Package: sssd-common Version: 1.12.5-3 Severity: serious Apparently sss_ssh_knownhostsproxy breaks "ssh -4 host.example.com". No connection.
ssh -4 -o ConnectTimeout=10 r...@host.example.com Connection timed out during banner exchange If I use host's IPv4 address or omit the proxy then there is no problem. This bug is serious. The reason for "-4" and "-6" is to explicitly work around network problems. openssh-client is version 6.7p1-5+deb8u1. Please reassign, if necessary. Regards Harri
