You'll want "$@" (with the quotes) on the end of the last line, not $*.  Or
if you use #!/bin/sh instead of bash, you'll want ${1+"$@"} for historical
reasons.

Otherwise, you'll get the wrong results when users pass quoted strings with
spaces in them as arguments to ssh.

"$@" is equivalent to "$1" "$2" "$3"... for however many arguments there are.
"$*" is equivalent to "$1 $2 $3..."
$* or $@ (unquoted) is equivalent to $1 $2 $3...
