+Just as we did by creating the <c>check_nrpe</c> command, we can create a |
| 76 |
+command that executes a command remotely through a passwordless SSH connection. |
| 77 |
+We leave this up as an interesting exercise to the reader. |

+</p> |
| 83 |
+ |
| 84 |
+<ul> |
| 85 |
+ <li> |
| 86 |
+ Make sure the passwordless SSH connection is set up for a dedicated user |
| 87 |
+ (definitely not root) - most checks you want to execute do not need root |
| 88 |
+ privileges anyway |
| 89 |
+ </li> |
| 90 |
+ <li> |
| 91 |
+ Creating a passwordless SSH key can be accomplished with <c>ssh-keygen</c>, |
| 92 |
+ you install a key on the destination system by adding the public key to the |
| 93 |
+ <path>.ssh/authorized_keys</path> file |
