OOPS Firewall 의 실행 파일은 rpm이나 deb로 설치를 했을 경우 /usr/sbin/oops-firewall이
다. 소스 설치를 했을 경우에는 prefix/bin/oops-firewall 또는 --bindir 값으로 준 디렉토
리의 @bindir@/oops-firewall에 위치한다.

$ /usr/sbin/oops-firewall 

로 실행을 하든지 RPM,deb 로 설치를 했을 경우에는

$ /etc/rc.d/init.d/oops-firewall start

로 할수가 있다. init file 은 start, stop, restart, status 의 flag 들을 가지고 있다.

 [root@bbuwoo oops-firewall]$ /usr/sbin/oops-firewall -v
 [root@bbuwoo oops-firewall]$ /etc/init.d/oops-firewall start
 [root@bbuwoo oops-firewall]$ /sbin/service oops-firewall start

 다음은 oops-firewall 을 구동하는 명령을 보여준다.  oops-firewall 은 구동시
 에 기존의 룰을 모두 초기화 한후에 다시 룰을 설정하도록 되어 있다.

 [root@bbuwoo oops-firewall]$ /etc/init.d/oops-firewall stop && \
                              /etc/init.d/oops-firewall start
 [root@bbuwoo oops-firewall]$ /etc/init.d/oops-firewall restart

 아래의 경우에는 필자의 서버에서 oops-firewall명령어를 직접 실행 시켰을
 경우이다.

 [root@bbuwoo oops-firewall]$ /etc/rc.d/init.d/oops-firewall stop
  Destory Firewall Tables:                                   [  OK  ]

 또는 직접 iptable 를 이용하여

 [root@bbuwoo oops-firewall]$ /sbin/iptables -Z
 [root@bbuwoo oops-firewall]$ /sbin/iptables -P INPUT ACCEPT
 [root@bbuwoo oops-firewall]$ /sbin/iptables -F INPUT
 [root@bbuwoo oops-firewall]$ /sbin/iptables -P PORWARD ACCEPT
 [root@bbuwoo oops-firewall]$ /sbin/iptables -F PORWARD
 [root@bbuwoo oops-firewall]$ /sbin/iptables -P OUTPUT ACCEPT
 [root@bbuwoo oops-firewall]$ /sbin/iptables -F OUTPUT
 [root@bbuwoo oops-firewall]$ /sbin/iptables -t nat -Z
 [root@bbuwoo oops-firewall]$ /sbin/iptables -t nat -P PREROUTING ACCEPT
 [root@bbuwoo oops-firewall]$ /sbin/iptables -t nat -F PREROUTING
 [root@bbuwoo oops-firewall]$ /sbin/iptables -t nat -P POSTROUTING ACCEPT
 [root@bbuwoo oops-firewall]$ /sbin/iptables -t nat -F POSTROUTING
 [root@bbuwoo oops-firewall]$ /sbin/iptables -t mangle -Z
 [root@bbuwoo oops-firewall]$ /sbin/iptables -t mangle -P PREROUTING ACCEPT
 [root@bbuwoo oops-firewall]$ /sbin/iptables -t mangle -F PREROUTING
 [root@bbuwoo oops-firewall]$ /sbin/iptables -t mangle -P OUTPUT ACCEPT
 [root@bbuwoo oops-firewall]$ /sbin/iptables -t mangle -F OUTPUT

 커널 2.4.18 이상에서는 다음의 명령도 포함을 한다.
 [root@bbuwoo oops-firewall]$ /sbin/iptables -t mangle -P POSTROUTING ACCEPT
 [root@bbuwoo oops-firewall]$ /sbin/iptables -t mangle -F POSTROUTING
 [root@bbuwoo oops-firewall]$ /sbin/iptables -t mangle -P INPUT ACCEPT
 [root@bbuwoo oops-firewall]$ /sbin/iptables -t mangle -F INPUT
 [root@bbuwoo oops-firewall]$ /sbin/iptables -t mangle -P FORWARD ACCEPT
 [root@bbuwoo oops-firewall]$ /sbin/iptables -t mangle -F FORWARD

 와 같이 해제를 할수도 있다.

 [root@bbuwoo oops-firewall]$ /etc/rc.d/init.d/oops-firewall status
