need for something like samhain with dialup?

[Douglas Tutty <dtutty@porchlight.ca>]

I'm seeking a quick word of advice:

For simple dial-up intermittant internet access, running amd64 Etch, is
there any need for something like samhain or is that just overkill?

If there is, is samhain the best or is there something better?  

I don't have anything listening on outside interfaces, currently have
ipmasq installed and will set up shorewall to replace it.

Thanks,

Doug.
