Subject: ipset causes reverse dns lookups?
Date: Mon, 16 Apr 2012 00:26:29 +0100 [thread overview]
Message-ID: <4F8B5925.5020307@wildgooses.com> (raw)
Hi, ipset appears to require a reverse dns lookup for say:
ipset create cp bitmap:ip,mac range 192.168.111.0/24
Why?
In particular if I lock down iptables (-P DROP), then the above command
takes quite some seconds to complete, rather than instantly if I open up
iptables. This is causing me some problems with startup scripts
Am I missing some configuration option? Is this a bug? Why is a reverse
DNS lookup needed?
ipset 6.9.1, kernel 3.2.13
Thanks
Ed W
