my internet was fine.. until.. i had to work in the school so.. a teacher configured the internet settings.. for something .. ( i don't remember) and everything was fine. but when i returned to my house and conected my lap to internet (cable) the internet didn't work.
I am running the latest ubuntu and I am having trouble getting networking sorted. I have 2 networks, one wired (eth0) and one wireless (wlan0). I connect to the internet using wireless. The problem is that I can only successfully connect to the internet if I disconnect from eth0. I have hit this problem with Windows machines and the solution was to adjust the "interface metric" in "Advanced TCP/IP Settings" so that the wireless was the preferred connection. How can I achieve something similar in Ubuntu?
I have installed the Squeeze testing version. i have setup networking for static in the /etc/network/interfaces file. tried to find resolv.conf in the /etc/ since could not find i created this file post trying to start the eth1 i am able to ping my ip, but if try to ping the gateway i get an error saying the ping is not sucessfull. I have 2 network cards, eth0 and eth1. as eth0 does not work i have configured eth1. The dump of the interfaces file is below
[code]...
The same setup works fine in Ubuntu 10.10 setup that i have.
I'll start by saying that most of this is built inside of a 64bit ESXi 4.1.0 server. Should be obvious by the picture below.
Trying to set up a bridged CentOS box. Ultimate goal is to set up a Transparent Firewall. The machine labeled 'Desktop' is a Windows XP running DHCP. It gets assigned an Internet routeble IP address. At this point, nothing is running a firewall.
Symptoms: Gateway can ping CentOS bridge CentOS bridge can ping gateway CentOS bridge can resolve DNS names and ping FQDNs on the Internet. CentOS bridge CAN NOT ping Desktop
I cannot get static addresses to work on eth0 and eth1. eth0 seems to use DHCP while eth1 uses the static information. Sometimes the static info is used but the interfaces get the addresses reversed.
From /etc/sysconfig/network NETWORKING=yes HOSTNAME=mosaic
I just upgraded from 9.04 to 9.10. When I restarted, I admired the new login menu, then went to Firefox. I noticed that my wireless didn't work (it did in 9.04) Thinking I'd just need to reinstall the drivers, I plugged in the computer to a working Ethernet outlet with a working cord. I noticed that Ubuntu didn't tell me that Auto eth0 was connected. It didn't tell me anything. And then I went to Google and realized that the wired connection didn't work either. Then I came here on an iPod Touch and you know the rest.
I really want to convert over to ubuntu and use ubuntu netbook remix on my new netbook but I've had a hell of a time trying to get it to access the internet, I've tried installing drivers but I don't really know how.
My Netbook Details:
MSI U130 1.66 Intel Atom N450 1GB DDR2 Ram Windows 7 Starter 802.11 bgn 1r1t Mini Card Wireless Adapter
I have a desktop pc with xubuntu 9.10 32bit installed. I don't have direct access to this machine, but they told me that internet is not working (firefox, synaptic,etc...), but only skype works! If they reboot on windows, everything works well, so it's not a matter of connection or dns.It's very important because they work with that computer. How can i solve the problem? and what could be the cause of this strange anomaly
I have a WUSB54GC v.1 wireless USB adapter which I use to connect to my home network. For some reason, over time my reception has been getting worse. I'm not sure if this is due to the router or the adapter. In addition, when the signal strength dips below 50%, I can no longer receive email or browse the web. This is only a problem with Ubuntu - when I had WinXP installed, I could access the internet mostly regardless of the signal strength.
I started a year ago with the adapter plugged directly into the computer. After a while I found it necessary to use an extension cord to place the adapter outside my room, closer to the router. A while later it was time for another extension cord, and now my reception has gotten worse again, but I can't extend it any further.
I'm runnig f 13 on my laptop, and it runs like a charm. But once in a while, the internet doesn't seem to work properly. It mostly works, but right now i am unable to reach certain pages such at google (which is annoying), whereas other pages like yahoo and this one works perfectly well.
I recently installed Fedora 15 x86_64 on my new AMD Machine and I'm quite pleased with things thus far.Here's where my problem comes. I mainly bought that machine to help me with Development. More specifically, Virtual Machines for testing purposes. I have installed Fedora 15 x86_64 as a qemu-kvm Virtual Machine and it's working.. for the most part. I am having a whole lot of trouble getting it to connect to the Internet.
My guess is the only way I'm going to reliably do that is to setup a Bridge. Yes/no? However, in order to setup a Bridge I need to disable NetworkManager and that where the fun happens. It completely disables my network connection. I'm probably missing something small, but I can't figure out what I'm missing. I've double checked my ifcfg-em1 multiple times(I've been trying for ~24 hours so far) and all the settings are as they should be.
I've turned NetworkManager off and stopped it(chkconfig and service) and turned network on(chkconfig and service). Theoretically I should simply need to turn off NM and turn on network and things should be fine. no?
I am a convert from Ubuntu (9.04 kept freezing on my laptop; when it did work, many packages it seemed were outdated--ie only Eclipse 3.2, rdesktop was messed up [and apparently is also in Fedora]), and I am having some trouble with getting my wireless working.I am running Fedora 11.First off, there is a problem when trying to connect when using DHCP. NetworkManager gets to the second green dot, and then after a short while I am given a message that the connection was disconnected.
Configuring the interface manually, not using DHCP, allows the connection to complete. However, the internet is very slow. There is a 15-30 sec delay before website loading actually commences, and then another delay each time an ad must be fetched from another server.How can I fix this delay? I know I have encountered it in earlier versions of Ubuntu, but I can't remember how I fixed it.About the rdesktop problem, if anyone is able to help [maybe I should post another thread?], the cursor color (the color of the pointer) is inverted---where it should be white it is black, and where it should be black it is white. I use rdesktop a lot to connect to my terminal server in my basement. Any idea how to fix it?
My network name is eth2 it was changed by some reason and now i got these errors... i installed, reinstalled, re re installed, tried to run the asistant but no luck :/
Code:

i was using ubuntu 9.10 till recently when i decided to upgrade to ubuntu lucid 10.04. turns out the internet icon shows connected after fresh installation but when i try to use firefox , after an long wait it shows server not found. i did a research of my own and found that i am not able to ping even my router.using sudo dhclient eth0 doesn't recieve offers , but surprisingly when i tried dhclient eth0 in root shell with networking internet got configured very quickly and i can ping the router and any website.i forgot to mention i have a wired connection which i am trying to connect and the net is working fine with windows 7 on the same PC.
I have two connections for my PC, my Ethernet which is on the corporate network and my smart phone on 'usb0'. Both have full internet access.I want to stop my PC from connecting to the internet over the Eth0 while still connecting to internal servers then just have internet over usb0.If I go to the settings of 'Auth Ethernet' in the tray area, under IPv4 there is the routings section - I've tried enabling "use this connection only for resources on its network" but it doesnt work.
im a linux noob dont get techy ill die of brain fry im running a craft bukkit minecraft server on my 11.04 ubuntu server. however the server uses my only 10m Ethernet cable that i normaly use for my ps3 (i will NOT go wireless. i hate it (or dont like it)) therefor i found an old PCI NIC in an old computer, its a 10/100 realtek one. ifconfig detects it (after two commands:
Code: ifconfig eth0 up dhclient eth0 )
now i need to send the internet to my ps3 too.i know the connection wont be blazing fast but isnt it okay?it musnt interrupt the minecraft server. if you need info just ask. ill try and provide them.
i want to share the internet connection from Laptop to PC via LAN crossover cable here's how i connect to the internet in laptop, and connected PC via LAN:
i need to share pppoe(ppp0) to (eth0) , that is what i've been doing in Windows before, but i dont know how to share in Linux, i tried to follow Ubuntu Help about ICS, but it doesn't work
My machine has Ubuntu 10.4, installed a week ago. I'm connecting to the Internet with a Wireless 3G modem, the interface is named ppp0. Additionally, I have a network card that is connected to a home router, that's eth0. Everything works fine with eth0 disabled, all my apps can access the internet correctly. But, my issue is that when i enable eth0, i can't access the internet with any app.
So why do i need eth0 anyway? The thing is that i must share my internet connection with my sister, who is also connected to our home router. I planned to give her access by installing squid on this machine and configuring her browser to connect to squid. However, since none of my apps can connect to the internet while eth0 is active (whereas squid and all other apps work fine with eth0 disabled) I can't let her connect to squid while squid is working correctly.BTW selecting "use this connection only for resources on its network" under "routes..." of the ipv4 tab of "Auto Ethernet" made it a little better. Firefox and Xchat started to work with eth0 active. Squid still doesn't work though (althought it works just fine with eth0 disabled)
I've got access to my LAN and the Internet via my wired ethernet connection. I'd like to share that access with my iPod Touch (device shouldn't really matter) via an Ad-hoc wi-fi network.
This tutorial in the docs seems to describe the right setup but is very out of date (7.04). Instead I found this tutorial and followed it to create the Ad-hoc wireless network. I was able to connect my touch to the resulting ad-hoc network without a problem, but I didn't have LAN/Internet access.What's the next step to get the clients on the ad-hoc network out to the Internet?I found this page in the docs that says I'd need to install dnsmasq-base and uninstalling dnsmasq. I checked and dnsmasq-base is already installed but dnsmasq is not. I do have dnsmasq in /usr/sbin but the package description makes it sound like this should come with dnsmasq. Is the page out of date? Will uninstalling dnsmasq cause other problems?
Since I have a new internetaccount, 2 days ago, I have a problem on my server [Fedora Core 8]. I use it as a router.
eth0 is for the internet. eth1 is for my LAN.
But since my new internetaccount my server uses eth1 for the internet. This is a line from my syslog:
Code: NetworkManager: <info> Policy set 'System eth1' (eth1) as default for routing and DNS. I killed the NetworkManager daemon and now it works but this must not be the way to do it? Where do I tell my server that I use eth0 for routing and DNS?
I created a F14 x86_64 guest OS in VirtualBox4 (hosted by F14 x86_64) and configured it to get its IP from my router but it won't do so on boot. The other guest OS's (Fedora 14 i386, 2x Oracle EL5) are able to get their IPs on boot.
I checked the setting in the network manager and they show that the interface is to be activated on boot but it doesn't. When I log in and run ifup eth0 as root it works.
I can't connect to my ssh-server (on ubuntu 10.04) from any external address. The error in putty is "connection timed out". From my internal network, everything works fine, even if I select my external IP address and port in putty as the destination.
This is what I have done so far:
installed open ssh with the ubuntu server 10.04 cd set up port forwarding (11041) in my router (seems to work ok, port is open according to "shields up") configured ssh to use port 11041 in /etc/ssh/sshd_config changed tcp and udp ssh port in /etc/services to 11041 enabled UFW and did sudo ufw allow ssh
I've a desktop running Fedora 10 connected to the Internet via LAN. There's 3 network controllers in the desktop. One integrated to the motherboard and two additional. I would like to connect other computers (two laptops, one running fc9 and the other Window$ XP) to the Internet via the desktop. I googled the question and found out that I need to adjust thing called 'NAT'.
For that purpose I did the following: iptables -t nat -A POSTROUTING -s 192.168.2.0/24 -j SNAT --to-source 192.168.*.* where 192.168.*.* - is desktop' IP address. I want to use 192.168.2.0/24 as a network for laptops. I activated one of devices (eth1), gave it IP address: ifconfig eth1 192.168.2.0/24 and connected f9 laptop to it.
On the laptop I activated eth0 with the same IP. The problem is: it doesn't work. I can't ping anything from the laptop except its own address (192.168.2.0).
I have a Proliant DL 120 G5 with CentOS 5.4 and I have installed a Brodcom Corporation Netxtrem BCM 5722 Gigabit Ethernet PCI. So I have two interfaces: eth0 broadcom eth1 Intel The eth1 works, instead eth0 don't work. I can ping itself and 127.0.0.1 but I can't ping the gateway. The results of netstat -nr is:
Everything worked fine until very recently, and without apparently ANY change to the settings on the server, a secondary IP that was assigned to my server won't work anymore..Any IP attached to the same server works fine.. So in my case, the problematic IP is 213.8.155.67. The other IP (213.8.155.42) works without any problem.How would I go about troubleshooting this?
ifconfig: eth0 Link encap:Ethernet HWaddr 00:26:B9:44:11:3A inet addr:213.8.155.33 Bcast:213.8.155.127 Mask:255.255.255.128 inet6 addr: fe80::226:b9ff:fe44:113a/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
I've just upgraded to Ubuntu 11.04. Everything worked fine, until I rebooted. Now I can not connect to my home wireless internet, so I can't re-enable third party software sources. I am currently using a different computer, so I know that our internet works. I checked the wireless switch on my laptop, and it says that wireless is enabled. I've rebooted, and it still doesn't work. I tried our wired internet, and that didn't work either (although I'm not sure if our wired internet works; we haven't used it in a few years)
