Been there. Done that. Read sysctl(8) before posting the first time.
# sysctl -a | grep kern.maxssiz
#
No output. Did *you* try your suggestion before posting?
sysctl(8) says:
-a List all the currently available non-opaque values.
This option
is ignored if one or more variable names are specified
on the
command line.
...
-o Show opaque variables (which are normally suppressed).
The for-
mat and length are printed, as well as a hex dump of
the first
sixteen bytes of the value.
-a didn't do the job, and neither did -o, so I asked here.
