    Solutions to Common Problems:

    Symptom Solution
    I keep seeing "Over Quota" messages. What does that mean and what do I do about it. It means you've used all your allocated disk space. To save more files, you'll need to remove some.

    Things to check:

  • Netscape or Mozilla disk cache
  • Make sure you empty your trash when you throw files away
  • Remove old files by ftp'ing them to another computer then throwing them away
    • I'm trying to reduce my quota usage but I can't get it to go down even though I've thrown a lot of files in the trash. Just like PC's, the files don't disappear when you throw them in the trash. You have to empty the trash to get them removed from your quota usage. If you've logged in using SSH, rm the file.
    How do I flush my Netscape or Mozilla disk cache? Netscape 7:
    Edit -> Preferences -> Advanced -> Cache -> Clear Disk Cache
    I try to log in on a Sun Ray terminal but the screen goes black and then goes back to the login screen. It's likely that you are over quota and need to remove some files before you can log in.

    You'll have select the Command Line or Fail Safe option in the login window or SSH in from another computer to fix the problem.

    Please see Useful Commands for more help.

    XWin-32 gives an error like this:

    ILLEGAL HOST KEY FOR newport.eecs.uci.edu Remove SSH2|key_??_newport.eecs.uci.edu.pub and try again if you think that this is normal.

    		This should fix the problem:
  • Exit X-Win32
  • Start F-Secure
  • Select: Settings->Edit->Host Keys
  • Select any keys with newport in them and delete.
  • restart X-Win32
    • When I sign into newport.ece.uci.edu I don't get my usual prompt My session just has a >

    When I try to run a command like 'ls', it says command not found

    		The problem is probably because you either edited your .cshrc file and made mistake or deleted your .cshrc file.

  • If you edited the file with a PC editor it probably added bad control characters in the file (^M's). Please use a unix editor to edit these files.
    See dos2unix above to fix

  • If you edited the file, back out the last changes you made, especially any that have to do with the path

  • If you deleted the file, you can copy a clean one from /dcs/skel/.cshrc:
    /bin/cp .cshrc .cshrc.broken
    /bin/cp /dcs/skel/.cshrc . (that's a dot)

    Always make a backup of the file before you edit it.

    • I keep getting the message:

    You already have a magic process running
    Only one magic process may be run at a time

    		You may one run one magic process because it takes up too much system resources. If you've forgotten to exit the process, you can identify it using the 'ps' command and kill it using the 'kill' command (see Useful Commands above).
    I have a desktop that looks funny and I can't log out

    		 You probably don't have the CDE desktop. If you have a xterm window, run the command 'kill -9 -1' to kill your session.

    When you log in again, after you type your login name and press enter but before you type your password, select Options -> Session -> Common Desktop Environment (CDE).
