chroot sftp & batch it!

1) edit /etc/ssh/sshd_config:

Match User backup

ChrootDirectory /var/backup

X11Forwarding no

AllowTcpForwarding no

ForceCommand internal-sftp

2) # kill -HUP `cat /var/run/sshd.pid`

3) create the new user, generate key,  and set permissions:

# mkdir -p /home/backup/.ssh

# useradd backup

# ssh-keygen -t dsa 

# cp id_dsa.pub /home/backup/.ssh/authorized_keys

# mkdir -p /var/backup/dir1

# chown root:wheel /var/backup

# chmod 755 /var/backup

# chown backup /var/backup/dir1

3) edit a batch file, sftp_batch  for sftp:

cd dir1

put myfile

4) then, fireup sftp client for batch processing now!

# sftp -b sftp_batch backup@localhost
