The connection was refused when attempting to contact the localhost

I cannot connect to my localhost.
I tried localhost, localhost:80 and localhost:8080.
My httpd.conf file is listen 192.1768.1.100:8080 which is the location
of my linux server on a lan with two computers connected by a
linksys 4 port befsr41 router v3

My localhost was working yesterday.
I followed instructions to install mysql, php and apache from
http://www.nitecon.com/downloads/rh9tut.htm

Could a change in IP address cause the problem?
My hosts in etc/ folder has the following entry.

127.0.0.1 localhost.localdomain localhost

These commands were done from my web server which never worked.

It is, really? Is your configuration file typing on a par with your Usenet
typing?

ALWAYS COPY the EXACT contents of your configuration files to your post.

NEVER try to SUMMARIZE the contents by typing them in from memory.

Taken at face value, your entry:

> My httpd.conf file is listen 192.1768.1.100:8080

IS THE PROBLEM.

Curious why you expect a server listening ONLY on 192.168.1.100:8080 to
answer a query to localhost (127.0.0.1) or port 80? Perhaps you should
change that to Listen 8080, so it will listen to that port for any IP on
your box (including localhost).

Thank you David and Paul for your expertise on this problem.

Here is a copy of my edited httpd.conf file. I s
#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, in addition to the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses (0.0.0.0)
#
#Listen 12.34.56.78:80
Listen 8080

#
# Load config files from the config directory "/etc/httpd/conf.d".
#
Include conf.d/*.conf
I could not access my localhost with listen 8080 but when I changed it
to 80 I could access it.
People outside my lan cannot access my ip address with my apache
started.
Not sure if I changed my http.conf to listen 8080 if this would help?
Seems to be related to my linksys router I guess. Here are the specs.

Routing Table Entry
Dest Lan IP Subnet Mask def Gateway Hopcount Internet
0.0.0.0 0.0.0.0 66.130.104.1 1 Internet
66.130.104.0 255.255.255.0 0.0.0.0 1 Internet
192.168.1.0 255.255.255.0 0.0.0.0 1 Local
local dhcp server enabled
DDNS disabled
UPnP enabled
PPPoE Passthrough Disabled
IPSec Passthrough Disabled
DMZ Disabled
Admin Port 8081

If you find anything wrong with this setup that would interfere with
putting my live please let me know.
Thanks,
Rob

I assume you forwarded port 8080 on the Linksys to Linux IP.
Does 'netstat -atn' on Linux show anything listening on 0.0.0.0:8080?
Do apache logs give any clue of attempting connection when it is set to
Listen 8080 and someone attempts to connect to your URL with that port?

Thanks for your help Dave. When I tried netstat -atn it didn't seem to
be listening to any particular site like some other ports seemed to be
listening. I tried to reboot my computer without the router and it
said as I logged in

"Could not look up internet for x1-6...-84
This will prevent GNOME from operating correctly.It may be possible to
correct this problem by adding x1-6...-84 to the file /etc/hosts."

I selected Login anyway and my Apache wouldn't start. I added the
value to the hosts file and Apache worked. I reconnected the computer
to the router and it worked as well. I still have no idea why this
worked.
Next step is to see how much security I have on my server.
Thanks again,
Rob
