[ubuntu-uk] File Transfers

[Paul Morgan-Roach]

Any traffic destined for the local network will route exclusively to
that network.  As mentioned previously if you are on 192.168.1.1/24
and you send a file to 192.168.1.10, then routing occurs on the local
machine.  A broadcast ARP packet is sent to establish the MAC address
of the machine and subsequently the port on the switch to send the
packet to...the only time any routing gets done is if the machine is
not on the local subnet (say for example sending a packet to 8.8.8.8),
whereby the packet would then be sent to the default gateway on the
network for routing.

Another thing worth adding is that SFTP and SCP are actually safe
methods of transport when sending data over the internet, as both are
encrypted protocols :)
