How to login to Linux at DCU
  1. reboot
  2. possibly reboot twice
  3. choose openSUSE distribution of Linux
  4. this uses GNOME GUI

  5. Change password:
    • passwd
    • Control Center - Change Password
    • Warning - This will not change your password for other DCU systems. (Novell, Moodle, etc.) As a result, and to keep admin simple, the sysadmins recommend not changing your password unless necessary.

  6. Automatic updates will apparently be run automatically for you. You can apparently close and ignore all messages about them.
  7. For admin problems contact Gary Conway
  8. If logged off, to shut down: press Power button

Remote access to DCU Linux (from home and from Windows)

  1. Remote command-line:
    • protocol is ssh
    • sample Windows client: PuTTY
    • ssh student.computing.dcu.ie
    • Note: Copy-and-paste is a bit cryptic on PuTTY
      • Copy - Select text
      • Paste - Right-click

  2. Remote read-write file system:
    • protocol is sftp
    • sample Windows client: WinSCP
    • alternative Windows client: WebDrive
    • sftp to student.computing.dcu.ie

  3. All postgrads (including my GDF class) have remote ssh and sftp enabled automatically.
  4. Some undergrads (including my EC class) have remote ssh and sftp enabled automatically.

  5. CA help on ssh

  6. Remote and Network Computing

USB key

To transfer files to/from USB key:


Bug - openSUSE and USB keys

I found that in copying from USB key to openSUSE, some file names got converted to lower case.
This meant that scripts now broke. This is very BAD.
Bizarrely, some were converted to lower case but not all.
I can replicate the following behaviour. See if you can replicate this and let me know.

  1. I took files with names in all uppercase like DSCF0323.JPG and copied them in Windows onto a FAT32 USB key.
    When opened on openSUSE this is read as "Filesystem type: msdos" and the filenames are changed to lower case: dscf0323.jpg

  2. The following filenames however are not altered: 
    DSCF0323.crop.JPG   unchanged (remains mixed case)
DSCF0323.lores.jpg  unchanged (remains mixed case)
file.jpg            unchanged
