Hm, then lets simply wait for someone who can supply the necessary
information then?

1234 .

So, I should try the same without specifying a port?

Then I hope that someone reading this list can provide a definite answer :)

Well, first of all, that was the way described in my "Solaris 8
Administrators Guide" book.
What is more, only changing two files and restarting inetd was necessary.
Moreover, that way, it would be one process less which is running
so I figured, doing it this way might save some system ressources.
Finally, there is no need to write any additional shell scripts.
