Bug#316086: openssh-server: fails silently when -6 given but no IPv6 support in kernel
Package: openssh-server
Version: 1:4.1p1-4
Severity: normal
When the sshd is started with '-6', however the kernel doesn't have
support for IPv6, sshd silently fails to start. Also, the
start-stop-daemon does not report failure.
This could surprise administrators who have been running sshd with the
-6 flag with a kernel that does support IPv6 - because even if IPv6 is
merely enabled in the kernel (but not working or even configured), sshd
will work. When changing to a kernel with IPv6 support (which wasn't
used anyway), "sshd -6" would *silently* stop working.
It should give an error message, and start-stop-daemon shouldn't act as
if sshd was correctly started when it wasn't.
