To clarify, the sshd listener runs as root and then drops privileges once the user is authenticated.. The issue is specifically the root squash across NFS filesystems which is normally set to disable root privs on the mount (that, and noexec). I.e., even root has no privs to validate the shared key. _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
