Hi All,
I'm testing latest netdot-1.0 (from branch netdot-1.0 on
https://github.com/cvicente/Netdot.git), and, I've observed a strange
issue when I add a CNAME to a host entry:
A random DNS Record appears after I've added the alias:
- Two DNS records are shown on my screen:
-- The expected host record (updated as expected)
-- A random DNS record
-- Order may vary.
Did someone else experienced the same?
PS: I've upgrade my database from 0.9.10 to 1.0. Maybe related (broken
dependencies)?
Regards,
Vincent

I've turned on DEBUG mode on htdocs/management/host.html. The

The random second DNS Record displayed is less random now:
- It's the RR element 772
But, this id is the one of the RRCNAME created.

Hi,
I've some device which gives "unknown" index for SNMP object
ipAdEntIfIndex (perl SNMP::Info->ip_index).
"unknown" means that these index do not exist in ifTable.
So, after each time I run ./updatedevice.pl, theses interface are
deleted and re-created on Netdot 1.0.
Is it possible that Netdot ignores such values (ie. do not add an
interface for undefined ifIndex)?
Regards,
Vincent

This small patch seems to solve my issue:

Thank you Vincent.
The patch has now been added (for IPv6 too).
