Ubuntu Networking :: Can't Connect To Internet At Sites Requiring Sign-in?
Nov 16, 2010
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 have an odd Linux problem. Changed ISP recently -- Windows NT4 & W95 work fine. Linux has worked fine on previous ISPs, but on the newest ISP, I can connect successfully on Linux, but can only communicate w/maybe one out of 10 sites (Google, for ex.). Mostly I get "cannot connect to site". Some points:
-Linux is Slackware w/kernel build 2.4.26.
-No settings changed from Linux setup that worked fine on previous ISPs.
-/var/log/Log file says PPP connects via CHAP successfully & no problems..
-I don't see any similarity on the few sites I can connect to -- seems random.
-ISP is useless -- say they "don't support Linux".
-Using Firefox & Konqueror browsers.

I have an LG R-450 laptop with Ubuntu 10.04 installed in it. When I connect him to a network (either LAN or Wireless) it stays connected for a few minutes and then Just disconnects (without showing any sign of disconnection except no internet/skype/dropbox). Only way to renew connection is after startup. The network controller is SIS 191 Gigabit Ethernet adapter.

I've installed 10.10 yesterday on my old HP Pavillion ze2000 as dual boot with windowsXP and the wireless was working normally, I've updated everything it asked to update, rebooted a few times due to some of the updates. Today when I turned it on it was connecting normally to the router, though when I opened mozilla or tried to ping the router IP on the network tools neither have worked. Couldn't open any site on mozilla or ping any ip although it says I'm connected to my wireless router as it would normally. When I open into the XP my firefox there works just fine.

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.

Have just installed Ubuntu 9.10 in Vmware workstation 6.5.1 and unable to connect to external sites, or servers (using NAT). I can ping on host name and IP but can't resolve either host or IP in browser (Receive message the connection has timed out). I can't ping the host (Windows 7 Professional) IP from the guest and vice versa. I use a mobile wireless network card, and my Windows operating systems work successfully in vmware. Currently in my VMNet8 properties I just have Obtain IP address and DNS Automatically (same as host).

Over the last 3 or 4 days, I have been unable to load sites that serve their images, scripts and whathaveyou from Amazon's cloudfront domain.
[URL]
I have made no changes to any of my networking files, hosts{allow,deny}, or dns settings.
Connections don't provide any errors, just continually fail to load. Stopping the page load after a while reveals the raw HTML in some cases (quora and blekko).
Tested in Firefox, Chromium, Midori and Vimprobable.
I have booted into another distro and pages resolve immediately.
I have disabled IPV6 and my firewall - to no effect.

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

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 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 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 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.

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

192.168.10.0 * 255.255.255.0 U 2 0 0 wlan0

and internet connectivity now working.

I'm running squeeze/testing. Two or three days ago I became unable to get my mail from pop.gmx.net. A bit of investigation and I found that the error message I was getting was: "could not resolve pop.gmx.net: Name or service not known". Now the funny thing is that I can ping, traceroute, or nslookup the site successfully. Telnet, rlogin and ssh give the same: "could not resolve pop.gmx.net: Name or service not known" error message.
I have tried using the IP address instead of the pop.gmx.net and everything works fine. There is no issue with connecting to pop.gmail.com on the same port. Obviously there is some cache somewhere with a messed up pop.gmx.net. Any idea as to how I can track this down?
