Configure KeepNote Helper Applications In Backtrack Linux

Insights3 Comments

I use KeepNote for taking notes in Backtrack. It is important to document progress on projects or simple notes about file locations, specific command switches, or other information that could get lost in the shuffle during a work session. KeepNote provides the functionality necessary to organize notes and search note content as necessary. On Backtrack it is beneficial to configure KeepNote’s Spell Check as well as KeepNote Helper Applications so you can benefit from the full potential of KeepNote. Below we describe some errors you may see when attempting to use certain KeepNote functionality and how to resolve them.

I was going through and cleaning up some plugin settings recently on a WordPress site and received an error when attempting to access Feed Comments Number admin settings page. The error states that you do not have sufficient permissions to access the page though that was not the case because I was logged in as an administrator. Luckily I had run into this exact error awhile back and knew exactly where the problem was. Below I describe the error in more detail and provide resolution to the issue.

Changing the default text editor to vi on Ubuntu is fairly easy however it may be tricky depending on how it has been set since there are numerous ways. In BackTrack Linux for instance the default editor is set using select-editor so if you follow another Ubuntu Linux howto it may tell you to modify the default editor using update-alternatives. Below I describe setting the default text editor using both of the mentioned methods and note a couple other locations where it can be set.

Change vi Defaults To Not Display Line Numbers When Editing Files On Linux

InsightsLeave a comment

Recently I was contracted to do some work for a new client that had around 25 CentOS Linux and Ubuntu Linux servers. The client needed various system administration tasks completed such as updating the servers, modifying a couple scripts that performed automated tasks, and a couple other basic tasks. I typically use vi to modify scripts or text files on Linux servers so when I started to perform my tasks I started getting annoyed as the vi default configuration included the line numbers which makes it a pain to copy/paste from the files you are editing. You can obviously turn off the line number display by typing “:” followed by “set nonu” (both without the quotes) however that does get old. Use the information below to change the default vi configuration so line numbers no longer display by default.
