Writing to NTFS

Filed under: Driver, Kernel, Linux, Technolgoy, Tutorials, Utilities — rakeshvk @ 5:49 pm

The Linux NTFS project has released a beta version of its fully open source userspace (using FUSE) 3G-Linux NTFS support driver. According to the developer, this driver beats hands down other NTFS support solutions performance-wise (including commercial Paragon NTFS driver and also Captive NTFS, which is using windows ntfs.sys driver under WINE).” That’s right, writing to NTFS even works. Soon it’ll mean one less recovery disk to keep around, I hope.

How to access NTFS from Linux

Choose one of the following three options:
1) Linux has an integrated kernel driver. It allows reading of files, and rewriting existing files. It does not support creation of new files or deletion of existing files. It works out of the box in most modern Linux distributions except Redhat/Fedora. For details on how to use it, see the “How to mount NTFS” wiki page. Click here if you are a Redhat/Fedora user.

2) ntfsprogs includes an improved driver, ntfsmount, which provides the same functionality as the kernel driver. Additionally it also supports basic cases of directory, symlink, device and FIFO file creation, deletion and renaming. Note: That doesn’t mean it always succeeds, it is still experimental and might just as well refuse to complete an operation in order to prevent corruption. See the ntfsmount page for more details.

3) On 07/14/2006, project member Szabolcs Szakacsits presented a new version of ntfsmount and libntfs, currently given the project title ntfs-3g. This version has full read/write capabilities, many bug fixes and improved performance. It has already been downloaded over 45,000 times, tested and regularly used by users with satisfaction over the last two months. Despite of that it is still a strong beta, and will upon (in some way or the other) merge also into the linux-ntfs ntfsprogs package.

The beta version of the ntfs-3g driver can be downloaded from http://mlf.linux.rulez.org/mlf/ezaz/ntfs-3g-20070920-BETA.tgz

Automate interactive transactions with Expect

Filed under: Technolgoy, Utilities — rakeshvk @ 6:06 pm

Did you ever wish you could automate your interaction with a program, making a script that can smartly handle an interactive session? You can — with Expect, an extension to the Tcl programming language whose purpose is to communicate with interactive applications.

You can write Expect programs that automate live sessions, handling any tasks where a user interacts with the system. This suggests a multitude of uses, but where it has been most popularly applied is in software testing and in automating network transfers, such as site updates or downloads.

Expect is a product of the US government, having been created by Don Libes, a computer scientist at the National Institute of Standards and Technology (NIST). It has been around for years, and while its functionality has stayed the same, the reason for using it keeps changing.  >>>>

Ghost for Linux – A hard disk and partition imaging/cloning tool using compression and FTP.

Filed under: Linux, Utilities — rakeshvk @ 9:23 am

Ghost for Linux is a hard disk and partition imaging and cloning tool similar to “Norton Ghost”(c) and ™ by Symantec. The created images are optionally compressed, and they can be stored on a local hard drive or transferred to an anonymous FTP server. A drive can be cloned using the “Click’n’Clone” function. g4l supports file splitting if the local filesystem does not support writing files >2GB. The included kernel supports ATA, serial-ATA, and SCSI drives. Common network cards are supported. It is packaged as a bootable CD image with an ncurses GUI for easy use.
