Ubuntu Networking :: Connecting Two Computers Without Ethernet Or Wi-fi?
Jan 11, 2011
I have two computers, a laptop and a workstation, both running linux (Ubuntu and Fedora).For some reasons, it's handier for me to work from the laptop, accessing the workstation only from remote.At present, I have to connect to the workstation using a very complicated system that implies VPN + ssh passing through the internet. It works, but it would be far easier and faster if I could set up a direct connection between the two computers. Unfortunately, I can't use the ethernet ports or wi-fi (it's a long story why, but I really can't).I own a usb data transfer cable, but I don't know how to use it.

When I try to use Nautilus to connect to another computer on my network, and I attempt to connect using the name of the Windows XP computer I am connecting to, I get the following error; Could not display "smb://computername/". Error: Failed to retrieve share list from server Please select another viewer and try again. However when I attempt to connect using the IP address on the network, it connects instantly. smb://192.168.1.101/ Why doesn't it connect using the computer's name? What am I doing wrong?

My computer needs the boot option "noapic". Unfortunately the Ethernet doesn't work. It does work when I use the boot options "noapic acpi=off" but the printer that is connected via a parallel port does not work. Also I have to push the power button the system is shutting down with this option.

I've been doing some reading and I cannot work out why I'm having this problem. My 32-bit Ubuntu Server running 10.10 has a Realtek RTL8111 ethernet card which supports up to 1000mbps. However, when I run sudo ethtool eth0 I get:
Code:
Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
[Code]....
After running sudo ethtool -s 1000 to try and change speed to 1000mbps, the output is still the same as before. Why is this :S?

just recently I made the move back to Ubuntu from Windows. Upon re-installing I noticed a problem with me connecting to the internet. Previously on Windows I had updated my Ethernet Adapter driver, upon installing I would have to disable and re-enable the device to let my computer have access to the internet. My problem here is how would I go about fixing this on Ubuntu so I can have internet access on Ubuntu

The Wired Internet adapter isn't working with Ubuntu 10.10, and without this working, I can't get my updates for the Broadcom WLAN adapter. I have a Realtek RTL8101E/8102E PCI-Expredd Fast Ethernet controller. I have looked for solutions, but haven't found any relating to my problem.
To be specific: Ubuntu 10.10 is recognizing the Ethernet adapter as eth0. When I try to manually connect after inserting an Ethernet cable connected to the Internet, it tries for a couple of minutes before telling me the adapter's been disconnected. The connector lights remain the same on the port as they always were.

I tried to setup sharing to connect Ethernet and wireless. I want Ethernet connected to desktop A, and wireless connected to another laptop(B), with my laptop acting as an AP. I set the network settings in Firestarter: Internet for wireless, local network for Ethernet. I want to share Internet from laptop B over the network. Internet won't work from my laptop since it seems to use the wrong interface.(Since the desktop is sharing Internet, although not on Internet usually when connected via Ethernet. And of course DNS/Gateway IPs aren't set for wlan0 since it's acting as an AP.) SMB wouldn't work for desktop A and laptop B: laptop B could detect desktop, but reports error "Path not found".

I have configured Ubuntu 10.04 to work on a Windows XP network that has 2 other XP desktops (wired to same router). Ubuntu sees the icons for each computer in the "network" tab of "places" and can access the shared files 1 of those desktops, no problem, but trying to access the other one gets the error "Unable to mount location-failed to retrieve share list from server" I have checked the XP computers and can't find what may be different about them.

I'm trying to connect 2 Ubuntu computers with a crossover cable (ethernet). I found the following thread:
[URL]
Its says to go to:
1. In System > Preferences > Network Connections
and under IPv4 tab, change Method to Link-Local Only.
The problem for me is I'm using Xubuntu 9.04 (on 1 of them) and I don't have "Network Connections". Is there a way to get this utility in Xubuntu 9.04 so I can set the method to 'Link local only' ?

I have 3 computers connected via an ethernet cable to the same ADSL modem. Each has its own internet address and what appears to be a local address (10.1.1.1, 10.1.1.2 etc).
I would like to enable file sharing between the three but I don't want one of them to be a gateway for the others and I don't want any information that the 3 computers share to go out on the net.
So far, the slack book and man pages imply that years of research are ahead of me and none mentions a "gateway free" configuration.

Ever need to provide access to multiple PC's and did not have a router only a hub. Maybe this isn't original thinking, but then again maybe you didn't think of doing it this way (which i am sure there are many ways to do it) So I have 2 Ubuntu Servers, 1 Windows Box and a Hub - All 3 with internet access off of single ip and single Ethernet port.
While searching for a backup method today I came across Clonezilla. I was wondering if this was the right thing for me and since I needed to backup my roommates PC for a reformat and install of Windows I decided I would give it a try, but only if it would work. I didn't want the hassle of going into the main part of the house and finding out what cord was what as there is a cable modem connected into a switch (4 static IP's with internet) and one port of the switch hooked to a router) Anyways, didn't work he was on the router I was on the switch)
But this got me thinking. When I setup my server to do this, during one of the setup scripts it said it was setting up Internet access for client machines and that it was assigning them IP addresses threw a DHCP server that it had installed.
So, I dug up the hub connected the internet cable to hub up link and Server 1 on port 1 Server 2 on port 2 and Windows on port 3 The main server gets the internet provided IP address and routes it to the hub via a virtual interface. Server 2 is configured for DHCP and the windows box, It was set to get info automatically but it didn't fill the DNS info so I had to manually do that (just a heads up) I decided to use OpenDNS Servers (208.67.222.222 & 208.67.220.220) but im sure putting in the gateway IP address would have worked too.
So, by now if you need this I am sure you are excited and want to get to it. Like i said there are probably other ways of doing it, ways that don't involve you installing clonezilla and DRBL, maybe even just DRBL is needed, maybe one of them installed whats needed as a dependency- all I know is it works, if you know - elaborate so people know, but hey- this way not only do you have internet access on all PC's you can deploy custom images to them as well.

i have ubuntu 10.10 64b and for some reason last night the wired network autoeth01 suddenly will not connect to my router. it is a dual boot machine so i booted into windows and it is working fine in that OS.
I then had a look at the status on my laptop running ubuntu 10.10 32b and that was showing the same message "wired network autoeth01 disconnected" i cannot for the life of me figure this out. just before it was disconnected i had been copying 7gigs worth of data using samba from the 32b machine to the 64 bit machine.
i have tried deleting the wired entry and recreating it.
tried different cables
even changed the router
works with all windows machines connected to network
here is what comes up in lfconfig:
jason@ubuntu1:~$ lfconfig
No command 'lfconfig' found, did you mean:
Command 'fconfig' from package 'redboot-tools' (main)
Command 'ifconfig' from package 'net-tools' (main)
Command 'ldconfig' from package 'libc-bin' (main)

I've been trying for a few hours to connect to the internet on my debian jessie system. I used the netinstall without installing a DE so I boot into the command line for the mean time.
I have had no luck connecting to the internet after trying to configure the network. I have followed the debian tutorial from the wiki and tried some youtube video tutorials. I just have an ethernet cable connected to my home network. I have tried both dhcp and a manual static setup using /etc/network/interfaces and checked the /etc/resolv.conf file. Ping doesn't work and i cant update or install anything on the system...

I just did a fresh install of Squeeze with a KDE desktop on my computer. I use this computer to run an instrument in my lab. The instrument is connected to my computer through an ethernet card. Since my reinstall I cannot figure out how to get my computer and instrument communicating again. I'm guessing that I need to somehow tell my computer to connect to the device, but I don't know how. Here is my interface configuration:
[Code].....
I think my instrument is connected to eth2, which does not show any inet addr or Bcast ip, so I'm guessing that is a problem. How do I fix this?

I just installed Fedora Core on my Dell Inpsiron B130 laptop and I am having trouble connecting to the internet both wirelessly and with an ethernet cord into the router. When trying to configure my network, I dont recognize any of the ethernet adapters in the drop down list. I have been told that my wireless card is Linux compatible (dell y8029 dell wireless 1370 802.11/a/b/g mini pci). My ethernet card is a B130 Broadcom Ethernet Driver which isnt in the drop down menu either.
I read that I need to download an ndiswrapper but I dont know where to find this download AND even if I could download it to a zipdribe, I have trouble opening a USB flash in Linux becuase its not a "valid block device". This is after the command "mount /dev/sda1 /mnt/usbflash"

I successfully installed Ubuntu 10.04 on 2 laptops (both are identical in terms of hardware). In addition, I connected both of them (using RJ45 cables) to a switch (just a switch; I don't have a router). Can anybody guide me what should I do / what settings should I specify in each laptop in order to be able to SSH from one laptop to another?

We have 5 computers networked with 9.04 installed. On some days, when you click on Place -> Network, then all the computers will show. On other days, like today, it does not show. However, one can ping them and I have been able to print to one computer which has the printer attached. SAMBA is installed on the computers for file and printer sharing.

I have a small home network. Computers A and B are both running Kubuntu Lucid. Computer A has an external USB hard drive attached, partitioned ext3 and mounted to a folder in computer A's home folder. Computer C is running Vista. I installed Samba, and computer C can access all the files on both computers A and B. But using Samba, computers A and B can't see each other OR computer C. That's not really important to me, but they can't
So I installed NFS and got computers A and B talking that way. I like NFS better. It's faster than Samba. BUT, computer B can't access computer A's USB drive, and I need it to do that. When I'm using computer B and I click on the folder the drive is mounted to, the file manager just shows the folder as empty.

I'm using Ubuntu on my laptop but I'm having a small problem. The network is working fine except for the fact that I can't reach anything on my LAN (can't even ping the router), but everything on the outside works just fine. I can even visit my webserver if I type my public IP.
Where should I begin looking for faults?
Here, enjoy some data. I'm using my wlan0 interface, not sure whether eth0 works or not.

I want to be able to access my desktop from work so I first set up a DNS. I can ssh into my own computer and using the ip address but when I try to ssh using my DNS (this is from my home wireless which is Linksys E2000), I get the following error:
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug1: Connecting to ****.com [74.79.145.28] port 50000
debug1: Connection established.
debug1: identity file /home/andy/.ssh/id_rsa type -1
[Code].....
I set up the settings on the Linksys to accept DDNS but I am thinking there might be something else I overlooked? I do not understand completely what is happening to debug this. It seems like it initially accepts the connection and then something strange occurs.

Just to gain access to one of my computer across the house I use VNC a lot but the computer changes its IP address every so often that I refuse to just get up and check it. Without giving that computer a static IP address, is there a way to hunt down the computer's IP?

I have two desktop computers on the same home network and I am unable to share files between the two. Both have access to the network. One is able to file and printer share using SAMBA and a windows 7 laptop. The other machine is unable to either do file sharing via Samba or SSL file sharing between the two Ubuntu machines.

I'm having some trouble addressing computers by name. I've just upgraded most my my box's to Lucid, and it was all working fine, but suddenly stopped - not quite sure why, or what I did, but I need it to come back! At first I thought it was my old router dying (which it was) but a new router hasn't helped.
I've now moved DHCP from the router to my server, and that's working fine, giving out static IPs from MAC addresses, and so forth, but I still can't address anything by name. My server is on 192.168.100.1 and called myth-server, if I
