getting "packet counter not numeric" when setting iptables dnslimit

  • 772

I get this exact error:

iptables -A INPUT -p udp --dport 53 --set --name dnslimit
iptables v1.3.5: -c packet counter not numeric

What am I doing wrong?

iptables

  1. You are failing to provide packet and byte counts to the --set flag, which is being interpreted as an unambiguous match for --set-counters, aka -c. From man iptables:

    -c, --set-counters packets bytes

    This enables the administrator to initialize the packet and byte counters of a rule (during INSERT, APPEND, REPLACE operations).

    My guess is that you're trying to use the recent module, in which case what you're really doing wrong is missing the -m recent. But that's only a guess.
