Package: openssh-server Version: 1:6.6p1-6 Severity: important On a fresh install of Jessie with systemd and networkmanager in a VM with 3 interfaces, the if-up.d/openssh-server script restarts sshd with every network interface that comes up at boottime.
When these interfaces come up very quickly, this is triggers the default start-limit in systemd, causing sshd to be terminated and the machine in question to become unreachable over ssh. I am able to reproduce this behaviour with 2 ethernet (1 dhcp and 1 static) and 1 tun (openvpn) interface.
