what do chargen, echo, time, and daytime services do?

[Stanley Yee]

I'm optimizing my xinetd and ran found chargen, echo, time, and daytime
services.  Anyone know what these things do and the pros and cons of
removing them? Thanks!

Only me,
Stanley Yee

These instructions sound rather convoluted.  Why would this individual
need to boot from an installation CD just to edit a file?  I assume one
needs root priviledges to edit /etc/innitab, but wouldn't it be alot
easier to open a console, then su to root, then invoke a word processor
and open the file with it?  Or invoke MC from that root console, navigate
to the file using it, then use MC's editor to edit the runlevel argument?
Please clarify on the need to do the editing from other bootable media.

Thanks, James

Chargen simply puts characters onto the network.  It's most often used
for testing network connections.  Rarely does anyone need this service.

Echo simply echoes whatever it receives on the network.  Again, good for
testing netowkr connections but not very useful for most people.

I think that time will send the unix time (sec since 1970) to whatever
connections it receives.  I'm not really certain about this one.

Daytime will send a human readable string containing the current time,
such as "19 MAY 2003 20:02:05 EDT".

None of these services are going to cause you much grief if you disable
them (of course this is only my best guess).
