daytime, i'm not sure on.
chargen, as it's name suggests, generates characters
echo, echos any characters it receives.
there have been some really fun denial of service attacks back in the
olden-days, caused by spoofing a tcp session and linking the echo and
chargen ports together =)
my whole builtin services section is commented out, so i don't worry about
it.
hope this helps.
