• Pre shared keys used in IKE Phase 1

  Hello world

  Need to confirm if we use the buttons pre shared during IKE Phase 1 main mode and aggressive mode

  Concerning

  MAhesh

  The pre-shared key is used in both modes of IKE Phase I. With pre-shared keys, the same preshared key is configured on each IPSec peer. IKE peers authenticate each other computer and sending a hash key data that includes the pre-shared key.

• Understanding, IKE Phase I and II

  Hi, I've been through the concept of a lot of time, but what confuses me, is encryption algorithm and a key to the DH, how they go hand in hand in IKE phase II.  I understand phase I authenticates the vpn peers and negotiates policy ISAKMP which includes Exchange Diffie-Hellman and symmetric encryption example WITH or TDES.  What I don't understand is what Exchange Diffie-Hellman (key derived from the public/private function) is used for, it encrypts the exchange of IKE2 already encrypted with DES/TDES/AES.

  Also if m do not use PFS in Phase II, would I by using the same key DH derived at the time of the phase I, if yes which is secure enough?

  Another issue is when the peers authenticate each other and then the protocol IKE phase I policy are exchanged, happens in clear text?

  Could someone please explain the process step by step in the two phases stressing precisely on the Diffie-Hellman exchange and how it is used with encryption algorithms.

  Concerning

  Sonu

  Sonu,

  Looks like you want to go back to RFC to take a peek. We have also a series of documents explaining IKEv1 and goes with debugging.

  What you miss is that in IKEv1 (main mode), messages, 5 and 6 are already encyrpted, while the previous, including Diffie-Hellman exchange are not.

  MM5 MM6 is when we exchange their identities. Those who must be protected, where the DH before negotiating.

  Phase 2 is a separate Exchange protected with the result of the phase 1. The role of DH for the phase 2 is to ensure that the encryption keys are not from previous key material.

• To configure a serial port using Max

  Hello

  I inherited the code that configures the serial port using the old serial code that does not allow the user to specify the term tank and turn on the tank of the term. Any ideas on how this is done with the old serial code? I also tried to use MAX to set the term tank and allow it, I am able to communicate with my device series with Max and I saved the changes when I was. So when I run Labview code, my serial code fails because the term tank is wrong and it is also not enabled.

  Everything that happens with the definition the term tank and allows ideas?

  What you do to the MAX to the extent where the configuration of the serial port have no impact on the LabVIEW program. (EDIT: which means that you can change the configuration in the LabVIEW code.)

  If you load the old code in a version of LabVIEW using VISAS for all the stuff of series then the screw would have been automatically replaced by shell screw that NEITHER created for the old code. Inside, they use just VISA. More than probably the old code use via digital port numbers. For example, in the library of \vi.lib\Instr\serial.llb of , you will see these shell screw Serial Port' writing' for example, calls the 'Open Serial Driver' VI which simply returns a VISA session. It then uses the Write VISA. So you can define characters of termination by obtaining the VISA of "Serial Driver Open" resource.

  Of course, the best solution is to rewrite the code using VISA directly. It will be much cleaner.

• How to transfer files from PC to PC via a serial port using labview

  I need to transfer files (.txt, .doc, .xls) from PC to PC via a serial port using LabVIEW. Is it possible to transfer files, if so how to transfer?

  Yes, it is possible to transfer files with the serial port using LabVIEW.  The files are just collections of bytes and the serial port is good enough in the expedition of the bytes from one PC to another.  You must connect the ports series with a null modem cable.

  First, take a look at the example of serial communication.   In LabVIEW, go to the Help menu and select «Find examples...» ».  From there, you can search for "serial" or navigate to hardware input and output > series.  Select «Write series base» and Read.vi  Try this example to gain confidence on the serial communication methods.

  Then it's time to learn how to read and write files.  For this, the examples might be somewhat confusing as they deal with files that are presumed to have data of a specific type in them.  I would recommend just familiarize yourself with the functions in the file e/s palette.  Specifically, familiarize yourself with the following functions.

  1. Open/create/replace file - on the side of your destination, you will need to create the copy of the file you are trying to transfer
  2. Close the file - when you're done reading or writing to a file, you must close it.  It cleans the memory used and finalizes write operations that are still floating in the write buffer.
  3. Read a binary file - is the best way to play a file when you don't really like what type of file it.  In your case, you just want to get these read bytes and sent so they can be written down instead of destination.
  4. Write to a binary file - next to the destination, is what will store the bytes in the file that you created with the number 1.
  5. Size of the file get (under the range of the advanced features of file) - you need to know how big the file is, so you know when you are finished.

  OK, so once you are able to create files byte write and read bytes from existing files, you can move forward.

  I suggest the basic method is to have the user specify a source file on the source PC, and a folder on the destination computer.  Then find the size of the source file using the number 5.  Divide this number of size by the number of bytes that you want to transfer to the times.  The series pads are usually around 32 k (if I remember correctly) in order not to exceed that.  Now start to send data by reading a number of bytes and this string output wiring to the feature of writing VISAS.  On the side of destination, you will want to monitor the serial port for bytes and read when they arrive.  This string of yarn to the writing of the function of binary file to add them to your destination file.

  This is the basic outline of how to do it.  He needs to not to overload him write and read buffers on the serial ports.  Initially, you can use delays on the side sending to make sure that the side reading has enough time to digest.  To make things faster, you can bring in a control of flow.

  If all that sounds a little intimidating, there are there Alliance member companies (such as the automation of PrimeTest) who can write this code for you and even provides a turnkey for you solution.

  Happy wiring,

  Crypto isakmp nat-traversal 20

  Last week, I configured a new L2L VPN. For IPSec phase, I have added the below mentioned lines...

  card crypto toremote 20 match address remotevpn2

  card crypto toremote 20 peers set x.x.x.x

  toremote 20 set transformation-strong crypto card

  life safety association set card crypto toremote 20 28800 seconds

  Now my question is the seq n20 crypto map is not matched with any IKE phase 1 seq no (1,9,10,30) that is already configured. But the VPN is up and working fine. How it associate a particular phase of IKE IPsec?

  If you want to configure a new virtual private network with different parameters in the IKE phase 1like 3DES, SHA1, life 86400, what are the configuration that I have to do in phase 1 of IKE?

  Kind regards

  SOM

  isakmp policy number and the number of ipsec policy do not match your ASA or with the other end. They are two distinct phases of negotiation. The ASA will compare your policy at the other end, starting with the smallest number of policies, until a match is found.

  I usually put safer policies first (i.e. with the lowest number of the police).

  To create a new policy, just add it with a new policy number, anywhere where you want in the order.

• What are the ports used by the Cisco VPN Client?

  Hello

  I need to open my outgoing traffic on my firewall to allow two interns (LAN) Cisco VPN Client to connect to their Internet virtual private network.

  I already opened the port 500/UDP, but they are not able to connect. If I open all outgoing ports, they can connect.

  What are the ports used by the Cisco VPN Client?

  Thank you

  You need to open:

  UDP 500

  ESP protocol

  You must also open the UDP 4500 port (if using NAT - T).

  In addition, if the clients are connecting to a VPN 3000 Concentrator series and it is configured for all other options of NAT-transparency, corresponding ports must be open. By default:

  1. If using IPSec over TCP 10000, then open TCP 10000.

  2. If using IPSec over UDP 10000, open UDP 1000.

  Could adjust your game of transformation?

  Right now you have: crypto ipsec transform-set MY-0WN-TS-MD5 ah-md5-hmac esp - aes 256 esp-md5-hmac

  Could you change strictly cela ESP or AH on both sides rather than mix them.

  There is a known issue with the ASR and the mixture AH / ESP in ipsec configuration. I'll post below:

  CSCtb60545 / CSCsv96390

  Mixing protocols AH and ESP in transformation defined on ASR may not work. This is an enhancement request who will introduce support for this.

  Symptoms:

• Blocking ports using a virtual Super Hub 2ac (VMDG490) machine

  Hi all

  My first post and hoping that it is in the right place. A few days ago, I received my upgrade to a SHub1 to SHub2ac. After a speed problem. I created 4 blocking rules port for one of my computers successfully, but when I try to create the same blocks for my other computer I get an error of "the port selected range overlaps with an existing rule".

  I gave the rule a new name and have obviously used the ip addresses of the other boxes on the network. It worked well on my old SH1 then why not on an alleged update?

  VM, I called and they had no idea if it was possible and showed me tech, alas, they had no idea that is then reported to me their salary for support Dept. They said it couldn't be done? As a Department tech VM and the pay per help guys were unable to offer advice, other than to block ports through your firewall software. Can be done using Bitdefender, I can see (it's another can of worms in itself).

  Any help or advice of Netgear technicians or other users of the popular home network. As seems a downgrade of the former 1 SuperHub that would allow any amount of blocks of port by using port numbers providing the name of the rule was different and the IP addy has been changed, is there a possibility of a upgrde of firmware to re - enable this option? Or the guys from VM need to RTFM

  Any help is much appreciated in this matter.

  Best regards.

• CAN transmit/receive same Port using USB-8473?

  Hi, I'm new to the CAN interface. I have a USB-8473 attached to my USB using Labview 11. I write labview routines to use the port, but since I don't have 2 of them, I thought just to transmit a data frame and read it on the same port for testing purposes. Currently I'm using transmission same reception Port.vi example, just to see, if it works, but when I run the VI and transmit data and then set the RTR bit to receive the rear frame, nothing is ever reported. Are there any additional settings I should do before using the device CAN 8473. I even tried setting the attribute of free reception as well and nothing ever gets the spokesperson. I use a baud rate of 125K on CAN0 flow. Can someone help me understand why it does not work?

  Thank you.

  No.... everything will be virtual (pass on 256, 257 reception). NI-CAN comes with two virtual ports internally interconnected. They are not exactly the same as a real port, but it can help you to carry out tests.

• What port uses the part of the back-slash?

  I have a VPN connection and try to \\computername\c$

  Anyone know which ports the------uses hand admin?

  Thanks in advance.

  Windows network uses NetBIOS over TCP/IP (NetBT) Protocol.
  This protocol uses the following ports:

  Port UDP 137
  Port UDP 138
  139 TCP port

  See:
  "Windows NT, Terminal Server, and Microsoft Exchange Services Use TCP/IP Ports".
    <>http://support.Microsoft.com/kb/150543/en-U S >

  Of course, these protocols are probably by tunnel through your VPN port.
