Ubuntu Networking :: Can't Access Any Internet Sites?
Jan 22, 2011
I am using Ubuntu 10.04, when connected to the ethernet through , Atheros Communications AR8152 v1.1.I can successfully access the internet. But when I try to use the wireless I can connect to the network using Atheros Communications AR9285, but can't access any internet sites. Or ping any other devices on the network.I'm using an Acer Aspire One D260
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
Strangest thing...yesterday my 11.04 box lost the ability to access anything external. I can ssh to the box from outside my network, and all other boxes on my network are fine, but this one box can't hit anything external. If I attempt to ping a site it's doing the same resolution, but no packets are delivered.
Up until yesterday it was running fine, and I didn't make any changes to my home network or install any updates. Totally stumped.
Edit: this is a wired connection with a static internal IP.
DM9, 2GB RAM, 32GB SSD, Ubuntu 10.04 UNR.At Panera and at my local library there is a page that comes up when I try to connect to the Internet that is an agreement page. It comes up with my iPod Touch and with my MacBook. Using my DM9 that page does not come up for me to sign in so I can't get on the Internet.I have had Firefox and Chromium running at different times with the same results. When there is a WEP password or no password it connects. What do I need to do to get connected to the Internet at Panera and the like?
I see something like internet connection is established. Ive established etho connection but I cant open any sites at all. I also have Windows on another hard disk and it works well. About a week ago I had Ubuntu 8.04 and it worked really fine. What�s wrong? Is there any remedy?
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.
Unable to access our site via eth0. Can access the same site, via same ISP on wireless laptop, or via eth0, but using ip annonymizer service. Have a feel that it could be something obvious, but after digging through Modems firmware I am running out of ideas
I have a question which it believe it is quite simple but I have no clue how to do it... I'm using Fedora 12 and I'm the only Linux machine in my office's LAN... I have Apache (httpd) setup and my co-workers can access the sites perfectly by using my IP address, for example [URL]... So here's the question, how do I setup a domain name so everyone in the LAN can access the sites by typing [URL]..
I am in China, where some web sites(....., facebook, etc) are blocked. So I have to access these blocked site by VPN. But how can I access blocked sites by VPN and unblocked sites by my direct ADSL?
I connected my laptop running with Ubuntu 11 in the LAN but I couldn't access internet.But I could ping to the other computers connected in the LAN. I tried the same thing with windows 7 in the same laptop and I could access internet.
I installed CentOS. NetworkManager successfully installed and launched. I can ping any IP from terminal but I can't open any site in browser except 127.0.0.1 I can't open IP of the modem 192.168.1.1 in browser also.
Im having trouble using my wireless usb dongle. I've installed the software and connected to the web, but i can only access a number of websites.
I can access ....., and watch vids and perform searches on google, bing, yahoo and the like. However when i try and access a site that i have searched for it takes me to the internet providers homescreen and tells me to activate my account or top up my account.
I know i have enough GB left as i recently activated my account and i'm able to use the wireless stick on another computer without any problems on all websites. So this leads me to believe that there is maybe a problem with my browser or security settings, but im not sure what to do.
I dual boot XP and FC14 and have 2 routers. I can connect and ping one of these routers when I'm in FC and I have an IP address I just can't load any websites. When I connect to the other router (my main router) it works fine. When I boot into XP and connect to the problem router I can load pages fine. It's only when I'm on FC14 and connect to the problem router that I can't load pages even though I have an IP and can ping around.
How do I get rid of my wubi partition since Ubuntu doesn't work on a Vista laptop. Sorry, it was a gift for Christmas. I never realized Ubuntu was so defective.I am running Windows Vista 32 bit with 3 gigs of ram and one partition from the factory (HP).
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 have a VPS - and I was trying to install gd support for php on to it. Once I had done this I had a 500 Server Error. With the following errors in the log
[Sun Dec 12 07:34:29 2010] [error] [client 2.125.204.56] SoftException in Application.cpp:574: Could not execute script "/home/perfectp/public_html/phptest.php" [Sun Dec 12 07:34:29 2010] [error] [client 2.125.204.56] Caused by SystemException in API_Linux.cpp:444: execve() for program "/usr/bin/php" failed: No such file or directory
How to add parental control like { block web site access, restricting login access for particular time, restrict web access} for particular user accounts in Linux.
I recently upgraded my HP DV7 to 11.2. I did the install with wired network connection, my WiFi is always on as well. Install went fine, ran updates via YAST. I am running KNetworkManager, it loaded, configured eth0 and wlan0, prompted me for WEP keys and showed both connections working OK. I later found that when eth0 was disconnected, wlan0 was still connected but I could not reach internet sites. My router address was set as the gateway address and the DNS server address. Following several items on the forum, I tried 'dig' and 'route' commands.
I found that Code: HPDV7-Linux:/etc # dig [URL] ; <<>> DiG 9.6.1-P3 <<>> [URL] ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 28307 ;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0 ..... ;; Query time: 12 msec ;; SERVER: 192.168.10.1#53(192.168.10.1) ;; WHEN: Thu Mar 4 07:01:19 2010 ;; MSG SIZE rcvd: 69 returned a valid URL for that server - DNS seemed to me working properly via my router.
I found that Code: route returned: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.10.0 * 255.255.255.0 U 2 0 0 wlan0 loopback * 255.0.0.0 U 0 0 0 lo No default route showing.
I then opened the Network Manager connection editor, went to edit for the wireless connection and found under the IP_Address tab, Routes option box that both Code: Ignore automatically obtained routes and Use only for resources on this connection were enabled, I believe by the install process.
Unchecking these yielded Code: HPDV7-Linux:/etc # route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.10.0 * 255.255.255.0 U 2 0 0 wlan0 loopback * 255.0.0.0 U 0 0 0 lo default DD-WRT.capenet 0.0.0.0 UG 0 0 0 wlan0 and internet connectivity now working.
Could you pleaseme out.I have installed Virtual BOX on windows 7.Ubuntu i have installed on virtual box.Now i want to access internet from the Ubutu VM.
I am new to Linux, But, I installed it, all went well, but now, I can't access the Internet.So, I don't know what info you guys need, so just ask.Also, if it helps, I am using Ethernet (Well, I think it's Ethernet, it is a yellow cable with a rectangle end.
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.
I installed Apache2 and I added a second virtual host, now can i separate the 2 hosts and let them access 2 different internal test sites? For Example lets say"
User1 uses one IP User2 uses second IP
How can I separate it in Apache2 and in the /var/www ?
I'd like to ask a question on installing software.
I cannot install software using "yum" but I can with the GUI program "Add/Remove Software".
For example, I tried:
It will exhaust all the mirror sites without success.
All the error messages look like:
But I can install "screen.i686" easily from the "Add/Remove Software" GUI and it is very fast.
However, what's puzzling is that I could install some certain packages although I still see the same kind of error messages.
For example,
will work. But in general, "yum" is running very slow and is rejected at every mirror sites.
My settings: I just installed "Fedora 14" (Linux 2.6.35.11-83.fc14.i686) as a virtual machine (using VirtualBox) on a Windows XP (Professional, SP3) host on my laptop (CPU: Intel Core2 Duo), which accesses internet through a HTTP Proxy server since it is behind a corporate firewall.
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.
