your predicament reminds me I must say of a horror inflicted on
plebian UCD netsoc members such as myself. It's called rBash, the 'r'
standing for "restricted". That is an understatement.
On entering oen is graced with the following message:
This is rBash, a restricted UNIX shell. If you are at all intimidated by
command line interfaces, type "exit" now!
This shell has access to a few useful programs such as ls, df, du, chmod,
and a few compression utilities. Below is a full list of the commands
you can access:
cat chmod cp cut date df diskused echo
editor file finger gunzip gzip head helpme kill
ln ls mesg mkdir mv ps pwd
rm rmdir split stty tail tput uudecode
Hope you enjoy it!
To leave rBash at any stage type 'exit'.
the joys of it include:
gavinmcc at orca:~> echo $PATH
gavinmcc at orca:~> ls /usr/slocal/shell
ls: /usr/slocal/shell: Permission denied
gavinmcc at orca:~> /usr/bin/perl
rbash: /usr/bin/perl: restricted: cannot specify `/' in command names
gavinmcc at orca:~> SHELL=$SHELL:/usr/bin/
rbash: SHELL: readonly variable
basically, the idea of it is that you can do nothing at all. Now before I
get a defensive backlash from cadelor etc, I'm not trying to criticize it,
but be aware that if you're up against this kind of thing you're banging
you're head against a brick wall. I'd suggest asking to borrow an account
from someone on a decent lease line so you can quickly transfer files over
and do what you need to.
