Hi All,
When I rebooted the machine, the server is working fine. I have also
noticed that when the recent module behaves unexpectedly, it just adds
one 'last_pkts' entry to the file /proc/net/ipt_recent/DEFAULT for each
host even though there should be more entries (i.e, if the hosts are
connecting for more than one time).
Has anybody experienced it?. So this should be a bug???

Thanks
Sudheer
