maximum tuple support of hashlimit

maximum tuple support of hashlimit

[Manish Jain]

Hello Friends,

I am using hashlimit with hashlimit-mode as srcip-dstip. My expectation is
to have hashlimit for source-ip and destination ip tuple.

My question is, how many tuple, hashlimit can manage at any instance of
time?

Best Regards,
Manish Jain

You can install the new package next to the old one (f.i. in /usr/local) 
but I would look at packaging the new version. As you have the old 
package, this should be relatively trivial.

Hi,

I'm not entirely sure about your question.  The 'man iptables' shows for
'hashlimit' the following two tunable parameters which may address your
question(?):

       --hashlimit-htable-size num
              The number of buckets of the hash table

       --hashlimit-htable-max num
              Maximum entries in the hash

Cheers,
