+Can I advertise on NPCS?

Please read the information about advertising at

+How do I read a floppy disk in Unix?

Logon to a Unix Workstation:

rlogin to the workstation name (eg rlogin norma);
type "volcheck" to access the disk drive;
type cd /floppy/floppy0.

Standard unix commands (eg ls or pico) will now relate to the data on the disk. To eject: use the cd command to go to unix file space; type eject.

+How do I restore my .login .cshrc files (I've changed them and they don't work)?

You can restore the .login /.cshrc directories from the default ones.

At the unix prompt, enter the commands
cp /usr/local/share/etc/proto.cshrc .cshrc
cp /usr/local/share/etc/proto.login .login

You will then need to start a new unix session. NB: With this option, you will revert back to the default unix commands.

+Why can I not access UNIX via cdehost?

Three things to check:

  1. Do you have the right software installed ? On a networked NPCS machine go to Start / Durham Network / CDE - cdehost. You will then be prompted for your username and password. Other users may have to install the latest version of Hummingbird Exceed, which is available on the Durham Network folder CD-ROM, from the main ITS Helpdesk.
  2. Do you have an active Durham IT account and are you inputting the correct username and password when prompted ?
  3. Occasionally, users who have run out of space on their home or J: drives are unable to configure and use a CDE connection to UNIX. If you have recently run out of space on your UNIX / NPCS home drive, you will need to go to the main ITS Helpdesk where an advisor can talk you through restoring your CDE preference files.
