that will be used for normal internet traffic?

getdomainname
getdomainname(2) System Calls Manual getdomainname(2)
NAME
getdomainname, setdomainname - get or set name of current Network Information Service domain
SYNOPSIS
DESCRIPTION
returns the name of the Network Information Service (NIS) domain for the current processor, as previously set by The parameter namelen
specifies the size of the name array. The returned value is null-terminated unless the area pointed to by name is not large enough to hold
the domain name plus the null byte. In this case, only the namelen number of bytes is returned.
sets the domain of the host machine to name, which has a length of namelen. This call is restricted to the superuser and is normally used
only when the system is booted.
These Network Information Service domains enable two distinct networks with common host names to merge. Each network is distinguished by
having a different domain name. Currently, only the Network Information Service uses these domains.
RETURN VALUE
If the call succeeds, a value of 0 is returned. If the call fails, a value of -1 is returned and is set to indicate the error.
ERRORS
If or fail, is set to one of the following values:
name points outside the accessible address space.
The caller is not superuser.
This error only applies to
WARNINGS
The length of the name array should be at least 65; NIS domain names can be up to 64 characters long.
NIS servers use the NIS domain name as the name of a subdirectory of Since the NIS domain name can be as long as 64 characters, the domain
name set with can exceed the maximum file name length allowed on the local file system. If that length is exceeded, the name of the subdi-
rectory is the truncated NIS domain name.
