By gracefully rebooting nodus, the problem was solved.

It (">") actually was the tcsh prompt, but any commands with the shared or dynamic link libraries looked unfunctional.

I could use
    cd /.../...
and
    echo *
to browse the directory tree. The main mounted file systems like /, /usr, /var, /cvs/cds/caltech looked fine.
I was afraid that the important library files were damaged.

I tried
    umountall
and
    mountall
in order to flush the file systems.
These should run even without the libraries as mount must properly work even before /usr is mounted.

They indeed did something to the system. Once I re-launch a new login shell, the prompt was still ">"
but now I could use most of the commands.

I have rebooted by usual sudo-ing and now the services on nodus are back to the functional state again.

# nodus was working in the evening at around 9pm. I even made an e-log entry about that.
# So I like to assume this is not directly related to the linux1 incident. Something else could have happened.
