    I have never experienced the problems you mention. As I type this, I am
    logged into my Debian box at home (running etch rather than sarge, but it
    ran sarge before its release as stable and I also had no problems) with
    PuTTY on Windows.

    That said, here are some ideas on diagnosing your problem. First, edit your
    /etc/ssh/sshd_config and change the LogLevel to DEBUG.
    You should see a line that says that the SyslogFacility being used is AUTH;
    in a normal configuration, this means that sshd messages go to
    /var/log/auth.log and you can grep that file for sshd. Once you've
    restarted sshd after changing the log level, run (as root):

    tail -f /var/log/auth.log | grep sshd

    This will show you only sshd messages. Now attempt to connect with PuTTY.
    You should see a bunch of output which, one hopes, will shed some light on
    the subject. If it isn't clear to you what the problem is, paste that
    output into your next message.

    Also, PuTTY itself has an Event Log accessible from its system menu. That,
    too, may be informative.
