I think editing /etc/services to renumber the telnet service would be a
mistake. Either just camp telnet on another service's port, or add
something like a "joetelnet" at a new port #.

I'm not sure what all uses /etc/services (other than inetd, obviously :-)
, but have the gut instinct that changing "well-defined" values to
non-standard ones can cause a problem. Or more accuratly, it might  cause
one a while in the future.

Nope, that's it. Your telnet will still be as (in)secure as before, just
external intruders won't know where to look for it.

Take care,
