I’m using QNX 6.5 and my assignment is to get sftp working with the ChrootDirectory directive. I’m wondering if anyone else had been successful doing this. I’ve overcome one challenge already. sshd requires a pipe, but in a chroot jail, there is no /dev/pipe device. The solution was to start pipe in the same chroot jail from a program running as root.
Now I can login and have some functionality, for example, if there’s a file xyz in my directory I can do this:
sftp> get /xyz
or if there is a directory abc I can do this
sftp> ls /abc
However a lot of stuff doesn’t work. For example, If my chroot jail is /usr/test then
sftp> pwd
gives
/usr/test
which is wrong, it should be /
If I do this:
sftp> ls
I get an error that /usr/test doesn’t exist.
And finally if I try
sftp> cd /abc
I get an error
Couldn’t stat remote file: No such file or directory
Clearly something is broken. Can anyone help?
