Ubuntu :: Portable Air Conditioner For Equipment Closet
Jul 7, 2011
I haven't heard of anyone doing this and I am wondering why not. I have an equipment closet. Where I have a home server, network gear, directv box, dvd player, stereo system(yet to come). I have only heard of people putting fans in such closets and wondering why not a portable air conditioner? I am thinking I want a
SOLEUS AIR PE6-10R-03 Portable Air Conditioner from new egg for about $315
It claims 45db 256 CFM and 2 pints/hour dehumidifer. That sounds perfect to me for a media closet but am wondering why I don't see others using a portable air conditioner for a media closet? They had a cheaper unit but it doesn't claim to have a fan which I think circulation is a must for a media closet. There is even a drain that is on the other side of the wall that I can run the drain pipe to. All I need to do is run a exhaust duct through the attic and to an exhaust that I can put in my roof overhang.

I apologize because I know this is really a worn out question, but I have a reason for asking. My wife gave me this laptop in December 2003 as a Christmas gift. At the time it was state of the art and she spent over ?1100 on it. It is a Samsung V25, P4 2.8Ghz 1GB memory 40GB HD. It still has the original XP home OS on it, and when I got a new laptop a couple of years ago, I let her have it to use because she refuses to use Linux and she did not have a laptop. Well, she stopped using it when she got netbook and it has been jut lying around. After so many years of use, as you might expect Windows now just crawls with so much crap on it and is very unpredictable (might work might not.)
My thought is that she might start using it again (and I certainly would), if I could show her that there is still plenty of life left in it. I KNOW that Slack will be faster, but before I wipe the drive (she is still kind of sentimental about me doing that), and I want to see if I can get a couple of comments about the hardware and what trouble I might expect. I ask because I have tried dozens of live CDS, and some work and some don't. For example, the newest Knoppix would not run (freezes when it tries to start X.) Anyway, the specs are
Display: Intel 82845G/GL/GE/PL
Sound: Crystal WDM AC'97 ICH4
This thing has most of the goodies that loaded laptops offered in those days (i.e. 1394 port). I am most concerned about the display because I have read about others who have had difficulty with Intel graphics. It is my intention to -Current on it, since it runs great on my main laptop. So if someone could just offer a little bit of their experience with similar old equipment

I'm planning to centralize users and passwords and also create controls for user access to some equipment, for example, Linux Servers, Switches, routers and firewalls. In case of failure of the link between the ACS and AD or equipment to the ACS, this device would use local username and password.
At the moment, my AD structure is a Microsoft, Cisco ACS servers and Linux Standalone. I wish that both linuxs servers and network equipment were authorized by Cisco ACS on the accounts that are in Microsoft AD.
The configuration of the Cisco ACS to use the AD is done and no problems, the network equipment is OK too, but am having difficulties configuring the server for this solution.

Due to hardware failure I have had to set up a server several times. Each time it takes more than a day to set it up from scratch and import the databases etc. I would like a solution that separates all the data, including the configuration files, from the binaries and stores the data on a portable medium that can be quickly used to setup a new server.
Here are the details. I don't use Apache Friends' xampp, instead I set up apache2, php, mysql according to the instructions in [URL].. So the php, css, html etc files are in /var/www, the apache config files are in /etc/apache2 and the mysql data is in /var/lib/mysql. What is the simplest way of making the data and configuration files portable so that I can quickly set up the same server on a new machine that I have first installed Ubuntu on?
Can I put the above mentioned partitions and directories on a usb drive? Should I always make regular dumps of the mysql data and use the dump files instead? Should I keep the whole lot on the local hard drive and find a way using rsync, unison etc to mirror the files onto another potential backup machine on a regular basis - this is not a trivial operation if all the file permissions and ownerships are to be preserved.

I'm looking to setup X11 forwarding on my machine and secure it either with a vpn or ssh. A portable x11 client is need for access on the go. I am not sure if I am over complicating the issue but security is a must and some app I can run in windows on a thumb drive is a must.

I removed my old 160Gb laptop drive to install a new 320Gb drive. The 160Gb drive is partitioned as follows: 20Gb unallocated partition, 115Gb ext3 partition (running ubuntu 10.04), and 5Gb swap.
I placed this drive in a portable enclosure so that I could retrieve data from it. The Disk Utility in Ubuntu recognizes the drive but the partitions are not recognized, shows unknown and the only option available is to format the volume. If I place the drive back into my laptop, the drive boots normally and data is accessible.
I have connected other portable USB drives and they work (NTFS formatted), so USB ports are not the problem.

My portable HDD is suddenly saying that I don't have write permission anymore.
properties>permissions says that I have full read/write permission over the top folder of the drive. After looking in the permissions I'm out of ideas.
I checked the properties of the drive itself and it said "Permissions could not be determined"
I haven't changed the permissions deliberately - I use this hard drive every other day to move movies across to my TV.

An application has made an attempt to load the C runtime library incorrectly. contact the application's support team for more info" I have tried re-installing several times now. Even downloading a different version. I am also running it through wine through the following command.. "wine "C:Program FilesPhotoshopPortablePhotoshopCS5Portable.exe"

I have spent the summer and just got my few must-have Windows programs over to Ubuntu 11.04 (64-bit), got it customized with Docky (under Ubuntu Classic) and everything is SWEET. (But don't get me going on Unity dock). One problem: if I boot with my 1TB portable hard drive plugged in Ubuntu will recognize it. If I plug a portable drive in after the boot, I get this error below. I tried Mounting manually and with Archive Mount

I got a CentOS 5.3 fileserver machine (no monitor/kb/mouse). I'd like to "pair" it with a specific USB drive, so that when this USB drive is connected and mounted it would start a backup - just a simple cp /source /target will do for now - it's the "autorun on mounted a specific USB drive" part I can't really solve. Is there an elegant way to do this some sort of autorun? My only really rough idea to do it is to check if the USB drive is available with a script run in crontab every minute :-

Well, I want to be able to run some Linux in a VM at my school (on WinXP systems), via a USB stick.Two problems:
- Computers are mediocre
- Will be on many of them
I tried portable virtualbox but it starts very slow and runs slow without the guest additions. It just doesn't work right.What I need is a quick, portable VM that starts up quick and runs decently; I'm not expecting all that much from a USB stick but at least smooth cursor movement.I would like one that allows me to save changes on the virtual HDD, as opposed to a LiveCD style VM.

I'm using Zabbix on which I can use give bash command to the agent.This 1-liner will give me all the interfaces with their IPv4 addresses.I have a 2nd expression which returns a checksum so I can detect a difference whenever someone deletes/adds/changes an ipv4 interface.This is the output on my Ubuntu-server:
Code:
~# ifconfig | grep -B1 ' inet ' | grep -oE '(^[a-z0-9:]*|addr:[0-9]+.[0-9]+.[0-9]+.[0-9]+)'
eth0

I have a 60 GB Hitachi hard drive and a Rosewill drive enclosure. The drive originally ran Ubuntu on my laptop. I reformated a couple of times with a different formats and it works in Ubuntu. However, Win XP and Windows 7 reads and loads the enclosure but the drive never mounts nor is it visible in explorer.

I had PS CS5 portable running with Wine and everything was fine. However, from a couple of days ago I click on the icon to open the application and it keep loading. I had attached a screen-shoot with more details. I am running Ubuntu 10.10 and Wine (wine-1.3.7).

I have OpenVPN setup and running on my home server (Lucid Lynx). I move around alot and use Portable OpenVPN to connect to my home server. The problem is a lot of the computers I use I do not have admin rights to install the necessary routes to connect. So my question is this. Can OpenVPN be configured to use PPTP protocol? Because I have PortableVPN on my U3 flash drive and that VPN client does not need admin rights to run. If OpenVPN cannot do this, and from my understanding of its archetecture it cannot, but I must admit i am no authority on the matter. Can you suggest a workable solution, ie. install and setup this server software and use this portable client software.

If I have Ubuntu installed on a USB drive and run it on a PC (not installing to the PC...just running the Live version), is anything at all written to the host PC's hard drive? I don't want the host PC's hard drive to be written to at all for security purposes. I'd be using Firefox, LibreOffice, and other apps that come with the Live USB version.

How can I get around this? Is it enough if I remove cryptsetup? AFAIK, my devices are not encrypted (at least /etc/crypttab) is empty).

After plugging in my mp3 player to usb it isn't detected, even though it powers up and charges. I do an fdisk -l and nothing. My lspci shows the controller and my mouse is detected. lsusb shows the Phillips gogear as the device and it is device 2. I did dmesg and at the end it showed
scsi 6:0:0:0: Device offlined - not ready after error recovery
I don't know if this is the issue or not but it's the only error I get, so I assume it's the problem.

I have a 650Gb HDD usb drive that I wish to use with ubuntu 10.04LTS aswell as on a WINXP system. HDD is clean. My ubuntu system has a /home partition formatted to EXT3, but as I use IFDRIVE to read this partition from windows, it needs to be set to have inode of 128 eg (mkfs.ext3 /dev/sdb1 -i 128)
my way of thinking is I need to partition the drive, format the drive to EXT3 making sure that is set inode to 128 How do is the best way to do this?
Then I need to get ubuntu to talk to this drive when I plug it in How do I do this?

I need a portable emacs to use for troubleshooting GNU/linux machines. A USB stick is the preferred medium as some of the computers I will work with may not have an optical drive.
Will I need separate versions for 32- and 64-bit systems?

I've created a wonderful (until this issue) portable copy of Ubuntu linux that will boot on mostly anything by using a USB enclosure for my laptop's 80GB SATA drive. So far so good, it boots and runs on everything, and on non-nVidia card setups was even detecting the drivers, or letting me install the required drivers for hardware acceleration and compiz. Because you know, the wobble windows are the most awesome thing ever.
Anyway, my desktop machine had an nVidia card, so I'm thinking, sure, I'll just install the nVidia drivers like before and everything will work happily. Not so-- now the desktop and any other nVidia cards work great, but it seems to have completely disabled any other graphics cards. When the kernel module detects that an nVidia card isn't present, it shoots up this nasty little dialog box giving me the option to boot into "low graphics" mode, which doesn't even allow me to use the correct screen resolution, much less see the installed graphics card and try to configure a driver for it.
Is there any way to configure Ubuntu (with the dreaded nVidia kernel module) so that it can use nVidia's drivers when an nVidia card is present, and default to the normal (not low-graphics) setup in other cases, so that it has a fair chance of using what's actually present? I'm not afraid to much with config files, I just don't know the underlying system well enough to feel comfortable diving in without a push in the right direction.
