    Is if the city offered free Ubuntu CDs as "Windows Upgrades."
    • by Anonymous Coward on Saturday September 01, 2007 @11:46AM (#20433965)

      Ubuntu is an upgrade from XP and Vista.


      Keep that shoe on the other foot for just a little longer. Imagine them having "support scripts" that travel through a KDE interface instead of Outlook Express or IE. Imagine them requiring Ubunto to install your access. In short, imagine all of the "standardization" Windoze enjoys being flipped on you.


      In the free software world, users can edit a few well annotated text files to get the job done if they are given the proper information. That task is harder in Windoze because you must dig through several GUIs that don't tell you what to ask for in advance or ever.

      My company ran into this as well. We have 4000 wireless customers spread out on 20+ antennas (each with its own Cisco switch). We're a Microsoft partner so we contacted them about the problem right away.

      As I understood it, the bug was this: Vista will only accept broadcast replies to DHCP requests. Any multicast response is discarded for security reasons (!?). So their solution was to put a DHCP server on every level of our network (for us, one for every 200 users) or switch to a network that relayed the broadcasted replies (ie: hubs). They also told us it wasn't a bug so they wouldn't issue a patch to correct it. There was a KB article on the issue but when we had users call MS support and ask them to walk them through applying it, we got a bunch of angry calls back to us saying MS refused to help them with it. We also talked to Cisco a bit to see if they had any idea what we could do to relay the broadcast but they never got us a solution.

      So in the end, we told MS that we'd either need a better way to fix this or we'd just tell our users not to use Vista. They seemed okay with us telling users not to use it so we have. A few of our users still use Vista with a home router and that seems to work alright. Luckily, there aren't too many Vista users yet and when faced with the option of buying and configuring a router or buying and configuring Windows XP, they've decided on XP. So all in all, it wasn't that big of a deal.

    The university I work for in Sweden began testing with Vista when it was the called Longhorn. We discovered some bugs with the communication between Vista and some of our servers (running Solaris) back in 2004. The bug repports were submited to MS back then and the thing was fixed on the next Longhorn beta "release". It seems it's easier for some not to test and cry out like a baby when it's too late.

    The problem as reported is that the Vista DHCP client fails to obtain an address from Linux servers running (I'd presume) ISC dhcpd.

    When I bought a laptop recently it came with Vista. When I connected it to my network it failed to obtain an address. I assumed there was some misconfiguration problem I was missing, Turns out it's a fundamental difference between the DHCP client in Vista and the one in prior versions of Windows. See this item from Microsoft: http://support.microsoft.com/kb/928233/en-us [microsoft.com].

    The version of dhcpd I'm using is an old one (2.0). I thought about upgrading it to see if that would solve the problem, but since I wasn't planning on keeping Vista on the laptop, I didn't bother upgrading. All our other machines run Linux and don't have this problem.

    I wonder what decision will be made in enterprises running Linux DHCP servers that introduce Vista into the workplace. Will they follow the Microsoft KB item above and "fix" the problem on every new Vista box they buy? Or will the replace the Linux DHCP box with Windows Server?

    • by click2005 ( 921437 ) on Sunday September 02, 2007 @11:03AM (#20441443)
      RFC2131 states:
            A client that cannot receive unicast IP datagrams until its protocol
            software has been configured with an IP address SHOULD set the
            BROADCAST bit in the 'flags' field to 1 in any DHCPDISCOVER or
            DHCPREQUEST messages that client sends. The BROADCAST bit will
            provide a hint to the DHCP server and BOOTP relay agent to broadcast
            any messages to the client on the client's subnet. A client that can
            receive unicast IP datagrams before its protocol software has been
            configured SHOULD clear the BROADCAST bit to 0.


      RFC1542 States

      3.1.1 The BROADCAST flag

            Normally, BOOTP servers and relay agents attempt to deliver BOOTREPLY
            messages directly to a client using unicast delivery. The IP
            destination address (in the IP header) is set to the BOOTP 'yiaddr'
            address and the link-layer destination address is set to the BOOTP
            'chaddr' address. Unfortunately, some client implementations are
            unable to receive such unicast IP datagrams until they know their own
            IP address (thus we have a "chicken and egg" issue). Often, however,
            they can receive broadcast IP datagrams (those with a valid IP
            broadcast address as the IP destination and the link-layer broadcast
            address as the link-layer destination).

            If a client falls into this category, it SHOULD set (to 1) the
            newly-defined BROADCAST flag in the 'flags' field of BOOTREPLY
            messages it generates. This will provide a hint to BOOTP servers and
            relay agents that they should attempt to broadcast their BOOTREPLY
            messages to the client.

            If a client does not have this limitation (i.e., it is perfectly able
            to receive unicast BOOTREPLY messages), it SHOULD NOT set the
            BROADCAST flag (i.e., it SHOULD clear the BROADCAST flag to 0).

                  DISCUSSION:

                        This addition to the protocol is a workaround for old host
                        implementations. Such implementations SHOULD be modified so
                        that they may receive unicast BOOTREPLY messages, thus making
                        use of this workaround unnecessary. In general, the use of
                        this mechanism is discouraged.


      If XP can receive unicast IP datagrams. why cant Vista? Either MS broke Vista or the TCP/IP stack is less functional than before. Either way, use of the broadcast flag is discouraged.

      The Microsoft article you reference notes that the whole problem is caused by a single flag (the DHCP BROADCAST) that Vista sets and previous Windows versions didn't. The article also contains the following quick and easy solution:



      RESOLUTION


      Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.


      To resolve this issue, disable the DHCP BROADCAST flag in Windows Vista. To do this, follow these steps:

      1. Click StartStart button, type regedit in the Start Search box, and then click regedit in the Programs list.


      User Account Control permission If you are prompted for an administrator password or for confirmation, type your password, or click Continue.

      2. Locate and then click the following registry subkey:
      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\Parameters\Interfaces\{GUID}
      In this registry path, click the (GUID) subkey that corresponds to the network adapter that is connected to the network.

      3. On the Edit menu, point to New, and then click DWORD (32-bit) Value.

      4. In the New Value #1 box, type DhcpConnDisableBcastFlagToggle, and then press ENTER.

      5. Right-click DhcpConnDisableBcastFlagToggle, and then click Modify.

      6. In the Value data box, type 1, and then click OK.

      7. Close Registry Editor.


      So Vista isn't (formally) going counter to protocol, it's just going counter to a 15-year old custom. Nonetheless, Vista *can* cooperate, it just needs to be told not to raise the DHCP BROADCAST flag. And yes, that route goes via a registry modification.


      In summary: a tropical storm in a teacup.

        They got it right back in 1995 (12 years ago) ... and they're changing it now.

        In summary: a tropical storm in a teacup.

        Nope. Just another example of how Microsoft does not care about published standards. Their DHCP services can handle it so why should they spend any time understanding the standard that the rest of the world follows?

        After all, everyone else will probably change to support Microsoft's weird implementation. Who cares about the problems that the users have in the meantime? If Microsoft is lucky, no one will be able to explain the problem in terms those users could understand and the rest of the world will be blamed for the problems when it is Microsoft who is not following the published standard.

      "Which implementations support or require the broadcast flag?
      The broadcast flag is an optional element of DHCP, but a client which sets it works only with a server or relay that supports it.

      Microsoft Windows NT
      DHCP client support added with version 3.5 sets the broadcast flag. Version 3.51 and later no longer set it. The exception is in the remote access support: it sets the flag when it uses DHCP to acquire addresses to hand out to its PPP clients.

      Microsoft know exactly what the problem is, and know exactly how to fix it. They are being deceptive in their claim that they're not doing anything because Lundis are not cooperating. The bug is that they have decided to implement a legacy feature in DHCP, one that servers are not required to support, as being on by default in Vista. This was a legacy feature in 93, so there's no need for it to be on by default. In fact, the standard which specifies the flag states that the flag is for cases where you have no choice but to use it. The fact that it can be turned off in Vista shows this is not the case.

      There are also reports that Cisco equipment won't work with it either.

It took the manufacturer a good three months to come up with a new firmware that addressed the problem, and until then we had to teach hundreds/thousands of customers how to use telnet (and how to install it if they were running Vista, the telnet client is disabled by default). Good times...

    Bad news guys; Microsoft isn't the one with a bug causing the problem. Poor implementation yes, bug no.

    For some bizarre reason Vista expects the address returned from the DHCP server to be broadcast, instead of sent via unicast packet. This is permitted in the specs and supporting the broadcast flag on the server is suggested. ("SHOULD", not "MUST" in the spec.).

    When researching this I found 2 network types which required this, Infinibad and 1394 (Firewire). It looks to me like Microsoft picked the one which would (theoretically atleast) work on all network types, instead of only on a few.

    Of course, this is a typical bad decision as it means that responses from a DHCP server with a lot of Vista clients will flood the network with broadcast responses, but hey, they arent know for making good decisions.

     
  • The very pithy Inquirer article says:

    he reason is because Lund is a Linux city which has a a Linux server that doesn't like Vista.

    This implies that it's Vista refusing to interoperate with Linux, which obviously would play into story submitter twitter [slashdot.org]'s frequently-espoused odd Microsoft conspiracy theories. In actual fact, it's a recognised bug [microsoft.com] acknowledged by Microsoft as being due to old routers or DHCP servers which do not support the DHCP broadcast flag (a formal part of the DHCP RFC standard).

    Solution:

    • Every one of the DHCP servers in the world, on every OS whether embedded or multi-purpose should be audited and downgraded (yes, this is a downgrade to a deprecated method) or replaced with obsolete equipment.

      This should be done because Microsoft's Vista network programming team could not be troubled to code in something like "If DHCP request using deprecated method times out, retry with the standard method."

      And no copying my idea. That's valuable Intellectual Property there.

    [Microsoft]: Okay, do you have any data on why not?
    [Town]: no but it's your fault, fix it!?!?
    [Microsoft]: Well, what's even a short description of the problem? Side effects? Can your Linux server be changed to alleviate it in the meantime?
    [Town]: THE INTERNETS IS BROKEN, FIX IT THOUGH OKAY!!!!????

    Yeah, all Microsoft's fault. If this was on Mozilla or Novell or Linux bugzillas it would have been closed as "irrelevant".

    Right people here are discussing RCFs and wonder what is going on, well I live in Lund and here is my take on what has happened:

    a)Per the RFC servers do not need to implement the broadcast flag, but it is a good idea if you want to support systems that use it.

    b)Per RFC Vista doesn't need to clear the broadcast bit, but it is strongly recommended and setting it is intended for legacy clients only.

    c)Lund's energi's network doesn't support the broadcast and thus Vista machines do not get an IP over DHCP since they set the broadcast bit.

    d)For reasons we don't yet know, Lund energi won't implement a workaround on their server. I don't know enough about DHCP or their systems to tell why, so I guess there might be a technical issue or perhaps they are just being jerks.

    e)The fix is to set a registry key, which is easy for technical users, but a pain for those who don't know about it.

    My judgement is that Lund's energi has a shitty DHCP server and Vista is a shitty DHCP client. Since the fix is so simple ( adding a registry key ) this really ought to be a non-issue, but because Microsoft and Lund's energi are both incompetent crappy companies the end user is left with a problem that would actually be rather easy to resolve. Those in the know can work around it, but non-technical users are left without service while those responsible point the finger at one another. The sad thing is that this really isn't particularly surprising. Hmm, did I forget something? Oh yea, the article summary is wrong since there are scores of ISPs in Lund, and this only affects one of them. So yea, I'm not very surprised at all...

    From my understanding of the problem, Microsoft is no longer supporting the unicast response for DHCP like it did previously, even though that is the recommended way to do this. While Microsoft's implementation is valid (though not recommended), I can see why the ISP doesn't want to honor it. If a lot of Vista subscribers start doing this, there could potentially be a lot of broadcast packets. I.e. each time a Vista user connects, the DHCP server would send a broadcast response to everyone on the local subnet (which can be quite huge).

    I remember scanning the broadcast network traffic years ago on my cable modem and it was tens to hundreds of DHCP requests packets per second. If most users start running Vista then this would double the broadcast traffic.

    Broadcast should be avoided unless absolutely required.

    It is very interesting how the ISP is blamed here. He could, he should, yada yada. M$ delivered a broken configurations and the ISP has to fix this. Generally not wrong. However, as Linux user I wonder a bit, why he should do this? I have enough examples where ISP refuse to support Linux. If it works, fine. If not, problem of the user. I never heard similar ISP blaming comments about this in any forum. More likely: "Oh yeah, Linux is the outsider, only 0.00001% of all user use it, heh heh heh."

    And how often do I hear about the superiority of Windoze. When some WiFi card does not work under Linux: Linux is not fit for the general desktop. If some WiFi card does not work under Vista: The stupid manufacturer was not able to deliver proper drivers on time.

    I begin to think the only reason that Windoze works at all is because everybody bends over for M$ and paves their path.

    Sorry, but even if those voices, which say the ISP could have acted on behalf of their customers, are right, and they are, I still deem them hypocrites.
