  • Apache Custom Log Format

    - by Shishant
    Hello, I am trying to write a reward system wherein users will be given reward points if they download complete files, So what should be my log format. After searching alot this is what I understand its my first time and havent done custom logs before. First of all which file should I edit for custom logs because this thing I cant find. I am using ubuntu server with default apache, php5 and mysql installation # I use this commands and they work fine nano /etc/apache2/apache2.conf /etc/init.d/apache2 restart I think this is what I need to do for my purpose LogLevel notice LogFormat "%f %u %x %o" rewards CustomLog /var/www/logs/rewards_log rewards This is as it is command or there is something missing? and is there any particular location where I need to add this? and one more thing %o is for filesize that was sent and is it possible to log only files from a particular directory? or for files with size more than 10mb. Thank You.

  • Can org.freedesktop.Notifications.CloseNotification(uint id) be triggered and invoked via DBus?

    - by george rowell
    ref: Close button on notify-osd? Bookmark: Can org.freedesktop.Notifications.CloseNotification(uint id) be triggered and invoked via DBus? Currently, this script dbus-monitor "interface='org.freedesktop.Notifications'" | \ grep --line-buffered "member=Notify" | \ sed -u -e 's/.*/killall notify-osd/g' | \ bash will kill all pending notifications. It would be better to finesse the specific target OSD notification to cancel, by using org.freedesktop.Notifications.CloseNotification(uint id). Is there an interface method that can put this on (in?) the DBus to fire when a particular notify event occurs? The method will need to get the notify PID to use as the argument for CloseNotification(uint id). Alternatively, qdbus org.freedesktop.Notifications \ /org/freedesktop/Notifications \ org.freedesktop.Notifications.CloseNotification(uint id) could be used from the shell, if the (uint id) argument could be determined. The actual command syntax would use an integer in place of (uint id). Perhaps a better question to ask first might be "How is the DBus address for a notification found?". In hindsight the previous question "How is the (uint id) for a notification found?" is rhetorical! This previous answer: http://askubuntu.com/a/186311/89468 provided details so either method below can be used: gdbus call --session --dest org.freedesktop.DBus \ --object-path / \ --method org.freedesktop.DBus.GetConnectionUnixProcessID :1.16 returning: (uint32 8957,) or qdbus --literal --session org.freedesktop.DBus / \ org.freedesktop.DBus.GetConnectionUnixProcessID :1.16 returning: 8957

  • monitoring load on AWS EC2

    - by hortitude
    I'm interesting in monitoring our EC2 instances to ensure we scale up when necessary. Right now we are monitoring idle CPU time as our metric. We aren't measuring disk IO as we are not a very disk intensive application. When running on our own hardware in a datacenter I also usually monitor "load" from the top command. My question is: Does it make sense to monitor "load" on a shared env such as EC2? If so, how do you interpret the results?

  • Ubuntu 13.10 Unity doesn't load after upgrade

    - by William
    Just upgraded to Ubuntu 13.10 only to find that Unity won't load (login freezes, after doing ctrl+alt+F1, logging in and then doing startx, I get a blank desktop and the mouse pointer, and nothing else). I can right click, but the only operations that work are "create new file" and "create new folder". For example, "change desktop background" doesn't work. Also, after doing a few right clicks and choosing "change desktop background", I get a warning message box: "compiz closed unexpectedly." Guest login works fine. Tried creating a new user, but I experience the same thing with the new user. Tried removing all configuration files from my home directory... same thing. Doing dconf reset -f /org/compiz/ gives an error "error spawning command line..." Doing unity --reset also gives errors. Tried uninstalling unity (and compiz) and reinstalling, but that doesn't help. Tried reconfiguring lightdm, didn't help. I don't have any proprietary drivers installed. Once again, the funny thing is that the guest session works fine.

  • Oh snap! My RPi was upgraded to 512MB! Woo-hoo!

    - by hinkmond
    I ordered a Raspberry Pi Model B (256MB) over 4 months ago on backorder. When it finally came I saw it was upgraded to the new half a gig model! Woot! But, all was not perfect. Gary C. told me the shipped configuration of the new RPi models didn't have the right firmware for 512MB, and I had to upgrade the start.elf in the /boot directory to recognize all of the 512MB RAM. I did a "free" command, and sure enough saw only 240MB. Sadness. But, Gary gave me a copy of his start.elf which worked after some trail and error. For anyone ordering the new RPi Model B w/512MB, here are the steps to get you going with full 512MB RAM: sudo apt-get update --fix-missing sudo apt-get upgrade --fix-missing # NOTE: This step takes at least a couple hours on a # fast network wget https://raw.github.com/raspberrypi/firmware/\ 164b0fe2b3b56081c7510df93bc1440aebe45f7e/boot/\ arm496_start.elf sudo mv /boot/start.elf /boot/orig-start.elf sudo mv arm496_start.elf /boot/start.elf sudo reboot free total used free shared buffers cached Mem: 497768 210596 287172 0 16892 169624 -/+ buffers/cache: 24080 473688 Swap: 102396 0 102396 So of course this means... (drumroll) there is now 498MB available for the Java Embedded heap! java -Xmx400m -version java version "1.7.0_06" Java(TM) SE Embedded Runtime Environment (build 1.7.0_06-b24, headless) Java HotSpot(TM) Embedded Client VM (build 23.2-b09, mixed mode) Yeah, baby!

  • Entire filesystem restore from rdiff-backup snapshot

    - by atmosx
    I'm trying to make a complete system restore from an rdiff-backup. The cli for backing was: rdiff-backup --exclude-special-files --exclude /tmp --exclude /mnt --exclude /proc --exclude /sys / /mnt/backup/ebox/ I created a new partition mounted the partition at /mnt/gentoo and did: rdiff-backup -r /mnt/vol2 /mnt/gentoo However when I try to chroot to this system (following gentoo's manual, which means mounting /dev/ and /proc) I get the following error: chroot: failed to run command/bin/bash': No such file or directory` All this takes place on a Parallels (virtual machine) Debian installation. Any ideas on how to proceed in order to fully restore the system? Best Regards ps. /mnt/gentoo/bin/bash works fine if I execute it. All files and permissions are in place rdiff-backup seems to work just fine. However the system cannot neither boot (exits with kernel panic - cannot find init) or be chrooted.

  • after install python 2.7.3 yum is broken

    - by user468587
    i installed libxml2-2.9.0 and libxslt-1.1.27 then yum is broken any yum command that i ran i got the result of : There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: No module named yum Please install a package which provides this module, or verify that the module is installed correctly. It's possible that the above module doesn't match the current version of Python, which is: 2.4.3 (#1, Jan 21 2009, 01:11:33) [GCC 4.1.2 20071124 (Red Hat 4.1.2-42)] If you cannot solve this problem yourself, please go to the yum faq at: http://yum.baseurl.org/wiki/Faq then i thought python version is way too old and install python 2.7.3 and install it from scratch, after some wrong trials it got worse and worse, now when i run 'python -V' i got version 'Python 2.7.3', when i run '/usr/bin/python -V', it returned 'python-2.4.3-24.el5', and no matter what i did the yum is still broken with that message. how can i get yum back? my os is: linux 2.6.18-164.11.1.el5 x86_64 GNU/Linux

  • Apache CPU usage stays at 100% even when there are no requests

    - by Leirith
    Hi, I've been running the Apache HTTP server benchmarking tool (ab) on my new Apache server to test performance. I noticed that with a command like the following: ab -n 100000 -c 1000 http://www.mysite.com/ The CPU is used 100% by the apache2 processes during the testing. When the test concludes, usually with the following error just before the last requests are made: apr_poll: The timeout specified has expired (70007) Total of 99960 requests completed the CPU usage remains at 100%, and it's all being consumed by apache. I am using the worker MPM with and running PHP with mod_fcgid. Any advice as to why this is or what can be done to stop it would be appreciated.

  • Dir and Findstr commands taking a long time to complete in Batch File

    - by user2405934
    dir %DRIVE_NAME%: /S /C /A-D /Q /T:C | findstr ".zip$ .doc$ .xls$ .xpt$ .cpt$ .cpo$ .xlsx$ .pdf$ .dat$ .txt$ .docx$ .csv$" >> file.info I am using above command to list all information in file, as below: 03/27/2013 01:02 PM 86,280 uusr\fr02 h123_frf67_rk_20140327.txt 03/27/2013 01:02 PM 5,513 usr\fr02 h123_frf67_rk_20140328.txt %DRIVE_NAME%: is mapped drive. Folders will be the same; not more than 100 folders and their sub-folders, and there will only be 2 or 3 files at time in any one of the folders. Now the issues is that for one folder it works perfect, but for 80 to 90 folders it is taking too much time. I think it's because of findstr and the different extensions used. Is there any way to make it faster?

  • Compiz: How can I pin osd-lyrics to the Desktop?

    - by joebuntu
    Hey ya, I have certain applications pinned to my desktop. such as Rainlendar (1), which offers this option in the settings window conky (2), with "own_window_type normal" in my ~/.conkyrc Rhythmbox's Desktop Cover Art plugin (3), a python plugin sticked to the desktop. They all hide nicely below all other Windows. I set Compiz to not minimize them on "show desktop" command using "window rules". I also use [osd-lyrics][1] to display music lyrics. It's default behaviour is to stick always on top, which is irritating sometimes and, in my case, looks rather fugly. (4) See screenshot at: http://i.imgur.com/ie16K.jpg Now how can I tell Compiz to pin the osd-lyrics bar to the desktop below all other windows and not minimize it? I tried all sorts of window rules and exceptions, e.g. using "class=osd-lyrics", "title=osd-lyrics" but the OSD doesn't seem to match any of these. Any ideas? Running: Ubuntu 10.10 Maverick Meerkat, Compiz 0.8.6, osd-lyrics 0.3 from code.google.com/p/osd-lyrics

  • How do Unity 12.04/Compiz bindings really work?

    - by Daniel
    There is a bewildering array of places to set bindings, all inconsistent with one another. E.g. in Unity's System Settings having the Ctrl-key highlight the mouse position is an on/off choice. I like the feature, but not on such a prominent key where I keep activating it accidentally. The keyboard shortcuts allow only one binding per command, where I might like a convenient one on the external keyboard and an emergency alternative for when I'm on the road. Keyboard custom shortcuts has a nice interface, but allows only key bindings — besides it doesn't seem to work for me. So I activated CCSM Commands. There I have the choice of key-, mouse- and/or edge bindings. Whereas some places in CCSM offers only one or two of these binding possibilities, randomly at the whim of the programmer. I have not found a way to differentiate a mouse-drag from a click. E.g. I want <SuperMouse1-drag anywhere on a window to move it, while if I don't drag, it should be raise-lower. On the title bar I want the same without needing the <Super key. Now I find raise-lower only in System Settings where I can't assign a mouse binding. If therefore in CCSM I fallback to only lower and put move on the same binding, the window already gets lowered on mouse down, and I can then invisibly move it. Very useful! I have <Altasciicircum get in the way of an Emacs binding, with some to me useless popup overlay. I can find it nowhere, so I can't turn it off. So how can I go without these frontends until they have matured, and instruct Compiz directly, for example in the way Emacs or Sawfish have keymaps, and separate ones for each context, with inheritance?

  • How can I resolve this error when using net start / stop: "The service name is invalid" ?

    - by JosephStyons
    We have a server that hosts a service (I'll call it "tomato"). Up until now, a client pc has been able to start and stop this service. They just double-click a batch file, and inside that batch file is the command net stop tomato or net start tomato They recently got a new physical computer, and now those same commands fail with the error: C:\>net stop tomato The service name is invalid. More help is available by typing NET HELPMSG 2185. What do I need to do to let the client pc start and stop this service remotely? Edit: I mis-remembered the original commands. They were not using "net start" and "net stop" remotely. They were using sc \\server_name start tomato and sc \\server_name stop tomato And those commands to indeed still work.

  • Cannot write, format, nor erase flash drive

    - by Baruch
    I have a 4gig flash drive, which I can read from but not write on, erase, nor format in any computer (tried in 7 different computers including xp, vista, and win7). I want to erase all the data inside because it is useless. Once I erase something, it erases it and gives me an error that it can't find the file. Once I refresh the folder, the file comes back. I tried holding Shift + Del. I also tried to use the command to format it in safe mode, but it says "access denied". I don't have a write protection button or whatever it is on my flash drive. It's just a simple small 4 gig one.

  • How do I check to see if an apt lock file is locked?

    - by gondoi
    I am writing a script to do some apt commands, but I am running into potential issues of the apt/dpkg databases being locked so my script bails. I want to check the lock files (i.e. /var/lib/dpkg/lock) before doing anything just like apt does when it runs it's command, but I can't figure out how apt is performing the lock. The lock file is always there, and apt-get is not doing a flock on the file. How else would it be checking to see if it is in use? From an strace I see that apt-get opens the file, but that is it. In my script, I can open the file while apt-get has it open as well.

  • dvcs - is "clone to branch" a common workflow?

    - by Tesserex
    I was recently discussing dvcs with a coworker, because our office is beginning to consider switching from TFS (we're a MS shop). In the process, I got very confused because he said that although he uses Mercurial, he hadn't heard of a "branch" or "checkout" command, and these terms were unfamiliar to him. After wondering how it was possible that he didn't know about them and explaining how dvcs branches work "in place" on your local files, he was quite confused. He explained that, similar to how TFS works, when he wants to create a "branch" he does it by cloning, so he has an entire copy of his repo. This seemed really strange to me, but the benefit, which I have to concede, is that you can look at or work on two branches simultaneously because the files are separate. In searching this site to see if this has been asked before I saw a comment that many online resources promote this "clone to branch" methodology, to the poster's dismay. Is this actually common in the dvcs community? And what are some of the pros and cons of going this way? I would never do it since I have no need to see multiple branches at once, switching is fast, and I don't need all the clones filling up my disk.

  • mysql error code 13 on windows xampp caused by lower case table names = 0

    - by user127379
    I can import an sql (from test linux server mysql) file if the lower case setting is removed. But then the table names are lower case and the web site doesn't work. Originally it was working (my.ini with the lower case settings), I then exported to a linux server, it was working there. Now importing back to my windows (xampp setup) fails. After wild goose chase looking at disks and permissions, I found that if I remove the lower_case_table_names=0, the import works! But I need the case sensitive command so that I can deploy on the linux server.

  • Concatenate two mp4 videos into one file

    - by Jer
    I recently ripped my DVD collection to play them on my media center PC, and several of them are two-disc movies (i.e. The Lord of the Rings). Since I ripped each DVD individually, that gives me two video files for some movies. I am using Ubuntu Linux - how can I concatenate these two MP4/H.264 videos into a single MP4 video file? Preferably from the command line, and without re-encoding everything during the process (although I can try figuring out a video editor like Pitivi if that's the only solution.)

  • Setup IPv6 over IPv4 tunnel in VPN

    - by bfmeb
    Let me explain my szenario: I have a linux server A. A is reachable in a VPN. So if I am connected to the VPN over Internet I can successfully ping A. Server A is connected to a Router B. Router B has a local ipv6 address and there are resources (each of them with a local ipv6 address) connected to Router B. After I am connected to VPN, I am able to use ssh to have access over A. Now I can use the ping6 command to ping the Router B or one of its connected resources. This works fine. The ping fails if I try to ping router B on my computer. Overview: My Computer -- VPN -- Server A(ipv4) -- Router B(ipv6) -- Ressource A(ipv6) On resource A runs for example a HTTP-Server. My question is: How can I access Resource A (for example with HTTP) on my to VPN connected computer? Is it possible? Should I setup a tunnel device? Sorry for this inexpertly explanation, but I am new to network stuff!

  • Using mongodump with an auth enabled mongodb server

    - by bb-generation
    I'm trying to do a daily backup of my mongodb server (auth enabled) using the mongodump tool. mongodump provides two parameters to set the credentials: -u [ --username ] arg username -p [ --password ] arg password Unfortunately they don't provide any parameter to read the password from stdin. Therefore everytime I run this command, everyone on the server can read the password (e.g. by using ps aux). The only workaround I have found is stopping the database and directly accessing the database files using the --dbpath parameter. Is there any other solution which allows me to backup the mongodb database without stopping the server and without "publishing" my password? I am using Debian squeeze 6.0.5 amd64 with mongodb 1.4.4-3.
