Hello Mans
Yes as far as I can remember they got added by themself, after I added them
into my seed file and did a netmon -y. It took some time but finaly they got
added by NetView itself. The others, that arnt pingable, I had to add them
by myself, over Edit/Add/Object/Computer/Generic. After I added them I
created a SmartSet with them in it, to set their SNMP Community in the SNMP
Configuration (Options/SNMP Configuration) When NetView got them and made a
configuration check they became to servers automaticaly.
I wrote also I got some problems with the Unreachable Status they fell into
a few minutes after they got a SNMP poll, I think my NetView Installation is
messed up, cause on my Testserver it works without a problem now.
If you are able to ping them and the ping command will be open in the
future, take ping, its the better way I think but if you got problems with
ping then you have to use SNMP (the SNMP ports have to be open then).

I hope that helps you

I've been following this firewall discussion and have a similar issue. I
have a few hosts behind a firewall that are pingable and SNMP'able from
NetView. I don't have MLM. How do I get theese into NetView? Is it possible
without MLM?
Michel, You write that the pingable hosts outside the firewall got added bt
themselves. Just like that? And for the others? Did you add them

Hello Jane
I got a similar scenario, I just dont use a MLM at the moment. I got a few
hosts behind a Firewall, some are pingable and some not. The pingables got
added by themself but for the others I used $ before the IP-Adress in the
Seedfile. NetView didnt discover them alone till I added them over
In the next discover cicle it got them and checked it over SNMP (I got the
community name in the SNMP Configuration). Since then it is polling them
over SNMP, well but I still got some problems, they change their status to
unreachable after a few minutes (Polling time is 15min) but as soon as
NetView Polls them again they change back to reachable, I dont know yet why
they are changing to unreachable but at last I got them in NetView. Perhaps
it helps.
