Ubuntu :: Networking Broken With 10.04 / Solve This?
May 14, 2010
I installed Ubuntu on one of my machines a few days ago. It was an oldish CD containing 9.10. Eveything was puppies and rainbows. However, today I updated that machine to 10.04, and it no longer sees my network. Specifically, Windows doesn't see shares on it, and it doesn't see shares on Windows. Further, when trying to make a share (or rather update the one I had previously) I get the following:

Again, this is already the newest version.
And, being that I have no real idea what I'm doing, this is where my Googeling skills fail me. I want to reiterate, though, that before I updated today, networking was fine in both directions, i.e. from windows to ubuntu and from ubuntu to windows. How can I get networking to work again?

I am trying to find someone that can perhaps assist me with the following.
I have installed my notebook with Ubuntu 10.0.4 and need to setup various VPN connections to clients.
After setting up the microsoft VPN connections according to the normal procedures, I try to connect to one of the clients to test connectivity, but the connection fails.
This happens for all the MS vpn's so far.
I had a look at the daemon.log file and found the following message which I can't seem to find a solution to:
<WARN> connection_state_changed(): Could not process the request because no VPN connection was active.
Is there anyone that could perhpas assist me with this as I am not able to work without VPN.

I'm a total NOOB and I just finished a dual boot Ubunutu Studio 9.10 64bit/Windows 7 x64 install on a brand new i7 PC using a WD10EARS hard drive (with the new Advanced Format) and I gave myself top marks for getting by the mammoth amount of obstacles to accomplish what I have so far.
Item of note: you can NOT do a complete install with Ubuntu Studio 9.10 using a wireless device. The installer ONLY recognizes motherboard ethernet ports. No worries, I moved it to the office and the LAN line and got a complete install. I am using this in my living room though as a Media PC with MythTV and the distance requires me to use WIRELESS.
After a successful install, I was unable to get my brand new, out of box Netgear WG111v3 to establish a successful connection and I need your help. Pardon the length of this post, I will try to organize it as best as I can but I have done a LOT of troubleshooting before posting here. Here's what I did so far:
1. Tested Wireless in Win7 on same PC. Works GREAT! Rebooted, went into Ubuntu Studio 9.10 and got no joy.
2. This page says the WG111v3 works out of box with Karmic and I can state with 100% certainty it does NOT.
3. Went to this page (which is THE best how to out there) and followed instructions. I discovered a bug in wpa_passphrase immediately. I use a very complex passphrase using !#$&@ characters in the mix. wpa_passphrase dies with various errors when it sees these characters because it thinks they're command items rather than part of the text in my key. Try it yourself. Create any long text string with those characters and input it to wpa_passphrase. It dies. Works fine with regular letters/numbers. I had to use this page to get the HEX value for my passphrase so I could complete my interfaces file. On a hunch, I changed my passphrase on the router to be a simple 10 letter word all in lower case. wpa_passphrase changed that to HEX fine, updated interfaces file, rebooted router and PC and got nothing. So it's NOT the passphrase.
4. Went to this page, which again states it works out of box but doesn't and tried all the help there. NO JOY.
5. Tried here too. The help there is good when combined with #2 above but still nothing.
6. Went to unsupported versions of Ubuntu to try some old school tricks. Got nothing.
7. Found this site and it has EXACTLY my problem! I always end up with "No working leases in persistent database - sleeping." when it tries to get an IP address from the router. As you can see, that user found no fix either.
8. I turned off ALL security on the router and left it wide open, updated my interfaces file appropriately, rebooted everything and it still couldn't connect?

I'm new to ubuntu and using 9.10. I have installed a dlink wua 2340 wireless adaptor and it is working properly. But after waking up computer by standby mode, wireless connection breaks and the wireless device is not mounted. Therefore I always have to shut down the computer and restart again to establish wireless connection.

I have a Dell Inspiron 1525. I am unable to connect to wireless networks. I have a fresh installation of Ubuntu 8.04. I have installed Ndiswrapper (ndiswrapper-utils_1.8-0ubuntu2_i386.deb) and the GUI for ndiswrapper. The ndiwrapper GUI reports that the hardware was not found. Yet I am able to connect to the wlan using Windows.

I recently did a clean install of Ubuntu 10.04 and tried using a DLink DWL-G122 dongle for a wireless connection.
It seems to connect to the wireless router, but I cannot seem to access any websites using the wireless connection. Ethernet connections to the computer work perfectly, but ethernet isn't ideal.
The results of the lsusb command is code...

I'm unable to get my Ubuntu 10.04LTS to see my Mac 10.6.4 machine.
I've got Samba and AFP enabled under the Mac file sharing preferences.
Attempt1: From Ubuntu, I can see my Mac under Network>Places, but I'm unable to mount the location.
Attempt2: In Ubuntu, I went to Places>Connect to Server and entered the following:
Service: Windows Share
Server: [name of my mac]
Share: [name of my shared folder]
Folder:
User Name: [username]
Domain Name: WORKGROUP
With this entered, I was able to get as far as being prompted for my password, but was still unable to connect.
Attempt3: I followed the same steps above, but left Domain Name blank. Still nothing.
Are there any docs out there for the correct steps? I can only find posts on getting Mac to see Ubuntu, but not the other way around.

I tried installing the mac80211 framework on ubuntu 10.10 but after i install it and restart my system , none of my network connections work.
i found a solution to that problem which is a very weird solution. because none of the network connections are working . i try to activate the wireless driver from the System->Administration->Additional Drivers. But it fails , but after it fails my wired network connection comes back online. and then i have acccess to the internet . After that i activate the wireless driver again and it works.
This is obviously the worst possible solution ever. So what i don't understand is why the mac80211 framework is causing these problems. after applying my "solution" i thought of checking the modules installed on my system using lsmod and i see mac80211 there. i don't understand why it is still there after i executed the "sudo make uninstall" command . code...

I configured an internal fake ip 192.168.1.11 on a virtual interface of my server.
I'm running one of my postfix instances on this ip.
The problem is that postfix can't talk to external hosts on the internet when running from this internal ip 192.168.1.11
I get an error in the mail log
Feb 21 22:43:00 localhost postfix-R1/smtp[11372]: connect to 7zips.com[109.169.46.199]:25: Connection timed out
It works fine when I run postfix on real ips, but I need it to work from the internal.
I thought it should just work.
Am I missing anything?

I use Ubuntu 9.04 and try to get a Sweex LW053 USB wireless card (Ralink RT73/RT2500 chipset) to work. According to the Wiki list in the sticky thread, this one should work "out of the box" since 8.04.
lsusb delivers
Bus 002 Device 002: ID 148f:2573 Ralink Technology Corp. RT2501USB Wireless Adapter
and there is also some wlan0 entry that doesn't look too dodgy when typing ifconfig.
From this I get that my laptop recognizes the card.
I also typed in some numbers such as SSID and DNS server address in Preferences>Network Connections where asked (although the information that I had wasn't 100% what was asked for so I tried to guess what needs to be filled in which fields).
However, I don't get an internet connection (Firefox can't find server...)
What else do I have to (or can I) do?

I'm new to linux. I've just installed Ubuntu 11.04. It has all been going ok, but the wireless just stopped working all of a sudden. The indicator light turned off and when I tried to turn it back on (Fn+F2) nothing happens. Sometimes, when I restart the computer, the wireless might work; but if the signal is lost the LED on my laptop turns off and I cannot reconnect. Also, in these strange cases that the wireless works when I restart I can manually turn it off (Fn+F2), but nothing happens when I try to switch it back on.
In the menu on the upper right corner I see 'Enable Networking' is checked, but 'Enable Wireless' cannot be modified.
I have a Dell Inspiron 6400 and the wireless device is an Intel Pro/Wireless 3945ABG.
I have tried to follow some of the threads on this forum on similar cases, but the ones that were comprehensible to me did not work (or I actually might not have understood them either). code...

I have been trying to set up openVPN on a Virtual Machine running Ubuntu 10.04 with the eventual intention of having a closed VPN in the workspace I'm at, and a bridged internet connection out through the server.My initial process/instinct was to go through Webmin. After a fair bit of tooling around making eys/certificates, I was able to get a response (and that's all it was, really) from my windows machine accessing the VPN server. However, in my attempt to bridge the network, I have lost all internet/networking capabilities from the server.Fortunately I am able to access the server directly from the hardware underneath (i.e. I don't need to SSH in or anything), and so I've been attempting to restore the server's networking back to default. I have returned the /etc/network/interfaces file to it's original state (just the loop, and an eth0 on dhcp) and restarted the networking. A check with ifconfig returns what seems to be a working eth0, and the loop (noting else) however I am unable to ping any outside server. When I do, I am given the message:From XXX.XXX.XXX.XXX icmp_seq=1 Destination Host Unreachable(where of course XXX is my IP address).nother VM on the server is able to access the internet just fine, so it's not the overall server hardware...I guess at this point I'm just trying to take steps back,

I have a jaunty installation which is working fine, and I'm gradually getting a dual boot of karmic (desktop amd64) up to speed to take over from it. I've got a fairly standard ADSL modem/switch/router connected by wires to the machine as eth0.I setup local static IP etc. during installation (no DHCP at all) and it worked fine for quite a while. Then, after an upgrade one day, DNS broke on reboot.After booting now, /etc/resolv.conf is essentially empty (just comments) but the networking service is up. I can ping places out on the web.If I "/etc/init.d/networking restart" then /etc/resolv.conf gets the correct "nameserver" and "search" lines added to it and everything is fine... until next boot.I never really worked out exactly how Ubuntu controls its networking config, and I'm further confused by the changes to the booting setup in Karmic

I have a thinkpad using the iwl3945 driver (Intel(R) PRO/Wireless 3945ABG/BG Network Connection driver for Linux, 1.2.26ks).
This worked flawless until I upgraded to 10.04. Now after a while my connection drops. Syslog is appended.
May 10 20:16:04 gimli NetworkManager: <info> Activation (wlan0) starting connection 'Auto my-network'
May 10 20:16:04 gimli NetworkManager: <info> (wlan0): device state change: 3 -> 4 (reason 0)

internet access is no longer working on my computer, ie wget, ping, apt-get update all return unkown host (url or whatever).
However the system monitor (Network History) shows that the system is sending and receiving packets. And what I think is network manager applet shows active network signals for both wireless and ethernet.
I know my laptop has not acquired hardware faults. Since I am posting this message and accessing the internet through the same computer with a Ubuntu live USB start up disk.
I searched through the forums for related posts and tried suggestions. Forinstance
the /etc/resolv.conf
file is the same for both live usb system and hard drive system, so it can not be that.
# Generated by NetworkManager
nameserver 79.138.0.180
nameserver 85.8.31.209
the /etc/network
interfaces file looks like:
code....
I tried the system test (System->Administration->System Test), with only Network tests selected). The results of system test were so extensive I searched for the word internet and extracted lines for internet. Interestingly it says both the network_test and the internet_test are _passed_.
But the internet does not work in either in web browsers or with BASH commands.
And also:
erlang-inets Erlang/OTP Internet clients and servers
python-twisted-bin Event-based framework for internet applications
python-twisted-core Event-based framework for internet applications
network_test pass
internet_test pass

I have just upgraded 2 machines to ubuntu 11.04. One was an upgrade, the other a new install. On both machines, I cannot ssh to any machines running Ubuntu 10.04.2 I can ssh to machines running 10.04.1, 10.10, etc. and all those machines can connect to the 10.04.2 machines. I get: Read from socket failed: Connection reset by peer To workaround the problem, I have copied the /usr/bin/ssh on a 10.10 machine to the 11.04 machines.

I recently upgraded Ubuntu 9.10 to 10.04 and my wireless stopped working. It can detect that there are networks around, what their signal strength is, and then try to connect to one, but it just keeps connecting. After around 5 minutes, this stops and nm-applet says no network connection.
After I try to connect, dmesg is spammed with hundreds of the same message. I can not post these here, as I am writing from a different computer and I have no internet access from my main computer.Also, there is nothing in interfaces.conf other than lo. For some reason, my card is referred to as both wlan0 and wmaster0, with this changing depending upon where I look.Most interesting of all is that, even after I reinstalled 9.10, wireless is still broken, even though it wasn't before. It also used to work under liveCD.

I recently installed ndiswrapper and decided to remove it after some kernel panics. The problem is that it overwrote something because I have the compat-wireless-backport driver installed but 'wlan0' doesn't show up anymore. I can see my wireless card when I type 'lsusb'. Any ideas on how to fix?

I have a number of CentOS 5.4 machines that use kerberos to authenticate. This works fine. However, after upgrading one of them to CentOS 5.5 it is no longer possible to log in.
In 5.4, I get this in the log:
> called to authenticate 'hans', realm 'MYREALM'
> authenticating 'hans@MYREALM'
> not using an entered password for 'hans', allowing libkrb5 to prompt for more
> authenticating 'hans@MYREALM' to 'krbtgt/MYREALM@MYREALM'
[code]....
Note the absence of the line where libkrb5 asks for a password. Running "kinit hans" on the machine (as root, who can log in) works as it should, so I don't think anything is wrong with kerberos as such (as I did yesterday, in [URL]. Clients still running 5.4 have no problems, so the problem was introduced in 5.5.

I'm not sure if I have two seperate issues or one inter-related issue. The Network Manager applet wasn't appearing in the tray, found out it wasn't installed. Installed, still didn't appear. Tried installing WiCd, WiCd did appear but couldn't find any networks. I had installed restricted drivers previous, decided it was worth another look. Found that Broadcom STA Wireless Driver wasn't installed. Tried to install, it said it couldn't and said I should review the var/log/jockey which is....excessively long.

I just upgraded the kernel on my Ubuntu laptop from 2.6.32-24-generic to 2.6.32-25-generic (using the update manager under gnome). After the update, the wireless network controller shows up as UNCLAIMED when I do lshw -C network.When I try to install the driver with the commands sudo modprobe lib80211 sudo insmod wl.ko
i get this error message: insmod: error inserting 'wl.ko': -1 Invalid module format
I have compiled the driver using the 2.6.32-24 kernel. Do I have to re-compile with the new kernel?I'm a unix user, but not a kernel hacker, so I'm wondering if I will run into problems every time I get a kernel update? Or is this problem an exception?

Been helping a user who recently upgraded to 11.04 as his networking stopped after the upgrade. One thing I noticed was that he could not get ping to work.Then checked my 11.04 machine and it also fails to ping using Network Tools. I know the network is OK as I am using my Ubuntu machine to write this. Ping from the command line is fine so it is only the Network Tools ping test that appears to be broken.
Asked another Ubuntu 11 user to check his machine and he also cannot get ping to work even though his machine appears to be fine. Again this is only using the GUI tool.I know it is not hardware as I can dual boot and in XP everything is fine and I can ping all my systems. Also I am sharing a folder from my Ubuntu and my Mac shares the folder just fine. The Mac can also ping everything except the Ubuntu box. Command line ping works so it is not a basic network problem.So as far as I can tell the Network Tools ping test is not working. Has anyone else seen this or can confirm that it is broke. How do I report this or get it fixed?

for over at week i have been trying to get my wireless card to work now. If i open Additional drivers, the non proprietary driver seems to be working and active. If i deactivate that and use the STA driver instead, it says active, but currently not in use. When i use the non proprietary driver, i can check mark on 'activate wireless', but nothing happens. When i use the STA driver there are no wireless options. I'm not sure if its important, but when i do "sudo lshw -C network" when the STA driver is active but not in use, the network status changes from 'disabled' to 'unclaimed'. When i came here, i tried to install "firmware-b43-lpphy-installer" as the sticky said i should, but the installation fails. It says my card is not supported: "Not supported card here (PCI id 14e4:4727)!"
