Problem with stopping LS server in Linux

[quanhm]

I managed to set up a LS server in Linux and it run well, but when I execute the shells to restart or stop it emits an error as follows :

Stopping Lightstreamer Server...

Do I miss something while installing LS server ?

The restart and stop scripts try to connect to Lightstreamer Server on port 9999 (or the port specified in the jmxmp_connector_port element within lightstreamer_conf.xml). Perhaps you have some personal firewall blocking this connection?
