I have to clear this up. Netview does NOT use the sysname for labeling or
any
purpose other than the routerSysName field on routers. Openview does.
Netview
does not. And given the amount of garbage I have seen in sysnames, I'm
glad.
Jane, I had a pmr last year for a problem with Netview on NT, and it is
related
to apar PJ27529 (in 6.0.3 and V7.1, I believe) and in the discussions of
that
problem I was told that the gethostbyname() function call will find WINS
entries
in a Microsoft environment. This was causing problems when the nodes were
not in the DNS, and those problems were addressed by that apar. The point
is, WINS will play, but not, apparently, all the way. The discovery uses it
but
the other functions don't. The workaround while awaiting that fix was to
either
put the thing in DNS or stop using WINS.
So if the concern is that Netview is now using sysname for labeling, I
doubt it.
Cordially,

Jane,
This looks somewhat like the behaviour I'm seeing with OpenView (at
least it seems NetView and OpenView are looking to eachothers
functionality....)
In OpenView the rules for labeling devices are:
- use name resolution (DNS, hosts)
- if not available, use sysName
- if not available, use IP
Note, this is only for labeling devices. The Selection Name should be
retrieve via name resolution only, if not available use IP address. I
had the same kind of problems in the past with GUI functions like
pinging the device.
Has NetView (now) the same kind of rules for labeling devices and
setting Selection Names ?
Regards,
Bernard

NetView for Windows 7.1.2 on Win2K SP2. I have 1 IP address in the
seedfile to discover a Compaq box. This address is not in any DNS or
in
NetView's hosts or lmhosts file. The Compaq box is called BACKUP.
When
the node is discovered, the Selection Name is BACKUP. A MIB Browse of
this box shows the sysName is BACKUP. I can only deduce that NV for
Windows will believe the SNMP agent and uses that name in his
database.
The problem arises when you select the node in NetView and try to ping
it, as BACKUP is not resolvable to an IP address.
I think I am sure ???? that NetView for Unix will only use DNS or
/etc/hosts to populate hostname and Selection Name fields, so you
don't
see this conundrum.
Can anyone else confirm or deny what I am seeing? Is this Windows
behaviour a bug?
Cheers,
Jane
