• Unknown to router in the Network Infrastructure

  Hello

  There is a unknown router which is not mine not appearing in the Network Infrastructure.

  I understand why it show up under available wireless networks. But not the network infrastructure.

  I have not connected to it, is not my router, and it is not there. It is a little disconcerting, to say the least.

  Here is a screenshot:

  Cisco Wireless VPN router - N is mine.

  WNR1000v2 isn't.

  Is this a security risk? Why is this, and how do I get rid of him?

  Thank you.

  OK so I would like to know what criteria determines why a router is listed in the network infrastructure... and how to get rid of him?

  Why is windows 7 this? It makes no sense at all...

  Can't really answer. I can only say that turning on the Details view for the page shows that the alien router isn't listed in my network location. A network infrastructure device is that in theory I 'could' connect to research a little further into the router configs (properties because it gives model, series No, MAC address and unique identifier #) indicates that the owner has set up to use WiFi Protected Setup to allow wireless devices to connect (requiring a fixed number of pine).  So, if I had the PIN to the router, I was able to connect to its network. Maybe that's why it appears. If your mystery router is configured in the same way, this could be a further indication as to why these routers being listed in the title of the Network Infrastructure while all other neighboring routers are not.

• Why are there two routers listed in the Network Infrastructure?

  I have a Linksys WRT54G2 router, but sometimes when I look at my network in the control panel it shows an extra router, that router ghost appears in the title of the Network Infrastructure. It's a WRT160N. Sometimes it's there, sometimes it isn't.

  I have Windows 7.

  Why this is part of my network? Should I be worried? How can I stop it arise?

  On a thread, the user was able to match the MAC address of the window of the Network Infrastructure to an open wireless network (unprotected) nearby. This seems to be the case for multiple threads, I found elsewhere on the internet.
  Given that I have found so many other similar threads on the same issue, I would consider it is safe and I would just ignore it.
  If I find a solution to them, I'll let you know!

  If you have configured during the installation of node2 part of the cluster. Right.
  >

  Right.

  After the installation of the Network Infrastructure, I can create an ASM instance to create groups of ASM disks for data files. Right?

  If you have not configured the DSO during installation, you can use ASMCA to create and config instance ASM.

• Problem on installing network infrastructure - SCAN name and IP addresses

  People,
  
  Hello.
  I was installing RAC Oracle Database 11 g 2 system with 2 Virtual Machines (rac1 and rac2) in 3 VMPlayer.
  
  I set up ASM. Now, I want to install the network infrastructure for rac1 and rac2 using runInstaller.
  
  I type in 'rac-cluster' in the name of SCANNING box in the wizard.
  According to my understanding, SCAN IP addresses are used to connect to the shared database. 3 IPs SCAN for shared rac1, rac2 and DB are automatically assigned during the installation of the network infrastructure. I need not specify IP SCAN 3 addresses in the file/etc/hosts.
  
  But when installing on step 3 of 8 grid infrastructure, the wizard appear this error message:
  
  "Invalid name SCAN - insoluble in IP address. SCAN name: rac-cluster cannot be resolved. »
  
  
  Any folk that understand how to solve the problem above (name SCAN & IPs) on step 3 of 8?
  
  Thank you.

  Hello

  YES requires the SCAN name. SCAN name is the host name.
  Without DNS, you can set the name of the SCAN on the file/etc/hosts.

  The hosts file can resolve the IP address only 1 for 1 hostname.
  Specify a SCAN name on your file hosts of two nodes (same IP address).
  And only one resource SCAN VIP will be created.

  ex.
  $ grep rac-cluster/etc/hosts
  192.168.1.100 rac-cluster
  * the two node address

  And specify 'rac-cluster' on the name SCAN of YES.

  Good luck.

• After uninstalling the grid Infrastructure: virtual host name [INS-40912] assigned to another system on the network

  Hello

  I deleted successfully installed grid Infrastructure software. Now, I installed again it but the installer complains about '[INS-40912] virtual host name assigned to another system on the network", which he complains not in the first installation process. :/

  EDIT: I checked and both nodes of the cluster are interpingable through their virtual IP address.

  I see that the previous installation has created a clean interface for this virtual IP address:

  eth0:2	Link encap HWaddr 00:50:56:B9:0E:AA
  	INET addr:10.200.11.159 Bcast:10.200.11.255 mask: 255.255.252.0
  	RUNNING BROADCAST MULTICAST MTU:1500 metric: 1
  	Basis of interruption: 19 address: 0x2000

  OK solved: I just do:

• Get airport utility to forget the other devices on the network view

  Hello

  Is it possible to get the Airport utility to forget other devices, it's on the graphic display? I live on a college campus so it displays about 15 other aircraft from the airport in the vicinity of my home and I would like to see it just mine! When I was updating the name and password on my base station, Airport utility gave me the option when I clicked on the other devices to 'Forget' them, but as soon as I close, then reopen the Airport utility all return and the only option I have to then when I click on another device must enter the password for it (which of course) ", I do not have).

  Outside him cluttering up the graphic display, I wonder whether, if all these devices are recognized as part of 'My network', is sometimes interfere with my access internet and wi - fi as the speed and the same connection seem to go up and down like a yo-yo (sometimes up to 90 Mbps but also weaker than 0.05 Mbps - less than the old dial-up!). I have been informed by our IT Department University detects a problem with your local network, it can "bleached you' which cuts or slows down your connection into a net - and if all these devices are considered by Airport utility as part of my network so I'm guessing that a problem in one of the base stations that could affect the rest.

  So, is it possible to get just the Airport utility will display only my own base station (Airport Extreme) over a wi - fi (Airport Express) extension?

  Excellent question...

  First airport utility keeps a history of all the airports that he never sees and even if you select forget he never forgets... you need to dip down and remove the plist... as with all things Mac.

  / Users/youusername/Library/Application Support/Apple/AirPort/SavedTopos/Topo-nIfc=en0,nHsh=00000000.plist

  There are a lot of them dated for every time the network topography change. Close airport utility and delete the entire lot... a new will be created when you restart.

  What OS you are using... There is an option... but I'm not sure it works... to show only devices you set up.

  So, open airport utility preferences. Click monitor airport basestations for problems... then don't watch that airport base stations which I configured... Tell me what happened to him.

  

  Outside him cluttering up the graphic display, I wonder if, if all these devices are recognized as part of 'my network ',.

  No, it's just the airport utility is a bit too excitable to find other airports of apple around the place and wants to watch all the...

  They are not part of your network... but in small areas Wireless will cause problems... it, without doubt. Most of the colleges banning people who run their own wireless routers because the result is what you feel... CHAOS.

  There are 3 channels for 2.4 ghz and perhaps 6 or 7 for 5 GHz Wireless AC must so much bandwidth, you have more than 3 or 4 channel without overlap... This means that for every 3 airports you have exhausted all channels... (and all airports after it's battery on the mill).

  15 other aircraft from the airport in the vicinity of my home

  So that means at least 5 airports are run on the same channel you are on average. Wireless was never designed to ensure that the density of life. It's only the airports... think how no apple routers wireless there's around you that are not displayed.

  Open any program wireless diagnostic... There is a built-in to your Mac. see how many names wireless mac can pick up.

  I highly recommend that you stick to the use of the 5 GHz band using a different name... and choose depending on the channel works best for you. No Auto and just stick...

  You'll never find that it works without problems... but there is no doubt that life is easier if people started to build a faraday cage to live in or used ethernet.
