In gdb I see it gets to read -s
case 's':
sflag = optarg;
break;
It realizes no more options are there and then ends at
} else if (argv[0] && argv[1]) {
host = argv[0];
uport = &argv[1];
if (pflag || sflag)
usage(1);
And sflag is set, so it reports usage and exits.
The particular check in this path of pflag/sflag didn't exist back then.
I found this comes in via a patch
debian/patches/misc-failures-and-features.patch
That was in Debian and Ubuntu since late 2016
This patch was modified by:
commit 2ebffb014c830e49f6fad600c59cc1b82fe356a4
Author: Guilhem Moulin <guil...@debian.org>
Date: Sun Dec 3 22:58:11 2017 +0100
Allow usage of -s with -l for consistency with netcat-traditional.
Since then this is also in Debian.
