cannot access apache server from other machines?
 

I have apache running a redhat machine. DHCP is used to get a IP address for the machine.
There's no problem using either "localhost" or dhcp assigned IP address to access some pages on the machine.

But when I tried LYNX dhcp address of the machine from other machines, it failed by showing this:

BEGIN--->
Looking up #.#.#.# first
Looking up #.#.#.#
Making HTTP connection to #.#.#.#
Alert!: Unable to connect to remote host.

lynx: Can't access startfile http://#.#.#.#/
<---END

"#.#.#.#" is dhcp address obtained for the machine.

I tried ssh account@#.#.#.#, it prompts to ask password things. So, I think ssh should work. Also, in httpd.conf, there's a line "Listen *:80".

And there's no problem with browsing internet from mazilla.

What's going wrong? Maybe some low level network settings? To find out the problem, I also tried to allow "ALL:ALL" in hosts.allow and deny nothing in hosts.deny.

Thanks.

Firewall settings maybe? Try running iptables -L and see if there's a firewall rule blocking inbound HTTP traffic.

Thanks a lot! Yeah, its iptables. And I add a rule for passing through port 80 packets. Should read more about those commands for configuring network security:-)
