• The EA8500 supports DHCP Option 60/61?

  Hello

  I was wondering the EA8500 can be used with sky fiber Pro service to the United Kingdom? Obviously I would need to extract the username of the SR101/102 and then intend to use the modem Openreach VDSL2 with the EA8500 (btw brilliant router) but after some research, I understand the router needs to support DHCP option 60 & 61 in order to connect with the sky. The EA8500 does it take?

  See you soon

  Linksys engineering has notified me that the EA8500 is not compatible DHCP Option 60/61.

  Filed a feature request in support of these DHCP Options. Lets hope it is approved and included.

• DHCP option to set the controller IP for Access Points (Airespace)

  Hello world.

  Does anyone have an idea to specify the controller using DHCP options.

  We use:

  -Controller AIR-WLC4404-100-K9

  -AP-1010-AP-5312 poinst access

  -Server dhcp DHCPd ISC 3.0.1

  Newspapers on DHCP server indicates that access points become the IP addresses, but the controller information are not "read" / "included".

  In the productive environment, controllers will be redundant.

  So far, we couldn't sucsessful with eighter of these configurations:

  Block i. using VTL:

  http://www.Cisco.com/en/us/products/HW/wireless/ps430/products_quick_start09186a00805100f5.html#wp49287

  subnet 10.50.107.0 netmask 255.255.255.0 {}

  option subnet-mask 255.255.255.0;

  routers option 10.50.107.1;

  option domain-name-servers 10.20.51.11, 10.20.51.12;

  option vendor-class-identify Airespace 1200;

  the option dhcp-client-identifier 0xf1, 8, 10.20.51.254, 10.20.51.249;

  DDNS-updates

  DDNS-rev-domainname "in - addr.arpa.";

  DDNS-domain name "xxyy.local.";

  default-lease-time 28800;

  range 10.50.107.101 10.50.107.200;

  }

  II. using the DHCP Next-Server option:

  subnet 10.50.107.0 netmask 255.255.255.0 {}

  option subnet-mask 255.255.255.0;

  routers option 10.50.107.1;

  option domain-name-servers 10.20.51.11, 10.20.51.12;

  Next-server 10.20.51.254;

  III. use of Header Information Option 43 described such in DHCP Manual:

  WLAN-apc code 60 option = text;

  ip address wlan code option 43 = controller;

  subnet 10.50.107.0 netmask 255.255.255.0 {}

  option subnet-mask 255.255.255.0;

  routers option 10.50.107.1;

  option domain-name-servers 10.20.51.11, 10.20.51.12;

  option wlan-apc "Airespace.AP1200"

  option wlan controller - 10.20.51.254;

  IV. using header to the DHCP server information:

  class "-classes of suppliers ' {}

  vendor-class-identifier option match; }

  {"Airespace.AP1200" subclass "-classes of suppliers '}

  Next-server 10.20.51.254;

  }

  Does anyone have a working (using the SAI?) configuration or advice?

• Question of DHCP Option 50

  I understand that the DHCP 50 option is for the customer asked the IP address.

  I have 3 questions about this...

  1. the DHCP server on the router maintains the MAC--> IP mapping during 24 hours right?

  What happens if I ask a non assigned a different IP address in the 24 hour window? My request will be granted each time?

  What happens if I ask for an IP address not assigned different after the 24 hour window? I guess that my request will be granted every time in this case.

  2. always in the window of 24 hours, if the requested IP address is leased to another network device, but the device has long been disconnected,

  I get the requested IP address?

  2 do all versions of routers support this option?

  Depends on the implementation of the DHCP server. The RFC does not say how to handle 50 option. The DHCP server can but should not affect the requested IP address. It can completely ignore this option.

  So:

  How long the server retains the mapping? Depends on the server. It may or may not remove the mapping after the lease has expired (which I assume is the 24 hours, that you reference).

  Ask a different IP address during the valid lease? Depends on the server. The server may grant each time. Another server can refuse each time.

  I think it is more common to not to grant the request. Internally the DHCP server manages static IP mappings and pool all the same except the static IP mapping has an unlimited lease duration. As long as a request from a computer comes that already has a mapping (static or pool) he always attributes known IP address and the other does not.

  After the expiry of the lease? Depends on the server. A DHCP server keep the maps even after the expiry of the lease. The simple purpose of this is that if you have a fairly large pool that gets not exhausted you basically assignments to static IP addresses to DHCP clients. Even if a client releases the lease (because the computer is stopped) or the lease expires, he will always keep this information. Next time (for example, you turn on the computer after the weekend) it will always go to the same IP. But again, it is up to the implementation of the server. Other servers follow other policies and do differently.

  Address IP lease request? N ° never. The DHCP server must not assign an IP address that has been rented elsewhere. There is no reliable way to make sure that the DHCP server as other devices is indeed off. If a unit is stopped, it must release the DHCP lease. If it is not the case, the IP address is blocked until the lease expired. The only case that a transfer could occur is if the DHCP server has been reset and lost its DHCP lease table. In this case, the DHCP server does not know before granted leases.

  Supported? All DHCP servers must be able to receive DHCP requests include this option. It is the implementation of the DHCP server if the DHCP option is really accepted or not. Some servers may completely ignore this option.

• LWAPP AP - DHCP Option 43

  Hello

  I'm working to deploy a group of 1242AG APs with a 12-4402. I'm looking to use LWAPP and run the WC in mode layer 3 with deployed on a different subnet access points.

• Cisco SPA with problem of DHCP Options 66

  Dear all,

  I have a problem of my phone Cisco SPA for the autodeploiement.

  If I manually enter the page configuration and paste "[- pwd - password user uid] http:///dms/def/spa$PSN.cfg" in the profile rule. Everything works perfectly.

  However, we would like to do in the provision of zero touch, I add the "[- pwd - password user uid] http:///dms/def/spa$PSN.cfg"DHCP Options 66. " The SPA phone seems impossible to get the 66 Options parameter. It shows that "/ spa$ PSN.cfg" in the rule of profiles.

  I'm sure that the DHCP server works perfectly.

  Can anyone help on this?

  Kind regards

  Desmond

  You cannot use the custom during initial deployment (zero touch) password. DHCP can be used to deliver key to the device in this way.

  Ok. What are the options you have?

  You my use of the configuration file, compiled with SPC type -target option. It encrypt the file by using the password from each device Mac so you need no password given to the device - device can calculate the password required their Mac. It provides just basic security level - insensitive user, like me, know the algorithm used for password generation so that it can calculate the password and decrypt the file.

  You can use HTTPS with mutual certificate authentication to deliver XML or SPC configuration form. All phones have the unique client certificate, then you can be sure that the request has been issued by the unit. It offers a high level of security.

  There are also a few other possibilities, but disclosed so that information on the goal you want to hit, so I can't list.

  Just note that DHCP will meet anyone, in addition, the answer may broadcast (therefore handed to anyone, even without prior request). If you deliver critical data via DHCP, you can consider them publicly available. Security resulting is without security.

• Microsoft DHCP - Option 43 Setup Server

  I have the scope properly configured insofar as the 241 Option with Option 43 and the VCI in for both the series 1130 and 1200 AP however, how can you do this job if your subnet has 1200 and 1130's inside? Basically if I have two 241 options set, the 1130 comes by first allowing the 1130 s associated, but not the 1200. If I remove the Option 241, the associated 1200 1130. Basically, how can I get both working properly the scope?

  Thank you

  Hi Pierre Roussy.

  Here is some additional info;

  This section contains an example configuration DHCP Option 43 on a Windows 2003 Enterprise DHCP server for use with the lightweight access points. For other implementations of DHCP server, see DHCP Server documentation to configure DHCP Option 43. In 43 of the Option, you must use the IP address of the management interface of the controller.

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

  Note that DHCP Option 43 is limited to a single access point type by DHCP pool. You must configure a separate DHCP pool for each access point type.* *.

• The bytes available always 0 when trying to load the image

  I read a TON of posts here on loading files from the SD card and use the following code:

  try      {         FileConnection fconn = (FileConnection)Connector.open(filename, Connector.READ);          // If no exception is thrown, then the URI is valid, but the file may or may not exist.           if (fconn.exists())           {             InputStream input = fconn.openInputStream();              int available = input.available();                byte[] data = new byte[available];                input.read(data, 0, available);               EncodedImage image = EncodedImage.createEncodedImage(data,0,data.length);             fconn.close();                return resizeImage(image, i, j).getBitmap();          }         else          {              Dialog.alert("File " + filename + " does not exist.");           }    } catch(Exception e) {}
  

  However, input.available () always returns 0. The name of the file that I use is:

  file:///SDCard/MyImage.PNG

  The connection file is opened successfully and fconn.exists () will always return true. Any ideas?

  P.S. Looks like you're just trying to play a file in full using an InputStream. Are much better options: (1) read to the end of the stream (e.g., read returns-1), or (2) ask the file for its length, and then read exactly what the number of bytes (always need to check if read returns - 1).

• RV042 150 DHCP Option

  Hi people

  I have a RV042 VPN router with the latest firmware v4.2.1.02.

  This router is connected to the main site through a VPN Tunnel.

  Now, I want to configure a DHCP Option if I can put an IP phone

  behind the RV042. The IP phone should receive an IP by DHCP

  the RV042 and of course, the IP address of the Director with the

  Option of 150.

  I can configure DHCP and it works fine but I can't find where I

  or can configure Option 150.

  Does anyone know ho it works?

  Thank you for your help...

  Kind regards

  Unfortunately RV042 isn't compatible DHCP Option 150.

• Cannot use the option button to access the folder of bookmarks hidden on a dead drive

  I'm on Mac OSX 10.7.5, and I can easily access the folder on my current drive by pressing the option key (so that the hidden library appears) then get bookmarks of otherwise hidden files (since it's my new boot drive)

  BUT

  I need to copy / move my LAST favorites since ten days previously, a dead hard drive. The drive is usable, just not able to start.

  BUT

  Since this amazing new 'hold option on GO in the Finder menu to see the invisible library feature' (sarcasm) requires your operating system to be started, I can't access the bookmarks folder in the library. How can I do this if the Finder is not started on the dying drive? Is - this make any sense?

• What does the option "copy photos to the photo library?

  I explore this now app Photos (worst name ever) and I wanted to import photos in Photos. The problem for me is I want to let the pictures where they already are. I'm not interested in a database or the system that hides the pictures of me in the finder. I want to be able to right click and reveal in finder - "export image" is a terrible choice.

  So, I see an option to check in the preferences. It reads: "Copy pictures to the photo library" but has no explanation as to what that means or does. This is what it will move my photos if I select copy? (their disappearance from the original file)? It will resume photos - clutter up my drive? If we make a copy and I update the original in Photoshop - it will reflect this change in the Photo?

  So many questions and I can not find an answer to any place. Even the help files had nothing that I could find.

  It reads: "Copy pictures to the photo library" but has no explanation as to what that means or does. This is what it will move my photos if I select copy? (their disappearance from the original file)? It will resume photos - clutter up my drive? If we make a copy and I update the original in Photoshop - it will reflect this change in the Photo?

  Default is 'Copy photos to the photo library' enabled.  Then the pictures will do exactly that. Any Photo that you import pictures is copied in the photo library and managed by pictures. You can remove the original outside the library after you have verified that it imported properly.

  If you disable the option, pictures reference the file in its original location and does not copy it.

  This configuration is not recommended because you have to manage photos on your own. If you delete photos of Photos, you must delete the original outside yourself. You cannot use iCloud photo library with referenced files and if dot nee restore you from a backup library will need films to another drive, you will need to manually reconnect all originals. It is subject to errors.

  If we make a copy and I update the original in Photoshop - it will reflect this change in the Photo?

  It will not work. Two Photos will ignore changes to Photosho or lose the connection to the original file. To use an external editor in pictures use extensions to change Photos photo editing panel. Let the pics to send the original to the external editor.

  This help page explains how the import options work:
