[clue-tech] kerneld is removing my loaded kernel modules!

I would think that you just modprobe them (without -k).  But I can't say 
I've ever seen a module autocleaned.

How do you get them loaded in the first place?

I don't think I've used the ftp modules specifically but the nat and 
conntrack modules have always loaded for me whenever I've put in an 
iptables rule that used -t NAT.

That's what I get currently, though this is 2.6 (I don't have iptables 
on any 2.4 boxes).

The 2.6 kernel doesn't do autoclean--perhaps you could upgrade to that.

Are you doing anything with iptables when this happens, or is it just 
sitting there filtering?

Sorry I don't have better suggestions.
