I don't remember exactly when I have installed rEFIt (I did it only once) but I know I am using it without any problems since around 2006 and it went trough 2 laptops and several OSX versions already. The beauty of OSX upgrades and Time Machine.
After installing El Capitan, I was still using it without problems (well, just a small one but no biggie - will be mentioned a bit later), but also with SIP enabled! Will explain about SIP too.
Launchd is designed to start System and Users daemon/agents located in the following places:
~/Library/LaunchAgents - Per-user agents provided by the user /Library/LaunchAgents - Per-user agents provided by the administrator /Library/LaunchDaemons - System-wide daemons provided by the administrator /System/Library/LaunchAgents - Per-user agents provided by Mac OS X /System/Library/LaunchDaemons - System wide daemons provided by MAC OS X
You have a bunch of applications designed to show you temperatures and fan speeds in graphical environment. Some are free but most of them are paid.
But what happens if you need something in command line? Well, it is even better because you can find many free powerful tools.
One of them is iStats. Below you will learn how to install and use it.
Prior to OS X 10.10 Yosemite, you were able to start rc.local script via rc..
That is gone and you have to use launchd.
This tutorial assumes you have already your rc.local script in (example) /etc/rc.local and it is executable and properly populated with your desired commands.
So, without writing too much, below is my example of launchd script:
You use finger command in order to check user information. What if it's missing?
The official replacement for the original finger command and it’s part of the gnu coreutils package, it is called pinky and it’s available on all systems that use the gnu coreutils.
For this example I will user md5 but in similar way you can use whatever you want in order to create a hash version of your text password.
As a security note, I do not recommend using md5 to generate hash passwords because today it is very easily broken. This is jut a proof of concept.
I got this SMF forum for my wife and is working very well. I am very satisfied with SMF.
However, sometimes you get into trouble with it and the worst part is you do not have much logs to work with. Also, apache logs won't help much either.
You are here because you got this error when trying to run php via command line: PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20100525/pdo_mysql.so' - /usr/lib/php5/20100525/pdo_mysql.so: undefined symbol: pdo_parse_params in Unknown on line 0
Also, you probably use Debian Squeeze and you recently did software update.
If yes, read on for a fix.
AIO subsystems in 6.1 and later are loaded by default and not activated. It is implemented as kernel service instead of using special device aio0 as in previous AIX versions. The kernel module tuning (maxservers, minservers, etc.) is implemented via ioo command.
In order to check the available aio tunables, you must use the following command: # ioo -L | grep aio
The moment application initiates the AIO I/O requests, the subsystems are automatically started.
Your zfs was working properly but you have upgraded your system, including the kernel, and your zfs is no more available.
This is normal because zfs was compiled for the other one.
So all you will have to do is to execute the following commands (do not forget of course to install/put in place the needed linux source or headers before that): dpkg-reconfigure spl-dkms dpkg-reconfigure zfs-dkms
If you do not know what Centrify is, most probably you do not need the commands below. However if you are curious, more info can be found on their website: http://www.centrify.com
In a nut shell, Centrify allows UNIX/Linux/OSX machines to join Active Directory. In Centrify enabled environment, you will have only one AD account to connect on all systems, no matter the platform (Windows, Linux, AIX, Solaris, HP-UX, Mac OS X, etc.).
Most common place to get this error is when you try to compile something in cygwin environment because the configuration script is not able to detect properly the system type due to missing important information in config.guess. Therefore, in order to make it work, you need to replace the file with the one available in your system, providing you have installed already automake package.
In Debian, the proper way to configure vlans, after you install the vlan software, is to populate the configuration file /etc/network/interfaces. Of course, you can create them also with vconfig command. Examples after the debian way.
TCP offload engine or TOE is a technology used in network interface cards (NIC) to offload processing of the entire TCP/IP stack to the network controller. It is primarily used with high-speed network interfaces, such as gigabit Ethernet and 10 Gigabit Ethernet, where processing overhead of the network stack becomes significant.
In this tutorial, I will explain how to replace the drbd backend devices (for data and metadata) without destroying the information. Actually, during this process, the information will be safely kept on the other node.
This should be done in case of one node's disk failure or if you simply just want to move the date to other disk.
