Just to verify that, I changed the Listen directive in my httpd.conf file from 80 to 81 and Apache starts OK. So, let me see what is using port 80: > > # netstat -plant | grep 80 > tcp 0 0 127.0.0.1:8000 0.0.0.0:* LISTEN 3091/nasd > tcp 0 0 192.168.1.100:51869 75.180.132.46:443 ESTABLISHED 3803/epiphany > tcp 0 0 192.168.1.100:58782 64.154.83.64:443 ESTABLISHED 3803/epiphany > tcp 0 0 192.168.1.100:54960 64.154.83.64:443 ESTABLISHED 3803/epiphany > > Nothing!! OK, now I'm confused. How do I get netstat to show me who is using port 80? Port 80 doesn't show up in the netstat output because it is not being used any more! httpd itself was trying to use port 80 twice. I had tried to use system-config-httpd to change some settings and this created a system-config-httpd.conf file in /etc/httpd/conf.d. All the files in the conf.d directory are included by httpd.conf and so there were 2 'Listen 80' directives. This would seem to be a bug to me but it is on an FC6 system running: # rpm -qa | grep httpd httpd-2.2.6-1.fc6 system-config-httpd-1.4.1-1.fc6 so perhaps it is fixed now. On to my next problem. Why can't this FC6 box see any http traffic from a Windows Vista box on my local network when it is obviously connecting to various web sites? I'm using Wireshark and yes, I have opened up the firewall. I can see ICMP traffic and other protocols from the Windows box and I can see http traffic from my FC6 box. Steve.
