similar to: [Bug 1364] New: default for ChallengeResponseAuthentication doesn' t match sshd_config

https://bugzilla.mindrot.org/show_bug.cgi?id=2475 Bug ID: 2475 Summary: Login failure when PasswordAuthentication, ChallengeResponseAuthentication, and PermitEmptyPasswords are all enabled Product: Portable OpenSSH Version: 7.1p1 Hardware: ix86 OS: Linux Status: NEW

I was under the impression from the provided distribution version of the sshd_config file that "ChallengeResponseAuthentication" is supposed to default to "yes". Does anyone know if there are any circumstances, such as configure options, that might cause it to default to "no"? Thanks, Richard A. Secor rsecor at seqlogic.com Sequential Logic

I probably should have lead with this, but I did not create or deploy this particular setup, I was charged with keeping it going after the main person left. I have zero experience with Samba or Centrify, or I should say *had* no experience until this. So, I frankly have very little idea of what most of these options are for or why they're set the way they are. I can certainly edit per your

Thank you Rowland! I guess that's part of my confusion, I'm not sure how to best debug where Centrify ends and Samba begins. But if these log.smbd errors indicate Centrify vice Samba, I'm good with that. My global smb.conf is (didn't bother with the commented out stuff): [global] security = ADS realm = <our domain name> workgroup = <our workgroup name> netbios name =

Hi, I'd like to allow PAM authentication only from the local network, and from the Internet only allow public key authentication. A similar-enough problem has been discussed on this list previously: http://www.gossamer-threads.com/lists/openssh/dev/47179?search_string=match%20challengeresponseauthentication;#47179 More specifically, I would like to allow PAM authentication from the

Hello, We'd like to allow passwords only from the local network, and allow public key auth from on-campus or off-campus. The server runs SuSE Linux, and we might do the same on RHEL/CentOS & Mac OS X if we can get it to work. Unfortunately, Match allows PasswordAuthentication but not ChallengeResponseAuthentication. Is there any reason ChallengeResponseAuthentication cannot be

Hi, I'm looking a wiki or share experience for replace NIS authentication by an existing Active directory Server (W2003). The problem is on the management of id and gid. How to move 1000 actual NIS users to AD ? How to keep the same id and gid for this 1000 users ? What's happen with nfs linux server and acess with gid and/id ? Use the same user/password for linux and Windows clients

I'm terribly sorry if this isn't the proper place/method by which to get help with troubleshooting Samba errors/issues, but it's the best one I could find. I have an instance of Samba 4.8.3 running on a Centos 7.6 VM server (kernel 3.10.0-957.1.3), along with Centrify 5.5.2-578, that will allow folks to map a shared drive from their Windows 10 machines generally fine, but quite

I have two domain controllers running ubuntu (12.04 and 13.10) both with samba (4.1.6 and 4.1.7) installed and running (and with sssd on both machines to retrieve uid/gid from AD). I wish to set a share on ubuntu2 in the way so it could be accessible only from ubuntu1 (and by any user from ubuntu1, for instance by local root). I have found this solution though I'm not sure it solves my issue:

You need to disable ?ChallengeResponse? (aka keyboard-interactive) authentication, not password authentication, to protect against this attack.

Hello, I have just installed OpenSSH 4.6p1 and it appears that ChallengeResponseAuthentication is not allowed unless I explicitly set it to "yes" in the sshd_config file. I am using the same config file as I did with 4.5p1 where it was allowed by default. Also, this is OpenSSH package from sunfreeware, but I believe that both versions were compiled with the same options. Is this the

Hi , I have two problems when i went through a) the man page of sshd_config and b) the comments quoted in sshd_config file itself. They are given below. a) >From the man page of sshd_config: "If UsePAM is enabled, you will not be able to run sshd(8) as a non-privileged user." I changed the permission of the hostkeys to a non-privileged user and tried to run sshd alongwith

Hi, Is it possible to have non-authenticating shares on an server with security=ADS ? I have a RHEL server, with Centrify Express, and joined to a domain, but I would like to have a samba share that doesn't request a username/password for machines not on the domain. When I have a plain windows XP machine (not on the domain) attempt to connect, I get asked for a username/password. Is

Hi, For a new samba domain, I need to create users and groups with Unix UIDs and GIDs. In the future, it is possible that there will be a trust with other domains, so I need to take care that there won't be any UID/GID conflict. Also, I assume that in the future Samba will be able to restore deleted objects, so I need to avoid conflicts with those objects as well. This makes me think that a

I have been reading every article I can find to determine how to share home directory redirection across multiple OS workstations. The end result I am looking for is to store user home directory on a member server and allow (in my case) Windows and Linux (Ubuntu in my case) workstations to access their home directory in a single sign (to any OS) situation. (On Ubuntu, leaning toward using winbind

Hi, I'm facing some problems with pxelinux. I have ingetrated it into WDS server. I want to use Network boot all way possible. I want to add Hiren boot disk and NT password editor tools.
