I could be wrong, but I don't think the sockets API makes this
possible -- RST segments are normally only sent by the kernel upon
receiving a segment that doesn't match the current state of the
connection.
Since Go uses the kernel sockets support, there's probably nothing that
can be done about this with Go.
You'll need to work at a lower layer:
- the firewall code is normally able to send RST segments; under
Linux, you can achieve that with
iptables ... -p tcp ... -j REJECT --reject-with tcp-reset
- you could probably use raw sockets to inject RST segments, but that
would require building your own TCP header and running your program
as root. It's probably easier to interface with the firewall.
As Jesper said, it would be helfpul if you told us what you're trying to
achieve.
