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 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 am using Ubuntu 10.04. My problem is that I am unable to access my internet using Ubuntu. My internet is running fine on Windows 7 installed on same system. I am a bit unfamiliar with Linux. I tried to configure my network settings but it didn't help. I have my system connected to my dsl router via LAN.
after installing some updates while on linux I am now unable to access the Internet when using vista. I m trying to solve this without success. Internet is still accessible from linux, and vista canl connect to the local network.
I have recently installed ubuntu 9.10. Earlier I had ubuntu 9.04. On that my internet was running perfectly well.After installation I created new connection as I had done for 9.04 version using "Network connections , Edit connections". However, after configuring connection(uname , password etc.) I wasn't able to access Internet.So I tried using "pppoeconf" utility. After using this now whenever I click on network connections applet on top panel , it shows in menu "device not managed".Can somebody point out what went wrong and what to do so as to be able to acess Internet in ubuntu?
When powering up with Linux, I get the message "THERE WAS AN ERROR CREATING THE CHILD PROCESS FOR THIS TERMINAL".I posted this on Newbies several months ago but received no replies. I hope this is the correct forum.I am using Windows XP Pro at the present.
On my Centos 5 box my internet won't work. I am unable to get update and I can't download any native programs. But I have Samba running and I am able to access all my files for my other computers.
To start off I do not have the ability to post in the Networking/Wireless thread. I attend DeVry university and in my school they recently rolled out "Bluesocket." Now that they have done this I am not able to access the internet utilizing my ubuntu laptop.I am able to connect to the network. When I open my web browser I am redirected to the "bluesocket" login page where I am able to successfully log in. The next step to accessing DeVry's internet service is to allow Bluesocket to do a scan using a Java applet. That scan is successful.
The results of the scan inform me that I am not being allowed to access the network resources because I don't have an antivirus or firewall program installed on my computer. I do not wish to have an antivirus or firewall program installed on my laptop to utilize DeVry's network resources. My question is what steps do I need to take to bypass/trick bluesocket?
I am using ubuntu (11.04) here, when i connect Bsnl broadband link(wired connection). Internet is connect automatically But unable to instal, upgrad and access Internet pages ..
I accidentally removed my network manager (gnome) from my system (via synaptic) and hence have not been able to have access to the internet to reinstall the packages. I have experimented with many commands (with help from others) in terminal with little success.
What I now did was downloaded a 'NetworkManager-0.8.0.999.tar.gz' file and a 'NetworkManager-0.8.1.tar.bz2' file (from a different comp) and have placed them onto my desktop. I have read the INSTALL instructions within and it is a tad complex for me as I am new to Linux. I understand I have to extract the files and compile them into a new folder (I think I would choose a file in the /home directory)- how would I go about doing this? Following this, I need to './configure' or 'make' or 'make install' the files
can't access internet. The up and down icon appears by the network connection (upper right hand corner). When I review connection properties, I see that the computer has a valid address, subnet, gatway, dns, etc... But it still can't connect to the internet. I can't ping external addresses either. But I can access internal addresses (local router).
Fedora 11 is completely unable to access the internet for some reason, and after some troubleshooting, I've determined the problem to my Motorola 2210 DSL modem. I know my connection is working fine, as it works perfectly in both Vista and 7. I've tried things such as grep 'Ethernet' /var/log/dmesg, filling in the information into the network settings manually, to no avail.
I've installed centos 5 on an old computer with success and it works great.I can access the web server hosted on the centos server from any computer on the wireless and wired local network. I can also use ssh (putty) and nx client from any computer on the local network (wired and wireless) to access the centos server.On the wireless router I've configured a port forwarding to the wireless network interface on the centos server. I can access the centos server from the outside (internet) through this port forwarding both through http and ssh or nx client.MY problem is that I can't access the centos server from the internet through the wired network interface. Any attempt to view a web page or login with ssh or the nx client will timeout.
Installing from Live USB: Installing from USB on my desktop (used this method for laptop install) goes without a hitch. EXCEPT, I notice there is no support for my wireless card chipset (Atheros 7413, used /bin/lspci to find). I download the drivers for Linux, but I need Make to build the drivers...ok. I download the Make files from my laptop, make coffee, slap the makefiles onto a flash drive and run the configure file on my desktop version of SUSE. Whoops, need a c compiler (odd that openSUSE did not come with gcc? bit confused on that). If you can't tell by now, I've been using linux for less than a month so I am what you would call a noob? After the lack of c compiler, I drove to my office to snag some DVDs to download the DVD iso image, hoping it would have some form of c compiler/make packaged, since the description does say the DVD has more software (can't find any prebuilt versions of either...?)
Installing from DVD: This was my next step. I wrote the iso image to a DVD and proceeded to boot from DVD. The installer fails at the system analysis, saying it cannot "create a repository". writing the iso to a second DVD produces the same result. Googling has not yielded a solution. tl;dr can't use openSUSE on my desktop because my wireless chipset is not suported by SUSE. I need Make to build the drivers, but I need a c compiler to compile Make, and I need the internet to get both for my machine.
we are trying to install this NIC Rosewill RC-400 Chipset RTL8169S-32 in Ubuntu 9.04 we downloaded the drivers from Rosewill website (For kernel 2.4.x and 2.6.x V 3.1) but when we follow the instruction in the readme file and do make clean modules and error comes out
So I went do realteak downloaded latest available drivers that seems to be were release yesterday did same command and same error So I made only make and it went fine did then make clean modules and went fine so made make install, depmod -a and modprobe r8169 verify int was up and getting correct ip from router but I'm not able to access the internet or ping any IP address

I have annoying problem. My setup is the following: debian Linux, 64 bits, VMWare workstation 7 host, with Windows XP running as guest. From Firefox, or Internet Explorer, I am unable to access few sites, for example nvidia.com, osdir. Basically get connection timed out, on the other hand ping works to those sites. Moreover, Slashdot loads very very slow and sometimes gets horrible text-only version.
everything works fine on Linux host
I suspect it has something to do with routing on Linux, I recall having similar problem long time ago, which was fixed by setting something in /proc.
I tried setting MTU and TCP window size on Windows lower, but did not help
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 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 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.
ok so i ran into a problem, im using web min to access my server, and im setting up postfix and, dovecot first problem is i want to be able to access my email account from a web page, with log in, so my question is how can i do that?
After upgrading to Ubuntu 10.04, I'm not able to make any connection to the internet with either my netbook through WiFi or my computer on wired LAN. I can, however, ping my Solaris machines and Macbook. How do I fix this?
I've been running a Samba server under RedHat 8 for five years without a hiccup. I want to cut over to a F10 box but cannot get shares accessible. smbclient attempts fail over NT password error. SELinux is disabled. Server is visible on the network. Users require no password access to shared data.
smb.conf follows:
# Samba config file created using SWAT # from UNKNOWN (>) # Date: 2009/06/12 14:15:15
Im having a serious issue with booting ubuntu 10.04, the issue being it wont boot up at all, after working so well for so long (i suspect some recent dodgy system updates are responsible) so I decided to just reinstall ubuntu from scratch again but wanted to retrieve some important files from my root device. So I am running the live desktop and I can see my previous filesystems under places but cannot mount or open my original root device where the files I want to recover are located, I receive this error msg:"Unable to mount 77 GB Filesystem.
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 have a dual boot in windows 7 and ubuntu. WiFi came with windows 7 but doesn't work at all in ubuntu.There are no drivers in my hardware drivers. I use one of those laptops that came with a built in atheros wireless adapter.
