Ideas for the Cincinnati Linux Users Group From meeting 7-27-13

I. Possible interactions with other groups:
a) Python Group in Cincinnati, have members of their group give lectures to Clug, have a joint meeting from time to time
b) University of Cincinnati Linux group, have members of their group give lectures to Clug, have a joint meeting from time to time

interact via special interest groups

Need: Point of contact for discussions
II. Special Interest Groups:
a) Linux Certification Group
1. Comprised of folks who would like to become certified linux administrators, software experts or other.
2. Lay-out certification requirements and materials/study/information needs
3. Develop timelines and milestone events
4. Get the work done—
b) Vulnerability studies group
1. Folks interested in IT security, Current tools for breaching computer security and how they work
2. Choose various available tools to study; obtain source code; ask questions

II. Desired Presentations:
a) New presentation on how to set up MYTH TV
1. Includes general discussion on how the program works and general hardware discussion to include problem areas and insights
2. Includes one “set-up for Dummies”–i.e. This is the specific hardware, software and set-up used and it works.
b) How to set up a web server on Raspberry Pi

c)How to set up and use Amazon cloud/web services

d) Raspberry PI/Arduino Robot how it was done and details

III. Meeting Format:
1) Start meeting with introductions and possible with a linux question of some sort

2) Always have a time to “Solve the Problem” or “Answer the Question”

IV: Other: Community Involvement*

a) Talk with the library we meet in about having a linux install meeting
1. Talk with vendors, refurbishers, schools, businesses about free computers for distribution to the community
b) Talk with churches, schools, etc. about having a linux install time
* The first contacts/viable places to help folks with linux will be the first one we do. In CLUG each member is “the leadership”.

Changing the mount point of a partition

Hi CLUG,

I have an external backup drive. The partition that has my Linux backup files (via rsync) is recognised as

43a15d01-9f3f-4069-bdab-106832d54ff0/

when I plug my removable drive into a usb port on my computer. I tried to rename the partition. This is what I get:

mv 43a15d01-9f3f-4069-bdab-106832d54ff0/ backup/

mv: cannot move `43a15d01-9f3f-4069-bdab-106832d54ff0/' to `backup/': Device or resource busy

I seem to have a catch 22. I can’t rename the partition without plugging it in to my laptop and mounting it.

any ideas?

thanks

Bill

The number you’re seeing is a UUID, or Universally Unique IDentifier, it’s a number that is derived from a number of things, some of which are the date, the MAC address of the machine, and the local random number generator.
The simplest way to rename a filesystem is usually to use gparted (Gnu Partition Editor). First, make sure that the partition you want to rename is plugged in and visible, then issue the command in a terminal.

steve@NV78:~$ sudo mount
[sudo] password for steve:
/dev/sda1 on / type ext4 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)

none on /sys/fs/fuse/connections type fusectl (rw)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev)

gvfs-fuse-daemon on /root/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev)
/dev/sdb1 on /media/6828-CB13 type vfat (rw,nosuid,nodev,uid=1001,gid=1001,shortname=mixed,dmask=0077,utf8=1,showexec,flush,uhelper=udisks)

Just for the sake of argument, let’s say I wanted to rename the SD card from 6828-CB13 to Camera and it is formatted as vfat (last line in the output above), I’d issue:

steve@NV78:~$ sudo gparted

First, make certain that you have selected the correct device (/dev/sdb1 in the upper right corner of gparted), and that it is unmounted (right click on the device in the lower half of gparted). Then, change the label by right clicking the device and selecting Label in the pop-up menu. Finally, make the changes permanent by clicking the green ‘Apply’ checkmark button (upper center), and you should be golden!
