| | 137 | === Time Synchronization === |
| | 138 | CORNET uses a dedicated NTP server to provide time synchronization between the nodes, but it is not enabled by default. To enable time synchronization, log into the node(s) and run the following command: |
| | 139 | |
| | 140 | {{{ |
| | 141 | # sudo ntpdate 192.168.1.103 |
| | 142 | }}} |
| | 143 | |
| | 144 | It may take up to a minute for the nodes to synchronize, depending on network congestion. To test if the nodes are synchronized, view the output of the following command - it should give a value within a second or two on each node (the difference should only be the amount of time between executing the command on each node): |
| | 145 | |
| | 146 | {{{ |
| | 147 | # date +%s |
| | 148 | }}} |
| | 149 | |
