IPs for "hostname" in Data Center Expert

This question was originally posted on DCIM Support by Dominic Brasted on 2020-01-24


I know it's been asked several times on here but the answer "make sure it's in DNS" isn't always sufficient.

I have about 150 devices in DCE (7.6.0.114). All of the devices are in DNS, both forward and reverse lookup. 8 devices won't show their hostnames in DCE. I can use the DCE troubleshooting tool to do a reverse lookup on those 8 device IPs and it comes back with the right hostnames. As far as I can tell they're set up identically to my other similar devices (most are Netbotz) that do show their hostnames correctly. E.g. I have other Netbotz with the same firmware version and settings, and they show the hostnames correctly.

What else can be done to make DCE show the hostnames?

I am using the same DCE version and had similar problem in the past. My suggestion:

  • Try to reboot the DCE server. Reason: when I "newly" created DNS A and PTR records, DCE did not updated the hostname field even though I waited 2-3 days. After server reboot it was automatically updated. That would be a good feature from the developers to create a DNS service restart/refresh button, isn't it?
  • I experienced if more then one DNS PTR (reverse lookup) entries created for the same IP then DCE did not shown any of that. Try to check if you have the problem (the DCE web network troubleshoot / Resolve Host feature)

Thanks for the reply. Do you recall whether you had particular problem with Netbotz appliances? DCE seems to have no trouble updating the hostname for my UPS and other devices without a DCE restart. It's only (some of) the Netbotz that aren't showing correctly. I've checked the reverse lookup, there's only the one entry for each device and it works fine in the network troubleshooting tool (i.e. DCE can resolve the hostname without issue).

Dear Dominic Brasted,

From your question:

I can use the DCE troubleshooting tool to do a reverse lookup on those 8 device IPs and it comes back with the right hostnames...

Try a similar troubleshooting, but from your 8 problematic NetBotz appliances. To do this, as indicated in post , you must go to the special web-page http://<IP_NetBotz_app>/pages/support.html :

  1. spezialist, system and radio engineer

    Dear Steven Marchetti,

    To enable telnet hit the web interface and append /enabletelnet after the IP like this:

    http://192.168.1.100/enabletelnet

    ...

    If it works, we can also try using:

    http://<netBotz_IP>/unconfig

    I am very interested in this topic. Where it is possible to learn in detail the list of all possible web-commands for use with NetBotz-4.x appliances?

    Very thanks for support.

  2. Steven Marchetti

    spezialist,

     

    There is no list of URLs available. I am aware of a few such as the ones you mentioned:

    /unconfig

    /resetconfig (same as above but resets IP too)

    /enabletelnet

    There is also the MIB:

    /netbotzv3.mib

    There are also some commands that are bundled under a single page and likely what you're most looking for:

    /pages/support.html

     

    Steve

Try it please.

With respect.

Thanks very much, that's a very useful link to know. I tried it on one of my Netbotz and nslookup works just fine, it can find the hostnames of all my troublesome Netbotz without any issue.

Do you have any other suggestions on how I can get the hostnames updated in DCE correctly?
