Hi

Thanks to everyone who replied..

I am running denyhosts on a machine that is remote and I do all my
work over ssh. The owner of the remote machine just upgrade the
machine I needed to reinstall everything.

When I say denyhosts is not working that means that people are trying
to ssh into that machine as root hunderds of times. Or trying to log
in with any name.

On the old machine. If you tried to log in as root one time, you were
denied access. If you tried to log in with bin you get 10 tries and
then were denied.

Now that is not happening.

As I was remote the first thing I always did was to put my ip address
in hosts allow. In the event I fell asleep and used the wrong
password several times in a row. I have several passwords I use at
different places.

So I launch denyhosts from the command line and it gets a pid and is
running. But, nothing happens. People try to ssh in and denyhosts
never comes up and denies access...

I didn't make a copy of my old config file... So I can't fall back on that.

I don't want to change the ssh port. Not my machine. ...

TIA

Marvin
