Fix ' VMware not connecting to internet' issue.

By
VMware may stop connecting to the internet due to various reasons. One most common issue is that the NAT service  stopped working. Windows might automatically stop this service due to various reasons.(Usually during Windows update). The easiest way to fix this is start the service manully in task manager. Steps: 1. Open task manager. 2. Open Services tab. 3. Locate VMware services. Right click and start if not running. Well, I hope in the later versions, VMware checks if the service is running or not automatically and solves the issue :)

Fix for eclipse oxygen icon not displaying in ubuntu.

By
There is a bug in the latest version of eclipse IDE. The icon is not displayed. If you are facing the same problem then I might have a fix for you. There are various reasons why this may occur. One of the problems is caused because icon of eclipse is not present in pixmaps folder. To add it simply copy the icon of eclipse into /use/share/pixmaps folder. Note: You need to have root access to do that.  Also, make sure the name of the icon is eclipse.xpm  For this, use the terminal to fire the command: sudo cp /eclipse_path/icon.xpm /usr/share/pixmaps/eclipse.xpm Here replace the eclipse_path with your eclipse folder path. E.g. /home/leena/eclipse/java-oxygen/eclipse/icon.xpm

If you have the following Ubuntu error, I might have a fix for it. fsck from util-linux 2.26.2 /dev/sda1 contains a file system with errors, check forced. /dev/sda1: Inodes that were part of a corrupted orphan linked list found. /dev/sda1: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.         (i.e., without -a or -p options) fsck exited with status code 4 The root filesystem on /dev/sda1 requires a manual fsck Busybox v1.22.1 (Ubuntu 1:1.22.0-15ubuntu1) built in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) _ And believe me help command does nothing. Solution: Just fire a simple command to execute  fsck manually. fsck /dev/sda1 If some other filesystem is causing the error then mention that name after fsck. It will show some processing. If it asks any questions like Fix(y/n)? always enter y . In the end when (initramfs) reappears enter: reboot Well, that's all! It worked for me. Hope it works for ...
