Thanks,

lol - that's what we are here for! , you are not causing inconvenience

To link the 3 computers up together i suggest you get a router (probably the easiest way i can think off). Seeing as routers are not normally operating system dependent any router should work. (hopefully)

Are these computers going to be connected using cables or wireless (im also assuming here you have all the required network cards? If not you can check here for compatible hardware - http://www.linuxquestions.org/hcl/)

Also, are you going to be sharing an internet connection between them?

well i'd be looking at a switch not a router, unless you're generically referring to an adsl modem with router and built in switch. i'd leave routing for another day really, and if you do want to look at routing, put a linux machine in there as the router itself.

yeah sorry, acid_kewpie is right, you'll probably want a switch . . . i was thinking of an adsl modem router.

what sort of internet connection do you want to share? ADSL/Cable or a dial-up connection? What hardware do you currently use to connect to the internet? (that is of course assuming you have a internet connection, currently, where you want to set up your network)

Hello acid_kewpie,

So do you mean that I need a switch beside the router to do this network? I have " 3Com ADSL Wireless 11g Firewall Router ", but I'm using it to connect this laptops to the Internet, and I don't think it will work to connect this laptops with each other. what do you think ?
thanks for your help...

so you already have a modem router? well you probably don't need to buy any more hardware . . . thats if the modem router has enough ports to connect with all the laptops?

Hello tjyorkshire,

Yes I have a "3Com ADSL Wireless 11g Firewall Router with 4 ports" but as I said I'm using it to connect this laptops to the internet as a gateway to Internet and not a network. and what I want to do is to make a home LAN. so is that require a switch and a router or the switch will be enough, I sorry since I'm still new in Linux and I love it

yeah that has 4 lan ports, which means it has a built in switch. no need for any other hardware at all.

so, I'm guessing you have had them all working on the internet through the router then?
I'm assuming you are using a dynamic IP address for the laptops?
Well, if so, once they are all hooked up - you should try to ping one laptop from another

For example
Code:
ping -c5 192.168.0.2
(change the ip address depending on the address of the computer you are trying to ping)
This is just to make sure they can communicate with eachother first, before we start to set up file sharing or other network services.
Just ask if you need a little more help on that

If you can't ssh from from laptop to another, there's only a few possible causes:

1. You mistyped the command (or you referred to a remote host by it's hostname, and the hostname is not defined in /etc/hosts).

2. The built-in firewall on the router is blocking the ssh traffic.

3. You may not have openssh-server (or sshd) installed.

4. A local firewall on each Linux install on each laptop may be preventing ssh traffic.
