I’ve been using denyhosts for quite some time on my SSH server. I use the sync mode these days – I don’t remember my settings of the top of my head, but I believe I block for two weeks any IP seen making 3 bogus logins within 15 minutes. If the length of my /etc/hosts.evil file is any guide, denyhosts is currently blocking over 3500 hosts known to have attempted ssh bruteforces through the denyhosts sync system.

As for blacklisting or whitelisting IPs with iptables, have fun trying to keep on top of ICANN’s IP registration shifts. Not even ICANN can keep track of who’s using what IP (okay, that’s partially sarcastic). That’s why active defenses such as denyhosts that throw up a defense based on a percieved attack can be easier to manage.

Even breaking it down into reasonably sized chunks, fdupes takes days (maybe weeks, we don’t know yet) to run, but it doesn’t overgrow in memory when presented with huge numbers of files.
(That’s what I was afraid it would do, and fslint choked on our filesystem.)

b=""
fdupes tmp/ --recurse | \
while read f
do
if [ "$f" = "" ]
then
b=”"
else
if [ "$b" = "" ]
then
b=”$f”
else
rm “$f” && echo “Removed \”$f\”"
fi
fi
done

I tried for some time the mainstream distros, called ubuntu, SuseLinux and mandriva what i don’t like of them is the installer. They are again bloated with annoying bugs. Installing a lot of graphical-based config tools pissed me off. Nobody should forgot the power of the command line in Linux.

Slackware is definetely the Rolls Royce of operating systems.
