|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:
rm filenameto 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:
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.
See dos2unix above to fix
/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
|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
rmcadencelockto 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.
