nft: don't resolve hostnames by default
This patch changes the default behaviour of nft to not translate IP addresses to hostnames when printing rules if no options are passed. The options regarding translations after this patch are: <no -n/-N> show IP addresses numerically (default behaviour) -n show IP addresses numerically -nn show Internet services and uid/gid numerically -nnn show protocols numerically -N (--reversedns) translate IP addresses to names The idea is to avoid breaking existing scripts that most likely rely on '-n' to save the ruleset, so we reduce the impact of this patch and provide a default behaviour that doesn't generate network traffic when listing / saving the ruleset. Joint work with Pablo. Suggested-by: Patrick McHardy <> Signed-off-by: Arturo Borrero Gonzalez <> Signed-off-by: Pablo Neira Ayuso <>
