job fails for "restart iptables"
I want to install tigervnc server on a remote server, by following this article:
Add this to the file:
sudo vi /etc/sysconfig/iptables
then restart iptables
-A INPUT -p tcp -m state --state NEW -m tcp --dport 5903 -j ACCEPT
job failed, I checked the system logs
sudo systemctl restart iptables.service
Job failed. See system logs and 'systemctl status' for details.
how to deal with this?
