  1. No DHCP, NAT: Each computer has the same IP, which is the external/broadcast one, though NAT is sitting there ready to handle DHCP when you turn it on. Presumably this should also be pointless? Should you even be able to use the Internet in this situation?

    no DHCP, no NAT: Each computer has the same IP and NAT is disabled because it's irrelevant. You can't use the Internet unless you turn off all computers except for 1, because of the fact that we're assuming the home ISP only gives you 1 IP, like my ISP does.

    I'm also reading this http://www.iplocatio...etmask.php and trying to understand the role of the netmask/subnetmask, but I'm not sure if I should push my luck by asking how it figures into all of this. Every one I've ever seen has always been 255.255.255.0 or maybe 255.255.255.255 somtimes. Apparently this somehow performs mathematical operations on some IP address to help route data and keep us from running out of IPv4 addresses? I feel like this kinda makes sense but I'm not quite there yet.

    No DHCP, NAT: Each machine would need it's IP Address assigned Statically.

    No DHCP, No NAT: basically whatever computer is connected and set up with your external IP would be the one online. (Pointless unless you have a block of IPs from your ISP)

    Here's another way to think about it

    NAT On = You get IPs like 192.168.x.x or 10.x.x.x (Depending on your IP Schema)

    NAT Off = You get real IPs that someone could type in their browser and connect to such as 74.125.225.32

    DHCP is simply a process for handing out IP addresses.

    Regarding Subnet masks the long and short is they determine how many IP addresses are in your block of IPs

    P.S. Many people cheat and use something like this

  2. So I did a little bit of research on this keyboard, and it seems that the unifying software is simply to add new devices to an existing receiver. Not an initial pair / re-pairing.

    On that matter, the ad on Logitech's site for this particular model says "No cords, software or hassles. Just plug the tiny Logitech Unifying wireless receiver into a USB port and enjoy."

    So here are my questions for you.

    1.) what is the device name that shows up in your device manager

    2.) when you go to the properties and resources for this device what is the hardware ID?

    3.) Desktop or Laptop? (more of a curiosity)

    4.) What version of Windows?

    5.) does it work to get into your PC's BIOS?

  3. From the sound of things, it seems as if it is in standard DVD format and thus would play in any set top DVD box.

    In which case when it is inserted into a windows machine that does not have autoplay disabled they will get an option of how to view/run the disc

    The same will occur on the Mac, it will say "Hey this is a DVD Movie, what do you want to do with it?"

    as long as they have ever watched a movie on their PC/Mac before they should be just fine, worst case scenario you can tell them to put it in their set top DVD player

  4. It's actually really simple.

    DHCP / Dynamic Host Control protocol literally just hands out IP Addresses. if you turn this off you can just set all of your machines to static IP addresses and they can get on the internet/network without an issue. Devices that are not assigned to static will not receive an IP and therefore not go anywhere.

    NAT / Network Address Translation is the network equivalent to that little splitter you would use back in the day to get cable on two TVs instead of one. It takes one public IP address and translates packet data so that when requests are sent and received it knows what computer to send it to.

    If you were to disable NAT you would have a gateway and would have to have multiple static IP addresses from your ISP.

    Case in point if you buy a block of IPs from AT&T on DSL, you need them to change their device so that it disables NAT, then if DHCP is on it will hand out one of the static IP addresses from the ISP in it's own little DHCP pool, and each of these would be what I like to call "real world routable" or you can turn DHCP off and manually assign from that "pool" of statics yourself. (most people do the latter)

    I know I that seems a bit convoluted, but I hope it helps you understand better.

  5. Now I do want to make sure then if I can do my math all on one line or do I have to do them separate lines. My example is this 23(food cost) * .07(tax all the time) = 1.61 + 23 = 24.61 * .15(selected tip) = 3.69 + 24.61 = 28.30 or is there a simpler way to do it.

    Actually your math would be more like this (tip should be calcuated outside of tax)

    For argument's sake (im not saying do this) but i'll use three variables

    tip = 23(food cost) * .15 (selected tip)

    tax = 23 (food cost) * .07 (tax)

    total = 23 (food cost) + tax + tip

    so your code would be

    tax = (food_cost) * .07

    if listbox.text = "10%" Then

    tip = (food_cost) * .10

    Elseif listbox.text = "15%" Then

    tip = (food_cost) *.15

    End If

    (Yes I did that in VB to mess with you :P) No freebie code here

    total = (food_cost) + tip + tax

    or

    total = ((food_cost) * tax) + tip

    the other alternative would be to in your if statement set the tip as it's multiplier value and do your math as

    total = ((food_cost) * tax) + (tip * (food_cost))

    etc etc

    I never was that great at explaining how to use case effectively ergo why I suggested if all else fails do an if/elseif

  6. Well depending on what you have covered in your class, I would add the percents as members of the collection to populate the list, and then either use a case/switch depending on the string value of the box.

    http://msdn.microsoft.com/en-us/library/06tc147t(v=vs.71).aspx

    or if you haven't covered that still use the string collection to populate your % values and just use an if / else if statement again based off the selected string value.

    http://msdn.microsoft.com/en-us/library/5011f09h(v=vs.80).aspx

    the question is when do you want the tip value calculated? when a tip % is selected? or when you press a total button? That will determine what object and event to trigger your math

    Best of luck!

  7. Ok So if I am understanding this correctly, you need to enter the total, have a list box for the tip %, and based off the tip % selected calculate the subtotal, tax amount, and grand total correct?

  8. Hi guys,

    I have come into a few Sprint 3G/4G USB Dongles (Sierra Wireless 250U) and was looking to sell them, but I don't know if anyone can do anything malicious with the "data" that is on them. If you open Sprint's software for it, you can get the user information (basically sprint email for that device), a "phone number" for that device, and a MSID/IMSI_S (I have no clue what this is).

    I have been trying to find a way to wipe the data out, and the closest I've come is finding if I type in ##DATA# I get prompted for a Master Lock Code that I'm told only Sprint can give out. (And they aren't talking to me because I'm not the original owner)

    two side questions that are bound to come up so I'll answer them now

    No these are not stolen

    Yes the ESN is clean on them (swappa esn check showed clean).

    Any Thoughts? Ideas? Suggestions? Hacks to generate a Master Unlock Code Maybe?

    Thanks again!

  9. Hey Guys,

    I am trying to help a small tech shop get set up and currently they cannot get Cable unless they sign a year contract with Time Warner, and otherwise can only get DSL. Crappy DSL at that. However they can get a number of lines and AT&T does not support Bonding of lines in any way shape or form. Not really looking for more download speed, just some load balancing. I can't seem to find a DD-WRT unit that will do it, m0n0wall and smoothwall don't support it.

    The other Caveat is that it needs to support PXE either directly or through DNSmasq much like DD-WRT using another machine for the PXE server.

    Thanks guys

    Here's hoping something exists!

  10. Just fixed it, a response from another friend who had seen this before said to do the following

    net stop wuauserv

    C:\Windows\SoftwareDistribution\DataStore\Logs>del *.log

    rename C:\Windows\SoftwareDistribution\ (look below)

    Datastore > .old

    Download > .old

    SelfUpdate > .old

    delete c:\windows\windowsupdate.log

    net start wuauserv

    and it is working again... I pray noone else has to try to figure this annoyance out, but good to have for reference

  11. Hello all, I have a new issue that is stumping many a person around the world currently.

    The unit in question is a Lenovo Y560 Laptop

    Running Windows 7 Home Premium

    The issue started with what I can only assume is a hard drive failure.

    Purchased a new hard drive and ran the recovery discs that were created from the original install from factory.

    had a thumb drive with some data from the old hard drive so after the install i inserted it and went to do updates and got the following message.

    "Windows Update cannot currently check for updates, because the service is not running. You may need to restart your computer."

    So after many Microsoft Fix Its, and some random results from lenovo's tech database I removed the Intel Storage Manager software and I still get the same issue.

    Thinking it was perhaps Viral, I ran the restore again after a quick 0s DBAN wipe

    Same old story sans the USB drive, ok so not viral....

    Maybe the recovery CD is borked?

    So I call in a favor from a friend to get a MSDN copy of a vanilla Win 7 install disc

    long story short same thing.

    ok so maybe ram is bad somehow?

    run memtestx86 overnight, come back in the morning No ram errors.

    so here i sit with the computer that works otherwise, just can't run windows update and can't install some other Microsoft products (like the latest .net framework or Service Pack 1)

    Anyone seen this before or have ANY clue how to fix this?

    other side note is that I have ensured that the service for windows update and all dependencies are all started/running

  12. ARGH stupid forum didn't post my reply so here's the short version..

    linux based router (dd-wrt or soekris or other custom box)

    script to run that changes the wireless passphrase from a wordlist

    script emails a specific e-mail address (one that the workers can get to)

    use cron to run the script every 12 hours or every day at 6pm or 1 hour after close of business

    idiot proofing: skip the e-mail thing and get a ticker board (you know those things with the LEDs that schools run messages across) with a serial connection or something and output the new password to that... TODAY'S PASSWORD IS: pineapplesareyummy

  13. Hey guys I have an Acer G185H LCD monitor, it was cheap and it serves my purposes. here's where my question comes in though.

    The manufacturer has a "maximum Resolution" of 1366x768

    My Video card will let me crank it to 1440x900 and it still looks great! BUT! It has a little box that moves around the screen that says "Input Not Supported" and it will not let me access the OSD Menu until I lower the resolution back down.

    so anyone know how to keep my nice higher resolution that matches my other monitors without the annoying box?

    **I'm broke otherwise id just go buy 3 same size/make/model monitors

  14. Just wondering if anyone had any knowledge/experience with this... But I was wondering if it was possible to port Mac Software over to Linux for running natively.

    I figure it would be more possible than porting a windows program over since Mac OS is vaguely BSD Based.

    Thanks in advance.

  15. this could be a fun first timers project. you should check out the scripting language autoit.

    if (window exists "instant messenger" with text("power on") then execute("net system power on")

    the syntax here is improper, this can be done with only a few lines of code with autoit

    you should install autoit and check out the win zip tutorial

    I'm sure you will have a lots of fun.

    This is rather interesting if the autoit language can read what is in the window of an instant message...

    You can send text messages to AIM users.... I found the following link that says which #s to text to and what the message format needs to be on your phone

    Text message to AIM

    However! This still leaves the issue of needing a PC to sit on at all times to receive the message. The only other thing I can think of is if you are in fact running DD-WRT and could create a script that would check your google voice account periodically for messages and runs the commands that are in the text.

  16. I was wondering if anyone had Hulu Plus before I took the dive. I hear tell tale that even though you are paying a subscription fee, there are advertisements. Is this true? Also how soon is content updated? Like does a show air and its available the next day?

    If anyone has any info on this let me know. I have netflix now but I'm running out of stuff to watch XD

    Thanks!

    *edit* Also does anyone know if the PC streaming requires Silverlight? ie:// Can you watch Hulu Plus on Linux without jumping through hoops?

  17. I just wanted to put a warning out there to anyone else who might be buying Konboot.

    I was hit with transaction fees because they charged it as a PIN based transaction (without giving my PIN #)

    as well as an International Transaction Fee. *which makes no sense since their HQ is in CA and I am in OH*

  18. I had some hope when I saw the whole Boxee<>Netflix connection and remembered that I had a boxee account oh so long ago.

    Sadly even the Netflix app for boxee requires silverlight.

    /sigh I was trying to avoid buying a windows license for my soon to be media center box.

  19. Hey Guys, I have been searching for about 3-4 days on this. and I can't seem to find any way to watch my netflix streaming on linux. I have found/tried Moonlight and changed my useragent in firefox but that doesn't work. I get one of three errors (Saying that I need to install Silverlight, That I need to enable ActiveX, or that my OS is not supported).

    Everything I have seen on the net says to use virtualbox with Windows XP, but in my opinion that defeats the purpose of using linux in the first place.

    anyone else have any experience with trying to get this up and running?

    p.s. I have been fooling around with wine and still no luck.
