  • Allow PHP to write file without 777

    - by camerongray
    I am setting up a simple website on webspace provided by my university. I do not have database access so I am storing all the data in a flat file. The issue I am experiencing is related to file permissions. I need PHP to be able to read and write the data file but I don't really want to set the file to 777 as anybody else on the system could modify it, they already have read access to everyone's web directories. Does anyone have any ideas on how to accomplish this? Thanks in advance

    - by user327958
    Lets say I have fields: name, number, id I have a data file: name1|number1|id1|name2|number2|id2...etc I want to replace every 3rd pipe with a new line or '\n' so I get: name1|number1|id1 name2|number2|id2 I'm having no luck with awk or sed.

  • Edit write-protected files by breaking hard links

    - by Taymon
    A directory which I own and can write to contains hard links to files that I don't own and don't have write permission for. I want to open and edit these files in Emacs. When I save my changes, Emacs should rename the existing hard link by appending ~, then write my new version of the file as a new file owned by me. I was under the impression that Emacs could just do this (because of the way it does backups), but it's not working; when I save, it attempts to change the file's permissions in order to write to it (and fails because I don't own the file). How do I make this happen?

  • Started an application through SSH, command line now gone, what happens next?

    - by Chris Dutrow
    Context: This is a very basic question Using Putty and SSH for the first time to do some serious server setup and run into the situation where I have started a process that I do not want to stop. The process is the gunicorn WSGI HTTP Server (running on Centos 6.3). The command I used to start the process is (as per their Quick Start): gunicorn -w 4 myapp:app At this point in the work session, I have lost the command prompt. This must be such a non-issue that it doesn't even enter into an experienced user's consciousness. But unfortunately at my level of experience, I am left with several fundamental questions: Does the fact that I have lost the command prompt mean that the process is still running? How do I get back to the command prompt without killing the process? How do I come back and monitor the process later? How do I eventually kill the process? Any help is appreciated, thanks so much!

  • USB webcam just works once and next time I've to reboot

    - by user30262
    I'm using Ubuntu 9.10, and a usb webcam that is shown as 'Bus 001 Device 005: ID 0ac8:3450 Z-Star Microelectronics Corp.' by lsusb. The problem is that on connecting the cam, it just works with the first program I start (skype, tokbox, messenger), and if I disconnect it or switch to another program, it stops to work and I have to restart my computer to make it work again. Has anyone else noticed this behaviour? Is there some good solution to reset the camera without rebooting to make it work again?

  • Xen HVM Windows 2008 network bridge

    - by JavierMartinz
    I have a problem with the Windows Server 2008 guest (hvm). I can't get a network interface running for him. I also have a Debian guest and it's working ok, but I can't do it with the Win2k8 guest. When I started the VM, the machine freezes and I can't connect by ssh to the host. /etc/network/interfaces # The loopback network interface auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 188.165.B.C netmask 255.255.255.0 network 188.165.B.0 broadcast 188.165.255.255 gateway 188.165.B.254 brctl show bridge name bridge id STP enabled interfaces eth0 8000.e840f20acc28 no peth0 /etc/xen/xend-config.sxp ... (vif-script vif-bridge) (network-script 'network-bridge') ... /etc/xen/win2k8.cfg # Networking # vif = [ 'ip=5.39.F.G,mac=yy:yy:yy:yy:yy:yy,type=ioemu,bridge=eth0' ] /etc/xen/debian.cfg # Networking # vif = [ 'ip=178.33.D.E,mac=xx:xx:xx:xx:xx:xx' ] As you can see, in the Debian guest I only have to specify an IP address and a MAC. But if I put that in the Win2k8 guest, the machine does not start. I am using Xen 4.0

  • Using Monit to monitor Resque

    - by Alex
    I'm trying to use resque as a job runner for Rails. I've tried this config, and many other ways of demonizing the rescue task (because running rake resque:work leaves the terminal tied to that command). Unfortunately, their example configuration doesn't work for me. Does the configuration look correct? Or is there another way to turn the process into a daemon? Thank you :) check process resque_worker_QUEUE with pidfile /data/APP_NAME/current/tmp/pids/resque_worker_QUEUE.pid start program = "/bin/sh -c 'cd /data/APP_NAME/current; RAILS_ENV=production QUEUE=queue_name VERBOSE=1 nohup rake environment resque:work& > log/resque_worker_QUEUE.log && echo $! > tmp/pids/resque_worker_QUEUE.pid'" as uid deploy and gid deploy stop program = "/bin/sh -c 'cd /data/APP_NAME/current && kill -s QUIT `cat tmp/pids/resque_worker_QUEUE.pid` && rm -f tmp/pids/resque_worker_QUEUE.pid; exit 0;'" if totalmem is greater than 300 MB for 10 cycles then restart # eating up memory?

  • Routing Traffic With OpenVPN

  • How do I tell which kernel module is servicing a /dev device?

    - by regulatre
    How do I find out which kernel module (as seen by typing lsmod) is servicing a particular device in /dev ? In other words, say I have a device, /dev/mouse0 and I want to find out which kernel module is installed to service that device. How do I do that? Another way to look at this is, some loaded kernel modules associate themselves with a device in /dev. How does one find out which device(s) a module is "attached" to?

  • Is Joerg Schilling’s “sdd” a full replacement for “dd”

    - by fishtoprecords
    I was directed to post here, I started on Stackoverflow.... I'm trying to use 'sdd' on my Debian system, and can't get one set of options to work. They do work in 'dd' so I am wondering if I am specifying them incorrectly, or if sdd didn't implement them, or something else. What I want to do is sdd if=/dev/hdh1 of=/bay5/imagebay1 bs=4096 conv=sync,noerror if I leave out the "conv=..." option, it works, or at least starts copying data. sdd if=/dev/hdh1 of=/bay5/imagebay1 bs=4096 Can you shed a bit of light?

  • Compiz and Desktop Effects on Netbook with External Monitor

    - by Nerdfest
    I have an Acer Aspire One AO150 and am having trouble plugging in an external monitor under Ubuntu 9.10. There were no problems under 9.04. If I plug in an external monitor once the machine is already up, then bring up the 'display' application to activate it, it basically hangs. There are no problem under these circumstances if I have desktop effects turned off. I've seen a few mentions of this problem on the Ubuntu forums, but never a solid solution. Any ideas? A few more details after a question below. The machine does not respond to its keyboard commands to switch to an external monitor, nor does it respond to Ctrl-Alt-F1, etc to switch out of X. The pointer is visible on the monitors (at the edge of each) and is frozen as a 'busy' cursor, but with no animation. The kernel does respond to SysReq commands (REISUB). In the latest attempt I had the external monitor active earlier, then removed it and activated desktop effects. Upon plugging in the eternal monitor then bringing up the display application, it hangs.

  • High system cpu load (%sys), system locks

    - by Mark
    For the last two weeks we are having intermittent severe spikes in system cpu usage (shown as %sys), which last for maybe half a minute, locking most processes, including ssh. I've been trying to figure this out, but atop doesn't show anything relevant (system usage for processes it shows is insignificant), spikes are intermittent and I could not reproduce the spike using any workload for the web application this webserver hosts. If you have any ideas on how to debug high %sys and (sometimes) %si CPU usage, please share them. System specs (don't know if any of this is relevant): Dedicated server, CentOS 6, core i7 950, consistent 4 to 8 GB RAM free at any time, hard drives are in RAID-1. Additional info: dmesg output doesn't change between spikes /var/log/messages doesn't change between spikes Here is cat /proc/vmstat Here is output of mpstat 1 during a typical spike Add 07.11.11: looks like simple reboot restored system state, and we might never know what caused the disturbance in first place.

  • Giving SSH access to a user, and security issues.

    - by Kris Sauquillo
    Okay, so I have a VPS and I made an account for a friend so he can host his own domains (using the reseller features in DirectAdmin). He's asking for SSH access, and I know that this is probably a bad idea. Does he have access to my whole server, such as executing commands, accessing my domains that I host on my server? I logged into my SSH using his account details and it let me navigate around all of the root folders/files, and his account is under /home/AccountName/. Is there anyway to restrict his access to his folder only? And the commands he can use?

  • Ubuntu Wired network(ethernet does not work)

    - by user36777
    It was working just fine, until the other day I yanked it out. The wireless works just fine on the same router. If I login to a windows 7 instance on this dual boot laptop then the ehternet works just fine. So it's not a hardware, cable or router issue. The card even gets an ip, but I can't connect to the internet. Here are the details from route, iptables, ifconfig, ping etc. Any ideas? I have been struggling with this for day, none seems to have an answer. http://pastie.org/954816

  • How can you get MySQL statistics for a specific user?

    - by Exit
    I've searched Google for a while on this and I'm not sure if it is easily or directly possible. I'm hosting a database on my cPanel server for a client which is accessed from their main website. As a result, I can't find a way to determine what amount of resources they are using. As there aren't any files under their account, cPanel reports the bandwidth at zero. I do know the stat programs don't monitor MySQL and that MySQL has a global statistics page that reports all usage on the server.

  • nfs mount fails in Ubuntu 10, but not with -v

    - by stuartreynolds
    (1) mount -t nfs remotehost:/remotedir localmountpoint -o owner,rw (2) mount -v -t nfs remotehost:/remotedir localmountpoint -o owner,rw (1) Used to work with Ubuntu 9 and now fails with Ubuntu 10 (2.6.32-21-generic kernel) with the error: mount.nfs: an incorrect mount option was specified Strangely, adding -v (verbose) in (2) makes the problem go away. This is currently a blocker for me because the fstab line: remotehost:/remotedir localmountpoint nfs owner,rw 0 0 causes the same error (I don't believe I can specify verbose in fstab). Is this a bug in mount or my options really incorrect?

  • Eject LiveCD + Reboot

    - by JPerkSter
    We use LiveCD's alot in my line of work. Whether it be fscking file systems, recovering data from a customer to rm'd his server, etc. I'm looking for a quick way to eject the CDROM and reboot the server. Does anyone have any one-liners to do this or any other suggestions? Using 'eject' doesn't work most of the time, from what I've tested / used. We're using RHEL / Cent on most of our servers if that helps :D

  • When should I upgrade to Ubuntu 10.04 (Lucid Lynx)? [closed]

    - by Emyr
    I'm a web developer for a small non-IT firm. When 9.10 came out, I was using it with no adverse effects from about a month before release (iirc, first beta), initially as an upgrade but as a clean install later to ensure my system would be consistent with most other 9.10 systems. The last alpha of 10.04 came out last week, with another 2 weeks before beta. I'm quite eager to do it today, but obviously the usual "not for production systems" notice is still in place. When should I upgrade? Do I need to worry about software installed from source? (./configure, make, make install etc) Is the attraction of a non-brown theme really this tempting for you?

  • How to get the CentOS 5.6 alsa drivers which will really work with one shot, without any internet.

    - by 89899.3K
    I have one chance to install this in my server on site. Server that i am running is CentOS 5.6 (Dell R310, RAID1) where i need to install alsa-sound driver so that anything related to audio recording from rtsp is working (rail station/rail passing video recording including audio, where audio is not working). Unfortunately i do not have any kind of internet in that odd none human location so yum will not work for me. I need a offline way to install alsa drivers including missing dependencies if arise. What and where i can download this to my usb or cd? so that i can successfully install it (like mission complete). Thanks

  • Avoid putty ssh terminal to crash when disconnecting from server

    - by JBoy
    I'm connecting via ssh to a remote 'live' server where i have some bash scripts automated via the crontab, when an error happens in some of the automation scripts within the server, the connection to the server is killed, this is fine to me, but the problem is that Putty closes the entire window, which is a behavior i don't want. I have checked all around the web, unfortunately the putty site does not have a support page, but nothing. Under putty's option i have tried all the menus expanding all options, but still i cant find the right one, i would expect it to be under Windowbehaviour Do you have an advice? Thx
