Back at JSI

De-ja-vu...   I'm back at JSI.  :)

Another new job

Started 8 months ago.  Learning new things.  Went from Windows desktop support to Linux/Unix support.  Got a bit rusty on my Linux...  Have to learn quick.

New tool to keep handy = Gparted
      Created a bootable disk for use in partitioning hard drives.

Also learned that you can rename the .gconf and .gconfd directories from your Linux /home/username directory to get back the default Gnome environment.

I am the only one who has ever looked at my blog.  That's okay. Nothing here for anyone else anyway.

LINUX GPG and SHRED

GPG:


gpg -c <filename>   (encrypts file after prompting for password)
gpg <filename>   (opens file after prompting for password)


gpg --list-keys  (shows keys on system)
gpg --export -a user@localhost >file.asc  (exports a public key to a file.asc (e-mail@address listed in --list-keys query))
gpg --export-secret-keys -a user@localhost >file.asc  (exports secret keys to a file (that way they can be imported into another computer for decryption functions)


gpg --list-secret-keys
gpg --import <filename.asc>


SHRED:


shred -u -v <filename>   ( -u = truncate/remove file after shredding, -v = verbose )
