Just to throw out a no-brainer, do you have "sshd server configured with
tcp_wrappers support enabled" (from
http://denyhosts.sourceforge.net/requirements.html)?

Turns out some servers here - like the one i tested - were.  But we have
some using the debian package

Package: openssh-server
New: yes
State: installed
Automatically installed: yes
Version: 1:4.3p2-5

and they don't!  The test fails on these and only these.  So this
version didn't have 'wrappers compiled in.  Aaargh...

thanks! teach me to not test every host.  Looks like i'm rolling my own.

Hey all,

I'm running
OpenSSH_4.3p2 Debian-2, OpenSSL 0.9.8b 04 May 2006

and using DenyHosts
( http://denyhosts.sourceforge.net )

to stop dictionary attackers, worms, and other pests.  However, i see
denyhosts adding entries to hosts.deny at say 16:45, and the connection
attempts from that same IP continue for a good 5-10 minutes - on the
same host, random login attempts are still being logged uninterrupted to
16:50 or :55.

Does sshd not honor hosts.deny entries?  Is it my version of ssh?  I've
tried both ALL: and sshd: entries in hosts.deny, with no apparent
change.  Any suggestions appreciated.

Thanks!
