I have followed the instructions here, (and many many others) but can't seem to get this working. As soon as I add
Code:
Match User sshuser
       ChrootDirectory /chrootdir
       X11Forwarding no
       AllowTcpForwarding no
I get the errors below when I try to SSH in. I am running Centos 6. make_chroot_jail says I am missing a couple of libraries, but from what I have read they are 32bit, I am running 64. I just can't find anything useful on these errors.
Code:
sshd[22]: Accepted password for sshuser from 123.456.789.012 port 1234 ssh2
sshd[22]: pam_unix(sshd:session): session opened for user sshuser by (uid=0)
sshd[22]: User child is on pid 27
sshd[27]: Changed root directory to "/chrootdir"
sshd[27]: error: mm_receive_fd: no message header
sshd[27]: fatal: mm_pty_allocate: receive fds failed
sshd[27]: error: buffer_get_ret: trying to get more bytes 1 than in buffer 0
sshd[27]: error: buffer_get_char_ret: buffer_get_ret failed
sshd[27]: fatal: buffer_get_char: buffer error
sshd[22]: fatal: mm_request_receive: read: Connection reset by peer
sshd[22]: pam_unix(sshd:session): session closed for user sshuser
Any ideas out there?
 
What have you prepared in the chrootdir so far? A shell for the user to run, etc? Does the chroot environment you have prepared work using the chroot command?
