Hi, I would like to report a problem. It seems OpenSSH server does not flush PAM messages unless it is a prompt or the PAM terminates. I've tried it with OpenSSH and Dropbear clients. I tested my own PAM module which simply sends a non-prompting message and sleeps. Used raw C and Python PAM bridge. Both the same results. sshd -V OpenSSH_7.2p2 Ubuntu-4ubuntu2.6, OpenSSL 1.0.2g 1 Mar 2016 steps: - create PAM which sends PAM_TEXT_INFO message and then executes sleep(10) - configure sshd to use it and run the server - try to connect with client - ssh display nothing until 10 sec Is it intentional? I believe it should not be. There are authentication methods which do not need to prompt the user. For example OAuth2 Device code method. cheers Ondrej _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
