Ubuntu Networking :: Browse The Internet It Will Not Connect To Any Pages
Oct 20, 2010
I just installed a fresh copy of Ubuntu 10.10 on a HP DV2500 laptop. Everything installed as expected but I am having some wireless issues I was hoping somebody could assist me with. I am able to connect to my network via wireless with no issues. However, when I attempt to browse the internet it will not connect to any pages. Obviously when I connect it via CAT 5 all works as expected. Any ideas on how to solve my wireless issues?
I know this is not a win-doze forum but i always ask my questions here so here goes.I am having what appears to be a DNS problem on a friends laptop. He is running windows XP. I CAN connect to networks and even ping websites but i CANNOT browse in Internet Explorer or FIrefox.
I have installed ubuntu a few times in the past but if I've had to get messy with the command line I bailed. So given that I wanted to set up a home server/media center, I tried win server, but given research had told me that it is easier to accomplish all the features I wanted with Linux I decided the time had come to really see what I'd been missing out on. So what I am looking to accomplish is a full lamp stack, xbmc, samba, mail server, VMWare server, rtorrent, ftp, an probably a few others I have forgot because I can't get to my check list right now. Settled on ubuntu 10.10, had installed it a couple of times while it was still in beta, just to get a feel for it and get everything working so that when it was released I could do a fresh install knowing how to configure everything.
So on Sunday the time came. Everything was going fine until last night, I was installing roundtable webmail and all I came to download something and FireFox can't display any web pages, postfix can't deliver mail. The server can ping local machines but not google.com or another internet site, I can ssh into it an get a remote desktop session via various methods, both either over the local network, or internet. The website is getting served both locally or internet. I just cant seem to make any outbound connections to the outside world.
I'm connecting to a network via a Belkin F7D1101. The adapter appears to be working fine, as I can see various wireless networks available and I am able to connect to my personal wireless network. The problem is that even though I am connected and have a valid IP, I am unable to browse the Internet. I can't even ping the router!
I initially thought it may be an issue with WPA, but I have installed wpa-supplicant and as a means of testing, I turned off WPA on the router, and the issue still stands.
Every thing was running ok in debain squeeze, but last time when i boot the system and connected to the Internet with the dialup connection, the graphical browsers like firefox and epiphany stop working and cannot open the web pages, the error is " Problem loading page", other clients like nslookup, ping, ftp clients and text browser lynx working ok.
I hope someone can help me as I am new to Linux and Ubuntu. I am running Ubuntu 11.04 and am trying to get VPN working properly with the pptp protocol. It is connecting but I cant seem to view folders or start a RDP session. I have tried this out with a Windows and a Linux machine and both work. The Linux machine was running Mint 10, in the vpn configuration I had set the gateway, user and pass, then in advanced mschap and mschapv2 were selected as well as mppe, allow bsd, allow deflate, and use tcp header. These settings work fine with Mint but its not working for me using Ubuntu. I did try to ping, sometimes it works sometimes it wont.
From today, I am unable browse internet using Fedora 10. Before this, I was using net in F10 with no problem, F10 was automatically configuring for net settings. But now I cannot connect to internet in F10, but I can connect to internet using windows xp. I have ADSL modem which automatically connects to internet when it is switched on. When I press any site name in Firefox it won't display any thing (in status it shows done).
And even following command not works. Code: ping www.google.com
But following command works fine ( I know yum search for software in repo using internet). I wonder how this commend works, while I cannot browse web. Code: yum search player
(I am completely dependent on linux). One more thing before occurrence of this problem I had installed xmms, xmms-mp2 and xmms-skins. I don't think this created problem.
I'm using FC10 on my box at work. It is behind an anthenticated proxy for internet connection. In Gnome, I configured the Network Proxy through the GUI, as my browsers too.
So I can browse internet pages, install packages thru Add/Remove Software GUI, but I cant do it in the command line, using yum install, for example. Then trying to figure it out, I saw that it cant reach the package mirrors. It isnt a DNS problem, I set the /etc/resolv.conf correctly, as the host command works correclty. I can ping the local pcs on the network too. Firewall is disabled. Below some simple tests:
[rtovo@davinci ~]$ ping mirrors.fedoraproject.org connect: Network is unreachable [rtovo@davinci ~]$ host mirrors.fedoraproject.org mirrors.fedoraproject.org is an alias for wildcard.fedoraproject.org.
A few days ago my wireless windows vista computer internet was running slow so i reset the modem. Then I went on the internet on my ubuntu machine machine and went to www.google.com and couldn't connect to the server so i tried linuxquestions and i couldn't connect but i could ping sites. My wired and wireless windows computers worked fine. So I called Comcast (my ISP) and said it was a router issue. So I looked online and it said to disable IPv6 on firefox so I did but that still didn't work.
I have openSUSE 11.2 64-bit KDE, I have installed it with lan cable connected, install updates and than switch to wireless.Everything worked great until I went to my girlfreind with laptop, there I can connect to router, use Skype but can't browse pages with firefox, can't install packages with YAST Also wired connection gives the same result but her PC have no problem with Internet.I have traied ifup, deleting /etc/resolv/conf, disabling NetworManager routing options with no succes
I'm using VPNC to connect to a remote cisco network, however I cannot browse the internet after the tunnel establishes. I know this is a DNS issue, as I can ping external address by IP (e.g. google). I can also communicate through the VPN tunnel without trouble.
/etc/resolv.conf gets updated by the VPNC with the remote networks DNS Servers, but I still cannot connect to the internet. I even manually tried to add my local nameserver to the /etc/resolv.conf file, without luck.
Also, just as a side note, I can only establish the tunnel via the command line "vpnc" command. I'm using Fedora 13 with KDE, but knetworkmanager / networkmanager will not establish the tunnel, however I haven't really dug very deep as to why. I've just setup some vpnc config files for loading the various connections manually, as needed.
I have 2 machines both using U 11.04, one of them being Studio. I have tried to connect them together (via a modem/router of course) to browse files but I can't connect. I get error messages. I've installed samba and everything.
A couple of days ago I Obtained a spare computer and installed fedora 14 on it, just to try it out. I only have experience with microsoft windows so I'm new to this system. The OS seems to work fine but I can't browse the internet with firefox. I'm using a speedtouch 546 v6 modem with adsl(wired). The network manager indicates that the wired connection "auto eth1" is active. The previous OS was windows xp. I was able to browse the internet whit this OS. I removed it because it was crashing all the time (illegal version).
I can connect to anything locally, I can SSH in locally but nothing works from outside my network (can't access pages in apache, can SSH, etc.) I've checked the logs I can think of, but what should I be looking for? The last thing I did today was add a FW rule to log and drop from an IP, saved my iptables to a file in /etc. (this was at 10:45am). The last time I successfully logged in remotely 1:03pm. I connected multiple times in between. I've rebooted remotely once or twice. That's it. I've already flushed iptables.
fedora (iptables) eth0 -private :192.168.1.1 eth1 -public : 126.96.36.199 squid proxy 192.168.1.10:3128 my clients range 192.168.2.0/24
how can i make my clients to browse internet only from proxy server my network is NAT 'ed. Please specify a iptable rule to allow internet access for my clients to browse ONLY if they come through proxy server.
On this box I have Two seperate Ubuntu installations. Recently in both I seem to be having the same problem. I initially can connect to the internet as per normal and use any internet application. But after a period of time, sometimes just minutes, sometimes hours, even though the icon says connected, I cant update pages or send emails etc because there is no actual connection. My Physical connection is good I know - My Ubuntu laptop and Windows gamming PC connect fine during this period. So
Does this suggest an intermittent hardware fault or is there some thing in Ubuntu I can check to make sure that it is setup correctly and nothing has been corrupted? I am a lay PC person - I dont really want to be command prompting - Plug & Play and Point & Click is my limit.
I tried to install Xubuntu 10.10 Maverick as dual boot on my laptop. However when xubuntu is on, I can't find a way to connect to internet. When I try the 2 arrows on the up-right corner the option for wireless is deemed. I tried offline/online, that did not work either. when I click the firefox It says you are not connected.
I am trying to setup a dhcp server for my internal network. I have two NICs, a modem, and a wireless router. I have my server connected directly to my modem which is providing me with Internet access on eth1 and is working fine. I have dhcp and dns setup on eth0 which is connected to my router. The router shows that it is connected to the Internet but when the router gives a client computer an IP address, the client is unable to connect to the Internet but can connect to the router. I will post my configuration files below with my current configuration.
I can connect to the internet through wifi, but I cannot connect to anything on my network. I have a printer and a NAS, so I would really like for this to work again. I have a dell laptop with a Broadcom card.
I have a fresh install of CentOS 5.5. I am trying to browse to the Windows machines on my network (Places > Network Servers > Windows Network), but I get a blank window. I am able to ping the Windows machines using their IP address, but not by their name. What do I need to do to be able to see the Windows machines and also to connect to shared folders on these machines? So far I have tried starting SMB (via System > Administration > Server Settings > Services). I have also tried changing my smb workgroup to "WORKGROUP" (the default was mygroup which did not match my Windows machines.
I had put my computer on standby and when i restarted it, it powered off within a few seconds. I turned it back on and after that i've lost connectivity to internet on Ubuntu 10.04.
However I have VMware (XP) installed and internet/network works on that. I'm a newbie with Linux.
Here are some outputs:
I have tried to edit the connection using System>Preferences>Network Connections. I entered manual settings for IPV4, but whatever i enter there, it doesnt get reflected when i type ifconfig in the terminal window. I tried setting it to Automatic DHCP as well. Doesnt work.
I've recently set up a local development webserver using Karmic Koala. I downloaded and installed the server version of Kubuntu and have the web server working.
The problem is that for some reason, I'm no longer able to connect to the internet. I can connect to my router, and other machines in my network can VNC into the server.
I'm using an wired connection to the router and have the server set up on an internal IP of 192.168.0.100. I used to be able to connect to the internet, I downloaded and installed a load of packages etc before it stopped working.
The last thing I remember doing before it stopped working was that I installed Samba so I could share files with the other machines on the network (two Macs running Leopard and a WinXP laptop).
I got the share working - I copied a load of files to the server via the share, rebooted, and for some reason now I can't connect to the net (and other machines can't see the Samba share either.) However I can still VNC into the server.
I've always been a big fan of linux having used it extensively in the military, came across a really nice looking distro called ubuntu 8.10. I installed it along side Vista on my hp dv7-1170 laptop and dual boot. Worked like a charm found all the drivers for all the hp devices including the webcam bluray etc. So I decided to put ubuntu on exclusively and just run virtualbox ose and put a vista session on there for when I needed it.
So I did that no problems, went and installed all the updates. Between the time I installed the updates and downloaded and installed a server patch to allow it to use all 4gb ram, I lost my inet connection. which was wireless. So I plugged into cat5 outlet and nothing. Just won't get an IP, so I wiped it again and reinstalled. Now I still can't get an IP from wireless or eth0. I can manually assign it an ip and it says connected, but still don't get out.
Few days ago i installed ubuntu 11.04 on my PC everything is fine but no sound at all, I am going to ..... and playing a video, a video started playing but no sound, i have just installed ubuntu restriced extras bun not working.. i really need sound..
