• LEMP Stack on Ubuntu Server 13.04 not parsing PHP Switch Statement Properly

  - by schester

  On my Ubuntu 12.04 Server LTS on nginx 1.1.19, the following PHP code works properly: switch($_SESSION['user']['permissions']) { case 9: echo "Super Admin Privileges"; break; case 0: echo "Operator Privileges"; break; case 1: echo "Line Leader Privileges"; break; case 2: echo "Supervisor Privileges"; break; case 3: echo "Engineer Privileges"; break; case 4: echo "Manager Privileges"; break; case 5: echo "Administrator Privileges"; break; default: echo "Operator Privileges"; } However, I have a backup server running Ubuntu Server 13.04 on nginx 1.4.1 which has the exact same copy of the script (synced) but instead of breaking on the break; command, it echos the whole php script. The output on the 12.04 Box is similar to this: You are logged in with Super Admin Privileges But on the 13.04 Box, the output is like this: You are logged in logged in with Super Admin Privileges"; break; case 0: echo "Operator Privileges"; break; case 1: echo "Line Leader Privileges"; break; case 2: echo "Supervisor Privileges"; break; case 3: echo "Engineer Privileges"; break; case 4: echo "Manager Privileges"; break; case 5: echo "Administrator Privileges"; break; default: echo "Operator Privileges"; } ?> I have also tried changing the script from switch statement to if statements but same results. Any idea what is wrong?

• MySQL replication/connection failing over SSL

  - by Marcel Tjandraatmadja

  I set up two MySQL servers where one is replicating from the other. They both work perfectly, but once I turn on SSL I get the following error: ERROR 2026 (HY000): SSL connection error I get the same error running from command line like so: mysql --ssl=1 --ssl-ca=/etc/mysql/certificates/ca-cert.pem --ssl-cert=/etc/mysql/certificates/client-cert.pem --ssl-key=/etc/mysql/certificates/client-key.pem --user=slave --password=slavepassword --host=master.url.com Both MySQL servers are running on version 5.0.77. There is a difference that MySQL in the master server was compiled under x86_64 while in the slave server under i686. Also both machines are running CentOS 5. Plus I generated certificates as per this page. Any idea for finding a solution?

• Why class 'SQLiteDatabase' is not found in /var/www/*.php?

  - by Roman

  I am trying to use sqlite from PHP. I have the following simple code: <?php $db = new SQLiteDatabase("test2.sdb"); unset($db); ?> As the result of this code (which I execute in the command line "php test2.php") I get: Fatal error: Class 'SQLiteDatabase' not found in /var/www/test2.php on line 3 Does anybody know how can I make PHP able to use sqlite? P.S. Here I found out that "SQLite support is enabled by default on a standard Linux PHP compilation starting with PHP 5.0." And I have "PHP Version = 5.2.6-2ubuntu4.6". So, sqlite should be enabled unless the "--disable-sqlite". In my case output of "phpinfo();" does not contain "sqlite" at all.

• My server is running out of memory, despite having all swap free

  - by Biohazard

  I am using Debian 6 (Squeeze). The server has 4gb of memory in it, and 8gb of swap. I'm starting to get memory alloc errors at high application load times, but from top command: Mem: 4055944k total, 3915436k used, 140508k free, 10444k buffers Swap: 7999480k total, 0k used, 7999480k free, 3604496k cached The system isn't even trying to use the swap? Why would this be happening? I would like to upgrade the primary memory, but this isn't possible just right now. Thanks.

• TrueCrypt with ext2/3 partition write access under Mac OS X Snow Leopard ?

  - by ssc

  I'm using a TrueCrypt volume with an ext3 partition under Snow Leopard with MacFUSE. I can mount ordinary (unencrypted) ext3 partitions read/write from the shell by adding command line arguments as shown in "Mounting ext3 in Snow Leopard…". However, TrueCrypt mounts the partition read-only and I don't see any way to 'sneak in' the required additional arguments. How do I mount it read/write? I was hoping for a similar solution as for mounting NTFS, but diskutil info /Volumes/my_volume/ does not return a UUID; it does tell me Read-Only Media: No Read-Only Volume: Yes though...

• Why do password entries over ssh take so long?

  - by Dean

  When I'm ssh'd into my server, any time I enter my password, there's a 40 second delay before the server responds. This occurs when logging in, as well as whenever I run a command via sudo. The delay does not happen when I run su and enter my password however. Using the -v flag for ssh doesn't show anything during this time. Looking at Wireshark, all traffic between the two machines stops while this is happening. Any idea what's happening, or advice on how to investigate this? The server is running Debian squeeze (6.0.4)

• In Puppet, how would I secure a password variable (in this case a MySQL password)?

  - by Beaming Mel-Bin

  I am using Puppet to provision MySQL with a parameterised class: class mysql::server( $password ) { package { 'mysql-server': ensure => installed } package { 'mysql': ensure => installed } service { 'mysqld': enable => true, ensure => running, require => Package['mysql-server'], } exec { 'set-mysql-password': unless => "mysqladmin -uroot -p$password status", path => ['/bin', '/usr/bin'], command => "mysqladmin -uroot password $password", require => Service['mysqld'], } } How can I protect $password? Currently, I removed the default world readable permission from the node definition file and explicitly gave puppet read permission via ACL. I'm assuming others have come across a similar situation so perhaps there's a better practice.

• How do I align my partition table properly?

  - by Jorge Castro

  I am in the process of building my first RAID5 array. I've used mdadm to create the following set up: root@bondigas:~# mdadm --detail /dev/md1 /dev/md1: Version : 00.90 Creation Time : Wed Oct 20 20:00:41 2010 Raid Level : raid5 Array Size : 5860543488 (5589.05 GiB 6001.20 GB) Used Dev Size : 1953514496 (1863.02 GiB 2000.40 GB) Raid Devices : 4 Total Devices : 4 Preferred Minor : 1 Persistence : Superblock is persistent Update Time : Wed Oct 20 20:13:48 2010 State : clean, degraded, recovering Active Devices : 3 Working Devices : 4 Failed Devices : 0 Spare Devices : 1 Layout : left-symmetric Chunk Size : 64K Rebuild Status : 1% complete UUID : f6dc829e:aa29b476:edd1ef19:85032322 (local to host bondigas) Events : 0.12 Number Major Minor RaidDevice State 0 8 16 0 active sync /dev/sdb 1 8 32 1 active sync /dev/sdc 2 8 48 2 active sync /dev/sdd 4 8 64 3 spare rebuilding /dev/sde While that's going I decided to format the beast with the following command: root@bondigas:~# mkfs.ext4 /dev/md1p1 mke2fs 1.41.11 (14-Mar-2010) /dev/md1p1 alignment is offset by 63488 bytes.

• HTTP Requests Fails for WordPress sites after upgrading from PHP 5.2 to PHP 5.3

  - by anjanesh

  I've upgraded from Ubuntu 9.10 to 10.04 beta 1 and PHP got upgraded from 5.2 to 5.3 Now all my WordPress & Magento sites arent working. I tried retrieving the URL headers from the command line, but HTTP request fails. Utilizing get_headers in a small script, PHP Warning: get_headers(http://local.vhosts1.com): failed to open stream: HTTP request failed! in get_headers.php on line 12 But HTTP request fails only for WordPress and Magento based sites - not custom written ones. Does this probably have to do with some htaccess directive ?

• Problem to connect to MySQL server (error #2002) in PHP

  - by Martin

  I installed ZWAMP 1.0.7 (on Windows 7), but I'm having a weird problem. I can't connect to my MySQL server from any PHP script. If I try to use MySQL command line everything works fine but PHPMyAdmin retruns error #2002. I'm not sure whether it's important or not but MySQL server is not able to create socket file. I don't know what's the problem but I think everything is configured in my.cnf properly. Do you have any ideas?

• sharepoint administrative server not started causing sharepoint deployment instability

  - by Nathan

  When i deploy anything to a variety of sharepoint servers i get problems with some packages failing, from what i can see the only error given is as below. The timer job for this operation has been created, but it will fail because the administrative service for this server is not enabled. If the timer job is sched uled to run at a later time, you can run the jobs all at once using stsadm.exe - o execadmsvcjobs. To avoid this problem in the future, enable the Windows ShareP oint Services administrative service, or run your operation through the STSADM.e xe command line utility. Is this a known problem? I googled for the text but got only one other person with the problem who simply worked round it. I'm trying to batch deploy solutions programmatically and so these errors render the whole code worthless if you have to go back and redo bits by hand afterwards. Is batch deployment simply not possible? Thanks!

• "sed" regex help: Replacing characters

  - by powerbar

  I want to change characters in a XML file by using sed. The input looks like this: <!-- Input --> <root> <tree foo="abcd" bar="abccdcd" /> <dontTouch foo="asd" bar="abc" /> </root> Now I want to change all c to X in the bar tag of the tree element. <!-- Output --> <root> <tree foo="abcd" bar="abXXdXd" /> <dontTouch foo="asd" bar="abc" /> </root> How is the correct sed command? Please consider, there can be more than one occurence of c (next to each other or not) in one tag... I tried this myself, but it won't change multiple c, and it does append a X :( sed -i 's/\(<tree.*bar=\".*\)c\(.*\"\/>\)/\1X\2/g' Input.xml

• Host is unreacheble with static networking configuration via /etc/network/interfaces while GUI NetworkManager is ok

  I have some trouble setting-up the network interface using the static IP configuration. I run ubuntu 12.04 kernel 3.11.0-22 with the back-ports enabled.

• How to get OpenSSH to use ksshaskpass under KDE?

  - by Guss

  When using a GNOME desktop on Ubuntu, if I use OpenSSH client to connect to another computer (running from the gnome-terminal), I get a single graphic popup asking for my private key's pass-phrase. After that I no longer need to enter my pass-phrase as it is cached by the SSH agent. Under KDE it doesn't work like that - when I start ssh from konsole, I get a text prompt for my pass-phrase every single time, even though ssh-agent is running. If I run ssh-add from the terminal then I can enter my pass-phrase on the terminal and it will be stored by ssh-agent and I won't get any more pass-phrase prompts, while if I run ssh-add the KRunner graphical command line ("Run" dialog) then I get a graphical prompt with the same behavior. The problem is I have to remember running ssh-add every time I log in to the desktop. How can I get ssh to behave under KDE, the same as it does on GNOME - the first time the pass-phrase is needed, pop up a graphical dialog and store the pass-phrase in the agent. I've installed ksshaskpass, but that didn't change anything.

• Proper way to let user enter password for a bash script using only the GUI (with the terminal hidden)

  - by MountainX

  I have made a bash script that uses kdialog exclusively for interacting with the user. It is launched from a ".desktop" file so the user never sees the terminal. It looks 100% like a GUI app (even though it is just a bash script). It runs in KDE only (Kubuntu 12.04). My only problem is handling password input securely and conveniently. I can't find a satisfactory solution. The script was designed to be run as a normal user and to prompt for the password when a sudo command is first needed. In this way, most commands, those not requiring sudo rights, are run as the normal user. What happens (when the script is run from the terminal) is that the user is prompted for their password once and the default sudo timeout allows the script to finish, including any additional sudo commands, without prompting the user again. This is how I want it to work when run behind the GUI too. The main problem is that using kdesudo to launch my script, which is the standard GUI way, means that the entire script is executed by the root user. So file ownerships get assigned to the root user, I can't rely upon ~/ in paths, and many other things are less than ideal. Running the entire script as the root user is just a very unsatisfactory solution and I think it is a bad practice. I appreciate any ideas for letting a user enter the sudo password just once via GUI while not running the whole script as root. Thanks.

• How can I load a file's contents into the clipboard?

  - by Jonathon Watney

  I have a files where I need to copy their contents to another file or into an application and rather than open it up, select all the text then copy and paste I'd like to know if I can effectively cat the file contents into the clipboard. Is this possible? A Windows program would be fine but something that works on Linux would be useful too. I don't use a Mac but it might be useful to others. Bonus points if this can be done on the command line.

• Run a batch file silently, executed at remote desktop login

  - by ILMV

  In our office we are using Linux thin client machines, they work very well except the lack of IE, which is a pain because the corporations we deal with are too stupid to update their web apps (no flame wars please). To solve this problem we have machine in our computer room which users remote desktop into to access internet explorer, this is achieved by running a batch script which opens IE and when it closes logs them off, this setup works well for us. Even though I have @echo off and the cmd window isn't displaying anything, I would really like that batch file to be executed silently, so the cmd window doesn't appear at all. Is this possible? The Ubuntu terminal server client has an option to launch a file / app at login, is there a command I can use to run this batch silently. I have tried these: C:\my_batch.bat /NOCONSOLE C:\my_batch.bat /NOWINDOW C:\my_batch.bat /B C:\my_batch.bat /Q ...with no success, perhaps it's the way I am doing it? Cheers :-) Edit The remote desktop platform is a Windows XP machine, nothing entirely special but not a Windows Server setup.

• Rails: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'

  - by misbehavens

  So I've got a Ruby on Rails application that I am trying to run (in development) on Snow Leopard. I've got it working on my Ubuntu computer, but now I need to get my Snow Leopard environment set up. Originally, I installed the MySQL 2.8.1 Ruby Gem and was running into this issue: uninitialized constant MysqlCompat::MysqlRes But thanks to this tutorial I was able to resolve it by running this command and installing a previous version of the Gem: export ARCHFLAGS="-arch i386 -arch x86_64" ;sudo gem install --no-rdoc --no-ri -v=2.7 mysql -- --with-mysql-dir=/usr/local/mysql --with-mysql-config=/usr/local/mysql/bin/mysql_config Now that I've resolved that issue, I'm running into a different error: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' This happens when I try to run rake db:migrate as well as when the server is running. How can I resolve this issue?

• bash : "set -e" and check if a user exists make script exit

  - by Dahmad Boutfounast

  i am writing a script to install a program with bash, i want to exit on error so i added "set -e" in the beginning of my script. the problem is that i have to check if a user exists inside of my script, to do this i am using "grep "^${USER}:" /etc/passwd", if the user exists, the script runs normally, but if the user doesn't exist, this command exists, and i don't want to exit on this case (i have to create the user and continue my installation). so what's the solution to make my script continue running ?? i tried to redirect the output of "grep" to a variable, but i still have the same problem :( thanks.
