samba - Apr 2002 - After some print jobs, samba server doesn´t accept conections.

I have RH 7.2, with Samba 2.2.1a, and LPRng printing system. I have two
printers, HP DeskJet 1220C and HP LaserJet 5.

When a user send many jobs to the printer after a short period of time the
server sends a message that the server is not accesible or is not connected
to the network, but any other user can do it, again, after some jobs sent to
the printer the server doesn?t accept any connection from that client.

I read the FAQ of LPRng, and it says that you must change the number of
ports in your lpd.conf file, but it has the correct number of ports.

==================obtained from www.lprng.org ============================
SOLUTION:

It appears that most RFC1179 implementations do not check for the exact port
range 721-731, but only that the connection
originates from a reserved port, i.e. - in the range 1-1023. You can extend
the range of ports used by LPRng by changing the

    originate_port=721 731

value in the defaults (LPRng/src/common/defaults.c) file or in the lpd.conf
file. I recommend the following: 

    originate_port=512 1022 <--- I have this numbers.
=======================================================================
What could be my problem??

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.

There may be a limit on how many jobs a windows client can sent at one time,
too.
I am not quite sure of what you are seeing on your windows clients. Are all
the clients locked out from using the printing service, not just the client
sending the large number of jobs? I thought your original post said only the
client sending the large number of jobs was locked out. Are only printing
connections being refused?

If all the clients are having problems if only one client is sending jobs,
then this really sounds like an lprng problem or a samba problem.
max mux might be of interest. 
max mux (G)
This  option  controls  the maximum number of outstanding simultaneous
SMB operations that Samba tells the client it will allow. You should
never need to set this  parameter.
  Default: max mux = 50

When faced by this sort of odd problem, there are a number of places to
look for info:
1. The samba log. 
2. The log for your printer.
3. /var/log/messages
4. smbstatus
5. lpq 
6. tcpdump (last, desperate hope.)
