Do you have iptables (or some other firewall) running on the linux system? If so, is port 8080 open? Does the Linus system have a monitor, and if so, can you access JBoss from there using http://localhost:8080?

hi,guy,
thank you for replying,I'm not sure whether some firewall running on my linux.But I use nmap ,netstat,find the port 8080 is open.So what's wrong with my linux.Btw,my linux is running on the command line,so I don't know how to access "http://localhost:8080" on the command line.

nmap -A -sT localhost

You can have port 8080 open and still have the firewall block access to the the port from extrnal machines. You really neeed to find out if a firewall is running. I don't use Gentoo (I run Fedore Core 5), so I am not sure the best way to find that out.

Also, there are command-line HTTP clients that you can use to browse web sites. You only get text back, but it would be enough to show that JBoss is processing http requests. Perhaps you could try one of those. (I don't recall the name(s) of the http client, that was one of the installation options I turned off when I installed Fedora.)

hi,peterJ
I run Fedore Core 5 too.I find firewall,it's iptables,now,what can I do?Turn firewall off?
chkconfig --list|grep iptables
iptables 0:off 1:off 2:on 3:on 4:on 5:on 6:off

[brooksj]

ok,I can use command-line http client(Wget) access "http://localhost:8080".So,how to find port that firewall block and open it.

Here are the JBoss-related lines I added to /etc/sysconfig/iptables:

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 1099 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 1098 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 4444 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 4445 -j ACCEPT

The above lines must go before these lines:

-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited
COMMIT
