Confusion of subnets

• Problem reading video image from the camera IP Axis - confusion of variant data buffer.

  Hi there;

  I am writing a VI for an Axis IP camera.  He went to work, but I need to extract individual video stream images so I can overlay text using the functions of text IMAQ overlay.

  The thing is when I take a picture using the axis dll library (GetCurrentFrame), it returns a buffer size and a Variant representing the raster data.  The data is = 921 640 bytes representing a 40 byte header, and then the 640 x 480 x 3 raster data.  When I run the vi, I get a correct value for the size of the buffer (921 640) so I know it works.

  What don't understand me, it's the video image is placed in a buffer of type variant.   I don't quite know how to extract the raster data of the data type of "buffer" which is a type variant.  My apologies, I'm a bit ignorant in how to handle the types of "Variant".

  Does anyone have a suggestion?

  This is the VI

  Hi Peter,.

  Just to confirm, what IMAQdx version do you use?  You want to get the version 2010.3 since it is the latest version: http://joule.ni.com/nidu/cds/view/p/id/1641/lang/en

  The next issue would be that the Ethernet cameras discover is not necessary and that it is only used for GigE Vision cameras. The VI was named before IP camera support has been added and the name is unfortunately confusing now. In any case, the discovery of cameras takes place in the background and is automatic. The VI list must list your camera. It may be worth trying just to see if the camera appears in first MAX. Note that the IP camera must be installed on your local subnet, so it can be discovered.

  Regarding the examples, virtually none of the IMAQdx examples included in help-> find examples should work.

• problem mapping 2 subnets together

  Network configuration: modem router (192.168.1.0) and host 1 and powerline leading to another room with a second router connected to the wan port.

  WAN port takes a static IP in 192.168.1.0 subnet and this router runs a gigabit (192.168.0.0) subnet with host 2, tell.

  Suppose we have a host of each side.

  My networking seems to work when it comes to web browsing or ping host - on-"remote" - router (however pings host 2 host 1 but not vice versa), but it does not appear as it is, on the network adapter.

  On each side, I see a router only, a globe host and the internet.

  Because I can't see in the other subnet hosts I can't share folders.

  If a homegroup is allowed on a subnet only, how to share folders between two hosts?

  It would make a difference if I put the second network using 172.30.30.0?

  > Is it possible to Exchange files between host 1 and 2, provided that they are on different subnets?

  No - not on the local network.  You will need to use some kind of remote access software.

  > In addition, Router 1 is also a print server, but how do I send a print to host 2, if I can't see and share the > printer?

  You can not. You have to put them on the same subnet (or still use one remote access).

  I find some of your message confused and contradictory (static DHCP, static ip assigned dynamically to host 2).  Unless you have an unusual special need, you make it unnecessarily complicated.

  See the referenced below instructions on how to reconfigure "Router 2' to act as a WAP and switch.  (Unfortunately this model TP Link router doesn't have a configuration item click for this, but it is not too difficult).  The a parameter that could raise an issue is what IP address to enter in step 2.  When in doubt, I suggest you use 192.168.1.200 since I could not find info on the default DHCP range assigned by the modem router and which should be secured.

• Duplicate remote Lan VPN subnets

  Hello Experts,

  I have 2 lans DISTANCE double connection via VPN with the ip address of 192.168.70.X and 192.168.70.x

  We are already working, but I don't know how to add the second that is listed

  exactly the same thing. Not clear how to apply the NAT on my Local router for the second subnet duplicate.

  I found this article but he speaks of lans in double on both sides, and it does NOT

  http://www.Cisco.com/en/us/Tech/tk583/TK372/technologies_configuration_example09186a00800b07ed.shtml

  Is there something similar, but with 2 LAN REMOTE subnets?

  Thank you

  Randall

  Hi, Randall

  As far as I know, you will have to do it on the remote end. The problem is that if you have the same address for example 192.168.1.70 arriving from two sites on the same time on your side VPN device will get very confused as to where the return traffic should pass.

  You can NAT IP source on your local router to a set of addresses 192.168.70.x addresses, but I still think that the VPN device would not be able to determine what tunnel to send traffic down on the way back.

  I appreciate it is not always easy to get the 3rd party to do something, but I think that that's your only choice.

• Subnet ID

  Hello

  Asked me to share a public ip address to one of our business partners, while it can allow access to one of its applications through this public server server.

  I shared my firewall IP. All my internal network is tapped at one.

  Public IP address on my firewall has been x.y.z.173/28.

  Now he did it has helped my subnet id. x.y.z.160 that is to say the same thing and I was able to access my internal network server.

  My questions?

  1 is it allowed the range of my public ip of 161-174?

  2. If he asked that my external ip address what it means was x.y.z.173 (as all my internal network patted me this IP). If he would have allowed 173 only even then my connection would have worked since my internal network.

  3. Although I am not able to ping subnet id how it transmits traffic. Exactly how traffic flows on the internal network. To the best of my knowledge, it was something where internal ip address is translated to the public on the int of the firewall and then pushed to the router lan and its serial(wan something a.b.c.114/30) and ISP thorugh the lying modem (a.b.c.113/30). Whence the role of x.y.z.160 comes.

  I'm a bit confused.

  Reg,

  Sushil

  (1) If your partner has allowed the sous-reseau.160 - your ADDRESS IP will be able to connect. If he allows only 1 IP address, the IP address of your firewall outside interface - you'll be able to connect, anyway that it will work.

  (2) If you want someone to access a server in your internal network behind the firewall you have 2 choices: -.

  -Need leave based on the TCP/UDP port and use the firewall external IP = Port Forwarding.

  -Assign a specific 1-1 external NAT address static IP in your range to specifically allow external to connect users to your server = static NAT 1:1

  I want to erase something for you - IP routing is the result of a PHB = base by Hop. Any routing device must have an idea where a source/destination IP address is in relationship with himself. If a routing devices MUST be connected via IP on the device to the delivery, or connected to a device that knows how to get the IP address behind it.

  Static/dynamic routing - with both you SHOULD always know the next hop = 1 hop away.

• Addition of a VLSM subnet to an existing design

  Hello!

  I'm studying for my CCENT exam and practical this question in the book warning stumble me.  I'm starting to think that it's a typo.

  The problem relates to the addition of a subnet to an existing model.  The current design already has these five subnets:

  10.0.0.0/24

  10.0.1.0/25

  10.0.2.0/26

  10.0.3.0/27

  10.0.6.0/28

  The boss can't decide among five competitors subnet masks to be used for this new next subnet to add to the internetwork.  However, the boss wants you to practice VLSM and plan ID subnet he would use for each of these four possible masks.  It tells you that the new subnet ID should be part of the 10.0.0.0 network, class A, which the new subnet should not overlap with the original five subnets, and the new subnet ID must be the ID of possible subnet numerically lowest (without breaking other rules).  Choose a subnet ID that you can plan to use based on the following mask.

  / 22

  The answer guide says it's 10.0.8.0/22 as the new numerically lower number of subnet that does not overlap with the existing subnets.  However; It's confusing to me because it seems that the correct answer must be 10.0.4.0/22, because it does not overlap with any of the existing subnets and is a subnet of lower than 10.0.8.0/22.

  Let me know if you need more information on this.  Thanks to you all!

  10.0.4.0/22 includes:

  • 10.0.4.0/24
  • 10.0.5.0/24
  • 10.0.6.0/24
  • 10.0.7.0/24

  Who rides with 10.0.6.0/28.

• Confusion of access VPN site to Site list

  Hi all

  I was wondering if someone could help me explain access lists when the configuration site to site VPN tunnels. Basically, I used this guide to create nearly a GNS3 lab to make me understand IPSec etc tunnels.

  http://commonerrors.blogspot.co.UK/2011/09/site-to-site-VPN-CLI-configuration-on.html

  It is this config works and my confusion is on the ACL they use. There is no mention of the internal subnet 10.1.1.1 on US router subnet but Pakistan a range 172.16.x.x internal in ACLs (but no it's external ISP IPs)

  Why it works? This configuration is incorrect?

  With these tunnels VPN site-to-site, what the source/destination IP address ranges should be in them?

  Any help or information would be great.

  Thank you

  Paul

  With the crypto ACL, the source must be the local LAN subnet and the destination should be the Remote LAN subnet. Crypto ACL defines interesting traffic that you want to encrypt remote and local peer.

  The external interface of the router (generally the one with the public IP address assigned by ISP) will be used to encrypt the crypto ACL and is defined by the command "set by the peers.

  Hope that helps.

• How to get several standard via ipsec vpn subnet?

  Dear all,

  I have this scenario:

  A - Hand router

  Cisco 881

  private network: 10.10.10.0/24

  private address: 10.10.10.2

  address: xxx.xxx.xxx.xxx

  B branch office router

  DrayTek vigor 2600

  private network: 100.100.100.0/24

  private address: 100.100.100.1

  sound: .yyy

  C - seat router

  range Cisco 1800 (no access - not mine)

  private network: 10.10.10.0/24

  private address: 10.10.10.1

  D another subnet in HQ

  private network: 10.20.20.0/24

  available in C

  There is a standard VPN ipsec from A to B due interoperability and compatibility between cisco and draytek. the vpn is in place and works very well.

  D is accessible from a C: hole

  #ping router ip 10.20.20.15 source vlan 1

  Type to abort escape sequence.
  Send 5, echoes ICMP 100 bytes to 10.20.20.15, wait time is 2 seconds:
  Packet sent with the address 10.10.10.2 source
  !!!!!
  Success rate is 100 per cent (5/5), round-trip min/avg/max = 52/56/64 ms

  Now, I need reach D from B.

  I configured adding the 10.20.20.0/24 routing via vpn subnet B and tested the connection replacing the cisco 881 (A) with an another drytek vigor 2820; Add a static route in the drytek 2820 (10.20.20.0 via 10.10.10.1) make B able to reach successfully the D with ping 10.20.20.15.

  After that I tried to divide the acl of tunnel and ping in vain 10.20.20.15 d, I noticed a match in acl:

  Router #sh ip access list 101
  Expand the access IP 101 list
  10 permit ip 10.10.10.0 0.0.0.255 100.100.100.0 0.0.0.255 (3298 matches)
  20 permit ip 10.20.20.0 0.0.0.255 100.100.100.0 0.0.0.255 (14 matches)

  I also tried to prevent NAT from D to B without any match in acl after unsuccessful ping 10.20.20.15 d.

  Any suggestion is appreciated.

  Gianluca

  Hanks for the additional info

  So what is happening is the traffic is not getting encrypted, it is hitting the crypto acl but not getting not encrypted

  I know you would have checked it already, but please just check once more the entrance to nat and see if you have a deny for this traffic in the acl, nat

  We need to know why the tunnel isn't coming for this traffic

  could you please confirm wht is crypto ACLs on the other end, that's exactly the mirror image (2 acl), I don't know how the configuration is made at the other end

  give the following debug command

  Debug ip counterpart condition crypto / / if you have several tunnels will do conditional debugging

  Crypto ipsec its debug debug crypto or her (who was never there I think it's a bit confusing)

  one thing you can try if down the tunnel is also an option, just erase this tunnel using cry clear isa his id and disable remote session encryption and bring it and see if it happens

  Finally, given that I don't know how the other end is configured just try this as the encryption, ACLs on both ends

  10.0.0.0 0.255.255.255 100.100.100.0 0.0.0.255

  and the reverse on the other end and now try to brining of the tunnel to the top

• How to combine 2 VCenter with different subnet?

  Hello

  I had 2 x VCenter instance installed in two different subnet, internal production and one for the disaster recovery site, it is possible to make them connected to each other and then implement in the heart of vcenter beat builtin functionality?

  Thank you.

  OK, I'm a bit confused.  You asked previously on vmotion or vcenter or esx hosts?

  vCenter servers can be linked together without having to be in the same subnet.

  Grouping of vcenters will allow you to have a single pain of glass view for the two vcenters and allow you to search your inventory full, but models are managed by the individual vcenters.

• Confused multicast network activity

  I was using the multicast sample included in the installation of the 4 ENTITY, test multicast. I'm confused as to what I should see my resource monitor - network (Win7). I can see the connections to customers playing the live stream, the only problem is that it seems that I send you the full bandwidth to customers. I thought that I would be the server send less bandwidth to each client. My first thought was that, because the clients and the server are on the same physical network that customers were mainly using the server as main seeder. I guess I'm asking how I can see multicasting is working.

  When FMS transmits a stream of data in a multicast group, it becomes indeed a peer in the group.  The IP Multicast is the only exception to this because FMS bind to a multicast address and port and push the stream directly to it.  Because FMS is a counterpart of the group in the merger and level Application (P2P) scenarios, he will share the stream with its direct neighbours.  By default, FMS will grow up to 4 copies of the output stream.  You can adjust this value by changing NetStream.multicastPushNeighborLimit.  If the server and the clients are on the same subnet, you can set the merge data stream type (in the Configurator) and SGF will insert a multicast IP copy and share it as a peer in the group.  Clients on the same subnet will generally get the IP multicast stream, first and share with their peers in the group, who cannot receive data via IP multicast.  Multicast IP can be configured in your network equipment to route the data on additional subnets for more advanced scenarios.

  Bandwidth savings becomes more obvious when you have a very large number of participants in the Group of any display of the stream.  To give you an example, at Adobe, we use a server to process thousands of customers viewing a multicast stream.  To minimize the P2P traffic between offices during these events, we partition viewers in remote offices in a panel appointed to this post.  In doing so, FMS will send about 3 or 4 copies of the flow of this office WAN link, and then it will broadcast between peers in this office.

  In the multicast of the sample player application included with FMS, you can modify the HTML code to enable debugging.  The variable debugging flash is currently commented out.  You can uncomment only and this player displays a button that toggles debug windows.  If you look in the left pane of debugging, you will see a print of NetStream.multicastInfo properties.  You can use these to determine where and how your data are received.

  that is bytesRequestedFromPeers would indicate how derive you from their peers while bytesReceivedFromIPMulticast represents the data that you receive directly from IP multicast

  I hope this helps to clear up the confusion.

• Why is apple tv (4th Gen) using subnet different comcast

  I need to figure out if there is anything special/different regaurding how ATV (4th Gen) made the resolution DNS when wired to a Comcast cable modem only (no wifi and no router)?  I notice that my ATV selects a different subnet when ATV is set automatically resolve IP and DNS.  Example of my Dell PC Tower and Sony laptop automatically use a subnet of 255.255.255.0, but ATV uses the example below:

  67.166.208.26

  255.255.252.0

  router 67.166.208.1

  ATV works great just need to know why to solve network problems not related to my home office network and at home?

  Hello. You say there is no router, but I guess that the Comcast modem is also a router and DHCP server. Are you using IPv6? You use a static IP address?

• Confused about the new iPhone to load

  It seems that online, there are many variations on how to charge an iPhone the first times, we don't know what to believe.

  Historically, I charge my iPhone for a day the first time that I get it or after I got a refurb from Apple. My battery life has always been fantastic, representatives of engineering apply even told to say.

  This time, I couldn't wait to load the device as I normally would. I connected my iPhone to my PC, did a restore of backup and wait for the iPhone to be able to load completely (about 30 minutes).

  Given that I had a lot of things happens, I didn't have the opportunity to "condition" of the battery, charge of the day to the next, or as some reports say that I have to load it only via the provided OEM charger (not PC). Some say that your battery die completely and then get away after the phone two hours before recharging.

  All these 'new' information is downright confusing. And yet, I see Apple suggesting as a result a large part of these 'tips '.

  Any thoughts on pricing?

  There is no requirement to 'manage' load.

  Charge at any time, for any period of time.

  You can use the phone while charging.

  Don't deplete the battery at a low level.

  Another that these steps, no more measures need to be taken.

• How to set the subnet range when you create the wireless hotstop in mac

  Unfortunately there is no setting in system preferences to change this for a reason any.

  If you really need to do this, you must do so through terminal to modify a specific file in a very specific way.
