Migrate server DHCP static leases

Hello

We currently use an old Mac Pro as a DHCP server, use the latest version of server of El Capitan. Now, we want to copy all the static DHCP leases we have implemented (approximately 120 static leases), so that we can put them on another Mac mini, this time takes up half of the leases for a different subnet.

I know that the DHCP leases, temporary positions, are saved in a file that you can delete to erase the leases, but I have not found where static leases are saved. I know that you can change in the Directory Manager application, but I need to export them somehow, so that we can easily migrate. A Time Machine backup is not an option.

Thanks in advance!

See you soon

Apple's DHCP server configuration file is /etc/bootpd.plist

The file you're looking for is/etc/bootptab , but it is also possible to set static IP cards in Open Directory itself in the computerssection. If a card is defined in/etc/bootptab it takes precedence over the setting in the Open Directory.

You can perform the following operations in Terminal.app to get more information

Man bootpd

bootptab man

The file that contains the list of active leases is/var/db/dhcpd_leases

It's a little ironic that Apple uses the name dhcpd_leases dhcpd is a different program from the competing DHCP server to the bootpd use of Apple program. Bootpd Apple is highly personalized on the original version of the open source to add for example the NetBoot support.

  • WLC - server DHCP (Override) and

    Hi guys,.

    A little confused. If I want my wireless clients to a DHCP address on my business DHCP servers, I need to click the Overrides button, for the WLC to act as a relay agent or the docs say that this happens by default?

    Can someone pls confirm, because it is a little confusing. The files help mentioned below also?

    Thx a lot indeed.

    Server DHCP (Override)

    ----------------------

    When the substitution is selected, you can enter the IP address of your DHCP server. It is a required field for some configurations of WLAN. There are three valid configurations:

    -DHCP Server override on a valid DHCP and DHCP address assignment requested server IP address: requires that all WLAN clients obtain an IP address from the DHCP server.

    -DHCP Server override on a valid DHCP and DHCP address unnecessary assignment server IP address: allows all clients WLAN get an IP address from the DHCP server or use a static IP address.

    -DHCP Server OFF Overrides: guests WLAN using the DHCP setting in the Management Interface, not the static address of the Forces.

    Hi Ken,

    Your WLC default is DHCP relay, you do not need to override.

    The WLAN configuration, put you in an interface. If you check this configuration of the interface, you will see that it points to a DHCP server. This is where your WLC relays to wireless clients.

    If you wish to override this setting and to send your customers to a different DHCP server instead, you then click DHCP replace in the WIFI config and enter another IP DHCP address.

  • How to configure server DHCP of VMware Server 2 to play nice on my network?

    I have 8 physical systems running on a network.

    A system running VMware Server 2 on it.

    Server DHCP of Server2 provides virtual machines with IPs on the 192.168.106 network and they all work fine, all virtual machines find each other and physical systems too.

    My wireless router is a DHCP server which provides boxes of physical IPs on the 192.168.2 network and works very well between physical systems.

    The problem occurs when a physical systems trying to access a virtual machine.

    All virtual machines are set to run in NAT mode, I tried no succcess one either bridged mode.

    The VMs system static IPs on the 192.168.2 network also fails miserably as all of my attempts to set masks subnet on all systems.

    I think I need to 'fix' the VMware Server 2 DHCP server, but have not yet find data on this topic, and I'm not sure that if I do this will help.

    Any solution here would be FANTASTIC.

    Past esxi was not really going to do this I feel even if you have not installed - it is really intended for high-end package rather than SATA based servers while sort will work on some.

    Their reason to exceed the NAT is filled? If you want to that virtual machines at all simply appear as regular machines on your existing subnet then packed is the easiest way to go because virtual machines must be able to obtain their IP addresses of your router, as well as physical boxes. DHCP server 2.0 is just for the NAT and host only networking that it manages-for machines virtual NAT, you must configure the port forwarding on the host server 2.0 for all the traffic you want to enter in the virtual machines from the outside since by default, all incoming ports are blocked, appropriately with NAT, see Chapter 11 of the user guide - http://www.vmware.com/pdf/vmserver2.pdf

    So, if you want to go to bridge, we need to understand why this does not work as it should be "out of the box" as long as there is no any firewall host or other security software, for example the clients VPN, which will block traffic. What is the host operating system? Please post ipconfig/all or ifconfig - an output of the host and the guest. How have you configured in bridge network - using the default settings? Virtual machines get an IP address from your router?

  • Only windows server DHCP 2012 does not accept windows 7 Starter ip addresses?

    I want to connect to my PC for wifi, administrators have installed windows server 2012 for the administration of wifi network, they claim that it will not get connected to wifi because I have windows 7 starter edition

    Your question is absurd that there is no distinction between an address IP of Windows 7 Starter.  The DHCP server, they can be configured in different ways, but at its core (no change) he will present IPs to any device that requires correctly and a system functioning and correctly configured Windows 7 Starter would not have a malformed request especially when talking to a Windows Server.

    So as I said before, they do not want you BYOD.  * fault *.

    Windows 7 Starter system in good condition is more than able to get an IP address from any properly configured and nice DHCP server.  I assume that the server is properly configured, just not nice or the workstation is not healthy.

    In other words, you're them, misquoting their incomprehension or they tell you the easiest thing without just said, 'No' or there's something else wrong with your system and that they have no desire to fix it for you, or they should not run such things.

    The simple fact is that Windows 7 Starter is not innate difficulty communicating with a server DHCP R2 open and properly configured windows server 2012 or 2012 in order to get an IP address for itself; now (the server might would be) well assured in several ways but and the Windows 7 Starter system could have all sorts of questions...

  • Migration of DHCP: Old name of the server appears in the console, but OK on server DHCP itself

    Last night, I've migrated our production from 2008 to 2012 R2 DHCP servers. Monitoring the migration pretty well thanks to all of our test environments and PROD so guide. Check the DHCP logs on the new server, everything seems to go OK, but there is a question that we can not understand:

    -In the DHCP console on our desktops, I right click on DHCP for 'add a server... '. »
    -Select the "this authorized DHCP server: ' and I see the new name of the server and the INVESTIGATION period.
    -Now, DHCP in the console, the FORMER name of the server appears under the node.

    I thought enter ADSIedit and change the name of the DHCP server might help, but it didn't.

  • Cisco IOS DHCP Server + classless static routes on DHCP clients

    Hi, I tried to find if it is possible to add the ability for static routes to DHCP clients on the Cisco IOS DHCP configuration mode. I'm looking to add a parameters as defined in RFC 3442, like this one, located on the ISC DHCPd server:

    Global settings:

    121 = integer table 8 code option rfc3442-classless-static-routes;

    ms-classless-static-routes option code 249 = integer table 8;

    And for the subnet declaration:

    option rfc3442-classless-static-routes 24, 192, 168, 30, 192, 168, 10, 1;

    option 24 ms-classless-static-routes, 192, 168, 30, 92, 168, 10, 1;

    Is this possible?

    Thank you!

    Vitor

    Yes, the fun part it is to convert it into a format IOS will accept.  You can try:

    IP dhcp pool 0

    option 121 24.192.168.30 ip 192.168.10.1

    option 249 ip 24.192.168.30 92.168.10.1

    If this does not work, change the "intellectual property" for "hex" and each of your decimal byte converted to hexadecimal.

  • Assign the server a static IP (static local, internet)

    I use the linksys router in my office. WRT54GS V4

    I have T1 line and my ISP is an IP address static 5.

    The DHCP option is enabled in my router. My server is connected to the router.

    If I set up my server with the static IP my ISP provided, my server will not connect to the internet.

    It seems to me that the only way to assign the static IP address to my server's getting a switch/hub

    and connect my router and server to the switch/hub.

    Or disable DHCP and configure networksetting for each n my Office PC. In this case,.

    I need to assign some with local and other IP with static IP address. Can it work?

    If you have any suggestions, let me know.

    Thank you.

    The WRT54GS is a consumer router. It does not support multiple public IP addresses.

    The only way this will work is the way in which you have already found: connect a switch to the conduct of the internet and then connect the server and the internet port of the WRT to the switch. Of course, make sure you configure the firewall on the server very well as it is fully exposed to the internet.

    Otherwise, you will need to get a router which supports multiple public IP, for example the Cisco Small Business series addresses or better.

  • To act as a server DHCP in Windows 7

    Hello

    is it possible to make it act as a DHCP (IP addresses supplier) to a local network in Windows 7? If so, is it still possible even if Internet connection sharing is enabled (and therefore Windows 7 configure static IP addresses)?

    Thank you.

    To the best of my knowledge, the only way to make it act as a DHCP (without 3rd party software) of Windows 7 is to enable Internet connection sharing.  ICS assigns a static IP address to connect to the local network of the host computer and the DHCP server assigns dynamic IP addresses to other computers on the LAN.

  • What type of network configuration... Server DHCP .virtual rent to physical machine...

    Dear all,

    Scenario:

    1. VMware workstation 12 running on a high-end laptop computer.
    2. VMware workstation 12 hosts a domain controller and a domian joined the DHCP role running windows server 2012 R2.
    3. the laptop is connected to an 8 port hub. Hub is connected to 3 physical servers, these 3 servers need a DHCP lease

    Network is "Host Only" what kind of network do on VMWare Workstation and the DHCP server. Please see an article/tutorial if possible

    Thank you for your time, effort and valuable suggestions.

    Hello

    Your DHCP server must be on a bridged network adapter, it does not work with 'host only '.

    Edit: to be clear, I mean the network in your VM DHCP settings, wouldn't "NAT" or 'host-only' but 'bridged '.

    Hi all

    I found the cause of the issue, it is a bad combination of (old) driver NI DAQ and my camera.

    I checked the compatibility of the driver and the device and discovered that I have a different driver from the old series of boards that for the University, we bought and missed me the cd drivers (who disappeared

    I downloaded the new driver NIDAQ1400f1 (or something like that).

    Now it's working.
