Ubuntu Networking :: Eth1 Wirelessif Toshiba Satillite A25-S207 Won't Connect
Jun 7, 2010
I've been trying to get my old laptop (Toshiba Satillite A25-S207) to come up on my LAN and connect through a LINKSYS ROUTER WRT 160N V3. My router has been operational for at leased 2 months with no problems. The status logs reveal all other devices are connected. The Toshiba eth1 does not show in the router log during any attempts to connect. Also, pinging from the Toshiba laptop to the router's IP:192.168.1.1 times out. Using the ping routine from the routers internal diagnostics menu times out for the laptop.I have gone over the FAQ's and post concerning troubleshooting and setup of the wireless network interface. I have dumped wireless information as "super-user" using the suggested routines (i.e. lshw, lspci and the system test from the ADMINISTRATION MENU from the desktop task bar,etc...)
These have revealed I do have some sort of configuration problem or conflict. I'm just not savvee enough to work this out. The wireless interface apparently is using the orinoco driver and the wired interface eth0 is using 8139too driver.I forgot to add, that the router is secured by WEP key. Also, I disabled the WEP which did not change the connection problem. I used the manual setup from the taskbar and made incremental changes with the encryption setting with no results. I didn't expect to affect the status. Because, I noticed that the WEP key didn't seem to configure in the settings the interface as reflected by the attached text.

My wireless (Toshiba laptop, 10.04 64 bit) is just hanging when trying to connect. It was working fine but now nothing. My Wireless antennae is on and my other laptop can connect with no problems. I have restarted the router and the laptop twice.

I have 2 LAN ports. one from the motherboard (on board) and the other from a lan card i bought a few days back. one is use for browsing the net, the other for a media player.
problem is i cant connect to both the eth0 and eth1 at the same time. i have to disconnect one of them to connect to the other. and this really gets irritating as it doesnt always work as flawlessly as it should. what am i doing wrong?
Output of "ifconfig":

getting the wireless chipset (Realtek 8176) to work, but finally got the WLAN to show up. Now, it seems as though it will recognize my WLAN and SSID, ask for my WPA password, but never connect. I connect fine over wired ethernet. It will not connect wirelessly to an unsecured network either. I previously had Jolicloud installed on my netbook, and my wireless worked out of the box with no setup, but I really didn't like the lack of application support with Jolicloud. I ended up in dependency hell just trying to update Banshee for use with my iPod.

I cant seem to understand what happens to my wifi networking, i just installed ubuntu 10.10 today (completely erasing windows) on my toshiba satellite m645. Seems like my wireless card (the specs say its intel 802.11a/g/n wireless LAN) will only randomly detect the available networks or will connect only for a few seconds just after i just turned it on, then it will disconnect.

Toshiba Satellite 1905-S303
Ubuntu 11.04
2.6.38-8-generic i686 Kernel
The Network card sees the Wireless network, but will not connect to the router. I have tried with and without security, and neither setting makes any difference. Using the Wired Network adapter does work when set to a STATIC IP.

I try to generate a server client code. What i try to do is sending video streams from eth0 and eth1 to the other server programs' eth0 and eth1. In order to do that, i decided to use SO_BINDTODEVICE. But the code is not working. Am i misunderstood the usage of SO_BINDTODEVICE.
1-Defining two ports
2-Defining two sockets
3-Assigning host ips on them

I have a hardware device with two ethernet ports, eth0 and eth1 running Centos 5. Basically my goal is to forward packets from eth0->eth1 and eth1->eth0 as well as get a copy of these packets for analysis. If I set IP routing to do the forwarding then I won't get a copy of the packets for analysis.

Off and on for some time now I've been using a Toshiba x205-s9359 laptop with (11.4/KDE4.6) during the day as a general purpose laptop using the onboard LCD and in the evenings to run XBMC to play movies on a TV using an HDMI cable (no cable TV on our little island & Satellite TV is poor in the rainy season).
The video card is an NVidia GeForce 8700M GT with NVidia's proprietary driver v. 275.09.07 (installed the "hard way").
Audio info:
Code:
~> aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC268 Analog [ALC268 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
[Code]....
Now the Audio/Video both go to the TV via HDMI if it's connected prior to boot, if not the laptop works normally.
If you try this with XBMC don't forget to go to set the XBMC settings to "HDMI" as needed.

I am running Ubuntu10.04 as a Virtual Machine in virtualbox.I changed my Networking settings from NAT to Bridged Adapter and manually assigned IP addressing information for eth0 in /etc/network/interfaces. For some reason doing /etc/init.d/networking restart didn't bring up the network interface. So i replaced the new /etc/network/interfaces file with the original and rebooted. Now I have eth1 in place of eth0. Under System>Preferences>Network Connections I have Auto Ethernet and eth0. However running ifconfig shows lo and eth1.

I'm no expert on DHCP. My problem is that i have a CentOS 5.5 server on which i want to install a DHCP server. I have two NICs where eth0 has access to the internet and where eth1 should act as an DHCP server.
I have installed dhcpd and this is how my dhcpd.conf file looks like.
Code:
ifconfig looks like this
Code:
When i start dhcpd on eth1 i get no error messages but when i connect any devices to eth1 they don't get any IP. I cant find anything in any logs about devices trying to get an IP address. I dont have any firewall rules in iptables.

My wireless suddenly no longer works either in Ubuntu 10.10 or Windows 7. Upon some investigation, I have found that my eth1 is no longer showing up as it used to.
What can I do to get my wireless back?
Right below is some current specs, while below that is an older set of specs from a while ago.
Code:
sef@sef:~$ lspci

I'm having a strange problem. I'm using Ubuntu server 10.04 LTS and I want to setup a system with 2 network interfaces: eth0 and eth1. However eth1 does not come up at boot I have a screenshot of my /etc/network/interfaces file I don't see what is wrong. eth0 gets it's adress from DHCP eth1 gets a static adress. When i try to restart networking it quits with this message "don't seem to be have all the variables for eth1 inet" Can anyone point out what I'm doing wrong? if i do 'sudo ifconfig eth1 192.168.3.1 netmask 255.255.255.0 up' eth1 comes up

I have static eth1 defined. When I boot or restart, the networking will not start automatically - i must do it from terminal by ifup eth1.
Where can I put this command to have it autostart?

I am working on USB Connectivity between android 2.1 Host and Windows Mobiles 6.1 device...When I connect the windows mobile device to android host through USB (in RNDIS Mode), It is appearing as 'eth1' interface instead of 'usb0' interface. Why 'eth1' instead of 'usb0' ? Does behaviour of 'eth1' is same as 'usb0'?

I have an older laptop, a Toshiba Satellite Pro 6100 that has a switchable internal wireless connection. It will not connect to my router. I am using the 10,04 netbook remix. When I use lshw in terminal this is what I get:
*-network
description: Wireless interface
physical id: 1
logical name: eth1
[Code].....
Should it not be identified as wlan0? I know a whole lot about Ubuntu linux because I don't. I did a clean install over XP and am using this laptop as a learning tool for linux in hopes to divorce windows completely.

I have a bit of a "unique" situation here. I have myself plugged into two networks - since we run two networks here at work (long story, we merged and never combined them due to two different companies) and want to block ALL internet access off eth1, and only have it off eth0. I only want traffic from 192.168.67.1-192.168.67.255 allowed on eth1, but everything allowed on eth0. Or is there a way for the internet/applications to be on eth0 instead of eth1? Would I use iptables or something?

I've noticed that when Linux boots on different machines or with different versions, the network card is assigned to eth0 or to eth1, when there is only one network card. What is the difference and is there any way to tell which one it will be for any machine or version?

I often run "gulp", a networking utility, to capture data from an instrument on "eth1". By default gulp must be run as root to have access to the ethernet port, and when I'm the only one running it, that's fine. But I need to let several other users to capture data and don't want to give them all sudo permissions for both gulp, and more importantly, 'chmod'. Is there anyway to change the permissions of eth1 to allow all users to open it and avoid sudo entirely? This is on a Red Hat/Fedora machine.

I installed Slackware 13.37 console only.
I have two ethernet cards.
I want to change eth1 to eth0 and eth0 to eth1, because I have some old firewall script and I need eth0 be eth1, because of routing internet. My ISP close my net connection on MAC adress.

I am trying to setup linux box as router.
What i am trying to do is:
1. I am trying to setup NIC via network not NetworkManager
2. I have assigned the ip to both NIC with #ifconfig eth0 192.168.1.1
3. #Ifconfig shows my nic and ip
4. restart the service network .
5. #ifconfig shows nothing. NO NIC card
I dont want the network manager coz i dont want to install the gui on router and network manager works only in gui mode. ( i think my this understanding is correct)
I tried to configure the NIC with Network Manager
When ever i restart the network service i have no out put from ifconfig
I tried to configure the NIC with #setup command as well and select the dhcp option
I can not find any ifcfg-eth0 in /etc/sysconfig/networking-scripts/

I've got a machine running 9.10 with two network interfaces, one being motherboard based (atl1) and the other in a PCI slot (e100). By default at boot the interfaces come up in the wrong order. I'd prefer to have the e100 come up as eth0 instead of eth1. And then have the atl1 come up on eth1 instead of eth0. Both interfaces use static addresses and IP4 routing should be active across them. Where do I configure things to force the specific settings?

I'm trying to set up my cell so I can use cellular internet in ubuntu like I do in windows. I've scoured the net, and found multiple guides, unfortunately, the problem I'm having seems to precede any of these. I can't follow the guides because I can't get to the first step. When I plug my phone in via USB, whether I'm using the internet sharing program or not, I see "eth1 connected eth1 disconnected" pop up over and over and over.
My /var/log/messages reads:
Code:

I have a linux machine with 2 ethernet ports(eth0 and eth1). eth0 is connected to a router which assigns it an IP address 192.168.1.2. eth1 is connected to a switch and I assigned it an IP address 192.168.1.254 using "ifconfig eth1 192.168.1.254 netmask 255.255.255.0 up". How do I ping eth0 from eth1?
