Cannot access certain pages served by Apache

[Guest xfmandrake]

Architecture 1 : X86

Mandriva Linux Version Limited edition 2005

Subcategory Web Server (Apache) **

Question text This is really strange and has puzzled me for months.

 

Real Gurus, I need your help here.

 

I am running an apache server 2.0.54 on a Mandrake Linux (limited edition

2005), using DSL (PPPoE) and a Netgear router. Very standard configuration:

DSLModem->Router->machines in LAN. I had many experiences in those things and

confirmed the following using various tools/tests:

 

1. Port 80 is not blocked;

2. Port 80 is open/forwarded in router.

3. I can access some HTML pages from outside of LAN.

4. Apache listening at 80 and port=80.

 

Strange thing is,

 

I can not view certain pages, like my phpBB2 forum and image files, even some

HTML files.

 

I checked all conf files and .htaccess files(if any), none is restricting my

access to those files/file types. However, I can view those pages from LAN

machines w/o any problems. That\'s true even I use WAN ip in the address bar

in IE from LAN PCs. I just can not view those files from outside for no

reasons. Even stranger, the access_log show status code 200 and no errors

logged in error_log. The inaccessible pages from outside are just hanging

there for some time and then I saw \"Can not find the server\" and \"The page

cannot be displayed\".

 

I even shutdown firewalls with the installation(iptables/shorewall, etc.), but

problem persists.

 

The linux was installed on an IBM machine dual-booted with Windows NT 4.0, if

that helps.

The Linux part was partitioned using ext3 file system as prompted.

 

As a starting point, can you guys access the following page:

 

http://68.158.112.148/test.gif

 

I confirmed that this is an Apache configuration issue instaed of network

issue. I installed PWS in another win98 machine and I can access any page on

that server w/o any problem. When I installed Apche on that Win98 machine, I

saw the same issue.

 

Anyone knows what could be wrong with my Apache?

Any advices/suggestions were greatly appreciated.

 

Thank you in advance, Gurus.

Welcome to the board

 

Please don't double-post. I've therefore removed your previous post from software. :P

Have you checked with your ISP to ensure that they allow you to run a web server? Some ISP's are in the habit of blocking it.

Thanks for the reply.

 

I made sure my ISP did not block port 80 and no place in my conf or .htaccess to restrict access to any files.

I can actually access some html pages like this:

 

http://68.158.112.148/test.html

 

But for some reason I can not access this page:

 

http://68.158.112.148/pws_install.html

 

Sounds really strange.

 

When I use telnet 68.158.112.148 80 from remote outside of lan. I can get /pws_install.html though.

 

I can access any pages including all images in the lan.

 

Any advices will be appreciated.

Another proof that my ISP does not block port 80 is, I installed Apache on another machine and if I port-forwarded 80 to that machine(win98), I can access all files there.

 

What I suspect is,

1. Will dual boot of Linux and WinNT4.0 cause the problem? But my partition for linux is EXT3 as prompted.

2. I check iptables and shorewall firewall and showewall allows port 80 from net to fw. Are they 2 independent firewalls? Both were running in the standard installation. I assume shorewall is just a configuration tool for iptables to work so I only checked shorewall config files.

 

Thanks.

I found out the root of the problem : my Apache server can not send files more than 1500 bytes (regardless of file types)!

 

My router also set mtu size 1500. But it should break files into pieces should it be larger than that? What's your router's MTU seeting, does this matter?

 

Anyone knows what's wrong here?

 

Thanks!

directory indexing ?

i.e.

index.htm

index.php

index.html

will not show pages named Default.htm or pages named Default.html

check your subdirectories for the same

 

running virtual domains ?

 

sounds like traffic from the router is getting bounced .

 

Why are you here?

Trying 68.158.112.148...

Thanks for the reply.

 

The index pages are fine. You can access index.html on this server. Just if file size>1500bytes, IE hangs.

 

BTW, you'd put a new line after prompt at telnet, then type in

 

GET /pws_install.html HTTP 1.0

 

You'll get the page via telnet. But in my case I can not access from IE. Really odd.

 

The files a little bit larger than 1500bytes moight be fine some time. But 10MB is definetely failing at browser.

 

I just created a separate topic and let's talk about there.

 

Thanks!
