Subject:	Re: sftp ssh chroot

I solved my problem regarding "jailing" users in cygwin. If anyone is 
interested, the patch for linux works fine for cygwin. Here are the steps:
1) Download http://chrootssh.sourceforge.net/patches/osshChroot-3.5.diff
2) Go to http://www.openssh.org/portable.html and get the sourcefile
    openssh-3.5p1.tar.gz.
3) tar xzf openssh-3.5p1.tar.gz
    patch -p0 < osshChroot-3.5.diff
    cd openssh-3.5p1.tar.gz
    ./configure --prefix=/usr --sysconfdir=/etc --libexecdir=/usr/sbin
    (Be sure to check that configure script, I can't remember the exact
    command.)
    make
    make install
4) Now run ssh-host-config -y or however you would normally set it up.
5) Create a user with the shell script I wrote, or write your own.

#!/bin/sh
# add a caged ssh user
# usage sshuser username
# make a directory according to the username
if [ $1 ]
then
	mkdir /home/$1
	mkdir /home/$1/bin
	mkdir /home/$1/home
	mkdir /home/$1/usr
	mkdir /home/$1/usr/sbin
	mkdir /home/$1/tmp
	cp /bin/bash /home/$1/bin
	cp /bin/cp /home/$1/bin
	cp /bin/cygwin1.dll /home/$1/bin
	cp /bin/rm /home/$1/bin
	cp /bin/mv /home/$1/bin
	cp /bin/ls /home/$1/bin
	cp /bin/cygcrypto.dll /home/$1/bin
	cp /usr/sbin/sftp-server /home/$1/usr/sbin
	echo "Remember to change /home/$1 to"
	echo "/home/$1/./home in /etc/passwd"
else
	echo "Usage sshuser username"
fi

6) Modify the users directory in /etc/passwd file to be
    home/username/./home
7) Hope this helps, and sorry if someone already posted this although I
    wish I had seen it if they had cause it would have saved me a lot of
    trouble, although trouble can be a good thing when it's a learning
    experience! =)
