Ello everybody,

I'm looking for an answer to why, if linux has a built in function that cache disk writes, would I need a cache on my RAID card?

Is it a "bad" caching feature in some way?

I have alot of servers, now I'm working on a laboration server to have at home, nothing important on it so I don't need a RAID-card with a bbu for write security or anything like that.

What I do need is some speed...

The RAID card that I have left over have no cache at all. The card works perfectly except the performance is really bad. It has to confirm all writes to disk and that takes an awful amount of time.

I used a SSD-drive for handing the cache and that works alot faster, problem with SSDs is that they can only handle so many R/W before they die.
I can use a RAM-drive also.
I can buy a RAID-card with cache.

But why don't the built in function handle it for me?

Best regards

Johan

I issue the following command:

root(at)bt:~# cut -d "\" -f1 filename.txt

and then get put into the following prompt:

>

I then have to hit cntrl C to get out. Does anyone know why this is happening?

I should add, that the text inside the file reads something like below:

word\randomstuff
word2\morerandomstuff
word3\random

Hi everyone,
My son has access to my laptop and ended up changing my logon password on my Vista and now he has forgotten it. I have latest Knoppix 7.0 Live CD and googled instructions on how to fix this. Most instructions I've found are using earlier versions and am getting little confused. Can anyone help point me to more current instructions or should I download an earlier version of Knoppix. I am using Knoppix 7.0 Live CD.
Many thanks for any help.

I deleted a few old partitons but the partitions still appear in /dev after rebooting. partprobe see's the changes and works but they still show up after rebooting. is the partition map being cached or something?

I have two computers, one with an i815 onboard video chip and the other with an i915. A console font that is perfectly readable on the former appears only half-size on the latter, requiring me to use a larger font size. Can anyone explain to me why that happens?

I have limited Linux knowledge, and only on a single computer. I was wondering: In a business setting, people log onto their machine from any location within the building (as an example) which is verified through the windows server. Is it basically the same for a Linux environment? If I was to set up a classroom with a dedicated Linux server, could students log onto their local machine anywhere in the room and still be able to get on?? If so is there a free Linux Server distribution that I can download?? Hope this makes sense and thanks in advance!

Hi guys

I'm struggling to recover some files off of a slightly damaged NTFS partition. Tried searching but can't find anything relating to this specific issue.

Basically the MFT seems to be corrupt. Ive tried CGSecurity TestDisk, which recovers deleted files perfectly, but won't recover files that are actually stored in the partition. It has a "List Files" option which fails with a corrupt partition message (I guess it's trying to read the partition as if it were healthy).

I would try PhotoRec but it doesn't recover file names or paths.

Surely there is a way to low-level read the healthy parts of the corrupt partition in a few minutes considering it only has minimal damage?

I know. It sounds like I'm making this up, or my keyboard is hooped. But just this morning I logged in as root to restart nfsd. I typed

service nfs restart

but what came up was

srvic nfs rstart

I know that everything was good a couple days ago. I don't log in as root much these days. First I thought it was my usb keyboard that I got about a week ago, but, no, on another terminal logged in as user lowercase 'e' works fine.

So I did a bit of diagnostics. Shift-e 'E' works normal. Control-e works normal. showkey (-m/-k/-s) works fine. xev shows it like normal. The only way I can get lowercase 'e' to show at command line, or anywhere for that matter (as root), is to go Control-V e, like I'm trying to get a literal control character in the line. Kind of a pain. I tried xterm, rxvt, gnome-terminal, same thing.

Anyway, I bash at programming pretty hard sometimes, my uptime was about 2 weeks, so I shrug, figure it's time to reboot. That'll cure it for sure. Well, after reboot, and before XSession, virgin system, I first login on tty1 as root. Dagnabbit! The problem is still there! I login tty2 as normal user, lowercase 'e' is fine. So I checked the rest of the keyboard. Every other key works fine. Shift/Control combos, you name it, all good. My poor little lowercase 'e' has got lost!

I suppose what is most funny, is that this could be a cute trick to pull on someone, if I could figure out what the heck is causing it. My root login is plain jane. I have a couple aliases set up and a few convenience scripts, but otherwise I never get fancy with root. My normal user I get as fancy as I like, but never with root.

Can anyone think of anything that would trap lowercase 'e' from being entered? And why only with root?

Hello Everyone,

I am new to both the Linux OS and this Linux forum as well, so I hope that everyone can just bare with me a little bit.

I am excited to have made the choice to enter the world of Linux. In making this transition I am coming from using Windows XP, and with that being said I have quite a bit of software that I would like to be able to use under Linux.

I am aware that Linux has a great deal of software created to replace popular titles used on Windows and Apple based operating systems, but there are many programs that I don't want to let go.

In doing research in the past I have seen a couple of different options of how to handle this such as...
1.) Running Windows XP in a Virtual environment
2.) Using a program such as Wine HQ

However, I have not yet tried these above methods out. I don't really want to run Windows in the way that most virtual environment programs work in and Wine HQ doesn't support all programs and or newest versions of them (although this is a pretty amazing program when you think of what it is capable of).

Also just to give more information, I am currently using LinuxMint.

Now to my question, and I know there is a little bit of a line to be crossed here.

Not sure if it makes sense to anyone, but I am looking for a method of incorporating my Windows XP into Linux seemlessly to the point where you don't even know that Windows XP is running the Windows based programs.

The two general ideas I have for accomplishing this are (I know both of the ideas kind of overlap each other)...

1.) Some kind of coding that allows you to install Windows XP onto your system as well and be able to run Windows based programs under Linux but through Windows XP itself.

2.) Some kind of virtual environment where it just opens the Windows based program immediately without having to open up the virtualization of Window XP and then have to use Windows XP in a window and open the program through that.

Now I am sure that hardcore Linux users would not want Linux and Windows to touch in anyway, but I am just trying to make my transition as smooth as I can.
I also know that my above ideas may be far fetched, but I have seen some and heard of amazing things that Linux coders can do, so I figured I would see if anyone has any ideas.

I thank you all in advance for reading this and for any help that anyone can share.

anyone know how to integrate/configure likewise to quit asking for the domain passwd upon successful two-factor authentication via RSA pam agent on a RHEL 6.x machine?
