[Bug 396387] [NEW] Unable to resolve VPN names AND connect to the Internet
Public bug reported: Binary package hint: network-manager-vpnc 1) I am running Ubuntu Jaunty 9.04 (upgraded from Ubuntu Intrepid 8.10) 2) Version for network-manager-vpnc: 0.7.1~rc4.20090316+bzr21-0ubuntu2 3) When I use VPN on my home PC to connect to my work LAN, I expected to be able to resolve my work PC's name and surf the Internet normally. This was the existing behavior in Intrepid 8.10. 4) When I connect to my work LAN via VPN, my home PC could not simultaneously surf the Internet. I could resolve my work PC's name and I could ping my work PC's IP address. I found a solution where I should edit my VPN connection -> IPv4 Settings tab -> Routes -> check "Use this connection only for resources on its network". When I did so, I was able to surf the Internet, but I could NOT resolve my work PC's name. Pinging my work PC's IP address was still OK. Summary: "Use this connection only for resources on its network" is unchecked: - nslookup my_work_pc (this took a few moments, but it correctly returned my work pc's IP) - ping my.work.pc.IP (this worked correctly) - ping 74.125.127.99 (this is google's IP address. this FAILED) "Use this connection only for resources on its network" is checked: - nslookup my_work_pc (this FAILED. ** server can't find my_work_pc) - ping my.work.pc.IP (this worked correctly) - ping 74.125.127.99 (this worked correctly) Other info: - My vpn type is "Cisco Compatible VPN (vpnc)" ** Affects: network-manager-vpnc (Ubuntu) Importance: Undecided Status: New ** Tags: vpn -- Unable to resolve VPN names AND connect to the Internet https://bugs.launchpad.net/bugs/396387 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 368602] Re: Display issues and Slowness with Xubuntu 9.04
I can confirm this bug. My PC is a Celeron 366, integrated ATI 3D Rage Pro AGP 1X. I upgraded from xubuntu 8.10 to 9.04 using the Update Manager. My filesystem is ext3. - The time between entering my user name/password to displaying the desktop takes a noticeably long time now, about 50 seconds for me. This occurs on every login, not just the first login after boot. - The screen resolution defaults back to the highest resolution and highest refresh rate, in my case 1152x864, 75 Mhz. This is the highest setting as displayed by the command "xrandr". This occurs on every login, not just the first login after boot. - Additional "slowness" issue: The first time you click the "log out button", a gray half-transparent window covers the whole screen, which is OK. But it takes about 4 seconds for the logout dialog to be shown. If you cancel the logout dialog and click the log out button again, the logout dialog is shown immediately. I think this was faster in 8.10, because I never took notice of a logout delay until I upgraded. This occurs on every login, not just the first login after boot. Please let me know if I can help in any way.

[Bug 396387] Re: Unable to resolve VPN names AND connect to the Internet
Since the results were long, I have attached the results in a .txt file. The only modification I made to the results was to edit out my work company's name and used "my.work-domain.com". Otherwise, the results were copied directly from the console output to the .txt file. In analyzing the results, the output of /etc/resolv.conf was identical. The output of netstat -rn was identical, EXCEPT for the last line: "Use this connection only for resources on its network" is unchecked: Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 tun0 "Use this connection only for resources on its network" is checked: Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 0.0.0.0 192.168.1.1 0.0.0.0 UG0 0 0 eth1 Other notes: - eth1 is my gigabit network card.

[Bug 396387] Re: Unable to resolve VPN names AND connect to the Internet
Since using "my.work-domain.com" would be vague and confusing, I have decided not to hide the actual domain. That way, you will be able to run tests of your own. The original domain name is svl.access- company.com. I will continue to hide my work PC name and IP address. > my.work-domain.com is resolvable both by 68.94.156.1 and 68.94.157.1 It turns out that svl.access-company.com is NOT resolvable by these two. I can prove this by trying to resolve svl.access-company.com when disconnected from VPN. ** server can't find svl.access-company.com: NXDOMAIN Hmm... if the sbcglobal.net DNS servers failed to resolve svl.access- company.com, I wonder why Ubuntu didn't try my work DNS next. Had Ubuntu tried my work DNS server next, it would have resolved correctly. > and enter your DNS server's IP address and domain to search through I presume you mean for me to enter my work DNS server's IP address and my work domain. I have attached the results of this test. The results are the same: I still cannot resolve my work PC by name. After understanding that this is a DNS name resolution problem, I decided to conduct my own test. I connected to my work VPN, then manually edited /etc/resolv.conf and moved my work DNS ABOVE the sbcglobal.net DNS servers. The results were that everything worked exactly as they did in Ubuntu 8.10. I could connect to my work PC and I could surf the Internet. So hope that helps. The results are also in the same attached file. ** Attachment added: "BUG396387 addresses only.txt" http://launchpadlibrarian.net/32117987/BUG396387%20addresses%20only.txt -- Unable to resolve VPN names AND connect to the Internet https://bugs.launchpad.net/bugs/396387 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 396387] Re: Unable to resolve VPN names AND connect to the Internet
Without connecting via VPN, my work domain "svl.access-company.com" is still not resolvable by the sbcglobal's DNS servers. And yes, they are returning NXDOMAIN. ~$ nslookup svl.access-company.com Server: 68.94.156.1 Address:68.94.156.1#53 ** server can't find svl.access-company.com: NXDOMAIN But what I don't understand is why this all worked in 8.10 and not 9.04. So I fired up an ubuntu64 8.10 live CD I had lying around and created my work VPN connection. After a few tests, I see that the difference is in /etc/resolv.conf. See the attached file for the results. So I think the cause of my original bug is that in 9.04, my work DNS servers were placed AFTER my sbcglobal.net DNS servers, whereas in 8.10, they were placed BEFORE my sbcglobal.net DNS servers. Also, I don't understand why there is now a differently formatted resolv.conf on my ubuntu64 PC. Any ideas? ** Attachment added: "8.10 vs 9.04.txt" http://launchpadlibrarian.net/35390022/8.10%20vs%209.04.txt -- Unable to resolve VPN names AND connect to the Internet https://bugs.launchpad.net/bugs/396387 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 396387] Re: Unable to resolve VPN names AND connect to the Internet
System -> Preferences -> Network Connections -> VPN tab -> Edit (my VPN connection) -> IPv4 Settings tab. The Method is set to Automatic (VPN). The DNS Servers and Search Domains are empty (and disabled anyway). When I am NOT connected via VPN: $ grep -R 192 /etc/resolvconf/ When I am connected via VPN: $ grep -R 192 /etc/resolvconf/ /etc/resolvconf/run/interface/NetworkManager:nameserver 192.168.101.5 /etc/resolvconf/run/interface/NetworkManager:nameserver 192.168.101.11 /etc/resolvconf/run/resolv.conf:nameserver 192.168.101.5 I think I figured out what the difference is between my Jaunty32 (which puts my work DNS below my ISP DNS) and my Jaunty64 (which puts my work DNS above my ISP DNS). On my Jaunty64, my /etc/resolv.conf is an actual text file. On my Jaunty32, my /etc/resolv.conf turned out to be a symlink to /etc/resolvconf/run/resolv.conf. When I renamed my /etc/resolv.conf to a different name (/etc/resolv.conf.symlink) and rebooted, a new /etc/resolv.conf text file was generated. This text file has the same formatting as the resolv.conf on my Jaunty64: # Generated by NetworkManager instead of: # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) Furthermore, when I am connected via VPN, my work DNS servers are now correctly placed above my ISP DNS, so I can both connect to my work PC by computer name, AND surf the Internet at the same time. To summarize my entire fix: 1. System -> Preferences -> Network Connections -> VPN tab -> Edit (my VPN connection) -> IPv4 Settings tab -> Routes Make sure "Use this connection only for resources on its network" is checked. 2. Determine if resolv.conf is a symlink. If it is NOT a symlink, then the problem may be something else. file /etc/resolv.conf 3. If it is a symlink to `/etc/resolvconf/run/resolv.conf', rename it to something else: sudo mv /etc/resolv.conf /etc/resolv.conf.symlink 4. Reboot. 5. Test and see if you can surf the Internet and connect to your VPN PCs. 6. If test was successful, you can delete /etc/resolv.conf.symlink: sudo rm /etc/resolv.conf.symlink -- Unable to resolve VPN names AND connect to the Internet https://bugs.launchpad.net/bugs/396387 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

apport information ** Tags added: apport-collected oneiric ** Description changed: Summary: Ubuntu 10.04 hangs when the CPU scaling governor is set to "ondemand", "conservative", or "userspace" at 1000 MHz and 900 MHz. Other freqs don't hang. Motherboard: Jetway NF77-N1G6-LF CPU: VIA Nano processor L2200@1600MHz Ubuntu installer: Ubuntu 10.04.1 64-bit alternate Test setup: - Install Ubuntu 10.04.1 64-bit from an alternate CD or an alternate USB stick. - As soon as you reach the login screen, quickly press CTRL+ALT+F6 to go to a terminal, then quickly type "sudo chmod -x /etc/init.d/ondemand". The quickly type "sudo reboot" to reboot the computer. This will disable the ondemand script from changing the cpu governor on the next boot. - On the next boot, log in normally, then update all packages from the Update Manager, and reboot if necessary. - Launch a Terminal window. All test cmds will be executed from this directory: $ cd /sys/devices/system/cpu/cpu0/cpufreq - Open a 2nd Terminal window and execute this so you can watch the CPU freq. $ watch -n0 "cat /proc/cpuinfo" Test: - Check the available and current governor, the available freqs, and the scaling driver. $ cat scaling_available_governors conservative ondemand userspace powersave performance $ cat scaling_governor performance $ cat scaling_available_frequencies 160 140 130 120 110 100 90 80 $ cat scaling_driver acpi-cpufreq - Try powersave. The CPU drops to 800 MHz. No hang. $ echo -n powersave | sudo tee scaling_governor - Try ondemand. Ubuntu hangs after I press enter. $ echo -n ondemand | sudo tee scaling_governor - Reboot, then try conservative. Ubuntu hangs a moment after I press enter. I observed the CPU freq dropping to 1400 MHz, then 1300 MHz, 1200 MHz, 1100 MHz, then hang. $ echo -n conservative | sudo tee scaling_governor - Reboot, then try userspace. No hang at this point. CPU freq is 1600 MHz. $ echo -n userspace | sudo tee scaling_governor - Manually change the CPU freq. These changes don't hang. The CPU freq is correctly changed to the specified freq. $ echo -n 140 | sudo tee scaling_setspeed $ echo -n 130 | sudo tee scaling_setspeed $ echo -n 120 | sudo tee scaling_setspeed $ echo -n 110 | sudo tee scaling_setspeed - Now try 1000 MHz. This hangs instantly. $ echo -n 100 | sudo tee scaling_setspeed - Reboot, try 900 MHz. This hangs instantly. $ echo -n 90 | sudo tee scaling_setspeed - Reboot, try 800 MHz. CPU freq changed to 800 Mhz. No hang. $ echo -n 80 | sudo tee scaling_setspeed END OF TEST Other notes: - Some other info about my installation. $ uname -srvmpio Linux 2.6.32-32-generic #62-Ubuntu SMP Wed Apr 20 21:52:38 UTC 2011 x86_64 unknown unknown GNU/Linux $ lsb_release -rd Description: Ubuntu 10.04.2 LTS Release: 10.04 $ apt-cache policy linux-image-generic linux-image-generic: Installed: 2.6.32.32.38 Candidate: 2.6.32.32.38 Version table: *** 2.6.32.32.38 0 500 http://us.archive.ubuntu.com/ubuntu/ lucid-updates/main Packages 500 http://security.ubuntu.com/ubuntu/ lucid-security/main Packages 100 /var/lib/dpkg/status 2.6.32.21.22 0 500 http://us.archive.ubuntu.com/ubuntu/ lucid/main Packages - If the CPU is already at 800 MHz, "ondemand" sometimes doesn't hang instantly.

[Bug 805205] Re: VIA Nano hangs on some CPU scaling governors
Note: For some reason, the ubuntu/xubuntu 11.10 alternate installer kernel panics when I tried a USB install. I used an xubuntu 11.04 installer, then upgraded all of the 11.04 packages, then upgraded to xubuntu 11.10.

[Bug 805205] Re: VIA Nano hangs on some CPU scaling governors
- I installed liunx-crashdump on my xubuntu 11.10 system. Based on what I've read it sounds like this package is supposed to generate an apport prompt on the next reboot, but nothing happened. - I have attached the file "kern.log" from the hang. I triggered the hang on "Mar 31 22:49:30", but nothing was written to kern.log at that moment. - I cannot supply a digital photo of the screen because there's nothing unusual to show. The desktop simply "freezes" as soon as I hit Enter on the command "echo -n 100 | sudo tee scaling_setspeed". My keyboard's Caps Lock and Scroll Lock doesn't even rapidly blink on the hang. - I set up a netconsole session and verified that the "receiver" was receiving kernel messages from the "sender", my xubuntu 11.10 computer. However, when I triggered the hang, the receiver showed nothing. ** Attachment added: "kern.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/805205/+attachment/2980401/+files/kern.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/805205 Title: VIA Nano hangs on some CPU scaling governors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/805205/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 805205] Re: VIA Nano hangs on some CPU scaling governors
Well, I feel like an idiot. A BIOS update should have been one of the things I check for before filing the bug. The only problem is that updating the BIOS appears to require a bootable DOS floppy disk, and it's been a LOOONG time since I needed one of those. Anyway, I will try to figure something out and update this bug when I do. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/805205 Title: VIA Nano hangs on some CPU scaling governors To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/805205/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have updated the BIOS, and "ondemand" now works without hanging, as well as 1000 MHz and 900 MHz. Thanks for your help.

[Bug 805205] [NEW] VIA Nano hangs on some CPU scaling governors
Public bug reported: Summary: Ubuntu 10.04 hangs when the CPU scaling governor is set to "ondemand", "conservative", or "userspace" at 1000 MHz and 900 MHz. Other freqs don't hang. Motherboard: Jetway NF77-N1G6-LF CPU: VIA Nano processor L2200@1600MHz Ubuntu installer: Ubuntu 10.04.1 64-bit alternate Test setup: - Install Ubuntu 10.04.1 64-bit from an alternate CD or an alternate USB stick. - As soon as you reach the login screen, quickly press CTRL+ALT+F6 to go to a terminal, then quickly type "sudo chmod -x /etc/init.d/ondemand". The quickly type "sudo reboot" to reboot the computer. This will disable the ondemand script from changing the cpu governor on the next boot. - On the next boot, log in normally, then update all packages from the Update Manager, and reboot if necessary. - Launch a Terminal window. All test cmds will be executed from this directory: $ cd /sys/devices/system/cpu/cpu0/cpufreq - Open a 2nd Terminal window and execute this so you can watch the CPU freq. $ watch -n0 "cat /proc/cpuinfo" Test: - Check the available and current governor, the available freqs, and the scaling driver. $ cat scaling_available_governors conservative ondemand userspace powersave performance $ cat scaling_governor performance $ cat scaling_available_frequencies 160 140 130 120 110 100 90 80 $ cat scaling_driver acpi-cpufreq - Try powersave. The CPU drops to 800 MHz. No hang. $ echo -n powersave | sudo tee scaling_governor - Try ondemand. Ubuntu hangs after I press enter. $ echo -n ondemand | sudo tee scaling_governor - Reboot, then try conservative. Ubuntu hangs a moment after I press enter. I observed the CPU freq dropping to 1400 MHz, then 1300 MHz, 1200 MHz, 1100 MHz, then hang. $ echo -n conservative | sudo tee scaling_governor - Reboot, then try userspace. No hang at this point. CPU freq is 1600 MHz. $ echo -n userspace | sudo tee scaling_governor - Manually change the CPU freq. These changes don't hang. The CPU freq is correctly changed to the specified freq. $ echo -n 140 | sudo tee scaling_setspeed $ echo -n 130 | sudo tee scaling_setspeed $ echo -n 120 | sudo tee scaling_setspeed $ echo -n 110 | sudo tee scaling_setspeed - Now try 1000 MHz. This hangs instantly. $ echo -n 100 | sudo tee scaling_setspeed - Reboot, try 900 MHz. This hangs instantly. $ echo -n 90 | sudo tee scaling_setspeed - Reboot, try 800 MHz. CPU freq changed to 800 Mhz. No hang. $ echo -n 80 | sudo tee scaling_setspeed END OF TEST Other notes: - Some other info about my installation. $ uname -srvmpio Linux 2.6.32-32-generic #62-Ubuntu SMP Wed Apr 20 21:52:38 UTC 2011 x86_64 unknown unknown GNU/Linux $ lsb_release -rd Description:Ubuntu 10.04.2 LTS Release:10.04 $ apt-cache policy linux-image-generic linux-image-generic: Installed: 2.6.32.32.38 Candidate: 2.6.32.32.38 Version table: *** 2.6.32.32.38 0 500 http://us.archive.ubuntu.com/ubuntu/ lucid-updates/main Packages 500 http://security.ubuntu.com/ubuntu/ lucid-security/main Packages 100 /var/lib/dpkg/status 2.6.32.21.22 0 500 http://us.archive.ubuntu.com/ubuntu/ lucid/main Packages - If the CPU is already at 800 MHz, "ondemand" sometimes doesn't hang instantly. My guess is that the hang occurs when a process in the background pushes the CPU to 1600 MHz, then ondemand hangs when it tries to quickly scale the CPU freq back down to 800 MHz. - I have a different motherboard that also has a VIA Nano L2200 CPU. The board is a VIA VB8001. There is no problem with ondemand on that board because "/sys/devices/system/cpu/cpu0/cpufreq" doesn't even exist.
