Excuse me, I did a "ssh user@host" instead of "sftp user@host". That's
why it tried to open a tty.
So I tried again with SFTP and I got nothing more :'(

I didn't know that I can have different logging level in the sftp
process. thanks for the tip
I have tried and there is some information : sftp cannot allocate a tty !
The logs :
Starting session: forced-command (config) 'internal-sftp' on pts/11
for cpdp from 10.1.0.161 port 50336
debug2: fd 3 setting TCP_NODELAY
debug3: packet_set_tos: set IP_TOS 0x10
debug2: channel 0: rfd 9 isatty
debug2: fd 9 setting O_NONBLOCK
/dev/pts/11: No such file or directory
debug3: fd 7 is O_NONBLOCK
open /dev/tty failed - could not set controlling tty: No such file or
directory
looks like it requires having a duplicate environment inside the
chroot :-(
Is there a way to avoid /dev duplication ?
If not, does anyone know how to do it ?
Thanks,
Thierry

Adding some debug flags to your sshd_config Subsystem declaration might
elicit a little more information, e.g.
Subsystem sftp internal-sftp -l debug3
