  Hello world

  I support the ASA according to the customer. I'm new to the world of the SAA.

  Users especially to check whether or not ASA allows specfic port.

  I don't know how I can check that.

  Is it possible that I can determine if ASA is blocking port or not?

  If ASA is blocking port what steps I must take to allow ASA allow specific port?

  Hello

  You can use the command packet--draw to get the results you're after... that is to say if a 10.1.1.10 client attempts to access google dns, you can use the following syntax:

  plotter of entrance inside the 10.1.1.10 udp packets 53 8.8.8.8 53 detailed (I may have the syntax a bit but you can tab your way through this).

  Thank you

• 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.

• How can I make sure that any firewalls (versions of software or hardware) does not block port 443 to access?

  How can I make sure that any firewalls (versions of software or hardware) does not block port 443 to access?

  Hi Anna_753,

  Usually, you would receive messages from any program if it is impossible to access the port.

  If you want to check if the port is accessible, then you will need to check the firewall settings.

  Each firewall has its own parameters for ports of the computer.

• Internet service provider blocks Port 80 # & 1024

  How to choose which ports to open are? Randomly? I think I'm good with the configuration of the part, but don't know which to choose... dm

  Solved! Finally went back to work and connected then and there it was... I guess than TZO too k care the blocking port "80". I wonder why you need to open two ports? One is a back-up? Or, you need and and one out?

• Windows PE and 7 clients trying to connect to servers on port UDP 500

  We have a lot of nie on our internal firewall from various machines in our area who are trying to connect to servers on port UDP 500 that are fill newspapers on the firewall. Servers usually aren't domain controllers, some are Terminal Server servers and one our imaging Server (LANDesk). Clients fail to connect to the VPN either. We do not use IPSEC anywhere in their own country.

  It seems that UDP500 traffic is generated when accessing other services on the server such as RDP or file-sharing, not all clients are and stop the IKE and AuthIP IPsec Keying Modules service on the client seems to stop packets. So I think I know what it does but I don't know why. I have some screenshots of our managed service provider package and connected remotely to a system running Windows PE, looked with TCPView and valid traffic that packages stop when the IKE and AuthIP IPsec Keying Modules service is stopped. I do not think its malware.

  I'm really excited to know what mechanism is causing these packages and knowledge if we accept it or not.

  Any advice would be much appreciated.

  Thank you

• blocked ports affecting http

  On recommendation of Cisco, I have blocked ports TCP 3127-3199 out my interface "inside". Seems that these are commonly used for mydoom ports. Now, when the user's browser uses these ports as source ports they don't have until it exceeds this window. Has anyone seen elsewhere this problem and how do you work around it?

  Roland,

  A MyDoom attack can be launched from the outside (entering your local network) or inside (out to your local network).

  IF YOU WANT TO BLOCK INCOMING OF MYDOOM ATTACKS:

  If this traffic passes through a firewall, then by default, the sessions opened from the outside are blocked unless explicitly allowed entering. If you use a router with ACL, then you must configure an ACL in the INCOMING direction and apply it to the interface from the OUTSIDE as such:

  --------------------------

  For routers:

  access-list 111 tcp refuse any any 3127 3199 Beach

  interface

  IP access-group 111 to

  --------------------------

  In this case, you'll experience the question that you're already because when a web server returns a bunch of session to the client (browser), then the destination ports match the ACL and the router will drop the session. To remedy this, we can apply an IOS Firewall to the external interface of the router. The ACL to block incoming attacks of MyDoom cannot while the router will maintain session state information in its table.

  IF YOU WANT TO BLOCK OUTBOUND MYDOOM ATTACKS:

  Then the ACL must be applied 'in' on the 'inside' interface

  --------------------------

  For the PIX Firewall:

  access-list 111 tcp refuse any any 3127 3199 Beach

  access ip-list 111 allow a whole

  Access-group 111 in the interface inside

  --------------------------

  --------------------------

  For the router:

  access-list 111 tcp refuse any any 3127 3199 Beach

  interface

  IP access-group 111 to

  --------------------------

  This should provide you with enough information to work on your issue.

• Looking to block Ports on AirPort Extreme

  I'm looking to block specific ports when you access a particular service online. I the number of ports I need to block already, but I do not know how to block. I use an iMac running OS X El Capitan 10.22.6 and an AirPort Extreme v7.6.7. Any tips?

  To the airport

  By default all IPv4 ports on an AirPort base station are closed (not ' hidden') to the incoming traffic from the Internet, like the base station uses a simple based on NAT "firewall." However, all ports are open going out.

  If you use a service on the Internet that you send the traffic, the return traffic will access specific ports that the application told him, to complete the loop. If your goal is to 'close' this loop, then you will need to port forward that return traffic to a client is no local network as a potential solution. Not sure how your app will be with some communications being blocked.

  Nevertheless, the solution is to port before the unwanted incoming ports to a local IP address that is outside the DHCP for the network scope. By default, the DHCP of the airport service provides addresses in the 10.0.1.2 - 10.0.1.200 range. You would then be the port forward to attack from 201 up to 254.

  For example, if you want to block the 800 port, you would put in place a port card in AirPort Utility as follows:

  • Run the AirPort Utility.
  • Select the base and then station, select change.
  • Select the network tab.
  • Select it '+' plus button under Port settings.
  • Enter a description in the Description box.
  • Public UDP ports: 800
  • Public TCP ports: 800
  • Private IP address: 10.0.1.201
  • Private UDP ports: 800
  • Public TCP ports: 800

  For your Mac

  To block all incoming connections to a specific application, use the system preferences, as follows:

  • System Preferences > Security & privacy > select it '+' plus button to add the application.
  • Select the option "Block incoming connections" for this application.
  • Click OK.

  Note: If you want more control over the software firewall in OS X, you need to look into a third party app that does this. Some of them are: Murus and Little Snitch

• Why is the port udp 137 used during a remote desktop session?

  I am currently seeing a lot of messages on my firewall indicating port 137 udp is blocked.  I think that when I use remote desktop to a remote system, which attempts to connect to me via the udp port 137 remote systems.  If this is true, why?  This is necessary or if I can change this behavior?

  Hello

  UDP 137 is used by NetBIOS in Windows 7 file sharing.

  According to what you are doing when you use Remote Desktop on your network, it can call the UDP137.

  If it does not interfere with something functional you need to do, leave him alone. The Job firewall is to block aspects of network traffic. You don't have to feel 'sorry' to him do his job.

• Read the serial number of the device in LabView COM port

  Hello

  Is it possible to read a device COM port number in LabView? I would like to make an initialization of the program following the right port COM of a device, for example a USB temperature reading device, and set the COM port as the correct port at the start of the main program of LabView. I want to do that, because a USB device gets usually different dedication of COM port on different computers. Our application runs on 80 different computers. A program like that would be very nice.

  Can someone help me?

  Paal

  Another thought. It also has a place where certain standards can save you a lot of time.

  You have 3 dongles by machine. When setting up a computer are these three dongles * always * assigned to, for example, com 3, com 4 and com 5.

  Similarly, always check that instrument 1 is always on com 3, tool 2 is always on com 4 and 3 device is always on com 5.

  This convention will also simplify debugging...

• LabVIEW block in serial communication!

  Hello.

  I use pl2303HXA (usb to UART converter) in my design data and sending of microphone for pc in LabVIEW 2013 x 86.

  When I tried in a terminal CODEVISION, everything is OK and each microphone send to a PC, Hypertermial or Terminal CODEVISION is received correctly.

  but when I run LabVIEW, it works for a few seconds and Communication all of a sudden abrupt and LabVIEW crash. You can see in picture I capture from my Telechareger below. Why LabVIEW hang?

  

  the image is the front of my VI.

  every time it blocks, I have to restart LabVIEW and test again. in the meanwhile I have to said hang occur randomly.

  Thank you.

  
  

• LabVIEW Serial port wait event with Serial Termchar

  Hello world!

  I'm quite new with LabVIEW and I'm having some trouble trying to communicate using the serial port.

  I'm trying to detect a data frame with an 'X' as the terminal character sent to the serial port.

  The problem is that with the VI attached on this post I am not being able to detect the chariot of the term series.

  I tried to make some changes to fix this, but I can't.

  In VI, I used a function of Type Cast when I was using the wrong ASCII for 'X' value, but it still the same.

  Can anyone help with this?

  Thank you!

  Best regards

  Omar

  This will work only if your message can never be more than 8 characters including the character. term set this value to 1000 or something that is guaranteed to be always bigger than the size of your message and all should be good.

• Mgmt of RVS 4000 HTTP interface blocks Port 80 @ & DHCP stops working

  It's the RVS 4000

  Firmaware version 1.3.3.5

  STARS Chipset 9202

  64 MB DRAM

  8MB Flash

  BACK, Block WAN Rq, mgmt remote all OFF

  IPSec Tunnel that none used

  Internet connection is DHCP

  LAN is set to DHCP with multiple defined static devices

  DMZ is dsabled

  Functionining as a gateway

  Time is defined via NTP & NRC

  IPv4 only

  Everything is pretty much dedault with the exception of the QoS

  Trust mode is the Port, the value 4, 4, 4, 1

  (Port 4 has a Linksys ATA connected to VOIP services)

  SIP Port redirection is enabled for 5060

  **********************************************

  ¸*********************************************

  Every day or so the router becomes immune to the mgmt HTTP interface, as well as offers are no longer the DHCP services.

  When this happens the only cure is to reboot the power.

  Everthing comes back on line very well, but NEWSPAPERS are initilaized so not given to understand what is happening.

  My next step is setuo a syslog server and have copied newspapers.

  Anyone see this kind of behavior before?

  Any ideas?

  Thank you

• Blocked ports

  I have a Verizon DSL with model 6100 modem and a Linksys WRT160N router. Recently, I decided to install home security cameras to monitor my home time at work. I followed the instructions of Setup DynDNS... and is able to access the video with computers connected to the router. But once on the router, I got a message of 'time' out  I ran the port checked and found that none are accessible. I'm confused if Verizon or blocked modem these ports or the router has not been defined properly?

  Thank you for your help.

  As your Internet service provider is DSL, you must convert the modem in the bridge of Mode.After convert the modem into bridge mode, configure the router with PPPoE settings and it will work. !!!
