Hello.
Is there any method to drop network connection via Dtrace (or other
methods) on Solaris 11.X?
Tcpdrop (or analogue) doesn't exist, from sources doesn't build,
packages for Solaris 10 doesn't downloads.
I have found some advises
http://www.oracle.com/technetwork/systems/networking/tcpdrop-jsp-135583.html
, but it so far from Tcpdrop.
I couldn't find the source code for Solaris tcpdrop anymore, but I'm
pretty sure it will have used the TCP_IOC_ABORT_CONN ioctl. This was
originally implemented for Sun Cluster to speed up failovers, but I see
that Zones is also using it now. It's not a public interface so it's not
described in the manpages, but you can find it in the Illumos source
code, e.g.
http://src.illumos.org/source/xref/illumos-gate/usr/src/uts/common/inet/tcp/tcp_misc.c#42
