]$ traceroute 192.168.0.1

Once the other side of the communication responds successfully it is necessary to test the SSH connection.

This is accomplished by

In this command “username” is the name of the user who executes the current process. “192.168.0.1” is the

IP address of the machine we want to communicate with. The first time around, it will ask you if you wish to add

the remote host to a list of known_hosts, go ahead and say yes. After the successful completion of this test,

logout from the remote machine using the following command:

]$ exit

4.4 NTP configuration

The NTP configuration is necessary for the machines that perform the measurements to be synchronized in

date and time. This is done as follows:

1. The first resource to install in this section is NTP. To do this execute the following command:

]$ aptitude install ntp

2. Once the NTP tool has been installed, type the following command:

]$ vi /etc/ntp.conf

3. Include in this file the line:

server myntp.server.com

From this line, the part “myntp.server.com” corresponds to the URL of the NTP server that

HADES will use for synchronization. Change this parameter with the NTP resource that the

environment has.

4. After editing the file, save the changes.

5. To start the NTP service, execute the following command:

]$ /etc/init.d/ntp restart

6. To determine if NTP is properly synchronized use the command:

]$ ntpq
