Script to query DHCP server for computer name if IP address is known

I run vulnerability scans of my company’s network. After scanning my network I have a lists of IP addresses with no computer names. Most of them appear to be VTC or telephony
systems so they are don’t respond to NBTSTAT. I can manually
find them in my DHCP server but the lists is quite long. Does anyone know of a script that I can run against the IP address lists that would query the DHCP server and return the associated machine name that is listed in the DHCP server? 

Surely you have a DNS server and this is all set up and you're not relying on NetBIOS broadcasts or a WINS server?
PowerShell:
([Net.Dns]::GetHostByAddress("123.123.123.123")).HostName

  • Unable to get ip address from DHCP server for Aironet 1130AG Access Point

    I have a network in which DHCP server is enabled. I have read the installation guide also there it is mentioned that 1130G Access point will not have any staic ip assigned to it.So it will automatically get the ip from the DHCP server from the network. I have connected that from the network but it is unable to get the ip address from the same. The same thing i have configured in the netgear it is coming fine. I have seen the sonic wall and used the IPSU tool also from checking the ip address from Mac Address but i am not able to get the same. Please provide me some tips to check where i am wrong in configuration because the first web page also not coming because of the ip address.

    narendra,
    I would suggest that the AP be connected to a laptop or desktop pc that would run a local dhcp server with a small scope setup...plenty of free ones on the web(this pc would obviously not be connected to your currnet network). This way you can watch the dhcp server hand the AP it's address (this can take a few minutes). Once you have the address use it to access the GUI and give the AP a static address (I find it good pratice to give all my autonomous AP's static addresses for ease of troubleshooting)...Hope that helps.

  • IPhone Wi-Fi sync stuck at "Looking for [computer name]"...

    Hello,
    For the longest time my iPhone 6 has not been able to sync with iTunes wirelessly, despite the fact that the phone clearly knows if iTunes is running or not. I'm running iOS 8.1 on my iPhone and iTunes 12.0.1 on OSX Yosemite 10.10.
    I have confirmed that the phone does know when iTunes is running on my Mac. When iTunes is running and I go to Settings > General > iTunes Wi-Fi Sync on my phone, the "Sync Now" button is enabled, but when iTunes is not running the button is disabled out with a message saying "Sync will resume when "[computer name]" is available."
    When iTunes is running and I tap "Sync Now" from my phone, the button changes to "Cancel Sync", and a message below says "Looking for [computer name]...". That lasts for about a minute, and then the screen reverts back to its previous state (with the "Sync Now" button). The actual syncing never occurs.
    I've checked the firewall settings on my Mac to make sure iTunes is set to allow incoming connections, and it looks like everything's configured properly.
    Has anyone run into this issue before? I'd greatly appreciate any help!
    Thanks!
    Ryan

    Well, it happens often and, as to me, I don't think it's an issue of Apple, OS or whatever else, rather than a Wi-Fi nowadays technology itself: let's be hones — even though it is popular it is not that good. But, getting back to your question — my solution (the one which works for me) is easy and quite — no hassle with password, nothing...
    All you need is to renew lease of your device over the wi-fi network. Go to the Wi-Fi settings, click the blue arrow to get to the settings of the current network and click the renew lease button; launch iTunes — it's there your iDevice.
    Personally, I've got two of them — and from time to time I'm renewing the lease — that solves mentioned issue.
    With the Kindest Regard,
    Yours Aunt Deena

  • Using one controller as primary DHCP server for 2 or more controllers

    Here's my setup
    2 - 5508 controllers (40 APs per controller) running 6.0.196.0 (100 user license per controller)
    about 80 mixed - 1142 and 1252 APs, trying to put 40 APs on each controller
    One subnet connects two controllers together on the management interface on port 1 on both controllers. 10.x.x.x addresses.
    Port 2 on each controller (LAG not used) connects to a DMZ via dynamic interfaces for user traffic, 172.x.x.x addresses.
    I want to use one controller for all clients to get their DHCP addresses from (no matter what controller their AP is on)
    as a primary DHCP server (controller A as primary), then i'd like to point the clients to the other controller (controller B) to be used as a backup DHCP server in case Controller A fails. Also, the APs are setup to have the correct primary and secondary controllers under their high availability setting as well as the mobility group information.
    I want to avoid splitting my DHCP scopes between controllers, and I don't have a DHCP server dedicated to this project, so the 5508s should be able to do the job. Or at least I thought.
    When configuring the controllers with the proper DHCP scopes, this only seems to work for clients connecting to controller A. Clients on controller B don't get an address from controller A when pointing to that controller, in fact, the wierd thing is that debugging shows DHCP requests going out of port 2 (DMZ traffic) instead of port 1 (management) on controller B. Shouldn't they be going out of the interface that is specified with the DHCP configuration in the dynamic interface? And I don't have "override" turned on in the WLAN configuration so the DHCP server should be taken from the dynamic interface that the user resides on.
    Mobility groups are configured correctly between the two controllers and both the control and data paths are up between the two controllers. Another wierd thing, both controllers management interfaces are on the same subnet, no acls or filters, when the mobility groups are configured, controller A can ping controller B, but controller B cannot ping A. The status still shows as UP/UP in the mobility members windows, but they use mPing which seems to work fine. Remove the mobility group configuration and ping works just fine between the boxes. I don't know if this is related to my DHCP issues, but it would seem that if I put the controller A's management address in the dynamic interface configuration for DHCP on controller B, my clients on B should get an address from A's DHCP pool. Controller A's dynamic interfaces all point to controller A's management interface and they work just fine.
    I'm trying to load ballance my AP distribution between two boxes, and I'm also trying to have some controller redundancy.
    Controller A works just fine, it's in production. Trying to add another controller B to talk A for DHCP is the issue.
    Anyone have any clues?
    -Blair

    I guess i was under the impression that when mobility groups were cofigured, the lease time, along with other client information (mac address, IP address and such), would replicated from one controller to the other controller over the EoIP tunnel.  If that's not the case, then obviously I'll have to look elsewhere.
    Also, does this mean that it will not work, or just that it's not recommended.  If it does work and I have to fix something, at least I can move on with my testing, all while pursuing a DHCP server.  It doesn't sound like using an AP as a DHCP server is any better than using the controllers for that same purpose.
    Thank you for the quick response.

  • Looking for my computer name and mac address.  Where do i find them?

    I think this should be straightforward.  Where would I find my Mac Address and name of my computer?  I want to tether with my phone and need to give my phone this info.

    Your Computer Name is found in the Sharing preferences at the top. For your MAC address open Network preferences, select your desired port such as Wireless then click on the Advanced button. Click on the Hardware tab. You will find it there.

  • DHCP server for SnowLeopard

    Hey Guys,
    is there any DHCP server application for SL?
    Want to share the Internet through my laptop and not to set up IPs manually.
    Thanks in advance.

    Jeff: I do use Wi-fi router for this purpose at home and office but there is some situations (especially when you're traveling) when I have a wireless network only. I have a device which I carry with me and want to use but it has a wired ethernet only.
    John: thanks a lot for the direction. I've managed with the problem.
    1. en0 is reconfigured as 'DHCP with a manual IP' - at the least got an IP on laptop and bootpd started to listen the network ('netstat -an' shows open UDP 67 & 68)
    2. got 'bootpd[105]: DHCP DISCOVER [en0]:' in my syslog; no replies from the OS X (it's weird)
    3. changed 'replythresholdseconds' from 4 to 0 (details - http://www.macosxhints.com/article.php?story=20071223001432304).
    4. got DHCP REQUEST in syslog
    5. enjoying DHCP and the Net access from my second device.

  • AirPort Express DHCP Server for distribution of IP-addresses?

    Does the AirPort Express have an DHCP server that distribute local IP-addresses like other Wi-FI router does? If so, how do I set it up in the AirPort Utillity?

    +Seems I cant force it to only use a specific subset of the IP address range?+
    That would be up to the Netcomm router to provide the IP addresses to be used. I'm not familiar with Netcom, but a router with the type of capability I was thinking of could be configured to provide a certain range of IP addresses to a given device based on the MAC address of the device.
    The additional information that you just furnished indicates that you probably have a basic featured router designed for home network use that would not have this type of capability. In that case, the AirPort Express would not be able to be configured to Distribute a Range of IP Addresses. It would have to be configured as a "bridge" on the network and receive IP addresses from the main router.
    Or, the AirPort Express might be able to distribute the IP addresses that you want if you configure it to Share a public IP address. The rub here is that you will have what is known as a Double NAT on your network. You'll have two devices handling DHCP on the network when there should only really be one. It may or may not function correctly as this is not a recommended configuration.

  • ASA as DHCP server for WLC2106 and LAP

    Hi,
    First off i aplolgize for asking something that seems to have been asked before but i am getting conflicting answers and wanted someone to give a definitive answer.
    Setup:
         ASA5505  ---------------- WS-C3750G -----------------WLC2106  -------------------------------AIR-LAP1131
    (DHCP SERVER)           (simple config)          (dhcp proxy disabled)           (is requesting dhcp from ASA)
    ASA5505 - ASA 8.2(1)
    WLC2106 - 7.0.98.0 (tried 6.0.99.4 as well)
    AIR-LAP1131 - 12.4(23c)JA
    Problem:
    The ASA5505 is giving addresses to multiple devices, i tested it with the AP plugged directly into the ASA and it worked great.  The problem is that the WLC2106 seems to be altering the DHCP requests somehow and thus making the ASA5505 not respond to them.  The AP gets an ip address and associates to the WLC if plugged into the 3750, or the ASA directly.  Just not when plugged into the WLC2106 ports.

    I have read quite a few posts with people basically saying you cannot use the ASA as the DHCP server with the WLC because of how the WLC relays the requests.  BUT: (this is important)  There are some documents that say with WLC version 4.2 and above you have the option of turning off dhcp proxy mode to enable bridging mode thus elminating the probem and all DHCP requests get forwarded without modification.  Please see here for suggested solution to this issue:

    *Interoperability issues can exist between a controller with DHCP proxy enabled and devices acting as both a firewall and DHCP server. This is most likely due to the firewall component of the device as firewalls generally do not respond to proxy requests. To work around this issue, disable DHCP proxy on the controller.
    Help please:
    I have tried this but maybe im missing something.  I have tried with proxy enabled and disabled.  Can anyone verify this is supposed to work for me please?  I input "config dhcp proxy disable" and verified proxy is now disabled.  Yet i do not see any responces from my DHCP server to my AP's requests when going through the WLC.  It works fine when plugging the AP into the ASA or 3750.  DHCP server is working.  Is the above suggested work around not a valid solution?  Did i miss something?  Do i need specific software versions on my devices?  Is this a bug in my software versions?
    Any help is greatly appreciated.  Let me know if anyone has questions.  Thanks,

    It keeps seeing the Discover messages but never gets any responce from the ASA.  What does that message mean "dropping REQUEST from STA with invalid mobility state 'Unassociated'" ?  I know the STA is the AP but why is it dropping the request?
    Here is the debug output from the ASA:
    ASA5505lab#  show debug
    debug dhcpd packet enabled at level 128
    debug dhcpd event enabled at level 128

    (IT NEVER SEE'S ANY MESSAGES OR SHOWS ME ANY BLOCKED REQUESTS OR ANYTHING)
    (Now if i move the AP to the PoE ports directly on the ASA5505 you will see the AP get an IP)

    So the ASA5505 is working when the AP is plugged directly into the ASA or a 3750 on the same network.  Only when connected through the WLC i do not see any messages on the ASA.  Is there something else i need setup on the WLC2106 besides turning off dhcp proxy?
    Thanks,

  • Netinstall Image prompt for computer name

    I am wondering how when I am imaging through Netinstall that I can have the image utility prompt for a computer name at image time. Basically I would like to use System Image Utility --> Add a "System Configuration Step" --> prefill the info to join AD but have the person doing the imaging get prompted for the name at image time. How can I achieve this?

    Bump would like to know if anyone else has looked for this functionality.

  • MDT Database - Auto Computer Name Using MAC Address

    I am trying to build a MDT server which will auto name any computer by using the MAC Address of the Network Card, I have read lots of articles and there isn't a definitive answer but I am looking for a simple answer which will work. I have tried all sorts
    of things customising the Customsettings.ini and the unattend.ini and the database.
    These are the settings I am looking at .
    Can anyone please advise me how to get MDT to query the database and output the computer name using one of these variables.
    %OSDComputername%
    %Computername%
    Can you please help.

    Hi Walkermescc,
    Since it is related to SQL database, our help might be limited. I suggest you refer to this article and it might be helpful.
