• Intel 82579LM NIC on the Portege R830 does "Promiscuous" mode?

  Hello

  I have a laptop (Portege R830) work, who does not want to sniff the packets. I connected to a hub Netgear DS104-, as well as an older laptop and then uplink to ADSL.

  Run a continuous ping the default gateway and Wireshark on the devices and the other computer can see the pings from Toshiba, but not vice versa.

  The Toshiba runs under an administrator account has disabled Windows Firewall and my disabled Symantec endpoint encryption. I don't have any other AV to my knowledge.

  Does anyone have ideas of services I should turn on or off, or the knowledge of the characteristics of this NETWORK adapter?

  According to the Intel site "Yes, all cards Intel® PRO/100 Intel® PRO/1000, Intel® Gigabit, Intel® PRO/10 Gigabit and 10 Gigabit from Intel® currently on the market support"Promiscuous"mode." But Intel® 82579 Gigabit Ethernet Controller is not in the list that follows http://www.Intel.com/support/Network/SB/CS-004185.htm?wapkw=%28promiscuous%29

  Thanks for your time.

  Usually the firewall or security software Internet blocks pings so maybe try to uninstall Symantec completely. Disable it just cannot turn off everything.

  Another thing to try, is to use a static IP instead of DHCP. Disable IPv6 or install a new LAN driver from the Intel Web site may also help.

• JOINT configuration in promiscuous mode?

  Hello

  I have two switch catalyst 6500 in VSS each with a JOINT module, I want to monitor four VLANS three of them is VLAN users and one of the servers, I'm planning use VACL to capture traffic.

  My first question is how to configure the data ports of JOINT in promiscuous mode, if in the configuration guide say that by default data ports are "Promiscuous" mode, which means that I can't do any configuration in the ports of JOINT data?

  Second, if I have two switches 6500 in vss each with a JOINT module, I need to examine other configurations of this situation?

  The VACL I'll put is:

  ACL_IPS extended IP access list

  allow an ip

  !

  VLAN-access plan VACL_IPS 10

  corresponds to the IP ACL_IPS

  action forward

  !

  VLAN filter VACL_IPS vlan-list of 30, 40, 50, 100

  !

  detection of intrusion switch 1 module 4-port data 1 capture allowed - vlan 30,40,50,100

  switch 1 capture of data-port 1 intrusion detection module 4

  1 switch intrusion detection module 4 data ports 1 autostate include

  !

  detection of intrusion switch 2 module 4-port data 1 capture allowed - vlan 30,40,50,100

  switch 2 capture of data-port 1 intrusion detection module 4

  2 switch intrusion detection module 4 data ports 1 autostate include

  Thanks for the help.

  The METHOD didn't need special orders to inspect the traffic in Promiscious mode.

  You'll want to put your JOINT management on a local VIRTUAL network interfaces to talk with them:

  detection of intrusion management access module 4-port - vlan 99

  Use the switch "transfer the capture:

  VLAN-access plan VACL_IPS 10

  corresponds to the IP ACL_IPS

  action before capture

  Get rid of the spaces between your numbers VLAN

  VLAN filter VACL_IPS vlan-list 30,40,50,100

  If you put two IDSMs in the same chassis, you will need to decide how to divide traffic between them. You can assign different VLAN to each METHOD.

• VMWare ESXi 5.1 promiscuous mode.

  Hello

  I installed VMWare ESX5.1 and I created several machines virtual v.7 on it.

  All virtual machines are same vSwitch and the Group of ports that are configured to reject the promiscuous mode.

  The problem is that if I dump the traffic from the vMachines I CAT see ANY traffic is originating and destined to other virtual machines.

  I used tcpdump to dump the traffic like this:

  tcpdump-i eth1 hosts not < my_laptop_ip >

  And I see stuff like this:

  IP 16:03:45.386981 192.168.19.108.http > 2.194.11.124.51972: P 40724:41157 (433) ack 1189 win 175

  192.168.19.108 is the IP address of another machine in the same ESX.

  Is this normal?

  Thanks in advance

  The destination is a layer 2 multicast MAC, entirely explains why the other machines virtual in this VLAN see all outbound traffic that is routed on this router. Note that you should not see any incoming frames from the router, as destination of these frameworks MAC would be the unicast MAC of the respective virtual machines.

  Also, the physical host on your network computers would see all this traffic like VMs unless your firewall send reports of IGMP Membership and you have IGMP snooping enabled on your layer 2 switches.

  So the behavior you're seeing basically is "perfectly normal", side vSwitch/layer 2.

  That being said, mind telling us what kind of firewall or clustering do you use? What is some active firewall cluster that requires multicast? In all cases, the vendor 01-00-5e ID matches IPv4 multicast addresses. You seriously use a multicast IP (for example 224.x.x.x) as your default gateway in this subnet? I'm pretty sure that's not how things are meant to work in the world of IPv4.

• Workstation 10 on Windows 7 Prof - "Promiscuous" mode?

  Guys, after reviewing the documentation, I may get it wrong, but it seems to be no option to run vSwitches in "Promiscuous" mode as there is in ESXi?

  A context here. I am under a Linux of Kali (pentest box) to test different OS (Windows and Linux) and analysis of newspaper with a box of SIEM (ArcSight logger).

  One of the streams in the SIEM is an IDS (Snort), which obviously doesn't help if the vSwitch is in its normal operating mode. I can change it to a configuration line and fire all through it, but don't want to go there.

  The guide 10 Workstation seems to say I turn on "Promiscuous" mode if it is installed on a Linux host and, by omission, seems to imply that you can't do it on a Windows host.

  I read it wrong?

  There are a few parameters that you can use - took notes - see http://sanbarrow.com/vmx/vmx-network-advanced.html keep in mind that on workstation "vmnet" don't are not really switches - look at them like turntables. On a modern Win7 or later, you may need additional measures to make sure that you really get Supreme mode - check the firewalls, Antivirus, so locking tools. WS running as the administrator may require. It may be useful to use a bridged VMnet which is not used by the windows host at all - only assing vmware-bridge-Protocol to the network adapter and then - remove IP4 and IP6, and other protocols

• VSphere - "Promiscuous" Mode?

  I have a virtual machine that is running in Vsphere Hypervisor.   I'm trying to install a VPN (SoftEther) utility that requires the network adapter that will be put into Promiscuous mode. After reviewing the documentation ESXI, he tells me to go to the 'Configuration' tab, but this tab is missing.

  Is it possible for me to configure my NIC as such? I called tech support and they told me here.

  I was able to download the command line tool (esxcli) and that allowed me to set promiscuous mode. It is not trivial to understand this point, but at least I got around him. For anyone else running into this problem, you can do something like this:

  To list the interfaces /ports

  esxcli - Server IPADDRESS - USER - network interface ip PASSWORD password username list

  My switch was vSwitch0 after running this.

  To check policy:

  esxcli - Server IPADDRESS - username USER - password PASSWORD policy standard vswitch network security get vSwitch0 - v

  To set the policy:

  esxcli - Server IPADDRESS - USER - password PASSWORD standard vswitch network username policy security set f m true - false true Pei - v vSwitch0

• Why do I need "Promiscuous" Mode when you use multiple vSwitches and a bridge?

  Hello guys,.

  5.5 ESXi running.

  I created two vSwitches and putting multiple virtual machines in each vSwitch. I have a CentOS VM with two network cards, one in each vSwitch. I configured the CentOS VM to work as a bridge. I could spend between devices on a vSwitch pings, but ping has no devices on a vSwitch devices on the other (through the CentOS acting as a bridge). The ARP requests have been sent across the bridge, but have never had sent answers ARP. I checked around online and someone recommended to enable Promiscuous Mode. I activated the Promiscuous Mode (changing to refuse to accept) on the two vSwitches (which is then applied to the change to all virtual machines). You can read more about that here: VMware KB: how "Promiscuous" mode operates on the virtual level switch and portgroup

  Now all of a sudden, everything works.

  My question is: why?

  I think that I don't want to Promiscuous Mode unless it must be such that it will result in more traffic to each VM it had reached before. I don't really understand why I need to authorize this change, and any help would be nice!

  Without promiscuous mode, vSwitch and port group will only transmit traffic VMs (MAC addresses) that are directly related to the port groups, he will not learn the MAC addresses that, in your case, are the other side of the bridge. The "Promiscuous" mode, all traffic is sent to each virtual machine on the vSwitch and port group and it's virtual machine to decide what to do with the network packets. As you have already mentioned, this isn't a parameter that you want to apply to a large number of virtual machines. For this reason, you can create a second group of ports on the vSwitch with only of CentOS virtual machine and activate the "Promiscuous" mode on only this group port rather than the vSwitch.

  Hi Keeperparma,

  There is no option in Acrobat reader to customize playback mode when you start the player, but you can configure for a specific file by using the "view original" feature of acrobat, but which apply only to this specific pdf.

• VMs and vswitches shared using the "Promiscuous" mode

  We are in the middle of setting up our new VM environment and you want to include Symantec Web Gateway virtual appliance. Must the vswitches (vNIC) use promiscuous mode. The problem is that all of my physical network cards are distributed between 4 virtual switches. No other virtual machines require promiscuous mode. When you set this mode on a vswitch, how will this affect the other virtual machines using the same switch? "Promiscuous" mode can be set on the switch and only ebabled to the virtual machine?

  I'm under esxi 5 and 8 network adapters in the servers of my host. There are 4 configured vswitches, one for management, data traffic, one for vmotion traffic and one for our DMZ.

  Thanks in advance

  You can create a separate virtual machine for this virtual machine port group and set security for the virtual machine portgroup activating the mode of promiscous-only activate the promiscous for virtual machines will be connected to the VM Port Group

• Activate the Promiscuous Mode on a vswitch

  I'm creating a new virtual machine... Cisco 3300 ISE. In the instructions, he told me to make sure that "Promiscuous" mode on the vswitch. If I enable this, will it screw up one of my other virtual machines that are currently using this option? I am using vCenter 5.0 with ESXi 4.1

  Thank you

  No, it shouldn't - you can also create a separate virtual machine port group and just activate for this group of port promiscous mode and not put overall vswitch

• Operating system of the virtual machine attempted to activate the adapter Ethernet0 promiscuous mode. This is not allowed for security reasons.

  Hi all

  When I start my vm I get error

  I have been to this page http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 287

  From this page, on my webhost, I created a group called "vmware-vmnet0", then I add the user running vmware to this group.  I can give this rw on/dev/vmnet0 group permissions

  However, I still get the same error above on starting the virtual machine each time.  How can I solve this terrible problem.

  Device nodes are re-created at boot time.  You can thank Linux udev.  To work around this problem, create the vmnet devices * with the ownership and the permissions you want under/lib/udev/devices.

• Re: Satellite A300 GN1 hhd PIO mode by default... problem need to DMA

  Sorry for the bad English

  Wait a minute: you use Vista and Windows XP Home edition or you installed Vista only? I didn't understand exactly what you wrote.

  If you are using Vista just go to BIOS settings and set SATA controller in AHCI mode. After restarting Vista several AHCI drivers will be installed and Vista work well will win.
  If you use two operating systems, it can be problematic, because you can not set on AHCI back. You will get the blue screen after each start up Windows XP Home edition.
