The DragonFly BSD team has announced the removal of the remote commands from their operating system. These commands, while they were useful in older versions of Unix, have generally been replaced by more secure utilities such as OpenSSH. "The commands rcp(1), rlogin(1), rlogind(1), rsh(1) and rshd(1) have been removed from DragonFly. There's a net/bsdrcmds port if you still need them. Though I imagine/hope ssh is filling the void for everyone."
