Auditd seems to miss accept syscalls from ssh on Ubuntu 14. I tried

2.3.2 and 2.4.5 of the daemon with kernel versions 3.13.0-96 and 4.4.0-47.
In all cases the accept syscall (43) failed to show up until after I
restarted the ssh daemon. It's especially weird because I don't see this
problem on Ubuntu 16 (4.4.0-38). Any thoughts about why I am seeing this or
where to look?
I found a similar question in the archives, but it seems to do with the
architecture size and not OS versions:

I also posted this question on Stack Overflow:

I'm not really very aware of what Ubuntu is doing wrt to their default
audit configuration, but this really sounds like you need to add
'audit=1' to the kernel command line.
