Question on which of these 3 hops traffic would take ?

Regarding the question below, can someone confirm how you determine which route it would take ?
If you write the next hop information in binary to compare against the target route, you have to do that for "via 153.2.220.2", for example ? Is that correct ? That's the next hop info you are looking for, not the "153.2.25.0/23" info.
Question:
If a packet is sent to 153.2.25.66, which next hop it would take ?
S 153.2.25.0/23 [1/0] via 153.2.220.2
O E2 153.2.25.0/25 [110/20] via 153.2.230.2,serial0/0
R 153.2.25.0/26 [120/1] via 153.2.1.1,e0/1

Hi,
The router would use the OSPF route, 153.2.25.0/25, to forward packets to the host 153.2.25.66.
The reason why it doesn't use static or RIP route is because, routing decisions are based on the longest match. The OSPF route covers anything between 153.2.25.0 - 153.2.25.127. Static route covers anything between 153.2.24.0 - 153.2.25.255. RIP route covers the range 153.2.25.0 - 153.2.25.63.
As you can see, the OSPF route is more specific than the static route, which covers a wider range. The RIP route doesn't include the host, 153.2.25.66, in its route at all. Admin distance acts as the tie-breaker only if the route/mask is the same.
I am not sure what do you mean the subnet mask isn't given the /xx after the route is the mask for the route.
Hope this helps!

  • Which of these 2 laptops would be my best choice for editing video?

    I am going to get a new laptop mainly to use for LR and PS but I also want to be able to edit video.  Which of these 2 laptops is my best option...
    ASUS ROG G751JT-CH71
    Intel Core i7-4710HQ 2.5 GHz
    16 GB DDR3
    1000 GB 7200 rpm Hard Drive
    17.3-Inch Screen, Nvidia GTX970M 3GB GDDR5

    1 TB 5400 rpm Hard Drive, 256 GB Solid-State Drive
    17.3-Inch Screen, NVIDIA GeForce GTX 860M
    Windows 8.1, 4-hour battery life
    Additionally, if you feel there is a better choice for $1500 or less, I would love to hear that advice as well.  I would really appreciate your help in making this decision.  Thanks!

    Of the 2 the Asus everyday. You won't notice the difference in the CPU's but you will more so with the GPU's as the 970 is a decent step up from the 860m. Add in extra SSD/HDD and RAM (I believe it goes up to 32GB but check), and see if they have allocated the 16GB as 2x8GB sticks or 4x4GB sticks.
    Other option I would suggest looking at a custom PC builder such as Cyberpower, Xotic or other (no affiliations, heck I don't even live in the same country). You will be able to get a much more tailored system with a better upgrade path within your budget. You will get better CPU, better GPU, RAM options up to 32GB and more flexible drive and msata combinations and most importantly some flexibility with the way the system is configured. Some are re-brands of popular gaming laptops, some are from the more custom line of chassis and some are just tweaked versions of your off the shelf names. Plus you don't have to crack the thing open to replace drives etc. that you are paying for but won't use due to slow speeds and the warranty implications that can come from doing this
    Not saying buy this as you need to shop around and find what suits you best but as an example this is from Xotic.

  • Which of these 3 laptops would you recommend

    Hi,
    I got it down to the final 3 laptops that I like. Which one would you suggests. I'm looking for something that's fast, has lots a hard drive space, good monitor and a blue ray player would be nice.

    All 3 of these machines are solid! My personal opinion would be to get the Toshiba, love the battery life and they just make some great machines. I've never been huge on Vaio's, I feel you pay a little too much for the name. As far as the Samsung goes, I am in love with both Samsung models my store has in stock, only thing I'm unsure about is how they will do. We don't have a vast track record for Samsung and consumer laptops.
    All in all, these machines are all rock-solid but I'd have to lean towards the Toshiba as my personal opinion.

  • Which of these 2 Laptops would be best with Premiere Pro?

    Need opinions between two laptops I'm eyeing as portable options for editing footage from my Canon HF S100.
    Really just want a portable 14" laptop that I can do relatively basic editing AVCHD footage on Premiere Pro relatively smoothly when I'm travelling and some encoding with adobe media encoder.  I don't care about battery life. I just want Premiere to play/edit AVCHD footage without the choppy video stuttering. I'm also hoping for some faster encoding times than my 4 year old current laptop. Both laptops are about the same price. The only major differences is a dual core i7 vs a quad core i7... 4gb of ram vs 6gb... 256mb video card vs. 512mb video card... and solid state hard drive vs. 7200rpm hard drive. Opinions?

    a 17" laptop with a "DESKTOP" i7 and 3 internal drives will perform EXACTLY the same as a desktop with an i7 with 3 internal drives
    (note i didnt mention raid 0 arrays)
    if you dont need firewire for ingest (who does these days)
    then you can use the Express slot and buy a Sonnet Array that connects vis the Express slot.
    making it every bit as fast as a desktop
    the only downside (and more to do with AE is the ram speeds are slightly slower)
    FYI this is the ONLY laptop i think is good enough for video. the newer i7 mobiles are rather slow

  • Which one pricing procedure&pricing type take effect?

    I assign the different pricing procedures to the master data FF.and document type A respectively.
    And the procedures contain multiple pricing types.
    When I entry a sales document with document type A and master data FF.
    which procedure and condition type would take effect? or they take place together?
    thanks

    Dear Humility,
    which procedure and condition type would take effect? or they take place together?
    The pricing procedure will get determine based on these combination
    Sales areaDocument pricing procedure of A document typeCustomer pricing procedure of FF--->Pricing procedure.
    So what is the procedure you have assigned for this combination in OVKK transaction same pricing procedure will take effect.
    What are all the condition types maintained in that procedure all will take effect.But values will come based on the settings you have done for those condition types.
    I hope this will clear for you,

  • Which of these solutions would you recommend?

    while trying to create a login system using JSP, I ran into several tutorials, and tried creating one by using java beans to keep track of the session.
    The bean stores the username by using setUserID(String userID), and also sets a certain variable to true if the user is logged in.
    To create different levels or types of users, and add more functionality to this login system, I believe I could add more properties to determine the level and other necessary information (with information taken from a database), and simply use a beanid.getProperty() to check for the information I need for example.
    I know that another way and the more common way to create a login system while securing other pages on the website, is to use session tracking and the session variable to set different values, etc... and keep track of the user.
    Now my question is, which one of these 2 solutions would you recommend? Which one do you believe to be more secure?
    Thanks.

    Arent both essentially the same? In the first, you set all properties in a single bean object and bind that object to the session. In the second, you bind each property individually to the session. So there is nothing to choose 'security' wise between the two options. Security, I believe, has nothing to do with how you track the user's session. Usage of SSL for example is a security technique.
    Having said that, if we confine your question to which is a better option for session management per se, I would favour the first (a single bean). I am not a great fan of a bloated session object though. You can always query necessary info from the db using this id rather than storing it in the session.
    Note you neednt set a variable to indicate that the user has logged in. The presence of the UserBean is sufficient to indicate the logged in status (assuming that you create such a bean only on successful login).
    Hope this is useful to you.

  • Which of these iMacs would be best for running After Effects?

    Hello, pretty simple question, which of these 2 iMac configurations would be best suited for using After Effects and other video editing software like Premiere or Final Cut Pro X?
    Option 1 - 21.5 inch
    3.1GHz Quad-core Intel Core i7, Turbo Boost up to 3.9GHz
    16GB 1600MHz DDR3 SDRAM - 2X8GB
    1TB Fusion Drive
    NVIDIA GeForce GT 750M 1GB GDDR5
    Option 2 - 27 inch
    3.4GHz Quad-core Intel Core i5, Turbo Boost up to 3.8GHz
    8GB 1600MHz DDR3 SDRAM - 2X4GB
    1TB Serial ATA Drive @ 7200 rpm
    NVIDIA GeForce GTX 775M 2GB GDDR5
    For some reason Apple don't offer more than 1GB of dedicated video ram in anything but the maxed out 27inch. Personally, I’m not fussed about the bigger screen and I would say that having the faster processor, double the ram and a fusion drive would be more beneficial than the extra gig in the video card but I’m not 100% sure, what do you guys think? Thanks.

    You need 16GB of ram for AE. Whether you get the 27 or 21 you still need that much ram. AE only uses the Ray Tracer for specific processes that are often not used. I would not worry so much about the GPU with this. Take the higher CPU and atleast 16GB of ram though 32GB is ideal.

    If you do a significant amount of video editing the larger display is nice but not absolutely necessary. I’d also recommend an SSD or Fusion drive rather than the stock mechanical drive which really is dog slow. If you choose an SSD 8GB will be plenty though 16GB is better if you go with the smaller model.

  • Which of these Macs would be a better machine?

    I am at the crossroads of getting a new Mac and I have two choices. Pretending everything else between the macs is equal besides what I am about to describe, which of these would be better?
    Choice 1. 15" Macbook Pro w/ 2.16 Core 2 Duo processor and 2GB of memory
    or
    Choice 2. 13" current issue 2 GHz Core 2 Duo Macbook w/ 4 GB of memory
    Why would the one you pick be better over the other?
    I'm not to savy with computer hardware so any help would be appreciated. Thanks!!!

    You are correct that many MBP owners have no problems and that the MBP is a better machine. I too had no problems for the first year and then within two months I have been plagued with unproductive days dealing with a computer that doesn't work. The issue is that for those of us that have these problems there doesn't seem to be a fix even with Applecare. There seems to be a trend with keyboard issues and Apple has not figured it out and provided a reasonable fix. If I spend the money and get a new keyboard I may be looking at the same problem if the keyboards are flawed. If you make your living with your computer sending it in to Apple for a week or two to get a problem fixed is not a great solution. I just think that the chance of getting a lemon in the MBP line should be factored into the decision. Maybe a new MBP has these problems worked out but to buy an older used MBP from the same vintage as mine would be unwise in my opinion.

  • Which one of these two drives would you recommend and why

    Hello,
    I am planning on adding an external HD to be used with Time Machine.
    I was looking at a WD My Book Studio LX 2 TB FireWire 800, then I saw another WD - 2 TB My Book Studio II.
    While the first look very nice and sleek with its aluminum case, and judging by WD website, offers more features, the second one seem to be faster (7200 rpm vs 5400 rpm) and it also offers 5 years of warranty compared with only 3.
    I am not a computer geek, therefore I am throwing the question here: which one should I buy and why? Do I really need that RAID technology?
    Thanks in advance for your answers.
    Regards,
    Loerincz

    IMHO, you want neither. I've heard enough bad things about WD drives on these forums that I wouldn't touch them with a ten-foot pole. Try [Other World Computing|http://www.macsales.com>. They've got quality stuff.
    As for RAID, you probably don't need that. RAID is a way to make multiple separate drives act like one larger drive, but that's major overkill for most home backup needs.

  • Test ACL to see which ACE is blocking traffic

    On the ASA and FWSM, is there a way to check which ACE would be blocking a particular traffic?  I'm looking for a command where I just tell it which ACL is use and feed it the source-ip/port and dest-ip/port.
    Thank you in advanced.
    Vince

    Hi,
    Well the ASA does have a tool that can easily tell you which ACL rule some traffic hits. Though I guess there is a very small change that you would have so old software that its not supported but I doubt it. This command isnt supported on FWSM however.
    On ASA you can use the "packet-tracer" command.
    Basically if you want to test traffic incoming from "inside" interface then you could do (IPs and ports are made up)
    packet-tracer input inside tcp 10.10.10.10 12345 8.8.8.8 80
    Traffic incoming from "outside" could be simulated with
    packet-tracer input outside tcp 1.1.1.1 12345
    I am not completely sure but on the FWSM (and also ASA side) side you might be able to look at the log message of the blocked connection and look at the very end of the log message that has a sequence of numbers. This might match some ACE in that interfaces ACL when you look at the ACL through with command "show access-list"
    For example I made a "deny" rule on my ASA like this
    access-list WAN-IN line 1 extended deny ip host 3.3.3.3 any
    I then generate traffic from source address 3.3.3.3 to one of my internal IP addresses and ASA generates this log message
    Deny tcp src WAN:3.3.3.3/12345 dst LAN:10.0.10.1/80 by access-group "WAN-IN" [0x6131ef0b, 0x0]
    I then check my ACLs with "show access-list | inc 6131ef0b" which essentially contains the number sequence I told about earlier. The output is the following and we have found the ACL rule that blocked the connection attempt
    ASA# show access-list | inc 6131ef0b
    access-list WAN-IN line 1 extended deny ip host 3.3.3.3 any (hitcnt=3) 0x6131ef0b
    Hope this helps

  • Which of these two macbooks (pro and air) will last the longest?

    I'm stumped between which of these two laptops to buy, I'll be using it daily at uni. Typical essay writing and internet browsing aswell as some garageband and probably logic use (nothing too heavy). Storage isnt an issue as I'll be buying an external hard drive without question anyway.
    Macbook Air 2013 11inches
    1.3 Ghz dual core i5
    8gb ram (paying extra to upgrade)
    128gb flash storage
    802.11ac wifi
    or Refurbished Macbook Pro with Retina Display 13inches
    2.5 Ghz dual core i5
    8gb ram
    128gb flash storage
    802.11n wifi
    About a £100 difference between the two computers
    I would prefer a laptop that is more portable and cheaper like the Air, however I'm willing to sacrifice this if the Macbook Pro is likely to last me longer. I want to get as many years as I can out of the computer. Any advice about which laptop to get? Or to take a different route?

    Honestly, there is no inherent reason why one would or should last any longer than the other.  If taken care of and not abused, either one should last many years.

  • Which of these two hard drives is best for SD-only video editing?

    Before I begin, I will start by saying that I realize the BEST hard drive is generally one's internal drive... but, ignoring that, my question is this:
    I have 2 external drives available, and can't afford to buy a new one yet. Which of them is best:
    1. 7200RPM drive, connected via FW400.
    2. 5400RPM drive, connected via FW800.
    I guess another way to phrase this question is, which is the more important factor, rotational speed, or connection method?
    Just wondered, as I do not have a 7200RPM drive that can use FW800. I want to use the best of these two until I can afford to get a 7200RPM FW800 drive.
    Thanks for any insight, and happy new year!

    William,
    A few people had chimed in great advise, but I like to add my own. Perhaps you will find this useful.
    The speed of the hard drive these days are hardly measured by the spindle numbers anymore. 7200 or even 5400 means really nothing other when it was made. That's the same as saying that my old 2.4Ghz Macbook is going to be slightly slower than a new 2.4Ghz Macbook or Macbook Pro. So just looking at the spindle rate is one thing. You need to look at drive generation, link speed, cache size, platter size and platter amount. For example, today's Seagate 7200 RPM drive is at 7200.12 and last year was 7200.11 (a disaster year for them as the drives would click themselves to death!)
    Let's start with link speed. The reason why internal drives are faster (at least with the all in one iMac, Mac Mini and Macbooks) is the fact that even at SATA I, it can operate up to 1.5Gbps, which is fast. FW800 is no match against SATA II at 3Gbps and SATA III at 6Gbps. Secondly, the throughput is well sustained with the help of DUAL PROC (Dual Processors) available on 2 Western Digital Blacks (one in SATA II and the other in SATA III flavours!). Digital Blacks come in 500, 640 and 1Tb. BUT, there is a Seagate most fastest drive in the 7200RPM category that is a 2Tb Barracuda XT which has a SATA III interface, though I doubt mechanical drives will achieve such high rates. These drives will simply saturate a FW800 interface port easily.
    When we are taking about throughputs, the 60-70MB/s the 5400RPM puts out is only good for the first 30 to 40% of its capacity, because they lie on the outer platter. As the head moves in, the throughput drops. This is a problem with a single drive. However, if you RAID 2 small drives together, then not only your throughput will more than doubled (saturate the FW800), it can be sustained for more than 40% of its stored capacity. Which is why RAID drives are used by professionals. It's easy to built a RAID drive. You can even buy one from the store. So if you want to buy a 1Tb drive, then you will be buying a 1Tb drive in 2 500Gb hard drive sizes RAIDed together.
    Another method I use if I only plan to have 1 drive is to "Short Stroke" it. Short stroking is very popular in the PC gaming world. Basically, what they do is run a program like HD Tune to determine what the best sweet spot that would give maximum throughput before it drops. Say a 500Gb gives the best speed for 140Gb, then they would go into BIOS and force format the drive to 140Gb. For
    yourself, you can partition 2 drives. First partition would be the smallest and that can be your "render" drive. The second partition would be for storage. It's quasi short stroking, but this will give you the most throughput if you need maximum speed for real time SD video editing.
    And Tom is right, always have a separate drive for rendering and never rely on your internal. However, if your internal happens to be 2.5" laptop drive, you can stick in a Seagate Momentus XT drive with its 4Gb SSD cache, it's enough to reduce disk access to the main drive so that's what I use for my Macbook. That's my read and OS drive and the Firewire 400 as my render drive and it's barely doable. FW800 would be nice!
    Good luck on your purchase!
