I just got port scanned...

[adler at stephenadler.com (Stephen Adler)]

Guys,

I could see an odd pattern in my network usage, (I run the system 
monitor gnome panel applet,)
and my disk was making odd repetitive access noises. I then checked my 
log files and lo and behold,
I was being port scanned by someone from 200.21.18.136. What's the 
mechanism by which
a rule gets added to my firewall or hosts.deny file when I get port 
scanned? Also, I noticed that
a file /var/log/btmp got rather large. What tool do I use to examine the 
content of /var/log/btmp?

Thanks in advance.

Cheers. Steve.
