Not really. The only way netmon can go off without the seedfile controlling
it is if
a) the ovsuf entry for it has been damaged and no longer passes that
parameter
b) the file referenced in the parameter is not available or empty
c) you start netmon by saying 'netmon' (no parameters) rather than 'ovstart
netmon'

I am so proud that you had a backup, Mark.

Subject:  [NV-L] Unbridled Netmon



Hi All,

I'm hoping someone here can confirm or refute my suspicions regarding the
cause of the following symptom(s) in my AIX 4.3.3, NV6.0.1 environment.

Recently my Netmon took off on an unbridled (sans seedfile) voyage to
discover the world, earning me the new title of "Christopher Columbus",
apparently choking our DNSs and firewall in the process, and discovering
way
too much undesirable stuff.

I believe I had stopped Netmon and absentmindedly left it down.  A collegue
noticed Netmon wasn't running and restarted it after becoming root with
"su", not "su -".  Root's .profile sources the Tivoli environment, as does
this user's .profile.  I suspect that "su" didn't get the Tivoli
environment
set, thus netmon didn't know to use the seedfile and was able to run wild.

Are my suspicions correct or even on track?

BTW, after reigning in Netmon I cleaned up the mess by restoring a recent
tarball of /usr/OV/databases.  Stuff DOES happen.

Thanks in advance.
