‘attempt to access beyond end of device’ Linux Error

Filed under
Linux

Alike other operating systems’ kernel, Linux Kernel is the resource of various services to the system. While the Linux Kernel errors occur, it generally indicates problems with file system or some memory that it can’t get access to. In some cases, the solution may require Linux Data Recovery for the cause- data loss. Users may get an error in sys log, similar to:“attempt to access beyond end of device”The error is generally encountered while attempting to access a Linux partition, trying to mount it or while starting the system. The error specifications also include rw, limit and want parameters that define some sector numbers. BackgroundThe reason why the error message occurs is that system tries to access such sectors that are not there on disk. If Linux file system is corrupt then the including metadata information like control block or directory communicates incorrect location of inode, which actually doesn’t exist. But when the device driver looks for it on disk, it fais and an error, like above, is encountered.SolutionDamaged file system needs repair. So fsck can be used to correct this corruption. But if the extent of damage is high enough then fsck may not help. In this case, it is required to recreate the file system by disk formatting and recover the data from backup. If data backup exists in required state i.e. complete and intact, it will provide data restoration. However if it fails or doesn’t exist, Linux Recovery applications can be used to extract lost information from affected drive. Linux Data Recovery software are graphically rich tools that use scanning procedures to analyze and recover data from failed hard drives. These recovery solutions are valid to be used in each logical data loss case, except from data overwriting. The applications are safe as of read-only design. Also, they offer suitable options that permit recovering and restoring recovered information to the desired location. The applications are installed on other than affected drive in order to prevent overwriting. Stellar Phoenix Data Recovery Linux is the best and safest Linux Recovery application to be used with ext2, ext3 and reiserFS file systems. The software is known for using the most potent scanning algorithms and for offering interactive interface. We can use this application with most of Linux distributions including Suse, RedHat, TurboLinux, SlackWare, Gentoo, Fedora Core, Debian, Ubuntu and others.

  • Rugged Kaby Lake vehicle PC does it all on the road or rail

    Vecow’s Linux-friendly “IVH-9024MX ICY” in-vehicle PC runs on a 7th or 6th Gen Core or Xeon CPUs and offers triple displays, 6x SATA bays, 4x PoE+ ports, 2x mini-PCIe, and EN50155: 2017 and EN45545-2 railway compliance. Vecow unveiled the rugged IVH-9024MX ICY back in June as an all-purpose in-vehicle and rolling-stock computer and this week announced certifications for EN50155 and EN45545-2 (fire protection) railway safety standards. This is the first 7th Gen Kaby Lake based fanless embedded system to receive these certifications, claims Vecow.

  • Exploring Zyxel GS1900 firmware with Ghidra

    Earlier this year the NSA released Ghidra, a reverse engineering suite with support for a large number of CPU/MCU instruction sets. While I have some experience with Hopper and radare2 I wanted to play with Ghidra to poke around the firmware for my Zyxel GS1900-8 switch which runs on a 32-bit MIPS CPU. All in all this has turned out to be an interesting exploration of both Ghidra and the GS1900-8-2.40(AAHH.2)C0.bix firmware image.

    Initially I wanted to write about poking around the firmware image and showing how one can use Ghidra to explore unknown binaries, but whilst looking around some libraries that are used by this switch I realised there is actually an interesting vulnerability to write about.

  • Linux Foundation Training Announces a Free Online Course-Introduction to Hyperledger Sovereign Identity Blockchain Solutions: Indy, Aries & Ursa

    The Linux Foundation, the nonprofit organization enabling mass innovation through open source, today announced enrollment is now open for a new, free, course – Introduction to Hyperledger Sovereign Identity Blockchain Solutions: Indy, Aries & Ursa. This course is offered through edX, the trusted platform for learning. To the surprise of absolutely no one, trust is broken on the Internet. Any identity-related data available online can be subject to theft. Breach Level Index says that over 5,880,000 records are stolen every day. The 2019 MidYear QuickView Data Breach Report shows that reported breaches in the first half of 2019 were up 54% compared to midyear 2018 (over 4.1 billion records exposed), with web being the number one breach type for records exposed, and hacking being the number one breach type for incidents. Wherever you go online, the advice is the same–make sure you understand what is behind each button before you click it.

  • Is the future of farming under water?

    "[The] first thing we did was open source our model. In the new economy, we make things accessible to everybody. Anybody with 20 acres and a boat and $30,000 can start their farm and be up and growing the first year. Our farms require minimal capital costs and minimal skill. The potential of replication is tremendous: A network of small ocean farms about the size of Washington State could feed the world and, as bio-fuel, replace all the oil in the United States, while simultaneously capturing five times the amount of carbon as land-based plants," Smith predicts. The 3D ocean farming model consists of an underwater rope scaffolding system, anchors on the floor, and ropes up to the surface as well as horizontal ropes. Farmers grow their crops within this system, such as kelp ("the soy of the sea"). Mussels, scallops, and oysters are grown on the floor, and plants are grown in the mud. GreenWave is disseminating its model for restorative 3D ocean farms through open source manuals, farmer training programs, and an online collaboration platform to create a network of restorative ocean farming communities. Outside of ongoing replication along the waters of Long Island Sound, 3D ocean farmers anywhere in the world will be able to select appropriate native species to restore productive ecosystems along the coast, as reported by the Buckminster Fuller Insititute.

    Deep learning refers to an emerging area of machine learning that uses artificial neural networks to make decisions on our behalf as they are more reliable than human decisions. It consists of many interrelated fields including natural language processing (NLP), cognitive computing, recommender systems, board game programs, and image recognition. Ever since its takeover by Google, DeepMind has become the world’s foremost deep learning neural network. Let’s look at the story behind the AI engine, its ongoing applications and whether you should have concerns about privacy in the smart devices where it’s used.

  • What's EPEL, and how do I use it?

    RHEL ships with only a subset of packages that you'll find in Fedora Linux. This makes sense, because there's a lot of software in Fedora that isn't needed in an enterprise environment or falls outside the scope of RHEL. Red Hat maintains and supports the packages in RHEL far longer than the lifespan of a Fedora release, and we select the software we feel is necessary for our customers to be successful in deploying and using RHEL to run their workloads. But Fedora users sometimes find that they miss this or that application that's available in Fedora but not through RHEL. So, EPEL was formed. Extra Packages for Enterprise Linux (EPEL) is a special interest group (SIG) from the Fedora Project that provides a set of additional packages for RHEL (and CentOS, and others) from the Fedora sources. To get a package into EPEL, it has to be in Fedora first. EPEL follows the Fedora Packaging Guidelines to ensure successful integration, and only includes free and open source software that isn't patent encumbered. So you won't find any proprietary software in EPEL or things like multimedia codecs that are restricted by patents, even if software enabling them is under an open source license.
