VGN-SR490 / Linux - Missing Eth0 Ethernet Interface In Ubuntu - Can't Connect To Router
May 6, 2012
I'm having trouble getting my Ubuntu 10.04 machine (Sony Vaio VGN-SR490) to connect to the Internet by way of an Ethernet cable connected directly to my router. I'm able to connect to the Internet using this same cable using a Windows machine, so there's something wrong with the way Linux is configured.
Here are my network settings on Linux:
$ ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1
[code]....
It looks like the network adapters list is empty. I will now install both Windows XP and Ubuntu Linux dual-boot. I'm still not able to access the internet, even through Windows. I'm wonder if this could be a hardware problem with the computer or a problem with the router itself. Other computers can connect to this same router, and work fine.

I have my wan connection on the eth0. The bandwidth is 2mbps. I am running qos on that interface saying 192.168.200.0/24 can use 80% of the bandwidth and 192.168.201.0/24 can use 20% of the bandwidth. I Also have vtun VPN inteface to our branch office. I also wan to run some qos on that interface. How do i go about allocating the bandwidth on this interface? it is actually going via the eth0 interface, but the system actually see's it a an independent interface on its own right, so it requires it's own qos policy.

I've been reading for the past hour about opening ports on Ubuntu 12.04 and I can't seem to get anything to work. I'm running a program with an RPC server accepting local connections on localhost (127.0.0.1) which has allowed ip range 192.168.*.*
I've tried to edit the iptables to allow incoming connections, but curl still can't connect to the RPC server no matter what I do.
$ sudo iptables -A INPUT -i eth0 -p tcp --dport 18332 -j ACCEPT
$ nmap -v -sT localhost
Starting Nmap 5.21 ( http://nmap.org ) at 2013-07-13 05:54 UTC
Initiating Ping Scan at 05:54

I'm trying to get a Curl Response from an outside server, however I noticed I cant neither PING the server in question nor connect to it.I tried disabling the iptables firewall but I had no success.My server is running behind a Cisco Linksys WRTN310N Router with the DD-wrt firmware Installed. In which I already disabled the firewall.
Here are my network settings:
Ifconfig
eth0 Link encap:Ethernet HWaddr 00:26:b9:76:73:6b
inet addr:192.168.1.120 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::226:b9ff:fe76:736b/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
[code]......
This gets an empty result array. This function however works well in the previous server where the script was hosted before. No modifications where made whatsoever

I am using Scientific Linux 6.2 (Variant of RHEL / CentOS) . Every day at a particular time there is a power outage at my place, and after 1 hour power is restored. My laptop is connected to a network switch, that has no Backup power, and connection is disconnected when power is gone. Laptop keeps running in battery power.
Now when power is restored, the ethernet connection (eth0) is not automatically restored in linux. It only says connection available under wired connection. The same thing happens to the Wireless Network Connections. What can I do to automatically connect to these networks, whenever they are available?

(Setup routing and iptables for new VPN connection to redirect **only** ports 80 and 443) Only my goal is a bit different. I am running a headless gui-less install of Ubuntu Server 12.04 that is being used for a variety of different purposes... I would like all traffic to travel un-prohibited through my ISP except for my transmission traffic. I have a VPN i subscribe to that allows me access for which I only want to direct a single port's traffic to. I am currently using a modified version of the code from the above link. My current code is below:
#!/bin/sh
sleep 200
DEV1=eth0
[Code].....

I want to connect two laptops for experiment purpose. I do not want to use the internet on any of them , just be able to ping from one pc to another and SSH into them. The use is basically for a mobile robot , one pc on the robot and another one to control and see the processes using SSH. How do I use a wireless router to create such a network? I am using Ubuntu on both system (I tried ad-hoc but its not working).

Made a big mistake - Installed 64 bit Win7 professional on new HP that had 64 bit Win7 Home premium on it. Computer was a gift, bought as the last one available and was a demo model from Sam's club. Had no idea the ethernet card driver and the wireless software drivers would be lost, but they were, as was the driver for the USB hub. (Used an HP OEM disk purchased on line from Mountain software.)Where to get these drivers, and which ones do I need?

My hard-drive crashed, and I bought it refurbished, so I never got a Windows disc. I got a hard-drive from a friend, and I am trying to use it with my laptop, but it is missing the Ethernet Controller, Network Controller, and the PCI Controller drivers. I have searched all around, and I can not talk to Acer, for my warranty is past. They just want to repair it.

I just formatted my hard drive and installed Windows XP from scratch. I have a Dimension E310. When I looked at the Device driver menu I saw that I didn't have an Ethernet Driver installed. I have looked all over Dells site for the correct one but, can't seem to find it on the list for my Service Tag model. Possibly I don't recognize the drivers terminology as far as the list is concerned?
I have the original Dell Resource instalation disks with various drivers on them but, I can't seem to work out how to use them.

Needing to bridge from my wic interface to an ethernet interface on a 2900 series router so that I can pass through the ip address given to the WIC, to my ASA so that I don't have to give my ASA a private range address. (Just like a service provider might do when bringing a T1 with managed router in to my prem)

I just loaded the web interface IOS on a C3750X. The first thing I noticed was there was basically no web interface. I can look at things, and do default configurations on ports, but it doesn't appear I can configure VLANs or QoS or anything like that.
Am I missing something, or is this just how the web interface functions?

Whenever I plug in an ethernet cord into the integrated ethernet port in my laptop, I do not get a connection and the "Local Area Connection" icon doesn't show up in the Network and Sharing Center or the Device Manager. When I do plug it in, the "Local Area Connection" icon shows up for a second saying it's unplugged and disappears. I have tried different ethernet cables as well as an ethernet adapter (which does show up in the Network and Sharing Center, but I still don't get a connection).
My laptop is a Dell Inspiron N2010, I'm running Windows 7 Home Premium 64bit, and my ethernet port "RealTek PCIe GBE Family Controller".

Region : Others
Model : TD-W8901G
Hardware Version : V6
Firmware Version : 6.0.0 Build 120213 Rel.30335
ISP : ETAPA
I am writing in from Cuenca, Ecuador. I have a TD-W8901G Wireless ADSL2+ Modem Router. I have accessed the interface using the default ip address:192.168.1.1.When I select Interface Setup from the menu, it only shows Internet and LAN as the only 2 options. Wireless is no longer there. It just disappeared! The LED indicator light for WLAN is also "OFF." When you try the Quick Start wizard guide, it cannot complete the setup because there is an IP address error.
I have changed the firmware 2x since, trying to remedy this, I have also tried factory resets at least 3x. Nothing has worked up to this point.

I keep getting disconnected from the game "Vindictus". I'm not sure what protocols it uses, but it shouldn't require any configuration on the Router, since it was working fine before. I upgraded the firmware to 4.13 in an attempt to fix the issue, but it didn't work. Some people have suggested "Endpoint filtering" to be set to independent, but I cannot find such an option. Where is the option? I was told it was on the Firewall page, but it is not there (Advanced->Firewall/DMZ). The router is supplied by Virgin Media (ISP) but I'm not sure if that matters.

I have a new PC with the Windows XP 64-bit OS. When I attempt to connect it to my home network, it doesn't see the network, and other computers can't see it. The network card driver is a 1394 Net Adapter. The driver appears to be working correctly, but it's not getting packets in or out. The setup seems to be missing the required Q0S Packet Adapter, but Windows won't let me install it.

We want to terminate new 10M link via Ethernet interface on Cisco 1841 router. We have free Gig port on the router. We also have HWIC-FE module inserted in the router. However, our implementation team said that Cisco 1841 doesn't support 10M link. It is not designed to cater to such high Bandwidth.

I have a Cisco 4402-25 WLC with the below information that is having an interesting issue. When you log into the GUI interface with the local account and click on WIRELESS, then choose a accesspoint it brings up a menu where you have three buttons below for the following options (Hardware Reset - Reset AP Now), (Set to Factory Defaults - Clear All Config), and (Set to Factory Defaults - Clear Config Except Static IP). The problem I am having is we access all of our WLC's using Radius and when you enter your AD username and password and go to bounce a access point the GUI interface is missing the buttons, they however appear fine when logged in with the local account.

I've finally made the jump into Ubuntu and put it on my laptop. I have never used Linux before so it will be a bit of a learning curve although it does look quite user friendly.
I have already connected my Ubuntu laptop to my wireless router so I have internet. I would just like to be able to access files on my PC and vice versa similar to Windows Homegroup but I have no idea how.
PC = Windows 7 Ultimate - Laptop = Latest version of Ubuntu (I think it's 11?)
