     The seedfile is part of the daemon configuration meaning that whenever 
     the daemon is started it checks its config and loads the proper 
     settings. So your netmon daemon must have used the seedfile or you 
     have a bigger problem.
     
     What I am guessing is that you did not limit your seedfile to only the 
     devices you listed in it. Basically, you should have listed all of 
     your devices one per line and then at the end of your seedfile place 
     something like this:
     
        3.3.3.*
     
     This will tell the netmon daemon to stop looking for devices once it 
     hits this bogus address.
     
     Hope this helps...

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.
