• Small rectangles showing that separate pages in PDF MultiPage with Capture of Image analysis?

  I'm having a problem of scanning. I'd appreciate it if someone could explain what is happening and show how to avoid it or how to fix it after the fact. I use a scanner large format HP Officejet 7610, a MacBook Pro running OS X Yosemite, v.10.10.1. I use Apple Image Capture app, v.6.6, for scanning software. I'm scanning of some newspapers, with text and photos on the pages that talk about 11 "x 14-3/4" in size. I'm doing a PDF multi-page, each about 10 percent, with a resolution of 300 dpi. Sometimes, when I scan a single page or several pages, one or more small rectangles of scan appear in the PDF file, following a normal page or between pages. In the Acrobat Reader software, this small rectangle looks like a box of small curious, much less a thumb on one side, and when the PDF file is displayed, the small rectangle is printed, too, as if it were a separate page. Why this rectangle is displayed in my scans? Is it possible to not drop it? After that he was a part of a multipage PDF document, is it possible to get rid of him, keeping the rest of the analysis?

  Hey there @Rudyard , welcome

  I read your post on digitization issues you encounter, and I want to help!

  Please try scanning with HP scanning software to see if it happens to the same problems of quality and if so, try the following steps in order:

  1. Mac OS X: how to reset the printing system
  2. Repair disk permissions
  3. Restart the Mac.
  4. Install the driver full features: series e-all-in-one HP Officejet 7610 Wide format full feature software and drivers
  5. Also install the driver Apple: HP v3.0 for OS X printer drivers

• Cisco 1921 & SG500 VLAN and DHCP problem

  Dear all,

  Thank you in advance for taking the time to read this.

  A little history:

  I want to install a project for an athlete, which is unfortunately on a budget pretty tight with a potentially large quantity of network users (~ 200 without public WIFI). I need to separate the 5 groups of users and to give them all access to internet without see each other. 5 user groups also share the same bandwidth to the internet and VLANs must be controlled bandwidth.

  To do this, I had planned to use Cisco devices built-in functions and buy a 1921 Cisco router as a switch of SG500.

  I have configured the router for 8 subinterfaces is internal NIC with 8 VLAN. I also configured DHCP Pools 8 on the 1921 and set up NAT and firewall.

  What I want to do now is have the SG500 to recognize the VLAN ID, I configured on the router (as well as on the switch using the same VLAN ID numbers), and then assign ports to the VLAN on the switch, and depending on where I plug into the switch, the device receives different IP addresses from DHCP.

  However, I can't get this to work. The router works fine, the 'intact' if left switch gives me an IP address from the DHCP server on the IP address of higher network VLAN (I.e. 168.8.0). but I can not configure the switch ports correctly so that it works. I was also confused, is that dhcp pools that I have configured on the command-line command on the router do not appear in professional CP in the mask of the pool.

  Can someone kindly check the configuration of the router and throw some guidance on how I need to configure the Ports on the SG500? I must say that I have had too many nights and I seem to confuse tagging, untagging, to exclusion and prohibiting the ;.)

  I have the router for you here:

  Thanks again and good night!

  W.

  Hi Wolfgang, for the sx500 configuration can be something like this

  config t

  database of VLAN

  VLAN 2-8

  int item in gi1/1/1

  switchport mode general

  switchport trunk allowed vlan add 2-8 tag

  switchport General disable filtering of capture

  For any client that connects must be no tagged coelio

  So if you want a client access port then you should do something like 5 unidentified to this port

  config t

  int item in gi1/1/2

  switchport mode access

  switchport access vlan 5

• Install Firefox 1 time, & all my usual Web pages are missing details, such as the grids. Does not display the box that I'm typing this!

  After installing a new SSD following a failed hard drive and reloading Windows 7, I decided to move from Chrome to Firefox. Now all my regular sites show subtle differences, as if some detail has been missed. A forum I visit is more a grid that separates each topic, etc. the author answers. When I went to ask this question here, that I had to search for the box to type in the question by moving the mouse around until it became a cursor. Formatting is bad compared to Chrome, and some links are hard to find. I tried all the suggestions I can find help and Support.

  Firefox fits Windows themes 'High contrast' differently from other browsers. You can switch to always using styles page, if you wish, even with a high contrast theme. You'd do that here:

  "3-bar" menu button (or tools) > Options > content

  Click colors, and then change the 'ignore colors specified on the page with my selections above' menu drop down to never and OK outside. Pages should appear by using the styles specified by the site.

  That solve this problem, for the most part? There could still be some differences that remain, but that should help you get started.

• An error occurred while renewing interface wireless network connection: unable to contact your DHCP server. Request a expires.

  I use an Acer Asspire One with Windows XP. We have wireless through AT & T Uverse. The netbook has an Atheros AR5007EG Ethernet card.

  A number of things have taken place lately: I had not used the Acer for some time and the battery was dead and would not recharge. I could book until when it was plugged, but could not get on the Internet. I found online that the solution to the battery problem was to download a new bios that worked wonderfully and it is now loaded. Recently, our AT & T router died and was replaced. I put the new WEP keys in two other computers, and they connect to the Internet. I can't connect to the Internet with the Acer. I tried ipconfig / renew and get the error message: "an error occurred during renewal of the wireless network connection interface: unable to contact your DHCP server.» Request a expires. No operation can be performed on Local area connection while it has its media disconnected. "On the tab"Choose a wireless network", it shows my network and said"absorbing the network address"but nothing happens. When I do ipconfig I see that there is no IP address.
  I took the computer to Starbucks this morning, ran ipconfig / renew and she acquired the IP address and I was able to connect to the Internet. I brought the computer home and tried and failed to connect. The IP address is back to 0.0.0.0 and the error message appears when I try to renew it.
  I hesitate to make a lot of changes since it was working with a different network.

• WAG325N, DHCP, and the DSL dynamic IP address

  Hello. I have problems with the implementation of my router, a Linksys WAG325N. My internet connection is DSL. According to my ISP, I have no username or password for my account because my connection uses a DYNAMIC IP ADDRESS. The operator of my ISP tells me that for my WIFI connection all I have to do is to set it to DHCP. That's all. My ISP does not help me because they sell another brand of routers with their DSL...

  My default IP address is 192.168.1.1

  I use to access the control panel of the CIsco modem. No matter what I do, the light of the internet on the router is always Red; the power, ethernet, DSL, and wireless lights are all yellow.

• Server DHCP and NAT Clone Question

  I turned it off and everything seems to be able to connect without it.

  Am I missing something?

  Also, when I turn off clone my pc MAC addy, I can't connect to the internet. (My computer is hard wired to the router).

  What is the clone for and why can't connect without a permit?

• DHCP Snooping

  Scenerio:

  As part of a modernization project of tech in a big campus and because of several problems caused by users (l) connect the routers on the network and causing DHCP issues, I'm looking to turn on DHCP snooping. During the tech switches access update will be updated first and then the kernel. The new access switches are 4510R + E/Sup7, running the latest IOS XE base license and just passing through. New carrots are 6509 Sup 720's configured as a cluster VSS, manage all routing for VIRTUAL local area networks and have the statements of support IP. The DHCP server which takes care of all the VLAN is a Windows 2008 server that is directly connected to the base.

  I also read all the info I could find on DHCP snooping, but I'm still a little fuzzy on if it changes the way that the DHCP server handles requests.

  Issues related to the:

  • Because the access switches pass only, they only need monitoring DHCP enabled (in the world and on VIRTUAL local area networks) and their uplinks to the core set as being approved, right? In particular, they only declarations of support IP or Layer-3 interfaces for all of their VIRTUAL local networks, right?
  • While I understand that DHCP snooping will be ineffective if it is not lit on the kernel, there is no reason I can't deploy it first to the access layer without touching the basic configurations to avoid large amounts of documents of change control, right? Then, when the kernel is put at level and DHCP snooping successfully activated that will work.
  • I got that on the layer to access the switches uplink to the core are approved, but I'm not 100% on the question of whether the same interfaces are approved on the carrots. I don't think but want to be sure. Carrots of course trust the real interface on that server DHCP is plugged
  • The most confusing part is all the stuff from the Option-82. As near as I can tell its option for the server to use the information from the Option-82. I think that if all I do is enable DHCP snooping on worldwide and on the right VIRTUAL LANs the DHCP relay between the core and the DHCP server will continue to work as it is today, is that correct?

  Is there really this traps or in my case I really just need to turn it on in the world and by vlan, trust the uplinks on the access switches and the DHCP server on the kernel interface and call it a day?

  Thank you

  Hello Nathan,.

  Given that the access switches are only switching, they only need DHCP snooping turned on (both globally and on the VLANS) and their uplinks to the core set as trusted, right?

  Fix.

  In particular they dont need IP helper statements or layer-3 interfaces for all of their VLANS, right?

  Fix. The statement of support ip address would only be necessary if switches performed routing inter - VLAN and the DHCP server is located in a VLAN different.

  While I understand that DHCP snooping will only be marginally effective if it is not turned on on the core, there is no reason I cannot deploy it first at the access layer without touching the core configurations to avoid large amounts of change-control paperwork, right? Then when the core is upgraded and DHCP snooping properly enabled it will work. 

  To my knowledge, the opposite is true. DHCP Snooping is a service of access protection layer - is it not in the core of the network. It has nothing to protect in the kernel once DHCP messages have beein properly disinfected at the edge of the network. For some inexplicable reason, many people think that the DHCP Snooping should be enabled on the network. The fact is that the DHCP Snooping protects against

  • DHCP messages are sent to ineligible devices
  • Ineligible devices posing as DHCP servers

  From this it naturally follows that it is the limit of the network, or the layer of access, where such protection is the most effective. So in your case, I believe that the activation of the DHCP Snooping only on the access layer is actually what you want to do.

  I got that on the access layer switches the uplinks to the core are trusted, but I am not 100% on whether the same interfaces are trusted on the cores. I dont think so but want to be sure. Of cource the cores do trust the actual interface the DHCP server is plugged in on

  If you enable the DHCP Snooping on the basic features and uplink between the access switches and core would have to be configured as confidence both on the basic switches and access. Otherwise, the base ports would pass DHCP messages received from customers because the access layer switches running DHCP Snooping insert DHCP Option 82 in the DHCP messages sanitized and ports untrustred delete all DHCP messages including 82 of the present Option.

  2960 Configuration Guide to

  http://www.Cisco.com/en/us/docs/switches/LAN/catalyst2960/software/release/12.2_55_se/configuration/guide/swdhcp82.html#wp1078853

  The switch removes a DHCP packet when one of these situations occurs:

  • Comes from a packet to a DHCP server, for example a DHCPOFFER, DHCPACK, DHCPNAK or DHCPLEASEQUERY package, outside the network or firewall.

  • A packet is received on an interface that is not reliable, and do not match the source MAC address and hardware address of the DHCP client.

• The switch receives a message DHCPRELEASE or DHCPDECLINE with a MAC address in the DHCP snooping database binding, but the information in the database of linking interface does not correspond to the interface on which the message was received.

• A DHCP relay agent sends a DHCP packet that includes a relay agent IP address which is not 0.0.0.0 or relay agent transmits a packet that includes information of option-82 to an untrusted port.

As I have indicated, however, I personally discourage running DHCP Snooping on the basic devices - I see no reason for this. Please correct if I am wrong!

The most confusing part is all the Option-82 stuff. As near as I can tell its optional for the server to use the Option-82 information. I believe that if all I do is turn DHCP snooping on globally and on the right VLANS the DHCP relaying between the core and the DHCP server will continue working just like it is today, is that correct?

LOL, my favorite on the DHCP Snooping things is the Option 82 interesting how much this topic brings confusion...

The Option 82 was created to provide DHCP relay agent the ability to identify itself and the customer who sent the original message from DHCP unmodified. The DHCP server can then use this information to perform certain policies of customer trust. The format of the Option 82 is not strictly specified, only its basic structure is fixed. You can read more on this and the whole reason to be in the RFC 3046. One of the key points to remember here, however, is that the DHCP server may or may not recognize the Option 82, but apart from that, to copy the value of the Option 82A received in the message to a DHCP client for all its replies sent to this client.

DHCP Snooping uses the Option 82 differently. He didn't expect and doesn't require that the DHCP Server includes the Option of 82 or manages a special way. The Option 82 is inserted by switches access performing DHCP Snooping and it contains two important parts:

• The Circuit ID that identifies the port to which the client is connected (VLAN and the location of the physical port in a switch)
• The remote ID that identifies the access switch to which the client is connected (by the MAC address of the switch)

See http://www.cisco.com/en/US/docs/switches/lan/catalyst2960/software/release/12.2_55_se/configuration/guide/swdhcp82.html#wp1105589

Now, when an access switch performing DHCP Snooping receives a message from DHCP client on an untrusted port, this will happen:

• The switch will insert the 82 Option in the message of the DHCP client. The Option 82 will identify the specific switch and the port to which the client is attached
• The switch will forward the DHCP message according to its MAC address of destination (i.e. in a completely normal way)
• The server receives the DHCP message containing the Option 82. It is not relevant for DHCP Snooping if the server takes into account the value of the Option 82. However, when the server replies, it will insert the original value of the Option of 82 to the answer.
• Access switch will finally receive the DHCP response. Looking at the Option 82, he knows exactly in which port is the message transmitted to the customer - and only the customer - even if the answer was broadcast!

Note that the Option 82 contributes enormously to identify exactly the access switch and its port where the client is attached. If other switches with DHCP Snooping has received this DHCP message (in reason of the flood or address broadcast requested by the client), they would pass this message because they understand once glancing at the 82 Option that the customer is attached elsewhere. The 82 Option allowing to ensure DHCP communication between a particular client and the DHCP server doesn't leak not to other customers.

There is a hunt for witches, associated with the Option 82. A switch run DHCP Snooping inserts the Option 82 messages DHCP clients. However, each DHCP message contains a field named GIADDR where the IP address of the relay agent is registered, where the DHCP message was relayed. Clearly, when a DHCP message goes through a switch DHCP Snooping, it is not relayed (drawn from one VLAN and rerouted to another), so an access switch does not change the GIADDR that remains set to 0.0.0.0. However, at least the implementation of server DHCP Cisco IOS performs a validation on a test received DHCP messages and it drops DHCP messages containing the Option 82, but which the GIADDR field is set to 0.0.0.0 (i.e. unitialized). This can be seen in the output of the debug ip dhcp server packet :

Router# debug ip dhcp server packet

*Sep 9 01:59:40: DHCPD: inconsistent relay information.

*Sep 9 01:59:40: DHCPD: relay information option exists, but giaddr is zero

Under normal circumstances, such a mental health check makes sense - how is it that a DHCP message contains the Option 82 (i.e. the Relay Agent Information Option DHCP) when there is no DHCP relay identified in the GIADDR? However, with DHCP Snooping on the access layer switches, DHCP messages are normal and expected. Therefore, it is essential to disable this check of mental health on the Cisco box that is running the DHCP server configuration using global ip dhcp relay confidence all information or only is selected routed (i.e. L3) interfaces with command level interface ip dhcp relay reliable information.

To summarize:

• The 82 Option is A Good Thing (TM) because it allows to deliver DHCP messages only to the client for which they are intended. Any suggestions to disable the insertion of the Option 82 on access DHCP Snooping Switches are useless 82 Option is inserted by DHCP Snooping Switches in DHCP messages by default - no additional configuration is necessary.
• Through the easiest way - when you deploy DHCP Snooping, does not initially change anything about the Option 82. Make sure that your customers can receive their config IP via DHCP. If yes then there is nothing to resolve. If not, go further.
• If you run a DHCP server on a Device IOS base (router, switch), you may need to use the command ip dhcp relay information confidence-everything (global config) or ip dhcp relay reliable information (level interface) to allow the DHCP messages with the Add Option 82 and unitialized field GIADDR to be accepted. These commands are required only on the device where the DHCP server is running, not on the access layer switches. You may want to first perform debugging as I suggested previously, and only if you see that packets are dropped, add these commands to the configuration.
• I don't know if these commands should be added also to a DHCP relay function efficient switch - I can check that tomorrow in a laboratory.
• If you are using another DHCP server you have to try experimentally whether happy with the DHCP messages with 82 Option present and unitialized GIADDR field

Sorry for the long answer... I hope that I do not bore you to death. We invite you to ask for more! I'll try to be more concise next time

Best regards

• Proxy DHCP does not

  I have two WLC 4402 interview several SSID. Each SSID is a VLAN different with a different IP subnet.

  Now, I want to use a single server DHCP for the SSID. So I set up the server (I code applications for different networking option 82), put him in the VIRTUAL LAN where the PA-manager and resident on and configured management interfaces address of the interfaces on the WLC DHCP server suitable for the new configuration.

  Now my problem: no request arrives at the server level. Now, I tried almost all the options, but without success.

  I discovered that the relay works if the DHCP server is on the SAME subnet. Then all queries are relayed (Yes, relayed, monodiffusees by the controller).

  Debugging DHCP from the WLC says:

  Op DHCP received BOOTREQUEST (1) (len 313, port 1, encap 0xec03)

  1 - relay DHCP selection control block parameters: dhcpServer: 10.22.72.3, dhcpNetmask: 255.255.248.0, dhcpGateway: 10.22.72.33, dhcpRelay: 10.22.72.1 VLAN: 22

  DHCP selected relay 1 - 10.22.72.3 (address local 10.22.72.1, gateway 10.22.72.3, VLAN 22, port 1)

  DHCP forwarding DHCP REQUEST (3)

  ...

  So now I enter the address of the DHCP server on the new server (accessible directly but the ap amanager and management of interfaces) I get the following:

  Op DHCP received BOOTREQUEST (1) (len 308, port 1, encap 0xec03)

  1 - relay DHCP selection control block parameters: dhcpServer: 0.0.0.0, dhcpNetmask: 0.0.0.0, dhcpGateway: 0.0.0.0, dhcpRelay: 10.6.72.1 VLAN: 640

  1 DHCP relay selected NONE

  It just seems to ignore the address of the registered DHCP server.

  I tried several versions of the software (v4.2, v5.2), anyway.

  Proxy DHCP is turned on - as mentioned, if the DHCP server is on the same subnet, it works fine.

  Any suggestions?

  OK, so the DHCP server doesn't have an entry door, so may not respond to a request on another network. That's the problem. With this config you would never get DHCP works, that you saw.

  Not the WLC will not send the DHCP request for x vlan on y vlan... DHCP must be accessible...

• SGE2000 relay DHCP problem

  I'm looking for more help with DHCP relay on a switch SGE2000.

  I have configured the two VLAN on the switch, (192.168.10.x/24) VLAN2 and VLAN3 (192.168.9.x/24). I have the Layer 3 switch. I configured the 192.168.10.4 DHCP and the DHCP Interfaces like VLAN3 relay server. All static IP Routes have been generated by the switch.

  If I put a client computer on a port which is Untagged VLAN 3 and try to get a DHCP address from the server on a port that is not tagged VLAN 2 I never get a response.

  I made a few captures package and here is what I found:

  1. I see the DHCP on the client computer
  2. I see the DHCP Request to the DHCP server from the IP shown in the switch to VLAN 3 (192.168.9.254)
  3. I see the server DHCP responds with a DHCP offer
  4. The DHCP offer never gets the client computer

  I can't get a DHCP address to any system not on the same VLAN as the DHCP server. 82 option is disable, and tried him, that made no difference.

  Any help would be great.

  Thank you

  Phil

  Hi phil,.

  Have you created a static route on the DHCP server that points to the network 192.168.9.0/24.

  The entry door for this network, in the perspective of relay DHCP servers, is the IP address of the switch SGE2000 VLAN2.

  I think that if you tried to ping to the IP address of the switch VLAN3 with the DHCP server now, you will not get a response.

  When you create a static route to be persistent in the DHCP server, you should then be able to address IP VLAN3 ping of the switch.

  Best regards, Dave
