IP Address and DHCP Server

anyone know if there is a way to turn off the dhcp server on the airport. This seems like a basic task to do but i just can't seem to find it. It should be there as even a 5 year old wired linksys router has this option. Along with that, is there any way to change the local ip address of the router to anything but the default .1 at the end of the ip address. This is because I have it routing on 192.168.2.... I also have a ubuntu server up and running that is manning the ip addresses, therefore it is not possible to have both of the the servers up and running at the time. That is why I would prefer the airport to go on 192.168.2.2 and the server be on 192.168.2.1.
Is any of this possible?

Hello ecbtln. Welcome to the Apple Discussions!

Yes, the only way to disable the DHCP service is to set Connection Sharing (on the AirPort Utility's Internet tab) to "Off (Bridge Mode)."
Along with that, is there any way to change the local ip address of the router to anything but the default .1 at the end of the ip address.
Sorry, but no.
also have a ubuntu server up and running that is manning the ip addresses, therefore it is not possible to have both of the the servers up and running at the time.
Reconfiguring the base station as a bridge will "pass thru" the DHCP service from your Ubuntu server.

I tried to track issue with microsoft network monitor I'm attaching the capture file also please help me to sort out this issue
capture report https://onedrive.live.com/redir?resid=AFE3D0245A92F6F8%21183

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

AVAYA IP Phones unable to get an IP address from DHCP server.

I installed new SRW208P switch and I mada an uplink connection with SRW 2024 switch (using GE port).
when I am trying to connect AVAYA IP Phone to the SRW208P port, the set trying to get an IP address from the DHCP server and failed to get it.
some times after 10 minutes, it get the IP address, but all the machines (PCs) connected to the same switch (SRW208P) hange.
Note: the PCs an IP Phones are connected with separate UTP cables to the access switch.
Is there any suggestions to solve this issue, please.

TSIG Key and ip address in DHCP Server Setting

Hi all,
i would like to display the ip address leases in the java dns/dhcp management console. Tried to follow the description in chapter 7.2.14 (oes2 dns/dhcp documentation) and created the TSIG key. But after that i'm unable to add it to the server object because the 'omapi-key' attribute is missing...
The seccond issue is, that i cannod add the dhcp servers ip address to the dhcp server configuration using the java console or imanager...
Any ideas?
Environment is oes2/sp3
David

David,
Check out TID 7006450, Viewing Dynamic Leases Under the DNS/DHCP Mgt Console from OES2.
Hope it helps.

Phones not getting IP address via DHCP server on same VLAN

Hello....we have a new series of Cisco SF-200s and one new Cisco SF-300. All switches are operating in layer 2 mode currently. Let's say for all intents and purposes, all ports are in VLAN1....pretty much default setup. There is a fiber backbone between uplink ports...and it is working correctly it appears.
There is a DHCP server allocating addresses 192.168.0.60 thru 192.168.0.79. Subnet mask is 255.255.255.0.
PCs and laptops successfully receive an IP address and can access things.....such as surfing the internet. Tested that from multiple switches....all seems to work just fine.
However, it seems that some newly purchased phones (Digium models) simply will not acquire an IP address like the PCs and laptops do.
Pretty broad question....but just wondering.
Thanks!

Hi Greg,
Might be interesting to goto the following sections of the GUI disable the discovery protocols;
1. Administration>Discovery -LLDP >properties
2. Administration>Discovery -CDP >Management interface
3 Smartports >Properties > Admministrative Auto Smartports is disabled.
the switches are real smart and may pre-empt what you are trying to achieve.

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.

SAP NetWeaver 04s SP7 installation and DHCP server

Hi All,
I am installing SAP NetWeaver on a machine which I use at work. I am little scared whether this installation might harm my computer or the local corporate network. This machine is connected to the local network (uses DHCP) to get the IP address.
Are there any precautions which I need to take before I start practicing on this platform ?
I read this below point in the installation instructions...
=========================================================
If no DHCP server is available on your network (which dynamically determines the IP address) or your computer is not connected to any network, you need to install the virtual interface adapter MS Loopback Adapter. This is described in detail within the contents of the download package.
=========================================================
Now as my computer is using DHCP (unknown location), if I install SAP NetWeaver 04s SP7, do I need to disconnect my comp from the Network and then install the MS loopback adapter ? or Its ok to ignore the DHCP option as my comp is already using DHCP ?
Thanks and Best Regards
Ayub.

Hi Ayub,
U dont need to disconnect ur computer from network. Just install a microsoft loopback adapter and assign it a static ip, and assign that ip and hostname on windows\etc\hosts file. it will installs on loopback adapter and ur local network connection will be as it is.
hope it will help u.

Running vrf-lite and dhcp server see 0.0.0.0 as giaddr

Im running vrf-lite and our dhcp server see only 0.0.0.0. Im able to ping vlan10, and see the dhcp request. Running on a 2811. I have limited access to device. Do I need to turn on Dhcp-relay? Verifing ip forward-protocol. Do i need to add " vrf WISP to my helper-address? The interface it sends Dhcp request is also within the vrf. The dhcp scope is part of Vlan10 subnet
int vlan 10
ip vrf forward WISP
ip add x.x.x.x s.s.s.192
ip helper-address x.x.x.x

Yes and no. It uses another interface thats within the same vrf Wisp. On the other end of the vrf it is forwarded to our global dhcp server. in bold is where the unicast packet are going using the defaultroute
int fast0/0.1
encap dot1q 1
ip vrf forwarding WISP
ip add 172.16.6.2 255.255.255.252
int vlan 10
ip vrf forward WISP
ip add 66.223.195.129 255.255.255.192
ip helper-address 208.138.129.49
ip route vrf WISP 0.0.0.0 0.0.0.0 172.16.6.1

Flexconnect - Local Switching and DHCP Server Location

Hello Friends, It is again a conceptual question.
In Flex-connect Local Switching mode if the Client has to be get the IP address using DHCP, the DHCP server has to be local to the remote site and not centralized location. Though i know, Local switching means that the client traffic is bridged to the local network directly by the AP on the locally connected switch and does not pass through the controller, what does it mean to DHCP server location.
For example, If I have 2 different WLANs (VLAN 2 and VLAN 3) configured Local Switching and its corresponding VLAN SVIs are configured in the Local L3 Switch and if the DHCP server is centrally located with the scopes for VLAN 2 and VLAN 3, will it have troubles?
I see in my infrastructure we are working in that way [Local switching with centralized server]
Thanks in advance

It would be good to have DHCP server at local site.

I want to reserve a static IP address on my Airport extreme. What is the difference between reserving by MAC Address and DHCP Client ID?

I want to understand the differences in the way you can reserve a static address for a device on the network. I had previously set the device itself to an address and then reserved it with DHCP Client ID, which I thought was just the devices static addresss. I'm not sure if this was in fact correct or just happend to work. I know what a MAC address is, but I'm not really sure what the DHCP Client ID is. So it would be great if someone could clarify it, and the difference between reserving address by MAC Address or DHCP Client ID.

A MAC address is a unique identification consisting of letters and numbers in a form that looks like this:
xx:xx:xx:xx:xx:xx
Every network device has a MAC address, which can be found on a label on the bottom or back of the device. Apple calls this the Ethernet ID.
A DHCP Client ID is an optional name that you can assign to a device. For example, on your Mac....
Open System Preferences (gear icon on the dock)
Open Network
Click on Ethernet
Click Advanced at the lower right
You may be able to edit the DHCP Client ID here....for example.....you could enter MJ500's MacBook in the space provided. That would be the Client ID of your Mac.

How to configure Oracle Linux 6.5 to request ip address from dhcp server

I have installed Oracle Linux 6.5 (minimal installation) on a virtual machine created on VMware vSphere 5.5. I have tried to configure dhcp during the installation by editing IPv4 Settings of System eth0 to use Automatic (DHCP) but somehow it does not work.
Then I changed the ifcfg-eth0 to use static ip address and that works.
Here is the content of /etc/sysconfig/network:
NETWORKING=yes
HOSTNAME=TESTOL
Here is the content of /etc/sysconfig/network-scripts/ifcfg-eth0 using static ip address:
DEVICE=eth0
TYPE=Ethernet
UUID=xxxxxxxx.xxxx-xxxx-xxxxxxxxxxxx
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
HWADDR=xx:xx:xx:xx:xx:xx
IPADDR:##.##.###.###
PREFIX=24
GATEWAY=##.##.###.###
DNS1=##.##.###.###
DOMAIN:test.com
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"
Based on my understanding, I should able to use dhcp by changing ifcfg-eth0 (I commented the parameters not needed for dhcp by adding #) but I have tried the following ifcfg-eth0 and it does not work:
DEVICE=eth0
TYPE=Ethernet
UUID=xxxxxxxx.xxxx-xxxx-xxxxxxxxxxxx
ONBOOT=yes
NM_CONTROLLED=yes
#BOOTPROTO=no
BOOTPROTO=dhcp
HWADDR=xx:xx:xx:xx:xx:xx
#IPADDR:##.##.###.###
#PREFIX=24
#GATEWAY=##.##.###.###
DNS1=##.##.###.###
#DOMAIN:test.com
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NAME="System eth0"
I have also tried to add GATEWAY=##.##.###.### to /etc/sysconfig/network but that does not help.
I have checked that dhclient package is installed by using rpm -qa dhclient.
I'm new to Linux.
Thanks for any help

If this is your first experience with Oracle Linux, I recommend you perform a default installation instead of going minimal, which is just going to make things more difficult for no good reason. Enterprise Linux is not MS Windows and the difference between default and minimal installations do not compare.
You also do not want to use the rpm utility to install any software and use yum instead. The yum utility is standard. Rpm does not resolve software dependencies.
Your ifcfg-eth0 script is missing the line that specifies to use DHCP:
BOOTPROTO=dhcp
You can also use the network configuration utility, even in text mode, by typing the following at the command prompt of root:
system-config-network
If the above utility is not installed:
yum install system-config-network-tui
You will have to configure an appropriate yum repository file. The process is explained in the Oracle Linux release notes:
https://oss.oracle.com/el6/docs/RELEASE-NOTES-U5-en.html
See 3.2.3. About Oracle Linux Installation Media
Then insert the DVD or attach the DVD iso image to your virtual machine and mount it as following:
mkdir -p /media/ISOimage
mount /dev/cdrom /media/ISOimage
The path "/media/ISOimage" should be the same as you specified in the yum repository file.
After that you can use the yum utility to list or install software.

IPad wont get IP address from DHCP Server

I have an enterprise WPA2 PEAP MSCHAPv2 wireless network. It allows access via 802.1x authentication using Radius (MS IAS Server) with certificates. I can join the network, enter credentials (that I can see work) and get the certificate. The problem is that I don't get an IP address. I get a 169. APIPA address. I tried to use a static IP address and that doesn't work either. I have connected various laptops, iPhones even a Dell Streak to this wireless network without issue. My iPad won't get an IP at all. There are plenty of addresses in the pool.
The setup is a 3COM WX3008 wireless LAN controller and 9552 access points.
Any ideas? I went through the articles on wireless settings and none of them help at all. I guess my next step is to wipe the iPad.
Like I said... EVERYTHING else works, every other device we try is surfing just not the iPad.

I see what you are trying to say but in this case its just not true. There is a problem with the iPad. Moving away from the most secure wireless technology or changing my "router" isn't a reasonable solution. We are using a current production model enterprise wireless LAN controller with lightweight access points. Its running its latest code. Its not the Free After Rebate model from the local B&M.
Again, when everything BUT the iPad works (iPod/iPhone/laptops of varying OS & vendor are all good) its not the routers fault. While downgrading my network may work it is not a reasonable solution to a problem with only the iPad.
Of course I don't like hearing it. I am here to hopefully find someone else with the same issue or get some tips that lead to a solution so the next google searcher will land on a solution.

IPad suddenly doesn't receive IP-address from DHCP-server

I have a wireless network running 802.11x consisting of an SMC-router/AP. The network has an additional access point - actually a homeplug device (Netgear) which however is connected to the router directly by wire (ethernet cable).
The problem is that my iPad 2 sometimes drops the assigned IP-address and won't receive a new one from the router.
This is how it looks seen from the router's admin interface:
When software-resetting the router, it delegates new IP-addresses to the various DHCP clients and also to the ipad. However, the ipad never receives these settings.
Strangely, when I renew the lease on my iPhone 4, that device does receive new settings from the router.
And even more strange: When I share the iPhone's network, the iPad will connect through that connection right away.
So far, the only way to solve this has been to remove power from the router and reboot it while keeping the iPad in the vicinity of the router's own AP instead of the other AP.
The problem isn't persistent but it reappears from time to time with no apparent reason.
Any suggestions on what could be wrong here?

Crlarsen-
One thing you did not mention, was resetting the iPad's network. Go to Settings-General-Reset-Reset Network Settings. You will need to reconnect the iPad to WiFi.
