Ubuntu Networking :: Connecting With AT&T 3G Card?
Jun 25, 2010
A group I'm working with recently got new netbooks with Ubuntu Netbook Edition 10.04 and some AT&T LaptopConnect (3G) cards. When I hook them into the usb port, the cards light begins blinking, but nothing shows up to indicate ubuntu has recognized the new card, nor am I able to connect to the internet. My searches for help have indicated no one else has had any difficulty with this and that the card usually pops up and installs some drivers automatically or something.
I'm not sure at the moment the model of the 3G card other than very new, but I can check on that in a bit. The netbooks are HP Mini 210s.

Recently I hibernated my computer, then when starting up again managed to boot into Windows instead. When I rebooted back into Ubuntu 10.04 my network card had stopped connecting to the internet.'s not a problem with my connection -- I'm posting this form Windows just fine. Using the network tools tool I can see that the card is inactive.I can use ifconfog to reactivate it, but it still won't connect.Attached is as many commands as I could find that provide information about the card

So I bought a used Dell Precision 390 Workstation and installed Ubuntu 9.04 on it. Everything seems to work fine, except for the built-in network card. Well, the graphics don't really work right, either, but I rather expected that, and I'll get to it later.
Anyway, when I boot Ubuntu and try to get on the internet, it says I'm not connected. When I open Network Tools, in the "Devices" tab, I get three Network device options: Loopback Interface, Ethernet Interface (eth0), and Unknown Interface (pan0). When I click on the ethernet device option, it shows me the hardware address of the interface, that it has multicast enabled, and that it is "Active", but I get no IP address.
Is there something really stupid that I'm missing? Do I need to do something special the first time I hook up an ethernet cable? I don't seem to remember having to do that on other Ubuntu boxes.

I have recently installed Ubuntu 10.04, and today the wireless connection has started to become spotty. The networks menu shows no wireless entries when they were there the day before. Again I have the Atheros AR5001 wireless card, my network is WPA2 and is 802.11g

I am trying to setup a blade server that has a QLOGIC 4062 mezzanine card to handle the iscsi traffic coming from an HP MSA 2312i SAN. I cannot seem to figure out how to get the HBA to talk to the SAN. Just to ensure the SAN was setup OK, I used the onboard netextreme NIC w/iSCSI to connect to the SAN with iscsiadm. This all works no problem. BUT, I bought the mezzanine cards to take this load of my NICs.
I know that the OS sees the two ports on the mezzanine card as dmesg shows them. This is my first time configuring a separate HBA on a blade system, so I'm kinda lost what to do with them. I have entries in the modprobe.conf file for eth2 and eth3 aliased to qla4xxx. What I am not sure about is the config for each eth2/3 device. If I ifconfig my device to the specific ip and subnet/netmask my SAN is on, I can get any response from the SAN.
Also I would have expected iscsiadm -m iface to pick up on the qlogic devices, but they don't show up in the ifaces directory. I tried to manually create an iface file for each, and it seems to be ok with that, but when I try to discover targets, I get communication errors. (I am compiling a file with all the outputs from various commands and errors, and will put them here once I have them).
What I don't understand is the process of setting up an HBA. I am quite able to setup iscsi over the regular NICs, been doing that for a while, but these HBAs have me stumped.
I also installed the qlogic qla4xxx driver and SANSurfer, but SANsurfer didn't see the HBAs. I think this was due to the age of the sansurfer software...other people have reported this as well.

I just installed Ubuntu 9.10 and its great. However when I connect to the internet at home it shows that the connection has been established but I still cant connect to the internet. My flatmates are all able to connect. However, I am able to connect from work both wirelessly and through an ethernet cable.

I seem to be have issues periodically connecting to wireless networks with WPA. It'll work one minute, and then I switch my macbook back on after a period and it refuses to connect again. It's happened on and off on three different networks now.
An example of /var/log/syslog:
Code:

I just did a fresh install of Squeeze with a KDE desktop on my computer. I use this computer to run an instrument in my lab. The instrument is connected to my computer through an ethernet card. Since my reinstall I cannot figure out how to get my computer and instrument communicating again. I'm guessing that I need to somehow tell my computer to connect to the device, but I don't know how. Here is my interface configuration:
[Code].....
I think my instrument is connected to eth2, which does not show any inet addr or Bcast ip, so I'm guessing that is a problem. How do I fix this?

I'm running Ubuntu 10.04 Server. I can't get my Wireless Card & Wired Card to work at the same time. My interfaces file is incorrect, when I comment out 1 of the interfaces the other works. I have attached my interfaces file.

I recently installed Xubuntu on my old P3 laptop (Compaq Armada E500 if anyone is familiar). The laptop is a bit old, so both wired and wireless networking is done via PCMCIA cards. I have 2 cards installed, one for each purpose. I can't find the dongle for the wired card right now, so I am trying to use the wireless card. I am able to find the network I want to connect to, and type in the password since the network is secured. It tries to connect but then pops up again asking for the password (I know it is correct). Is this card supported by linux/compatible? I tried finding drivers online but the sites that had drivers were down.

Just installed Fedora 14 from the Live CD i686 on my Dell Inspiron 1521. I can't connect to the SpeedTouch 585 on either wireless broadcom card or the wired Ethernet card.
I can connect to it from the same Laptop on the Vista which is on dual boot on the same laptop.
Further confusing is that I ran Fedora 14 and connected to another SpeedTouch today.
Already checked the Channel on the wireless nic and it's on the same one as the SpeedTouch.

I just want to use Internet Connection Sharing (ICS) to connect to the internet. I have done a massive amount of troubleshooting, but some of it seems to contradict itself, and the only two things that I know for sure are that it used to work, and that my Ethernet cable is not the problem. When I use Terminal utilities like ifup and dhclient it seems that it can not determine IP information, but when I try to put it in manually, the "Apply" button grays out right after I finish typing it in. When I try to connect normally, in KDE or GNOME, the icon acts like it's connecting, then instead of having the connected icon, I receive a notification that "the network has been disconnected", and it goes back to the disconnected icon.
Oh, and by the way, I know that I could probably find a workaround, but I have limited resources, and this used to work. The Linux is a Dell desktop with Fedora 12 and the Windows is a Windows 7 HP laptop.EDIT: I hope that I didn't mess something up, but I accidentally used system-network-config to try putting in the IP address there, and ended up changing it back to the original settings, but the computer is now calling it Auto Ethernet in the taskbar icon, although sudo iwconfig in the terminal still calls it eth0.

Forgive me if this has been answered, but searches have been un-fruitful. I recently built a 64 bit Ubuntu 10.10 pc. It is sitting right next to my Windows 7 Premium 64 bit machine. They can't see each other. I disabled Homegroup on my network. Now, when I try to access Ubuntu from Windows, I am prompted for a username and password. Both systems have the SAME UW and PW. It doesn't connect.When I go from Ubuntu to connect to Windows, I am prompted or Workgroup passwords.

I have often connected to my machine's remotely through ssh. Today I noticed that when I connect, the "last login" IP seems a little weird to me. I'm on my home network, so I connect directly with the IP of the computer within the router. But after the IP I get this XXX.XX.X.XXX.dedicated.neoviatelecom.com.br What is the neoviatelecom part? Is that normal? I don't remember ever seeing that there before. If I connect a couple of times from my win7 laptop (through cygwin) I get the correct IP address, but followed with the other part. If I connect with my other desktop (running Karmi 9.10) I get the same neoviatelecom thing as above.

I recently installed the latest version of Kubuntu in a dual boot system with Windows XP on a Dell laptop. The dell laptop has a broadcom wireless device, and I was able to set up the driver and get wireless working. Then I booted into windows XP to make a whole bunch of updates/driver installations, and when I booted back into Kubuntu it would not connect to the wireless network. I am pretty sure the device is still active, because it picks up on the wireless networks in the area. But KWallet does not open to ask for my password on booting. Something is not set right, but I can't tell what.

Situation: I can access Ubuntu from Windows XP but not XP from Ubuntu. When I try to access XP from Ubuntu I get message "Unable to mount location Failed to retrieve share list from server"
In System/Administration/Network Tools using Network device: Loopback Interface (lo) I can ping the IP address of the XP machine. Also, using Network device: Ethernet Interface (eth0) I can ping the XP by using its computer name.
In System/Preferences/Network Connections it shows under the Wired tab: Auto eth0 never used
Below are the settings in my smb.conf file.
## Browsing/Identification ###
workgroup = MSHOME
wins support = no
wins server = w.x.y.z
dns proxy = no

am using win7 trying to connect to a ubuntu box using vnc. I managed to get it working for me with the full gui viewable. Then one of my housemates played around with some display settings for the backround and all of a sudden vnd only comes up with a terminal.
I went into terminal and attempted to start gdm and got this output
root@ben-desktop:/home/ben# gdm start
** (gdm-binary:21376): WARNING **: Failed to acquire org.gnome.DisplayManager

I have 2 computers in my house, on my network. I want to connect to one computer to the other using SSH. On one I installed "OpenSSH-server". "OpenSSH-client" was already installed. I go to the other computer to try to connect to the "server" computer and I enter in the terminal:
Code:
ssh username@192.168.0.33
It never connects. The text input "bar" keeps blinking, it never connects and I get the "Connection timed out" message.
how I can connect to the "server" computer? What am I doing wrong? And if I edit my "/etc/ssh/sshd_config" file to listen to port "12345" how do I get the other machine to connect to that port?

I'm having a little trouble getting unison to work on Kubuntu and can't figure out why.I have two machines. One is a dinky little box that I'm using for version control and as a file server. It has an IP address of 192.168.1.5. My other machine is a laptop with an ip address assigned via DHCP. I can ssh from the laptop to the dinky box with no problems. However, in unison, I've set up a profile to sync /home/will with ssh://will@192.168.1.5/WillHomeSync. However, when I try to connect, it just hangs on the "Contacting Server..." window and does nothing. How do I even go about starting to troubleshoot this?

I have a Squid Proxy Server running on centos in my office. The proxy server is running OK and I have to apply the proxy settings in web browsers to access internet. I have also created different users to access internet. I have also created a VPN server in proxy server. It is also running very fine. People from outside and inside the office can connect to the VPN server. I have also opened all ports on proxy server.
Problem is, if any of my employee try to connect any other VPN server outside my office, it does not get connected. It shows some "ERROR 619". Whenever I try to connect it always show this error after verifying username and password.
I am not getting that where the problem is. Is there firewall problem in proxy server? OR anything else?

I have a problem which is connecting automatically to my spwireless. On my windows, my schools provide me the disc which contains several .cer files and a automated batch files to copy the .cer files to the root folders. I can choose to use the other network but in using that, i have to manually connect compared to using the spwireless. Anyway, my problem is that, how do i add the .cer files and to where so when i connect to the network it will look there for the cert. Because when i manually connect, only one cer can be chosen.

Sometimes I am unable to connect to my WEP network in ubuntu. No matter how many times I try, even restarting, it will not allow me to connect. However if I boot into XP, I can connect to the network. Then when I reboot again and then try in Ubuntu again, it will work.
Router is a Netgear MR814v2
