Ok folks, I am using FreeBSD 6.2 and apache22. I am getting a response of 'Permission Denied' make_sock: could not Bind 0.0.0.0:80. Orignally I receive a response of 'Could not reliably determine the server's fully qualified domain name', using alclasystems.com as the server name.
Now Binding to, I assume, port 80 is the problem. Yes, I am at the root under 'su'. I believe I was not at the root for the latter portion of this message for DN orginally. I have nothing using this port that I may be aware of. This OS(FBSD) and apache22 is running without any other activity. What am I missing here?

the clue is here:

Bind 0.0.0.0:80

who's IP adress is that ?!?!?

Who's address indeed! That is the broadcast address. It is not assigned to any specific computer.

Edit: just in case anyone reads this later, the x.x.x.0 is the network number and x.x.x.255 is the broadcast address. Ooops.

What do you mean?
Are you saying this is someone's IP address? If so, Am I suppose to apply an IP address? If so, How?
I thought when logging in through FBSD and 'su', starting the apache22 applic, via command: apachectl start, this would automatically connect me. Am I suppose to map an address. If so, how? I do have a registered DN and I am connected through a router with the address 192.168.1.1

we are saying this address is NOT valid.

well, ok, good, using apachectl is correct.
usually it will start it up on the localhost, it would seem the
config is wrong. maybe it's a freebsd thing.

it seems odd.

so you are doing
/usr/sbin/apachectl start ?

are you sure it's not up already?
tried localhost in a host browser

Not sure. I'll check (/usr/sbin/
Thanks

Why would it not be valid? 0.0.0.0 would mean the server is listening on all available interfaces.

It's trivial enough to check whether something is already listening on tcp port 80.

sockstat -4

The following paper will help give you the background to answer this question:

*SIGH*

From `netstat -tunap`:

Do you understand what I've meant by it being valid now?

well there you go
i stand corrected

I suspect that netstat is merely displaying the 32-bit value configured with no bounds-checking. In many ways, I would not want netstat to be checking every value it receives as this would be additional administrative overhead.

If you read the paper previously linked, you will find classful & classless (CIDR) addressing discussed. In either model, the all-ones address & all-zeroes address have special meanings. You will also find that the 32-bit IPV4 addressing scheme used today is based on inefficient assumptions, & has been overly patched to meet today's need of addressing millions of hosts as opposed to 2^32.

I am somewhat familiar with the limited ability usage of IPV4. But this problem(Permission denied) is persistent.
