Im writing a shell at the moment that chroots into a users home dir and then
runs only the sftp-server program ( which is in the uses home dir ).
Anyway, it wont work unless /dev/null is present in the chroot...
I am using execve to run sftp-server, and I am wondering if it has something
to do with stdout / stdin / stderr fd's being closed on execve?
Can anyone help me here?
Thanks,
Josh

Alternatively, might something like rssh be useful?
http://pizzashack.org/rssh/
This is a shell, designed to only allow scp/sftp/et al, but not allow
any sort of command execution in the traditional sense. It also supports
chroot.
The only small fly in the ointment, is that according to
http://pizzashack.org/rssh/platforms.shtml it doesn't work on *BSD, as
it requires the missing wordexp() function. However, the page dates back
to 2003, and I haven't the skills to check if this is still the case...
Don't know if this helps or not, but I thought I'd throw it into the mix :-)
