• Help Server port security...

  I have install a VMware View virtual security server in our environment.  I install a second vSwitch use DMZ on the host computer and it gave a new group of ports for use of the DMZ.  Security Server VM uses the new DMZ port group.  I have that a dedicated server will switch to DMZ, then back to the DMZ port on our firewall.

  Our firewall is managed by our ISP (I'm a one man IT Department in a large (for a computer scientist, in any case) environment so it helps me to deal with other tasks).  After talking with them several times, they assure me that everything is configured correctly so that there must be a problem with my VMware setup which I don't see.

  I have an external IP address dedicated to security server I've had linking an internal IP on a DMZ subnet dedicated by the first paragraph.  I open ports UDP and TCP 80, 553-4172 for security server and also to pass these same ports on our view connection server that is located on our private network.  (I've changed port 443 by default to 553 as my original thought was that something must be blocking 443 on the side of VMware)

  I am with them in that port rules are simple to set up-side firewall so I do not know there is no problem, especially after talking with four different technicians who all looked Setup and confirm that it was accurate.

  If I do a scan of port of the outer harbour, 4172 appear as being open, but when I scan port 553 it is closed.  This drives me batty as it doesn't seem to be much to screw - up in terms of setting this up.

  I'm also curious how to require the use of RSA devices only for the customers who connect throug Security Server.  If I place a replica of connection to the server, will not be the same configuration be used on both servers, which means that I couldn't activate RSA on the other without having to be on the other?

  Thank you!

  Hi dyeltonDC,

  I guess you did a lot of configuration errors including an ExternalURL.

  Please go through this doc and video http://communities.vmware.com/docs/DOC-14974

  Clearly, this article explains how to configure PCoIP Secure Gateway and desktop access other components using Protocol PCoIP external network.

  Have alook at www.vmware.com/pdf/view-46-architecture-planning. PDF page 60 for detailed deployment sight firewall rules all using DMZ

  Everything should work properly once you configure the display according to these guidelines.

• Laboratory of port security exercise - do not behave as expected.

  Hello

  I'm working on a CCENT training lab to demonstrate the configuration of port security.

  I have a Catalyst 3550 switch software Cisco's IOS, software of C3550 (C3550-IPSERVICESK9-M), SE Version 12.2 (52), VERSION of the SOFTWARE (fc3). I have two computers connected on ports fa0/1 and fa0/2 with IP addresses of 10.0.0.20/24 and 10.0.0.12/24 respectively. Without active port security, each computer can ping successfully the other.

  As soon as I change the configuration to add port security on fa0/1 I am not able to ping between the two computers, nor can I ping 10.0.0.20 from the console of the switch, but I don't know why! If I delete it again the pings succeed again.

  I expect that the switch must learn the computer connected to fa0/1 MAC and stop if there is subsequently any traffic from another Mac.

  Interestingly, the 'show mac address-table' command shows that the MAC connected to fa0/1 when port security is not enabled. I don't know if this is relevant.

  Can someone help me diagnose what is happening?

  Thank you.

  Do you have any other platform to configure your lab? because it should work ideally and the configuration is fine. However, to complete your lab, you already have workaround...

  I suspect that this question is something related to the hardware you use or due to a BUG.

• N2048 port security does not

  Hi Experts,

  Only, we have deployed a new site that uses the Dell N2048 switches in a stack.

  Now we would add port security to the switch, Port-MAC locking to lockdown one port if another computer.

  According to the manual, to put in place we only need of to the port to locked under the MISTLETOE under switching, network security, port security.

  This does not activate it.

  We tried to add via the command line, in the ports of test, it now shows:

  switchport security of dynamic ports 1

  Still, port security is not enabled. There is another thing that must be enabled in the world to do this job or other commands?

  Thank you

  The output of port security-# show is as follows:

  Port Security Administration Mode: enabled

  It is possible that the tests were not done fast enough. I spent the time-out and ask them to test again.

  Thank you

• With the help of old gear series noon on El Capitan

  I have a Vox Tonelab SE effects audio Board (around 2004), there the old serial midi on the back ports. I hung with the help of a USB MIDI interface cable. While the USB Midi interface to the show in Audio / Midi set upward and also in the profile system for USB port it does not detect the Vox Tonelab so no communication lunch.

  There is a POWERPC application called ToneLabSE SoundEditor which I downloaded and installed in the hope he would install a driver but I guess that this obviously doesn't work on INTEL in any case. Using Wine I can run the PC version, but still no communication via midi.

  Someone at - it ideas, would like to get this Panel communicating effects via MIDI.

  Thank you

  

  

  

  Solved! Using the WINE app I've run the version of the PC of ToneLab SE editor application. So pretty unintuitively by changing the serial midi to USB, SERIAL interface cables that went to the and out on the Tonelab SE. Now of the Se ToneLab editor I can write banks of programs to hardware Tonelab, but unable to empty the banks since the material Tonelab to software. My main desire was to use Expression pedals on the Tonelab as Midi Ableton controllers and some of the switches to the control of the Looper stomp. Now I can do it all. Hooray!

• Help with the help of Airport Express with D-Link switch

  Hi all. I'm not an expert in networking and I'm having some problems with my home network now. Any help is appreciated. Thank you.

  I'm doing this configuration works for my home network, it's what I have atm:

  Modem (it is a modem with router WiFi included, but it is disabled)---> Airport Extreme (the "tired" model)---> 2 wired iMacs via LAN ports + 1 D-Link 8 port unmanaged wired via the third LAN port.

  The switch does not work. No port light is on in it, although it is on in the AEBS is connected to. All my iMac have an internet connection through EI LAN ports. If I plug my Apple TV instead of the switch that works too.

  I do something wrong or maybe the switch is defective? My switch is a D-Link - 1008a.

  Thank you!

  Everything you say tells us that the AirPort Extreme works normally with the Ethernet devices.

  You have a defective switch / power supply or faulty cable between the switch and the AirPort Extreme.  Test the Ethernet cable on another connection to make sure it works. If this is the case and the small light next to the Ethernet port on the switch does not, while the switch is defective... or... If the switch uses a power supply outside... the power supply may be faulty.

• With the help of VISA Write in parallel loops (multithreading)

  Hello

  I got the idea to set up four parallel loops on a quad core with four EHR via serial port independently. I use the PXI-8430/8 and I was told that an independent operation of ports is possible.

  What I did was simply to put in place four parallel for loops consisting only of a single entry VISA. With the help of the Tools > profile > find parallelizable loops, they gave me the following warning

  This loop For may or may not be safe to parallelize. Warning (s):
  -A node in the loop For can have side effects.

  This means, that the pilot VISA screws are not suitable for multithreading? With the help of LV2010

  Thanks for your comments!

  See you soon

  Oli

  Here's some good reading on paralleled for loops.

  Regarding the caveat, it's just that - a warning. If you write commands on a device and orders must be received in the order then you cannot parallelize the loop. If the order does not matter then go ahead. But in the case of VISA wrote that a parallelized loop going not buy you anything. They are intended for operations of calculation intnesive.

  Just stick to four loops.

• With the help of VISA with Windows 7 64-bit resource control

  Hello.

  My company has recently upgraded our laptops, and I now work on Windows 7 64 bit rather than Windows XP 32 - bit.  I reinstalled a bunch of basic LabVIEW 2009, hoping that the 64-bit Windows 7 operating system would be able to handle 32-bit LabVIEW 2009 without problems.  But trying to run our test system, the control of VISA resources does not work.

  We use it to get a list of the COM (RS232) ports on the computer.  But the list is now empty.  The only option that appears in the list, is the text "Refresh."  But nothing happens when I press it.  Is this a bug in LabVIEW?  I installed the latest patch that I found, so now I'm under LabVIEW v9.0f3 (32 bit).

  Many thanks for any help!

  LabVIEW SP1 has an x 64 native installer.  I'm running very well with drivers 64-bit on this disc.  I think that the later will have something to do with your problem.  See the com ports in MAX?

• With the help of semaphore with a Global Variable - correct use?

  Hi all

  I looked in the use of global variables and in my case, it seemed with the help of a semaphore is the appropriate solution.

  In my case, I use a global variable to store the State of the system. Asynchronous two with screw environment (same VI) will follow two COM ports to see if they get a ' login:' command prompt. If the COM port is associated with Alpha, Charlie, or Echo, it increments by 1, and if it is associated with the Bravo, Delta, or Foxtrot, is incremented by 2 GV. If the GV is 3, the rest of the code will run. In this case, it must be a port COM A, C or E; the other should be B, D or F.

  A VI parent is called inside a loop. He works for the first loop. He never adds up to 3 on the second loop, however. I can't understand why. Please let me know if my code is a poor use of semaphores, or if there is debugging I can try.

  I'm still relatively new to LV, so I'm sorry if my screws are difficult to read. I created this in LV2011.

  Thanks for any help!

  CelerityEDS wrote:

  The output of my time looping (wait GV = 3) goes to the structure of the case on the bottom right (clear SGS, PasswordEntry, etc.), so the GV get indeed consulted by the upper case structure right.

  ??

  Your right upper case structure does not run until your time ends in a loop.  The while loop does not stop until the total is equal to 3.  Where can increment you the world besides structures case you cannot yet?

  Have you tried in your point culminating execution of the VI in order to see how they are actually running?

  Another problem that I see.  Assuming that your first while the loop is going to end.  In the structures of your case, you lock the semaphore.  But you can never unlock the semaphore unless you have the right combination of conditions that allow you to get to the case that unlocks the semaphore.  The conditions are based on data that are read before the start of the case of structure, which means that data will not be read and changed until it all ends.  You have the timeout of your lock semaphore connected on one of the cases, but your semaphore lock can never timeout because you do not have a value on his entry time-out.  I think you have a situation where you can lock a semaphore, then arrive at a situation where you can not unlock, then wind locking up of your cold code.

  I don't really think that you need a semaphore at all.  I think you can protect reading and writing functional your overall using a global variable, i.e. the motor action.  Overall, I think you need to rethink the architecture of your code.

  Hi, Raymond J,.

  ·         Did you do changes on the computer before the show?

  ·         You get the error message?

  ·         What type of internet connection do you use?

  ·         What security software do you use?

  Follow these methods.

  Method 1: As the problem does not persist in SafeMode with network, perform a clean boot to see if there is a software conflict as the clean boot helps eliminate software conflicts.

  Note: After completing the steps in the clean boot troubleshooting, follow the section How to configure Windows to use a Normal startup state of the link to return the computer to a Normal startupmode.

  After the clean boot used to resolve the problem, you can follow these steps to configure Windows XP to start normally.

  This kind of behavior is very often due to antivirus.  You are using.  If its McAfee or Norton get rid of them completely.   There are others who are also incompatible.  Everything you try, make sure that the analysis of e-mail is disabled.   You can also try to repair the database and see if that helps (see www.oehelp.com/WMUtil/).  And see also www.oehelp.com/OETips.aspx#3
