• Window.Open is not supported by 40.0. + (39.0.0 and below of), can this please be corrected?

  I often visit websites that will be, when the user clicks on a link or an action takes place, a new window will appear with the contents of the URL or the desired action (as when you pay a bill it is redirect to another provider who then handles the transaction). A few days earlier, I tried to pay a Bill and Firefox gave me a blank window but inspect 'command-u' shows that the HTML is there. When I did it through Safari, it worked. Today, I wanted access to a ProQuest database via a link provided by the UCLA Library and I got the same result: an empty window with HTML code appears when 'command-u' is used. Surprisingly, paste the link in a new browser window did produce the content. But the original empty browser window not showing anything even if it is re-charge. Both of the actions that I describe are produced by scripts on these two very different sites, but Firefox response is the same: a browser window empty.

  To isolate it, I tried the simplest: I used window.open in my work site to send the visitor to the Publisher of origin of my work. The following code snippet is an example of this approach:

  "" < a href = "http://link.aps.org/abstract/PRL/v72/p1658"

      onclick="window.open(this.href);return false">original publication</a>.
  

  By clicking on the link used to open a new browser window at aps.org.

  But now it does not after the upgrade to 40.0. + (currently at 40.0.3).

  It is, as far as I know, a call HTML "supported". And it works for 39.0.0 up to 34.0.5 (could have been furtherback, but I don't see the point).

  I think that it is a major flaw with 40.0. + and must be fixed as soon as possible.

• Site to site VPN with router IOS

  I want to create a VPN site-to site on the Internet. On the remote site, aside from the VPN to the head office, there should be no traffic not allowed in internal from the Internet to the network and that there should be no traffic from the internal network to the Internet allowed. The internal network will run a private 192.168.x.x address range.

  I'm going to use a Cisco 2811 router integrated of services on the remote site and this will last an IPSec VPN that will end a hub at Headquarters. I understand that this router has an IOS and IPS firewall built in.

  Would I be right in thinking that because I don't want to have access to the Internet (except VPN) or should I configure IOS firewall features on the router? And there is no point in the configuration of the features IPS wouldn't?

  My thought is that only an entry in list of unique access to deny pi a whole applied inbound to the interface that connects to the Internet would be the best strategy. I think that the command "sysopt connection permit-ipsec" should allow the VPN to form even with the ip address to deny any any ACL (or is it just a Pix command? If Yes, then I have to allow ESP and UDP 500 (ISAKMP) from the public address of the hub at Headquarters to allow the VPN to form wouldn't I?).

  Think I'll probably expand slightly the access list to allow the icmp Protocol, ssh and https traffic from the IP address of firewall seat outside so that I can monitor the remote site and access it safely if the fail VPN.

  And I wouldn't need one access list on the interface connected to the internal network I would like because the range of addresses would be not routable, so they would not be able to initiate connections to the Internet (all the trffic to the remote site is specified under a valuable traffic to bring up the VPN)

  Use one of the IOS Firewall inspect commands or the IPS would be useless and have no effect in this case wouldn't it?

  I really just need to know if the ip address to deny any any ACL on the external interface on the remote site is the best solution (and the simplest), and whether it will be safe.

  We used to use fiewalls Pix for remote VPN site to site, Amazon refuse incoming connections on the external interface by default but now I have been informed that these series 2800 routers will be used later, so I would get my thoughts straight and be able to build safe to do the same work all existing PIX are doing (they are all installed for just the VPN at Headquarters as in) the first paragraph).

  I would like any advice or thoughts on the subject. I don't know there must be a ton of people who put routers for the same purpose.

  Thank you in advance.

  Pete.

  I did a lot of implementations site VPN to another using IOS routers. They work very well. Based on my experience I offer these comments and I hope that they will help you:

  -you don't want a list of incoming access on the external interface, but you want more in it than simply refuse an ip. There is no permit-ipsec sysopt connection in IOS so you want to certainly allowed ISAKMP and IPSec/ESP. I suggest that you also want to allow SSH. I would like to allow ICMP but only starting from the address space of the network head end. I do not allow HTTPS since I generally do not allow the http server on the router. If you want HTTPS then certainly enable it. To facilitate the ping and traceroute on the remote I frequently allow icmp echo-reply, timeout and unreachable port from any source.

  -I want to put an inside interface access list. There are certain types of traffic that I don't want to send from the Remote LAN. I have usually refuse any trap SNMP or snmp for LAN devices and refuse out of the local network icmp redirects. I also often configure RPF controls inside interface to catch any device which is misconfigured.

  -If you want to allow SSH when the VPN is not active (and I highly recommend that you do) then you will probably need to configure at least 1 (and maybe more) users and password of the router ID. And you want to configure authentication on the vty use local authentication if the head end authentication server is not available.

  -I'm not clear from your description if you plan to run a dynamic routing via the VPN Protocol. I wish I had a dynamic routing protocol because I want to announce a default route to the remote control via the VPN. I do not locally configure a default route on the remote router. This way if the VPN tunnel is up there is a default route pointing to the tunnel and if the VPN tunnel is not up then there is no local route by default and users on the remote database can not access the Internet. It is a simple and very effective method to ensure that all user traffic must pass through the central site.

  -regarding the routes defined on the remote router, my approach is that I define a static route for the endpoint of the tunnel to allow the tunnel to implement and I set up static routes for the subnet to the head of line I can SSH. And I do not configure other static routes the on the remote router.

  -You probably want to disable cdp on the external interface and also to disable the proxy-arp (and I don't make any ip unreachable).

  -There is frequently a problem when using VPN site-to-site with fragmentation. If a device on the local network sends a frame of maximum size, and then the router needs to add additional headers for IPSec, then the frame is too large and requires fragmentation. I like to use tcp adjust-mss ip to control the chunk size for TCP traffic and avoid any problems with fragmentation.

  -I don't think you want to set up the firewall or IPS from the features of IOS on the 2811.

  I hope that your application is fine and that my suggestions could be useful.

  [edit] after posting my response, I read through your post again and realize that you make to a VPN concentrator. The approach I have proposed on the execution of a routing protocol works for me because I usually have a router IOS in mind. It would not work to connect to a hub.

• Internet access from the default remote gateway? NO SPLIT TUNNELING

  I am facing a problem for a long time, I have an ASA5505 I went through a lot of config and research until I got the inside interface to be able to go to the internet; However my VPN clients are unable to go to the Internet. Now, here's the network config:

  -J' have a router (which is a modem and a router and an AP) 3 in 1... This router is connected to the ISP with a coaxial cable. the Interior is 192.168.0.0/24 network.

  -L'ASA is connected to rotate inside the network of its ' outside the interface.

  -L' SAA within the 192.168.1.0/24 network is a configured static gateway already (which is the router) outside the int > default gateway 192.168.0.1 (which is the internal IP address of the router).

  -Inside the ASA computers are able to connect to Web sites (but I can't do anything outside the network of CMD PING)!

  -When a VPN cleint to connect using IPsec (without certificate) by using a Cisco VPN client software, the client can ping and do the remote desktop connection with computers on the same within the network (192.168.1.0/24) but can not pass the Internet even know that other computers on the network can go to the internet.

  -One of the computers on the network (the inside network) is a DC server 2008 R2 which can go to the internet, as I mentioned above.

  What I'm trying to do is have the VPN clients to be able to go to the internet with the help of which the ASA inside the NETWORK card as a default gateway (192.168.1.1), I already have the VPN configuration with the name of the group, preshared key, user name and password and without the split tunneling (which is what I want)

  Thank you

  Hello

  The most common problem by getting ICMP to work through the ASA failed ACL or the ICMP Inspection rules.

  Check your configurations of current ' policy-map ' on the SAA with the command

  See the race policy-map

  I assume you have the default configurations 'policy-map' on the SAA, that are attached to the global

  Under ' policy-map ' configurations, you should see several 'inspect' commands. Pass under the correct configuration mode (where the current commands are found) and add the following

  inspect the icmp

  inspect the icmp error

  Then retest the ICMP through firewall.

  In regards to the VPN Internet traffic, we would need to know the level of Software ASA which you can check with the command 'show version'

  You must first verify that you have this command

  permit same-security-traffic intra-interface

  This will allow the traffic to the VPN users access the interface ' outside ' of the ASA, get PATed and then leave again through the ' outside ' interface. Without the command above it will not work. Will never go the VPN Internet user traffic through the interface "inside" of your ASA.

  Then, you will also need the dynamic configuration PAT for your VPN users, so they are translated at the same IP address that users of LAN behind the ASA. This format of configuration depends on the software level, that I mentioned above

  On a SAA running 8.2 (or below) you would usually have this configuration

  Global 1 interface (outside)

  nat (inside) 1 0.0.0.0 0.0.0.0 (or the mentioned specifically LAN)

  To activate the dynamic PAT for VPN users that you would add

  NAT (outside) 1

  On one ASA 8.3 running (and above) you can configure the dynamic PAT for users of VPN in the following way

  network of the VPN-PAT object

  subnet

  dynamic NAT interface (outdoors, outdoor)

  It should be. Of course, you could have a configuration that may replace it, but I doubt it.

  Hope this helps

• Firewall Web VPN with ACL access

  All,

  I have an EZ basic VPN and my external interface has a standard ACL firewall.  I cannot VPN into the system very well and have access to all the internal elements, but I have no internet access.  The router log shows:

• Inspect the IP fragment command max and its effect on Anyconnect SSL

  I have a client with a Cisco 3825 works as a firewall and "IP inspect fragment max on 256 timeout 1 ' is configured on the inbound.

  Can or this command will have any negative effect on the Anyconnect of Cisco SSL customer communications?

  Do not believe that the inspection of the fragments will particularly affect AnyConnect traffic. It will be inspected for a maximum of 256 fragments before start up package for inspection. It will affect all traffic through the router, but not specifically for traffic AnyConnect.

  Hope that helps.

• selection by tcp/ip and labview 1742 smart camera inspection

  I m working with two smart cameras NI1742 where I have an inspection for various products, I m try via tcp/ip and view lab 2010 select inspection for each product. I configured the tcp/ip connection and test it with the vision builder ethernet Terminal, this part works fine, but I can´t do this with Labview where I show images of smart cameras via shared variables.

  If anyone knows how I can do? Please, I will be grateful.

  It's my code, but there is something that's not going to.

  Thanks and greetings

• Send data and receive commands by VBAI of VB or c#

  Hi, anyone has examples on how to send VBAI data and receive commands by VBAI of VB or c#.

  I intend to hand over command to the VBAI on and outside, get the image and stop start.

  For the data to be send are the result of the calculation of the calculator function. The data send each time to do the math.

  I have search the forum and I know that this can be done by using labVIEW. However, due to the requirement of the question, I can't do it using labVIEW.

  Thank you.

  Yen

  Hi Yen,

  "" "You're almost there. '" Here are the steps for this example works.

  Once you open the inspection in Vision Builder, go to tools > Communication Device Manager...

  You must create a Modbus master device, which corresponds to your communication of VB with Vision Builder application.

  Click on the new device. Give it a name, say "VB program".

  Select Modbus TCP for the Protocol.

  Click OK.

  On the Modbus server line, click Start Server. This starts the background task which is listening on port 502 for incoming Modbus messages.

  Click OK to exit the dialog box.

  Now, a couple of things to understand about Modbus: the Protocol specifies how a device Modbus master can read and write registers located on a slave device. Vision Builder has 4 64 k save tables:

  -Coils (read/write binary, by the master).

  -Tor inputs (binary, not read by the master).

  -Entrance to the registers (16 bits, not read by the master).

  -Holding Registers (16-bit, read/write by the master).

  The tolerances of the inspection reading read minimum and maximum intensity in Modbus 0 x 0 and 0 x 1 operating records.

  If you want your VB application to write these values.

  Here's the Modbus function codes. You can get the full list by downloading the specification to Modbus.org Modbus.

  0 x 01 reading reels

  0x02 read discrete inputs

  0 x 03 playback record keeping

  0x04 read input registers

  0x05 write single coil

  0 x 06 write single register

  0x0F write multiple coils

  0x10 write multiple registers

  To use your example Modbus program to read and write registers Vision Builder, first enter the IP where Vision Builder is running:

  127.0.0.1 (localhost)

  For this example, use the function Code 6 to write a single business registration.

  The Modbus data must be formatted as follows: the first 2 bytes are the starting address, the following 2 bytes are the value (U16) you want to write to the registry. So to write the value 1 at 0 (corresponding to the intensity of the min), the data value Modbus 00000001. Click on send.

  Now, to set the maximum intensity at 50. Set the data to 00010050. Click on send.

  Step write data written minimum intensity of step to check the presence of CAP in the Modbus 0 x 0 registry entry and the status of the step in discreet entrance 0 x 0.

  To read the intensity Minimum written by VBAI, the value of the function 4 Code (enter reading registry). For the Modbus data, the first 2 bytes represent the address, 2 bytes, the number of registers to read. The value of data Modbus 00000001 to read a single registry entry to address 0. Click on send. The response data can be for example 0x1E, which corresponds to 30 decimal places.

  To read the status of the step, set the function Code 2 to read discrete inputs. The value data 00000001, to read the first register of the discreet entry table located at address 0. The response data is 0 or 1 (success or failure).

  I hope this helps. Let me know if you need other information. But this should help you get started.

  Best regards

• Inspection ASA DNS debugging

  How can I debug ASA (inspection of DNS 9.1 (1))?  Specifically, the ASA does not block queries associated with applications to dig as follows to never reach "the.name.server":

  dig @the.name.server t ptr 1.2.3.4.reverse.somedomain.com.

  And I would like to be able to see how he responds to the query (and decisive) to block.

  I'm really just one question for the instructions of debugging that might help me to solve this, but if someone can tell me what it is this query that the ASA does not like what would be very useful.  It blocks the request even with very basic inspection enabled:

  policy-map type inspect dns preset_dns_map parameters   message-length maximum client auto   message-length maximum 4096 policy-map global_policy class inspection_default   inspect dns preset_dns_map

  If I have the dns preset_dns_map "inspect" in it the ASA blocks the request, but if I remove the dns preset_dns_map "inspect" the query works fine.

  (Just to be clear, the customer in question is located on the SAA within the interface and "the.name.server" is on the external interface).

  Hello

  I didn't do it myself at any time

  I found that there is at least 3 different debugging associated controls to "check the dns".

  • debugging inspect dns errors
  • debugging inspect dns events
  • debugging inspect dns packets

  Maybe some of them lighting up could bring some clarification to whats happening.

  Under the following configuration mode

  type of policy-card inspect dns preset_dns_map

  parameters

  There is an option called

  ASA(config-pmap-p) #?

  Strategy-card MPF parameter configuration commands:

  audit of the DNS Protocol-enforcement message format

  Weather disabling this default setting with "no protocol-enforcement" helps or whether it is better the purpose of having to 'check the dns' I don't know.

• AIP SSM-10 - how to check traffic being passed for inspection?

  Hello

  I've implemented an AIP - SSM on our ASA5510 for the first time, as a result of this excellent guide, http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a00807335ca.shtml.

  The difference between the environment used in the doco and ours are the specifications of our ASA and module, the following IOS version 8.0 (4), version ASDM is 6.1 (3), the version of the application of SSM is 5,0000 E2.

  I have followed all the steps to enable connectivity to the module of the ASDM, created the access list to allow all ip traffic to be transmitted to the inspection module, map of the class and the political map indicating promiscous mode, relief. The service policy is applied throughout the world.

  The problem I'm having is that when I try to check as indicated on the guide to the alert of events see the command on the CLI module I don't get any output, so I don't know if the traffic is passed to the module. Can someone plese help me clarify this?

  Kind regards

  Esteban

  Run 'show conf' on your AIP SSM CLI. Check interface GigabitEthernet0/1 basket of the MSS background assigned to sensor virtual vs0.

  If it does not, then run "setup" and towards the end of the installation wizard, there will be an option to change the interface and the virtual sensor configuration. Use this option to change the configuration for sensor virtual vs0 and in the interface.

  You can also run "show stat vs0 virtual sensor" to see the number of packets being crawled by vs0.

• cannot ping remote ip on ASA no firewall (VPN site to site on SAA) configired no proxy, icmp not inspect, no chance

  some help me

  (Q) ping remote ip unable on ASA is not Firewall not on pc (VPN site to site on SAA) configired no proxy, icmp not inspect, no chance

  Note - I can ping PC but not the same subnet ip on ASA2 L3

  PC---> > ASA1 - ASA2<>

  Hi Matt,

  Let me answer your question in two points:

  • You cannot ping an ASA on another interface other than the one where you are connected to the ASA of.

  For example, ASA1 and ASA2 are connected through their interfaces 'outside '. ASA1 (or any other device on the external interface) can not ping/access ASA2 on his (ASA2) within the interface. The only time wherever this can be substituted is a tunnel VPN with the command "access management" configured for other interface, for example management-access inside

  • Traffic ASA1 ping to a remote client behind ASA2 won't over the VPN tunnel and as such is not encrypted. That's because ASA1 will forward traffic based on its routing table that probably this way through its 'outside' interface Except that traffic is allowed with the ASA2 (using the ACL), it will fail.

  We can do on the routers of sourcing our ping to another interface, but it will not work on the SAA.
