The problem I am seeing was introduced between 6.4p1 and 6.5p1 (and still exists in 6.6p1). With HostbasedAuthentication/EnableSSHKeysign turned on, I am seeing one of two sets of messages: no matching hostkey found ssh_keysign: no reply key_sign failed and not a valid request ssh_keysign: no reply key_sign failed Then in either case two password prompts: bowman@xxxxxxxxxxxxxxxxxx's password: Permission denied, please try again. bowman@xxxxxxxxxxxxxxxxxx's password: I've used strace and dtrace to watch what files are opened and executables run. All the correct key files are accessed and the correct version of ssh-keysign used. Even the ssh-keysign from 6.5p1 or 6.6p1 works correctly with ssh from 6.4p1. Various systems are affected by this: MacOS X 10.5/ppc OpenBSD 5.1/x86 RHEL 5/x86 Solaris 10/x86 Solaris 11/x64 Ubuntu 12.04/x86 debian 6.0/mips gentoo/alpha gentoo/ppc gentoo/ppc64 gentoo/sparc A few systems are not affected: IRIX 6.5/mips RHEL 5/ia64 Solaris 10/sparc Any ideas on where to look?
