Strange port 80 access problem

I have a very strange access problem that just popped up this morning. For
whatever reason, my machine at home over my cable modem can no longer access
Apache on port 80... However other services are accessible elsewhere (Direct
Admin control panel, FTP, SMTP,etc...) BUT Apache is accessible to other
devices, not on my IP... It seems as though there is some sort of IP block
on me, but I can't seem to find anything in the logs to confirm this. I
don't have a 'deny from' in any .htaccess files... What could be going on?

I'm running apache 1.3.39, and FreeBSD 6.1.

Re: Strange port 80 access problem [In reply to]

Can you clarify? Apache is running at home? Your trouble accessing it is
from home? From a different machine? The "other devices" are at home, or
external? If your Apache is served from home via your cable modem, has
anyone tried to test it from outside? Have you tried running Apache on a
different port than 80 to see if your cable co is blocking port 80?

You mean that from outside your 4 walls port 80 does not answer?
Can you access Apache locally, with http://127.0.0.1 ?
If not, then Apache is not listening on port 80 or is down .
Another possibility is that, for some reason, you got on a black list
and your ISP is blocking calls to you...

RE: Strange port 80 access problem [In reply to]

Sorry all... I guess I wasn't clear enough...

My server is in a colo facility, publicly accessible to the world. It
appears as though just I could not access it from my home IP, but I could
from my phone, outside my home, etc...

The problem has 'fixed' itself, I haven't done anything to the server or my
local machine. It looks like it may have been a block put on by my ISP...
Maybe because I have a monitoring tool running hitting my site every 2
minutes.

It was very strange.

LOL@ every 2 minutes.

That'll do it. ISP's are quite picky about targeted traffic sometimes,
especially
if your ISP's tech guy is a control freak.

Re: Strange port 80 access problem [In reply to]

Do you have more than on machines in your network that have port 80 open ?
Any of those are Windows boxes ?
If yes only keep the main server running and try again. Also, check the
router if any, on the forward configuration.

Hope this helps to see the light...
