Sun-managers:
I'm taking the liberty of posting a short followup to Tony Tran's
excellent summary about remote booting a sun. In his article, Tony

You can avoid the "double tilda" trap by defining an alternate escape
character for your rlogin session. We use "@":
# rlogin console_server -e@
Because we have a "modem-server" system to which most everbody must
rlogin in order to tip/cu to the outside world, we have moved
/usr/ucb/rlogin to /usr/lib and replaced it with the shell script
below. This is an ordinary executable shell script, it is NOT setuid
(/usr/lib/rlogin IS setuid root, just as when it was /usr/ucb/rlogin).
It's worked well for us; if anyone has suggestions, send email and I
will summarize.

# if user specifys escape char, don't use default
for arg
do
case "$arg" in
-e?) E="";;
esac
done
exec $R "$@" $E # exec real rlogin
