spotty access to web server

[McDougall, Marshall (FSH)]

Is the problem maybe upstream?  Is the firewall (which you don't
control, and I do feel your pain) getting overwhelmed and your
outsourcer is not willing to do anything about it cause it's not in the
contract?  If you are not showing anything in the access or error logs,
then I would suggest that they are plain not getting to your box. 

The body that controls your firewall needs to participate in your
troubleshooting process.

P.S. I can get to your site with no problems.

Subject: spotty access to web server


I am having a problem with my web server that is difficult for me to 
resolve. I have a web server at

http://aa.usno.navy.mil/

that most people can get to just fine. However, there are a small number

of people that get a "connection refused" error. I have had a difficult 
time finding someone who:

1) gets this error
2) is technically savvy
3) willing to help

I have finally found someone, but I still can't solve this problem.

My server is behind a firewall (which I don't control). This helpful 
soul can get to other web servers behind the firewall, but not to this 
one. He did a traceroute, which was successful. I asked him to do a

telnet aa.usno.navy.mil 80

He got a "connection lost to host" error.

I was successful in doing a lookup and a reverse lookup on his IP 
number, so I don't think the server is having problems with DNS. His IP 
number and name do *not* show up in either web server logs or in system 
logs. It is as though he never tried to access the machine at all. I do 
have iptables on the machine, but I turned it off to see if it was the 
culprit. He still has the connection problem, so I guess iptables isn't 
the problem.

Does anyone know what I might try to solve this problem?
