systemctl disable firewalld systemctl mask firewalld Restart iptables service iptables restart Save service iptables save and reboot. Redirecting to /bin/systemctl start rviceįailed to issue method call: Unit rvice failed to load: No such file or directory. Since you have installed the iptables, try to disable and mask the fiewalld service and check once. Loaded: not-found (Reason: No such file or directory) Redirecting to /bin/systemctl status rvice If you want to reload IPtables to validate changes you have just made you can also restart Apache with the command lines below: /etc/init.d/apache2 stop /etc/init.d/apache2 start These command may vary depending on your flavor of Ubuntu, and eventual modifications that may have been made previously. For other actions, please try to use systemctl. The service command supports only basic LSB actions (start, stop, restart, try-restart, reload, force-reload, status). what's wrong with it? What am I doing wrong? # ifconfig/sbin/service iptables saveīash: ifconfig/sbin/service: No such file or directory I am trying to open 80 port for httpd service, but something wrong with my iptables service. We can, however, change this behavior and add a new policy for any of these chains: iptables -policy FORWARD DROPĪs a result, iptables will drop all packets which are not locally consumed by the kernel: $ iptables -L -vĬhain FORWARD (policy DROP 0 packets, 0 bytes)ĥ.2.I installed CentOS 7 with minimal configuration (os + dev tools). So by default, iptables allows all input and output packets to go through. Pkts bytes target prot opt in out source destinationĬhain FORWARD (policy ACCEPT 0 packets, 0 bytes)Ĭhain OUTPUT (policy ACCEPT 0 packets, 0 bytes) Therefore, the kernel will use these chains if the data packet doesn’t match any custom rule: $ iptables -L -vĬhain INPUT (policy ACCEPT 0 packets, 0 bytes) There are certain default chains in iptables that don’t declare any matching expression.
