Parallel triggering of DHCP and AutoIp

In my TcpIp stack, I want to trigger AutoIp/LinkLocal and DHCP addresss assignemtn parellelly. But the response from the DHCP server is too slow. By the time I get a reponse from DHCP server the AutoIp address assignment is over and assigned to my interface (NIC). After this the DHCP frames (DISCOVER/REQUEST frames) have AutoIp address as source IPv4 address in Ipv4 header.
Is this correct?

I'm confused :/
No one has never experiment external triggering of SAP billing jobs in parallel mode?

TS1398 ipad setup - can't join my wifi, entered wrong password and now wants DHCP and other info

just got an iPad and set it up, synched with my computer. Then I turned on WiFi (to connect to my home FiOS router) and when it asked for password I entered the wrong one. So, I tried again and now, instead of prompting me for password, it's asking for DHCP and lots of other detailed info that I don't know.I tried turning wifi off and then back on ... same result when I tried to join (the DHCP et. al. prompts). I tried turning the iPad off and back on ... same result.
What to do??? I'm so anxious to try out my new iPad
(P.S. I have an iPhone and have no problem accessing WiFi. This issue with the iPad was obviously triggered by my entering the wrong password)

Go to Settings>WiFi>Your Network Name - tap on the blue arrow to the right of the name and then tap - Forget this Network in the next window at the top.
Restart your iPad for good measure and then go back to Settings>WiFi>Your home network name and start over again.

Dhcp and ethernet drivers

The normal "plumbing" for a STREAMS ethernet driver when configured is that it has open streams to the IP (sap 0x800) and ARP (sap 0x806) modules. For most drivers supporting fastpath, the IP stream's flags are set so that the fastpath optimizations are done.
It looks like things are slightly different if the ethernet driver is setup via dhcp (i.e. ifconfig driver0 dhcp). There are now two streams with sap 0x800, one with fastpath optimizations enabled, the other without. Presumably incoming IP packets should get sent up both these streams.
Can anyone confirm this? Can anyone explain why this is the case?
Thanks,
Chris

Update: I did a lot of reading and found that Appletalk is no more. I got a parallel to USB adaptor and connected the HP laserjet printer that way and it works fine. No more ethernet connection.
On my HP PSC 1350, I discovered since the OS up grade, I could not scan and the printer utility will not function. The only software HP has for this printer for Snow Leopard is PRINT ONLY. I did find software on Apple's site which I believe is for OS 10.7 and that works (sort of), Utility still won't work and the scan function is cumbersome to operate. It is disappointing that Apple and HP cannot be more in concert concerning up grades and keeping the ability to operate existing equipment. My next printer will be a Brother next time I need ink cartridges!!

Problems setting up Verizon DSL (DHCP) and AirPort Extreme

I have Verizon DSL with DHCP and old router (Linksys WRT54G). I've bought iMac and new router (AirPort Extreme) to connect to iMac wirelessly. I have a Windows computer connected to the Linksys WRT54G. Now here is the story. I can connect verizon DSL modem (it's in bridge mode) to PC directly and connect to the Internet. When I plug AirPort between the DSL modem and PC, auto-configuration doesn't work, AirPort utility says there is problem with internet connection. Router simply can't obtain IP address from verizon's DHCP server. I've tried to copy DNS server addressed from the IP configuration in Windows, the AirPort light went green and Windows indicated connection as successful, however I still cound't browse the Internet because gateway is not set. Any ideas how to make AirPort connect to the internet using DHCP instead of manual settings? I can try to do it from the mac if needed, I don't think it would make any difference though.

Welcome to the discussions!
Sorry, I can't quite track exactly what you are trying to do.
What would the network that you are trying to set up look like?
Modem>AirPort Extreme>Computers? Are you saying that you won't be using the Linksys in the new setup?
Sounds like you need to set the Airport Extreme up to supply PPPoE service (which the Linksys is doing now-if the modem is in bridge mode), but I will wait for your response before offering specific info.
If you've been fiddling with settings, we may need to do a hard-reset on the AX to start over. You should not be fiddling with DNS, etc. Almost always, these settings are done automatically when you have the device set up correctly.

Apple Airport Extreme Base Station for PPPoE, DHCP and NAT with ActionTec DSL modem

I just spent several hours trying to track down proper instructions for setting up my Apple AEBS to do the PPPoE, DHCP and NAT while connected to an ActionTec M1000 (no wireless module). It turns out my initial set ups on both devices were correct, but that the order for rebooting and reconnecting the two devices is critical. All of the threads I found on this forum and on many others suggested this was not possible, but it is. What I don't yet know is whether it is the best method for running my home network DSL connection to my ISP (CenturyLink).
The instructions I found that worked come courtesy of Brandon Konkle's blog and are both simple and clear: http://brandon.konkle.us/post/19637529637/centurylink-actiontec-q1000-airport-ex treme-bridge
The proper settings for the ActionTec DSL Modem can be found under Advanced Setup/IP Adressing/WAN IP Address
Click RFC 1483 Transparent Bridging then click on Apply.
(see also http://qwest.centurylink.com/internethelp/modems/m1000/pdf/M1000_BRIDGE.pdf )
To reduce time, do this BEFORE you reset your AEBS then set the AEBS so that you don't have to wait for the AEBS to reboot.
In contrast to what Brandon described for the Q1000 modem, my AEBS never reconnected to the modem (he describes his as getting an IP from his ISP, then dropping it then getting another over and over - mine never got an IP). Once you have reset both devices as described, the critical steps I have not found described elsewhere were:
1. Disconnect the power from both the modem and the Airport Extreme.
2. Disconnect the Ethernet cable between the two devices
3. Restore power to the 2 devices and allow them to fully reboot. For the ActionTec M1000, this is indicated when the lights stop blinking. (Note that the Internet light will NOT be lit in this instance since the modem is acting only as a bridge. You will NOT have an Internet connection until the AEBS is reconnected.) The AEBS will be blinking yellow.
4. Reconnect the Ethernet cable between the devices (make sure on the M1000 that you are using the connector with the circle icon over it, not the arrow icon).
Within about 60 seconds, the AEBS light went to steady green and the connection to the Internet was restored.
Now I have to see if this is a more stable configuration than the flaky one I had before while using the AEBS as a bridge and the M1000 to do everything.
Does anyone think or know if it will make a difference?

No one can accurately predict in advance what the actual results might be. I've tried both ways with different products and cannot say that one method is better than the other. What works is best.
In theory, it is preferable to have the modem provide the PPPoE connection service since it is the device connected directly to the Internet.
In practice, results vary depending on the service provider, products used, phase of the moon, alignment of the planets, etc.

Non-ISP DDNS with Apple DHCP and DNS Services

I have two questions about Dynamic DNS (DDNS) as it applies to Apple's DNS and DHCP services within my home network. I am not talking about DDNS in the context of making my external-facing router available by a domain name on the Internet using the dynamically-assigned IP from my ISP.
Starting with Snow Leopard Server, I attempted to use Apple's DNS and DHCP services (I have the firmware-based DHCP service in my router turned off.) The difficulty I immediately faced was that Apple's DHCP implementation didn't update the DNS service as IPs were handed out to DHCP clients. Because of this, it wasn't possible to access hosts by their hostname, since getting a DHCP-assigned dynamic IP at boot-up didn't do anything to automagically register the hostname-to-IP mapping in DNS. Manually registering the hostname in DNS was pointless, becuase over time the client IP address can and did change. I could create static IP assignments based on the MAC address, but doing that for all of the devices on my home network sort of defeated the purpose of using dynamic IPs.
The only solution I eventually found was to go out and get an open source DHCP server, compile it for my Mac, install it, and configure it. After doing this, everything worked great; every time a new host or other device was booted it got a dynamic IP through DHCP, and then the DHCP server automatically updated Apple's DNS serive with the hostname and assigned IP. I could immediately access every device on my network by hostname. As IP addresses changed over time, the hostname-to-IP mapping in DNS was automatically updated.
Except, Apple's point upgrades kept breaking my non-Apple DHCP install. Every time I applied software updates to my server I had to go back and re-finagle DHCP to get it to automatically start and run. By the time Lion Server came out, I drank the Kool-Aid and went back to Apple's DHCP implementation. I was disappointed that it still didn't seem able to update DNS with hostnames as it assigned IPs, but I was so tired of mucking about at the command prompt to fix DHCP every time Software Updates broke it, I just lived with the inconvenience of not being able to access devices on my network by hostname.
I'm sorry to say this, but Windows Server has had this capability since at least server 2003. In fact, until I dumped my Windows Server and switched to Snow Leopard Server, I was running Microsoft's DNS and DHCP services on Server 2003 and they did exactly what I'm describing brilliantly.
Can anyone offer any advice here? Does Mountain Lion's implementation of DHCP allow for DDNS updates to the DNS service? If not, how are other people handling this? Should I go back to running Windows Server for my DNS and DHCP services? My Netgear WNDR3700 router appears to have the standard, substandard DHCP server in firmware as most home routers, and no facility for DNS at all--much less the ability to update an on-site DNS sever with IP addresess it hands out. In fact, the only appliance I know of that does this is the InfoBlox my employer uses, but that's too expensive for a home solution.
As a Post Script, I'll add that I've been VERY unhappy that I lost the ability to bind Windows clients to Open Directory under Lion Server. Since I'm starting to see articles that say this capability hasn't been added back to Mountain Lion Server, I'm seriously considering implementing a Windows Server AD master and establishing a "magic triangle" or "golden triangle". If I end up having to do that, I wonder if I might as well just go back to using Microsoft's DNS and DHCP services.

Hi,
Whether to move your DHCP to another server depends on the workload of your server. If there are too many clients on the network, you should move your DHCP to another server.
Did the record which owned by the machine generate before you configure the DnsUpdateProxy group? You can try to regenerate the record and check the result.
For more detailed information, you can view the link below.

How to set up DHCP and NAT for QNAP NAS MyCloud service?

I have an Apple AirPort Extreme Base Station (AEBS) attached to my DSL model (no router in the modem). My QNAP NAS is attached via ethernet to the QNAP NAS. My iMac (running AirPort Utility 6.x) is connected to the AEBS via wifi.
I've found several folks who've tried this (and apparently succeeded) but I'm a networking novice and am having trouble making this work. What I did was to go into the AirPort utility and in the networking section configure "DHCP and NAT" and then called out the static IP and MAC address of the QNAP NAS (as well as the ports I'd like to remain open). However, when I did this and applied the changes, my iMac (connected to the AEBS via wifi) could no longer see the AEBS, which then required me to reset the AEBS, re-configure it back to the previous known good conifiguration and start over. After about 5 cycles of this I gave up.
So, what am I doing wrong here? Do I need to go in and configure every device that is going to access the AEBS as static and call out each device's IP and MAC address? (hopefully not, that'd be a major PITA).
Help. Anyone?

DHCP and mtu size in rc.conf

Is it possible to set an interface to use both DHCP and a custom MTU size by setting the value in rc.conf?
I tried using the line "eth0="dhcp mtu 9000", but that did not work.

There is a hackish way to do it:
eth0="dhcp"
eth0mtu="eth0 mtu 1234"
INTERFACES=(lo eth0 eth0mtu)
It is important that eth0mtu is after eth0 in INTERFACES.

RV320 DHCP and WAN questions

Hello all,
So far I love the RV320 its super fast and works really good (with 2 WAN connections).
I though have a few questions hoping someone could tell me:
1) Under DHCP Server it gives the option of to use DNS from ISP or DNS Proxy, what is the main difference between those two options?
Right now I have this set to DNS from ISP.
2) What are the pros and cons of enabling IPV6 DHCP and what is the best setting for that (Yes both ISPs I have suppor IPV6)?
3) What is the best option to set as client lease time for DHCP? (its set to 1440 default).
4) On the System Summary page I see both WAN1 and WAN2 connected (i set it to
Load Balance (Auto Mode) but for WAN2 i always see: Connected (Inactive)
Why does it say inactive?
Thank you!

Found answers to most things now except for:
4) On the System Summary page I see both WAN1 and WAN2 connected (i set it to
Load Balance (Auto Mode) but for WAN2 i always see: Connected (Inactive)
Why does it say inactive?

Solaris 10 x86 u5 dhcp and jumpstart install fail

hello
I have problem in solaris 10 u5 jumpstart install.
I can use jumpstart install with dhcp and get a static ip address (assigned by dhcp server) before solaris 10 u3.
But now I can't use jumpstart install in solaris 10 u5 without setting up a static ip address in sysidcfg.
I have many x86 machines.
If I have to set up every different sysidcfg for every machine when I install a new machine.
I will get into big trouble.
here is my sysidcfg

Edited by: cheung79 on 2008/4/19 ?? 5:29

I think that you should modify the script discovery-install, so you'll be able to create the sysidcfg file dynamically. I had the same problem as you and there is a possibility to add some arguments to the boot command that you execute at the ok prompt. These arguments can be defined in the discovery-install script. It's quite easy.

DHCP and FTP issues.

I have a server setup running server 2012 R2 with DHCP and filezilla for FTP, and a desktop running windows 7. The server can ping the desktop, but
the desktop can not ping the server, however the desktop can get a DHCP address from the server. How can I get it to connect to the ftp service? I choose to use filezilla because I could not get the anonymous logon to work for IIS.

Hi,
Have you checked windows firewall on the server side if allows ICMP, by default firewall is on and blocking ICMP.
http://www.sysprobs.com/how-to-enable-ping-on-windows-server-2012-r2-firewall
Also see if port 21 for FTP (assuming filezzila using default port) is allowed in firewall.
Hope this helps.

DHCP and QoS

Hi all ,
I'm looking for some way to base the QoS in my LAN on the host's IP address . Of course , there'r many hosts in that network , some of them get their addresses from the DHCP and anyway the question is - is there any way to make the class-maps based on the host without enter the commands manually ? Maybe bind them to DHCP allocation ? Obviously , ACL will do the job but with many hosts on LAN that task becomes very complicated (to me and ,maybe the router too ... just think about many ACLs and MQC commands related to any one among these ACLs) . The perfect solution will be some sort of template , which became active for any device in the LAN ... grouping all together into some "global policy" running on the router . As it happens to be for remote-access clients (L2TP for instance) .
I'd appreciate any advice ,
have a nice day ,
Alex .

Hi Alex,
I dont think so that you can make class-maps using hostname.
if there are good number of hosts, you can create a separate VLAN for them and make a ACL for that particular subnet. so this way your ACL wont grow..
hope this helps ..

Bootpd, DHCP and OS X Server 2.2

I have a Mac Mini running OS X Server in Mountain Lion that I use for imaging via DeployStudio. A couple of days ago, I tried to boot a MacbookPro using Netboot by going to Start-up Disks, and selecting the Netboot image. When the machine restarted, it just sat at the grey screen for about a minute, then it started flashing the globe icon, as it was trying to find the Mini. After about a minute of that, it would give up and then boot back to the OS. I tried this with a NetInstall image, another NetBoot image, another machine, and so on. All of them had the same behavior.
After going through some logs and looking at the documentation, it turned out that the machines really couldn't find the Mini to boot from. Basically, if the DHCP service wasn't turned on, and configured for the same subnet that the Mini was on, then nothing could find the Mini to boot from it. This was bad, really bad, as l work for a large achadimc instatution where they run their own DHCP services for all of the subnets.
The issue turnes out to be that as of 2.2 of OS X Xerver, that the bootpd service doesn't launch by itself anymore. The DHCP service must be running for bootpd to launch. Netboot needs bootpd for the clients to find the host. The solution that I came up with was to modify the /etc/bootpd.plist file.
There are, as of when I am writting this, two versions of Netboot. Netboot 1, or old Netboot, allows the bootpd service to run without DHCP, and Netboot 2 that requires DHCP to be on for bootdp to launch. I went into the /etc/bootpd.plist file and added the following lines to the bottom, just before the closing </dict> tag:
<key>old_netboot_enabled</key>
<array>
<string>en0</string>
</array>
This turns on the old netboot so bootpd could run on its own. You'll have to restart the machine running OS X Server for the change to take affect.
There a couple of downsides to this method. One is if you turn on Internet Sharing in the Sharing system pane, or if you happen to turn on or change the DHCP settings in any way, your changes will be wipped out.
I hope this helps somebody out that that had the same issues that I had.
Micah

Hi Micah,
I have try your solution but it doesn't work.
First Excuse me for my english writing 'cause I'm french...
So the problem is complex, here is my Situation :
Netboot Server : A brand new mac mini server with 10.8.2 server (late 2012, macmini 6,2), 2 terabyte hard drives of each and DeployStudioServer 1.5.16
The services Netinstall, OpenDirectory (master mode) and AFP file sharing are all ok !
I have an external DHCP (linux) server. The DHCP server is on a vlan and the netboot server and netboot clients are on another clan, so I have
add ip address of my netboot server as a ip-helper address in the cisco router configuration of the dhcp server vlan.
And HERE IS MY PROBLEM :
I have used three kinds of netboot's client :
1. a macbook pro 17" (macbookpro 5,2, 17" early 2009) with mac os 10.6.8
2. a macbook pro 13" (macbookPro 9,2 13" mid 2012) with mac os 10.8.2
3. a Mac mini late 2012 ( macmini 6,1) with mac os 10.8.2
I have generate 2 DeployStudio Netboot sets, one for the macbook pro 13 " (10.8.2) and one for the mac mini late 2012 (10.8.2)
SO, It works without problem when I netboot with macbook pro 17" which use for example the netboot set of macboo pro 13" but the other machines don't net boot ! Why ???
In the netinstall logs and when I netboot with macbook pro 17 under 10.6.8, I saw the lines :

Using eDir as backend store for DHCP and DNS

With SLES9 you can use LDAP as the backend for DHCP and DNS? Can you do
this against eDIR? How? Do you manage it within iManager or still using
the YAST2 tools?

Hmm, haven't tried that. I guess that it would be quite tricky. Even if
you did manage to do it I don't think iManager would be able to see the
config.
