Integrated Packet Capture: CEF or process switched?

• Packet Capture on ids

  Hello

  We need the 'packet capture' setting on all the signatures of attacks on a joint-2 V4.1.4 and a sensor 4210 V4.1.4. We use CiscoWorks VMS for the configuration of all sensors, but there seems to be no way to enable this setting for a selection of signatures at a time. This is apparently a different setting than the ip logging (for which we can select a large number of signatures to be configured at the same time). It seems to me that the only way to change this is to go into each separate signature configuration and change the value there. But it is almost not doable. Any other possibility?

  Now that IPS Version 5.0 was officially announced (to be released early next month), I can tell you about some of the new features that can help in this area.

  The new IDM (Intrusion detection device manager) which is that tool for basic configuration for the web of the sensor will allow you to select several signatures (now the control key while you select each signature), do a right click to bring up a window of action event and grant shares of event (such as the Packet Capture, which was renamed ProduceVersboseAlert in 5.0) for all signatures in a few mouse clicks.

  So you will not need to manually edit the XML of the probe to make the same change to a large number of signatures.

  NOTE: I work in the team of sensor and therefore did not expertise on product ID MC (VMS). I don't know if this same functionality offers the IDS MC in virtual machines. But ID MC should, at a minimum, be able to import changes made through IDM.

  Some other new features are what we call risk score and event Action overrides. With the risk rating will now have a level of risk calculated from 1 to 100. The risk rating is calculated according to the severity of the Signature, the loyalty of the Signature (how well it detects that the attack) and the target value (how the target address is important to you).

  Mainly the level of risk is a method to better sort the order of importance of the alarms, but can also be used with the new feature of event Action more than wrinkles.

  Each type of action (such as ProduceVerboseAlert) can be assigned a specific range of risk (for example 80-100) rating. Any alert that has risk rating will have this action also made previously specific action by signature. (If no alert with a risk rating of 80-100 would have ProduceVerboseAlert added to this alert action, if she had not already been configured on the individual signature).

  The filters have also changed a bit.

  You can now name each filter on the sensor itself.

  And even to add a description to a new field of user comments.

  The filters now also filter specific actions (in 4.x all actions has been filtered, but in 5.x, you can filter the actions in the block for example or even allow the alarm to be generated).

• Multiple context mode, how do I download packet capture file

  Hi guys,.

  Is there a way to download the capture of packets from a specific context? I know I used to use https:///Admin/capture/ to download if it's just a context.

  The ASA uses mgmt 0/0 for the management and it is connected to a separate network of OOB. Only this network has TFTP servers to download the capture file. The context in question is in transparent mode. Its IP address doesn't have access to a TFTP server.

  Thank you!

• Packet capture vpn access list filter

  I just install a VPN filter to secure traffic between two of our facilities. As a good security admin, I am only allowing good ports and blocks everything else. Now I see one-way packet loss.

  I wanted to set up a capture of packets to detect which packages were being allowed and which were dropped. However, none of my packet captures are showing all the captured packets. I tried the following shots.

  capture the data interface type DPEP bullies xo [Capturing - 0 bytes]
  match ip 10.1.8.0 255.255.252.0 all

  capture the data type DPEP raw access-list 105 interface xo [Capturing - 0 bytes]

  capture the data interface type DPEP raw asa_dataplane [Capturing - 0 bytes]
  match ip 10.1.8.0 255.255.252.0 all

  It is certainly a problem of formatting on my part that I am does not detect traffic to subnets that the traffic that goes with success.

  Any help would be appreciated. Thank you.

  Hi Michael,

  do not change the VPN filter... you created a dummy access just to capture list and who as a rule and use it to capture.

• ThinApps tests during capture and build process when you use Horizon Workspace

  Hello

  We are about to make a client implementation of Horizon Workspace with about 40 ThinApps we still have for packing

  When we package apps, during the NBC process we will include the Horizon in the package.ini parameters

  AppID
  HorizonOrgUrl

  VersionID

  
  

  After that we capture the app that we will then have a test PC to test the ThinApp to ensure it works before it is added to the repository ThinApp and having created rights. However the ThinApp will not work because there is no entry of right in the workspace for even and the application displays the error message.

  
  

  How Pack applications and test them before you configure the workspace? Or can't we? It must create all the ThinApps, download them to the repository, wait for the workspace to scan them, create rights, then test?

  
  

  Also when we update an application using the AppID same and incrementing the VersionID value, the tester will be able to test this on their PC to test before upload to the repository Horizon ThinApp or the user will get the same error message horizon? We don't want to postpone until it has been tested. Or is it possible to use the old method of entire update where we keep the same .exe entry point and just update the dat a.1 file? This will break the Horizon integration?

  
  

  Thank you
  

  This allows ease of Management Horizon Workspace does not change behavior of the package. This is why I would recommend to run tests without activating the Horizon Workspace manageability. There is no way to run a ThinApp package with Horizon Workspace manageability enabled without Horizon Agent installed locally and having the right.

  Once the tests have been completed, you can enable manageability Horizon workspace by changing the package.ini or by running relink.exe - h.

  Same thing about the update of test blocks. Check the functionality without manageability Horizon active workspace and turn manageability Horizon Workspace.

• The vMA traffic packet capture

  I'm deploying a new VM vMA. I have the virtual machine on a different subnet than my regular production network. Everything is good so far except when I try to run the command 'vma-update' When I do that, I get a message "no route to host". I followed it down to the access list that I have on my switch. Do I have to do now is execute a capture of packets to see what IPS the vMA is in talks with so I can enable them through on my access list.

  What is the best way to run a capture of the vMA packages?

  Thank you.

  Well the URL can be solved in several addresses/etc, but I guess already know you that.

  Eaiest is to perform a tcpdump, it is not installed by default on the vMA, so you can get a YUM repo and configure another session in which you make a tcpdump while you're trying to run vma-update

  Someone tell me, what is "CCE output ranking" and why this is receptive used by my router?

  Hello Sebastian,.

  EAC is the engine of common classification. I think that its used to "match" traffic for features like qos, nat, etc.. ". Based on the "HS in you ' out, some features on the direction of the output are originally be punted packets. You can try "debug ip cef drop" for a few seconds while the meter is incremented, usually it will give a reason to punt. The most common reasons are listed below.

  ACL log or log-entry option (or)

  An unreachable next hop for a route (or)

  A missing arp entry for a next jump (or)

  Entry to arp for outside nat... etc.

• Need traffic Analyzer - Capture packets from CISCO

  I use a cisco router, I've created interfaces sup, I use public IPs - now I need to check the traffic flow...

  I need the same information below.

  1. IP source address

  2. source port

  3 destination IP

  4 destination Port

  5. date and time of access

  I want to capture the details above from the cisco router.

  What is the solution for this, cisco can help me in this.

  According to your hardware/ios, what you will need to check what features you have available and what it supports

  Most routers are limited that they cannot support SPAN but 3845 s can or you could focus on the use of the RITE feature

  Some routers also supported the monuitor capture buffer

• capture packets in pcap format

  Running a packet capture on an ASA 5520 and I want to transfer the bucket from capture to the pcap on my computer for analysis format. I can get a record ASCII packets copied by using the command "copy", however, I would like to transfer the PCAP dump using the command 'copy' instead. Does anyone know how to make this transfer?

  States of documentation (8.x cmd reference, pg 4-11) that I should be able to get the PCAP dump by using a browser, and the web interface of the unit via https, but I think the camera gets confused with WebVPN when I do the transfer attempt.

  Thank you

  Use the /pcap switch after the copy command. I had a few problems with the copy on the external interface for a reason, but if you make a copy of /pcap for flash and then copy the flash on your computer, it should work perfectly.

• Help to capture packets on a system MXP running F9.3.3

  Someone at - it a good set of instructions on how to make a capture of complete package on an MXP endpoint.

  I'd like to do something that I can open it directly in Wireshark.

  We seek to verify that the DSCP marking are sent and received on UDP traffic that is sent and received since a MXP.

  I have all the DSCP settings in the configured MXP, but I want to check that the markings survive at the end.

  Require Root access?

  I see that in a log rather than a full packet capture file?

  We use capturing packets in the regular TC7.1 of the bases and is working very well... wish they would add to the web interface MXP

  Thank you

  There is no way to handle this grimly on an MXP endpoint.

  So you have a switch that supports a monitor mode (okay we need to

  Trust the switch to show what you want to see) or some other capture

  a device that you can inject into the path.

  Good success.

• ESXi 5.5: Enhanced Capture packets at the host level

  Can someone explain how to use this new feature?

  Capture packets of improved host-level

  Network troubleshooting requires various sets of tools. In the environment vSphere VDS

  offers standard of monitoring and troubleshooting tools, including NetFlow, Analyzer SPAN (Switched Port).

  Remote Switched Port Analyzer (RSPAN) and encapsulated remote Switched Port Analyzer (ERSPAN). In the present

  release, an improved host-level packet capture tool is introduced. Packet capture tool is equivalent to the

  tcpdump command line tool available on the Linux platform.

  Here are some of the key features of the packet capture tool:

  • Available as part of the vSphere platform and can be accessed through the vSphere host command prompt

  • Can capture traffic on VSS and VDS

  • Captures packets at the following levels

  -Uplink

  -Virtual switch port

  -- vNIC

  • Can capture packets ignored

  • Can follow the path of a packet with details of time stamp

  Cannot find documentation for this tool and tcpdump-uw is exactly the same as in 5.1.

  The new command is run on the host computer and is called pktcap-uw, I just finished writing a blog post about it here

  The unit was sold as a single IP integration. My client needs Dual Switch with an Ericsson PBX. I received the license key of ORC, and I opened a folder of TAC.

  TAC said that the license file will not allow installation double switch integration. The Cisco SE on the account indicates that the license key will allow me to make the integration of the double switch.

  Who is right? I heard that the moderator here has all the answers :)

  The is correct. Any customer with a license 4.0 can do double switch. You don't need a special permit.
