Linux service --status-all shows "Firewall is stopped." what service does firewall refer to?
- by codewaggle
I have a development server with the lamp stack running CentOS:
[Prompt]# cat /etc/redhat-release
CentOS release 5.8 (Final)
[Prompt]# cat /proc/version
Linux version 2.6.18-308.16.1.el5xen ([email protected]) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-52)) #1 SMP Tue Oct 2 22:50:05 EDT 2012
[Prompt]# yum info iptables

When I run:
service --status-all
Part of the output looks like this:
.... Snip....
httpd (pid xxxxx) is running...
Firewall is stopped.
Table: filter

num target prot opt source destination
1 RH-Firewall-1-INPUT all -- 0.0.0.0/0 0.0.0.0/0

iptables has been loaded to the kernel and is active as represented by the rules being displayed.
Checking just the iptables returns the rules just like status all does:
[Prompt]# service iptables status
Table: filter
Chain INPUT (policy DROP)
num target prot opt source destination
1 RH-Firewall-1-INPUT all -- 0.0.0.0/0 0.0.0.0/0
Chain FORWARD (policy DROP)
num target prot opt source destination
1 RH-Firewall-1-INPUT all -- 0.0.0.0/0 0.0.0.0/0
Chain OUTPUT (policy ACCEPT)
num target prot opt source destination
Chain RH-Firewall-1-INPUT (2 references)
.... Snip....
Starting or restarting iptables indicates that the iptables have been loaded to the kernel successfully:
[Prompt]# service iptables restart
Flushing firewall rules: [ OK ]
Setting chains to policy ACCEPT: filter [ OK ]
Unloading iptables modules: [ OK ]
Applying iptables firewall rules: [ OK ]
Loading additional iptables modules: ip_conntrack_netbios_n[ OK ]
[Prompt]# service iptables start
Flushing firewall rules: [ OK ]
Setting chains to policy ACCEPT: filter [ OK ]
Unloading iptables modules: [ OK ]
Applying iptables firewall rules: [ OK ]
Loading additional iptables modules: ip_conntrack_netbios_n[ OK ]
I've googled "Firewall is stopped." and read a number of iptables guides as well as the RHEL documentation, but no luck.
As far as I can tell, there isn't a "Firewall" service, so what is the line "Firewall is stopped." referring to?
