However, the default tcpdump parameters result in a capture file where each
packet is truncated, because tcpdump, by default, only captures the first 68
bytes of each packet.
To ensure that you capture complete packets, use the following command:
tcpdump -i <interface> -s 1500 -w <some-file>
You will have to specify the correct interface and the name of a file to save

SETTING UP MYSQL MIR ROR
Server failures are unavoidable and can make you lose all your vital data
related to tracking of the units and in such a scenario it is most crucial to make
the service up and running as soon as possible. To keep your service running all
