Ubuntu :: Steps To Access The Internet ?
Jan 13, 2009
My suse 10 os is old and not supported any more. I only use my windows xp to write letters and the space in my computer is getting thin. I have a Ubuntu D5427 disk that I am going to install soon into my computer. The only worry I have is how to use Ubuntu to access the Internet.
I had to buy and use an external modem for suse. Does Ubuntu require an external modem?
Does Ubuntu have a special section for configuring a dial-up connection?

I am having some problems getting my Ubuntu connected to the internet via VMWare. I use a wireless internet connection on Windows 7, however when I boot Ubuntu, it tries to connect to a wired connection called "Auto eth0", It says that it is connected to "Auto eth0" but when I try to open Firefox, it tells me that I do not have an internet connection. I have tried setting up a wireless connection but that does not appear to work either.Is anyone here willing to help me take the necessary steps in order to get myself connected to the internet through my VMWare?

I have a linux box (fedora) with two ethernet cards eth1 and eth2. On eth1 I successfully configured a PPPOE internet connection. Such that from the server I can browse the internet. On eth2 I wired it to a wireless router essentially to provide the wireless cloud. On eth2 I also configured dhcp, such that the Linux box is both PPPOE and DHCP server.However my clients on the LAN cannot access the Internet.
On passing the routing command I get
Destination Gateway Iface
196.44.x.y 0.0.0.0 ppp0
192.168.1.0 0.0.0.0 eth2 (my subnet)
0.0.0.0 0.0.0.0 ppp0.
The router (functioning as a wireless access point mainly) has a fixed IP address of 192.168.1.2 and eth2 has IP address 192.168.1.1. The dhcp file running on Linux has been set with option router (Gateway) 192.168.1.1. I cannot figure out how to correctly set the routing table such that my clients on wireless can access the internet cloud. I googled and googled but no solid solution. Any suggestions?

I managed to configure my W890i phone to get access to internet through an ubuntu-based computer. It's very easy to use the phone to give internet access to the computer, but the opposite is quite more tricky. For that I've done the following
----On the phone---
-Set the USB network option to "through computer", so that the phone uses the computer's internet connection and not the opposite.
-Decide and set "Shared Network" parameters: user, pasword and workgroup.
-In "conectivity-> internet connection" set "allow local network" to "yes"
----On Ubuntu 10.04---
-Install samba, samba-client, smbfs, smbclient, firestarter and dhcp3-server
-Configure Samba (System-> Administration-> Shared folders): same workgroup as in the phone, add new user (the phone), passwd this new user. In my case the user was called "w890i" and the password given was the same.
-Once the phone is connected to the computer through USB (then select "phone mode"), a new connection appears in NetworkManager: usb0.The aim is to create a shared network that gives internet access to this device. Edit the IPv4 parameters of this new connection, set them to Manual and give an IP adress (192.168.0.1) and a subnet mask (255.255.255.0); the rest of the fields are left empty.Connect this network.
-Set firestarter to use dhcp3: sudo ln -sf /etc/init.d/dhcp3-server /etc/init.d/dhcpd
-Launch firestarter and follow the wizard. Set "allow internet shared connection", choose the device for the primary internet access, and then the device for the shared network (usb0). Then change the settings for firestarter: activate DHCP for local network, set IP to the one we gave before (192.168.0.1).
-Open dhcp3-server config file sudo gedit /etc/default/dhcp3-server And set INTERFACES="usb0"
-Set the policies of firestarter: in incoming connections, allow connections from the IP adress given to the phone (192.168.0.1). Then add rules for the ports that need to be open for this connection. I opened HTTP, HTTPS, SMB, SMTP, POP3, IMAP, IMAPS, DHCP for all the connections in the local network.
-Apply policies and start the firewall.
------------
After all this, the phone can access the internet through the computer. Two problems appeared:
1. I couldn't get access to https sites, like webmails. The phone gave a "communication error". But then I tried with Opera instead of the browser built in the phone's firmware, and I could finally get to https sites.
2. I couldn't retrieve mail, neither POP nor IMAP nor IMAPS. I thought it was a firmware problem again, and I tried out several mobile phone email clients written in java, but none of them worked.
So this is at the moment the problem. If I connect from the phone to the internet directly through 3G, the email clients work for all my accounts. I don't think it's a firewall problem, because the ports are opened for this connection

I installed 11.3amd64 as a VM under Vista/VMWare Player - all worked fine. I have now installed it as a physical system. It nstalled cleanly BUT during first boot it could not access the repos. With each repo it gave the message
- download (curl) error for (repo)
- error code connection failed
- error message could not resolve host (repo)
This was followed by a message box containing
- UI syntax error
- no widget with ID 'contents
Firefox could not access the internet (cannot find server) until I disabled IPV6 (I used about:config), now it works fine. I think the repos problem is because of IPV6 - I usually have trouble with IPV6. I tried disabling IPV6 with the following (How To Disable ipv6 on SuSE Linux | Linux Poison)

I have an old FC2 box running Squid version 2.5. It has been running since 2003 so I am in the process of replacing it. I have a new machine with FC11, iptables, and Squid 3.0 installed.
On the old machine I use iptables to intercept Port 80 traffic and send it to Squid. By default I block all internet access and allow only sites that are in an Allowed_Sites.txt file. Within Squid I also have statements to allow certain users to bypass Squid based on their IP address.
I have set up the same thing on the new box. I have iptables intercepting the Port 80 traffic and sending it to Squid. That is working because if I remove the redirect statement from iptables all internet access is blocked.
The problem I am having is that Squid is not blocking any websites. It acts like the ACL is set to http_access allow all. I have worked on this for several hours and am stumped.
These are my Squid rules:
acl allowed_sites url_regex "/etc/squid/Allowed_Sites.txt"
acl manager proto cache_object
acl localhost src 127.0.0.1/32
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32
acl SSL_ports port 443
acl CONNECT method CONNECT
http_access allow manager localhost
http_access deny manager
http_access allow Bypass_Users
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
acl our_networks src 192.168.1.0/24
http_access allow allowed_sites
http_access allow our_networks
http_access deny all
icp_access deny all

Problem: Using ubuntu 9.04 64 bit, attempted to install wireless card to desktop. Wasn't able to get wireless to work, now LAN isnt working.
I am unable to use the internet from the desktop (mozilla, update, ping, etc) BUT the strange thing is that I can NX nomachine into my desktop.
This boggles my mind, I can get in via the Nx but am unable to get out. So I know my lan card is working.
Question: I must have changed a setting when I was goofing around with the wireless install (via network, network tools). Is there a way to 'flash' my network back to fresh install? In other words, how do I restore it to its previous unconfigured setting.

I have installed UBUNTU 9.04 as dual boot with XP. But I can't access internet through it because (I assume) UBUNTU has no driver for my USB ADSL Modem(PROLINK H9601).
I have surfed the web and yet got no relief. I even wrote to the Prolink vender and they to confirmed that they yet don't have any drivers for ubuntu.

I installed Ubuntu 9.10 onto a machine a few weeks ago, and that machine had internet access, so it was easy to run these commands:
sudo apt-get update
sudo apt-get install openssh-server
sudo apt-get install portmap
But now I need to install Ubuntu onto a machine with no internet access. How will I be able to install openssh-server and portmap?

Note: Not upgraded yet, still using Ubuntu Lucid Lynx.Recently I've had a strange problem with my internet connection. When downloading something I am unable to use the internet with other net clients. An example, this morning I was downloading a very large set of backup files from an online server where I store backups. The files totalled 1.5 GB and I was downloading them using a SFTP client called FileZilla - during the download I was UNABLE to access the internet using Firefox, pages did not load at all - NOT slowly, but NOT at all, the "can't find the server" message was displayed by Firefox.LikewiseThunderbird was not able to check/download email. Confirmation that no internet access (other than FileZilla) was possible was shown by trying to 'ping google.com', the response "ping: unknown host google.com". During all this FileZilla was downloading very happily and quickly and as soon as the downloads finished everything worked as normal.
The problem is not limited to FileZilla, when downloading a file with Firefox the same problem occurred. It is as if when downloading something all other net connections are put on hold including DNS lookups. In the past my internet connection might slow down as a result of downloading but I'd still be able to access the web and email just slower as a result of the download. This problem has only started happening in the last week or thereabouts.

Ok i want to access my server from internet, ok I have checked with my mobile internet provider (3) they say they dont block any ports, is it just a case of letting the firewall let external access to pc? ( no router just mobile dongle)And do i just ssh into external ip on ssh port

I just installed Ubuntu 10.10 today on my laptop (I installed it alongside Windows 7).
My problem is that I'm unable to access the internet; actually, I'm unable to access any wireless connection at all.
I'm using a Linksys Wireless-G Notebook Adapter (2.4 GHz) in my laptop.
From what I've read, normally, many wireless cards are detected by Ubuntu automatically when you install it. However, this did not happen with my card.
...So, I'm not really sure what to do in order to gain access to the internet.

I've got VPN setup and working on my server. I can VPN into the server and access my local network from anywhere. It uses pptpd for it. My problem is that I can't access the internet once I'm connected to my VPN. Is it possible to allow internet access through VPN?I mainly would just like to be able to connect, access my local network, and still browse the internet. Is there anything specific I need to change?

I can access dirac.org from inside my network; I can't access it from outside my home network. Apache is running on a Ubuntu box named "satan": 192.168.0.2 and I'm testing it from a MS Windows machine named "lucifer": 192.168.0.3. My ISP is optimum online, which does not filter port 80.
0. router
The router is a Netgear WNDR3700. All computers on my LAN receive their IP addresses via DHCP, but I've reserved all the IP addresses, so they are essentially static (satan is always 192.168.0.2, lucifer is always 192.168.0.3, etc). The router is set up to pass packets destined for port 80 to satan (192.168.0.2), which is where Apache runs.
1. tcpdump
Using tcpdump when accessing dirac.org from within the LAN (this is what works):
# tcpdump -i eth0 host ool-18bda2d2.dyn.optonline.net and tcp port 80
ool-18bda2d2.dyn.optonline.net.2826 > satan.www: Flags [S], seq 3934453911, win 65535, options [mss 1460,nop,nop,sackOK], length 0

How to access internet using above CD? I normally connect through dsl/wired connection/static IP with router and modem. I'm not sure in livecd if I use pppoeconf in terminal (which returns "access concentrator" fault) or if I first configure it within System/Network for static IP.

I am about to setup my WLAN which sadly isn' that easy. I have followed some instructions which use the wpa_supplicant for the WPA setup and router connecting. In this example the tutor uses a -Dmadwifi flag. Well, I am sure this works for many users, but obviously that madwifi is not MY wlan driver. So, actually my quite simple question: how can I find out my driver's name?
btw: wlan works, I succesfully connected to a non wpa/unsecure wlan router (I can't use it for surfing though. Trying -Dwext made the wpa_supplicant at least try to connect but without success. Well, maybe that isn't my driver either? Grepping for wext in /etc or dmesg to see if it actually IS didn't show me anything.
Also, I do not have hwinfo installed which is said to yield drivernames. Certainly, I cannot install it without internet access. So what can I do?

I can not access the internet from within ubuntu. I have tried pidgin firefox and ping but I do not get a reply with any of them. I do however get full access using Virtual Box OSE running Windows server 2003 running inside the machine. This is not a one off as I often have trouble connecting to internet from inside ubuntu but usually disabling then enabling networking works.
My system:
OS: Ubuntu 9.10
Wireless card: Edimax wireless 802.11b/g Turbo Mode PCI adapter.
Here is the corresponding bit from lshw:
Code:
*-network
description: Wireless interface
product: RT2561/RT61 802.11g PCI
vendor: RaLink
physical id: 0
bus info: pci@0000:05:00.0
logical name: wmaster0
version: 00
serial: 00:1f:1f:24:43:ca
width: 32 bits
clock: 33MHz
capabilities: bus_master cap_list logical ethernet physical wireless

resources: irq:20 memory:ea100000-ea107fff
I'm really confused as to why a VM would be able to access the net and not the host.

I have a Compaq Presario R3000 with Ubuntu 9.10 32 bit that I just installed last night. I'm using a Zyxel G-102 Wireless card and Actiontec GT701WG wireless modem.
When I try to connect to the 'net, the network does show up and it connects strong (100%). It also shows multiple neighbors networks. It pings at 99% success (with over 900 sent as I write this) but when I open Firefox it can't connect, it just times out. I've used WEP security and have switched off security as well. I tried hooking up to the modem via USB and get the same result. It acts like a Firewall issue but there isn't one installed - at least that I can find and the Firewall in the modem is off. I ran FF in root with gksu firefox as suggested in another thread. I tried www.ubuntu.com and the header loaded but that was all. Then it timed out.
I'm new to Linux but have used Puppy Linux with this machine and card, etc. so I know it can/does work with Linux. I wanted a more refined distro and chose Ubuntu.

Its been a few years since I gave linux a go but having just bought an acer revo and enjoyed xbmc on myxbox I thought I would give it another go.I downloaded the 64 bit version to usb stick and got to the desktop of the live install.Everything looks great but no internet access over both wireless and ethernet.I'm used to the wireless being detected etc in windows and even though I found what must be the network manager and put in my 64 bit wep code etc it couldn't find my wireless connnection.
I thought then that mabey the preinstall ubuntu doesn't do internet.Just to see if this was the case tried it with the netbook version on this I can get ethernet access but on removing network cable no access at all.I've got an old netgear router which I am replacing soon in case thats the problem.I don't want to install ubuntu unless I can get wireless internet/network access.Being a total linux newb some of the guides I've tried to follow on the net presume I have too much knowledge.So I end up getting lost.I go into wireless connections psecify name of network (SSID ie Wireless) put in the Mac code of my router and the 64bit WEP key. I don't touch the lpv4 and 6 settings as don't know what they do Still no joy
I wonder if anyone out there has a revo 64 bit version of ubuntu working and could help mme find my wireless connection.Just an update I reput the settings into the netowrk manager and it worked although very slow.Is this because its a live install. I'll now try it with ubuntu 64 bit and see if I can get access...I seem to be getting there although very slow

I'm running mac osx snow leopard 10.6.2, installed virtualbox, created a partition with it and on that I installed Ubuntu (looking more specifically, I found it is Karmic Koala). For one, is kubuntu ubuntu karmic like mine? Or is that something different? Anyways, Did all that, installed guest permissions and everything, but before that and still, when I load up firefox, I can search some google things, but whenever I go to an actual page or something that seems like it needs just a little more muscle than google searching, it just crashes and disappears. So I basically can't access the internet.
I even tried installing Google Chrome through the terminal by some tutorial on another site. It worked and I got it all installed. It does the exact same thing Firefox does. I can do a couple of searches (sometimes not even that before it crashes) but when I go any further than that, it crashes.

I have used other distros on and off in the past with no trouble, but for some reason I seem to have had this problem with several versions and flavours of Ubuntu on various systems. I've never solved this problem the previous times I've had it, just given up. But this time I actually need to get this working. I've recently upgraded my computer, so my old system has been relegated to HTPC duties in my lounge. I installed Ubuntu 10.04 and I'm having issues getting internet access with some programs, while others work fine.
Firefox and Evolution haven't been able to access the internet from the start.Empathy IM has no trouble connecting to my MSN and Facebook accounts.I had no trouble downloading and installing Google Chromium browser through Ubuntu Software Center, and have no trouble accessing the internet with Chromium.On the first boot after the install, Ubuntu automatically told me to update my nVidia drivers online, and did so without error.Update Manager detects updates, but fails to download them.
I successfully and flawlessly downloaded installed XBMC Media Center and some related skins and things through Synaptic, but XBMC cannot access the internet. However it can access shared files over my LAN, including Windows 7 shares.Ubuntu itself cannot access any files on my Windows 7 computer. It can access the work group and see my Win7 shares, but refuses to mount them. Strangely, XBMC can access these shares and stream media from them fine.

I recently installed Ubuntu 10.04 and it appears to be working fine except for one problem: the internet access does not work at all. It is supposed to connect through a wired LAN and can talk to the router but when it comes to opening a webpage or pinging a server it doesn't work. Firefox says that it can't connect and the ping does nothing.
The computer can connect fine when booting Windows XP, but on Ubuntu it can't. Here are some details about the two OSes:
XP: Connects to network and internet
Ubuntu: Connects to network but can't mount the 'Windows Network' folder which is the only thing in the Network directory. Can't connect to internet.
I'm on a Dell Dimension 2400.
