Automatically update a Linux firewall (ufw) with DNS look up results

[nodecentral]

At last access to a PC !

For those that are able to test it, I'd be interested to hear what you see to be the cause of the difference, it looks to me to be a space is added between the command in the exec node and the payload. (and i can't remove it)

[dceejay]

you are correct.

[nodecentral]

Thanks dceejay

so is that expected then ?

Are you not able to pass command line entries via an inject node ?

[dceejay]

Yes it expected - the parameters for a command are appended using a space to separate them. If you want them as one parameter you need to concatenate them yourself as you have done with the template (or using a function node).
