Halloechen!

I try to set up a reasonable configuration for both the client and
the host.

The not-commented-out lines in my /etc/ssh/sshd_config are:

RSAAuthentication yes
PasswordAuthentication no
X11Forwarding yes
UsePrivilegeSeparation no
Subsystem sftp /usr/lib/ssh/sftp-server

Is it correct that the *only* way to estabish a connection is to
append certificates in the authorized-keys file?

Actually I also need the possibility of passwords. Would
PasswordAuthentication yes
a clean and secure way to do so? In particular, the comment in
sshd_config says

# To disable tunneled clear text passwords, change to no here!
PasswordAuthentication no

which sounds not very encouraging. I thought ssh prevented
passwords fom being sent in clear text.

Thank you!

Tschoe,
Torsten.
