DHCP server running Hyper-v comments

• Can not get the comments DHCP server to allocate addresses on VMNet1 Host-only network

  Hi all

  Hoping someone can help with this question, here's my virtual machine configuration basis up to now:

  -Windows 2012 ADDS, DHCP, DNS server

  -Windows XP client

  The two guests use the network to host only VMNet1 and DHCP is disabled through work stations.

  The problem I have is that my Windows XP computer cannot get a 2012 server DHCP address and she comes back with the link-local address of 169.x.  If I configure my Windows XP machine with a static address on the same subnet as the two computers are able to communicate without problem, so I'm not sure where I'm wrong.  Wireshark shows the broadcast DHCPDiscover packet, but nothing is returned.

  These adapters have certain limits they can treat broadcast packets?  Or am I really missing something here?

  Any help is greatly appreciated.

  Thank you!

  Did you check the configuration of your Windows Server 2012 DHCP server? The scope is active? The server is OK?

• WLC 5508 internal DHCP server issues

  Hello

  I'm hoping to get your comments around the issues of dhcp, I faced with two centrally switched Wireless LAN. I have attempted to explain the installation and the problems below and would be grateful if anyone can suggest a solution for the problems I am facing:

  The configuration is the following:

  -J' have a WLC 5508, which has been configured with 4 SSID, of which 2 are the Central authentication and commissioning.
  -J' have a LWAP connected to the WLC in HREAP mode.
  -WLC is configured as a DHCP server for clients that connect to the SSID "Guest." For the rest, I'm on external dhcp server.
  -Only one scope of comments Interface is configured on the WLC.

  Problems:

  1. as far as I know, to WLC serve internal dhcp server, it is mandatory to have the proxy enabled, but the Clients connecting to 'Internet' SSID are

  Unable to get an external dhcp server ip address, if the proxy dhcp is enabled on the WLC. If I disable the proxy, everything works fine.

  2 DHCP does not release the ip addresses assigned to clients, even after that that they are connected.

  3. If a machine that has previously been connected to "Guest" SSID connects to the 'Internet' SSID, he asks the same ip address, he was charged by the WLC assigned under "Guest", it gets the tag with the Vlan configured on the management interface.

• How to configure port forwarding on a dedicated server running CentOS 5.4 to use Ubuntu 9.0.4

  The basic situation that I have is a dedicated server running CentOS 5.4 for the moment I have a virtual machine running Ubuntu 9.0.4. Later, I want to add a virtual computer that is running Windows Server 2003, but right now I focus on the implementation and running Ubuntu.

  The installation of Ubuntu works very well, but I am seriously struggling to get the port forwarding so I can visit the Web sites to be hosted on the Ubuntu VM. As a newbie on Linux, I am confused about the relationship between IPTables and VMWare own port forwarding.

  Here's what I've tried so far.

  My server's IP address is xxx.xxx.xxx.xxx, provider support told me that the subnet mask is 255.255.255.0, gateway address is xxx.xxx.xxx.1 and the network address is xxx.xxx.xxx.0. (These last two surprises me a little, I'd expect to be private rather than public gateway/network address).

  First of all, I tried Bridged Networking, but had no luck contacting the machine other than through the VMware console. I tried it the ping from the host (using ssh in the host), but no joy. also no Inernet access from the VM. I changed the configuration of the DHCP server to static interfaces, using a static address 192.168.1.100 and by assigning to the doors of such xxx.xxx.xxx.1 as advised by the supplier. No real difference, still cannot ping the host prompt, or vice versa and any of the customer's Internet access.

  Then I tried NAT. The host automatically 192.168.132.128 with a 192.168.132.2 gateway IP address now, the client has access to the Internet and when I do a VNC host and open Firefox with 192.168.132.128 I can see the correct hosted Web site but I still can't get in from the outside.

  I mentioned that I am a bit confused about IPtables and VMware port forwarding, what I wanted to say, it is that I'm not sure if IPtable transfer must be set to the IP address of the interface of comments (192.168.132.128 in this case) or the address of the 192.168.132.2 bridge.

  I have the impression that I'm missing something simple here, can someone tell me what it is?

  Find your "/ etc/vmware/vmnet8/nat/nat.conf" file and change:

  Example:

  \[incomingtcp]

  8887 = 192.168.27.128:80

  That would redirect a header of TCP packet entering the port 8887 on the host on port 80 of the guest with the IP 192.168.27.128.

  Ditto for the UPD:

  \[incomingudp]

  6000 = 192.168.27.128:6001

  You can (must) use iptables for firewall purposes but does not redirect traffic at the prompt.

• Keep the IP if the DHCP server is offline now

  We have a customer who wants to be able to manage the IP addresses of all devices with DHCP, but the devices are supposed to keep their IP forever after the DHCP server has been taken offline. Is this a behavior that we can support on a controller of NOR?

  If this is not a configurable behavior an alternative could be to have controlelr auto configure to the last known IP if no such is acquired... but the VI apply network settings doesn't seem to work if done on the controller itself. Is this correct?

  With NEITHER in Norway (thanks), I found a solution which allows us to implement the required behavior.

  The main problem for us once we need to override the default behavior for DHCP was the fact that the RT apply target Network Settings.vi does not work if it is set to target the same controller as it is running. So how to exchange between DHCP and fixed? Well, it turns out that the network settings are also stored in the file of ni - rt.ini. So here's what we do: when the controller starts, we check if it is running in DHCP mode. If this isn't the case, we change this in the file nor - rt.ini and the reset - to see if the DHCP server is operational. If the controller is running in DHCP, we check if the IP address is valid (i.e. outside the local range of link). If it isn't read us the last known IP address and write those set in the file nor - rt.ini and restart.

  An example of the sections of the INI file:

  For DHCP, the section of the nor - rt.ini will look like this:

  [TCP_Stack_Config]

  USE_DHCP = DNS_Address

  Gateway USE_DHCP =

  USE_DHCP = Ip_address

  USE_DHCP = Masque_sous

  For a static IP address:

  [TCP_Stack_Config]

  DNS_Address = 0.0.0.0

  Gateway = 10.0.18.1

  Ip_address = 10.0.18.13

  Masque_sous = 255.255.255.128

  It would be nicer than the network RT target apply Settings.vi would work for auto-reconfiguration, but it saved the day for us at least in this case.

• Requirement of DNS and DHCP Server Essentials 2012 home

  I have a Server Windows Essentials 2012 acting as DNS and DHCP server with a domain name for backups etc on my home network. It's that everything works fine, no errors, no problem. Works well actually, telling me when the children did not install updates or restarted.

  I have two groups of users. My sons step, 10 and 12, which I want to use OpenDNS as a provider external DNS with a policy very, very limited and my wife and me who want to use indications of root or Google DNS or any other DNS provider. Others, specific devices no user (box of the xBox, WII, Satellite, TV, CCTV etc.) can use.

  Before the 2012 server, I had a 2 k 3 server running in a virtual machine for DHCP, alone and put my wife and my devices on static reservations with the just and external DNS provider used OpenDNS as the default scope, DNS. Unfortunately different bits of domain services 2012 don't seem to work unless the server of 2012 is the first DNS server listed on client machines (backups failed. Impossible to find other local computers). Currently, this means that we are all using OpenDNS.

  What I would like is a way to say 2012 to send adult group DNS queries to another DNS provider and leave the rest at default to OpenDNS, while still having them register in the original DNS domain. Any suggestions?

• Can DHCP server with two scopes - I have reservations in doubles in the two staves?

  Hi all

  Not really a guru of DHCP, so be nice :)

  Currently, we run a DHCP service from one of our domain controllers (win 2008R2). The domain controller is the segment of a network (10.10.120.0/24), the computers making DHCP requests are on a separate network (10.10.103.0/22). We use our ip-helper routers setting to say the devices on the network, how to reach the DHCP server. This has worked well for years.  I should also point out it is company policy for PCs/servers have a static IP, so for the PC, we create reservations for each PC. Servers are assigned static mmanually.

  The question is now we have overflowed into a new building and put in a black 1 GB fiber that connects the two buildings. The network in the new building is using a different network (10.10.104.0/24) address. Implementation of a 2nd scope on the DHCP server for this address range went well and once the ip-to support additional parameter has been done on the router the PCs in the new building could fine DHCP to the domain controller in the main building. Everything is good.

  The question is now, we are moving PC between the two buildings, I was wondering if it is ok to keep the existing reserves for the PC in one scope and have a duplicate for her in the new scope assign the new IP address. Of course, the PC cannot be in two places at once and the DHCP console doesn't; "t seem to complain about the same MAC address used in two staves, but I don't really know whether it is advisable or not. Basically, our operations staff become a little miffed at having to remove a single scope of reservations and recreate them in the 2nd scope when the PC to move between buildings.

  So the questions is safe / advisable to do it or not?

  Kind regards

• Client DHCP is unable to get a valid IP address from the DHCP server.

  Client DHCP is unable to get a valid IP address from the DHCP server. I have a home edition of Windows XP attempts to connect to my router wirelessly with wireless or wired connection but I get an error in Event Viewer with the discription DHCP 1007 error message. From what I researched, I discovered that the DHCP service depends on the AFD, TCP/IP and NetBT services. All these services are correctly place and worked very well (even the DHCP service is running without error) but every time I try to release/renew my IP address I receive than DHCP warning in the case where the viewer and I just cannot get a valid IP address of the server (router) I also have one of these verizon wireless G3 usb adapters and it works fine. I also have a good ping back when I try to do a ping localhost (for the closure) I also tried the preinstallation of uninstalled drivers from the adapter/s and nothing works. The only entrees in the registry for DHCP error are also AFD, NetBT and TCP/IP nothing else there, also all the files in the/system32/drivers afd.sys netbt.sys and tcpip.sys in addition to solve the problem, I'll mention that I installed and reinstalled Northon earlier, I do not remember if the problem appears before or after that. I receive also any error or warning in the security log or at least I don't know how to read: P

  Thanks for the information.

  I hope you know that it is risky to connect the laptop to the Internet with no firewall and no antivirus... If this laptop is already connected to the Internet in this State, he is perhaps already infected.

  You said you know the router works because the other computers can connect successfully to it.  You should check the configuration of the router to make sure that it is not configured to limit the number of IP address it supplies, and (b) it is not configured to filter users by MAC address.

  When this laptop is connected by Ethernet, even if he gets the IP address of 169.254.x.y, can you ping the router?  Find the IP address of the router on any computer connected to it by running the ipconfig command in a command prompt window.  The "default gateway" is the IP address of the router.  Run the ping command in the command prompt window as well.

  If the ping is successful, it is possible that you might be able to use an IP address in the correct range for an Ethernet cable (but I doubt that it works for the wireless).

• SG300-10 - DHCP server did not update DNS (bind9) records

  Hello community,

  My SG300 is configured in Mode L3 in my Homelab, and the DHCP server is enabled.

  The switch runs on the Version of the Firmware 1.4.1.3.

  I have configured by a Pool of network VLAN.

  The default router IP address (Option 3), the IP of the DNS (Option 6) and the domain name (Option15) are also configured.

  DHCP works fine without problems.

  Customers get their inclusive information of router, DNS, and domain IP Configuration name.

  As a DNS server, I configured a server bind9 under winded raspbian.

  The bind9 is configured to allow dynamic updates and DNS works as expected.

  Manually using NSUPDATE I can make dynamic updates to bind9 DHCP clients areas.

  But this isn't what I want.

  I want to make the SG300 DHCP server dynamic updates to the DNS zones.

  Would be the Option DHCP 81 (Client FQDN) useful?

  Any idea is welcome. :-)

  Looking forward to hear from you because it drives me crazy.

  Best regards

  Rainer.

  Sorry for the delay in reply Rainer.  I tried to set this up in my lab and became GUI of entry of unexpected results that did not affect the packages at all.  Checked with my contacts and they advised me that it is not supported on this switch option 81.  Given that the client sends to the server on how to update DNS records, the switch does not support this dynamic configuration.

  Referring to the data sheet for the SG300, these are supported options listed:

  DHCP (12, 66, 67, 82, 129 and 150 Options)

  Here is the link to the datasheet.
