Running gogo6 Client on Mac OS X


1. Install Apple XCode if not installed yet, this comes with Snow Leopard installation DVD. For help see http://www.mactricksandtips.com/2010/02/installing-xcode.html

4. Retrieve the source archive from the Freenet6 download area for gogoCLIENT 1.2 Source Code (Linux/Unix/MacOS/BSD), at http://gogonet.gogo6.com/profile/gogoCLIENT , place it in a temporary directory, preferably /tmp because directory with spaces will fail

5. Go to the temporary directory in step 4 and decompress the file using this command :

$ tar -xvf gogoc-1_2-RELEASE.tar.gz

6. After decompressing go to the gogoc-tsp directory

7. Generate the gogoc executable by entering the following commands:

$ make all

$ make installdir=/usr/local/gogoc install

Note that superuser privileges may be needed above

9. Change dir to /usr/local/gogoc/bin

10. Enter the following to run :

$ sudo ./gogoc to execute

11. Check out http://ipv6.google.com and http://www.v6.facebook.com which will only work if you have a working IPv6 Public address. Also test the connection at www.test-ipv6.com

how to set a fat (vfat) disk on key label in ubuntu linux

reference : https://help.ubuntu.com/community/RenameUSBDrive

FAT16 and FAT32

These filesystems are most often found on USB thumb drives, flash cards (like for a camera or cell phone), and older external USB hard drives.
Check the current label

sudo mlabel -i  -s ::

ex:

     sudo mlabel -i /dev/sdb1 -s ::

Note that we're using the special "::" drive which allows us to specify the device descriptor on the command line; otherwise we'd have to edit ~/.mtoolsrc to assign a drive letter (see Option 2 under "Change the label").

Change the label

Option 1

After unmounting and checking the current label (above), use

sudo mlabel -i  ::

ex:

     sudo mlabel -i /dev/sdb1 ::my_external

Ignore the "Volume label is XYZ" output as this is the old label. Jump to the Verify the Change section below.
