apache2 running but can't visit anywhere

I am try to run two web applications on a Linux Server,one is jsp,another is php.

So I installed tomcat5(use:80) and apache2(:use 8081) on the linux, without doing any things to combine them.
(I just want to them do their own job)

Now,the problem is : tomcat works well,but I can't even vist apache default page by browser,although apache start OK ,no error report,the 8081 port is listening(use netstat -an |grep 8081),the process of httpd is running.

Quote:

tcp 0 0 :::8081 :::* LISTEN 9196/httpd

Can any body tell me the potential reasons?

ps:I install apache on another linux mathine ,same tar.gz ,same change to /apache/conf/httpd.cnf .
And it works well.

I am a Newbie for linux httpd,so ,any advise is helpful .Thanks anyway.

this is my service iptables status

Appears to be a rule to accept traffic on port 80.. so I would think you need a rule to accept traffic on port 8081

ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:80

ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:8081

sorry did u show the commond ?
i tried this

Quote:

[root@localhost ~]# ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:8081
-bash: ACCEPT: command not found

ps:sorry it's 24:00 in china I have to go .Good noon ,everyone.

I'm no expert but I think it would be something like...

iptables -I RH-Firewall-1-INPUT 10 -p TCP -s 0/0 --destination-port 8081 -j ACCEPT

I'm sure someone will correct me if this is wrong... (please do)

thanks very much!! Farslayer ,it works.
