It's always the one you least expect:
Bash handles several filenames specially when they are
used in redirections, as described in the following table:
/dev/tcp/host/port
If host is a valid hostname or Internet
address, and port is an integer port number
or service name, bash attempts to open a TCP
connection to the corresponding socket.
/dev/udp/host/port
If host is a valid hostname or Internet
address, and port is an integer port number
or service name, bash attempts to open a UDP
connection to the corresponding socket.
(Sorry for the weird quoting, I already deleted Lluís's email, so I had to
wait for another reply to get on the thread.)
