[Dnsmasq-discuss] Dnsmasq hard limit

2010-09-27 Thread Gabriel Dungan
Greetings,

I've been looking at dnsmasq and pushing to my peers as a replacement for a
custom distro. The Distro is currently using dnsmasq for dns proxy caching
but not as a dhcp daemon. The question that comes up, is if the Hard limit
you talk about in the faq is an actual hard limit, or by the use of the
flag, one is able to set it to a higher limit.

I know that your earlier versions were locked to 100, the default now is
1000, and the verbiage suggests it's settable to anything one could need.

I know the idea of dnsmasq is to provide services for the smaller market.
However there was a concern that if some one had a medium to large business
used our distro, if they had 2000 client machines, it wasn't going to
bomb..  (Hardware, memory, disk space, et al aside)

Would you mind going thru that, and letting me know your opinion on such,
and what the Hard limit is..

Regards

This is the limit on number DHCP leases? 1000 is just the default, you
can increase it easily by setting dhcp-lease-max in /etc/dnsmasq.conf,
there's no hard limit. The practical limit depends on how big the lease
file is and how often it's written. On server hardware, with plenty of
memory and fast disks, and with reasonably long lease times, much more
than 1000 leases should be fine.

Cheers,

Simon.
