Ubuntu Servers :: Server Is Partially Unresponsive?
Jul 16, 2010
I have a remote server which has been working perfectly for about 1 year. It is in a secure location and used for serving a local web-app, and we remote administer it through an OpenVPN tunnel, and previously a Hamachi tunnel.It has in the last few days become partially unresponsive. What I mean is that I can ping it fine through the VPN, and I can SSH into the box, but when I try to run some commands, it seems to freeze partway through, and I get the output interrupted and a blinking cursor. I have also tried to access the web-app through the VPN and while the page header in the browser changes to the correct page name, the actual page does not load.A reboot does not seem to have cleared the problem, although I cannot be certain at this moment that the reboot command actually completed, or froze partway through

I have an Ubuntu server running with lighttpd.
The file, access.log has utilized 73GB at: logs/lighttpd/, which contains data since 3 to 4 years (approx.)
So, i need to have only last 6 months logs in the file and the rest to be cleared.

Kernel version: 2.6.26-2-686
Java version: 1.6.0_0
I'm going to run a full system update, but I doubt that'll work.
What happens is I turn the computer on, log in, start the application with:
java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui
and it will work fine for a while, but then, while we're playing, it'll become unresponsive and crash. I then go over to the physical computer, wake the monitor up by pressing the down arrow, delete the "[[B" that appears, and try to issue the applications stop command to save and close the application. This doesn't work. The computer registers what I type and registers the return, but nothing happens. I switch over to my second console, log in, find the PID of java, and attempt to kill the java process as root. It accepts the command and gives me another line of prompt, but when I switch back to the first console, nothing has happened.
I then switch back and try to issue a shutdown for right now, and it'll get to "Sending processes the SIGTERM signal", and then it waits for them to be killed, but will not progress further than that. I then have to either force the shutdown with the 3-second hold for the power button, or I have to turn off the power bar it's attached to.
Also, if I'm at the prompt and press backspace, which gives me a system beep, it doesn't stop. Instead of one, short beep, I get a never-ending tone, as opposed to the beep.
The computer does run a little hot; It's in a closet and it's kind of crammed, but it's never so hot that you can't handle the computer.

I'm running an English language Ubuntu 10.10 and after a fresh installation, I installed support for the Spanish language via Administration> Language Support. After unistalling that language it still keeps ramdonly appearing in some parts of the system. For example in System>Administration>Configuracion del cortafuegos (Firewall configuration) (!!!!). Another example is in the terminal. The biggest part of it is in English, however all the lines that show, for example when installing a package, are in Spanish

I'm actually using both system, Ubuntu 9.04 and Windows XP, I got an HDD Western Digital (WD4000YR) with 400GB capacity, I have this weird problem (confirmed on other MoBo's with the same problem):
Power on the PC > In BIOS, disk capacity is 150GB > Start on Linux > In linux, disk capacity is correctly display: 400GB > Reboot > Start on Windows > disk capacity is correctly display: 400GB
BUT IF
Power on the PC > In BIOS, disk capacity is 150GB > Start on WINDOWS > in Windows, disk capacity is incorrectly display: 150GB
Linux its the solution to my problems, if I start on linux and then i REBOOT to windows works fine, but it doesn't if I turn OFF the PC. I need both systems due to incompatible software. My question is: Why in LINUX the disk works fine and if I reboot the disk continues doing just fine? What linux do that windows doesn't on the disk thing? I though maybe adding a line in windows option of the GRUB or something.
What I tried:
Fill with zeros using the WD tool, resign and format in Windows
Fill with zeros using the WD tool, resign and format in Linux
Format in Windows
Format in Linux
I have to say that the disk works great, when I do that (start linux then reboot to windows) the disk works just great, I had large movie files in there and works. So maybe the disk its not.

Since installing Lucid LYNX LTS on my Netbook. (See: [URL] [#136]). Via USB, I can connect my iPhone 3GS. It gives me two simultaneous choices:
Open F-Spot and Open Rythmbox.
In addition, I can also "Open / Browse Folder". As such, I can view / import photos and videos made on the phone, as well as video PODCASTS. I can also play my music files
What I cannot do:
1) Play / find my purchased audiobooks [decryption not supported]
2) Locate the mp4 videos / movies (NOT encrypted) that I transferred to the phone via iTunes on my MacBook.
3) Send a file via bluetooth to the phone [the Indicator Applet does allow me go go as far as select the file. It gets to the point of "connecting" then "unknown error occurred"
I cannot sync the addressbook, calendar, or notes on the iPhone with my netbook. I have the following libraries installed:
ifuse
libmobiledevice-utils
libmobiledevice0
libplist++1
libplist1
libusbmuxd1
python-imobildevice
usbmuxd
NOTA BENE: This phone is NOT jail-broken.

I have a script that pops up a jpg file several times a day as a reminder. The script is called up by crontab and it works perfectly.The issue is that I want the script to also perform a system "beep" in addition to popping up the jpg file. When I test it on the command line everything works but when I run it in cron the jpg file pops up but the beep doesn't beep. I'm thinking the problem is in the "echo -e \a" part. I must be missing something.Here is my script:
#!/bin/bash
echo -e \a
sleep01; echo -e \a

I just tried to upgrade from 10.04 to 10.10, but since update-manager did not show the upgrade button (for some reason it did not know that there was a new release?), I tried upgrading using sudo do-release-upgrade.This only worked partially though, and now when I run lsb_release -a it says that I am running maverick, but when I try to run update-manager, it says that the upgrade was only completed partially, and it suggests that I try to finish the upgrade, but it then gets the following error:"An upgrade from "maverick" to "lucid" is not supported with this tool"

My recent install of 11.2/KDE on a laptop suffers from a strange misbehaviour of the compose key (I have declared the Windows and Menu keys as Compose). It appears that two different sets of composing sequences are active, depending on the application.
I have to explain that I use a lot of unusual characters on a regular basis and therefore keep adding more sequences to /usr/share/X11/locale/en_US.UTF-8/Compose. I have even redeclared a couple of predefined sequences to values that are more useful for me. All these work fine, for example in a terminal window (konsole or xterm) or in konqueror, or even in OpenOffice.
However, other applictions seam only able to handle the default set of Compose sequences. This applies, for example, to Firefox or Gimp. It does not matter whether they are invoked from the command line or from a desktop icon. I tried both the Firefox shipped with OpenSuse, and a download from mozilla.org: Same result.
I tried to delete other Compose files from /usr/share/X11/locale/* but it did not help. I wonder where the default rules are actually found after deleting all the Compose files, even if (for some reason) the locales have changed in these applications.

I hit some trouble upgrading from FC 10 to FC 12 using the netinst CD. I had previously successfully upgraded the system from FC5 to FC10 with the same method - that time everything went well. At first the upgrade went well - the installation program found my FC installation and detected the partitions right. The problem appeared when about 90% of the rpm's were installed. Anaconda was complaining about a fatal error with a package and quit.
After rebooting and restarting the installation program it does not recognize my partitions anymore and suggests I'd format them for a fresh installation. As all my data is there I'd rather not do that. I then rebooted again and chose "Repair" from the installation menu. I got to the console and noticed that all partitions mounted cleanly and all the data seems to be there. Trying to reboot from the hard disk almost works. The system gets up, goes through grub, gets the kernel running and mounts the disks but fails to launch Xorg.
I get to a terminal login from here by pressing Ctrl+Alt+F2. When I type the user name and press enter the terminal seems to crash - does not ask for the password but simply returns to the user name query. An error message flashes just after pressing enter but too quickly for me to read. When I boot from CD again and go to the terminal via the "Repair" option the previous events can be seen from /var/log/messages. Xorg tries to start and stops trying after a certain amount of failures. After that it says this:
Code:
init: prefdm main process (2123) terminated with status 1
init: prefdm main process ended, respawning
init: prefdm respawning too fast,stopped
[code]....
My best guess is that this happens because the upgrade was aborted before it completed and hence some necessary rpm's were left out. I figured I could possibly fix this by updating the packages with yum from the terminal if I got to log in. What should I do now? Could I for example try and manually copy some missing files to the disk as I can access it via the repair option?

I installed 10.04 onto an old dell and its was running great, internet etc.. I then had my home desktop crash and said great, let me bring the dell home so the wife can use it. At home, i have a wireless card ( Netgear WG311 ) that I then installed into the Dell. Being that she was needing to use it online right away, I searched for the first install as it was not detected, and used used synaptic to install the bcmwl-kernal-source as that was the prefer ed driver for Netgear. So now that I installed that, not only have I not fixed the wireless issue, I now have no wired internet. I've been searching and re reading as many steps as I can, but am running out of time as she needs the computer tomorrow. Installed the ndwrapper ? but was not able to actually get the driver installed. All the other threads seem to be older ubuntu versions, and maybe its just me but the slight variation from one to the nex has me a little confuzed.

I have a (partially) formatted DVD+RW disc, and need to do a full format in order for wodim to be able to properly write to it, since wodim does not do DVD formatting automatically, despite what its man page says. (I want to write using wodim, NOT growisofs, since wodim has a -pad option for zero-padding, and the -pad option to growisofs doesn't work when burning an ISO file.) ,
wodim -v dev=/dev/dvd -format
doesn't work on an already partly formatted disc, only an unused one. And
dvd+rw-format -force=full /dev/dvd
doesn't work either, claiming the command-line option is unimplemented (even though the usage is documented). Is there any natural way to do this, or do I have to do something ugly, like using growisofs to write an exactly 4.7 GB file to the disc?

I run openSUSE 11.2 (kernel 2.6.31.12) and I use Wine 1.1.38 to play World of Warcraft from the konsole terminal application. For the most part this works okay, but there is one small issue that continues to annoy me:
Look at your keyboard (assuming standard QWERTY no-name keyboard) - see the key just left of your Backspace key? That key is only partially working for me in WoW. I cannot bind it to any action bar button in-game, with or without addons enabled. For some reason the key works fine when entering text into the chat console though.
I have used xev to get a bit of data on the key itself - not that it is that informative to me though, but the absence of the issue when playing WoW through Windows would suggest that it is somehow endemic to my Linux configuration:
Code:
KeyPress event, serial 34, synthetic NO, window 0x4a00001,
root 0x1a7, subw 0x0, time 6474080, (159,-10), root:(1364,15),
state 0x10, keycode 21 (keysym 0xfe51, dead_acute), same_screen YES,
XLookupString gives 2 bytes: (c2 b4) ""
XmbLookupString gives 0 bytes:
XFilterEvent returns: True

I need to overwrite the first say 50 or so lines of an xml file on an everyday basis. The first 50 lines of the file are always the same and the 50 lines they get replaced with are always the same. Is there a way to create a file with the 50 new lines and somehow copy/merge/overwrite the larger file such that the 50 original lines would be replaced but the remainder of the file would be untouched?This seems simple, there has to be a way to do it. I'm just not smart enough to figure it out.

I have a strange problem where my machine will suddenly stop responding to connections while still remaining partially connectible. Here's an example sequence of events I have taken (numerous times). If anyone can spot something else I should check or has seen these symptoms before please let me know.1) System is using an Edimax 7318-usg, Ubuntu 10.042) Wifi connection is working, with power management turned off (iwconfig)3) Signal strength does not cause the connection to drop (confirmed with router logs)4) When in a ssh session on the problem machine suddenly the ssh session is dropped "host is down"5) When I attempt to re-initiate ssh it fails, no route to host...6) Pinging it fails, accessing a webpage hosted on it fails, all access fails7) The machine I'm pinging/sshing from still has a good network connection8 ) I check my routers DHCP leases, problem machine still has a valid lease.
9) Router still shows problem machine in routing & arp table & shows active traffic going to and from (I checked the routers states and bandwidth monitor for this)10) I try sshing and pinging the problem machine from the laptop on the local network, it still fails, no route to host, wtf?11) I go to the problem machine physically, wifi connection is up with decent signal12) ifconfig indicates it still holds an IP address13) I open a browser on the problem machine, any webpage loads fine14) I ping the laptop from the problem machine, ok15) I ssh from the problem machine to my laptop, it works16) At this point I ssh from the laptop to the problem machine, sometimes it works sometimes it fails(it seems that pinging/sshing the laptop FROM the problem machine sometimes makes it connectable again).
17) Usually if I wait a while the problem machine will randomly become connectable again at random intervals18 ) The only reliable way to make the problem machine connectable again is manually reconnecting it to the wireless network19) I tailed auth.log ufw.log, etc. nothing suspicious disallowing my ssh connection20) dmesg shows nothing unusual, as far as I can tell, just some activity negotiating WPA keys and suchBy looking at the timestamp for the WPA negotiation and cross referencing the router bandwidth monitor I can tell the WPAnegotiation doesn't make it drop the conectionSo that's it, lol.

I installed the Unity Desktop Env. to play around with it on my wubi installation of Ubuntu 10.10. I have the log in screen disabled as well as the grub menu so it launches right into Ubuntu. I logged out and logged back in under Unity and could move the mouse but nothing would happen. I have gnome-panels disabled as well so alt f2 wont work even in my gnome DE. By disabling the log in screen and the grub menu have I painted myself into a corner so to speak and made this installation completely unrecoverable?

I have installed and run Ubuntu on my iMac, now I would like to try Kubuntu but the installer hangs every time inbetween step 1 setting language and step 2 choosing time zone. Sometimes it's while the system clock is being set, sometimes after. It's just the installer that is locked up, I can still move the cursor but because the installer is fullscreen I cannot get out of it, at least not that I know of.
I have made two different desktop CDs from two different ISOs and both gave the same exact behaviour. I think I prefer Kubuntu to Ubuntu but I haven't really been able to give it a try.

For some strange reason my gnome-terminal has become really slow and unresponsive.If I type anything on the terminal I have to wait a few seconds before anything appears on the terminal.Memory or cpu is not the problem. Currently I am using only about 20% of my CPU:s and 15% of my RAM..Booting didn't help.Lucky this doesnt happen in openoffice, firefox or gedit. (which I need most)and I am running 9.10, which has last been updated about a week ago.

On Dell Inspiron 9200, with or without accelerator for NVIDEA graphics. P.S. I would like to give 9.10 a chance. have gedit and browser open (browser with the forum message being edited), then do the following:
1.This example demonstrates one problem (unresponsive single click) Use the System-->Preferences-->Mouse
Click repeatedly on the light bulb at 1 second interval ---> result: often the light does not turn on. Result: it appears that the click event does not complete. I have noticed that a mouse-out will cause the click to complete (specifically as in 2. and 3 after a brief moment (hopefully before the drag and drop icon appears).
2. Click on any icon, submit button, close, etc. takes many tries.
3. Click on any icon, panel button, link, etc. if you linger a moment a floating icon (a drag and drop hand).
4. Scrollbar button and action follow the mouse outside of the scrollbar. The scrollbar sticks - difficult to make scrollbar stop following the mouse.
5. Example, have two visible windows (for example gedit and the browser) From gedit move to browser by click on browser. ---> result takes forever to recognise the focus and click and go to the broser.
6. Unresponsive UI. In browser highlight text in textarea (with difficulty) then chose Copy (slow UI), from this window click on desktop's Applications (takes many clicks to open), from Accessories click on gedit (slow or takes more than one try), paste (speed of paste OK).

I upgraded from 8.04 to 10.04, and most things appear to be fine. However, after a day or two of inactivity (apart from remotely logging in for SSH), the computer goes into a state where the screen is blank and it is unresponsive (and no longer allows access by SSH, FTP, or SVN server access). I have to reboot the computer to use it again, which I can't always do when I'm traveling. I inquired about this previously -but I'm convinced the solution may be more complicated than suggested because I don't have compiz turned on and the computer's power management is already set so that it's never supposed to sleep. I tried to install 10.04 fresh from a Live CD, but it freezes where it asks me how I want to use my partitions so I can't even reinstall

After an update (and a restart), everything has become extremely sluggish to respond to my mouse and keyboard. It takes around 6 seconds to change a tab in Firefox, even changing windows will take 2 seconds before the new window will respond to typing (anything I type in the meantime simply doesn't appear).
Here is Synaptic's history from yesterday, I was wondering if any of the version numbers look off to somebody, or if somebody knows which is the offending package:

From time to time my system will practically lock up. During these times there is near constant hard disk access, and applications will quit responding for 10-30 seconds at a time.Looking in the processes of System monitor it appears that beam.smp is the culprit, during these times it is using 80-95% cpu and between 2 and 3.5GB or RAM (I have 4GB total).It appears to be this bug: https://bugs.launchpad.net/ubuntu/+s...ng/+bug/458453I am using Ubuntu 10.04, 64-bit. I am also relatively current on my updates (I think the last updates I did were about three days ago).Judging from the comments, though it looks as if it was fixed back in May.I don't know if it matters, but the only thing I use evolution for it its integration to gnome-pilot to sync my old Palm m130.

Almost every day, for around 15-20 seconds, my computer becomes unresponsive, while the hard disk makes a strange periodic sound (period ~2 seconds, half of it the sound suggests very intense disk activity, the other half - normal disk activity), and the hard disk LED stays on (not flashing, just on). I ran manually all scripts in the /etc/cron.* folders. Only the mlocate script seemed to cause higher than normal disk activity (but still low enough to not cause problems). I still disabled it, but the problem persists.

Two fresh installs of maverick meerkat on my laptop. Both times, problems started immediately. Playing media files, web browsing with a few tabs, or running bittorrnet freezes my humble system.
At some point or another during a lockup, the active programs running use up all of my CPU and a sizable chunk of RAM. Then after a few minutes, it stops and goes back to running normally for a bit. There seems to be no common element that sparks this behavior. Anything I do causes my computer to freeze for 2 minutes. It seems to be a common issue as well, and I've been unable to resolve this substantial problem. Is there some bugfix I am missing?
