Hello, when configuring the OpenSSH to authenticate through pam_radius, I encountered the following problem: The radius server is configured to accept username and generic password, it then generates some textual string as a challenge-request and waits again for username and this time for challenge-response. Pam_radius use pam->conv function, retrieved with pam_get_item(PAM_COM), with challenge-request and type PAM_PROMPT_ECHO_ON, to present the challenge-request to user and to retrieve the challenge-response. OpenSSH...

As an experiment I set up Challenge/response authentication on a Linux system with PAM using a pam_opie module (this module works fine with console logins and su). I can log into the box using the opie password, *but* it does not give me the challenge - which can make things a little tricky :-) I can well believe this might be a...

Hi all, I'm trying to use ntlm_auth as authenticator of the freeradius mschap module. If I use ntlm_auth from command line with username and password, authentication works. If I use the same credentials with mschap on the logs I can see the challenge and nt-response and I can't understand if authentication fails because challenge and response are wrong or because ntlm_auth can't authenticate for a winbind/samba configuration problem. Finally the question: how can I get valid challenge and nt-response strings to pass to ntlm_auth to...

...s (see below), so I can't figure out why the results are bars. I suspect that it may have something to do with the fact that in the data frame where the code worked as intended, the both variables specifying different lines were numeric, whereas in the current data frame one of those variables (challenge) is a factor with 2 levels. Any suggestions for getting this to plot as intended would be much appreciated. Thank you! ************ This is meant to plot a separate line for each subject for each challenge************* for (subj in unique(lab.samples$subid)) { #par(new=T) plot.new() par(mfrow=...

Hi, Has anybody produced diffs for openssh-2.3.0p1 for the rsa keyexchange problem that Core-SDI described ?

This patch (https://bugzilla.mindrot.org/show_bug.cgi?id=1438) creates a kbdint device that provides a server-based authentication mechanism. The server generates and emails you a random string when you attempt to login. You're authenticated if you can correctly answer the challenge. You can use a regular email account, a pager, cell phone or other email capable device to receive the challenge. However, by using a physical device you can receive a one-time authentication secret isolated from your workstation. OBC can be used in conjunction with the "Multiauth" p...

freely quoting from something I posted on #samba a couple of hours ago ########### it appears that challenge/response is actually broken in 4.5.5 Have upgraded 4 dc's and now winbind/freeradius does not work. focused on the radius box thinking that was the problem -- till I finally ran wbinfo -a user%password on all the dc's and they all behaved the same. -> plaintext succeeded challenge/r...

Here is a patch that does TIS auth via PAM. It's controlled by a switch in the sshd_config. You'd use it by having a PAM module that sets PAM_PROMPT_ECHO_ON. eg, you could use it with pam_skey or pam_smxs. The patch is against the 2.9.9p2 distribution. I'm not on the list, a reply if this patch is accepted would be great. (But not required, I know some folks have a distaste for

The Virtual Token (VToken) patch (https://bugzilla.mindrot.org/show_bug.cgi?id=1439) creates a kbdint device that provides a new challenge-based authentication mechanism. The server calculates a challenge from two secrets and a counter. You authenticate by proving by correctly answering the challenge, proving you know the secrets. This creates a software-based token, similar in function to commercial ones, that can be run from you...

Hello, I have to find a solution logon through OpenSSH to OpenBSD machines from anywhere in the world (unsave computers). So I think I must use a challenge-response system with an hardware token that isn't connected to the computer. I do not want to use a RSA ACE/SERVER, so i can't use SecurID ? I can't use challenge response mode with cryptocard, because I want to protect it against an attacker that can break DES. Is it possible to use Ac...

If an ssh1 client initiates challenge-response authentication but does not submit a response to the challenge, and instead switches to some other authentication method, verify_response() will never run, and the kbdint device context will never be freed. In some cases (such as when the FreeBSD PAM authentication code is being used) thi...
