Installation :: Running SLAX From RAM (Fast Access To Data)
May 14, 2009
Before the other day, I'd copied a live CD to ramdisk and run it from there before, but the disk was INX (INX is not X), a live CD based on Ubuntu that runs entirely in the text mode, no GUI. INX is a terrific product: colorful, educational, light, agile, fun to use, and and often damned useful, but when an OS only uses text, you may not notice how much running from the RAM speeds up an OS. Previously, I'd assumed that the best reason to run a Live CD from the RAM was to free up the CD ROM drive. When I started running a full KDE 3.5.10 Desktop from the RAM, it didn't take me long to notice the awesome boost in speed and performance.
The computer has the fastest access to the data that's in the RAM. (The "A" in "RAM" stands for "access", right?) So the machine is faster. As the RAM gets larger, I'm sure more and more live CDs are going to offer the RAMdisk option. Right now both INX and SLAX share the characteristic of being exceptionally small CDs, and that makes them well suited for this kind of application. The "minimal" version of Slax, the basic CD without any modules added, is less than 200 mbs, which fits very nicely on my 1024MB RAM. I now use the minimal SLAX cd to initiate the system, and I keep a collection of the modules on my hard drive to copy to the RAM and activate at will.
Here's a couple of screenshots: [URL] I'm using Wine here to run my one and only favorite Windows program, a text to speech program called READ PLEASE. Note that I am also running KTorrent, which is uploading from and downloading to my external MyBook hard drive. [URL]. Here's a shot of yakuake, which is sort of like Konsole with superpowers. I just upgraded my hard drive KDE system to 4.2.3, and they still haven't fixed Yakuake yet. I know it's been reported, so I'm sure it'll be taken care of.

I'm about to have a web server at home for the first time. I've always missed having full control and not having to contact my hosting company when I need to do some specific changes - and some changes they won't do for you at all.I've chosen the non-GUI Ubuntu Server with LAMP, and nothing more is installed really except for a couple of command line tools from the repository. The LAMP software has been locked down as good as I can by following some guides on the net and using common sense. Like Apache 2 don't have access to the file system except for the www folder, and setting the headers to Prod. MySQL has skip-networking and I've commented out the listen string to localhost. PHP has a truckload of functions that I've disabled in the php.ini, also by following some guides on the net, among some other security enhancing php.ini editing.
The only thing the server will serve is a well known PHP forum and some html docs, and that's all. Nothing advanced or complicated stuff, and I'm definitely not programming PHP myself or letting anyone do it for me.But I do want to sleep well at night knowing that my server is always on and sitting on the edge of my home network! And can I do that? I've heard that you don't need to be worried about getting your Linux server box hacked, but you should be worried about anyone getting root access to it. But is it really that simple? Ubuntu is shipped without root account and you must have the sudo password, right? What's the odds for anyone to get full access to my system?An issue: I've heard that Apache never must run as root. When I do a ps -ef, I see that there are several www-data processes running apache, but there's one root process running apache too. Is this normal and is it safe?An issue: I've heard that PHP can fail pretty easily. But isn't PHP running under apache 2 and limited by the www-data filesystem access?An issue: MySQL is running as a MySQL user, and I guess that's an unprivileged user right?

I have a Dell OptiPlex GX1 (CPU: Pentium II, 500Mhz). It's very old, and a while ago I installed an old version of Ubuntu on it. While it is switched on and booted up, everything is fine, however the trouble is when it is switched off, or just in BIOS.
The BIOS clock appears to be running at about 60x speed (eg minutes like seconds, hours like minutes). This happens both when switched off and when observing the clock from the BIOS menu. I really don't know what to do about this, and it's causing alot of problems, I've even had it get to the point where the system clock reset itself and would not recognise the OS as valid.

I am using AT91SAM9260 and running Linux 2.6.27 on it. Once i sync the Kernel clock and cmos clock with the reference clock and leave it for 1 day, i see a drift of nearly 8-10 sec. The kernel clock is running faster. How can i correct this?

I am developing a program in a system where the Linux does not take care of the sync command automatically. So I have to run it from my application always I save some data in the disk, which in my case is a 2GB sdcard. It is true that I can make the operation system takes care of the syncronization, using a proper mount option, but in this case the programm's performance drops drastically. In particular I use the shelve module from Python to save data that comes from a socket/TCP connection and I have to deal with the potencial risk of the system being turned off suddenly Initially I wrote something like that to save data using shelve:
Code:
def saveData(vo)
fd = shelve.open( 'fileName' , 'c')
fd[ key ] = vo
fd.close()
os.system("sync")
But that takes too much time to save the data. Note that I use the sync from the OS every time I close a file to prevent data corruption in the case of the "computer" being turned off with data even in the buffer. To improve the performance I made something like that:
Code:
def saveListData( list )
fd = shelve.open('file_name', 'c')
for itemVo in list:
fd[itemVo.key] = itemVo
fd.close()
os.system("sync")
Thus, first I saved an amount of objects in a list then I open the file and save the objects. In this way I have to open the file just one time to save a lot of objects.However I would like to know if adding a lot of objects before closing the file would increase the risk of data corruption.I known that turning off the system after fd.close() and before os.sync may cause problems. But what about turning off the system after
Code:
fd = shelve.open('file_name', 'c')
but before fd.close()?

I'm using using ubuntu 11.04, and im using Avidemux (GTK+) whatever date that is, got it a couple days ago from the software center.
I attached some .a/s/s subtitles to the video, and the preview looked great. Encoded the video, and the audio plays like two times faster than the actual video, so by about halfway through the video, the audio is done and im left in silence with the video still going.
I set the video to MPEG-4 AVC, attach .a/s/s subs, leave audio alone, and encode using default option (Single pass-quality quantisizer)

I am trying to use the Linux Ramdisk y machine and followed the instructions oninux/Ramdisk/ramdisk.html to create a 4GB ramdisk (total memory is 8GB, linux 2.6.9)The issue is that it is taking me almost exactly the same time to read a 1GB file from ramdisk as it is from disk. I was expecting it to be atleast twice as fast.Has anyone encountered this before?

Every developer in our organization has access to a single development server and all development ( other than basic experimentation ) is done on this server. This is primarily because there are several interdependent systems and having copies of these systems on each developers machine slows that machine down to the extent of making it completely unusable. All developers access this development server using ssh. Of course this implies that scp will also work as the sshd daemon is running making data vulnerable.
We are currently attempting to secure the code and data on this server from unauthorized copying and transfer.
Currently I am attempting to set up virtual machines on each developer machine that can then be used to connect to the development server. I have created a shell that does nothing but allow for the typing of one command that simply transfers ( ssh login ) the user onto the development server.
I am using virtualBox and ubuntu mini to achieve this.
Problems: The first question is if this is a reasonable way to achieve what I am attempting to. Is there a better way?
The others is more in terms of the set-up: I am attempting to resize the virtualBox console. I tried this by editing grub. Although I am able to resize the screen at start-up the entire screen goes back to ( what I believe is 800x600 ) after the Ubuntu splash screen.
The virualBox seems to have completely messed up the keyboard detection how can I rectify this?
The other is regarding the restricting of shell access I have currently done this by removing access to /bin/ for normal users. Is this secure enough or is there a better way?

We purchased a new database system at work last October, ditching the old system because of a lack of support from the vendor. This is a retail Point of Sale and Backoffice database system. I am not sure what system the new one runs on, but the system we replaced was a Firebird data base. The reason I am posting is because we are now in need of the information contained in the old database which was not completely imported into the new system.
Basically the problem is this: The database in on a Windows XP system and I found a copy of SQL Manager Lite 2008 on the system, which after quite a bit of studying, I figured out how to extract the database into a removable file. I have this file (178MB) on a USB stick in a file called Backoffice.fbd.
My studying suggests to me that I can get into this database with MySQL. I have never used this and have no clue how to do this. All I want to be able to do get into the database and create tab deliminated spreadsheet files for each of the database sections (Customers, Repairs, Sales History, stock files, etc.) Is it possible to do this with Ubuntu and MySQL and if so, can expert suggest one or two things to get me started. While a guided tutorial would be nice because I am not an expert, I am willing to learn on my own if someone could point me in the right direction.

So, I was playing with Fathom's new Slax Remix with Zen kernel 2.6.33 and decided to try a manual install to hdd and see if it would boot. [URL]. New slax remix is here: [URL]I surprised when after doing the install I ended up with a beautiful and fully functional KDE desktop all in 860MB of space! Although many things will break if upgrading, etc. I was impressed that with KDE running it was only using about 140MB ram! incl cache, etc. And, fluxbox is included too as well as pkgtool, and xwmconfig. The complete How-To I did is in the slax remix thread at above link, and also here [URL].
Hints:
After installing to hdd, usb-hdd, etc.
Grab slackpkg and the gnupg stuff and install any other pkgs.
Be careful about upgrading...
I added kdeadmin pkg from slax module and some other stuff so my install is at 944MB now
and look at output of "free" in screenshot.

I decided to finally give it a try last night and made a Live USB for Slax. It booted up quickly, pretty much everything worked right away, and after getting the Wifi working I decided to call it a night.
My project for today was attempting to install Java, but I haven't had much success. There are modules on the Slax site for this, but a. they are unverified and b. I want to delve into linux further than just downloading everything off a website. I downloaded the latest Java package for linux, which was a self-extracting .bin. I followed steps 1 through 4 here, but step 5 didn't work. I got the error message

UnZipSFX 5.50 of 17 February 2002, by Info-ZIP (Zip-Bugs@lists.wku.edu).
inflating: jre-6u20-linux-i586.rpm
error: db4 error(2) from dbenv->open: No such file or directory
error: cannot open Packages index using db3 - No such file or directory (2)
error: cannot open Packages database in /var/lib/rpm
I then tried using the rpm -UvH command on the rpm file, but got the same error. Knowing that Slax modules are .lzm files, I used rpm2tgz and tgz2lzm to convert it to a module, but it still doesn't work. I'm hoping that someone can point me in the right direction, other than "Download this unverified module from the Slax site."
In addition, a problem I haven't encountered yet but is foreseeable: In those instructions that I linked above for downloading and installing Java, the "Enable and Configure" section requires altering parts of the Firefox install directory. However, since this is Slax, Firefox is in a module. To do that part, do I have to use lzm2dir in order to get into Firefox's innerworkings, or what?

I am trying to connect to the net wirelessly using Slax off my USB stick. I did the best I could using the wireless configure tool but Firefox will not surf - no connection. The configure tool shows that I am 'partly' connected in that it shows signal strength in green but I noticed that there is no entry for IP address. Am I suppose to know this and enter it? In LMDE, I see the IP as 192.168.2.10 and other addresses. Do I need to enter this stuff?

Installing 11.2 from KDE LiveCD on an IBM ThinkCenter with 3.2Gb CPU and 1Gb RAM. Ubuntu 9.04 on first two partitions. I go through the configuration, click to 'install': Install display bars remain blank. After 2-3 minutes, black screen with scroll of attempted installation pieces and the error message: "Respawning too fast. Disabled for 5 min." Freeze.
Other posts mention problem with init. But this is happening with the install so not able to address that. No apparent md5chksum for LiveCDs. No mention of this problem in installation help guide. Does anyone know how to deal with this? If you need more info, I will provide. Though it seems this is not an unusual problem when booting an installed system, there's no mention of it happening during installation.

Sometimes I connect to the internet via a "wired" connection (interface usb0), sometimes via a dial-up connection (ppp0).
Stupid annoying arbitrary data transfer limits imposed by ISP make me want to keep a running total of data uploaded and downloaded, so I can keep an eye on this and hopefully avoid using up my allowance. program that will keep this running total for me, across all interfaces? Or maybe someone has a script that can do this?

There is text based game in the Ubuntu repos called gomoku (just 5 in a row) it comes with the package bsdgames. The manual page [URL] lists an option (-b) to run it in the background. I want to try that and if I know how it works create a simple graphical front-end. When I start the program with:
Code:
gomoku -b
it starts and remains active, the terminal does not return to prompt which is OK as the command is not finished. The manual says the program reads from stdin, and this might sound stupid but how to get anything there?
I've tried to pipe an echo command to gomoku which works but ends the program after is receives input.
Code:
echo "black" | gomoku -b
just finishes. After that when you type another command like:
Code:
echo "justsometext" | gomoku -b
gomoku tells it expects either black or white as input. So it forgot the previous "black" because it is a new instance.
How do I pass text to an already running gomoku?
