LAN Connection

**Anant Khaitan** · 07-03-2007

I have two system one loaded with Fedora Core 6 and other with Ubuntu 7.04, So I wanna setup a LAN connection between the two PCs for easy file sharing, internet sharing and others if any.. So if anyone can guide me through the steps/equipments required. Presently I just have a Ethernet wire(RTL-8139/8139C/8139C+), I don't want to go to hardware shop for Router or Hub or whateva if possible. Let me also inform you that I am a complete noob in this networking thing/LAN etc. so detailed instruction will be appreciated

Fine. If you don't want internet sharing and if you are concerned about communicating between the two systems, a single RJ45 cable is enuf. You can straight away connect.

But if you need Internet sharing,
either you need two NICs on one system (to which Internet cable is connected) and another system with one NIC. So that the system with two NICs can do the job of a router.

Or a router with minimum two ports to connect both the systems to it. So that both can be connected to Internet.

Ok communicating includes File sharing I hope.. so please elaborate the steps..I have heard of Samba and NFS but have no idea how to use them..
Thanks in advance..

Yes, File Sharing is very much possible.

Setup:

FC6 ------------------ Ubuntu
(10.0.0.1/24) (10.0.0.2/24)

Say, you want to share files from FC6, directory /home/dad.
1. vi /etc/exports
2. Enter this line: /home/dad 10.0.0.2(rw,sync,no_root_squash)
3. Save and close the file
4. Start nfs service: /etc/init.d/nfs start

Now goto Ubuntu:
Say, you want to mount the directory on /media/network folder.
1. mount 10.0.0.1:/home/dad /media/network
2. Done.

Hope this helps.

Tell me how do I assign/know the IP addresses of system.
Well ifconfig returns:
1> FC6

Code:

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0

ifconfig <interface_name> <ip_address> <netmask>

**Anant Khaitan** · 07-05-2007

This will assign the IP for my computer or guest computer..
I issued this:

Code:

sudo /sbin/ifconfig eth0 10.0.0.2 24

on FC6 box and

Code:

sudo ifconfig eth0 10.0.0.1 24

on Ubuntu

and did what u said in post no. #4 but it is returning

Code:

mount: special device 10.0.0.2/<folder> does not exist

Both Fedora 6 and Ubuntu use NetworkManager. I would say all you need to do is get your ethernet cable (make sure it is a crossover cable, as you are not using a hub!!).

Then just plug in and let NetworkManager do its thing. I have configured several point to point connections this way and it never fails. You can use samba to communicate, and ssh is great too. In fact if you are using Gnome open Nautilus, click on the icon to enter the address by hand and try this

Code:

ssh://username@192.168.0.1

Where you input your username and the IP address of the other PC. You will connect to file sharing over ssh. Encrypted!

Now you pointed me right.. I noticed that I was not having a crossover cable, anyways I can make my own ..I have my clipper, wire, pins and .....
