Hi Felix,
Thanks for looking into this.
Do you start server and client on different machines?
Yes, they are on different VMs.
What OS and Java version are you using?
OS - CentOS 7.3, Kernel - 3.10.0-693.21.1.el7.x86_64, Java - OpenJDK 1.8.0_171
(JRE)
To which address does your hostname (on client and server) resolve?
This should not matter because I pass -Djava.rmi.server.hostname=x.x.x.164
switch.
nslookup on both VMs resolves client's hostname to the same IP x.x.x.164
I am using a static port because of firewall rules. Port 50100 is the only one
allowed for result reporting (connections initiated from the server to the
client).
If I switch to random port (=0), the client starts to listen on three ports.
I'm not sure why, I expect it to listen on one port only.

When Secure RMI is disabled, Java is listening on one port only (there are no
log messages like SSLRMIServerSocketFactory but 'netstat -anp | grep java'
shows one listening port).
Does anybody know why Secure RMI needs three ports and insecure one needs only
one?

Hi,
I asked this question on StackOverflow but got no answers or even tips so
sending this to the mailing list.
I am trying to set up remote testing infrastructure with secure RMI using
JMeter 4.0 (one client and one server) but the client won't start because of
'Address already in use (Bind failed)' error.
netstat shows that no process is listening on this port and from the log it
seems that JMeter itself tries to listen on the port more than once (at least
that's how I interpreted the log messages).
Everything works fine if I disable Secure RMI
(server.rmi.ssl.disable=true) Both the client and server use 4.0 r1823414
version.
You can find details and the log here (SO post) -

0-client-with-ssl-rmi
Let me know if you want me to provide any details/settings.

On my machine (server) jmeter prints out the following messages to the
console:

It seems that for my very simple test case there were opened three local ports for RMI.
So maybe it would help to unset the "client.rmi.localport" setting in your
setup?

Felix
