• Reset TCP/IP v4 DNS guard!

  I want to set to automatically obtain DNS my TCP/IPv4 properties. However when I check the box it works for so long and then resets and seizes the addresses in the DNS address areas.

  How can I delete these addresses and get it to 'paste' in automatic mode?

  Thank you

  Try resetting TCP/IP: http://support.microsoft.com/kb/299357.  Make sure that you take note of the appropriate settings before doing this so that you can restore when it in fact.  This should remove all stored DNS addresses there and then they hopefullly will not be able to come back and you won't get them automatically.

  I hope this helps.

  Good luck!

• Reset TCP question

  I have a question about the TCP/IP communication. Let's say I have a device cisco running with off http server. If I send a TCP syn packet to the device with the port of destination 80/443(any non-listening port), the device responds by TCP RESET? Or it will simply fall package without any acknowledgement?

  I think it will be different from a device to:

  ASA will drop connection refused the services is not running, to do send reset use the command "resetoutside service" send reset to a TCP packet refused to the external interface.

  Default access points will reset

  Default routers will reset

  Default switches will reset

• Good method to reset the tcp connection after timeout error

  I have an application that I build that communicates with a Modbus TCP device.  If a communication occurs error I wish I could reset it TCP communication.  What I have is a control that raises an event when pushed.  In this case, I have a sequence that closes first the tcp connection and then opens a new connection.  My application starts and works very well.  To test the reset function, I removed the ethernet cable from the camera and waited until a timeout occurs.  I plugged the cable reset back to and pushed my control. Sometimes the reset will take place, but most of the time I'll get a timeout in the TCP vi open error.  After that, the only way I can establish communications must leave my application, disable and then enable the network device.  Then, when I restart my application I have communication with my camera.

  Any help would be appreciated on how I should be reset my TCP connection.

  Thank you

  Terry S of a. in writing:

  I've attached an example vi (LV10) that shows just the connection TCP and Reset.  An error occurs when you try to run the open in the event of reset tcp protocol.

  As writing that your code should be fine. There is nothing inherently wrong with it. However, depending on the device, you communicate with you can try to restore the connection too quickly once you have closed the connection. The device allows multiple connections to it and may require some time to clean up the things on his end after you close a connection. An experimental basis try wait little time between TCP and the TCP Open shut it down. If possible you can try using Wireshark to see what is happening on the network. It may be useful to diagnose what is happening.

• using tcp replacement reset interface

  Hi I'm new to cisco ips. can someone tell me pls the function to use the alternative interface for tcp reset.

  I have 2 interfaces for IP addresses. a command and control and other interface is an interface in promiscious mode.

  without this command the ID can send some tcp resets. or because it uses a different interface for tcp resets.

  can someone tell me pls.

  Under most of the facilities the tcp replacement reset interface is not necessary.

  By default the ports TCP resets will come back on the same interface where the attack was detected.

  So if your interface promiscuity is connected to a 100 Mbps for tracking hub then the tcp reset will be sent back this same interface promiscuitee in the hub.

  Or if your interface promiscuity is connected to the span switch port, the tcp reset will be sent back the same interface of promiscuity in that span port.

  The question becomes is the sensor can send reset tcp, but if the switch will accept them. Various switches will accept from the span port tcp resets. Some switches require only an extra parameter on the extended configuration to tell the switch to allow incoming packets to the span port.

  BUT there are some switches that do NOT allow incoming packets of their span ports.

  These ituations are the reason for the replacement tcp reset the configuration of the interface.

  Need 2 remote sensing interfaces (one for surveillance of promiscuity and the used the other as just replacing tcp reset interface). The port command and control NOT allow as the other tcp reset interface.

  Connect to the interface promiscuity to the scope of the switch port. You configure the second interface as the alternate tcp reset interface of the first interface of promiscuity. Then plug the second interface on the switch of the saem (but do not have the 2nd one a span port).

  Now, when the sensor detects an attack on interface 1 it will NOT send tcp resets the interface 1, but rather will send the reset tcp on the 2nd interface.

  Given that the switch does not accept that the tcp resets since the span port you need of the second interface for tcp resets in the switch.

  It is also possible with taps where the taps (because the taps have no way to accept incoming packets).

  The alternative tcp reset interface configuration is ignored when it is configured for online tracking. It is used only with supervision of promiscuity.

  Your switchports will be set to 'access' If you use the 'pair of inline physical interface' mode and it will be a trunk when you use "pair mode for vlan inline.

• TCP resets

  Hi all

  I would like to get your comments on TCP resets sent from IPS running inline.  If the sensor is configured to deny the striker, refuse the connection or even refuse to package, is there a reason to send a TCP reset?  It seems to me that send a just reset confirms a valid IP address to the attacker.

  I can see the reason to reset if the IPS is running in "Promiscuous" mode, as you would like the host to severe inside the connection, but I do not see the advantage to send it when the IPS is already denied the connection in one form or another.

  Thoughts?

  Thank you

  Jeff S.

  The document says:

  Excerpt from http://www.cisco.com/en/US/docs/security/ips/5.1/configuration/guide/cli/cliEvAct.html

  Inline package deny action is represented as an action of package ignored in the alert. When a package inline deny occurs for a TCP connection, it is automatically upgraded to an inline action to refuse the connection and considered a refusal flow in the alert. If IPS denies a single packet, TCP continues to try to send this packet even again and again, so IPS denies any connection to ensure forever, he succeeds with sends it again.

  In the case of a connection line refuse, the IPS automatically sends a one-way TCP reset, which appears as a unidirectional reset TCP sent in the alert. When the SPI refuses the connection, it leaves an open connection on the client (usually the attacker) and the server (usually the victim). Too many open connections can lead to problems of resources on the victim. So the IPS sends a TCP delivered the victim to close the connection on the side of victim (usually the server), who keeps the resources of the victim. It also prevents a switch which would also connect to switch to a different network path and reach the victim. The IPS leaves the side attacking and rejects all traffic of it.

  Deny connection line and deny attacking pair victim line seems to have the same effect in the end, except that "Deny the perpetrator victim pair Inline" has an entry in the big "Deny".

• 8.1 Windows reset loop crash

  Hello

  I have a laptop Aspire V5-572P-6454 who suddenly started bluescreening immediately after the "Acer" screen at startup.

  I produced a recovery USB and tried a refresh (due to a 'locked hard drive') and then I ran a "reset". Everything seemed fine until windows install profile. I select a name for my computer, a wifi network, and every time when he asks me to choose a name of user and password for the computer, it crashes with error:

  "Restart your PC on a problem and needs. We are only collecting the error information and then we'll restart for you. If you want to learn more, you can search online for later for error: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (AODdriver2.sys"

  and it restarts and the cycle starts again.

  My research has suggested starting in safe mode (cannot do it on a windows installation). Uninstall the drivers of AMD overdrive (cannot dispense with windows).

  I really want to do is to reformat and reinstall windows, but obviously I can't do without a 8.1 windows product key, which you guys do not provide that I understand.

  Any suggestions?

  the image link does not work.

  as a last resort, you can try stock 8.1 windows installation media and check if the error.

• HP 350 G1: HP 350 G1 CMOS checksum bad 502 & reset

  Hallo,

  I own a G1 F7Y99EA 350 HP, (shipped with BIOS version f.13, via the latest version of the BIOS HP is f.12!)

  Every time after that the power is off (whether it's battery or simply remove the battery) I get the CMOS checksum error (502) with reset. After the reset, everything works perfectly fine, I have to change date & time, otherwise a few software goes crazy.

  I run win7 pro x 64 and my system is in good condition, checked with the HP Support Assistant and HP Instant Support Professional Edition (online tool from HP). I installed the drivers from the Intel Rapid Storage Technology technology and HP 3D keep.

  I also have a boot mSata SSD (120 GB mS200 Kingston). The 750 GB drive only for data (no OS on this subject).

  Any ideas, suggestions?

  Thanks in advance

  Make sure your firewall allows file and printer sharing: If you use Windows Firewall, you can skip this section, because Windows Firewall automatically opens the appropriate ports for file sharing and printers when you share something, or turn on network discovery. (For more information about network discovery, see in what is network discovery? ) If you are using another firewall, you must open these ports yourself so that your computer can find other computers and devices that have files or printers you want to share.

• Unable to recover the TCP/IP connectivity & corrupt Winsock keys with error code 11003

  After being unable to solve the problems created by the McAfee download causing failure DComm and lost connectivity I uninstalled SP 3 and reinstalled.

  I have a corrupted Winsock2 registry and auto config proxy TCP/IP keys and detect the proxy appear as 'not available '.

  I tried to reset TCP/IP using netsh int ip reset c:\ reseting.txt and also the use of the patch tool.  The error code is the function IntHelper.dll in IPMONTR. DLL could start with error code 11003.

  I am able to visual determine that the winsock keys are corrupted, as described in kb/811259. I tried to reset the winsock2 registry keys by using the netsh winsock reset command. The error code is the IntHelperDll function in IPMONR. DLL could start with error code 11003.

  I would like any suggestions or ideas that anyone can have for the restoration of connectivity.

  Oh, and I'm not going to use McAfee products in the future.
