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,
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:
Select: Settings->Edit->Host Keys
Select any keys with zuma in them and delete.
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
/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
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.
