DHCP/Subnets/Static Maps setup question

We have a unique teaching environment where we would like both employees (with laptops) and clients to be able to plug into any ethernet port in the building or be wireless. My question is, what is the best way to set things up so that employees always get the same ip and have access to the full range of services (file services, LDAP, Internet) but customers only have access to the Internet but not internal services. I have tried using static maps for employees but for some reason, customers sometimes end up getting one of the static maps intended for employees (and I have verified that all the MAC addresses are entered correctly). I am pretty new to Tiger server so any help is greatly appreciated.

If im not mistaking your DHCP settings are overlapping with the ips you have statically assigned. To fix this reserve say 192.168.1.1-127 for static ips and let dhcp use the remainder.

  • DHCP static maps configuration using serveradmin (terminal / commandline)

    Hi there,
    I'm having much trouble using serveradmin to create new static map entries. Unfortunately using the serveradmin-tools gui isn't an option, because setting up DHCP static maps are only one small part of a much bigger script.
    I tried to manually execute every line. I've also tried the example from the command line manual, but everything without success.
    I would be very glad, if someone could help me solving this problem.
    So here is the the output of my script...
    every executed line leads to a
    "dhcp:static_maps = emptyarray"
    message.
    serveradmin settings dhcp:staticmaps:_arrayid:29d9e547-8b47-ab37-ab28-5a00be4031bf = create

  • Dhcp static maps

    Hi folks,
    I have 10.3.9 server. I would like to achieve following setup:
    a] home users should get 192.168.1.1-30
    b] guests (mainly powerbooks and macbooks) should get 192.168.1.100-130
    the guests are disallowed to connect to server via afp/smb using firewall rule.
    I created a static map in netinfo for home users and it's working correctly. However, I don't have 30 machines (1.1-30) but only 20, so I have gaps in the static maps. I'm trying to fill them using dummy records, but it looks like they are ignored. Is there a way how to do it?
    My dummy records are as follows:
    name=dummy1
    en_address=00:FF:00:FF:00:00:00
    ip_address=192.168.1.17
    name=dummy2
    en_address=00:FF:00:FF:00:00:00
    ip_address=192.168.1.18

    Well, for a start your MAC addresses are invalid. MAC addresses consist of 6 octets, your examples show 7. I don't know if that's an error in copying them to the boards or whether you've really entered them that way, so it might or might not be an issue.
    Also, you can't use the same MAC address twice. How is the DHCP server supposed to know which address to hand out when 00:FF:00:FF:00:00 has both 192.168.1.17 and .18? Again, this might just be a transcoding issue in this post rather than a real problem in your setup, but it's worth checking.
    I don't know that that'll solve your problem but it's the first things I'd look at.
    If you can't find a solution that way, consider reversing the order - put the guest addresses first followed by the private ones. That way guests will get a low-ordered IP address (say, .1-.63) while the home users get a higher address (.64-.96) - note how I've used binary-friendly numbers such as 64 and 96; while it's less obvious to humans it's far easier for the computer, especially in writing firewall rules since 192.168.1.0 through 192.168.1.63 equates to 192.168.1.0/26, or 192.168.1.0/255.255.255.192 and 192.168.1.64 through 192.168.1.95 equates to 192.168.1.64/27 or 192.168.1.64/255.255.255.224. It isn't possible to write a one-line firewall rule that covers .1 through .30 but it is with the IP address ranges I've used.

  • Where can I find the file where the static mapping allocations of the DHCP server are stored?

    In our company we are using DHCP to assign static ip addresses to our clients.
    Now we are forced to change the ip address range. To prevent changing each allocation
    of mac-address to ip-address manually with the admin tool i would like to change the allocation
    in the file where the allocations are saved. The reason ist that i just have to use copy & paste for all
    the allocations.
    So how is the file named and where can I find the file where
    the static mapping allocations of the DHCP server are stored? Is it just an ASCII file?
    Must i note anything when i change the file manually?

    From man bootpd:
    BOOTP/DHCP STATIC BINDINGS
         Static IP address to ethernet address bindings are stored in the /etc/bootptab file and in Open Directory.  Bindings specified in the /etc/bootptab file take precedence over those in Open Directory.
         See bootptab(5) for more information about the /etc/bootptab file.
         For Open Directory, bootpd looks at the /Computers records for the following properties:
    /etc/bootptab is a standard text file, while the records in Open Directory can be manipulated either through the command line, or via Workgroup Manager.

  • Offloading DHCP static mapping in 12.3(25)?

    According to the following:
    http://www.cisco.com/en/US/docs/ios/12_3t/12_3t11/feature/guide/gtdhcpsm.html
    ...configuring static addresses via DHCP can be accomplished from a text file found on a tftp server as of IOS 12.3(11)T.
    I'm running 12.3(25) on a 2621, but I don't see the form of the "origin" command described at the above link. The documentation above states that the syntax is:
    origin { dhcp | aaa | ipcp | file <url> }
    ...yet, I only see the following options:
    Router# conf t
    Enter configuration commands, one per line. End with CNTL/Z.
    Router (config)# ip dhcp pool MYPOOL
    Router (dhcp-config)# origin ?
    aaa Subnet is from a AAA server
    dhcp Subnet is from another DHCP server
    ipcp Subnet is from IPCP subnet negotiation
    Router(dhcp-config)#
    The documentation states that this functionality was released with 12.3(11)T. Am I correct in assuming that it is not available in 12.3(25)?

  • DHCP static maps ignored

    No answers on any other threads, so starting a new one.
    XServe running Server 10.6.2. Configured the DHCP service with a dynamic range and about a dozen static maps. Started the service and forced a lease renewal on a client that had a static map. Watched the DHCP messages and an address was assigned - FROM THE POOL.
    For some reason, even when receiving a request from a client with a MAC address that's defined in a static map, the DHCP server totally ignores this and hands out an address from the main pool which is obviously nonsense.
    Is anyone satisfactorily using static mapping in Snow L Server's DHCP service? Is there some 'extra' configuration that needs to be applied to tell it to use the static maps that are defined? There must be a solution to this, without it DHCP is USELESS. Surely someone has a clue about what's going on here. Please?

    I fixed my problem.
    In order for Apple's chosen DHCP server to use static maps, you have to enable this in the configuration file - something Apple in their infinite wisdom have forgotten to do.
    By default in the /etc/bootpd.plist file bootp is disabled:-
    <key>bootp_enabled</key>
    <false/>
    Change this to:-
    <key>bootp_enabled</key>
    <array>
    <string>en1</string>
    </array>
    Or for whichever ethernet interface you want to serve these addresses from.
    Well done Apple.

  • How do I remove a DHCP static mapping that will not go away in Server Admin?

    I have a static DHCP mapping to a retired network that I can't remove from the Server Admin GUI.
    To be specific, I click remove and it disappears.
    To then click "SAVE" and it comes back.
    How do I remove it manually? Where are the static mappings located that make it reappear each time I click "SAVE".
    From the DHCP logs:
    Jun 28 18:36:18 macmini-home servermgrd[97]: servermgr_dhcp:bootp config:Notice:Removed record GabrielHouse-Gateway
    Jun 28 18:36:27 macmini-home servermgrd[97]: servermgr_dhcp:bootp config:Error:Unable to update/remove record with id 45F7E04B-6368-419C-9A86-64458BBAC5C0 because 12 records found.

    Hi John,
    Thank you for taking the time to write up the approach and places to start.
    I have checked in all of the places listed and no luck. No occurance of the "stuck" statically mapped DHCP address. Just to add a note, of detail about the particular device in case this is a client device that is causing this .... The device is an iPhone and it is NOT using the bad static assignment. Also, the static record is an IP address that is now outside of the current network range..... It is 192.168.0.25 .... where as the current DHCP server range is in the 10.1.XX.XX range.
    Also, This server is not using Open Directory, but I did open WGM to see what I could see thru the GUI and I found no record in the local database.
    Also, note - I attempted to delete ALL DHCP configuration on this server by
    1) Exporting the configuration data with Server Admin
    2) Manually removing the bad DHCP static assignment in the plist
    3) Turning off the DHCP Server
    4) Deleting the full DHCP zone.
    5) Importing the DHCP configuration from the edited plist.
    6) Turning on DHCP Service.
    The bad record is back....
    Thanx for the ideas. Keep them coming....

  • Need to Import DHCP Static Maps

    I just built an 10.6 OS X Server that will be running DHCP, I have the DHCP mappings in a spreadsheet with the Description, IP and Mac address. I need a way to import them, any ideas which tool I can use?
    I have already tried Leopard Static Mapper 1.1, the plist I created with it won't load, I think it only works with 10.5

    Hi Flipwork,
    thanks for a quick update. I have checked and double checked and triple checked. I even removed the names etc. from description fields. They are simply numbers now from 1 to 1820... yea that is how many I have to import. The other fields are simple mac addresses and IP addresses.
    the plist starts to get imported in server admin and then stops at a random number depending on which order I give the csv file to static map importer from which the plist is created.
    I'll be grateful for a hint that might work for me.
    thanks again for your time.

  • DHCP static maps & Client IDs

    I'm thinking of implementing DHCP service on my Xserve. I see that when an Airport Extreme Base Station runs a DHCP server, you can create static maps with the individual computers/clients identified by their DHCP Client ID, something which I would find useful. AFAICT, this is not possible in Leopard Server's DHCP server, but it seems so unlikely that the AEBS has MORE functionality than Leopard Server.
    Am I right, or is it possible to map static IP addresses by Client ID in Leopard Server?

    Camelot wrote:
    Leopard Server does support static maps - it's right there in the Server Admin GUI.
    Yes, I think I mentioned that.
    However it's based off client MAC address, not Client ID.
    So that's a no then.
    Which means an AirPort Extreme Base Station has greater functionality than Leopard Server:-(

  • Static mapping in 10.3.x Server?

    I have a situation where we want to use static mapping (DHCP Reservations in Windows-speak) but cannot upgrade to 10.4 because of a software compatibility issue. Is there a way to enable/add this feature on 10.3.x? Thanks!

    To achieve what you want you'll need to change the server setup. Start by making your server an OD master and use different named LDAP accounts on the server for the clients (or remove/rename the local accounts (folders) first).
    The clients need to use LDAP info to find the server (look in Directory Access).
    Older OS X server versions used Netinfo domains (Jaguar too? at least 10.1.x did).

  • EA6700 DHCP Reservation (Static DHCP) limit

    Hi,
    just got an EA6700. Setup was the most difficult I've ever experienced in many years of Wifi/router config. I almost packed it back up to return it. The cloud thing is absurd. Using CAPTCHA that does not even display the CAPTCHA image is even worse.
    Alright, I succeeded in using the local admin login and set up the router. Actually the plan was to have it just be a wireless access point, using my Cisco RV042 as the router and DHCP server. Well that 'dream' was squashed right quick. That **bleep** RV042 blew up when I added one more Static DHCP entry. Poof. 'No more SYSTEM' errors in a few spots. On reboot the darn thing does not come back up. This after the RV042 needed to be reset after I used a quote or some other 'illegal' character in a static DHCP entry. What a piece of amateur junk.
    So. Tomorrow I will reset the RV042 again and relegate it to just doing WAN failover, nothing more. The EA6700 will be the router and DHCP server. So my question (sorry for the ranting) is how many DHCP reservations the EA6700 can handle. I'll probably need 75. I assign DHCP reservations for LAN stability and to prevent IP address collisions.
    Please note that I'm not talking about static IP addresses. I have a few of those too but I know they are different from DHCP reservations.
    Thanks,
       Sander

    It's highly unlikely the EA6700 can handle 70+ DHCP reservations. But I don't know for sure.
    My advice is to go back to plan A and use EA6700 as AP.
    Configure it for bridge mode. Be sure to "specify and IP address". Don't use "obtain IP address automatically" when configuring bridge mode.
    http://kb.linksys.com/Linksys/ukp.aspx?pid=94&amp;vw=1&amp;articleid=25714
    Edit: don't configure ea6700 for bridge mode while it's connected to your main router. You've probably noticed by now that the EA routers will automatically change their IP to 10.x.x.x if they detect a double NAT. Which I why I suggest keeping it disconnected from main router when configuring.

  • Bought a new Ipod touch and the WiFi does not connect.  Tried Reset and total Restore, does not connect to Router on DHCP, tried Static manually and still can not get it to connect even though it registers as connected.

    Bought a new Ipod touch and the WiFi does not connect.  Tried Reset and total Restore, does not connect to Router on DHCP, tried Static IP, Subnet, Router and DNS manually and still can not get it to connect even though it registers as connected.  Using Airport for router, latest firmware, no problems with Iphone 4 or Macbook Pro or any other internet devices.  After total Restore (factory settings) tried again, showed connected to router, but does not display "check" next to router but little rotating icon even though the wifi range signal shows connected at full strength and it says it is connected.  Just can't seem to get it to generate an IP.  Any solutions other than turning it on and off again?  Not a Merry Christmas morning.

    Ok, so, a couple of things:  Denisefromwaleska and I have the exact same size/type/color iPod.  Now wishing I'd bought the black one maybe...
    Second, Airport is an Express and I have a second one that I carry with me when I travel.  Tried to connect my Airport Express to the internet and could not although the iPod did recognize the router and tried to connect to the internet for some time, unlike my previous problem.  Updated firmware on my travel router, still could not connect to the internet.  Going to try to set up a manual Static IP on the travel router here in a few and conect through it although I predict the problem will persist. Back on the Christmas Present Airport Express router, it is back in play and working fine for all devices save the iPod. 
    Thanks again for all your help, hopefully I can get a solution in place soon,

  • CGI map file questions, help !!!

    I am trying to use the CGI map file to open web reports. I got two questions at this time.
    1. How to refresh the report to reflect resent edits ? I used the CGI map to open a report. Later, I made some edits to the report and opened it again. However, the browser showed the report before the edit. I had to save the report to different file name and edited the key in the map file to show the edited report. This should not be the right way.

    Hi Kate.
    As far as a find and replace tool is concerned, most of us
    here prefer using some tool such as FAR or BkReplacem as they offer
    more features to help in this kind of scenario. The simple answer
    is however that these tools, as indeed does the inbuilt tool, bases
    it's search on the HTML. Therefore if there are specific instances
    of HTML strings you will have to analyse carefully them before you
    replace anything. It sounds like you are already some down down
    this line. Take a backup of your project and test out your theory.
    As far as your map file question is concerned, you can safely
    reimport your map file PROVIDED that no changes have been made to
    the mapids in the meantime. Personally I wouldn't do this unless
    you are 100% sure of this. If it is a case of having 100s of topics
    that are not mapped and never have been but could be, I'd just
    create a new map file and map away.

    My guess is that it is throwing a NullPointerException because you have not set 'a' to be anything.
    The sample code you provided does not make sense.
    AddContTry is a method in the code but you are using it like a class.
    You have to set the following before you can use the object 'a'
    AddContTry a = // something
    I am just guessing here but can you write
    AddContTry a = new AddContTry();
    a.setUp();
    Note, If this is the case, the code in setUp should be in the constructor.
