[Samba] Re: [Samba] After some print jobs, samba server doesn´t accept conections.

[Joel Hammer]

Are the clients linux/unix clients or windows clients? If they are windows
clients, I have no idea. But, if they are linux/unix clients:

This sounds like an lprng problem. I forget the cure.

Try sending numerous print jobs from the samba server. If the same problem
occurs, check out the lprng documentation.

Here is man lpd.conf from my redhat 7.1 box.

originate_port (default: "721 731") A range of port numbers to originate
requests from.  When sending service  requests, the software will try
to open and bind to these ports to originate a request to a server.
If no port is given,  or  all of  the requested  ports  are unavailable
or cannot be bound to, then a normal use port is requested.  Note that
on UNIX systems, if a port in the range 0-1023 is requested the EUID of
the process must be  root  for  the  request to be granted.  Note that
RFC1179 specifies that requests must originate from ports in the range
721-731.

This says that only root can use the ports outside of 721-731.
