• 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.

• Mac flooding attack, unicast and sniffer

  Hi all

  happy new year to all members of support forums!

  If I am not mistaken in a switched environment a crowd will see all unicast (addressed directly to her), broadcast (in the same VLAN) and multicast frames (when membership in the multicast group).

  Now consider that I run a MAC flooding attack on the switch in question. It fills the entire MAC table (8,000, 16,000 entries, no matter). Now, host A wants to connect to B (both on the same switch, same VLAN). Host A has the host host b MAC address in its arp table. A sends the packet, it happens on the switch (he learn not the port that the host is turned on, because the cam table is full), but he'll find no MAC address of host B as well (I know, it may be present, but assume that it is not). So because the host has the MAC address of host B I know more of that host A sends a unicast frame on. So the switch inspects its CAM table looking for MAC of host B and "said" I don't know where host B is, so let me send the frame / packet to all ports. Even if he she will send to all ports, it's still a unicast. Now, my question is (if all the foregoing is correct). When I run a sniffer on host c (connected to the same switch, even VLAN) will be able to see the package? Or do I have to activate the "Promiscuous" inside Wireshark mode?

  Thank you in advance!

  Hi Adam,.

  But in the case of broadcast frames each host on the same VLAN saw, correct? Or should I always turn the promisc mode?

  I guess you always ask the subject of sniffing and Wireshark. In this case, diffusion frames would be visible in Wireshark whatever the promisc mode setting.

  So the frame comes with mac dest FF:FF:FF:FF:FF value and each host leans on the chassis, then the network layer and all hosts (but not the one with the IP address in question) drop the fames / package. OK, so I guess I'd still have active promisc

  What you have described is a product of correct treatment of a broadcast frame including its load by the driver for the CARD and the driver of the intellectual property. However, Wireshark works at a fairly low level: it binds relatively close to the driver for the CARD. Each image that is received by a NETWORK card and handed over to the operating system for further processing is also copied in Wireshark. So even if the IP driver can know that the IP packet is for someone else, and he falls, Wireshark will nevertheless show the frame. The trick is in getting the NETWORK adapter to accept the framework in the first place. If the framework is to broadcast, the NETWORK adapter will accept it automatically. If the setting is unicast/multicast and you still want your NIC to accept it even if it is not planned for this particular NETWORK interface card, you must use promisc mode.

  Please feel welcome to ask for more!

• 3702 AP loss connectivity to WLC in local mode

  Hi Experts,

  I have an AP 3702 which loses connectivity to the WLC and line protocol goes down.

  PoE is always present on the connection to the switch, but only to 15.4 instead of the full 16.8 as with normal operation 3702.

  There are 8 other 3702 AP this floor who have no problem.

  "Could arp not the ip address of the controller, try again later" is a common phenomenon in their newspapers so I don't think it has any bearing on the issue with this particular access point.

  All 9 x 3702 are connected to a switch of edge double accommodation 3750 X battery via 3 x 3560CX in the ceilings.

  If I close and (after some time) put to the port of the switch, the AP will get back in touch with the WLC, but then drop again as before in an hour or two.

  I deleted the config on the AP and let it sit in mode monitor/sniffer for a few days and he stayed until perfectly so I thought everything was ok. I've reconfigured to accept clients, and since then, it has dropped again.

  Hope that this is not a hardware failure and your advice is really appreciated.

  Thank you

  Messages above give me the feeling that there is a problem with communication between the physical network of the access point connection and control software. This can be hardware and associated software. Your best bet to analyze tracing messages is TAC, so my advice is to connect a case and let send them your registration. The 3700's have "limited lifetime warranty" so you can ask a new in case it is broken (even without a smartnet) you have to wait at least 10 days. Keep us informed about the solution!

• ACS 5.1 - command line filters does not not in Config Mode

  Hello

  I am trying to set up filters to deny command line sniffer commands being entered. I have set up a command set and applied to an authorization policy. The command filter works great for commands in privileged mode. However, the filter does not work for any order that is entered in configuration mode.

  I have a set of commands that will deny for a test installation:

  display the clock

  terminal length

  display monitor

  duration of the distance

  the monitor session

  The first three commands are entered from the initial mode of privilege and they are omitted by the AEC. The last two commands can be entered in config mode and the ACS does not stop their entry.

  I have attached two screenshots that show configuration commands on GBA game and a Terminal session which commands are filtered and which are rented by the intermediary.

  Has anyone encountered this problem? Is there something else I should be adding to the command Set? Is this a bug?

  There is a bug on the Cisco site that relates to the command filters:

  http://Tools.Cisco.com/support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCtf08567

  I don't know if this bug applies to this question because there is so little information on this subject. In addition, if it does not I don't understand workaround to apply it to this situation.

  Any advice would be greatly appreciated. -(ACS Version 5.1.0.44.2)

• IPsec VPN between two routers - mode ESP Transport and Tunnel mode

  Hi experts,

  I have this question about the Transport mode and Tunnel mode for awhile.

  Based on my understanding of 'Transport' mode is not possible because you always original "internal" private in the IP headers or IP addresses. They are always different as public IP on interfaces enabled with Crypto Card addresses. When encapsulated in the VPN tunnel, the internal IP addresses must be included or the remote VPN router won't know where to forward the packet.

  To test, I built a simple GNS3 with three routers laboratory. R1 and R3 are configured as VPN routers and the R2 must simulate Internet.

  My configs are also very basic. The R2 is routing between 1.1.1.0/24 and 2.2.2.0/24. It is defined as the gateway of R1 and R3.

  R1:

  crypto ISAKMP policy 100
  BA aes
  preshared authentication
  Group 2
  ISAKMP crypto key 123456 address 2.2.2.2
  !
  Crypto ipsec transform-set ESP_null null esp esp-sha-hmac
  !
  10 map ipsec-isakmp crypto map
  defined peer 2.2.2.2
  transformation-ESP_null game
  match address VPN

  !

  list of IP - VPN access scope
  ip permit 192.168.1.0 0.0.0.255 10.0.0.0 0.0.0.255
  !

  R3:

  crypto ISAKMP policy 100
  BA aes
  preshared authentication
  Group 2
  ISAKMP crypto key 123456 address 1.1.1.2
  !
  !
  Crypto ipsec transform-set ESP_null null esp esp-sha-hmac
  !
  10 map ipsec-isakmp crypto map
  defined peer 1.1.1.2
  transformation-ESP_null game
  match address VPN

  !

  list of IP - VPN access scope
  Licensing ip 10.0.0.0 0.0.0.255 192.168.1.0 0.0.0.255

  I configured transform-"null" value, while it will not encrypt the traffic.

  Then I tried the two 'transport' mode and mode "tunnel". I ping a host in the internal network of the R1 to another host in the internal network of the R3. I also tried 'telnet'. I also captured packets and carefully compared in both modes.

  Packets encapsulated in exactly the same way!

  It's just SPI + sequence No. + + padding

  I will attach my screenshots here for you guys to analyze it. I would be grateful for any explanation. I confused maybe just when it comes to the NAT...

  I guess my next step is to check if the two modes to make the difference when the GRE is used.

  Thank you

  Difan

  Hi Difan,

  As you point out the mode of transport is not always applicable (i.e. applicable if IP source and destination is equal to corresnpoding proxy IDs).

  A typical scenario in this mode of transport is used:

  -Encryption between two hosts

  -GRE tunnels

  -L2TP over IPsec

  Even if you set "transport mode" this does not mean that it will be used. IOS routers and I blieve also ASA will perform backup even if the mode of transport is configured but does not apply in tunnel mode.

  I can take a look at your traces to sniff, but all first can you please check if you transport mode on your ipsec security associations? "See the crypto ipsec his" exit you will show the tunnel or transport mode.

  HTH,

• Preview.app stuck on the first page of the PDF in single page mode

  I regularly Preview.app view PDF files and want to use the "Single Page" function to display an entire page at one time. I have 'Single Page' display set as the default behavior.

  Lately when I open a PDF file, they properly open the first page, but I am unable to navigate to another page via the drop-down page, touch up/down arrow. If the PDF file has a table of contents, I am able to go beyond the first page through it and then proceed to navigate normally. If it is not a table of contents, the only solution is to continuous scrolling mode and continue to navigate beyond the first page.

  It's very annoying! Unfortunately, I can't remember where this started happening. It could be when I upgraded to MacOS Sierra, but I can't confirm.

  Everyone else see this behavior?

  Hold down the Option/ALT key, then use the cursor to the TOP or to the BOTTOM of the key.

• Absent portrait mode on iPhone 7plus?

  all the hype online for 'portrait' mode has been one of the main reasons that I opted for the more 7...

  However, the phone doesn't have this mode! Yes I use the latest version of iOS.

  I checked phones in the Apple Store and they did not either portrait mode.

  IT seems that they only in the States and not the Canada. Is there a reason for this?

  Can't find an answer anywhere as if nobody noticed?

  Help!

  Hello

  Portrait mode will be made available for iPhone 7 more users via a free software upgrade, later this year.

  This has not yet been published anywhere as a public release.

• Portrait mode on iPhone 7 +.

  Received my new 7 + yesterday and tried to find a way to take those portrait photos when the background is blurry.

  I found some tutorials and it just says to drag in portrait mode. My phone/camera doesn't have this option. I have the latest iOS update. Is there something that I need to activate?

  You are referring to the effect of depth of field.  This effect will be available with iOS 10.1, which is currently not quite yet.

• Activate App stuck on waiting and power Mode low does ' t

  Hi all

  I have at least two concurrent problems with my iPhone 6 + iOS 10.0.2 (but started with iOS 9).

  I can't install new application directly from the App Store on the phone because they were stuck in the phase of "pending". Same behavior of update of the applications that are already installed.

  The only way to update/install the app's iTunes download and synchronize.

  The other simultaneous problem is in what regards the activation of "low power mode" with the rocker switch (settings > farm > Low Power). Whenever I try to activate (manual or automatic 20% of battery) function, the gray toggle becoming in the Middle, then return to the OFF position.

  I already have backupped & restored several times, but nothing has changed.

  How can I solve this?

  Thank your

  Best regards

  Hello Axoduss,

  Thanks for posting in the communities of Support from Apple. I see that you have two problems. One is that the low power Mode is not activated, and the other is that updates and new applications are blocked pending. I know that I rely on my iPhone for everything. It is important to ensure that it works as expected. I'll be more than happy to help.

  Great job to the backup of your phone and restore. It's a great way to help solve these issues.

  If you are restoring from a backup, the problem may be in the back upward. I recommend to reset the phone to factory settings and set up like new to see if the Mode low power and installing apps works. If this does not work after the installation in the new and not after the restoration then you want to restore your data manually and not market back. Here is an article on setting up the phone as new:

  Let us know if that helps.

  Take care!

• After Malware that my login is disabled cannot start in safe mode

  Hi if anyone can help.

  A friend tried to watch movies online, I'm not sure of the site they visited, but were asked to install MacKeeper and I believe that they did, as I noticed it was to download and installed the following day and I asked them why they did this and they said it was the only way to watch movies!

  Anyway to cut a long story short my friend then called me to say they received a "pop" window to say that my computer has a virus and call a number of 1800... I told them to do nothing certainly not call the number and I would like to sort.

  So basically since then that then I can not connect to my main account at the start, the section where you type your password won't let me type into it and there is a symbol of the brand of 'question' next to it. If I hold my mouse over the question mark I get a dialog box stating "Please enter your password to iCloud as... as well as the date. I can only login as a guest and I cannot connect in 'safe' mode by holding down the SHIFT key.

  I deleted the MacKeeper Application (and also another OS player application that is newly installed the same day!) and empty the memory cache of my browsers and also now upgraded to 10.11.6

  I also run disk utilities, but still I'm getting this problem trying to connect to my main user account!

  I think that it is some kind of malware, does anyone have ideas how to solve at least the connection problem?

  If I could stamp out to see if there is any malware stuff going on behind the scenes it would be too great!

  All suggestions welcome.

  Thanks, Ciaran

  

  How did you uninstall the MacKeeper application? Please be as specific as possible, unless you have followed the steps, I suspect that your system has installed to uninstall. If this is the case then you will need to re-install and uninstall immediately by following the instructions of developers. Otherwise, the best thing to do is to do a wipe and installing OS X and then manually install your applications and restore your data from your Time Machine backup.

  I'm sure you probably learned to not let this 'friend' enter the 100' of your computer.

  I upgraded from Capitan in Sierra and got the problem that after I pressed the power button, the screen is full white. This problem has occurred on the Sierra, never happened in Capitan.

  I went to the Apple store today, they made a few diagnostic and found no problem. Everything is good. System is fine too. In the Apple store, they showed me to press SHIFT after I press the power button and it will start up the Mac in safe mode. They told me this can sometimes help fixing the boot issue. My Mac actually works very well in the Apple store. I tried the power and turned off twice in the store, and there is no problem. I am happy and come home.

  After I go home, I turn on my Mac, it always has the same problem before you go to the Apple store, after I pressed the power button, the screen is completely blank. So I tried to boot mode safe by pressing Shift and taking until I saw the Apple logo on the screen.

  After I log in, I checked my Mac mode, this is actually Normal mode!

  If I intended to power to the top of my Mac in safe mode but it turns out to be normal.

  If I do not press SHIFT and hold it pressed down after I turn on the power, I'll have just a white screen!

  It works very well in Apple store, but not in my own House.

  Anyone know what is happening?

  What is different between your system and the store? Have you taken your own keyboard & they were they that? If you use a bluetooth keyboard try using a wired USB one instead. Is this an original Apple keyboard?

  Do you have other devices connected? If you delete them.

  Please see the article below from Apple, it has information about starting in safe mode without keyboard (by setting a NVRAM variable). If you enter a work boot, you can put the mini in safe mode from there, via the command appears on this page...
