Ep-006Honkeymagoo talks about Shred, MakuluLinux & users and groups

Shred “when you absoluytely have to kill everything on your hard drive.” This program will overwrite a hdd or partition with all 1’s so that all data is unreadable
• as root shred -n 2 -z -v /dev/sda
• the -n defines how many times you want it to write to the hdd. The default is 25.
• -z is to do one last overwite with zeros.
• -v is for verbose and shows progress.

• MakuluLinux is a Debian-based distribution providing a sleek, smooth and stable user experience on any computer. It includes pre-installed multimedia codecs, device drivers and software for everyday use. (I figured this would save me the time of doing all the work myself)
• You can download it in Xfce, Kde, Mate, Enlightenment
• I downloaded the Enlightenment version. It came preloaded with many themes, wallpapers, start up graphics, etc.
• the best part is the Sources.list file. its pulling from:
• Debian Testing
• Debian multimedia
• Linux mint Debain main
• Solydxk main upstream (an unoffical LMDE variant)
• Then ones for Opera, Google Chrome, Google Earth, Google Talk, Google Music, and Skype

users and groups:
• Makulu is nice but it comes with a pre setup user “makulu” and password for both user and root “makulu”. This of course is no good so I had to create a new user, give it sudo permission. Change the root password. Then I when I logged into e17 I found out that the created user could not shut down the system in e17. I had to log out then shut the system down from the login screen. So I had to create a group called “power add”, give the group permission in the /etc/enlightenment/sysactions.conf to halt, reboot, hibernate, and suspend.
• to add a user, as root type: adduser username
• to give a user sudo access it is simplle just as root or with root permission type: adduser username sudo (of course this assumes that you already have sudo installed or setup on your system)
• now to change the root password is very easy just type in: su root to switch to the root user than type in passwd and then enter in your new root password
• now I can’t say for other DE but in e17 a default new user does not have permission to do things in elightenment like shutdown or reboot the system. So this is what I had to do
• first as root or with sudo create a new group called power by typing: groupadd power
• then just like when you added a user to the group sudo what you want to do is add your new user to the group power by typing (once again make sure you have root permission): adduser username power
• Then using your favorite text editor edit the /etc/enlightenment/sysactions.conf file like this:
sudo nano /etc/enlightenment/sysactions.conf
• then go down to the part of the file that says group: plugdev allow: * add to the next line group: power allow: halt reboot suspend hibernate
• then reset the machine and log in as username and you will now be able to shutdown reboot etc
• Finnaly now that you have your new user added with sudo and power permission and the default root password has been changed it is time to clean up and kill the old default user.
• with root permission type userdel -r username this will delete the user and the users home directory

FiftyOneFifty discusses the IRC bots Phenny & Madcow

• Phenny (by Sean B. Palmer, who has now moved on to saxo, ) is the template for most, if not all, Python based IRC bots
Download and extract, run downloaddir/phenny
• Edit ~/.phenny/
• edit nick =, You will need an unque nick, not registered to anyonre else
• host = ‘server’ ie
• channels = [‘#channelname’, ‘#otherchannelname’]
• owner = ‘yournick’
• password = ‘yourIRCpwd’
• admins = [‘yournick’,’friendsnick’]
• launch bot with ~/phenny/phenny
• set cronjob to reload phenny on reboot of local server
• We tried phenny on my server for a while, but it proved unreliable on rejoin after netsplits (we set up the IRC during a period of frequent DDoS against Freenode)
• We tried MadCow, but it was unreliable delivering messages — Botname tell user <message>

Kwisher talks about the IRC bot Jenni

Jenni IRC Bot – provided by Michael Yanovich
Jenni Wiki

• download & extract zip file from jenni Github – I chose to do this in my /home, not recommended to run as root
• cd to the jenni-master folder and view the file
• run the script file with ./jenni
• edit the main config file – ~/.jenni/
• to start jenni run ~/jenni-master/jenni
• LugB0t is running on a Raspberry Pi

• Tony Beemus provided a script that will start the bot at boot and check that it stays connected after a netsplit
• Delwin wrote us a python module to display the next show recording – type .ns in the irc chat input

HonkeyMagoo talks about his expeience at NELF 2014

•Held at the Residence Inn Marriot Hotel in Cambridge, MA
•Got there early and talked for a while with a guy who works in IT for a school system in VT. He converted all his middle school kids to Ubuntu.
•Got to meet Tracy Holtz, Russ Wenner, Martin Obando, Pokey, Flying Rich, Door, Jonathan, and Bruce. I also got to talk to a person by the name of Will Weaver. He gave a talk on docker that I am sorry that I missed. Docker seems very interstinig and hope to try it out soon. I missed his talk but all of the talks are posted on

The talks I saw were:

• Jon “Mad Dog” Hall: My twenty years in Linux
• Chad Wollenburg: Open Source in Education
• Paul Asadoorian: The 10 Commandments of Embedded Device Security
• Tracy Holtz: Open Source in Small Businesses
• Door to Door Geek: Recording Professional Podcasts in Open Source
• Ask the Geek: A Panel Discussion Moderated by Russ Wenner

Fiftonefifty discusses the utility byobu

byobu – A wrapper for screen and tmux
•Usage byobu-tmux [tmux options] , byobu-screen [screen options] , just byobu defailts to tmux
•The Caption line shows your open windows, and highlights the one upon which you are focused, and optionally displays your user name, host name, IP address, and a hint that there is a Menu available if you press F9.
•The Hard Status line consists of color coded output and symbols with configurable and dynamically updated facts, statistics, and information about the local system.
STATUS NOTIFICATIONS are fully documented in the linked reference

Key Bindings that I find moste useful
F2 Create a new window
F3 Move to the previous window
F4 Move to the next window
F5 Refresh all status notifications
F6 Detach from the session and logout
Shift-F6 Detach from the session, but do not logout




Sansa Clip Zip and Sansa Fuze running rockbox

I’ve been running rockbox on my Fuze since late 2010 (first time I /joined #rockbox on freenode was Fri Oct  1 2010.

Go to, locate your player make and model, download the rockbox manual for your player, read through the manual, download the install utility and you’ll get some basic themes. you can select other themes from

Rockbox on my devices supports sdhc cards up to 32GB along with internal storage. I used fdisk to partition the card and mkfs to put a vfat filesystem on the card.

Boot into the stock firmware and put the Sansa device into usb|msc mode, mount the device and run the installer. The default mode is mtp, and I have never tried to access either device in mtp mode, only usb|msc mode. The installer is a graphical application. The installer handles everything, all you need to know is where the device is mounted. The installer puts a bootloader and the rockbox firmware on the device. When you power on the device, you always have the option to boot into rockbox or boot into the stock firmware.

I got a Clip Zip as an emergency backup player: sooner or later, I expect the Fuze to fail (nothing electronic lasts forever).

Many additional features are available in rockbox compared with the stock firmware: file manipulation and listing, a database is created of all the files, so you can select what file to listen to by selecting a file from the file listing or selecting using the database listing.

The Fuze Clip Zip with rockbox has fewer features than the Fuze. The Fuze uses a wheel with center button (select) while the Clip Zip used a north-south-east-west selector plus center button. My muscle memory for navigating and selecting files or features, is better with the Fuze.

The Fuze Clip Zip uses the center select button for a lot more than the Fuze, and different actions are triggered by short, medium and long select presses.

Both devices use proprietary cables for data transfer and battery recharging. Battery life seems about the same for both devices: I’ll start an eight hour work shift with 100% battery and by the end of the shift, having listened for 5 or 6 hours, I’ll be at maybe 40%.

The Fuze sometimes resets when copying a file and I have to wait for the process to stop, unmount and remount the device. Once a month (or less often) my machine crashes and I have to do a hard reboot: maybe a bad cable, wrapped|folded too many times?

I’ve only listened to .mp3 or .ogg files on both devices. There may be some way to watch videos, but I’ve never tried.

There may be a way rockbox can increase the audio playback tempo per file, but I’ve not looked into doing that. (Increasing the playback without altering the voices so they sound like Mickey Mouse.)

5150 Talks about creating an IRC Channel
Registering a Freenode.Net IRC channel and setting up operators

• Establish your new Freenode channel
• Freeenode was originally set up to support development projects and that is still reflected in their mission statement.
• To register a channel, you must have a registered nick
• Channel  naming official (primary) channels start with a single hash.   Secondary, unofficial channel names start with two hashes.  Say we  wanted to create a sub channel to discuss the design of the web page, we  might call it ##LinuxLUGCastWordpress
• Check the availabilty of the the channel you want to register.  Freenode says to use /msg ChanServ info #MyNewChannel , but  that command never returned anything for me, even with channels I knew  existed. Do worry, ChanServ won’t let you register a channel name (case  insensitive) that already exits.
• All you have to do to create a channel is to join it /join #MyNewChannel   Note, you re automatically set as admin for this channel.  Of course,  if you don’t register the channel (or hold it open with a bot), it will  disappear as soon as all users leave.
• Now register your channel /msg ChanServ register #MyNewChannel
• Set yourself up as administrator (Operator, or op) for your channel
• But  I’m already an op since I created the channel, you say.  Not so much  I’m afraid.  Leave the channel and come back, see, you are no longer OP.
• You are not an OP but you are the Founder, which gives you right to make people, including youself, OPs
/msg ChanServ OP #MyNewChannel MyNick
• If you want to set up your fellow OPs at this point use /msg ChanServ OP #MyNewChannel OtherOpNick
• Set operator defaults for yourself and your fellow operators
• But  wait a minute, I’m still not an OP!  If you are using a GUI IRCmanager,  like XChat, if you right click on your name you will find a menu item  like “Operator Actions”, and under that “Give Ops” and “Take Ops”.  You  can elevate yourself here, and you can do the same for the others you  made OPs (though they won’t be able to do it for themselves yet).
• You  set operator defaults with the FLAGS command.  The +O arguement means  the user will always join the channel as an OP, +o joins them as a  regular user with the option to elevate themselves, i.e:
• You always want to join the channel as an OP, issue: /msg ChanServ FLAGS #MyNewChannel MyNick +O
• If you want the other OP you created to join a a regular user with the power to make themselves an OP, issue:  /msg ChanServ FLAGS #MyNewChannel OtherOpNick +o
