Hi All. This patch calls pam_chauthtok() to change an expired password via PAM during keyboard-interactive authentication (SSHv2 only). It is tested on Redhat 8 and Solaris 8. In theory, it should have simply been a matter of calling pam_chauthtok with the PAM_CHANGE_EXPIRED_AUTHTOK flag, it'd only change the password is if it's expired, right? From the Solaris pam_chauthtok man page:

Hi. It would be of utmost utility if there were a way to cause the sshd "banner" configuration setting to only print the banner in certain circumstances. What I'm actually after is avoiding printing out the banner for non-interactive sessions, so that if I run "ssh somehost ls" I don't get the login banner, but if I just type "ssh somehost" I do (at

When we installed OpenSSH 2.1.1p4 on our Solaris systems, our users noticed that it did not honor password expiration consistently with other Solaris login services. The patch below is against OpenSSH 2.2.0p1 and adds support for PAM password changes on expiration via pam_chauthtok(). A brief summary of changes: auth-pam.c: * change declaration of pamh to "static pam_handle_t *pamh",

Ok, so, things are complicated. The PAM standard insists on password aging being done after account authorization, which comes after user authentication. Kerberos can't authenticate users whose passwords are expired. So PAM_KRB5 implementations tend to return PAM_SUCCESS from pam_krb5:pam_sm_authenticate() and arrange for pam_krb5:pam_sm_acct_mgmt() to return PAM_NEW_AUTHTOK_REQD, as

Hello list, I'm trying to reuse a fairly old PC based embedded system. It has no video output at all, no VGA, nothing older, and no keyboard / mouse connectors. The console is on a standard RS232 interface, including BIOS output and the minimal BIOS loader. The BIOS emulates / redirects text output to and keyboard input from the console RS232 interface, but unfortunately, this emulation

Hi, I want to write pam module for challenge response based authentication with keyboard interactive authentication method on both sshd (server) and ssh (client) side. How should I write the pam modules. What is the general protocol between pam functions and the calling functions. What information does the sshd gives to the pam module how can the pam module send the information back to

Hello, I have recently downloaded and compiled openssh-3.7.1p2 on both HP-UX 10.20 and HP-UX 11.00. The compile went fine. Logging in on the system used for the build works fine. However, logging in on a different system (where the newly compiled openssh is installed) results in the following error: Permission denied (publickey,password,keyboard-interactive). I have tried several things I

Hi all, I noticed that support for the keyboard-interactive user authentication method is mentioned on the "todo" list in the README.openssh2 file. Is anybody actively working on this? Thanks, Mike -- Michael Kiernan mkiernan at avantgo.com +1-650-638-7581

Hi All. Today a patch was commited to OpenSSH that performs PAM password changes via SSH2 keyboard-interactive authentication. I should work fine with privsep, which some of the other solutions have problems with. While the patch itself is relatively small, it's bigger than it should have been due to differences in PAM implementations. I encourage anyone with a interest in this to try

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