  • I need to know the reasons why learning Linux Shell Scripting (BASH) benefits me as a PHP developer

    - by Ahmad Farouk
    I have been developing web sites/applications using the LAMP stack for almost 5 years. Currently I am interested to dig more into Linux OS, specifically BASH but from a web developer perspective, not from sys admin perspective. I am not intending to administrate Linux Servers. Only, I want to know, does learning shell scripting benefit me as a PHP developer? Does it make me a better, more skilled developer, or just its something irrelevant? Reasons, and examples are highly appreciated. Thanks in advance.

  • Randomly poor 2D performance in Linux Mint 11 when using nvidia driver

    - by SDD
    I am using: - Linux Mint 11 - Geforce 560ti - nVidia driver (installed via helper programm, not from nvidia page) The third party nvidia drivers radomly cause very poor 2D performance. Radomly because the performance can be very great, but after the next reboot or login become very poor. After another reboot or login, this might change again to better or worse. I have no idea why and how and I need your help. Thank you.

  • Networked filesystem with user level security for linux

    - by Konrads
    Hi, I want to enable file sharing between servers and clients, both linux. I don't want to rely on machine trust like in NFSv4 because client users will have root privileges. What are my options besides SMB (SAMBA)? Does OpenAFS support user level authentication & access? Using mounted WebDAV/ftp/sshfs seems silly for LAN.

  • No password mysql under linux?

    - by ripper234
    I was told that mysql user, similar to root user, by default "has no password". Not an empty password, but rather "no password". I wasn't aware this situation was possible - I thought every user on a linux had to have a password. Am I wrong? Can you point me to a link that explain this?

  • Linux-Mint Maya Mate loses Alt-F1 menu and Alt-F2 run-dialog with Compiz

    - by Peter.O
    I like the Linux-Mint 13 Mate Alt-F1 menu and the Alt-F2 run-dialog, but as soon as I installed Compiz those keys became non-functional. Conpiz has a Gnome compaatibility settings panel which allows you to set these keys, but using that Compix settings panel did not make any diference (probably because Mate is not Gnome, strictly speaking)... Is there some way to get those two shortcut keys back into acton with Compiz?

  • Avoid linux out-of-memory application teardown

    - by Eddie Parker
    I'm finding that on occasion my Linux box runs out of memory and it starts tearing down random processes to deal with it. I'm curious what administrators do to avoid this? Is the only real solution to up the amount of memory (will upping the swap alone help?), or is there better ways to set up the box with software to avoid this? (i.e., quotas, or some such?). I'd appreciate some feedback. Cheers, -e-

  • embedded php in html to include header (top part of page) into the page

    - by Andy
    Hi there, I'm trying to put the top of my page (which is all html) in a seperate file so I only need to change things once like the menu bar etc. So I googled some and found a solution on this website as well, but it doesn't work and I don't know why. So I have a page like article.html and on the top I have this: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html lang="en"> <head> <?php include("/pages/header.php"); ?> <!-- rest of the html code --> In the header.php I have the html that should be on the top of each page and it starts with: <?php /** * @author name * website header */ ?> <!-- html code --> So what's wrong with this. When I open the page article.html and right click on it to view the source, I can see the php from above calling the header.php file. Thanks!

  • Install virtualization software on a remote linux machine as a non-root user

    - by Cetin Sert
    Hi, 1) Is there a way for me to install VirtualBox as a non root user? I compiled it from the sources but cannot find a way to load the kernel modules it requires? Is there anyway to make it run? 2) Is there any other virtualization software you have ever installed on linux successfully as a non root user, VMWare, Parallels, etc.? The aim is to run Windows as a virtual machine with more than 16GB RAM. Bests, Cetin

  • Linux Fiber Channel Host Setup Basic

    - by Jim
    I've been googling for about 4 hours now with no luck. I am trying to setup a Linux server running Oracle Server 6.3 as a Fiber Channel host. And then connect it to a Dell Compellent Fibre Channel Host contain a 500GB Volume. The Oracle server itself contains two Brocade 815 FC HBAs. I've discovered their WWN(I think) via cat /sys/class/fc_host/host1/port_name 0x100000051efc3d85 cat /sys/class/fc_host/host2/port_name 0x100000051efc3d9f The next part is where I am at a loss. I've used iSCSI before...is FC the same deal where you have an initiator and a target? If so where do I specific that in linux? I'm also new to Fiber Channel as a protocol, so i am unsure what is needed to make a transaction? WWN and port ID? Similar to IP:Port combination in the Ethernet world. I've read alot regarding using systool, multipath, fc_transport commands, however none of these is recognized as a valid command from Oracle Server 6.3 Appreciate the guidance and assistance. I installed sccsi-target-utils and can now run rescan-scsi-bus and sg_map -x. rescan-scsi-bus.sh -l -w -r Host adapter 0 (megaraid_sas) found. Host adapter 1 ((null)) found.

  • App or apps like NetLimiter Monitor for Linux

    - by Nathaniel
    I find NetLimiter Monitor quite handy on Windows both for the realtime per-process bandwidth monitoring and the recorded data usage. What tool or tools can I use to replicate this functionality in Linux? I am okay using two separate apps for the bandwidth and the usage monitoring, but the usage monitoring is a must have.

  • How to change the sender of admin mails on a Linux server

    - by Cédric Girard
    Hi, I am sure it is a dumb question, but I want to change the sender of mails sended by my Linux server (centos 5). All mails sent to user "dev" are forwarded via a /home/dev/.forward file, with this sender : [email protected]. host.mydomain.fr is the hostname of this server, but it's an internal server and it does not even have a public IP. How to have a sender like [email protected]? I try to change the "official domain name" (line begining by "Dj" but it change nothing). Regards Cédric

  • Can Linux report IP conflicts?

    - by James
    If a Red Hat or other Linux host has a conflict with an IP address, is there a way to have it display a warning message on the console or in a log, like Windows and MacOS do? i.e. my computer has an IP address configured (or received from a DHCP server) but finds another device on the network using the assigned address. Will it log the conflict?
