Host and VMs network configuration

Hi,
We have additional Network cards on the Host hyper-v server. Does it make sense to configure Host and VM network
in this way?
Host network configuration for Hyper-v virtual network switch:
1NIC ---
2NIC --- host_team_1
3NIC ---
4NIC --- host_team_2
VM network configuration:
host_team_1 ---
host_team_2 --- VM_team_1
Would we benefit from this configuration?
Thanks

It has to be in this way:
1NIC ---
2NIC --- host_team_1
3NIC ---
4NIC --- host_team_2
VM network configuration:
host_team_1 ---
host_team_2 --- VM_team_1
I understand your point. Just idea is if we have 4 physical NICs on host server for VMs, to configure 2 teams on host server and then one team on virtual machine.

ATV2 and Manual Network Configuration Issue

Hi all,
Have 3 ATV2's in the house connected to latest gen TC via 5Ghz WiFi. Works great with one exception. From time to time, one of the ATV's loses the host iTunes library (connected via Home Sharing). If I go the the host and restart itunes - all is well again.
My solution was to try manual IP's for all of the ATV's and the Mac Mini host. Set the Mini to DHCP with manula IP- no problem.
However, when setting the ATV's, all three lose the "Movie" and "TV Shows" menu items as well as Youtube etc.. Meaning, they are obviously not connected to the WAN/Internet. They CAN see the host shared library.
Yes, it would seem my static config is wrong, BUT, I used the numbers already populated when I swtiched from DHCP. Would these numbers not be the ones assigned using DHCP? Would it not be safe to assume that simply assigning these manually would retain the same connectivity?
I switched all but the host mini back to DHCP and all is well again. However, I would like to go with a static set up. Am I missing somehting?
Thanks in advance!
Stuart

Thanks for the reply!
When you say "you also need to assugn adresses from the router" what exactly do you mean?
with exception of Mac Adress Control, I don't see a setting anywhere in Airport Utility that would allow me to assign specific IP's to specific devices...
In the past, simply setting an IP manually on a device would make it static on the network. No intervention on the TC was necessary.
Thanks again,
Stuart

Linux VM server and VM network configuration

Hi,
I have a Oracle Linux 5 server with Oracle VM Server 2.2.1 software installed. I downloaded OEL5 x86 VM template and set it up using the netmask, DNS and default gateway of the VM server machine. Now I realize I cannot access the internet from inside this Virtual Machine. So I think the DNS and gateway is not correctly setup.
Please note that I can ssh the VM from VM server.
Can you please guide me as to what DNS and gateway I should use for configuring my VMs? Do I need to set up an IP alais with different DNS.
My VM server ip is (some values changed) 99.44.95.115, DNS 213.133.98.98, Def gateway 99.44.95.97 , netmask 255.255.255.224
So for my first VM I am using ip 99.44.95.98, DNS 213.133.98.98, Def gateway 99.44.95.97 , netmask 255.255.255.224
Am I doing anything wrong. I am completely new to Linux and networking. So I am still learning.
Just a general idea would take me a long way.
Regards
CP

Netmasks are used to identify which portion of an IP address represents the network address and which portion represents the machine address. It affects your broadcast address and defines the range of addresses that you can communicate directly without the need of an IP gateway. You do not need an IP gateway to communicate with other hosts on the same subnet because they should be physically connected and hence receive each others broadcast in order to know how to translate IP to a machine address.
There are a couple of easy troubleshooting techniques. Like I mentioned in my previous post you can use the ping utility to check your IP communication. Open a terminal window and type e.g.: "ping 99.44.95.97". But make sure you do not have a firewall that block the ICMP protocol that the ping utility uses.
a) check if you can ping other machines on the same network.
You should be able to ping other hosts on the same subnet. If not, then you most likely have a problem with your IP configuration or network driver (hardware). Can you ping your own host? Is the network up?
b) check if you can ping the gateway.
If you cannot ping the gateway but a) works, then your IP gateway address is wrong or down.
c) check if you can ping the DNS.
Provided that a) and b) works, and you cannot ping the DNS server, then either the DNS address is wrong or down, or the IP gateway is not configured properly.
Please check the above in order to isolate the problem. The link to the Oracle documentation in the one of the previous replies will let you verify the vm.cfg file to check if you have configured bridged networking (default).
Posts about the same issue in different forums are usually not welcome here and the forum moderator might lock the thread. If you already have a thread I suggest you provide the link here in order for us to see what has already been done and make a note in the the old thread to continue here.

Should I leave IPv6 installed on Host and VMs

We installed our first Hyper-V server last Monday, and everything went pretty well. The first virtual machine was the main company server SERVER1, and this was running AD, DHCP, DNS. But I did have an issue during the setup for the client workstations. I
was not able to connect some of them to the domain. When I tried to ping the virtual machines, only one of the servers was being resolved (to it's FE80 IPv6 address) and the others would not resolve at all. I disabled IPv6 on these clients and immediately
they were able to ping all of the virtual machines. I thought IPv6 was meant to work alongside IPv4 when they were both installed by default, not interfere with IPv4?
So my question is: IPv6 will not be mandatory in our country for a long time yet I would think, so am I better off just disabling IPv6 on all clients and servers to avoid such issues in the future.

this is pretty worthy from Microsoft:
It is unfortunate that some organizations disable IPv6 on their
computers running Windows 7, Windows Vista, Windows Server 2008 R2, or
Windows Server 2008, where it is installed and enabled by default. Many
disable IPv6-based on the assumption that they are not running any
applications or services that use it. Others might disable it because of
a misperception that having both IPv4 and IPv6 enabled effectively
doubles their DNS and Web traffic. This is not true.
From Microsoft's perspective, IPv6 is a mandatory part of the
Windows operating system and it is enabled and included in standard
Windows service and application testing during the operating system
development process. Because Windows was designed specifically with IPv6
present, Microsoft does not perform any testing to determine the
effects of disabling IPv6. If IPv6 is disabled on Windows 7, Windows
Vista, Windows Server 2008 R2, or Windows Server 2008, or later
versions, some components will not function. Moreover, applications that
you might not think are using IPv6—such as Remote Assistance,
HomeGroup, DirectAccess, and Windows Mail—could be.
Therefore, Microsoft recommends that you leave IPv6 enabled, even
if you do not have an IPv6-enabled network, either native or tunneled.
By leaving IPv6 enabled, you do not disable IPv6-only applications and
services (for example, HomeGroup in Windows 7 and DirectAccess in
Windows 7 and Windows Server 2008 R2 are IPv6-only) and your hosts can
take advantage of IPv6-enhanced connectivity.

Solution to "unable to resolve host" and frequent network drops

Like many, I just purchased a shiny new HP Touchpad 32GB. Updated the firmware to the latest version, enjoy it's web browsing capabilities and some of the apps.
However, like many, web browsing often coughed or sputtered and would freeze often during network operations. Web sites like Google or Bing would often hang and become useless. A Google search of "Unable to resolve host" showed that I wasnt' alone.
The 'solution', or so it seemed, was to reset the network by toggling airplane mode. But doing this every 5-10 minutes, or more often, was quite frustrating. Also, other applications, such as Spaz HD for Twitter were really lethargic.
This was all a problem until I changed the MTU on my wireless router from the standard 1500 to 1300. Rebooted the modem, all is now well. "And there was much rejoicing...."
After this change, haven't had the need to toggle the Airplane mode even once. Spaz HD runs much quicker, Google & Bing no longer lock up, complex pages such as the DailyCaller.com or Redstate.com no longer time out and work properly.
I would be curious to see if others who are having the same problem, can make a similar change, and if helps them solve this issue.
Post relates to: HP TouchPad (WiFi)

For me, it turned out to be somewhat different - my home wireless was working fine with several different devices/OSs, but it seems that WebOS stopped falling back to any DNS servers beyond the first one. Whereas other devices (android phones, linux laptops, etc) still resolved DNS fine using the secondary/tertiary DNS entries, WebOS starting giving me the "unable to resolve host" error. So I changed the (primary) static DNS entry on my wireless router to one of the Google public DNS servers (8.8.8.8) and now WebOS is happy again. The only thing that changed for me (on the tablet) was enabling usbnet just to check it out, and even after I disabled usbnet, I still had the name resolution failures. Go figure...

Optimum E3200 and WRT160N Network Configuration

I recently purchased an E3200 router. I also have a WRT160N router. We have a rather large two story house, and it is not practical to run ethernet cable everywhere. I am attempting to configure the hardware I have for optimum performance given the current requirements of our family. Here is an attempt to summarize the current setup.
1st Floor
Cable Modem === Cable Box
=== E3200 === Blu Ray / Netflix
=== Laptop being used as media PC
Office PC === Wireless B/G/N Adapter
Second Floor
Kids PC === WirelessB/G/N Adapter
XBOX 360 === Wireless B/G/N Adapter
PS3 === B/G/N Wireless Adapter
XBOX 360 Headset === Bluetooth
Roaming
College Kid #1 Laptop === Wireless B/G/N Adapter
College Kid #2 Laptop === Wireless B/G/N Adapter
I can run ethernet cable from the E3200 to the Office PC without too much difficulty, since there is a basement underneath. I plan to do this. I can not run cable to any of the upstairs locations. I could set up the WRT160N as a wired AP, repeater or bridge at several different locations in the house. If I set it up on the first floor, it could be wired to the E3200, if this provided a significant performance advantage. If I put it upstairs, it will have to function as a repeater, possible a bridge. As a bridge, it could be wired to either the Kids PC or the XBOX 360. Connection to the PS3 is not a priority.
I would like to take advantage of the capabilities of the two routers to maximize the performance of our son's gaming, while not killing simultaneous multiple PC access. I have studied the process of setting up the ports for the XBOX/PS3 and am comfortable with the process, but am waiting until I optimize the router setup. I do not understand the technical aspects of how to force the XBOX/PS3 to connect with a particular router/band depending on how I utililize the WRT160N.
So, my questions are;
1. How can I best use the WRT160N to improve signal quality and network performance?
2. Depending on the answer to #1, how do I force the gaming systems to communicate directly with the E3200 (my assumption due to the performance) rather than the WRT160N?
I'm sure there will be more questions, but let's start with this. I appreciate any feedback anyone can provide.
Thanks,
Phil

1. You are going to have to use a cable between the two routers.
Go here... to connect two routers.
2. Assuming wireless connections just make two different SSID's between the two routers and connect to that specific SSID.

Oracle 11g - Network Configuration check

Hi All,
This is my first time here and I am a newbie to Linux and Oracle installation.
I just finished installing Linux Enterprise version 5 ( provided by Oracle corp).
At the time of installation I did not do any type of network configuration and let the default network connection take effect.
After installing all the pre requirements for the Oracle 11g installation on my laptop I was stopped with a warning on the Oracle univesal Installer - product specific Prerequisite check.
This is what it gave me---
Checking Network Configuration requirements..
Check complete. The overall results of this check is : Not executed <<<
Recomendation : Oracle supports installation on systems with DHCP-assigned public IP addresses. However the primary network interface on the system should be configured with a Static IP Address in order for the oracle to function properly.See the installation guide for more details on installing the software on systems configured with DHCP.
I checked with the manuals and do not find any information about how to fix it.
The info given in the manual is
Installing on DHCP Computers
Dynamic Host Configuration Protocol (DHCP) assigns dynamic IP addresses on a network. Dynamic addressing enables a computer to have a different IP address each time it connects to the network. In some cases, the IP address can change while the computer is still connected. You can have a mixture of static and dynamic IP addressing in a DHCP system.
In a DHCP setup, the software tracks IP addresses, which simplifies network administration. This lets you add a new computer to the network without having to manually assign that computer a unique IP address.
Now i made some changes to the Network Config as root user and my Network configuration file looks like ( ie. /etc/hosts)
127.0.0.1 localhost StaticIP
It was previously something like
127.0.0.1 localhost.localdomain localhost.
As per the installation documents where ever i had references to localhost, i had left the localhost with the same name ' localhost' and have not changed it. Now it has StaticIP and I am not sure how to proceed.
What must I do?
I want to fix this error and also want oracle to work.
Thanks for your help!!

Thanks a lot guys to respond to this. I am using OEL5 ( supplied by Oracle Corp) and Oracle 11g. Installation of Linux takes about 40 minutes and installation of Oracle takes about an hour to 2 hours. Not sure why some RPM's do not show up on the CD's provided by Oracle.
So I tried to reinstall Linux . But the whole problem is, the Network Screens ( during installation) do not show up at all. It just skips that portion and goes to the Screen where there is the world Map and tells you to set up the time and date. I tried installing Linux many times and those Network configuration screens do not show up at all.
Here is my dilemma. After installing Oracle 11g, and immediately accessing the site https://localhost.localdomain:1158/em takes me into the OEM.
But after I shut down my machine and boot up again, I am unable to use the OEM's site https://localhost.localdomain:1158/em. Instead I get the message
===============================
Unable to Connect
Firefox can't establish a connection to the server at localhost.localdomain:1158
1. The site could be temporaily unavailable
2. If you are unable to load any pages, check your computer's network connection
3. If your computer is protected by firewall or proxy, make sure that firefox is permitted to access the Web.
===================================
I am thinking the problem is with 2. I do not have any firewall in my machine and i have also disbaled SELINUX.
I want to configure the computer so i can use the OEM in my Linux laptop.
My $ cat /etc/hosts gives
127.0.0.1 localhost.localdomain.
Please help me setup the Network so i can connect to 11g OEM.
And BTW this laptop is not even used to connect to the Internet.
Thanks

Optimize Hosts and Start Maintenance Mode Not working with warning (23756)

I have a new 2012 Hyper-V3 cluster, with SCVMM 2012 SP1.
Putting a Server into maintenance mode used to work, it would live migrate all the virtual servers off the host and pause in the cluster.
Also the new Optimise Host Feature also used to work.
Now all I get is this :-
Warning (23756)
Changes have been made which should be verified by running placement again.
Recommended Action
Use the Refresh Preview action to run placement again.
you can manually live migrate all the VM's of the host then put it into maintenance mode and all works fine !.
I do not understand what this "use the Refresh Preview Action" is. I cannot find any reference to this anywhere.
hope someone can help
many thanks
Mark Green

Hi Mark
Firstly, the error text for this event is wrong, which is why it has a confusing recommended action. This error indicates that while planning an evacuation, something unexpected occurred when reading the underlying hosts and VMs. It may be something
transient, in which case you can attempt to manually the VMs off the host, and then see if this error resolves itself.
If there is something more fundamentally wrong, you can find what the underlying error is by collecting traces. Search the traces for the error text, and you should see the underlying problem embedded in the trace right next to this error.
Details of how to collect traces: http://blogs.technet.com/b/chengw/archive/2008/05/08/how-to-collect-scvmm.traces.aspx
Apologies, this error is very confusing and does indicate an unanticipated problem in our product. We are working to improve this experience in future versions.
I hope this helps!

Remove VSA 5.1 but keep ESXi host network configurations

Hello,
I ran into problems with a 2-node vSphere 5.1 VSA Cluster not coming online after adding more hard disk and RAM to the physical ESXi hosts in the cluster. After talking with VMware Support for over 2 hours, we exported all of the virtual machine data and powered on the VMs running on just local storage on the ESXi hosts. Now I need to remove the broken VSA Cluster and deploy a new VSA Cluster without interrupting the production VMs now running on local storage.
I've looked at the cleanup.bat file, but am concerned about it resetting the network configurations on each of my hosts back to "greenfield" configurations at which time the VMs would all lose network connectivity.
Can the VSA Cluster be manually removed without causing an outage on the VMs? If so, where can I find those procedures?
Thanks!

Hi
Google for the following Subject "[Internal] Manual permanent destructive removal of a VSA cluster (2086522)"
Following this Article I removed an VSA-Cluster and did a brownfield Installation with Networksettings all be there.

Networking between host and qemu imag for telnet

Hello.
I want to start doing test and learning a bit about networking.
But I only have a computer, and it doesn't have even hardware emulation, making the use of any modern distro as a virtual machine painfuly slow.
So I downloaded a floppy distro.. and I manage to get a virtual network card working. But there is no ping between host and guest. I can't Telnet neither, of course.
Qemu man page and google are confusing me a lot. It speack of redirecting ports.. no solution to that
I don t have firewall, as I don't have Internet at home.
What can i do now? :S
Thanks in advance

I think I must stop drinking so much cofee on the afternoon, lol
Thank you very much for adding my reply!

Obviously, you did inadvertently use the "Report" button to submit this.
But don't worry, this happens quite often.
I tough a bit about the problem, and followed the steps on the Gentoo Wiki for sharing a conection between two guests, and I found the same problem, but with the vbe module being unabaible. After a bit of rage, I realized two possible workarounds:
First thing, is that I compile my kernel. As I don't have KVM or Hardware emulation, I just don't compile any virtual machine module, to save memory. BUT, I do have the /dev/net/tun device who qemu can't recognice (yes, I tried to run qemu as root), so It seems that it is compiled after all
The second thing, is that I also stripped the daemons and services at bootup, as I don't have Internet, or othercomputers, I don't need most of them. Between the services I don't start at bootup is the netwprk daemon... but if i try to start it, all it does is delay the bootup for almost 2 minutes looking for a network :S
So, I'll just copy my /etc/rc.conf, where I just did the changes of the wiki. Maybe I did something wrong, maybe I lack something.

Change/Configure Host and Port for the Web Service Proxy with Server

Hi,
Is there a way to configure Host and Port in generated proxy for Web service depending upon server. (ADF 11g)
Scenario:
We are consuming Credit Card web service from a service provider and have different Host and Port details for development, QA and Prod.
So we created proxy classes using wsdl for development and things work fine, but when deploying code to QA or Prod we need to change the Host
and Port details.
Is their a way we could user variable's for Host and Port which looks to some configuration file to evaluate their values
based on server.
I am a bit new to this web service .. will appreciate if someone could provide an example.
Thanks.

Are you using Web Service Proxy or Web Service Data Control?
If you are using Web Service Proxy. Right click on your Proxy --> Properties --> Port Endpoints. Here you can change the IP & Port details for each port.

Officejet 6000: Network Configuration Page prints over and over

When this printer runs low (NOT out!) of ink, it begins printing the "HP Network Configuration Page" over and over and over. Installing a new cartridge seems to solve the problem, but I'd rather empty the one that's in there before throwing it away in favor of a new one and wasting paper in the process. I'd appreciate some help.

Hello vancat,
You need to place the alignment page that is printed on the scanner glass and then press the Scan button. This will complete the alignment process.

Configuring host and remote trading partners

Hi,
Being new to B2B, I have a very basic doubt.
I have two machines, one which I am using as the host trading partner and the other the remote trading partner. Would the steps involved in configuring the host trading partner be the same as the ones required to configure the remote trading partner?
Currently at the host trading partner end, besides creating the Identifiers for the host trading partner, I am also
1. creating the remote trading partner
2.creating the identifiers for the remote trading partner
3.assigning the documents to the remote trading partner and
4.creating the delivery channel for the remote trading partner.
I assume I would have to do a similar configuration at the remote trading partner end, before creating the agreements for the trading partners.
Is there anything else that would need to be handled?
It would be great if someone can share the stepwise instructions that would be needed to configure host and remote trading partner. I am using Oracle B2B 11g and have not worked with the previous versions of B2B.
Any help in this direction will be greatly appreciated.
Thanks
Priya.

Hi Priya,
Steps are correct and you have to configure both the machines.
You can refer B2B samples available as part of SOA Samples in below link:

Why does my printer randomly cycle and print a network configuration page?

My HP Photosmart C4795 randomly cycles like it is cleaning the printer heads. Sometimes it is hours between this cycling. Sometimes it will print a network configuration page without being requested.
There are 3 computers connected wirelessly. Both run Windows 7. The wireless signal has a very good signal - the router is ~12 ft from the printer.

It could be a power issue. If the power fluctated the printer would restart which might cause it to do a dirty power print clean.
If you have a surge supressor I would try that.
Not sure why the network config page would print with a power surge, but another possibility is a friendly neighbor playing with you by sending printer clean reauests and network config print jobs. :-)
Please mark the post that solves your problem as "Accepted Solution"
Sometimes it takes several posts back and forth to get to a solution - please be patient.
