I have a MySQL instance containing a number of databases, one of which is an archive database (although using the INNODB rather than ARCHIVE storage engine) that is not queried or written to in normal operation.
The data filesystem is filling up and I'd like to move the archive database's data directory to a different filesystem (and then symlink…
I am playing around with transparent proxies, The current way I am doing things is the program makes a request to a computer on port 80, I use
iptables -t nat -A OUTPUT -p tcp --destination-port 80 -j REDIRECT --to-port 1234
to redirect to my proxy that I am playing with. the proxy will send out a request to port 81 (as all outbound port 80…
I've restored a database which came from a server on which Slony was running. The server on which the database has been restored does not have Slony installed.
When the database restored, there were a lot of errors reported, with Slony related objects not getting created due to Slony related logins being missing. This I thought was not a…
I've heard that the write performance of RAID 5 can be appalling at times. While I want the redundancy that it provides I don't want to sacrifice my database insert/update times.
Is this something I should be worried about and if so, what would be the recommendation to get redundancy with good write performance?
I finally convinced upper management that we need a computer replacement plan, and I've been tasked with making an inventory of what we have and determining what needs to be replaced this year, next year, the year after, etc. I had to use some sort of criteria to back up my recommendations, so I decided to try using the Windows Experience…
We are about to deploy a number of secure kiosks into an environment where they may be prone to lightning strikes and power surges on a somewhat regular basis (southern Florida in a place where the existing electrical infrastructure is, shall we say, a bit out of date). Ideally we would use battery backups on each system, but it's not in…
I'm looking to play my .mkv files via Windows Media Center - I've got it almost working. They show up on the menu, they play video fine, but the audio is mute.
Strangely, if I play the .mkv file via Media Player - the video & audio are fine.
Any ideas?
I have an iMail 2006 server installation in which I have a particular user that has several aliases that all point to a single user (me, for the record). I've been copying all of my mail to GMail and reading it there, but it annoys me that I have to go back weekly and log into my mail account on iMail and delete between 6 and 10 thousand…
Running PostgreSQL 9.0.1, with streaming replication keeping one read-only mirror instance up to date. Auto-vaccuum is on on the primary, except for a few tables which are not vacuumed by the auto-vacuum daemon, in an effort to reduce business-hour IO. These tables are "materialised views".
Each night at midnight, we run a vacuum across…
Vista Home Premium locked up on 5/12/10 while on a website and could not get to 'control-alt-delete.' Mouse locked, too. On/off switch would not work (stayed lit) so I unplugged the power cord. When I tried to re-start the computer I could hear a fan running but it would not boot up, nothing on the monitor and no lights on the keyboard.…
What is the difference between using mod_proxy and mod_rewrite?
I have a requirement to send certain url patterns through the tomcat, which runs on the same host but under port 8080. I know this is something for mod_proxy, but I"m wondering why I can't just use mod_rewrite, or what the difference is?
Probably has to do w/ reverse…
I built a test lab using the Windows Server 2012 R2 Preview. The initial test lab has the following configuration (I have replaced our name with "OurCompanyName" because I would like it if Google searches for our name did not cause people to come to this site, please do the same in any responses)

Over the weekend a website I run stopped functioning, recording the following error in the Event Viewer each time a request is made to the website:
Event ID: 9001
The log for database 'database name' is not available. Check the event log for related error messages. Resolve any errors and restart the database.

Recently the script was working fine, but from some days I'm receiving such message, while running the readlink -f "$0" command:
readlink: illegal option -- f
usage: readlink [-n] [file ...]
I was running the following code to debug:
#!/bin/sh
DIR=`pwd`
RLPATH=`which readlink`
RLOUT=`readlink -f -- "${0}"`…
I have a pix 501 with 5 static ip addresses. My isp just gave me 5 more. I am trying to figure out how to add the new block and then how to nat/open at least one of them to an inside machine.
So far, I named a new interface "intf2", ip range is 71.11.11.58 - 62 (gateway should 71.11.11.57)

I'm running into a perplexing issue with Windows 8 Pro x64, where randomly I'm unable to drag to select multiple files (i.e. in Explorer or Directory Opus). I've also noticed that a similar issue happens when I'm running for example Photoshop or Illustrator and can't drag to select multiple layers, or drag to…
I have a that PC (Windows XP SP3) keeps losing time whereby it ends up being about 5 mins slow per day from all the other PCs and clocks about the place.
Is there a way to increase frequency of time server synchronisations to keep this in check? Or better yet, a reason for this issue, perhaps some recent…
I'm having issues getting SMB file shares working over a PPTP VPN.
The server setup consists of a security device (DrayTek V3300) which passes the PPTP authentication to a SBS2003 server running RRAS. The server is the DC and provides DNS and WINS, the single NIC's name server is set to 127.0.0.1, and DHCP…
Here's my situation, I've got a client hosting two servers (one VM), with the host providing VMware Zimbra, the other Windows Small Business Server 2011. Unfortunately, the person before me had configured this setup as follows.
Host:
Ubuntu Desktop Edition 10.04 (I know, again, not my choice) running…
My goal: given a list of files on local server, show any differences to the files with the same absolute path on remote server; e.g. compare local /etc/init.d/apache to same file on remote server.
"Difference" for me means different checksum. I don't care about file modification times. I also do not…
