Hi, When running in inetd mode (-i), if stdin/stdout are not an IP socket, sshd will set PAM_RHOST to "UNKNOWN" which causes a reverse DNS lookup by pam that always fails because "UNKNOWN" cannot be resolved. I've posted a possible fix here: https://github.com/openssh/openssh-portable/pull/388 Cheers, Daan De Meyer _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
