...iously pointed out. Now, about the solutions in the other thread: - Damien Miller suggested patching sshd. That would be ok for me, but only if that's what makes the most sens: that is, my policy is too specific and useless or unadvisable to others. - Damien Miller also suggested turning off KbdInteractiveAuthentication inside match, and, - Darren Tucker suggested turning it off outside and on inside, But, I tried these options: a) ChallengeResponseAuthentication yes #KbdInteractiveAuthentication yes Match Address !10.0.0.0/8 KbdInteractiveAuthentication no - keyboard interactive auth from the Internet isn&...

Hi, I'm using 2-factor authentication (pubkey+googe_authenticator) and have an issue with rsync. It's configured to use pubkey to authenticate to server so when google_authentication is bypassed by not creating .google_authenticator file for particular user (thanks to nullok option in PAM) it still sends to stderr "Authenticated with partial success." message although it

Hi. I wonder if it would be possible to implement support for a user-specific sshd_config. The primary reason is that I would like the ability to specify that I'm only allowed to login with a key pair, even though the system-wide sshd configuration still allows passwords for other users. Of course, a user-specific sshd_config file should not be able to break the security policy of the

[Not subscribed to this list, so please respond directly if you need to speak to me] In man5/sshd_config.5, a permissible keyword in a 'Match' block is missing. It currently lists only: AllowTcpForwarding, Banner, ForceCommand, GatewayPorts, GSSApiAuthentication, KbdInteractiveAuthentication, KerberosAuthentication, PasswordAuthentication, PermitOpen, PermitRootLogin, RhostsRSAAuthentication, RSAAuthentication, X11DisplayOffset, X11Forwarding, and X11UseLocalHost. >From recent testing in setting up a chroot'd SFTP-only environment (thank you for that!), the following is also pe...

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

...mentation function a few lines above, it checks options.challenge_response_authentication to decide whether to actually proceed with the authentication. This results in the behaviour of "ChallengeResponseAuthentication no" also disabling keyboard-interactive authentication, even if "KbdInteractiveAuthentication yes" is specified. I'd call this a bug, but other places in the source code have interactions between these options, so I'm not sure whether it is intended or not. Also, the KbdInteractiveAuthentication option isn't explicitly documented in the manpages, so I'm unsure if it...

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

Hi, I would like to do some development on the securid patch to get it to display the passcode prompt when users log in with securid on ssh. Can anyone tell me which scripts currently handle the logon/password prompt in openssh please? Thanks, JS. _________________________________________________________________ Join the world?s largest e-mail service with MSN Hotmail.
