There is a very nice script for automating the setup of a chroot jail for ssh / scp / sftp on fuschlberger.net

Just run the script with no args to get find out its parameters.

I had to make some modifications to get it to run on Ubuntu Server though. Specifically, change these lines (at ~ line 406):
TMPFILE1=`mktemp` &> /dev/null || TMPFILE1="${HOME}/ldlist"; if [ -x ${TMPFILE1} ]; then mv ${TMPFILE1} ${TMPFILE1}.bak ; fi
TMPFILE2=`mktemp` &> /dev/null || TMPFILE2="${HOME}/ldlist2"; if [ -x ${TMPFILE2} ]; then mv ${TMPFILE2} ${TMPFILE2}.bak ; fi
to these lines:
#TMPFILE1=`mktemp` &> /dev/null ||
TMPFILE1="${HOME}/ldlist"; if [ -x ${TMPFILE1} ]; then mv ${TMPFILE1} ${TMPFILE1}.bak ; fi
#TMPFILE2=`mktemp` &> /dev/null ||
TMPFILE2="${HOME}/ldlist2"; if [ -x ${TMPFILE2} ]; then mv ${TMPFILE2} ${TMPFILE2}.bak ; fi
