No, this is not correct.

According to Phil Schwartz:

"Suspicious logins are based on DenyHosts observing that a failied login 
exceeded the threhold but then was able to login based on the 
user/ip address."

Denyhosts is designed to detect brute-force attacks, so whitelisting seems not 
only like a pointless workaround, but also bad system security. This is 
especially the case if one of the machines on the whitelist ever gets 
compromised.

In my case, the behavior of denyhosts changed around May 26 of this year 
without me changing any of the configuration files. I have checked my package 
logs to see what new packages were installed around that time, and I'm stumped 
to find anything that could be causing this problem.

I've also tried uninstalling and reinstalling denyhosts (including deleting 
/var/lib/denyhosts), zapping /var/log/auth.log, and all of my logins are still 
marked as being suspicious.

So either:

1. It was working properly for several years and then it became broken; or

2. It was broken for several years and then it started working properly.

If anyone has any insight into getting denyhosts to work properly, and not a 
workaround with logcheck or whitelisting, I'd appreciate any tips.

Thanks
