This is your host, Mark Walker—now let’s get to the content.
This episode, number 34, was produced on December 30th, 2012—and today’s topics will include:
Selections from “yum info recent” from several yum repositories … and the Latest from FredLUG, the Fredericksburg Linux Users Group.
Today’s feature is “Basics of File Permissions,” from the The ABCs of Linux series of FredLUG presentations.
And we’ll close with a Creative Commons licensed work by
JT Bruce, entitled Temporal Distortion.
Here are some recently updated items in the yum repositories:
1→Name: Zim
Summary: Desktop wiki & notekeeper
Description: Zim is a WYSIWYG text editor written in PyGTK which aims to bring the concept of a wiki to your desktop. Every page is saved as atext file with wiki markup. Pages can contain links to other pages, and are saved automatically. Creating a new page is as easy as linking to a non-existing page. Pages are ordered in a hierarchical structure that gives it the look and feel of anoutliner. This tool is intended to keep track of TODO lists or to serve as a personal scratch book.
2→Name: fail2ban
Summary: Ban IPs that make too many password failures
Description: Fail2ban scans log files like /var/log/pwdfail or
/var/log/apache/error_log and bans IP that makes too many passwordfailures. It updates firewall rules to reject the IP address.
3→Name: opendyslexic-fonts

The typefaces includes regular, bold, italic and bold-italic styles. It is being updated continually and improved based on input from dyslexic users.
4→Name: rssh
Summary: Restricted shell for use with OpenSSH, allowing only scp and/or sftp
Description: rssh is a restricted shell for use with OpenSSH, allowing only scp and/or sftp. For example, if you have a server which you only want to allow users to copy files off of via scp, without providing shell access, you can use rssh to do that. It is a alternative to scponly.
5→Name: tw

Ted Brunell is the presenter—I like to call it our own personal “Ted talk.” (Sorry, couldn’t resist the pun.) In this talk, Ted covers Linux file system settings and SE Linux tweaks, to ensure users get to their content, and only the content they’re supposed to view and change.
Today’s podcast will close with a Creative Commons licensed work by JT Bruce, entitled Temporal Distortion. Enjoy.
