Question realted anti-spoofing feature on PIX

(1) is there an anti-spoofing feature on PIX firewall?

(2) if it is respected, how are they implemented? It is being implemented by default? And how do you control the anti-spoofing rules?

(3) if it is respected, is they are implemented at layer 1 or 2, or only at the level of the layer 3 (IE RPF of the CBAC and access-list)?

Hi, I would like to give one of these:

(1) the only spoofing that PIX offer short configuration to block addresses RFC 1812, inside addresses, access networks bogon lists, etc. is to configure path reverse unicast. Have a look here:

http://www.Cisco.com/univercd/CC/TD/doc/product/iaabu/PIX/pix_sw/v_63/cmdref/GL.htm#1053009

(2) RPF is not implemented by default. You must configure this if wanted.

(3) layer 3 only.

I hope this helps.

  • Question regd import/export feature of CUCM BAT

    Hello

    We have a production cluster CUCM 8.6 running.

    I was asked to create models of translation of 300-400.

    I see that I can not do this directly through bat. But I can't see the import/export option.

    We have 1000's of existing patterns of translation on our system.

    I have a small question about the import feature.

    A new import overwrites existing data in the database that contains the data in the import file or because the new data in the import file added to the existing data.

    If the import file has only the new models of translation, it will eliminate the existing patterns of translation in the system?

    I don't have a system of cucm lab to verify this behavior?

    Can you please help me on this query?

    Thank you

    Pete

    I often do and it's the only way to bulk add translation models. It removes all the reasons for translation it will only add/edit the translation model. If all the new models it will simply add your new entries.

  • Consider purchase of Wacom Cintiq 27 HD Touch - Questions about the tactile feature in Photoshop and Lightroom

    I'm considering buying a 27 HD Touch of Wacom Cintiq monitor. I have a few questions about the two programs Adobe and their use of the 'touch' feature - Photoshop CS6 and Lightroom 5.7 running on Windows 7.

    1 problems related to touch a feature in Lightroom and Photoshop CS6 and 5 resolved that you see on the forums of Wacom a year ago?

    2. If so, is there sufficient value gained through the tactile feature in Photoshop CS6 and Lightroom 5 to justify the $500 price difference between the Cintiq 27 HD vs Touch HD? (I realize that this is a subjective question based on the abundance of its cash).

    3. I intend to stay with CS6 as long as possible to avoid a monthly subscription, BUT I wonder if buy the Touch HD can provide additional key features in future releases of these products that do not exist currently. (It is a pie in the kind of sky in question).

    Thank you!

    Support for Photoshop Touch is added by CC 2014.2.2.  However as the Pro Intuos Wacom tablets with touch can be used with earlier versions of Photoshop and the Wacom Tablets Configurator can custom features can be used with Photoshop touch tablets.  I use LR but I don't know that the same thing would be true for her. You can configure the setting for many applications. The device driver knows which application its interfacing with and uses the parameter set for each...

    I have disable most of touch when using Photoshop.  The main reason why I have a Tablet is Photoshop Brush tools. Like Eraser, clone stamp, etc, nothing is better then a pen when it come to create the layer mask.  For most programs, I always use a mouse and I use the keyboard, the mouse and the pen with Photoshop...

    I never wanted a Cintig I do not have my hand between my eyes and the work. I'm not an artist.

  • Satellite C660D-181: Questions about the 3D feature

    Hi guys, I'm new on the forum, but not for Toshiba laptops,

    I bought my girlfriend Toshiba C660D-181 earlier today, and myself, I think it's a great phone for the price. Especially the amount of Ram
    and the graphics card.

    One thing I'm confused is part 3D Capable.
    What is meant by 3D Capable, that it allows to me? Do I need additional equipment?
    I have no idea how to use this feature, or what he actually did. I know that 3D capable means generally (although on 3Dtv) that you can view a 3D with glasses content.
    But exactly how it works, if so, on this computer?

    I'm a little confused about that to be honest, and any help will be greatly appreciated.

    Thanks in advance!

    Hello

    The laptop is equipped with the AMD Radeon HD 6250 graphics card.
    This graphics card supports 3D graphics accelerator and a 120 Hz 3D, Toshiba TruBrite HD, LED backlight display.

    This means that the screen is 3d compatible, so you can see on the screen with DLP 3D or polarized or shutter (all are rare and special) drinks.
    Therefore, the laptop is 3D ready.

    You will need these glasses to watch 3D content.

  • Questions about math broadband features

    Hello

    I'm just trying to understand what advandages High Troughput Math Funtions have. I so ask a few Questions.

    I always talk about beeing inside a SCTL.

    1. in the Image you can see four functions to add. One with U32 who must use more resources than with the U16Datatype that uses mor than the U8. But my broadband Math FXP uses fewer resources than the U8 Version?

    2. who this four functions add will take less time for execution?

    3. If I add two 32 bit a number with the normal add-in and the other with broadband Add. Which functions uses less resources and who will be fastest?

    4. How would it bee if I had a Multiplication instead? When I understand the concept of a Multiplication on the right it will be done with a DSP48E. This logical block is able to multiply a little 25 number with a number of 18 bits. So the U32 multiply will use 2 DSP48Es and the other three functions would use a DSP48E.

    I guess that the U32 Version will be slower enforcement?

    Whats on the other three will be their equal execution speed, or Versions with smaller data types will be faster?

    With greetings

    @JLewis: thank you for your answer it helped a lot to understand functions HT!

  • Anti-Aliasing feature in graph does not always, but inexplicably...

    I noticed a strange bug of Aliasing in the graphical indicator in my labview 2014

    I have attached a file that has two supposedly identical graphics but on my PC (windows 7, i-3 dual core, 8 GB Ram) charts two different display modes.

    The one labeled "aliasing problem" is jagged when anti-aliasing is turned on and when is broken. The other table behaves as I expect and I'm used to.

    (1) - does anyone see this difference as I do?

    (2) can someone explain the reason for this phenomenon?

    much obliged for any comment

    Thank you

    I see the same thing:

    There seems to be a bug specifically with the graph of scan (with the line). Power off the line, updates work fine. Also, turning aliasing seems then redraw the map with the correct folding (you can see that at Midway through the data on the first plot). You could try periodically calling the method "Force redraw' to see if that makes aliasing to update. It seems also set when you stop the VI.

    Weird bug since it is only on one of the graphics.

    (Also... What is with all the local variables and signalling of the value? (And the weird to leave timeout?)

  • Questions about HR server features

    Hi users of Adobe.

    We are considering to recommend RoboHelp Server as a publication to a customer. They are already using RoboHelp and want to make content available online. Another problem is the centralized management of their content help documents. I would be very happy if someone could answer the following questions:

    Is it possible to integrate the HR server with a CRM system or another user for authentication management system? It can be integrated in a single authentication infrastructure?

    How does the mechanism of access control? Can I set permissions that is allowed to publish some documents/projects?

    It does support workflows (review/accept/reject)? Or is this done using the staging server?

    Support content versioning? Or do we need HR SourceControl for that and more?

    It supports locking (Express check-in, departure) documents to allow simultaneous editing?


    In short - RoboHelp Server is as a document management system, or the authors do store the content on their local computers and publish only the final version? Another problem is the management of translations - authors may publish a single version of language, which is translated by others (other countries) and published on the same server?

    Thank you very much in advance for any help!

    Andreas Hartmann

    Wow, Andreas. Welcome to the Forums.
    This is a list of laundry!
    The answers are about, 'yes', if I understand correctly. That said, I don't know that a lot of GCD, so your mileage may vary.

    To start, you can take a look at my article on the Adobe Developer Network site for an overall vision.
    Adobe RoboHelp Server 6 improves the feedback loop

    I discovered RoboHelp and RoboHelp Server as a "content management" rather than a "document" management system even though it's kinda semantics. Using variables, labels compilation conditional and single Source layouts, you can manage the content of your release in a quite specific way (including issues at certain level, your translation).

    In other words, a team of multiple authors can manage the content of a Web site in the way you describe with a combination of:

    1. the customer of creation (main application of RoboHelp) to develop the content and manage.
    2 RoboSource Control (for the check-in, check-out and versioning you mentioned) where creating content source material is stored on a central server for backup and access by the team.
    3 RoboHelp Server to manage authentication of who has access to the web server for editing, etc. RoboHelp Server is an application of Active Server Pages running on IIS, usually with a MS SQL Server or Oracle DB as primary server. Therefore, it uses Windows Server simple authentication methods. When you configure the author to publish on the server, it will ask you for the username and password. Once this is configured, it is seamless from there. This login/password can be the same as what do you call your pair of SSO, as it is meets the Windows Server schema mentioned previously.

    RoboHelp author who can be designated as the 'privΘ' of the team can create and assign permissions from the client to create and manage the remote site server without having to pester the Web administrator for the maintenance of the site.

    The intermediate server scenario you mention is an option that is entirely up to your team and the people in IT. RoboHelp Server don't care one way or another. It is just an application sitting on an IIS web server. This server can be the 'development' or staging server or the so-called 'production' or the live server.

    The different languages you mention could be published on the same server and mixed in a single site (type of disorder) or you might have different language sites (as long as they are different domains/IPS) permit to RoboHelp Server sitting on the same machine.

    About the language, an important element in the search is the RoboHelp version you are using and it is supported language. The long-awaited Adobe RoboHelp 7 (currently in beta) and expected "before the end of the year" will have full character support Unicode/double byte for 35 languages and a wonderful way to manage translation workflows.

    Well, which should help you get started. Let me know what I missed!
    Thank you

  • VPN on PIX Newbie question

    Hello

    I need to create a site to site VPN, I have in mind a PIX 515e. Behind it is a network of win2k with a domain controller for authentication. Users of the remote site must be attached to authenticate to this DC via a VPN.

    The two sites to connect to the internet by modem cable and the remote site will have up to 10 users behind the PIX/VPN.

    Here are my questions:

    What kind of material PIX the remote site needs? A 501/506, or something else.

    Do I need a VPN concentrator, etc. to the head of line?

    How the hell i make it work?

    Sounds simple right? I appreciate a lot of help because I am a little confused. Thanks in advance.

  • Questions about new HA in vsphere features 5

    Hello!

    I have a few questions about new ha features in vsphere 5

    I found, there is a master ha in the cluster that monitors other hosts and protected virtual machines through two type of heartbeats (network and data store) and move the VMS if necessary. If this host fails, an election is held and new master ha is determined by vcenter server.

    Ok! What happens if we install vCenter Server as a virtual machine inside the host who is the master ha in a cluster. If this host fails (something like a power cut) its agent goes too far and also the vcenter is destroyed. So, who's going to hold the election and introduce the new ha so that the old ha and vCenter are out of the game.

    I know that ha staff are not entirely dependent on vCenter and runs if the host taking vcenter is far (restart vms including vcenter or moved to another host on another) but I think this one is different because of the new role of master

    My next question is on the different types of events, which can arrive at the slave of the hosts and do their partitioned or isolation. I'll ask them later (once this question is answered

    Thanks to you all

    you mean master election (who needs to know the host object id in the cluster and the number of data warehouses connected and...) is performed by agents themselves? and he needs no intervention vcenter?

    No fix - no intervention from vCenter for an election of master.

    and another thing. When the host with vCenter machine on it and the role of chess master, how other officers find that the master is absent? is not the work of vcenter to notice and say to others when master does not work?

    Is not work of vCenter - is the work of the master and the process of hearbeating among the slaves.

    what I doubt is that: If slave hosts loose connectivity with the master, they think that they are faulty and should present themselves as isolated or partitioned and it is the duty of the vcenter to know when the captain does not work! can you please correct me here

    See above - is not vCenter work to determine which node is failed or isolated - it's the work of agents FDM.

  • Claire do not fragment Bit - PIX

    I realize that IOS has the ability to clear the df bit but it the PIX has this same feature? I am currently working with a Netscreen counterpart which has a much larger pool of "tweaks" at its disposal that I noticed on my PIX PIX OS 7.2 535. My issues are with anti-replay and I can't even turn off the anti-replay feature without disabling IKE, and we can not all our peers VPN manual configuration.

    My basic question is if you clear the df bit is possible on the PIX?

    Thank you all for the research/sponsor.

    Chris,

    Yes, it is possible to erase the bit df on the Pix to IPSEC Tunnel in version 7.2.

    The command is:

  • Number of antennas router question?  (Several gadgets WiFi using 1 router)

    -My House is a 3 storey 5 bedrooms single family home.  There are 4 people living under his roof and each person has at least 3-4 items wireless who rely on our network domestic wi - fi.  Include wireless iPhone 2 of 6, 3 iPhone 5, 2 iMac (an older and a new one), 1 airbook, 1 MS Surface, 2 older laptops Apple (the old 1 "thick white), 2 iPads, Kindle 1-2, frame 1 photo wireless, 3 printers, wifi, 1 Sony PlayStation4 (via wifi) and much more.

    Our current router is a double (2.5 and 5) and we use them both, and we had recently a technician change the channels, so we are not in competition with the neighbors.  The router signal strength is strong in the home to most of the places.

    My question: with so many features, would be useful to have several routers with multiple antennas to accommodate this request, or made this same question?

    My current router has 3 visible external antennas.  I read that the Airport Extreme has 6 internal antennas.  I'm ready to go buy Airport Extreme, if 3 additional antennas can help, or if I can use two routers for a total of 9 antennas (if this is important).

    Our services to wide band is xfinity and we have one of their fastest options.  Not quite the 105, but about 80.

    Any suggestions?

    Several wireless routers will tend to work better than the Gothic pulpit super multi-antenna a monster looking for router.

    But they all need to be connected with the ethernet.

    Read how to get excellent wireless in your House.

    http://www.SmallNetBuilder.com/basics/wireless-basics/31576-the-best-way-to-get-ensemble-Maison-sans wire-coverage

    External antennas tend to be more effective than internal, but the actual number of antennas is easily overrated.

    Most of the antennas used on routers now are dual band... which means inside the plastic, they have sections for the two bands... If an antenna is really two.

    Our current router is a double (2.5 and 5) and we use both

    Is what model exactly? Of basic etiquette please.

    We had recently a technician change the channels, so we are not in competition with the neighbors.  The router signal strength is strong in the home to most of the places.

    It would have been correct for the first 5 minutes after the technician left the House and then totally out of place. Channel of all the equipment that surrounds you change every day, every hour... maybe every 5 min. While I don't disagree with fixing channel... others would say that it should be left on auto. You gain nothing much at all.

    If the signal strength is good over a 3-storey house, you are incredibly lucky.

    You can't effectively add routers more unless you install ethernet to provide an infrastructure for data streams.

  • Question about Junkstore

    We have a Sonicwall TZ with the anti-spam Service.  I see that I can log the Sonicwall and manage the junkstore, such as the removal of enamel from the Junkstore or unjunking points.

    I would like to pass on the management of junkstore to someone else, but don't want to give them access to the Sonicwall device.  Is it possible for someone to connect to the junkstore through a web browser, or otherwise, to manage the junkstore?

    Also, on another issue, when I delete the email from the junkstore, is that way 'teach' the sonicwall what is undesirable?  Or is that not necessary / is not an option?  I was wondering how Spam services learns what is undesirable for us?

    Thank you

    If you give admin access to the firewall, they can manage the junkbox as well.

    There is no way to limit them to only access the junkbox or anti-spam features.

    The software or complete Email Security appliance allows this kind of access restriction and you can assign users to different roles.

    The judgment of what is spam is made by cloud servers and you can contribute in any lack in installing junk mail to outlook button that is available in the download section in the anti-spam settings.
