What rev of OD ? In 7.0 there is not a separate OD Admin (it is integrated with TS Admin)Are you certain it is running ? From what I can tell, it is not in any of the etc files (deploy.cfg etc)
you do not need snmp (or likely not)It is in the AdminServier/servletd/conf/server.xml file
Thanks very much mate. The person who installed this had changed the port to 8082!!!
They may have done so because the default port might have been in use by some other application (like anti-virus software) - so check carefully before trying to change the port back to its default.
