Some very "newbie" networking questions -- trying to get started

Hello all. Since this forum is so friendly for issues related to Arch, I thought I'd post my semi-arch related question.
I'm trying to create a network for my house, consisting of about 3 computers. I have a book reference, TCP/IP Network Administration from O'reilly, but I think I need a bit of a "kick-start" in order to get to a level in which I can comfortably understand the book (if that makes sense).
I've got internet access working by connecting to a router and having everything configured by DHCP (ie, in rc.conf, eth0="dhcp"). What's bothering me (and I don't even know if it should) is that the other computers on the physical network are not visible to me.
IE, when I try to connect to them with their host name, it doesn't recognise them. My understanding of that is that either I need to manually set the hostnames of the other computers on the network in /etc/hosts, or use something like a DNS server on one of the computers in the network in order to recognize the others.
My other doubt is that I think I've got a dynamic IP address (though it might be static, I'm not quite sure). Does that change things?
I don't expect you guys to completely run through me setting up the network (that's what the book is for!) but some basic advice on either my misconceptions (I'm sure I have plenty) or related in general to my situation would be awsome and highly appreciated. I'd also be happy to provide any additional info that would be helpful.
Thanks in advance.

My set up is simple.
I have a Linux router running on an old Pentium machine. It has two cards, one configured for the private network (with an address like 192.168.1.1) and the second card set up to take addresses from DHCP ( since that's how Rogers sends you the public address).
In that machine I run my firewall, SmoothWall (smoothwall.org) and have enabled NAT so the machines in the inside network can go to the Internet.
I have Samba set up in another machine to share files (that's an Arch system) with static IP, my daughter's machine (another Arch system), my system (obviously another Arch with static IP) and my wife's machine with Windows XP system (static IP too).
So, the key concept here  are:
1. Use static IPs for the private network
2. Use DHCP for Rogers
3. Use NAT in your router so all the machines can go to the Internet but no one from the Internet can get to them.
Hope this helps.

p.s. feel free to contact me off the list if you need further details/help.
Aha! So, for example, the network 192.168.0.0 where mask is 255.255.255.0 is a private network set up by my router, right?
So the addresses in 192.168.0.0 never change, but the public IP address of the hosts do change?
Does that mean that if, for example, I have a host called 192.168.0.32 that its address never changes? Can I simply add that to all the other hosts' /etc/hosts file and it won't change?
All I was ever concerned about was allowing hosts in the network to contact each other via hostname. If that never changes then I'm all set.
BTW, thanks for your continuing help!

    If the apps are compatible with the device (e.g. you have at least the minimum iOS version, and it's not, for example, and iPhone-only app that you want to install on an iPad), then you should either be able to re-download it directly on the device via the Purchased tab in the App Store app, or you can sync it via your computer's iTunes.
    If you are having problems getting the app on the device, then what is the app (and is it compatible with that device) and what iOS version is on it (Settings > General > About > Version ; an app's minimum iOS version should be shown on its description page in the store).

  • Very simple network question

    Forgive my stupidity asking this question...
    I have an iBook G4 and two Windows PCs (one W2K, one XP) all happily sharing a wi-fi network using Airport Express.
    I am about to dash out to the shops to buy a USB printer so that we can all print wirelessly, using iFelix's fab website for guidance. My incredibly dumb question is this: do I need to establish any kind of network before embarking on the printer-sharing project, or, by the very fact that we are all sharing a wi-fi network, are we already three "networked" computers??
    I don't want to share any files between the computers, just a printer. Is there anything I need to do beforehand to create a network, or are we already one??
    iBook G4   Mac OS X (10.3.9)   Window XP, Windows 2000, AirPort Express

    Sanhodo: there are reports of problems with windows sharing a printer to a wireless iBook. You should read iFelix guide to wireless printing (run a google search), it will shed some light on the subject.
    JFYI, the setup of Claudine is completely different from yours, since she will connect the printer to THE ROUTER, not to a computer --which is your case-- and therefore she will avoid the problems of windows printer sharing...

  • Very newbie Xcode question

    Hey guys, I've VERY new to Mac programming and am having a problem with Xcode. I'm trying to run the basic Hello World app, and it compiles okay, but nothing happens then? As in I don't actually see any results. So far, I've created a new project, then edited main.m in Other Sources to this:
    int main (int argc, const char *argv[])
    printf ("Programming is fun.\n");
    return 0;
    I click Build and Go and it seems to compile okay but nothing else happens. How do I fix this? Thanks for reading!

    Yup I ran into that the first few times I looked at a podcast on Cocoa and got that answer Keep coding !!

    I haven't used Garageband before and can't seem to get past square one! I bought a First Act usb guitar cord to record guitar, when I plugged it in Garageband seemed to recognize it, and it looks like I'm getting a signal and can see the waves when I record, but I can't hear anything. Is there something special I have to do to actually hear what I'm playing through my iMac?

    I have a domain name and am going to sign up with a web

    Contribute can only be used to edit a site that's already
    built. It can
    allow you to create new pages at an existing site, but it's
    not possible to
    create pages from scratch and build a new site. If you're
    looking for
    something easy you might look at NetObjects Fusion for

  • Some more newbie java questions

    Ok, so I have to write a method that takes a positive integer parameter and returns the number that results from adding up the digits of the parameter. Now, I have NO idea how to approach this, can anyone help me please?
    As well, how can I find out how long an array is without actually being told? Because for another assignment, I need to write a method that compare's one array to another; however, it must be dynamic in that the method must be able to compare any array that is greater then one. So, I know that you must use a loop to compare the individual element's of the array's; however, how will I know when to stop the loop? In other words, what should be the condition to stop the method?

  • Trying to Get Started With Windows 8.1

    I'm not a troll, I'm just a crotchety, oldster trying to figure out how to get Windows 8.1 to fit my workflow.  I've been using Windows 7 for the last bunch of years, so I'm a bit late to the Windows 8 party, but I'm building a new PC and figured I'd
    move to 8.1 instead of continuing with 7...
    I liked the XP interface - extremely easy to find the application I wanted because things were hierarchical. Windows 7 was more bothersome, but I got used to it.  So far, after 3 days, I'm still struggling with Windows 8.1, so I figure I'll get some
    guidance here...
    I did a rummage, but didn't find much on how I should change my workflow to make it easier in 8.1.  In Windows 7 I had a desktop with icons for less frequently used applications, a taskbar with frequently used applications pinned, and a start menu (3rd
    party) with EVERYTHING organized hierarchically so it was easy to find what I need. I'm trying to use 8.1 without adding a bunch of 3rd party stuff to make it look more like older interfaces that were organized differently.
    In Windows 8, I appear to have the equivalent of THREE desktops, all different, none with any hierarchical organization.  
    I'm not seeing the advantage of the Start screen...  Are the boxes, of whatever size, just the equivalent of icons or do they do something better?  And I only appear to be able to organize horizontally, which means I'm limited to six named groups.
    On the Apps screen, I already have a large number of my apps, despite deleting a bunch of the "modern" things.  They exceed the width of the 24" monitor I'm using for setup.  There doesn't seem to be any hierarchy there, either. 
    So, for example, for Office I have at least 12 icons/apps/whatevers.  Including the ones I CARE about, like Word, Excel, Powerpoint, and Outlook that I use regularly.  AND a bunch of OTHER stuff I VERY rarely use like Clip Organizer, and Groove,
    and Uploader, and so on.  But, I can't take them off the screen if I ever want to get at them, right?  'Cause there's no start menu any more...
    I also have a lot of stuff for handling e-books - Calibre, a Kindle Reader, OverDrive, Adobe Digital Additionsl, a Nook Reader, a couple 3M cloud things, and so on.  On the Apps page they're all OVER the place instead of being grouped together (which at
    least the Office stuff is).  And there doesn't appear to be a way to have them be together and hierarchical so I can quickly find Calibre or ADE quickly, and only have to see the Kindle reader or Nook reader when I want them...  So how do folks organize
    their screens so they don't have to wade through hundreds of things you only need once a year to get to the ones you use a couple times a month or once a week?
    I also have a bunch of stuff that's just a single application, like Syncback, but instead of just being "Syncback", there' ANOTHER line that tells me who the creator is - I don't care that 2BrightSparks made it, I just want to be able to find it when
    I need it - once in a while.
    The desktop is as it's always been, but I don't want 2 or 300  icons on there for a bunch of stuff I rarely use.  The constantly used stuff will be pinned to the taskbar, and the less frequently can be icons, but where do I do to organize all the
    other stuff?
    So, in my ignorance - is there a way to have 8.1 support MY workflow, or if not, how do other people organize things to make it as easy as possible to find what you need without having to wade through a ton of stuff you don't?  And have it all fit on the
    screen. 
    I found the Name Group thing for the Start screen, but I can only group applications aross the screen?  Which limits me to 6 groups.  How do I configure that screen so I can have multiple groups in a column?
    And the Apps screen.  How do I organize things hierarchically so I can have the Office stuff I care about visible, with the rest not clogging up space but available for drilling down?
    I currently have the system boot to the desktop, which is most like Windows 7, but without a start menu to group things, I'd need a lot of icons for the applications I use, and a lot MORE for the stuff I rarely use.  Cumbersome.
    How are other people organizing in 8.1?

    I have a Dell U3014 as well as a couple of older Dells turned up sideways as "ears".
    Other than supplying the desktop "theme" (if you can call a complete lack of style along with a fair bit of inconsistency a "theme"), the OS really shouldn't be causing you to have a washed-out desktop experience.  That's more a
    matter of your display driver not really doing its job.  What video card do you have?
    FYI, one of the reasons I like Aero Glass for Win 8.1 (a 3rd party package) is that it allows me to make the desktop more pleasant to use and helps set the client areas (i.e., where work gets done) apart from the window chrome.
    From what I can see, the color-management logic in Windows 8.1 is essentially unchanged from what it was in Windows 7.  That there has been NO progress in this area is really a disappointment.  It's an area where Microsoft has again just stopped
    trying to make improvements.
    If it's at all interesting to you, here's a screen grab of a REALLY cluttered up desktop.  I don't normally work this way; this was an exercise to see how much I could get running.  I finally gave up starting more stuff as I grew tired
    and it just kept working fine...

  • Trying to get started with iPad

    I received an iPad for Christmas. However, I have an iMac 17" flat screen PowerPC G4 running Mac OSX 10.4.11 with iTune 8. (Yes I know I am a little behind the curve but it all as worked for me until now.) On the iPad box it says I need OS 10.5.8 and at least iTunes 9.1. I am covered for the iTunes as I have a copy of iTune 9. My problem is finding OS 10.5. I did a little research yesterday and found 10.5.4 for $200 which I think is quite high since I want to recall the original release for 10.5 was only $129, and the upgrades are usually free from Apple. Also there is no guarantee that I'll get a PowerPC version. I ran into that with some other older Apple software I ordered from a third party. Any suggestions on were to turn to get a copy of 10.5 for a PowerPC G4?
    Thanks for your help.
    Retiredmac

    Well, I was curious about 10.5 and googled it. Seems the "going" price for a new box is $199, but I did find a link to Amazon where it was on sale for $162. I would recommend doing an extensive search for Mac OS X 10.5 and see what prices you might find. But it seems that, unless you are buying used, the price will be much higher than $129.
