Issues of IPv4

• Export VM organized all information

  So, I managed to get 75% of what I seek to extract vcenter and export it to a CSV file. I'm trying to get some information that will help me maintain the vCenter environment that I'm working on. I guess that the first problem, I'll answer, is what is the best way to get to the bottom of the IPv4 address only? At the moment I'm getting the IPv4 and IPv6 protocols. When I connect to the server vCenter using PowerCli and then run this command:

  Get - VM | Select Name, @{N = 'IP address'; E = {[string]: join (",", $_.)} Guest.IPAddress)}}, NumCpu, MemoryGB, Notes, PowerState. Export-Csv-path "c:\temp" - NoTypeInformation

  I get a CSV file with a number of data points, and everything looks good except the issue of IPv4. I tried to add only the host or NetworkAdapters for data points for, but it did not work. I go about it the wrong way, or is there a better way to obtain these data points?

  Thank you!

  The guest.ipaddress property is an array that contains all IP addresses (IPv4 and IPV6) that are configured within the guest OS.

  You can use a Where clause to get the IPv4 addresses only

  $regIPv4 = "(?: (?: 1\d\d |))" 2 [0-5] [0-5] | 2 [0-4] \d|0? ([1-9] \d|0?0?\d)------.) "{3} (?: 1\d\d | 2 [0-5] [0-5] | 2 [0-4] \d|0? \d|0?0?\d [1-9]).

  Get - VM | Select Name,

  @{N = 'IP address'; E = {[string]: join (",", ($_.))} Guest.IPAddress | {{(où {$_-match $regIPv4}))}}.

  PowerState, Notes, MemoryGB, NumCpu |

• Wifi MacBook - ipv4 vs ipv6 issues

  Hello

  I use an Airport Extreme edition last, software 7.7.3, to distribute the connection of my Internet service provider. The router DHCP, Airport Extreme is only a wifi router.

  I have many devices connected with happiness at the Airport (iPhone, printers, my macbook), however my friend's macbook 13' sometimes fail to connect to the internet. I can't know for sure it connects to the airport at all, but it seems because it has an IPv6 address. I read somewhere on a forum that it could be related to ipv6. And indeed when I change the settings of 'Link-local' only airport, it connects in IPv4 and it works like a charm.

  No idea if it's a bug of macOS or bug Apple Airport will address?

  Thank you.

  This is a bug and there long... Set the link-local Mac only for IPv6 on the wireless or ethernet, depending on which is used.

  Auto which is by default gets it wrong more often.

• X 1 carbon PXE Boot issues

  First of all Hello to everyone, and sorry if this has been asked / solved before... I couldn't find the option to search for the forum (its beginning, my brain is still asleep).

  I have problems with getting the carbon X 1 to perform a PXE boot, I connected to the network via the Lenovo USB / Ethernet adapter, and when I press F12 option LAN is here. This is where the problems begin.

  It you press ENTER to boot via the NETWORK card, the screen is black and the text "> on IPv4 PXE boot" is displayed, it takes about 30 / 40 seconds before heading to the start menu. He never starts with Ghost. I have double checked that I have the TFTP, the PXE server and the Ghostcast Server works (and has been tested with a Vaio).

  Anyone else see this issue? Correction of this problem?

  Thanks for reading and any help would be greatly appreciated

  
  

• The G7 Pavilion Internet connectivity issues

  Help! I'm working on a laptop for a consumer, and I'm stuck hard. The laptop is a G7 Pavilion with Windows 7 64 bit. The machine was given to me under the principle of "The Internet does not work". Properties with wireless and LAN settings say that the laptop is connected and it has Internet access. I can ping outside the machine address and can ping the machine from other devices. It is also a valid ip address according to an ipconfig. However, when you try to pull on a Web site, there is a page "Web site is not found." This happens on IE, Firefox and Chrome. All drivers ethernet drivers, chipset and wireless drivers were uninstalled and reinstalled. They are the latest drivers available on HP website. I even replaced the wireless NIC thinking it's maybe just a bad card. I checked the IPv4 settings and all is good. Think to any DNS problems, I tried using directly the IP to connect to Web pages, but all without success. I'm quite baffled and need advice. Is there BIOS problems that adversely affect this? Any suggestion would be appreciated.

  Hey Darken_Rahl,

  Hmmmmmmm... interesting.

  Are you able to ping to an IP address?

  I don't think that you are dealing with a hardware problem, it must be the establishment / OS related.

  This really looks like a DNS issue even if IP navigation does not work. You have emptied the DNS? If this isn't the case, please do so now:

  1. Press Windows Key + R.
  2. Type cmd , and then click OK.
  3. Type ipconfig/flushdns and press on enter.
  4. Test.

  Also try these in an elevated command prompt:

  1. Start.
  2. Type cmd in the search.
  3. Right click on cmd/prompt commands and run as administrator.
  4. Type netsh I I r r and press ENTER.
  5. Type netsh winsock reset , and press ENTER.
  6. Restart.
  7. Test.

  Let me know the results of those.

• Issue with Vista wireless

  Computing:   I have a Dell XPS 420 Desktop Computer with wireless capability with a Broadcom 802.11 network adapter g. operating system is Windows Vista Home Premium 32-bit with Service Pack 1

  History: I had my computer since December 2007 and used to access wireless internet with Bellsouth DSL and a Linksys router, and then for the past year, I got paired with a Linksys WRT150N router comcast. I have had no problems to connect to the internet until Verizon Fios has been installed on the Sunday, August 30, 2009.
  That said, I tried with a Dell laptop in windows XP and it is connected. I also tried with a mini computer dell laptop running XP and it is also connected. Yet once again, I say that all three of these computers connected to the internet using Linksys and two different ISPS, it was with the switch to verizon that it has lost its ability to connect.

  Verizon has installed a router wireless Actiontec MI424WR Rev E.
  Firmware version: 20.9.0 (this is the most to date version)

  I can't connect my Dell XPS 420 desktop using a wired LAN connection to the router and establish an internet connection. I'm not able to establish a wireless internet connection. When I try to go wireless, it is said:
  Public Network - unidentified network - Local access only.
  IPv4 connectivity: Local
  IPv6 connectivity: Local
  Media state: enabled
  SSID: FWLK5
  Speed: 54 Mbps
  Number of employees: (all 5 bars)
  Bytes received is always 0

  On the connection tab:

  Network availability: all users
  The checkmarks are: connect automatically in case of beach, connect to a more preferred network if available.

  On the Security tab:

  Link layer topology discovery map i/o driver
  Link Layer topology discovery responder

  Sharing:
  The two boxes are checked:
  Allow other users to connect through this computer network
  Allow the other network users to control or disable the shared connection
  
  What I've tried so far based on reading previous forums discussing this issue.

  1. completely uninstalled Norton 360, including using the Norton removal tool and by calling the customer service of Norton who has accessed the computer and verified the complete removal.

  2 turned off the windows firewall.

  3 make sure the Broadcom network adapter driver has been the most up to date.

  4. people with disabilities and reinstalled the card network Broadcom.

  5 update Windows Vista Service Pack 1 and all other updates installed today.

  6 call Verizon Online support - they reset the modem and tried several things like change the "channel". Nothing has worked. They said to contact the computer manufacturer. They have pointed the finger to be a problem with Vista from the computers Windows XP work.

  7. called Dell: they tried several things with access to remote and says that it is the problem of the router/ISP.

  8. unplug the router several times, waited 5 minutes and plugged in. Has made several rounds of power on the computer as well.

  9. changing a registry key according to Microsoft technical support to disable the DHCP Broadcast flag in windows vista (I'm not entirely sure I did correct it because I didn't know what was the GUID) http://support.microsoft.com/kb/928233

  10 disabling IPv6 (by unchecking it)

  11 disabling IPv4 (by unchecking it)

  12 Ran IPConfig to confirm I have a valid IP address (starts with 192 and is valid I don't know if I should post the full address)

  13 fact MSCONFIG with reset winsock

  14 changed the settings TCP/IP by netsh int ip reset at the command prompt, and out, and then uupon done restart ncpa.cpl in the start menu and unchecked the tcp/ip v6 Protocol restarted the computer.

  15. don't attempt to ping a website - no Exchange packets, error message cannot find the Web site. I tried www.google.com and www.verizon.com

  I am at a loss of what I can do to get my computer back operational wireless. Due to the entire office to the top of our House, I would really like this computer on another level and the only way to accomplish that without drilling the holes through the walls that it it works wireless.

  Any other advice would be greatly appreciated, thank you.

  UPDATE:   I rented the "Geek Squad" to come look at my system. The poor guy spent 3 hours going through all stages. Finally a last ditch effort he has installed a new NIC card. Bingo that fixed for some reason any. Apparently, the old NIC card was bad, even if the system was saying that it was good. The old NIC card was allowing him to connect to the router but no internet. He said it was weird, but the problem is SOLVED!

• Dynamic DNS update of IPv4 addresses does not not in Windows 7

  Several months ago, we noticed behaviors incompatible with Windows 7 clients and their entry in DNS Active Directory.

  The main problem is that our Windows 7 clients only will be not systematically their IPv4 address in Active Directory DNS by using dynamic DNS (RFC2136)

  Initial question:

  • A handful of customers will register its IPv4 address, but it is a minority and most don't (this is the main question)
  • We use the public IP address space.
  • Customers have been constantly recording the IPv6 address for 6to4 in DNS card but not its IPv4 address.

  We have disabled the 6to4 map by using Group Policy, because we do not use IPv6 and don't plan to use the 6to4 transition.

  Secondary issue:

  • Customers is no longer recording card 6to4 in DNS (good)
  • Majority of customers do not yet record their (bad) IPv4 address.

  What I've checked so far:

  • Analysis using Wireshark:
    • Most clients make no request for SOA record and therefore do not try to send dynamic DNS updates.
    • Some customers get the AD zone SOA record and then send the DNS dynamic update to one of the DCs.
    • I see nothing of clearly different on clients who send updates and those who are not.
    • All the other AD related traffic, for example request/response for domain/ldap SRV record looks normal.
  • Settings on the client:
    • The IPv4 adapter "save addresses for this connection in DNS" checked.
    • The primary DNS suffix is the same as our AD domain name.
    • The AD domain name is a COMPLETE domain name.
    • Use us group policy to apply the primary DNS suffix and some connection specific suffixes.
    • Customers do everything they are supposed to; as access to shared resources, printers, etc. - just not update DNS.

  I read all of the following, but I'm no further forward:

• Prefer IPV4 to IPV6

  Even if we do not have IPV6 enabled on all types of adapters our domain servers and windows 7 desktops still seem to resolve IPV6 addresses. We run a Microsoft difficulty he 50410 and this solves our problem but only for a short period of time. Not sure what made it back but always seems to come back eventually to the solution in the form of IPV6 addresses.

  I understand the difficulty he 50410 makes some registry changes that might prefer IPV4 to IPV6 and, by the way, works fine but once more for a short period of time. A few days or more.

  Can someone let me know what registry changes, making it so I can put them in a group policy that applies to all machines on our field?

• Extension mobility / CAD issue: "You cannot connect because the phone is compatible IPV6"... help please.

  Hi all

  I'm having a problem with the mobility of the extension and CAD.

  UCCX 8.0.2.10000 - 41

  8.0.2.40000 - 1 CUCM

  CAD 8.0 (2)

  Phone: 7945G (configured according to other phones no 'contact center' of society, but not 'line' unaffected - want them purely for Contact Center users to connect to their posts)

  When the user logs in the phone itself, there is no question at this point.

  When the user goes to sign in CAD, they are presented with the following error:

  "You cannot connect because the phone is IPV6. IPv6 compatible phones are not compatible with CAD. »

  Workaround is to unlock (settings > * #) Network Configuration on the config of IPV6 phone and physical removal.

  Settings > * # > 2 (Network Configuration) > 2 (Configuration IPv6) > button 'more' > 'Clear' button > it presents 'clear IPv6 network settings '.

  The user can then successfully connect to the CSA.

  The problem is that, after his shift, the user logs on to the phone, then when they log in again, the question is again presented and the 'workaround' to manually remove the IPv6 configuration out of the phone must be done all over again (and each time after that too). Arrrrg.

  I also noticed that in CUCM > devices > Device Settings > Commond Device Configuration > find > my CDC > the IP address Mode IS set to "IPV4 and IPV6.

  A test, I've changed that to "IPV4" only

  User logged off phone, phone rebooted, logged in user, has attempted to connect to CAD, same problem. No change! Ahh some more!

  Finally, I discovered an alternative (to avoid the issue and the previous workaround)... CUCM, I put devices > phone > find > select > sub-heading ("phone Configuration') 'Extension Information' >"Logout profile"profile of mobility of users and then we do NOT have the issue. Phone restarted, connected, do not connect you, tried all the different States - everything works fine now.

  I also found that by setting up a 'line' on the device - the problem is also solved.

  HOWEVER, I don't really want to specify a line configured to the individual if possible phones or mobility of the specific user profile.

  Is it possible to avoid this? What Miss me to avoid specifying a line or a profile on your phone?

  See you soon,.

  Hi Brett,

  I saw something similar once I installed UCCX 8.x to a customer.

  Workaround there had to be a SU installed on the UCCX.

• SGE2000P loses the manually configured ipv4 address after reboot

  I am setting up a new switch SGE2000P as independent. As part of the Setup, I need to assign a new IPV4 address to the switch default instead a 192.168.1.254. After that I applied the changes everything works fine, but when the reboot of the switch get the ip address back to the default. Any contributions to this issue will be appreciated.

  Elkins

  Hello Evillalona,

  I just looked at the issue you are seen and wanted to check with you on this subject.

  When you change the settings in the switch then go to the file management section

  the switch and make a copy of the running configuration to the startup configuration? I just wanted to

  check and see if that would fix the problem you are experiencing. I've heard other people with

  the same problem and that was the difficulty for them.

• FlexBuilder 3 constantly crashing (VISTA) and other issues

  I encounter some problems with the FlexBuilder 3 Beta:
  1. FDI almost always blocks (leaving behind a Java Runtime Error dialog box) after stopping a debugging session.
  2. If the IDE do not crushed after a debugging session, you cannot debug again. You get an error indicating that the debugger is still working. When it is not. I find that I "end task" (using Task Manager) a task called ieuser.exe I am able to start debugging again.
  
  These two issues make it practically impossible to play with FlexBuilder 3.
  
  Anyone having any questions?

  I understood earlier finally workaround for the occasional problem when using Flex Builder on Vista, where Flex Builder tells you that another debugger is already running.

  The solution is to add this line to flexbuilder.ini or eclipse.ini (the name of the ini file depends on if you have installed stand-alone Flex Builder or Eclipse of Flex Builder plugin version):

  -Djava .net .preferIPv4Stack = true

  That's all. I suspect a bug in Vista - the first time that you are debugging, I see clearly that Flex Builder is the closure of the socket, but when I run TCPView, it shows that the IPv6 version of the socket is always open, and that causes the problem. The addition of the definition of the above property causes Java to use only IPv4.
