WebTerminal is not working

Hi,

I've just installed WebTerminal to my IRIS system (Linux SUSE).

I go url:

http://trak01:57772/terminal/

But it just times out

My management portal address is:

http://trak01:52773/csp/sys/UtilHome.csp

The port 57772 is not being listened to [ ss -l|grep LISTEN|grep 57772] 

The doco for WebTerminal says to use this port number in "1.1.3 Launching WebTerminal"

How can I fix this?

Is there some process that needs starting?

Is there further configuration eg. apache web server setup?

Thanks.

This install was done from the *.xml (WebTerminal-v4.9.5.xml) using the Management Portal:

System Explorer -> Classes -> Import

["Compile imported items - Compile Flag cuk]

There were no errors

System Explorer -> Classes with Namespace of USER shows classes

WebTerminal*.cls

System Administration->Security -> Applications -> Web Applications

shows there are entries

/terminal

/terminalsocket
