We require a  port reader services program running  a port assignment in the 9000-11000 range for on your Linux box. Can we get a perl script for this service?

Not entirely sure I understand what you want.  You want a server daemon that will listen on a port between 9000-11000?  Why not just one port?  Also, does this have to be running at all times like a daemon or can it be ran when a connection is made?  If a daemon, I am not sure as I haven't done that before.  I don't see why it isn't, just don't know how.  As for the second, the easiest is to create a new entry for the Xinetd service and have that use a port assignment.

however could use more clarification on what your trying to do.

i mean any port between 9000-11000, yes, has to run all the time. daemon...we want a tcp socket (i think for print jobs)  to be open on our server which will take a stream of data and save it as a file on our server (also called a virtual printer..)

what type of file format is it suppose to be saved in?  Just curious, because if you use samba, it can share a virtual printer from there that will convert documents to a pdf.

just trying to think of other options so you don't have to re-invent the wheel if at all possible (besides I don't know how to program a always running daemon in perl so am trying to think of other ways I do know how to do)

well buddy i think we will  have to reinvent 'cause we are receiving it from a VPS/DRS printing system... we will get a text format data. and we just have to save it in a file...we will have to create a tcp socket.

found this page when googling and it looks fairly good (to me anyway)

does this put you in the right direction?

then probably make the port a command line argument when starting it, then create another script that starts all the daemon's and loops thru all the ports you need to open.
