If I switch to the 'Novell BorderManager Proxy Cache Server' the only thing
I see is :
Modified hosts entries in sys:/etc/hosts file are now being used.

It looks like some sort of service is trying to modifying the /etc/hosts
file, but it can't, because it is read-only.
(I did this because the localhost line was tempered with each time I
rebooted the server. '' was deleted)

What can this be ?

nw65sp1 + bm38sp1a is installed on this machine (also imanager 2, tomcat)
