[Netdisco] Bug [ 810939 ] reverse lookup of the sysName.0 field used as IP

[Max B. <ma...@wa...>]

Hey All,

Fixed a bug that may have been wrecking havoc with topology discovery.
The symptom would be something like having a discovered device show
up under the wrong IP address.

See http://sourceforge.net/tracker/index.php?func=detail&aid=810939&group_id=80033&atid=558508
for the bug details.

This is fixed in CVS, or you can wait for the next release.

Summary: (?)
When Netdisco gets an IP address for a device, it has
to figure out wether or not that IP address is the
"main" IP Address.

Take for instance a Router that has an IP address
listed for each of its main interfaces. One of those
might be the main management IP address, or maybe a
completely different one.

Netdisco uses some fields from SNMP To get that, but
would as a last resort do a reverse DNS lookup of the
name stored in the sysName.0 field.

That field is human entered and _very_ error prone.
This could account for a lot of the random topology
discovery errors.

A new option "reverse_sysname" can be turned off if
you want this behavior. Default is off.
