Hi all,

I have been using the excellent IPTables HowTo (https://help.ubuntu.com/community/IptablesHowTo).

You are supposed to be able to save your current setup using the following command:

sudo iptables-save > /etc/iptables.rules
However when I try this I get the following:

-bash: /etc/iptables.rules: Permission denied
The really strange thing is I can edit the file directly with an editor (sudo vim /etc/iptables.rules).

Any ideas?

sudo runs iptables-save as root, then you're piping the result of the sudo command as your regular user to /etc/iptables.rules. However, you don't have permission to create a file in /etc. This is the only annoying thing about sudo. Try this, instead.


sudo bash -c "iptables-save > /etc/iptables.rules"
