Package: openssh-client Version: 1:6.7p1-3 Severity: normal Tags: upstream Hi,
The return codes for ssh-keygen -F are undocumented. In stable's version (1:6.0p1-4+deb7u2) you get: mcv21@pick:~$ ssh-keygen -F foo.invalid -f ~/.ssh/known_hosts mcv21@pick:~$ echo $? 0 But in testing's version, you get: root@boarstall:~# ssh-keygen -F foo.invalid -f /etc/ssh/ssh_known_hosts root@boarstall:~# echo $? 1 I can see nothing in upstream changelogs to flag this change, and the manual for ssh-keygen doesn't state its return codes. So code relying on the old behaviour (0 return value, no output ==> host not in known_hosts, otherwise all is well) now fails as ssh-keygen is returning non-zero. I think this is a bug, and that the behaviour in this case should be restored; even if not, the new behaviour should be documented.
