How to Set HyperV NIC in Promiscuous Mode
Is there any way to set up a NIC on a virtual HyperV guest in promiscuous mode?
I want to try and run a web filtering product on a VM. Wireshark does not indicate that it is capturing all traffic.
I have my switch port mirrored already and it works with a regular box but not with the VM.
Any help would be appreciated.
Thanks,
AndyI was able to make wireshark capture all the packets.
I followed this post:
http://fixmyitsystem.com/2013/08/Remote-Wireshark.html
The only diference is that use and Internal Virtual Network to connect from the
guest to the host.
My hyper-v host IP, for this network is 169.254.107.1 (check yours by doing ipconfig)
and the Guest is 169.254.107.20
Steps:
- Just get rpcapd (http://nmap.org/dist/nmap-6.40-win32.zip).
- Unzip it and install it on the hyper-v host
Open PowerShell
Enter-pssession Coremachine
Silently install: winpcap-nmap-4.02.exe /S
- Next up you will have to create a firewall exception for
this to be reachable from the management machine.
netsh advfirewall firewall add rule name="Remote WinPcap" dir=in action=allow protocol=TCP localport=any remoteip=169.254.107.20
(to turn on the rule) netsh advfirewall firewall set rule name="Remote WinPcap" new enable=yes
(to turn off the rule) netsh advfirewall firewall set rule name="Remote WinPcap" new enable=no
- Navigate to C:\Program Files\WinPcap
To start to packet capture service use
.\rpcapd.exe -p 2002 -n
- Get the GUID of the network card you want to use in WireShark
wmic nic where PhysicalAdapter="TRUE" get Description,GUID,MACAddress,Name,NetConnectionID
- on wireshark
Select Capture Options
Click Manage Interfaces
Select Local Interfaces tab and check the Hide box next to all of them
Select remote Interfaces tab
Click add button
For the host specify the hostname or IP Address
(I use an internal network to conect to the host)
My host IP is 169.254.107.1 and the Guest is 169.254.107.20
The port default is 2002 (set with the -p switch earlier)
Null authentication as set with the -n switch earlier
OK
You should now see a number of interfaces added
Click Close
- There will be a buffer size warning but it can be ignored, and hey presto,
you are capturing packets from a remote non GUI machine.
The process from here on in is the same as you would use WireShark with
local traffic capture. -
Hyper-V NIC in promiscuous mode
Hello,
Is there a way to setup a NIC in hyper-V or the Hyper-V virtual Swith to support promisuous mode for Web Filtering Software like websense?
Thank
ML~

Victor, what you've posted is a description on how to monitor one VM's traffic on another VM inside the same Hyper-V, but what is needed, is to monitor traffic from some physical PCs on a VM, for example:
There are machines A, B, and the Hyper-V host machine, all connected to the same physical switch, like HP Procurve or some Cisco device, etc. We can setup port mirroring on that switch (SPAN), so that all the traffic between A and B would be mirrored to
the Hyper-V host machine port, and we even can monitor that traffic on the Hyper-V host. But what is needed, is to pass that mirrored traffic, coming from outside of Hyper-V to a guest virtual machine. Is there any way of doing that using the Hyper-V settings
or some 3rd party switch extensions?

the physical ports the port mirroring. Windows Server 2012 R2 and capture driver
for my Hyper-V virtual switch extensions can be done through NDIS.
This can be enabled by the PowerShell, cmdlets are:
$a = Get-VMSystemSwitchExtensionPortFeature -FeatureId 776e0ba7-94a1-41c8-8f28-951f524251b5
$a.SettingData.MonitorMode = 2
add-VMSwitchExtensionPortFeature -ExternalPort -SwitchName name_of_the_switch -VMSwitchExtensionFeature $a
Wouldn't that difficult?
Related switch expansion port of the NDIS,
the identity of the captured driver,
unplug the monitor mode 2 (port monitoring)
and, in addition to the external port related functions.
This involves a process, the external port is connected to a physical switch occurred on the VM in the packet will be monitored.
Not a physical port setting, VM-to-be a part of it, for the time when, if you look at it, never to get a glimpse of the classroom.

I (
Alex A. Kibkalo )
was asked several times whether Hyper-V Configure Port Mirroring so that traffic from the physical interface on top of a virtual switch, the whole thing
went to the “LAN traffic mirroring” virtual machine for analysis. VMware is able do this, and Hyper-V Port Mirroring by default captures only traffic caught inside the
virtual switch-external traffic, of course, is not a particular VM, there simply is not.
While working in theMicrosoft
team, I had a conversation on the subject
Unfortunately, I do not remember with whom exactly :-(
The rare and is not documented. It was recently found a solution to this problem.
The following method works on nodes with Windows Server 2012 R2.
Windows Server 2012 update must be installed
2885541
So, you will need to Configure Port Mirroring Destination mode for the machine which will channel bandwidth.
For virtual switch is required to enable NDIS Capture.
As a traffic source configure the external port of the virtual switch with the help of PowerShell commands:
$a = Get-VMSystemSwitchExtensionPortFeature -Name “Ethernet Switch Port Security Settings”
$a.SettingData.MonitorMode = 2
add-VMSwitchExtensionPortFeature -ExternalPort –SwitchName v-switch_name -VMSwitchExtensionFeature $a
I would be glad, if somebody will help.

How to set up set which NIC card to use for multicast?..
I just downloaded Rolling Patch 1 for WLS6.0SP2.
While reading the README file it says
" ISSUE 42518: Provided a way to set which NIC card to use for multicast traffic
Can anyone tell me how to set this?. on my WebApplication server it has two NIC
cards and I want to use the NICcard which is being used to talk to internal network
for multicast messages.
One more thing,
Can anyone one tell how to search for bugs (ISSUES) in weblogic. I am looking
place where I enter ISSUE number and should get the detailed description of bug/issue
etc..
Thanks for helping,
Nilesh
Thanks Kumar, I'll try this.
Does this -Dweblogic.interfaceAddress used only for multicast. Or this is also
used to talk to AdminServer?.
The other problem I am facing is when I restart the AdminServer in recovery mode
it's not finding my WebApp servers, because my webapp servers are on public network
and my admin (management) server is on private network.
please look at http://newsgroups.bea.com/cgi-bin/dnewsweb?cmd=article&group=weblogic.developer.interest.management&item=1217&utag=
, for more details about my problem.
Thanks,
Nilesh

Apple TV is asking me to set network time. how to do this?
Apple TV is asking to set network time. How is this done?
Assuming this is not the first time you have used your Apple TV
You might try restarting the Apple TV by removing ALL the cables for 30 seconds.
Also try restarting the router.
If the problem persists, try a restore, you may want to try the previous procedures several times before doing this.
If this is a new Apple TV, it may also be that your network router is not allowing access to the timeserver, check that your router allows access over port 123. -
HT4262 How do I re-set my network access password?
How do I re-set my network password?
You simply set it via the airport utility.
https://discussions.apple.com/message/21138326#21138326
If you have forgotten the password, reset the Airport by doing a short press of the reset button.. this is called soft reset.. all passwords are set to factory for 5min so you can change them till your hearts content.. then upgrade the airport. -
My Wi-fi on/off button in setting has stopped working and I can't even attempt to find anything does anyone know how I can fix it?? I've already reset the phone setting, network and factory settings
can you see the wi-fi address in the about? if it show N/A, your iphone needs to be repaired.
if your ios is 5.1.1 or you can see the wi-fi address,you could try to connect your iphone to the itunes to restore and update. -

How to set network time
You can't set it manually, it requires access to the internet server in order to do so. It is currently having trouble connecting; make sure location is set correctly via settings, DNS should be set to automatic (settinga - general - network), ensure port 123 is open on your router. Router needs to be up to date, reboot ATV and router.

THe protected network name is gone and now my computer just shows me connected to "dlink"
How do I re-set it to the protected network? I tried to use a "wizard" i found on the net but it said the emulator wouldn't work and to go back to the CD. I have no idea where the CD isI got to the page but it did not seem to give me an option to do what I want. I could see how to reset the ROUTER ADMINISTRATION password (for which right now there is none) but there as nothing about setting up my network name and password, which was lost. Or is this the same thing as the router configuration password? (I was thinking that referred to a password that would allow me to change router settings)

I can not set network date, any clue?
Welcome to the Apple Community.
Assuming this is not the first time you have used your Apple TV
1. You might try restarting the Apple TV by removing ALL the cables for 30 seconds.
2. Also try restarting the router. (Also try removing it’s power cord for at least 30 seconds)
3. If the problem persists, try a restore, you may want to try the previous procedures several times before doing this.
4. If restoring from the Apple TV doesn't help, try restoring from iTunes using a USB cable.
If this is a new Apple TV, in addition to trying the above, it may also be that your network router is not allowing access to the timeserver, check that your router allows access over port 123. -
How to delete a PS network with status 'Technically Completed' (TECO)?
Dear all,
We have Webdynpro application, which will create a PS network in background. In the past it was working fine and many PS network are created. Now we have a scenario where some of the networks which are with status 'Technically Completed' (TECO) needs to be deleted from system. I tried to delete it from CJ20N, but it was not possible as the status is set to TECO. Please let me know how to delete a PS network which is with status 'Technically Completed' (TECO).
Thanks in advance.
Regards,
VijayThe cluster goes out and finds all networks that are available. This is an automatic process. As long as there is a network there, it will show it. If you don't want it to show, disable the interface and it will disappear.
. : | : . : | : . tim
Thanks a million Tim! Disabling the correct interface made it disappear!
Actually, I had disabled the interface before I started this thread. When you posted the suggestion, I went back and looked at the network connections again and found out that I had disabled the wrong interface! My bad!
However, here is the interesting thing:
After I disabled the NIC and it disappeared from the FCM I physically disconnected its cable (actually I disconnected all unused / unconfigured NICs) ....then I re-enabled it. Now I see that FCM does NOT pick it up again.
I think FCM picked up those NICs because at one time I had put that NIC in the production VLAN (from the switch side).
One observation:
If you have NICs in a HV machine which are not connected to a switch, they do NOT show up in FCM. Once you connect them to some network, they start showing up. I guess by connecting them to a network, they are able to see NICs in other HV nodes.
Take a look at this screenshot. I have 6 NICs in there which are disconnected, none show up in FCM

New to Mac...how do I get set up for wireless internet?
I've just been given a new Mac Book as a gift, and previously had a desktop windows computer that i used Comcast cable internet to connect to internet.
Can someone give me some pointers as to how I need to set up my internet now so I can be wireless? Can i still go through my comcast provider?
Thanks.a brody wrote:
Welcome to Apple Discussions!
Comcast typically does not provide a wireless solution in its own modem, but you can hook up a wireless router to their modem so your MacBook can be on wirelessly at your home. Comcast also usually gives you an ethernet modem, which most wireless routers support. If your Comcast modem is only ethernet and not WiFi, you'll need a WiFi router. Apple offers the Airport Express, Extreme, and Time Capsule wireless access points for easiest setup with the MacBook. The Express is the cheapest solution for someone with all WiFi capable machines in the house. If only the MacBook is present, you can also get a Time Capsule to be used with Mac OS X 10.5 if it is installed, to backup your Mac to a wireless hard drive, in addition to having wireless access. If you have a MacBook together with a machine with no WiFi card built-in, the Airport Extreme has LAN ports for any machine with a 10-base-T, 100-base-T, or Gigabit ethernet NIC card. Built-in to the MacBook is the ability to access the internet wirelessly at any WiFi hotspot on the road.
I've got an Comcast/RCA branded modem with both ethernet and USB connections.
Here's how to setup a wireless network at home with all of Apple's Airport base stations:
http://www.apple.com/support/airport/
Some third party 802.11n access points exist, but due to their being in draft specification, many won't give you full 802.11n access, and only give you 802.11g speeds unless their firmware is the same as Apple's.
Most are apparently operating off of the same draft spec. I'll just note that my D-Link D-615 notes an 802.11n connection with my late 2007 MacBook.
And "same firmware" seems to be a stretch in description. Firmware is specific to the hardware, so of course two different manufacturers are going to have different firmware - even if they are functionally compatible. Compatibility with various 802.11n draft or the eventual final standard should mean that the firmware is written to support the standard, with implied compatibility with other equipment designed to the same standard. -
The wifi has been lost or disconnected on my iPad. It's the iPad 2 and has not been updated yet. It's IOS 6.1.3 .. how do I add a network back onto it? I have typed in the name and chosen each of the securities and still hasn't connected!
Hey there Luba_kalstad,
It sounds like you are unable to join your network and cannot see it in the Wi-Fi list in Settings. I would try the troubleshooting outlined in this article named:
iOS: Troubleshooting Wi-Fi networks and connections
http://support.apple.com/kb/ts1398
Be sure you're in range of your Wi-Fi router (access point).
Tap Settings > Wi-Fi and turn Wi-Fi off and on. If your Wi-Fi setting is dimmed, follow these steps.
Confirm that your Wi-Fi router and cable or DSL modem are connected to power, turned on, and connected to the Internet. If not, refer to your network administrator or Internet service provider (ISP) for assistance.
Restart your iOS device.
Tap Settings > Wi-Fi and locate the Wi-Fi network to which you're connected.
Tap and Forget this Network.
Try to connect to your desired Wi-Fi network.
Note: You may need to enter your Wi-Fi password again if your network requires one.
Turn your Wi-Fi router off and on2. If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
Update your device to the latest version of software.
Update your Wi-Fi router to the latest firmware2. For AirPort Base Stations, install updates using the AirPort Utility.
And this section down toward the bottom if needed:
Unable to locate a Wi-Fi network
Verify that the network is available by tapping Settings > Wi-Fi and choosing from the available networks.Note: It may take a few seconds for the Wi-Fi network name to appear.
Move closer to your wireless router (access point) and attempt to locate the Wi-Fi network.
If you do not see the network you would like to join, you may be attempting to connect to a hidden network. Learn how to join a hidden network.
Supported Wi-Fi configurations vary by iOS device model. Find out which standards your device supports3.
Reset network settings by tapping Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings including:
previously connected Wi-Fi networks and passwords
recently used Bluetooth accessories
VPN and APN settings
Thank you for using Apple Support Communities.
Take care,

I have recently got a Time Capsule with my Macbook pro retina 15". I am trying to setup my time capsule as a wifi station at my home. But the thing is I can only access wifi from my lap only.
How can I share my network from timecapsule to other devices, and im using OS X 10.8.2
Please help me!
Thanks in advance!
(sorry for the bad english)How is the TC currently connected into the network?
It should work fine in bridge and create a wireless network.. it should already be able to share the network without being the main router.
Setting up wireless from wireless is difficult.
I would recommend you buy the USB to ethernet cable Apple sell as an accessory for Air and MBPr so you can actually use ethernet when required.
