Ubuntu Servers :: Setup Real-time (or Near Real-time) Folder Synchronization Among 2+ Servers
Mar 23, 2010what the recommended way to set up real-time (or near real-time) folder synchronization among 2+ servers. I looked a rsync but that doesn't sound real-time and it looks like its something that you might put in a cron once an hour.

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.

General :: Ubuntu: Tool For Displaying Disk Activity In General And By Process?
Oct 12, 2010My Ubuntu system is occasionally becoming very sluggish. I'm running many things simultaneously and it's very difficult to tell which program is the culprit.
I suspect that the sluggishness is due to disk activity since the CPU usage is consistently under 50% on each of the 4 cores of the CPU, and over 30% of the 6GB of RAM are free.
Is there a tool that can show me in real time the number of disk IO operations per second and the amount of data read/written per second? Can all this info be broken down and displayed per process?

View 3 Replies View RelatedGeneral :: Real-time Sync File Between Machines?
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..
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).
General :: Review The Boot-time Info That's Going To The Console?
Feb 18, 2011I'd really like to be able to examine all the information that flys off the top of my terminal when my system boots (off of fd0, the only way I've done it, so far): review of "similar threads" yields nothing; seemingly not a man pages item; have not found any how-to's that cover this; the daemons for logging are third-to-the-last before logon prompt (and still displayed, the ONLY reason I know THAT); seems like it should be a compile-time sw-switch settng (sub-optimal since I'm still not comfortable with compiling kernels); but I was hoping it's already being captured in some log file somewhere that I'm as yet unaware exists. I do realize that if I had a printing console, this would be unnecessary.

During disk activity it sometimes becomes completely unresponsive. The mouse cursor doesn't even move. It actually seems fine when it first boots up, but it gradually gets worse as I use the computer for a while until it eventually becomes completely unusable. I'm only having trouble on the one system.The drive in the system is SATA, and I already checked to make sure DMA was on. It is a x86_64 kernel.I tried adding noapic to the kernel boot line after some googling, but it seemed to have no effect

No reaction on pressing 'return' 3. The disk led showed no activity, so I reseted the computer after 5 minutes inactivity. The system came up but with F14. I repeated the 'preupgrade' and all messages are in [URL]... but still F14 comes up after reboot. Where have I missed ... eager to get F15
View 4 Replies View RelatedUbuntu :: Karmic Keyboard/mouse Lag On Disk Activity
Mar 6, 2010I recently switched to 64-bit Karmic after installing extra memory. I have everything working fine, but I am experiencing an annoying lag in keyboard and mouse response whenever any of the CPU cores briefly jumps to 100% usage, which tends to happen every 10 to 15 seconds, usually caused by firefox.
I'll be typing or scrolling, and there is fairly regularly a hesitation of a second or two in which nothing happens on-screen, and then everything catches up again, ie the keyboard buffer empties to screen or the page scrolls a lot.
I've tried changing the Nvidia driver and the disk iosched elevator, which were the only ideas I could find when searching on this issue.
It seems to me that (a) the CPU usage shouldn't be jumping up like that, and (b) even if it does, it shouldn't affect keyboard an mouse activity to such an extent. This only started happening after switching from 32-bit to 64-bit Karmic.

Ubuntu :: Constant Disk Activity - Light Flashes About Twice Per Second
Apr 6, 2011I understand that Ubuntu typically has some disk activity even when idle, but I believe that I have a problem that I am worried is affecting my disk drive - which has recently become quite loud. The system disk activity light flashes about twice per second, all the time, when idle. iostat shows a Blk_wrtn/s of between 10 and 40. I am running Lucid x64. The system disk uses ext4 for root and ext4 for /home. The disk activity starts before I even log in. There is no disk activity if I drop to the root shell in recovery mode - as seen by no flashing light and iostat writes = 0. I have tried killing my media server processes, Mediatomb and Squeezeboxserver. I have unmounted the ntfs data drive. There is nothing else running beyond the vanilla install to my recollection other the services above that I stopped. How can I determine which process is causing the constant writing? I do not have this issue on my laptop which is running Karmic, and as I mentioned earlier, I think this non-stop activity is damaging my drive.

Nov 12, 2010For about 15 minutes or so after login on my FreeBSD 8.1 (yes, I know its not Linux) the hard drive goes absolutely crazy with activity. So much so that it takes a while for the ls command to read the contents of the directory. But after the 15 minutes or so the disk activity calms down and returns to normal.
Im thinking it is some sort of fsck command, but I am unsure where or how to disable it. The hard drive is connected via sata to the mobo. Im not quite sure what other info I can post to find out what is going on. Just tell me what other info is needed and Ill post it up.
