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: 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 Use the command rm filename to remove large, unused files
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.
XWin-32 gives an error like this: ILLEGAL HOST KEY FOR zuma.eecs.uci.edu Remove SSH2\|key_??_zuma.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 zuma in them and delete. restart X-Win32
When I sign into zuma.eecs.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).
Cadence says my files are locked! How do I fix this?	Cadence locks files so that files are not edited by two independent copies of Cadence. However, sometimes lock files are not correctly removed. In this case you may get a message like "Couldn't get a write lock for..." If you are sure that your files are not opened in another instance of Cadence you can use the command rmcadencelock to delete the offending lock files.
Cadence crashed, I forgot to save, and I lost hours of work! What do I do?	Restart Cadence. Hopefully you will get a message like: Cellview (part1 layout) from lib (lab3) is saved in the panic file (/home/username/cadence/lab3/part1/layout/layout.cd-) To recover do: dbOpenPanicCellView("lab3" "part1" "layout") Just paste the last line into the bottom text input box of the ICFB window (the first window that appears). It should respond with some sort of cryptic success message. Then simply open that cellview and hopefully most of your work will be restored.
