More info needed on MAC address

Hi,
I have a post in the same forum regarding a problem I have been having since I moved last week: I am getting a self assigned 169 IP address and can't therefore connect to the Internet. I have been doing many things and nothing has been working...
However, I am able to connect to a PC without any problem...And I found a way to connect with the Macbook but it's only good until I restart: I use the MAC address of the PC and I change my Macbook MAC address for the one I see on the PC through a command in Terminal and bingo, I can connect (until I restart and I guess take back the Macbook MAC address).
I don't know much about Mac address so if there is anyone who can explain to me what is going on, it might help me to fix this issue once for all!! It seems like the modem likes the PC MAC address better!!
Thanks!

Small world
-I don't see any actions possible on the MAC address 'page'.
-Only the Mac is hooked to it (there is only one ethernet socket).
-In another page (of the modem's web setting page), there is this message:
Resetting the cable modem to its factory default configuration will remove all stored parameters learned by the cable modem during prior initializations. The process to get back online from a factory default condition could take from 5 to 30 minutes. Please reference the cable modem User Guide for details on the power up sequence.
...That's what I should try giving your last comment.
It's bed time soon in Helsinki but I will post again this week end...Hopefully, it will be to say that it is solved
Cheers,
Julie

    Try printing your printer's network configuration report. It should show up as one of the line item.

  • More Info Needed in Message Tracking Logs in Exchnage 2010 MAILBOX

    Hello All
    I would like to understand more on message tracking which was little bit confused for me 2 days back.
    As far as i can know, HUB SERVER is  the main part of the messaging tracking is playing  vital role in Exchange 2010.
    also, mailbox roles too...
    i can see the message tracking logs created in mailbox is only usefull , for  web interface for message tracking is part of the Exchange Control Panel and provides very basic search
    functionality to search for messages either sent by or received by a mailbox, based on the sender, recipients, and subject line.  
    so message tracking logs which is available in mailbox is only user for end users who can perform the message tracking by themself vua ECP without installing EMC. -- AM I RIGHT  
    How will message tracking logs created in mailbox servers .......... will it replicate from HUB servers?  
    so if i have 4 mailbox servers, will all the mailbox servers having the same message tracking logs? or we may get different
    Your information is much valuable to better understand on MT

  • Modeler error messages - more info needed!

    Dear Friends,
    I got an error executing a planning sequence of function type  'generate combinations'.
    The system messages on the top section of the modeler  are :
    1. first message :
    "Planning function Gen Combinations ( ended with errors"
    2. subsequent messages are in green (no error) 
    "Context information for the other messages"
    3. Selection for characteristic xyz : Single value 123  (no error)
    :  <  similar ok messages follows >
    2nd Error message :
    "Cannot generate combinations for MultiProvider 'AGGR_LEVEL'"
    this is followed by
    3rd Error message :
    "Cannot generate combinations in step 'xx'"
    When double clicked on these error messages in the modeler, nothing appears to show more error info.
    Could you experts kindly let me know how can I find out what these errors mean , specifically:
    1. For the 3rd error, how can I know what is the step 'xx' about that the system is referring to where it cannot generate combinations?
    2. What does it mean cannot generate combinations for multiprovider? Could you tell me more about what this means in terms of where is the problem?
    Thanks in a advance!!
    regards
    YHogan

    Dear Gregor,
    For a planning sequence using planning function of type 'generate combinations', in general does this process work in the following sequential step ? :
    1. check the filter
    2. generate the combination based on filtered values
    or    is it the other way round?
    I am trying to know where the error lies since it errored so early in the process , about 3 seconds upon executing the sequence via program RSPLS_PLSEQ_EXECUTE.
    I set break point on the class mentioned to no avail as the generate combinations sequence ended with error very early in the process.
    I also set breakpoint on the characteristic relationship class used as well as standard variable exit include program. Also to no avail as the program errored before these stages as none of the breakpoints appeared in debug mode before the error.
    The error message is " cannot generate combinations in step '04' "
    Kindly could you shed more light on this error in terms of what it is referring to?
    Is the problem with master data , filter or characteristic relationship?
    Based on my testing done with breakpoints, seems that its not filter or characteristic relationship error.
    So, does this mean master data error?
    How could master data be having error?
    Most characteristic relationship used are attribute types. There are 2 using classes.
    Thank you in advance.
    regards

  • FOR HMARKOVA! HELP! More info needed!

    Hi, Helena! I was wondering if you could give me more detailed information about how to use arguments within two modules. I've just read your explanation!
    I want to connect to modules, I want to select a customer from one module called clients, and then pass that argument into another module called courses. I've created an argument in the called module, if I've understood you correctly this is the module called courses, in the properties I've put defined by clients.name .
    In the calling module clients, in the section
    Called Modules I've added in Argument Passed Values , but I'm not quite sure about what I'm doing.
    Could you explain how to connect two modules using arguments with more details please?
    Thanks ! I would appreciate thaT!

  • More info needed on BC Dynamic menus and using CSS with them

    Hi all,
    The BC Gurus tutorial on Dynamic Menus and how to style them with CSS made no sense to me, unfortunately. The presentation was too rushed and the screen too small to see what was happening.
    In a previous question I found out how to apply CSS classes to BC menus after a bit of a run around.
    I was putting the # in front of the Item ID name and a . in front of the class name and this was not necessary.
    I have further questions though, as I am still struggling to get a BC Dynamic menu to style properly with the CSS I have created.
    1. If you choose CSS as the menu type, can you set the font, background colour and rollover state of the menu items in the Dynamic menu section? Or do you have to style it all in the CSS stylesheet?
    2. If you choose CSS as the menu type, the option to say how the submenu sits under the root menu disappears. So do you need to set this in the CSS stylesheet? And if so in which element? UL or LI?
    3. If you choose CSS/HTML only, how is this different to the option of CSS for the dynamic menu?
    4. If you choose CSS as the menu type and if you set a width and height in the menu item, and then set a different width and height in the CSS stylesheet, which width and height wins?
    5. If you want a dynamic menu to show on an Android phone, do you have to choose CSS/HTML only and do all the styling in the CSS stylesheet? Or should you avoid dynamic menus all together and just use a UL list in the template? (I am doing a responsive fluid grid layout in DW for the template).
    6. I am finding that the dynamic menu I have done, with CSS as the type, does not show and hide the sub menu items properly on an Android phone. Is there a problem with the javascript in Dynamic menus?
    Thanks for any help you folks can give on these questions!

    .pacnew files are only created if you have modified the default (or a change has been made to the config upstream); in both cases, you should be looking to incorporate the changes.
    It seems some new options are being shipped with lxdm: you want those in your config (turning them on or off is a matter for you and the man page to sort out)...

  • More info needed about using wifi in high reflective enviroment

    Any hints are appreciated.

    Thanks for your reply Mat,
    The cleanroom enviroment (ASML semiconductor industry) is a large room about 30 * 60 meter and 7m high. In this room are smaller cabinets (about 20) where the actual work is done. Here you can see some pictures:
    http://www.brecon.nl/images/brecon_brochure.pdf
    In full production there are about 120 engineers working with their 802.11b/g equipped laptops.
    Every wall, floor, ceiling, door is made with aluminium sandwich panels. We have major troubles getting a reliable wifi enviroment, and also DECT and GSM telefony is hardly working at all.
    Right now we have 10 AP's is the large room, and we are contemplating installing 1 AP in every cabinet with low power setting and using attenuators. We are also considering the use of leaky coaxial cable.
    Migrating to 802.11N is not really an option since the clients are b/g equipped.

  • Airport ID (MAC Address) on MacBook Pro?

    Where can I find my Airport ID (MAC Address) on my MacBook Pro? Also on my Time Capsule? I'm getting ready to set up MAC ID access control on my network and need the MAC Addresses for each of my network access devices. Thanks!

    martywrites wrote:
    I certainly appreciate these replies, but need a little more clarity. I went to Airport Utility > Manual > Summary and found two Airport ID's, identical except for the last digit, suggesting that they're my two Canon MP990 printers which are operating normally in Wi-Fi mode.
    no. printer IDs will not show there at all. all that you see there is for the time capsule only. those must be two ids for 2.4 GHz and 5GHz modes which are separate. there should also be an ethernet addresss ther I would think. you might want to verify this by asking on the TC forum.
    But when I use my MP990s to print out their MAC ID's, they're completely different from any Airport ID on the Airport Utility Summary.
    correct. see above. to find the MAC addresses of the printers just print out test pages on each. that info should be included there.
    Then I found an Ethernet ID, which I can't identify with any particular device on the network.
    that's the ethernet MAC address of the TC itself.
    Maybe it's the MacBook Pro, or maybe the Time Capsule itself.
    How can I set up an accurate list of which device has which MAC ID so I can have some control and add or remove as needed. I need accurate ID's for my two MacBook Pro's (the second one will arrive Christmas Eve), iPod Touch (which I'll open on Christmas Eve), the two printers, and (if needed) the Time Capsule itself. Thanks!
    we told you two methods of finding MAC addresses of every computer. either use network system preferences or system profiler via apple menu->more info->network
    I haven't got an ipod touch (that would be the only kind of ipod with a mac address) but this page explains how to find the MAC address of an ipod touch.

  • Multicast mac-address Nexus 7k

    Hi,
    i'm going to use Nexus 7000 in Data Center.
    During analysis configuration, I need define mac-address-static configuration for multicast mac address for Firewall Checkpoint cluster.
    In "Layer 2 Switching Configuration Guide, Release 4.1.pdf" documentation speak about
    "Configuring a Static MAC Address
    [..]You cannot configure broadcast or multicast addresses as static MAC addresses[..]"
    Have you a suggestion to manage this problem and why is it not possible configure mac address static multicast?
    Regards
    Dino

    Joseph - The ClusterXL A/A configuration is a variation of the  StoneSoft or Rainfinity clustering technologies that have been used to  cluster Solaris and other *NIX flavored servers and firewalls for  years.  (In fact, StoneSoft filed suit against Check Point in Europe 8  or 9 years ago for patent violations, and lost.)  These configurations  were very common on Check Point clusters running on Solaris from the  late 90's forward - and, as you describe, have unicast IP's with a  multicast MAC for the VIP.  Even from the days of installing these on  the brand new (at the time) 2900 series switches you had to do exactly  as you state above - static MAC entries (or in some cases port mirrors)  so traffic was directed to both active switch ports.  In Active/Passive  mode Check Point ClusterXL clusters are almost always "plug and play"  today - rarely do the switches need anything beyond speed/duplex  settings.  The VIP assumes the MAC of the physical NIC it is currently  bound to, and therefore there are no issues as far as switch config or  proxy ARP entries on the gateways.  All of these issues have to do with  traffic flowing to the VIP and through the firewall, and the ability of  the switch to correctly identify which physical switch port(s) the VIP  is currently patched in to.  This is one of three types of traffic  associated with ClusterXL itself.  The second is state synchronization,  which is accomplished through a crossover cable and therefore not  relevant.  Even when using a switch state sync is a typical TCP 18181  connection from a unicast IP/unicast MAC on one gateway to the other  through a dedicated interface pair.
    The challenge described by CJ is not with the traffic  flowing to the VIP, however.  It is an entirely separate process - Check  Point Clustering Protocol (aka CPHA if filtering in WireShark) is  essentially the heart beat traffic.  Every interface pair within a Check  Point cluster continually communicates with its "partner" interface on  the other cluster members.  If any packet takes over 100ms or shows more  than a 5% loss the gateway is forced in to "probing" mode where it  falls back to ICMP to determine the state of the other cluster member.   Depending on the CPHA timing settings an active gateway will failover to  the passive in as quickly as 500ms or so.  ClusterXL will fail over the  entire gateway to the standby to avoid complications with asynchronous  routing.
    Out of the box, CCP is configured to use  multicast, but it supports broadcast as well. To change this in real  time (no restart required) simply issue the command:
    cphaconf set_ccp {broadcast/multicast}
    At  the Ethernet level, CCP traffic will always have a source MAC of the  Magic MAC of 00:00:00:00:xx:yy where XX is the “Cluster ID” – something  identical on each cluster member but unique from one cluster to another,  and YY is the cluster priority (00, 01, etc.) based on the priority  levels set on cluster members within Dashboard on the cluster object.  The destination MAC will always be the Ethernet broadcast of  ff:ff:ff:ff:ff:ff.
    At the IP level the source of CCP  will always appear as 0.0.0.0. The destination will always be the  network address (ie, x.x.x.0).
    Similarly in multicast mode you will see the same traffic  at the IP level but at the Ethernet level the destination will now be a  IPv4 multicast MAC (ie, 01:00:5e:4e:c2:1e).
    In a tcpdump  with the –w flag opened in WireShark and a filter applied of just “cpha”  (without the quotes) you should see a continual stream of traffic with  the same source and destination IPs on all packets (0.0.0.0 and network  IP), the destination of either a bcast or mcast MAC and the source MAC  alternating between 00:00:00:00:xx:00 and 00:00:00:00:xx:01.
    Long story short, the problem CJ is describing is a  behavior on the 7K where a packet capture taken on the Check Point  interface itself (ie, tcpdump –i eth0 –w capture.cap) ONLY shows CPHA  traffic from it’s own source MAC and no packets from it’s partner. A  tcpdump on the 7K itself will show traffic from both.
    As CJ mentioned, a simple NxOS upgrade will fix the issue per:
    This one:CSCtl67036  basically pryer to NX-OS 5.1(3) the nexus will discard packets that have a source of 0.0.0.0.  Which in broadcast mode is exactly what the CCP heartbeat is.  We bypassed this one.CSCsx47620 is the bug for the for static multicast MAC address feature but it requires 5.2 code on the 7k
    (NOTE:Additional RAM may be required for the 5.2 update)
    Also note that Check Point gateways do support IGMP  multicast groups, given that you have the correct license. It is a  feature of SecurePlatform Professional on the higher end gateways or as a  relatively inexpensive upgrade on the lower end boxes or open  platforms. For lab purposes you can simply type “pro enable” at the CLI  (without the quotes). As of the latest build there is no technical  limitation (no license check) so you can enable advanced routing  features as needed for testing in a lab. For step by step details on  configuring IGMP on SPLAT Pro go to the Check Point support site and  search for sk32702.
    This can be a frustrating issue to troubleshoot, so hopefully this helps someone avoid the headaches I ran in to.

  • IP address Confilct with Mac Address

    I have a windows server domain within which I have four mac users, three of them are using the latest version of leopard and all of them are having the same problem. This has happened three times (twice since I have worked here) and I have not seen any real resolution to the problem. The error I get "IP xxx.xxx.xxx.xxx is in use by the following mac address" happens for no apparent reason. I know very well that the IP address is not in use, and whats more is that the mac address that is said to be in conflict bound to the four diffrent IP addresses is the same on all four computers. This does not make any sense, how can diffrent IP addresses be in conflict with a device that is said to use the same mac address.
    I have identified that the mac address is given to a trunk port on one of my cisco switches. I know the switch does not conflict with the IP addresses.

    is in the same path:

  • HT5299 which is my ethernet mac address when in a retina with adapter?

    Hi,
    I need to get my ethernet mac address, but i have a macboock pro retina displays that only have wireless connection. I bought the gigabit ethernet adapter, but i need the mac address because the University system that will provide me the net connection needs it to allow my computer to the net.
    Where can i find it?
    Thanks!

    Plug the adapter into the MBP-R (*) and go to System Preferences > Network > Thunderbolt Ethernet > Advanced.
    (*) You may also have to plug an Ethernet cable into the adapter at least once. Mine has been plugged in, and I didn't check the MAC address before the first time, so I can't tell for sure.

  • Mac address - mac mini

    does anyone know how to find the mac address[not ip address] for a mac mini? i need its mac address to connect to a network?

    This solution is not applicable for Mavericks or Yosemite. If you are using either of these two OS do this: Go to System Preferences>Network in the left column choose the method you connect to network (e.g. Ethernet, WI-FI etc) click on Advanced>Hardware. This will show you your MAC Address.

  • Getting the MAC address of the iPhone

    Hi,
    In order for an iPhone (or any other network device) to access or wi-fi network, it needs to be registered. I would like to make it so that they don't have to register it every time and to do that, I need the MAC address of the device. Users will be registering via a webpage using the browser on the phone. Is there any way in the midst of that process that I can query the iPhone for it's Mac address?
    Thanks,
    Rob Tanner
    Linfield College

    You can get the MAC address for your iPhone at Settings > General > About > Wi-Fi address.
    There is not a way to query the iPhone for the MAC address to be entered automatically in the space provided when registering the iPhone's MAC address via the webpage, but it can be written down in advance for manual entry of the address.
