General :: Enhanced Real Time Clock Support - Missing Kernel Option
Jul 6, 2011In regards to compiling a custom kernel:
When using make menuconfig - under Device Drivers --> Character Devices --> there should be an option with the label "Enhanced Real Time Clock Support" (CONFIG_JS_RTC).
The problem is that this option seems to only show up while using the menu method when other options are either enabled or disabled and I've entirely forgotten what should be what. I swear fingered it out once.
This is on an older computer (P4) so HPET is no good.
You would think that disabling the HPET option would enable the RTC option but that does not appear to be the case.
I understand I can just add the option to the .config file and avoid this hassle but I'm very interested to know how to make this work.
To show my appreciation I will do something nice for you such as call you a nice name or tell you that you are pretty (or ugly if that's what you prefer).

Sep 25, 2010I have the latest release of Lucid Lynx installed. I want to try out audio recording on Linux so I want to know if it's possible to use a real time kernel with Lucid. So I installed the 2.6.31 real time kernel. It shows up in GRUB, but when I boot it gives me the message:
mounting none on /dev failed No such device
It then takes me to the login screen, and once I enter my password it just takes me back to the login.
Ubuntu Installation :: GRUB Menu, And Can't Boot To The Real-time Kernel?
Mar 14, 2010I'm a very new Linux user, so speak slowly and don't use big words. I installed Karmic from the Live CD. It is the only OS in use on this system. I then upgraded to Ubuntu Studio using the instructions found on the wiki.
On bootup, I get a brief message stating "GRUB loading" and then the system automatically boots to the generic kernel. No GRUB menu is ever displayed. I would like the option to boot to the real-time kernel, but I have no idea how to edit the appropriate files. I've done a fair amount of reading on the subject, but I find very little information relating directly to the real-time kernel, and so I still feel like I'm too green to do it without messing something up.
Ubuntu :: Can't Get Newest Real Time Kernel To Show Up In Grub 2 (Karmic)?
Apr 26, 2010I want to try out the realtime kernel to get my audio latency down. I have installed the realtime kernel packages according to the Ubuntu Studio preparation documentation here - I have also run sudo update-grubHowever, when I boot up, the realtime kernel option does not show up in grub2. The current kernel I am using is 2.6.31-17, but the only options in grub for it are -386 and -generic.
There is a previous entry of 2.6.31-9-rt which I had attempted to use previously (sometime last year) but if I select it, it doesn't even boot at all.I checked my /boot directory and there is no vmlinuz-2.6.31-17-rt file .... Which I am assuming is why it doesn't show up or add when I run update-grub ... But I am currently at a loss for how to actually get the 2.6.31-17 realtime kernel file and add it to grub2.

Dec 7, 2009I've got the following problem:
1. I start two bash windows
2. In one of them I start a script test1:
Code:
This script puts a natural number 5 times a second.
3. Then in the second bash window I type (as root):
Code:
The script test2 looks as follows:
Code:
While true; do
true;
done
During the following 15 seconds test2 is the process with the highest real-time priority. As far as I know the script doesn't perform any system calls so it shouldn't be suspended even for a minimal timeslice. My question is: why the process test1 manages to put a few numbers on the screen before test2 stops. I thought that test2 would exclusivly own the processor for 15 seconds.

Jul 15, 2010I have a few servers that are exposed to the internet. When someone tried to brute force hack in to the ssh, ossec adds their IP to the hosts.deny. Then the hacker (read: script kiddie) moves to the next IP up the line and hits my next server, etc, etc.
I end up getting 20 emails for all the servers that they hit.
My question, is there anyway to sync the hosts.deny file across multiple servers so that if they are locked out of one, they are locked out of all?

Software :: Convert Unix Time To 'real' Time
Jan 28, 2010I used the following command to get the unix time of root user creation:
Code:
awk -F":" '$1 == "root" {print $3}' /etc/shadow
How can i convert this into the date/time of creation?
I am writing a shell script, which determines the OS installation date among other stuff, and i am assuming the root user's account creation date should be a pretty accurate pointer. Are there reasons why i should not be assuming so?I would be open to other suggestion for getting this date/time, but it would nevertheless be interesting to convert the unix time to "real" time without doing complex manual(or otherwise) computation..

Feb 11, 2010I have a system running openSUSE 11.2 with Desktop and XEN kernel, as well as Windows 7 (not by choice though...). I have noticed a strange time issue, with Windows 7 and the desktop kernel the time is correct (like for example now: 1:32 PM) but in the XEN kernel it is ahead several hours (6:32 PM). If it was an issue between openSUSE and windows then I would think that it is a problem with the system clock but I don't know what would cause a time issue between kernels like that.
