Ubuntu – Connecting 2 ubuntu machines as a LAN

lannetworking

Hi i am trying to connect 2 ubuntu computers as a LAN.

In my current setup I have:

One machine running ubuntu 11.10 with Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller

While the other machine is running Ubuntu 12.04 with an Atheros Communications Inc AR8152 v1.1 Fast Ethernet

The two machines are connected via a switch (Edimax ES-3205P).

Unfortunately I still cannot connect the two machines together. Can somebody please show me what to do and how to go about solving this issue?

Thank you

All I had to do was set up both ip's maually, subnet mask to 255.255.255.0 and left blank both gateway and DNS.

Just set the IPs manually using the 'network connection' GUI to, say, 192.168.1.1 on ubuntu 11.04 machine and 192.168.1.2 on ubuntu 12.04 machine. Set the netmask to 255.255.255.0 on both of them. Leave the dns and gateway fields blank (I am assuming you only want each other to talk with no internet). This will work. If you wish to connect just these 2 machines, then there is no need of a switch - directly connect each other with the ethernet cable.
(I assume you know how to create a new connection in ubuntu and set the ip manually.)

Ubuntu – RTL8101E/RTL8102E not working with ubuntu 14.04. HP G61

I have a Dell Inspiron 3521 Laptop. After update from Ubuntu 12.04 LTS to Ubuntu 14.04, I had the same problem with my eth0 network card (an RTL8101E/RTL8102E). Using lspic (list PCI devices) to show the devices in the machine, with:

lspci -nn

06:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller [10ec:8136] (rev 05)

(It was not present at ifconfig command)

I download the driver from Realtek to my Desktop folder from: driver's page

Then I untar the file and open the path to a terminal and install it with:

$ cd Desktop   
$ tar xvvf r8101-1.025.00.tar.bz2    
$ cd r8101-1.025.00/src     
$ make clean modules    
$ sudo make install   
$ sudo depmod -a
$ sudo modprobe r8101
$ lsmod |grep r8101
r8101                 153264  0 
$ /sbin/ifconfig -a    
eth0      Link encap:Ethernet  HWaddr 74:86:7a:5d:c6:01  
          inet addr:192.168.1.4  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::7686:7aff:fe5d:c601/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          TX packets:258622 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:347809708 (347.8 MB)  TX bytes:143626976 (143.6 MB)
          Interrupt:47 Base address:0x4000

For me it worked ....

Edited to remove superfluous commands that would cause no action in example, and to add sudo usage where appropriate.
