I have a problem with scrn and keyboard freezes. This time it only threatened to crash, and I've noticed something in /var/log/ mssge that might lead to a solution (if I understood it)
Apr 5 06:42:04 Den-mint kernel: [ 233.209761] EXT4-fs (sdc1): warning: mounting fs with errors, running e2fsck is recommended It's imediate context is below.
Last week my server crashed. I'm trying to diagnose the cause.
This is the relevant error message in /var/log/messages:
Code:
I'm assuming that I can conclude, then, that apache/httpd was the cause of the memory leak?
Next, I've been tracking my memory usage. Using top, this is an average memory load level for my server:
Code:
I'd like to confirm if my understanding of this data is correct, because Plesk indicates that my memory usage is only 50% or less. (Though I have read a number of reports indicating that Plesk's measurements are frequently wrong.)
Top says: Of the 2,073,156K total memory, 1,982,572K (95.63%) is being used, 90,584K (4.37%) is free. Of that sum, 421,948K (20.35%) are being used as buffers. Additionally, of the 2,096,472K of Swap, 60K is used, and 887,700K (42.34%) is cached.
My questions: Is my memory actually being 95% used? Or is the buffered quantity (20.35%) not a use of physical/virtual memory? (i.e. is it disk usage?) Does the amount of cached Swap influence the percentage of physical/virtual memory being used?
In other words, who is correct? Plesk says I'm using 40-50% of my memory, whereas top says 85-95%.
Every time I try updating my system to the new Debian stable, I end up with a system that no longer recognizes my burner and even though autofs was not updated, it is restarted and all of a sudden there's no map for it. This usually takes nothing more than updating Amarok to "stable", because libc6 must be updated. I've tried updating different programs and this is the one factor that remained the same when the autofs no maps issue cropped up. I am considering trying again. But testing the system upgrade on another partition, so I can get it right before using it on my "real" system.
Last time I made an attempt, I was able to make my burner and floppy drives visible under "computer" by adding both to the fstab file, and was even able play DVDs, CDs and floppies but the K3B burner would not recognize the burner and said hal was used to detect, but HAL was not updated -- I'm absolutely sure of this. The other burner program (Gnome Baker) would at least recognize and even named my burner, but could not burn a disk. I did update HAL afterwards, hoping to help the situation, but it improved nothing and may have made things worse. When I rebooted the next day I had no disk access whatever.
As I mentioned in the title, I believe upgrading to libc6 led to the trouble. Don't understand why. When I upgraded from old oldstable to the new old stable last year nothing bad happened. Would skipping over new "stable" libc6 and going for the new unstable work? If I could just solve this one problem, I could easily upgrade Dreamlinux 3.5 from Debian 5.0 to 6.0.1. That's where it was when I upgraded most of the system, before recognizing there was a disk recognition and mounting problem.
I'm new to deian and linux in general. I have a project to build a web server. All is going well - have LAMP configured and now reading/learning about security. I've just done a netstat -tuan to look at what ports I have open. It gave me this. I've managed to find out what a mojrity of the ports are...some i'm not sure of. Just wondering if anyone could enlighten me by answering a few questions on my notes:
1. what are the ports with ???. Can i disable them? 2. how comes some ports are listed twice? Do i need to disable them more than once. 3. Are the notes i've made correct...can i remove the ones I'm thinking of removing?
I'm looking to setup a transparent proxy, which (if I understand correctly) will allow me to monitor/control http traffic on my home lan with the use a log analyser.I'm planning on following this guide Yes... I'm cheap and don't wanna buy another NIC.My question: How does this all work? I get that http traffic goes to my server first, and then to the destination address, but how? What is stopping the other computers on my network from going straight to my router?Is my interpretation of a transparent proxy correct?
It's been freezing on me like you wouldn't believe today, and I think it has something to do with the load put on the CPU by various sites. The trouble is, I need to access a few of these sites to do my work. WordPress is one of them. I've had to restart the computer five times via SysRq keys since when these freezes happen, I can't Ctrl-Alt-Backspace out of it (even with zap enabled) and I can't bring up a terminal or Alt-F2 to kill process. I can't switch processes, windows, or anything. Firefox just sits there and laughs at me as I threaten to bust the screen in half.
And the real funny thing is, people actually say this is a better browser than IE. I never had these problems on Windows.What can I do to stop this? Do I just have to switch to another browser?
Does anyone have a suggestion for a very simple tool I could use to manage sales leads?
I said CRM in the title of this thread, but I don't really need anything that full-featured. All I want is something to help me manage my job search by keeping track of which jobs I have applied for, when I need to phone particular agencies again, and that sort of thing. I have tried installing a couple of Apache-based apps, but they have turned out to be too complicated to set up. I couldn't find a desktop app in the repos, but maybe I have missed something. A cloud-hosted service would probably be OK, so long as it is within my current �0 budget.
I have never had the packaged vsftpd start with the ssl_enable option set to YES. The mysql on those servers works just fine with SSL enabled. After reading there seems to be a different package available on rh5 repo. This server shows up to date with 2.0.5-12.el5_3.1. The rh5 list shows 2.0.5-16_el5 per this:[URL].. My question is, is there a set lead time till adoption of current RH packages or is just random? I have to have SSL_ftp running and didn't want to step out of the repo lists if possible.
I could really do with some help here, been using Ubuntu for a long time now but a very slow learner. I use windows but only for gaming. The problem I have is, last night I had all my systems working fine (Ubuntu Server Edition 10.10 (used to be 10.04 and 8.04 and always work fine) and Ubuntu 10.10 and Windows XP duel booted on my desktop). All of this worked absolutly worked fine. Last night I needed to reinstall windows on to a seperate HDD and so decided to swap the HDD's in but server and desktop over and fresh install it all. after doing so I did and installed Server edition on the desktop before swapping over due to know screen or keyboard for the server) this is when I first notice that it would not connect to my network. During install it picked up the DHCP but once install no connection dispite ifconfig reconising eth0. so I put the new HDD's in and removed the server HDD and installed windows the ubuntu.. when I booted ubuntu 10.04 on live cd, it reconise the connection but would not connect at all, since then I have tryed putting in a PCI network card as well and comes with the same results. the odd thing is, untill the reinstall it all worked fine and dandy and never had any problems. I have not tryed windows yet as I need to install the drivers for that but I will do that now and post with a answer as soon as I know if it works.
My sister's laptop (toshiba satellite l550 running lucid) often runs really, really slow, even after a fresh install. Going through the gnome main menu, everything just lags by several seconds. Closing applications often takes a while, etc. I've run top and iostat to determine what the problem is and it seems to be IO-related. User processes and system processes don't take up more than a few percent, but the average load is usually over 2 even when I'm barely doing anything. Top shows that, whenever everything slows down, the 'wait' criterion is pretty high.
Now, I've also tried installing lucid to an external USB hard drive and that works fine. I'm currently running the S.M.A.R.T. diagnostic and so far I've got the attached screenshot to show. Only the criterion shown and the 'current pending sector count' are showing warnings.Any thoughts? Could the performance issue be related to the hard drive warning? I'm not planning to replace the hard drive just yet, because this laptop still has a two-year warranty.
One of the (many many) problems that I had with Ubuntu 10.4 was that I wasn't able to connect using a wired. It really came to me as a huge surprise, because that's a problem that I have never encountered. I had dealings with wireless-issues in the past. But never a wired connection failed. The thing is that we (in the dormitory where I live) had a network problem recently. A hardware piece got fried and we weren't able to replace it for about 3 weeks (go figure :X ). But in the past 3 days or so we're back online. The thing is - none of my neighbours (all of them are using Windows) has network issues now. Usually it was on the contrary - I was the one who had beautiful connection while they had to deal with a load of d@ng. That said - I made a fresh install of Ubuntu 9.10. The problem got resolved and I was as happy as a chick during her first wedding night with Don Goivanni in her bed. BUT after I updated (note - update and NOT upgrade) my system, I was suddenly unable to use the wired connection. The strange thing is that the NM says that I am connected AND I even get some short bursts of network traffic (last for 2-3 seconds) but usually not enough to load even a simple web page. Ping always returns 100% loss no matter how long the package burst lasts. I have slept this night for about 3 hours looking for a solution. None has been found so far. I don't have WAPs at home so wired connection is the only way for me to use this modern thing called internet.
I'm having an issue with setting up the virtual hosts on my web server. I have 2 virtual hosts (example1.com, example2.com). example1.com works but example2.com is sent to the index file of example1.com. I did some searching on google and it seems the problem might be with my /etc/hosts file.
First virtual host that the second is also directed to...in sites-available/sites-enabled (note port 80 is blocked by my isp so I use 8080)
Code:
Second virtual host file
Code:
And my hosts file
Code:
# The following lines are desirable for IPv6 capable hosts
Also I'm using a dyndns.org...would that make a difference?
I've already gotten into the .mozilla folder and found the profiles.ini file. My windows XP system has it's Documents and Settings folder on a seperate drive (D:Documents and settings) And I've located the profile (application datamozillafirefoxprofiles) Now all I need to do is put the path into the profiles.ini file in the .mozilla folder in Ubuntu. The problem is I don't know exactly how to format it.
In windows the path is:
How would I translate this into something ubuntu "follows?" I already have the profile name changed as well.
I'm running Fedora 15 with current updates and kernel. I do not have anything special or non-standard about my configuration or setup. I use grsync to sync my home folder files to a remote rsync server on my network. I've checked my hard drives and my memory and everything else I can think. Here is the problem:
grsync will run for some time and once it nears completion it will crash. This, however, is no standard crash. It literally shuts my computer "OFF". I have shared the remote rsync folder through CIFS as well and I can copy those exact same files through nautilus with drag and drop without issue. I have had a few occasions where the rsync process will complete without issue, but this is a rare occasion. Since it powers my computer completely off I do not enjoy the luxury of having any log files or messages to attempt to diagnose from.
This is a small piece of code snippet I am pasting here.I have a hunch the memcpy is corrupting it. The platform is X86_64.Should I be doing a malloc on those variables inside memcpy and then use them in there?

I came home from my walk and my monitor was black, no activity when hitting keyboard or mouse. Shut down machine and then waited for reboot, it sticks to the same moment as picture posted. I tried dif boot seq in the selection but no luck. I cant find my boot disc.
Due to this problem, everything that uses python is not working.

I'm running Scientific Linux 5.5 (equivalent to CentOS 5.5), and over the past two weeks, I have had a problem with my root partition filling up, preventing anyone from logging into the server.After searching for large files, and finding none, I was mystified when du told me that the root partition had only 660 MB of disk space used, whilst df showed it full. The problem was this: the /var/crash directory had been filled up by an 8GB crash file. Now, I'm a 'proper' sysadmin and make sure that /var has its own mount point, so the crash should not have touched the root partition at all. Except it did - instead of writing to /var/crash on /dev/mapper/VolGroup00-LogVol04 which is mounted as /var, it wrote the file to /dev/md0 directly, so when all the file systems were mounted, those files were hidden under the mounted /var.
Every time I have Compiz activated and I try to watch a video full screen using VLC Player, or even Movie player, the player crashes. When I turn Compiz off, all is fine. How can I fix this?
I am on dual boot alongside windows 7 (which works fine). However, when I try to boot into linux I get a few minutes of the ubuntu icon. (sorry for lack of technical terminology). After a few minutes i get terminal sort of screen saying: fsck from util-linux-ng- 2.16 /dev/sda5: clean, 165561/625856 files, 984444/2502115 blocks I have attempted to boot from the live cd I installed from and there is no system response from it. How to either uninstall linux from here or just to get it to boot.
Since a couple of months, the machine is hanging itself. I can't connect in any way to it. I have it in a Datacenter far away my office, so when it happens I have to ask the provider to reboot it manually because it always happen in working hours and my clients gets mad on that moments. It happens every 15 days (more or less). It is very difficult to get the procesess status, but today hangs again and I could connect (a very very slow connection) and save a "ps aux".

There are some scripts that you can see as "php /var/www/html/call_engine.php ..." that are consuming CPU more than I expect and I will correct, but I would like to know about the other processes like many crond or the "/usr/sbin/sendmail -FCronDaemon -i -odi -oem -oi -t". Or maybe the whole problem would be the php script?
I have a gentoo distribution and need to store the information of dmesg collected until a system crash. At present, after a reboot or a crash the information in dmesg are lost and are not available at the next reboot. How can I save all the information in dmesg until a crash and read them after the succeed reboot?I also checked for dmesg.x files in /var/log or similar files but with no success.
I don't understand why, but my Slackware is totally crash after ~10min work. My guess is Nvidia is fault. Which logs I could see where the problem is? X (startx) work fine. My video card is: geforce 240. installed slackware 13.37 64 bit.
Code: #!/bin/bash ulimit -c unlimited while true; do ./executeable; done
When i will write this in console it will run executeable file and it will generate report : core.pid after crash so i can gdb the report. The application after crash will restart how can i prevent restarting the application after it's crash?
