Ubuntu Networking :: VPN Not Working After Upgrade To 10.04?
Aug 13, 2010
I've just upgraded from 9.10 to 10.04 and I cannot connect to my university's VPN now. The error says "Connection attempt timed out". Hopefully the following log might be useful in solving this.
I've searched but cannot find anything useful. I've re-entered the details to make sure they're correct, reinstalled the pptp package.
Code:
chris@chris-desktop:~$ tail -f /var/log/syslog
Aug 13 12:52:21 chris-desktop pppd[3321]: Child process /usr/sbin/pptp student-vpn.bris.ac.uk --nolaunchpppd --logstring nm-pptp-service-3279 (pid 3322) terminated with signal 15

This should be easy for the Ubuntu Gods to sort out:
I have a Sabrent USB 802.11N adapter. (I am using 64-bit Ubuntu in all below)
I plug it into a 9.04 box and it works fine. Plug it into a 9.10 box. Network manager sees it and can attach to the network, but has 0% signal strength, no internet.
Rebuild the 9.04 box with a fresh install to 9.10. 0% signal, no internet. Try 10.04 Alpha 2, 0% signal strength, no internet.
Rebuild same box down to 9.04. Works perfectly. 100% signal strength. I do all updates and then the upgrade to 9.10 using the USB. Everything works fine until the reboot. Then, USB connects, but 0% signal strength, no internet. Oh! ifconfig says the wlan0 interface is up, but it has a random ip address.
I don't mind using 9.04 because for the forseeable future, the box is just going to count aliens for Seti, but my wife wants it off the counter and I would like to upgrade someday.
I'm currently running Ubuntu 9.10.After I updated to 9.10, my wireless connection stoppped working. I can access the network but I get no response or what so ever in my browser.Downloading language support or any software doesn't work either.Haven't changed anything to my settings and checked the router. Router works just fine.
I recently upgraded to 10.04 and now my wired network no longer works. I am unsure if it worked at all since the upgrade as that computer is rarely used, but it was definitely working prior to the upgrade. It is some sort of Realtec card, I believe. Does anyone have any suggestions? I'm running 32 bit 10.04 on a 2 GHz P4.
I upgraded to Ubuntu 10.4 on my Dell Inspiron 6400 yesterday (32-bit). Everything was running great, but when I turned it on today my wireless adapter is no longer working and the hardware switch doesn't do anything. It's working in Windows fine so it can't be the hardware.Here is some information:
Restarting the network with 'sudo /etc/init.d/networking restart' didn't work.I've tried Ubuntu several times before but usually there is one small issue which makes me go back to Windows. I love 10.4 so I hope I can get this working so I can stay on Ubuntu!
I'm having the same Harker2010 's problem.Running 10.04 LTS on a Dell latitude D-820, and switching between lan and wifi worked OK until last upgrade.Harker2010's screenshots are also valid for my problem. I've tried everything I see on this post but the problem still there.
after upgrading to 11.04, I can't use the fn-f2 combination anymore to activate the wifi card. I'm using a Dell latitude laptop. Wifi is functioning normally when it's on and I can even turn it off with the hotkeys. When I try to turn it back on, the light goes on for a second and than dims again. I than have to reboot into Windows to get it back on, which is kind of annoying.
After upgrading to 11.04 about six weeks ago I've had no sufficient solution to my inability to connect to wireless. Here is a summary of the problem:
After the upgrade, nm is running, and lspci detects my wireless controller (Atheros AR2413 802.11b/g), but nm can only sporadically detect/connect to wireless networks. Essentially what happens is that upon startup, I have to wait (sometimes 5 minutes, sometimes hours) for the computer to "decide" that it wants to detect the networks, at which point I can connect. After this it is fine; it doesn't disconnect after this point, but more often than not it takes so long to start working that I might as well not use the computer.
I've tried "Connect to Hidden Wireless Network", to no avail. I should mention that I also run under the Gnome Classic UI, because Unity is one of the worst UI changes I've ever seen in a version. I've read that Unity causes some problems with NM, but I have no corroborating evidence of this, and the problem persists even without using the Unity UI.
Someone recommended using an older kernel, but the file "menu.lst" doesn't even exist in the /boot/grub folder, so I have no idea how I would do that.
I just did a dist upgrade on two computers. One of them was fine with the network manager, but the other, netbook, now refuses to start the service. If I do service start network-manager I'll get a message saying a process started, but it must be immediately dying since I can't find the pid or any network manager processes at all. I looked at daemon.log and noticed it was complaining about nm-system-settings.cfg not being there. One question I have is how is this not getting generated? It's not in the deb so somehow it must be generated. I put a fake file in there and even put some data from a pastebin I found online that looked promising, and the message in daemon.log went away but the pids were still dropping off.
I have many problems with nm-applet, but I don't want to go into it so much now that the service can't start. The problem I do see popping up is something like: ** (nm-applet:2622): WARNING **: <WARN> applet_dbus_manager_start_service(): Could not acquire the NetworkManagerUserSettings service. Message: 'Connection ":1.24" is not allowed to own the service "org.freedesktop.NetworkManagerUserSettings" due to security policies in the configuration file' (had to pull message from online, don't remember the exact message) I've tried installing and reinstalling, doing a purge uninstall. Next thing I was going to try is an aptitude uninstall of all of the dependencies in case something got weird in the upgrade.
I just upgraded to 10.04, as of this upgrade, samba has quit working.
From Windows I can ping the linux box (192.168.1.110) If from Windows I key in ->Start->Run->\192.168.1.110 I connect to my linux box.
If I try to access the linux box through the name, (\tardis) I get network path not found.
Everything worked fine before the upgrade, now I cannot see my linux box via its network name. I have a WD TV Live on my network and I must be able to see the linux box via its network name or I cannot connect to it.
iptables shows no rules
smbtree returns SONCOM \WINDOZE \WDTVLIVE WDTV LIVE Server requested LANMAN password (share-level security) but 'client lanman auth' is disabled failed tcon_X with NT_STATUS_ACCESS_DENIED
Like many others it seems, my wireless has stopped working since a recent upgrade The answer does not lie in analysis of logs, settings etc. but surely with those who did it - they should provide a fix. I cannot believe everyone expects each individual users to go into their own analysis of why this is no longer working as it is clearly widespread. I have been using Ubuntu for 18 months without this problem on the same dual-boot laptop, and it still works on Windows as before, only Ubuntu 10.4 has recently stopped my network card from working.
I need to know when this will be fixed. I have been embarrassed by promoting Ubuntu to many colleagues who now also cannot work at home on their wireless networks. Seriously disillusioned I may start looking for a more stable alternative to Windows.
i have a dell 1501 that has been upgraded from 10.10 to 11.04. everything was working okay. and then the user ran an upgrade recently. subsequently the wifi has mysteriously stopped working. it connects okay if one plugs it directly into the router but the wifi seems to have just stopped working.my mini 9 connects fine to the netgear wifi router using wireless.when i run the system tests for networking i get the errors..."root could not find def gateway info /proc""root could not find default gateway by running route"here is the output from some diagnostic commands.NOTE:this is similar to a post titled "wi-fi dead?" but the output is not quite the same...
lauren@lauren-Inspiron-1501:~$ iwconfig lo no wireless extensions. eth0 no wireless extensions.
I'm running Fedora 15 KDE on a Sony Vaio VPCS13V9E. No problems in connecting to the wlan. Today I upgraded the system. There was an upgrade for Network Manager. After the upgrade the system is not able to connect to the modem - router (Linksys WAG320N) any more. Network manager keeps on crashing and sends messages like "network disabled" or "connection failed". Kde demon is reporting errors too. I guess the new version of Network Manager is bugged, because before the upgrade it did work well ... (unbelievable!).
On a fully updated Ubuntu 9.04 system, I had successfully configured wvdial to connect using a USB modem ("Update" brand) with an ID of 067b:0611 (uses the pl2303 driver module). In considering an upgrade to Ubuntu 9.10, I tried a LiveCD and was unable to connect using wvdial. However, because I had made the CD a couple months before, I went ahead with the upgrade (via the internet; not a fresh install) in the hopes that it would end up working or I would be able to find a solution for it.
The Problem: The upgrade was a success as far as I could tell, but when I tried to connect to the internet with wvdial, I was not able to. I checked the wvdial.conf settings to make sure they were the same as before, added some new ones I thought it might need, unplugged the modem and replugged it, restarted my system, etc., but all to no avail. Whenever I would try to run wvdial to connect, I would get the following output:
Code:
--> WvDial: Internet dialer version 1.60 --> Cannot get information for serial port. --> Initializing modem. --> Sending: ATZ
[code]....
This was different than the output I used to get with wvdial, but when I went over to my browser (Firefox) the internet worked fine. I'm assuming my email client and other things will work okay as well, but have not tested them as of yet.
A final touch I did to make connecting a bit less 'painful' was to right-click on the panel (at the top of the default Ubuntu screen), and click on 'Add to Panel'. Then I selected 'Custom Application Launcher', chose 'Application in Terminal' for 'Type', gave the launcher a name, pasted in that 'horrifically' long command line above, gave a brief description in the 'comment' box, then pressed 'OK'. Voila! I now have a launcher on my panel that with a single-click will bring up a terminal screen where I enter my sudo password and it connects. Then when I want to disconnect I just go back to that terminal, press Ctrl+C, which promptly disconnects me and causes the terminal to vanish into thin air.
Now, I don't know enough about this stuff to know why this command worked and wvdial didn't, but if you know, feel free to post a reply. Or if you'd like to see what settings I had for wvdial that worked in 9.04 but not in 9.10, let me know. Or if you think it's worth checking to see if this should be posted as a bug in either wvdial or Ubuntu, you can mention that as well.
Well I guess the topic says it all. I've recently upgraded to Maverick from Lucid all went smoothly until i restarted and realized that the remote desktop server included stopped functioning all of a sudden. tried other vnc servers with no luck.
I just remotely updated my uncle's Ubuntu 10.10 desktop to 11.04. My uncle has no computer skills, so it is very important that I troubleshoot his problems using VNC. After completing the 11.04 upgrade, I was not able to connect to him via VNC. After some fiddling around I was able to connect by turning off the confirmation option in the Security section. We are now using the password security option. The problem is that my uncle does not have any security against my peering eyes.
I tried reinstalling Vinagre, but that didn't help. Is it possible to get the confirmation option working again somehow?
I have a Broadcom wireless card in my hp dv6500z laptop, I had it all working properly in FC9 thanks to bbfuller and his post on the subject. After I upgraded to FC11 I have been unable to get it to connect.
I can see my neighbor's sites and suppose I could see my own if the SSID was allowed to broadcast but I keep that turned off. I put in all of the setting, including the network security key, but it won't connect, then when I go back and look again, the security key is not even close to what I put in; it gets changed to a huge string of characters.
I redownloaded broadcom-wl-4.150.10.5.tar.bz2.tar and followed the instruction on the post once again but no luck, which, after I thought about it, was a waste of time because if I can see other's wireless, then the card must be working. I have tried using Network Manager and not using Network Manager and still no luck...
I am running Fedora 14. I've had an ASUS wireless adapter working for a few months now, with no problems. Today, I installed updates, one of which required a computer reboot (not just logging out and back in). I rebooted the computer, and when it came back up, the wireless adapter did not work.The adapter is visible after lsusb, but there is no wireless showing after iwconfig. What happened? How do I fix it?
After upgrading from karmic to lucid yesterday made my RTL 8111 -network card die. It's integrated on Intel D510mo mini-itx board.
dmesg:
Code:
After some googling I found out a lot of forumposts about the same problem from year 2007, but the troubles seem to disappear on the newer versions and seem to be back now? With those posts I managed to get the link up by using ethtool by setting autoneg off and setting speed to be 10mbps and half duplex. Any other speed/duplex combination fails.
One suggestion I found was to install r8168-driver from Realtek instead of the r8169. It didn't help, result was very much the same.
I booted to 9.10 live-cd and there the network worked as intended (100Mbps, I dont have a gigabit switch)
I really wouldn't like to fall back to 9.10, but my file server is not very usable with 10mbps.
1. D-Link DWA-643 Xtreme N Express Card Adapter The onboard wireless for my HP tx1000z stopped working a long time ago. This wireless adapter is in my express card slot.
My Intel Corporation WiFi Link 1000 Series wireless card stopped working yesterday after I did an update via Update Manager.After the upgrade, wireless is disabled and the option to enable it in Network Manager is grayed out. I thought that it might be the new kernel, but changing back to the old kernel I still have the problem.
I have 7.04 edubuntu from our government as I am a teacher and I got laptop. So I am asking can I upgrade to 7.10 or some newer version?? If not at all, why is not working the repo sites, I mean I don't get why is not working the upgrade manager.
I try to run sudo apt-get update. It doesn't seem to work. I get a lot of 404 errors, and files that can't be found. This is what came from the terminal:
After apt-get upgrade on Karmic, I'm having trouble with name resolution. Main problem now is that the 'order hosts, bind' directive in /etc/host.conf is not respected. A side symptom is this error code...
I'm not entirely sure this is the proper place for it, but aee doesn't work anymore after upgrading to 10.10. In both gnome terminal & konsole it says "sorry, unable to use this terminal type for screen editing" and exits. It does this remotely even through ssh sessions.
I know aee isn't exactly a new program or anything but what gives? It's a terminal window, how could a console based text editor go wrong.
I upgraded from 10.10 to 11.04 and empathy has stopped working for me. Gives following error message from terminal
Code:
empathy: /usr/local/lib/libtelepathy-glib.so.0: version `TELEPATHY_GLIB_0.13.11' not found (required by empathy) Empathy version is 2.34.0-0ubuntu3 and libtelepathy-glib0 version is 0.14.3-1ubuntu1
I had Ubuntu 10.10 installed on my main computer. Having been trying out 11.04 for quite awhile, I decided to install it on my main computer after it was officially released. I did this via an upgrade. Problem is now that I'm not getting any options for unity 3D. On the log on screen i have an option for unity 2D and unity, however both are unity 2D. My computer has a built in graphics card, nothing amazing, but i have happily used compiz effects on it previous to this.
My graphics card is up to it so why is the unity session falling back to unity 2D? Another problem that I'm having is that i cannot get the launcher in unity 2D to move out of the way. I even installed a programme called 2D Desktop Setting to try to fix this problem but selecting the various options to show, hide, autohide, etc have no effect at all and it's really frustrating having the launcher covering up the left side of my screen.
