When Tomcat starts, it listens on TCP port 8005 (this is default, could 
be changed in conf/server.xml) for SHUTDOWN command. When you call 
shutdown script, you are actually sending SHUTDOWN command to TCP port 
8005. If you get "Connection refused" it merely means that your shutdown 
script is unable to open TCP connection to port 8005.

Although it is generally possible that firewall blocks TCP port 8005, it 
is unlikely, since the shutdown script and Tomcat process listening on 
port are usually at the same machine. In your case it is even more 
unlikely, since you didn't have any problems with shutting down Tomcat 
before you installed Sakai webapp.

My guess is that there is something very wrong with your Sakai 
deployment, which caused Tomcat not to start properly, and therefore, 
not to start listening on TCP port 8005. With the information you 
provided, it is hard to say what is wrong. You should inspect logs in 
order to get a clue. I hope you have access to logs folder on the remote
