i set up an apache httpt server in fedora 9,after it start,i only can acces it in my own pc ,it cannot work in other's ,some can help me out ????

Hi, make sure you have your firewall setup correctly. There is a big possibility that INPUT on port 80 is blocked by default in the Fedora default settings:

You would need to add something like

iptables -A INPUT -s 0.0.0.0/0 -p tcp --dport 80 -m state --state NEW -j ACCEPT

and maybe then you need to run /etc/init.d/iptables save

If this doesnt work make sure your web server is not running on "localhost"

try netstat:

netstat -ntlap|grep -i 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN

and if it works fine should look like that.

Also make sure your ISP isn't blocking port 80 as well, or if you're behind some type of router like a Linksys, you need to forward port 80 to this server for others to access it.
