I'm following instructions about Installing and setting TFTPD in Ubuntu. It asks to
Create /etc/xinetd.d/tftp and put this entry:
service tftp { protocol = udp port = 69 socket_type = dgram wait = yes user = nobody server = /usr/sbin/in.tftpd server_args = /tftpboot disable = no }
What does it mean to create? Is there any command I need to type? And "put this entry" - it means to type in one line all the lines above? I don't know Linux & I need your help please.
