Stop proxy dhcp

I have just installed zcm10 on a windows server and wish to disable the proxy dhcp on the Netware6.5 server running ZEN Suite 7. How is this done?
Thanks
Dave.

That worked
Thanks alot.

E1200 stops serving DHCP all of a Sudden (affects both wireless and wired)

Greetings All,
I have a 2 year E1200 router that has given me very good service uptil now. Now, it appears to suddenly stop serving DHCP at least once daily. This results in a situation where all my devices (3 over wifi, 2 directly wired) suddenly all cannot talk over the local LAN or reach the Internet (WAN).
This issue started about a week ago when the build I live in had an issue with its network - they won't give a full explanation of what the exact issue was but somehow some media gateways were requesting MAC addresses (ARP?) from every single device in the building constantly. Since then, my E1200 gets into a funk daily, typically at night when it is idle, though I have seen it get into this condition during the day when I am actively connected to a VPN at work.
My network consists of 3-4 wireless devices, 2 wired devices connecting to the E1200 (wpa2-psk) and the E1200 is connected to a Digital-to-Analog GW that converts fiber input to 100Mb Ethernet. I have the latest firmware on it.
I realize this is very scant information to begin a hypothesis so any suggestions on whether this is a know problem and if so, how to rectify it? If it is not known, I'm all ears on how to debug it.
So far, my work around has been to reboot the E1200 and that clears up the issue but clearly that is not a good long term solution.
Thanks,
H

Hi,
If you have time, you can try to perform a hardware reset on your E1200 then reconfigure it back manually. Since you are running on the latest firmware, there's no need to reflash that. You might still have the same issue if there's really a problem from your gateway.
If everyone needs to believe in something, I believe I'll have another beer..

PXE-E51: No DHCP or Proxy DHCP offers were received

Ok so I'm new to this and decided hey lets have a go.
I got it all working great and then all of a sudden after a server reboot I got this:
PXE-E51: No DHCP or Proxy DHCP offers were received
My DHCP,DNS,AD and WDS are all on the same box, I spent hours trawling the net and didn't find the answer to my problem but have stumbled across it although about 10hours wasted for a really simple solution
The cause: seems my WDS side is loading before my DHCP is having chance to establish hense WDS can not talk to DHCP to get the pxe connection going.
What did I find:
If i close the GUI for WDS and open the GUI for DHCP, find my server int he tree and right click then select restart. wait for this to complete (that's the important part)
Once the above is done open my GUI for WDS and again find the relevant point in the tree, right click and restart
Low and behold my connected laptop is now able to connect to the WDS.
I posted this in hope that it will save someone else a heck of a lot of time (can't promise your issue is the same as mine as there are so many different possibilities.)

Because PXE and DHCP use the same protocol and listen on the same ports, having them on the same box is unwise. There is a work-around but the better option is to put the two services on different systems. The work-around involves configuring the
WDS server to use alternate ports as briefly discussed here:

WAP551 stops passing DHCP

Hello
I have 4 WAP551s at one of our sites, and I have discovered a problem whereby they stop distributing/passing through DHCP addresses to clients. This happens roughly every 2 days, at which point I simply reboot them all and magically the clients get addresses again and everything is OK for another couple of days.
I don't think it's the DHCP server (Win 2012 R2) since it still gives out addresses on wired clients when this problem occurs.
I have upgraded them all to the latest firmware and tried running them in a cluster (single point setup mode) and separately with the same SSID. Problem occurs in both modes.
If I give my wireless interface a static IP, I get full network access, so I don't think there's any routing/switch config issues.
Any ideas please? They're under warranty but I have no Cisco technical support contract. I could try get them all replaced but it seems unlikely to be a hardware fault with all 4.

Sadly this issue is not resolved. I am on site today and could not get an IP address when trying to connect to the wireless network. This was affecting 2 of the 4 WAPs on the site. The one I normally have the issue with is working OK.
I then plugged directly in to the LAN but still couldn't get an IP address so I suspected a DHCP server issue or rogue DHCP server on the LAN. I stopped the DHCP service on my server and did not get an IP address, so I don't think there is a rogue.
I started the DHCP service and still couldn't get an IP address (wireless or wired). I then opened the DHCP console and noticed the server address was '169.254.x.x'! Never seen this before, so did a quick bit of research and this led me to disable all the NICs not in use on the server and restart the service again. This seemed to fix the issue and the server name came back up in DHCP instead of the 169 address.
I could then get IP addresses on the wired connection only.
I could not get IP addresses on wireless until I restarted (pulled the plug) the 2 WAPs.
Really puzzled with this one but it seems as though everything could be a knock-on effect of an issue with the DHCP server.
Anyone come across similar behaviour before? Although I don't suspect an issue with the switches, I will post the config here anyway (please see attachment). Maybe someone will spot something strange in there.
You will see the interface that the DHCP server and WAPs are connected to in the interface descriptions.

Airport Extreme best practice configuration for Sleep Proxy, DHCP/NAT and PPPOE

Hi
I have recently bought a Airport Extreme and it is working well. One of the reasons I bought is to take advantage of the Bonjour Sleep Proxy on it so I can wake my MAC up remotely from my iPad using the REMOTE app to stream things like iTunes etc... I followed the set up instructions and basically let it configure itself. I have an ISP router / modem which currently is providing DHCP services, NAT and PPPOE.
The Airport detected all of this and set itself up as bridge only. The speed of the network outo to the internet is fine (more or less what it was before). However, in doing a bit of research, I have found out that if I want the Airport to act as a sleep proxy, I need it to "host" the network. I am not an expert in networking but from what I understand I need the Airport to be moved from "Bridge Only" to at least be providing DHCP to my internal network clients.
This has prompted me to ask what is "Best practice" when it comes to configuring the Airport given I want to have Sleep Proxy enabled. I think the two options I have are as follows but would really welcome feedback on which is the best option to go for or if there are other options I should be thinking of
(1) Have the Airport perform DHCP for my internal clients and leave the ISP router/modem doing NAT
(2) Have the Airport perform DHCP and NAT. I think to do this I need to turn the ISP router / modem into Bridge mode only. (I've looked and I seem to have this option on the device. It's an Irish ISP branded device but I think it is a Zyxel)
I have no reason to believe the ISP router / model is doing a bad job but given I understand the Airport Extreme is a reasonably high-end device (I think?) I am wondering if option 2 is the way to go.
In addition, during my research, I have also discovered that many people seem to have their Airport Extreme also handle PPPOE. This is currently being done by my ISP router/modem. I am inclined to leave it this way (following the mantra if it isn't broken, don't fix it) but if there was a good reason to have the Aiport do this, perhaps I should make the switch? Having said this, I have seen on this forum and others, some posts about problems with Internet connection drops when the Airport is handling PPPOE.
So, a bit of a long post, but if anyone has any information or perspective on this, I'd very much appreciate it.
Thanks
Dave

I forgot to thank you, John Galt. Yap, it solve my problem by restoring back the original firmware to 7.6.1. My unit is Airport Extreme 2012. I am still using double NAT because I cannot figure it out on how to set DHCP only in the Network tab.
My goal it to use the airport extreme to the internet and to share the internet to all my devices in the house. Just like my previous Accesspoints. Before I use AP+router Linksy$ WRT54G and D-l!nk DIR-655 without activating the NAT to share my internet connection and they work.
My problem is that when I set it to DHCP in the internet tab and DHCP in the Network tab in Airport Utility inorder to solve the double NAT situation, only one of all my devices (wired or wireless) can connect to the internet. Each time I connect the other device(s) to the internet my subscriber will verify my subscription (web browser based verification) in which I have to manually enter my account number, etc to validate my subscription.
So I stick to double NAT so that I can share the internet
Our broadband provider uses DHCP to link us to the internet. If I change the settings to Static in the Internet Tab, my broadband provider will not let me connect to the internet. In the Airport Utility if I set to static in the Internet Tab inorder to set it to solve the double NAT, a message box appear informing me that I have invalid beginning IP address in the DCHP range in the Network Tab when it appears that only the last 3 digits of the DHCP range is editable.
Is there any way of configuring the Airport Utility's Internet TAB to DHCP and Network TAB to DHCP to connect to the internet with all my devices without the double NAT and without the aid of another device such as AP or router or switch connected to the Airport or vice versa?

Random Services Stopping (DNS, DHCP, SMB, etc)

Hello,
I have been trying to wrap my head around this, but we have a single Xserve 10.5.4 and it runs the the majority of the services here in the office, like DNS, DHCP, AFP, SMB, Web, Software Update, Open Directory, and more. The problem I've been having is that over the weekend some of these services just stopped. Not all of them, and in the most recent case SMB, DNS, DHCP, and Software Updates stopped. The server was up the whole weekend, people were in the office saturday working just fine but not on sunday. So where do I even begin to look on this? Some other things you might want to know is that we are dealing with an internal packet loss issue due to cabling, we have been troubleshooting out various bad lines in this office and preparing to have these lines repaired, but to be honest, I can't see how packet loss would cause services to stop on this machine. What do you think?

This is what shows up in the log. I have not seen this in the log before as I have been digging through it to troubleshoot the issues here (I'm new to this company and have been trying to wrap my head around their issues)
I checked into where that MAC address belongs and I have found that it belongs to the server itself, which seems strange that it's reporting that the duplicate IP is being sent from the server that's reporting this error, it shouldn't be reporting itself as a duplicate correct? I feel like I'm reading that wrong, but in looking there are no DNS errors like the ones you mentioned. I turned up the log reporting for DNS to be more verbose, hopefully that will turn something up.
Thank you for responding so quickly.

HTTP Load Test - Stop Proxy info to be set by open Script

Created a HTTP Load testing script in OpenScript. As soon as the browser(Firefox) opens up, the HTTP proxy settings were set to localhost: 7777.
Our application would not work on that proxy. Please help on how we can override the proxy details.
I tried the option in View -> OpenScript Properties -> Record(HTTP)-> Use broswer's proxy. It did not work either.
Please help.

Hi
Port 7777 is the proxy that OpenScript uses to record the HTTP traffic, if you are using a proxy to access the application you will need to chain it.

Airport Extreme has stopped doing DHCP

I have been really happy with my Airport Extreme N until lately, it seems to be flaking out on getting an address from the Cable Modem. My setup is Cable to the modem, modem to an ethernet hub that goes all over my house, the Airport Ex is plugged into an ethernet jack in one of the rooms, it has been working fine... Until recently. I unplugged the ethernet cable from the back of the Airport Ex and plugged it directly into my MacBook Pro. No problem. Immediate connection. So it is the stinkin Airport giving up the ghost?
wave_man

The AEBS is like any other piece of equipment - it can die - but it can also get 'confused'. Try two things before assuming there's a hardware issue. First, power it off and let it sit for a good 10-15 seconds before plugging it back in. A simple restart can fix a multitude of problems. If this doesn't work, perform a reset. Since the reset will return the AEBS back to factory defaults you might want to open the Airport Utility and make a note of your settings before you do this.

DHCP stopped working for wired clients (possibly due to new Windows 8 machine on network?)

My home office network has always been rock solid but has suddenly stopped allocating DHCP addresses to wired clients (wireless still works). The only thing that has changed has been the introduction of 2 Windows 8.1 laptops for my children over Christmas, and I wonder if these are the cause?
My network set-up is as follows...
I have a fibre broadband connection into the home office which plugs into my Airport Extremes WAN port. I then have a single ethernet cable going from one of the LAN ports on the AE to a gigabit ethernet hub, into which I have 10+ machines. The AE is set to use PPPoE to get the net connection and the network setting is to use DHCP to sign addresses. The IP addresses are assigned to the wired clients, plus a couple of airport expresses, and a number of iPhones, iPads etc. This has all worked fine for a couple of years, and any device just gets an address and works.
At Christmas both my children got Windows 8 laptops (don't ask!). I connected them to the wifi network (served by the Airport Extreme) and they got assigned an IP address correctly. They can browse fine, and also auto-updated to 8.1 at the same time.
I wasn't working in the home office at that time but did notice a few things not connecting and when I did check, none of the wired devices was receiving an IP address. They all come up as self-assigned. Nothing has changed on the network itself, the cables are still plugged in (the machines haven't moved!). I think somewhere on the network a second DHCP server is running, but I cannot see where. The only new thing are the Windows 8 laptops. Could they be the problem?

I've managed to spend some time testing and here is what I found out.
Before doing anything I turned off the two PC laptops to make sure they were not available
I powered down the Airport Extreme and disconnected the ethernet cable in the LAN port
I powered on the Airport Extreme
I then connected my laptop (running 10.10) via a single ethernet cable to one of the LAN ports. The laptop had wifi off.
I checked the network control panel, and I had a valid IP address via DHCP. I checked a couple of websites and was able to view them.
I then unplugged the ethernet cable from my laptop and plugged it into my ethernet switch (keeping the there end in the same LAN port on the AE). No machine on the network was able to get an IP address via DHCP, they all came up self-assigned.
I then unplugged the ethernet cable from the AE LAN port. I unplugged one of the cables from the switch that goes to a second switch on the network and plugged that into the same AE LAN port. All the machines connected to that switch came up self-assigned and won't get an IP address via DHCP.
In summary, if a single machine is wired to the AE it gets a valid IP address via DHCP. If multiple machines are connected they don't.
With the Windows machines turned off, I now thinking they might not be the cause. BUT nothing has changed on the network to make this happen.

ITunes Proxy Authentication & iTunes Store can't connect

1) Stop Proxy Authentication Window
To solve the issue with the Proxy Authentication window coming up over and over please add the following to lines to your Proxy Configuration above the first DENY rule:
acl iTunes browser iTunes
http_access allow iTunes
2) Access Content in iTunes Store with Proxy
If you are having any issue with Content being displayed in the Store with Proxy, please follow the steps below:
In the Internet settings remove the tick next to "Autodetect" and "Proxy Server"
Launch iTunes and Connect to the Store (you should see no result when on Corporate network with Proxy)
in the Internet settings add the tick to "Autodetect" (or) 'Proxy Server" (set as you had before)
Launch iTunes and conenct to the Store, you should see content.
If you did above whilst on Corporate network with Proxy you will see badly rendered Content.
If you did above off Corporate network with no Proxy conencted to the Internet you will see the Store rendered correctly.
If you try this step once off the Corporate Network, the rendered content looks correct even when you connect to iTunes store via Proxy after the fact.

Dhcp error getState serveradmin_dhcp plug-in module

Hi!
I have a 10.8.2 server serving netinstall images DHCP and SUS. Suddenly it stopped serving IP addresses, and after checking in Server.app I got an error "An error occurred on the server while processing a command. The error occurred while processing a command of type 'getState' in plug-in 'servermgr_dhcp'.
I ga see in the log for the DHCP service that its in fact recieveing ACKS from devices but i cannot view connected clients och see the status of the DHCP service in Server.app, version 2.1.1 to be clear...
It also seems like the netinstall service is having difficulties serving clients.
No change was made to the server, but there war a pending update, the small update to 10.8.2 ver 1.0 interim update. I applied it, but nothing changed. Still same problem as before. As an attempt to fix this I removed the /var/bootpd.plist and let the service recreate it. it populated with old data?!? Where did that come from?
I then proceeded to deleting Server.app and emptying the trash, rebooted and reinstalled Server.app from App Store. config showed successful, and then the same error in Aerver.app. what is the cause of this, and more importantly, what is the fix? can I somehow reset the DHCP service? And where are all files associated with the service so I can delete them and have them recreated?

I had same problem with:
the error occurred while processing a command of type "getState" in plugin 'servermgr_dhcp'
and serverapp crash.
In terminal running:
sudo serveradmin status dhcp
It did said it was running, stopped the dhcp service in terminal
sudo serveradmin stop dhcp
Went to folder
/var/db/
did a copy to my desktop of file: dhcpd_leases
then deleted the file from /var/db/dhcpd_leases
Start Dhcp service in terminal:
sudo serveradmin start dhcp
Everythings seems to work

You can use the internal dhcp, but you need to set the primary dhcp as the management ip. So in your dynamic interface, your primary dhcp is configure with the wlc management ip address. Dhcp proxy also needs to be enabled and is enabled by default.

WAP551 DHCP issue

Hi,
I have trouble with new WAP551 accesspoints.
For supplying a new building on our campus we decided to use WAP551 accesspoints. Another building is working with WAP541 models an all is working fine.
The accesspoints are working in cluster mode with 16 nodes. They are supplying multiple SSIDs in multiple VLANs with different DHCP Servers in some VLANs.
When I start switching between the SSIDs I will not get a DHCP address. When I am going to look at the switchport, where the AP is connected, I cant see any DHCP Packet passing by. It seems that the AP stops passing DHCP. Sometimes it takes a few minutes, then suddendly a DHCP request passes by and my client gets an address.
To isolate the issue, I took one of the new WAP551 to the old building and installed it there as single AP, but it is the same there (so it has nothing to to with my infrastructure of the campus) and the WAP541 are still working fine - I can switch between the SSIDs a couple of times and always get an DHCP address.
I installed the latest firmware of 2015-01-19 - 1.1.2.3 - but no change - still the same.
I have no idea whats going on, has anybody here new ideas?

Restrict DHCP lease

HI All,
I'm pretty new to server administration. Here is my problem: I have installed a wireless AP with WPA protection. When I user requires to use the wireless facilities, I start/stop the dhcp service on the server. The number of people who have access to the
password has increased significantly, hence whenever I start the dhcp service, my dhcp pool is filled within minutes.
So, is there a way of having the service running full time, but a platform/software that can help me choose the machines that I want to allow/deny access?

Thanks for the reply. The wireless device I have does allow for MAC address filtering. However, what I wanted or would like is a form of screen showing a list wireless devices requesting access. It is from this list I can select who is granted/denied access.
Hope I have explained well enough.
