[gentoo-user] Issues pinging localhost and starting apache.

[Jordan Woehr]

*I first encounter this problem while trying to setup Apache for my 
machine. I only want it to run locally on my network. First issue, I try 
to start Apache and have it listen to port 80 but it won't start with 
the error:*

apache2ctl start
 * Caching service dependencies 
...                                       [ ok ]
 * Starting apache2 ...
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

*The only lines I have added to httpd.conf are as follows:
*
ServerName localhost
Listen 80

*Having Apache listen on port 8080 instead results in it starting fine. 
Thing is, I'm pretty sure nothing is listening on port 80.*

netstat -an | grep :80
tcp        0      0 192.168.0.104:56125     66.150.96.119:80

TIME_WAIT

TIME_WAIT

ESTABLISHED

*I was not happy with Apache not starting listening to port 80 but I 
started it on 8080 instead. Tried  going to  localhost:8080 in firefox 
but received an unable to establish connection error.

 From there I went to my hosts file which is as follows

*127.0.0.1       localhost

*Tried scanning 127.0.0.1 with nmap:

*nmap -sT -PT 127.0.0.1

Starting Nmap 4.20 ( http://insecure.org ) at 2007-11-22 17:11 MST
Note: Host seems down. If it is really up, but blocking our ping probes, 
try -P0
Nmap finished: 1 IP address (0 hosts up) scanned in 3.342 seconds

*And now a ping
*
ping -c 5 localhost
PING localhost (127.0.0.1) 56(84) bytes of data.
 From 10.132.0.1 icmp_seq=1 Destination Net Unreachable
 From 10.132.0.1 icmp_seq=3 Destination Net Unreachable

 From 10.132.0.1 icmp_seq=5 Destination Net Unreachable

--- localhost ping statistics ---
5 packets transmitted, 0 received, +4 errors, 100% packet loss, time 4000ms

*localhost seems to be resolved properly to 127.0.0.1 but what I don't 
understand is where the 10.132.0.1 comes from. This computer's ip on the 
network is 192.168.0.104 (static) and my ip on the internet is 
77.something.something.something (was when I did the ping at least).

I hope the above is enough information. Suggestions on why Apache won't 
start listening on port 80 and why I can't connect to localhost:8080 
from firefox when Apache is running are welcome.

Thanks
Jordan
