Description Justin Sherrill 2010-05-20 17:41:20 EDT
Currently the default configuration is for tomcat to listen on all interfaces for port 8080 and 8009, but this isn't needed.

We need to change it in teh installer to just listen on localhost, especially now that we are moving the stored procs to a localhost accessible xmlrpc handler.
Comment 1 Jan Pazdziora 2010-08-31 11:21:10 EDT
Addressed in Spacewalk master, 78a69fafa3e3d97535cf7efb6727bb26198d8bfe.
Comment 2 Jan Pazdziora 2010-08-31 11:22:41 EDT
One way to verify the fix is to run

ps axuw | grep tomcat | awk '{ print $2 }' | while read i ; do lsof -nPp $i ; done | grep TCP

and check that all TCP LISTENs have 127.0.01 and not a star (*) there.

Verified in stage.
