Apache stopped working on LAN when on reboot

I set up an Apache server on an old laptop last night (apache2) just to play around on. It worked fine on my laptop, and I could get web pages from it from other computers on my local network. After rebooting the computer, however, the Apache server is not visible on the local network.

nmap TCP connect(), Syn, and ping scans showed that the host was down. An nmap -PN scan, however, showed that the host is up an开发者_如何学God all 1000 scanned ports are filtered.

PHP, MySQL, and PhpMyAdmin are all still working perfectly on localhost, the only problem I can find is that nothing works on local network.

Thanks in advance for the help.

You havent said on your OS, but, there could be a local firewall, or, a change of IP (it could be DHCP) or DNS hasnt caught up properly with DHCP..

a netstat -a should tell you what ports are being listened on. Check its not just listening on 127.0.0.1
