I plan to create my first DC and forest on a physical server, then I want to run a second DC on a virtual server that will replicate the first DC. I understand that this will provide redundancy for AD that if the first domain controller went down the second would resume until the first is back online. Would this work and how?
I have a pair of x25-M 160 Intel SSD's in an HP DL360 G5 with a p400i Smart Array running 512 BBWC. The disk performance I am getting on this box and another identical one does not come close to matching the same two drives running through a cheap 3ware RAID card. Any idea?
I have played with the cache settings, but nothing allows me to get the same results. It seems like the Smart Array controller is the bottleneck.
I'm playing around with virtual disks and thin provisioning and have a question about it.
I've created several disks and allocated space to with thin provisioning. Is it possible to allocate more disk space than the maximum amount of the datastore space. So that for example, my VM's will stop functioning when the disks slowly start filling up?
I have all my domains parked with Godaddy registrar, and now I have aquired a small dedicated server to migrate all my sites.
How do I park my domains in the new site?
The server is a Red Hat Enterprise Linux Box with Apache and Nginx running.
The only way to access the server right now it's via IP address.
I have a FreeBSD 8.0 amd64 box w/ 1 ATA drive for system and 4 SATA drives as a RAIDZ pool. The ATA drive isn't mirrored nor part of any pool, but also doesn't hold any valuable data.
How can I recover my zpool if this ATA drive fails for any reason, but assume my RAIDZ vdev SATA drives remain intact? Should I also use at least a mirror configuration for that?
We use Apache 2.2 to host SVN repository on a Windows 2003 machine.
Works fine except that over a couple of weeks the httpd process inflates and starts consuming something like 1.5 gigabytes of virtual memory. All operations with the repository become very slow.
What to tweak to prevent httpd from cosuming so many resources?
We are using OpenNMS to monitor a pool of servers, and we have a problem with SMTP in one particular box. OpenNMS is "spamming" us all the time with DOWN/RESOLVED messages for that particular service in that server, and I wanted to mute those notifications momentarely but couldn't find how to do that. I know that I can disable ALL notifications or disable SMTP in ALL servers, but that's not what I want.
I'm used to muting a particular service in Nagios, but is it possible in OpenNMS?
Two question regarding sudo-login into an ubuntu-system (debian tips welcome as well):
Is it possible to require sudoers on my box to only login with publickey-authentication?
Is it possible to log which ip sudoers log in from and check that for "unusual activity" or take actions? I'm thinking about temporarily removing sudo-rights if sudoers don't log in from whitelisted IPs. Or is that too risky to be exploited?
I have a Debian VPS with an assigned static IP. I want to setup a virtual interface (with an ip like 192.168..) on my laptop (Ubuntu, dynamic IP) linked to the remote VPS, so that if I bind sockets to it the traffic is tunneled to the VPS and sent to the Internet from there. Port forwarding must be available.
This looks like a job for a VPN software, but I'm clueless about the pieces of software needed. Any advice?
I set up a local server without MAMP, for various reasons. I used this tutorial: http://coolestguyplanettech.com/downtown/install-and-configure-apache-mysql-php-and-phpmyadmin-osx-108-mountain-lion
I'm just wondering why the local IP and localhost resolve to two different locations. Right now the IP resolves to a Virtual Host I set up and the localhost resolves to the DocumentRoot established by httpd.conf
When opening a new monitor I am amazed that the VGA cable is always attached. Even with new high end monitors that include Display Port and DVI cables the old VGA cable is always attached while the others are just left in the box.
What is the reasoning behind attaching a cable in the first place and why the VGA cable in particular?
I have an OS X box running iTunes on it. I play music with iTunes connected to an Apple TV. In iTunes I can select Apple TV as the output sound device. Am I able to do that with any other application? Apple TV does not show up as a seperate device in System Preferences. I'd like to browse and play YouTube videos in my computer and stream their sound to Apple TV.
Is it better to run a VM on a dual core hyperthreaded machine as a four core or as a two core VM.
The hyperthreaded 'virtual' cores are not as fast as the real cores. Does this effect the VM?
I have the 'Safely Remove Hardware' tray icon set to 'Show icon and notifications' to save a mouse click when removing a USB device but every few weeks the setting reverts to 'Only show notifications'. Does anyone know what causes this and/or how I can prevent it?
I'm using Windows 7 SP1 64bit with a fairly bare installation (the machine hosts a set of virtual machines that I use to do my work).
Thanks!
I received a out of memory error
SQL Error: 0, SQLState: 53200
from postgres while trying to upload a 10MB file into a single row with a column of blob-type bytea.
Which configuration parameters should be changed to allow inserts of this size, or should this work out of the box without modifications?
Is there an option like in informix-db to create so called blob-spaces?
I am trying to do the following on my Mac (10.6.7) :
sudo chown myusername:wheel ./entries
but Unix/Mac is returning "Operation not permitted". When I ls -lash, the culprit file, it looks as follows:
8 -rwxrwxrwx 1 myusername staff 394B Apr 26 23:26 entries
I've tried sudo, I've tried sudo su, nothing works? Any ideas what's up?
The files I'm trying to chmod I've copied from my old Ubuntu box, most of the files have successfully chmodded recursively, just this one is stuck and I don't understand why.
looking to build a box for holding 5 to 8 TB of storage using nexentastor OS. without using commercial solutions like netapp.
my current list is:
Intel Xeon
8GB of RAM
RAID controller with 256MB cache
what to choose for disks? can any sigle server host more than 5TB disks? Dell Poweredge? HP DL or ML Series?
O.K I am trying to do the following very simple command and it is failing as follows...
mv '/home/admin/Downloads/folder1' '/home/admin/MyLibrary/MyVideos/TV/folder1/'
mv: cannot move `/home/admin/Downloads/folder1' to a subdirectory of itself, `/home/admin/MyLibrary/MyVideos/TV/folder1/'
The destination is NOT a subfolder of the source - why is it giving me this error??
Linux version is a custom version of Red Hat on a NAS box. Thanks
I have a fully working Joomla 2.5.6 install driven by a local MySQL server, but I'd like to test nginx to see if it's a faster web serving experience than Apache.
\ PHP 5.4.6 (PHP54w)
\ CentOS 6.2
\ Joomla 2.5.6
\ PHP54w-fpm.i386 (FastCGI process manager)
\ php -m shows: mysql & mysqli modules loaded
Nginx seems to have installed fine via yum, it can process a PHP-info file via FastCGI perfectly OK (http://37.128.190.241/php.php) but when I stop Apache, start nginx instead and visit my site I get: "Database connection error (1): The MySQL adapter 'mysqli' is not available."
I've tried adjusting my Joomla configuration.php to use mysql instead of mysqli but I get the same basic error, only this time "Database connection error (1): The MySQL adapter 'mysql' is not available" of course!
Can anyone think what the problem might be please? I did try explicitly setting extension = mysqli.so and extension = mysql.so in my php.ini to try and force the issue (despite php -m showing they were both successfully loaded anyway) - no difference.
I have a pretty standard nginx default.conf:

Snip of output from phpinfo under nginx:
Server API FPM/FastCGI
Virtual Directory Support disabled
Configuration File (php.ini) Path /etc
Loaded Configuration File /etc/php.ini
Scan this dir for additional .ini files /etc/php.d

Snip of output from phpinfo under Apache:
Server API Apache 2.0 Handler
Virtual Directory Support disabled
Configuration File (php.ini) Path /etc
Loaded Configuration File /etc/php.ini
Scan this dir for additional .ini files /etc/php.d
Additional .ini files parsed /etc/php.d/curl.ini, /etc/php.d/fileinfo.ini, /etc/php.d/json.ini, /etc/php.d/mysql.ini, /etc/php.d/mysqli.ini, /etc/php.d/pdo.ini, /etc/php.d/pdo_mysql.ini, /etc/php.d/pdo_sqlite.ini, /etc/php.d/phar.ini, /etc/php.d/sqlite3.ini, /etc/php.d/zip.ini
Seems that with Apache, PHP is loading substantially more additional .ini files, including ones relating to mysql (mysql.ini, mysqli.ini, pdo_mysql.ini) than nginx.
Any ideas how I get nginix to also call these additional .ini's ?
Thanks in advance,
Steve
I have a postfix + virtual users setup. I have enabled maildrop as the delivery agent. How can I write a filter for a user so that if mail comes from a particular domain to that user a copy also goes to another email address.
I'm using Windows XP and Internet Explorer 8, and occasionally one off my favorites (Link) folders will get a very small box in the upper right corner (on the favorites menu drop down itself) and not open at all. I can't figure out how it got there or how to disable it, and I have to completely shut IE down and restart it to get rid of it.
Any clues on what's going on?
I'm certainly trying to achieve something weird here, but I want to fake the date locally for a shell session on GNU/Linux.
I need to black-box test how a program behaves at different dates, and modifying the system-wide date can have unwanted side effects (cron jobs, messed up logs, etc).
Any ideas ?
Postfix serves for my virtual domains and works fine.
But for one of my domains:
- it bounces mails targeted at [email protected]
- it rejects mails targeted at [email protected]
problem is, [email protected] does not exist either.
here is my postconf
why does it bounce [email protected], and reject other non existing mails?
Thanks.
My text and programmers editor of choice, when working on a windows box is TSE (The Semware Editor). It is small, it is fast, it is configurabel, and since I've used it (and it's predecessor QEdit) for over twenty years, my fingers can do the editing on autopilot, while the brain is busy with syntax and design.
Do you know of a similar editor preferably one that runs on Windows, Linux and OS X (and Solaris ..)
I've tried to use VIM (I know how to use VI even longer thant TSE) but it doesn't feel right.
