I configured and tested the config (by 'service dnsmasq configtest') of dnsmasq and I got the message 'dnsdomain:host unknown (translation of the real message : hte inconnu) and I didn't find where I could define this host !

View 4 Replies View RelatedHow often are dns queries sent? Assume I want to connect to a ssh server, will I send one dns-query in order to do that or do I send multiple during my connection? What if I request web-pages, do I send a query only when I enter a site or will I send queries every time I visit a new page on that site?
I'm asking since I'm considering getting an account at dyn.com (the standard account for $30/yr) and it comes with 600 000 queries per month (which is way more than I expect to get but knowing exactly what it means is always good).
I set up a routed OpenVPN server. Everything works fine. But I'd like to route the DNS queries thru the tunnel too. So I added:
[Code]....
Can't find server name for address 10.8.0.1: Non-existent domain Even thou I have a DNS server set up correctly (on the same server as the VPN) with recursion. I verified that by sending queries form external source, which worked fine. I suspect that the Bind server doesn't listen to the tun0-interface only eth0, but the Bind manual says it should listen to all interfaces by default. The server log shows:
Code:
named[9639]: client 10.8.0.10#3807: RFC 1918 response from Internet for 1.0.8.10.in-addr.arpa
How do I get these DNS queries to resolve thru the tunnel?

I was using my ISP's DNS server. When I would ping something that doesn't exist, e.g. blahtest.com, it would reply anyway. When I tried to go to the site in a browser, it was some page like "I hope we can help you find what you're looking for". I thought that was ridiculous, so I changed to OpenDNS's DNS server.

View 3 Replies View RelatedIn Ubuntu 10.04 all I had to do was turn on my external hard drive and it would automatically be detected and mounted. I just switched over to Ultimate Edition, which I think is Ubuntu 10.04 with a lot of stuff added on to it. The funny thing is when I turn on the external hard drive it doesn't get mounted, and I don't think it's even being detected. I looked in gparted and it doesn't show up there. If I boot into Ubuntu 10.04 and turn on the hard drive it still gets detected and mounted, so there's nothing wrong with it. Ultimate Edition can detect other things connected to USB, like my iPod, so I'm wondering why it can't detect my hard drive.
Edit: When I do tail -f /var/log/messages and if the drive gets detected, this is what it says:

Update 6th March 2010: Update to Kernel 2.6.31-20 SOLVED the problem. Recording works again (still wouldn't in kernels 2.6.31-17 to 2.6.31-19). If a kernel update doesn't solve your problem, please read post 14 on page 2 by Mocha which seems to have solved the problem for other users without updating the kernel
Update 8th February 2010 to Kernel 2.6.31-19 did not solve the problem, please also read post number 7 for more details.
Quick Conclusion for other users who might experience the same problem:
After an update to kernel version 2.6.31-17 in Ubuntu 9.10 Karmic Koala, my external microphone did not work anymore. Playback was possible, just recording would not work anymore, although there was quite some background noise in the headphones. This made it impossible for me to use Skype and/or Sound Recorder.
All the possible solutions offered below did not help in my case (although you might give them a try).
I switched back to kernel version 2.6.31-16 where the problem does not occur.
Output: cat /proc/asound/card0/codec#* | grep Codec
Realtek ALC662 rev1
I know there are lots of threads about this topic, but I have spent hours on this problem already and none of the solutions offered so far worked for me so I decided to start this thread.
I have been using Ubuntu 9.10 and so far, my external microphone worked flawlessly in Skype as well as in Sound Recorder. A few days ago, I received a call on Skype and all the guy on the other side could hear was loud noise. I can only play sound, but not record anymore (i.e. the microphone doesn't work anymore). I tried two different microphones just to be sure whether one was defective and also checked it in Windows (where they both work).
I am not sure what might have caused this problem, I just remember a kernel upgrade about that time (not sure whether this is the reason though). I use 2.6.31-17-generic now.
Here is what I have tried so far:
1) Right-click on the Sound Icon in the top right corner and checked the following: in the hardware tab, it is set to analog stereo duplex, input is set to internal audio analog stereo (no other choice here) and the mic is NOT muted (playing with the volume doesn't help either) and output is set to internal audio analog stereo (again, no other choice) and connector is set to analog output (here I can switch to analog headphones or analog speaker, but makes no difference).
I remember that I could choose between Microphone 1 and Microphone 2 in the input tab; this is somehow magically gone.
2) Installed padevchooser, tried several settings to no avail
3) When I use "alsamixer" (version 1.0.20) in a terminal, Playback>Master is set to 100<>100, Capture is set to 150<>150, lowering and/or playing with these figures doesn't help either.
When I use "alsamixer -Dhw:0" in a terminal, I get the same results as in step four.
4) In Gnome Alsa Mixer, only "Beep" is muted, everything else is set to max. I have Master, Headphon, PCM, Front, Front Mi (x2), Lin, Mic, Mic Boost, Capture (x2, set to record), Beep, Speaker
I have tried to mute/unmute different setting to no avail. Now I wonder why I have two Front Mi and two Capture entries. This is different than it used to be, might this be causing the problem?
5) Fiddling with Pulse Audio Volume Control didn't help either.
6) Had a look at "paman" (pulse audio manager), not sure whether I should change anything here.
7) Installed "linux-backports-modules-alsa-karmic-generic" and rebooted as recommended in several threads, did not help either.
Added the parameters "model=auto" and "probe_mask=1" to '/etc/modprobe.d/alsa-base.conf', did not work, so I deleted the entries again (hint from [url], see post 5)
Now I am at my wits end. I need my microphone to work, especially for Skype, otherwise I have to switch to Windows every time I receive or want to make a call which is definitely not a long-term solution?
Does anybody have an idea what might be causing this problem? As I said, it used to work flawlessly just a few days ago and now I don't even know what I should do next to make it work again...
Output of "amixer"
When I run "alsactl init" I get the following result which might be at least a part of the problem, but I wouldn't know how to solve this problem:
Unknown hardware: "HDA-Intel" "Realtek ALC662 rev1" "HDA:10ec0662,103c303a,00100101" "0x103c" "0x303a"

View 9 Replies View RelatedI have a hard time mounting two external drives on my Suse 11.3. When I use the device notifier gadget both drives get mounted in /media/<drive name>, the vfat drive is read-only though. However, I would like to mount both drives under /<drive name> in separate directories and rw. I looked at the devices in /dev/ and entered the device name to fstab, set the mount point, file system (vfat, and ntfs-3g) and set 'rw,noauto,exec,user,sync 0 0'.
This way I could mount my vfat drive read-only under /<drive name>, but not the ntfs one. After a reboot i noticed that the external drives get different IDs in /dev. E.g. what I had in my fstab under /dev/sdc1 got /dev/sdf1, and /dev/sdc was unknown. I am doing something wrong here, what worked in 11.0 does not seem to work here.

View 3 Replies View RelatedMy wife (naturally without consulting me) purchased a WDC "My PassPort" portable usb drive to backup her Windows 7 machine at work. It has an NTFS partition and should be accessable from a Linux box, but she choose to password protect the drive. This apparently requires an executable to run before the drive is unlocked. WDC has provided Windows and Mac versions of their unlock utility, but when I called told they said WDC doesn't support Linux.
It seems odd to me. Are we such a small community that they just don't care? I could remove the password protection and it would probably work with linux. I own a WDC "My Book" external usb/firewire drive that works fine under linux. Just curious why they don't care enough about us to have an linux unlock program. While on the subject I will mention that this drive comes preformated with a virtual CD as one of the partitions. This is a new feature to me. I have not yet attempted to connect via linux to see what happens.
All our CentOS servers sync to a windows domain time server and we're migrating to a new CentOS time server. however in testing the setup with the clients I get the following
