 +==== SSH ==== 
 +  * Install the OpenSSH server  
 +    * The OpenSSH client is installed by default (so you can ssh into other computers). The OpenSSH server is required for connection into this machine (e.g., auto backup from the lab server). Use ''sudo apt-get install openssh-server'' to install. 
 +  * SSH security 
 +     * Once the OpenSSH server is installed, it is important to increase the security 
 +     * see more info here: [[computers:ssh_security|SSH security]] 
 +     * Minimally, update the ''/etc/hosts.deny'' and ''/etc/hosts.allow'' files to allow only the IPs that should have access 
 +     * Install Fail2ban: ''sudo apt-get install fail2ban''

 +if necessary, format the new disk

 + 
 +To mount a disk automatically during start-up, find the UUID using ''blkid'' and add the disk to ''/etc/fstab'' 
 +<code> 
 +$ blkid -s UUID

 +$ cat /etc/fstab 
 +# /etc/fstab: static file system information. 
 +# 
 +# Use 'blkid' to print the universally unique identifier for a 
 +# device; this may be used with UUID= as a more robust way to name devices 
 +# that works even if disks are added and removed. See fstab(5).
