"Unable to authenticate using any of the configured authentication methods?" to Debian

[A***@zimage.com]

Hi. I just installed Debian v3.1 overnight since I was replacing old
Red Hat Linux 7.1 OS. I installed it cleanly (wiped out everything on a
30 GB HDD). I installed SSH daemon and client from apt-get install.

I cannot ssh (1 and 2) into this box due to these errors:

SSH2 says "Unable to authenticate using any of the configured
authentication methods".

SSH1 says "The server does not support authentication type Password ...
The server supports the following authentications: RSA TIS"

Note this test was just from a Windows box to a Linux box on an Intranet!

How do I make SecureCRT work with this Debian system? I hope I don't
have to upgrade SecureCRT v3.4.8 since I prefer 3.x version (4.x is
bloated to me). I would use PuTTY, but it doesn't have zmodem which only
SecureCRT has. I know I can use SCP, but it doesn't have file transfer
resume availabilty and UI is annoying.


Thank you in advance. :)

Have a look in /etc/ssh/sshd.conf. There are plenty of comments, and you
should be able to work out how to enable password authentication. Try
man sshd.conf for full details.

If you propose doing it via less secure channels, it's a lot better to
use a public key system and deny passwords.

Can't help you there.

I changed no to yes for "PasswordAuthentication" and saved it, but that
didn't seem to do anything.


man sshd.conf came up "no manual entry for sshd.conf". sshd works, but
I see nothing related to your suggestion. :(

How does that work? I use the same computers (e.g., office and friends'
servers) when I use ssh client (command, PuTTY, SecureCRT 3.x, etc.). I
always typed in my username and password in encrypted format.

And restarted sshd ?

How do I do that? In Red Hat, I think I used services command but it
appears that Debian doesn't have this command. Again, I am new to Debian.

You may need to enable keyboard-interactive authentication in SecureCRT
or PasswordAuthentication on the server (but beware that the latter will
*not* use PAM on Debian's current version of sshd).

I set "yes" for PasswordAuthentication line. It didn't seem to help.


Is keyboard-interactive authentication the one where you enter the password
manually in SecureCRT's log in prompt? If so, then that is what I was
doing.

Sorry if I sound like a newbie. I am since PAM and other stuff are
over my head. I am just a user from Red Hat days. I don't even know what
PAM does or if that is any use for home usage. :)

You can do without PAM.
PAM has been in Red Hat since about 5.0, 1998, from memory.

If this is reachable from the Internet accepting passwords
as the sole authenticator may be a problem - someone might
guess it.
