In CA labs

You can ignore all messages about them.
- For admin problems contact Linux Administrator
It is not
necessary to change your password.
Changing your password for Linux
will not change it for other DCU systems (Windows login, Loop)
and experience has shown this leads to confusion and work for the sysadmins.
- If you must change your password:
Control Center - Edit Personal Information - Change Password
Access from home and from Windows.
- Remote command-line:
- protocol is ssh
- Remote read-write file system:
- protocol is sftp
- sftp to student.computing.dcu.ie
- Most DCU classes have remote ssh and sftp enabled automatically.
If you do not, tell me.
Here is how I do remote access to DCU Linux from my Windows laptop in lectures.|
There are many ways of doing this.
This way involves buying software.
- ssh with
(because I like it)
- sftp with WebDrive
(because it makes remote site a drive letter in Windows)
- Then just use Windows programs like
to edit files on the X: drive.
WebDrive making remote Unix and Linux systems into drives on your Windows machine.

- PuTTY download
- PuTTY FAQ
- Right-click bar - Change settings - Colors - Use system colors
- Change settings - Appearance - Change font
is strange on PuTTY:
- Copy - Select text
- Paste - Right-click (or Shift-Insert)
- Right-click Paste is rather dangerous, so you can change this:
- Window - Selection - Right brings up menu

- X11 Forwarding
Linux GUI programs run remotely on Linux but appear on local desktop.
- Windows X11 Forwarding:
- Run Xming
- PuTTY - Connection - SSH - X11 - Enable X11 Forwarding - login
- You can now launch a GUI program like gedit
- Web browser
works with X11 Forwarding
- Q. Why would you ever run the web browser on remote machine not the local machine?
- X11 Forwarding is possible on Mac too.
alternatives to Xming
- Remote desktop protocols
- Remote Desktop Protocol (Windows).
View remote Windows desktop on local Windows.

Bug (maybe fixed) - 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.
Bizarrely, some were converted to lower case but not all.
- 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
- The following filenames however are not altered:
DSCF0323.crop.JPG unchanged (remains mixed case)
DSCF0323.lores.jpg unchanged (remains mixed case)
Use your own Unix/Linux shell
