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.

DHCP Server for AIR-LAP521

Hi,
i have a test setup with a WLC-526, a few AIR-LAP521 and a 2621 with an ios 12.2.31 . I' not abel to associate the 521 to the WLC. I have configured an DHCP server on the Router with option 43 ascii "ap-managent-address" of the WLC. The DHCP server packet debug looks like :
DHCPD: DHCPDISCOVER from
DHCPD: Sending DHCPOFFER to
DHCPD: broadcasting BOOTREPLY to
DHCPD: DHCPDREQUEST received
DHCPD: Sending DHCPACK to
DHCPD: broadcasting BOOTREPLY to
and about 20 sec later :
DHCPD: DHCDPRELEASE message received
Has someone an idea how to configure a dhcp server for a 521 correctly. ?
Thankx

Hi Carl
It's the real address. And if you are using secondary IP's it's still the primary real address.
Simon

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.

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.

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:
http://www.cisco.com/en/US/products/ps6366/products_tech_note09186a0080af5d13.shtml#topic2
*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,
Kyle

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,

You can probably find it in the DHCP log if logging is enabled.

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?

How to setup IOS DHCP server for redundancy?

Hi
The customer has 2 core (cat6). Plan to enable DHCP service on them for IP phones.

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,

but from what I just read, changing away from the default net & mask might be putzy.Some other discussions for you:

or you might see something here that helps.
Sorry not to be more specific. Hard to tell if you already googled for yourself.
I'll let someone smarter than I am take a look for you, here.

DHCP Server Daemon for Aironet

Hi,
does Cisco Aironet acts as a DHCP server for the wireless client?
Thanks.

Nope...Cisco Access Points can't work as a DHCP server for the wireless clients..Tejal

Can I use ASA to be a DHCP Server use in WLC wireless Client

I want to use ASA to be a DHCP Server for Wireless Client not it can't.
I check the debug log in WLC, I confirm the WLC have send the request to ASA.
In the ASA, it don't have any hits in the rule when the WLC send the DHCP relay request.
I have try don't use dhcp relay in WLC but don't success. Anybody have the same case with me? And Is the ASA can't support DHCP relay agent to request to get the IP Addr.
P.S. In the Network Design limitation so I can't use WLC to be DHCP Server.
Equipment:
ASA5510
WLC4402
How can I fix it.
Thank you very much

The issue is that the ASA doesn't accept DHCP requests from a relay agent, only broadcast DHCP requests. In the 4.2 version for the controllers there is now an option so you can change the way the controller forwards DHCP requests so that it is sent as a broadcast and not from a relay agent.

The issue is that your machine is not being assigned an IP address / was unable to reach the DHCP server to receive one. The 169.254.x.x IP your machine is showing isn't assigned from DHCP, it's assigned by the local machine and is referred to as an APIPA
address.
So something is preventing your machine from reaching your DHCP server, which could one of a number of things. In the first instance I'd suggest having a look at
http://epan36.blogspot.co.uk/2012/09/eventid-1001-dhcp-your-computer-was-not.html which lists several of things that could cause this error and things you can try in order to resolve it.
If none of those work, can you confirm whether you have any other machines connecting via the same method on the network, which might indicate whether this is an issue at the machine end or somewhere between the machine and DHCP server?

AP gets always a new IP address from DHCP server

Hello,
When an access points doesn't find a controller it gets always a new IP address from DHCP server.
Does anyone know, why?
thanks

Hi,
From what I know this is to do with DHCP option 60 and 43.Normally when APs request for IP address, DHCP Server also returns the management IP Address of WLC if the VCI matches.
If the VCI sent by the AP does not match with the one configured under DHCP for that particulart AP type, the DHCP will never return the WLC IP and hence AP can not find the controller.And the AP keeps sending DHCP Req and sometimes end up getting two IP addresses!
So may be you can check VCI on DHCP server for that AP model.
Let me know.
Cheers
