DHCP setup

Im DHCP on a slesOES2 box and running zen7 on a sles box. I have set the
server imaging policy so It will only enter into pxe when I hold crl-alt
but when all services are up on the servers the workstations go into pxe
every time(with out key hold). I think the error is in the dhcp.conf.
Exacty how to I need to set the DHCP up to allow PXE. All ive done at the
moment is done a simple subset and added filename and next-server options.

If you have set an imagingpolicy AND there is NO zis-info on the
localharddisk, the machine boots up with PXE. (Ofcourse only when the
parameters in the policy are met.)

DHCP Setup across multiple VLANs on RV325 - DHCP Server only working on VLAN 1

I have multiple VLAN subnets defined on my RV325 - when I try and utilize a DHCP Server on each VLAN, it only seems to be issuing IP Addresses to clients on VLAN ID 1. When I first set this up months ago, I thought I had tested it providing IP Addresses via the other subnets. Now that I am trying to do so, it isn't working "as expected". Example - I am using VLAN 25 as the GuestWireless subnet utilizing a separate 802.11n WAP that is set to Bridge connections to the IP Address of the VLAN interface. Devices are able to connect to the WAP, but end up with a self-assigned IP Address 169.x.x.x address. There has to be an easy fix to this, but I seem to be "stuck" figuring out what it is…pointers/redirects appreciated. Thanks!

Thanks - I've already reviewed that information before I posted. I've been working with DHCP since the mid-90's, so I'm comfortable with the settings/configuration I need to leverage to make this work via other means using various Network-based OSes.
I'm wondering if there are other options in configuring this device that can impact the ability to dynamically serve IP addresses on a VLAN/subnet-by-VLAN/subnet basis.
As I did more testing, I discovered when I reserved an IP Address via the IP & MAC Binding option within the DHCP Settings, those devices would receive their static reservations and work as expected, so the problem seems to be leveraging the DHCP Pool for devices connecting to VLANs other that VLAN 1.
Any ideas as to why the DHCP Pool's are "non-functioning" for the other VLANs is greatly appreciated...

DHCP setup on Time Capsule

Hi
I need to connect a Mitel IP Phone to a Time Capsule that is currently setup on Bridge Mode and working well. The TC gets its internet connection from a ADSL modem/router.
When I switch the TC to DHCP/NAT mode I get a Double NAT error.
When I switch to DHCP Only I get an Invalid Value error stating "Sharing a range of IP addresses using DHCP Only requires manually configuring your WAN IP address. If your ISP gives you a range of static IP addresses, you should manually configure your base station with the first IP address and distribute the rest via DHCP."
Any ideas how to resolve?

The TC itself has an IP address even in bridge though.. which is derived from the main router.. similarly any other device you plug into the TC must get an IP from the main router.. the fact that it is bridged is irrelevant..
Can you please completely remove the TC and plug the ip phone directly into the EOP adapter. Does it get an IP address?? If not then simply changing the mode of operation of the TC still won't work. If it does work it must work with the TC in place just as well as without it.
TP Link TD-W8960N ADSL2+ which is plugged into a Huawei Echo Life HG612 VDSL2
This is really not good.
The 8960N is hardly a fit router. Why do you need it setup this way. If the HG612 is a pure modem.. then I recommend you swap the TC to act as the main router.
Connect the 8960N in wan bypass at the other end of the power line connectors and simply plug the IP phone into that.
At least buy a real router to replace the 8960N which is an adsl modem router which barely functions as a WAN router.

DHCP setup help on AIR-WLC-2112 with LAP1042N

I am new to wireless. I would like to statically assign ip addresses for my controller(AIR_WLC-2112) and my access point (LAP1042N). I would then like the controller to distribute dhcp addresses for users. What is the best way in doing this?

Hi Mark,
You can certainly setup your network for 2 VLANs for different wireless networks. You will only need to setup the switchports to the WLC as trunks. In other words, the APs will simply reside in the vlan you define (access switchports) and they will tunnel all traffic back to the controller, regardless of client vlan. The WLC will then determine which vlan the traffic needs to go on.
You have 2 ways of setting your AP IP addresses as static -- you can statically assign them through the console during initial installation:
capwap ap ip address
capwap ap ip default-gateway
capwap ap controller ip
Or, you can simply let the APs start by using DHCP, and auto discovery of the WLCs via DNS lookup of "cisco-capwap-controller", or DHCP option 43. Once they join the controller you can assign them static addresses in the WLC AP settings.
Now, onto the last question regarding your WAN sites. We do have options for you there as well -- the feature we're looking at would be H-REAP. Traditionally the APs tunnel all wireless traffic back to the controller. However, in H-REAP mode, you can specify the APs to put traffic on the network right at the local switch, so it wouldn't have to get tunneled across your WAN (depending on WAN bandwidth). You still configure the AP and manage it centrally. For more information on this feature, please check out the H-REAP deployment guide:

Window 2008 R2 DHCP setup for /21 subnets

I have a 2008 r2 domain server that I am setting up separate client DHCP scopes. One for regular wireless network and one for the guest network. I followed the same process to create both but they both created differently when viewed in the DHCP
mgmt interface. The .40 is working, the clients grab the next available IP and they are off. The .50 is not working correctly or the same way. See detail below.
I created a Scope for the wireless network clients 10.100.40.0 /21 Range 10.100.40.1-47.254 subnet mask 255.255.248.0 The
scope created as a super scope and added scopes .40 .41 .42 .43 .44 .45 .46 .47 (all as separate scopes under the super scope) for distribution which is accurate according to the subnet calculator. I excluded 40.1-10. It works! clients fill up
.40 and move to .41 etc. Statistics total scopes 8, total addresses 2023, in use 874, available 1149.
I created a scope for the guest wireless network clients 10.100.50.0 /21 same way! Range 10.100.48.1-55.254 (according to the subnet calculator)
subnet mask 255.255.248.0 The scope created as a regular scope 10.100.48.0 /21 starting address assigned is in the 48 subnet. I excluded 10.100.50.1-10. Statistics total scopes listed none ( no line), total addresses 2036, in use 262, available
1774.
I would prefer they both be set up the same way and functioning. As I said earlier .40 is working great! but .50 seems to have some .48 clients, 3 49 clients and a small group for 50 starting from the exclusion. I am not sure it is working
correctly ... I have had several people tell me that they are not able to grab an IP on the guest network. I have tried to recreate several time with out any different results.
Anyone have any ideas why .50 is different and what I could do to fix this? Thanks! chabo
chabt

Hi chabt,
Based on your description, I suppose that when you use
New Scope Wizard to create the super scope, you choose 24 in the
Length edit of Configuration settings that propagate to DHCP Client, that is to say, the subnet mask is 255.255.255.0. Then the New Scope Wizard will prompt you create a superscope because the address range you specified is
too large for a single scope. If the subnet mask is 255.255.248.0, it won’t prompt you create a superscope.
About the Statistics displaying, please try to restart DHCP server to see if it can display normally.
About the problem that several users couldn’t obtain an IP address, because other users can get IP addresses, please check if they match the policies on your guest network.
Also, please check the DHCP logs to see if the DHCP server logged any related logs. Such as, you could find if the lease was denied, or if the DHCP server received the DHCP request or other useful information.
The dhcp logs are stored in %windir%\System32\dhcp. Please ensure that the DHCP server enabled audit logging.
To enable DHCP audit logging, in the DHCP console, right click
IPv4, click Properties, in the General tab, check “Enable DHCP audit logging” checkbox.
For more details about DHCP audit logging, please refer to the article below,

SG500X DHCP setup - option 242

Good day
I'm trying to configure DHCP option 242 on a "Cisco" SG500x switch for Avaya phones that will be connecting to the switch
I have learnt (the hard way) that the SG500X "IOS" is different to what we are used to ...
Option 242 works perfectly on a Cisco 887VAG, but I can't get it configured on this switch
At this stage I don't have access to the Graphical Interface, switch is at a remote site, and only connection is console.
So here is what I have

How can we change our config to include both servers so we don't have to modify it when one server is down?The easiest way is to specify both server addresses in the AltAuth option:
option NewT.AltAuth 192.168.92.197, 192.168.92.198;
Another approach would be to move away from specifying server addresses in DHCP and do it by using DNS instead. Apparently this approach hasn't made it into the official SRSS docs yet but you can read about it in the ThinkThin blog at http://blogs.sun.com/ThinkThin/entry/sun_ray_provisioning .

LRT224 Load Balance "dumb" DHCP router setup... HELP!

Hi
I'm trying to set up a LRT224 with two ADSL modems connected to one network with load balancing.
I'm not going to use vlan or vpn at all.
All I need it to do is be a "dumb" router that combines the speed of both Internet connections.
Working mode is set to Router
LAN 192.168.0.1/255.255.255.0 (I changed the LAN ip range)
WAN 1 and 2 gets IP, default gateway and DNS trough DHCP from the modems.
Wan 1: IP 192.168.1.65 Gateway 192.168.1.1 DNS 192.168.1.1
Wan 2: IP 192.168.2.38 Gateway 192.168.2.1 DNS 192.168.2.1
DHCP setup:
Device IP: 192.168.0.1
Subnet: 255.255.255.0
DHCP Server
Range 192.168.0.50/254
DNS: Use DNS from ISP
Dual Wan:
Load Balance
I'm no IT expert at but I have set up a few routers before that was close to "plug and play"
My problem is that connected computers indicate that they are connected to Internet, but I'm not able to access any websites.
When trying to use windows troubleshooter it indicates that there is a DNS problem.
I'm not even able to connect to the modems.
Installed latest firmware and done a fabric restore.
Network is built as follows (still working as I'm not running anything trough the lrt224 before I can get it to work)
ADSL Modem with built in DHCP and Switch --> Switch --> Ubiquiti Unifi AP --> User
Some of the AP's is connected via Ubiquiti NanoStation (wireless bridge between 4 houses, works great)
Any idea how to get this to work or do I have the wrong router?

I recommend:
Modem1 (192.168.1.1)=> LRT WAN1 (192.168.1.254)
Modem2 (10.10.10.1) => LRT WAN2 (10.10.10.254)
LRT WAN1 SN (255.255.255.0)
LRT WAN2 SN (255.255.255.0)
LRT WAN1 GW (192.168.1.1)
LRT WAN2 GW (10.10.10.1)
LRT WAN1 DNS (192.168.1.1)
LRT WAN2 DNS (10.10.10.1)
System Management => Load Balance
LRT DHCP Device IP (192.168.200.1)
LRT LAN => Switch => Ubiquiti Unifi AP => User
Nothing other than the LRT's connected to the modems.
If the modems DHCP is set to 192.168.1.x and 10.10.10.x subnet 255.255.255.0 then DHCP setting will work on the LRT WANs.
Please remember to Kudo those that help you.

Configure DHCP Server options for Internet Sharing?

Good morning, all.
I have a Sprint (Sierra 595U) AirCard internet connection, which I'm sharing over my AirPort (using OS X's built-in Internet Sharing) to several Windows clients in my office. I see that when Sharing is enabled, en1 takes on the address 10.0.2.1 by default, as well as the role of default gateway/router and DHCP server for the Windows clients.
My question is: Can I configure the IP addresses and DHCP options for Internet Sharing to another address/mask scheme?
Just like I changed my home wireless network away from the default 192.168.1.0/24 for security reasons, I'd like to do the same here.
Thanks and Regards,
BrooklynWalker

Yes, of course security paranoia can be cultured. like yogurt

This might help:

DHCP does not load as a service from the Server Admin

Dear friends,
I have faced the following problem.
The task is to do internet sharing among other services on mac mini server.
Started with the clean install of OS X Lion, upgraded it to Server and then installed all updates.
USB Ethernet (en2) is looking into ISP with static IP, Ethernet (en0) is LAN.
Since I need specific address scope for the LAN I have actived DHCP from the Server admin and configured it to provide
192.168.8.11 to 192.168.8.200 as an adress scope, mask 255.255.0.0 on the interface en0.
Everything was working just fine for a couple of minutes and the LAN clients got their IP addresses from the DHCP scope. In a very short time Server Admin popped up and error message:
Try to refresh the view (aserver.local./Server). (kReceivedUnknownError)
Niether grey nor green bubble apears near the DHCP on the service list.
I keep recieving this error for all other services until I manage to disable dhcp on the services tab of server settings. After all I cant make it run again. I tried to restart dhcp from the terminal but it does not help. "sudo serveradmin fullstatus dhcp shows nothing".
Do you have any ideas how to make it work?

So you're not using NAT between the two? Even though you're using 255.255.0.0 so both network can talk (basically you have a class B network setup using Class C ip addresses), your network masks for each should be something like 255.255.255.xxx depending on how many subnets you need. NAT or Network Address Translation should be running and that will provide the interconnectivity between the two.
Your DHCP server should be set up only with 255.255.255.0 for the DHCP service since you are only serving IP addresses to the one subnet 192.168.8.x. Your starting address in DHCP setup is 192.168.8.11 ending address 192.168.8.200 and the netmask should be 255.255.255.0.

DHCP start at x.x.x.45 to x.x.x.90 , witch subnetmask?

Hi, I can't find the answer.
Here is my situation,
Linksys- router as Gateway to the internet. IP-192.168.2.254
OSX-Server provinding Mail, web DHCP and so on. IP-192.168.2.11
Some Machines with static IP from 192.168.2.12 to 192.168.2.40
And some machines with static IP from 192.168.2.100 to 192.168.2.110
I want the DHCP to serve numbers between 192.168.2.45 to 192.168.2.90
So that the static IP's are out of the range.
My problem is that DHCP is not working properly.
These are the errors;
Nov 13 13:57:32 eps-amsterdam bootpd[1191]: can't open /etc/bootptab
Nov 13 13:57:32 eps-amsterdam bootpd[1191]: server name eps-amsterdam.eps

Nov 13 13:57:32 eps-amsterdam bootpd[1191]: subnets: Failed to convert 'nbover_tcpip_nameserver': Invalid IP address
I Think it must be the subnetmask but I don't know witch number to use.
In the DHCP setup teh settings are these;
Starting IP 192.168.2.12
Ending IP 192.168.2.90
Subnet Mask 255.255.255.0
Router 192.168.2.254
What am I doing wrong?

"Hmm... Do you have DNS entries for "server-leopard" ?"
No I don't have an entrie for that.

Multiple Leopard Servers - DNS Setup

Hi guys,
Just wandering what I need to do when setting up more than one server on the network with my DNS settings.
I already have a leopard server box, running advanced with DNS setup and working correctly. How do I setup the second server?
Do I create a machine record on the original server, as if the new server is just another network device, and not turn on dns on the new server?
Thanks,
Nige

"If you like you can add a NS record for the new machine/DNS name, set the new machine up as a secondary/slave DNS and allow for zone transfers in the first primary/master one. "
hmm, I think I follow.
"The second one should use the same forwarders as the first one (both machines should only use itself as the DNS in Network prefpane) and also the LAN reverse zone (*.in-addr.arpa.) should be zone transfered to the secondary DNS."
Are there instructions on setting up a secondary DNS?
"In DHCP setup also add the second machine/DNS IP so clients can use either/both."
I'm not running DHCP on the server, so I'm not sure what I can do here.
I guess I'll need to do a similar thing with directory as a well, so that both servers have the same users and groups.

Oracle on DHCP enabled servers

Hello:
I installed Oracle on my home machine which is DHCP enabled.
The installation said that I have to add Microsoft Loopback adapter. I did it and the installation was successful.
But when I rebooted by machine, I could no longer connect to the internet. When I deleted the loopback adapter, I could. But Oracle DB Console does not get started.
When I added the loopback adapter, it started again but I lost my internet connection!
Can somebody shed light on how I can solve the problem?
Thanks.

HI . I need some assistance. How do I install DHCP? Can you give me the steps how you did this. I am very new to ORACLE and the DHCP setup. I will appreciate it. I am in class and trying to get my trial oracle 10g r2 up and running. I have the software installed now but the DHCP still have a warning.
Thank youWhy are you hijacking a thread that is nearly 4 years old? You should post you own question as its own thread.
But since we're here ....
You don't install dhcp. It is a method whereby a computer gets its IP address assigned by some other device on the the network. And said IP address is not guaranteed to be the same every time the computer starts. That is why Oracle (actually any sever process) does not like to run on dhcp assigned addresses. Trying to reach said server from a client process would be like hitting a moving target. That is why the installation instruction for oracle (you did actually read them, right?) instruct you to install the loopback adapter if you are running your pc under dhcp. This will give your pc a second, fixed, network address that is accessable only by other processes running on the same machine.

DHCP Server - Different Range for Wired and Wireless Network

We have DHCP setup on Windows Server 2012r2 and the range given to us by the main HQ is 10.65.112.1-10.65.112.254 (there are several exclusions under this range)
Now since the range gets exhausted quickly, they provided another one 10.65.122.1-10.65.122.254.
What our branch would love to do is to dedicate the first range for Wired Computers and the other range for Wireless Devices (Phone,Tablets, Mobiles)
Right now we have 2 different scopes setup in DHCP, the second one is disabled. In our network we have 6 access points and also have a CISCO SG300-52 Managed Switch. It has an inbuilt DHCP Server and also has the function for DHCP Relay. But we are not actually using any of its functionality as of now.
So my question is how to have 2 separate ranges for wired and wireless network. People have mentioned vlans but I have no clue on how to get that done.
Is there a simpler way avoding V-LANS or if not, would love to get step by step procedure on how to go about this. Any help will be much appreciated
Regards,
Sheldon

Hi Sheldon, please read this post

You will need some modifications though. Steps 1-6 is very relevant. On step 6, you need to pay particular close attention to the "default router". If the SX300 handles your intervlan routing then the default router needs to be the IP of your VLAN. If you have a different device to handle VLAN routing then the default router needs to be that IP address.
