SSH login disconnect with Operation not permitted [preauth] I have SSH server running on an Android phone under GNURoot app with image file for wheezy. The sshd -d on the phone says:

Server listening on port 2233

and after I try to login the connection established and then I get:

chroot(/var/run/sshd)" Operation not permitted [preauth] 
do_cleanup [preauth] 
do_cleanup 
Killing privsep child 18597

The ssh client on my computer says:

Read from socket failed: Connection reset by peer

Anybody has any idea what went wrong?
Use dropbear instead.

apt-get install dropbear

I cannot find any way to avoid chroot error, so I suggest you another ssh server. It works well. :-)
