[Samba] How the program spoolss works ?

Fri Feb 7 14:40:39 UTC 2020

hello,

I had already tried to follow your url . I modify my smb.conf with only only 2 commandes rpc_server: spoolss = external and rpc_daemon: spoolssd = fork
but with no succes . 

I change  my smb.conf as yours but i have always my errors. 

If i put 

  rpc_server:spoolss = external
    rpc_daemon:spoolssd = fork
    # Most are default, i just find it handy to see it on my print server.
    spoolss:architecture = Windows x64
    spoolssd:prefork_min_children = 5           # Minimum number of child processes
    spoolssd:prefork_max_children = 25          # Maximum number of child processes
    spoolssd:prefork_spawn_rate = 5             # Start (fork) x new childs if one connection comes in (up to prefork_max_children)
    spoolssd:prefork_max_allowed_clients = 100  # Number of clients, a child process should be responsible for
    spoolssd:prefork_child_min_life = 60    

or i don't put it - I have the same logs .. I don't understand .
yet i see smbd and the subprocess with the command ps axf 

after rowland modifications and yours , i put my new smb.conf. I have problably forget something  

thanks for your help

So after Rowland's adviced changes.

I use this part for printing.
https://wiki.samba.org/index.php/Setting_up_Samba_as_a_Print_Server

I added this to the smb.conf for my print server (note, i use a member server). 
I use cups - raw so my clients generate the print job. 

##### PRINT SERVER PART #######
    #enable asu support = yes

    ## Enabling spoolssd
    rpc_server:spoolss = external
    rpc_daemon:spoolssd = fork
    # Most are default, i just find it handy to see it on my print server.
    spoolss:architecture = Windows x64
    spoolssd:prefork_min_children = 5           # Minimum number of child processes
    spoolssd:prefork_max_children = 25          # Maximum number of child processes
    spoolssd:prefork_spawn_rate = 5             # Start (fork) x new childs if one connection comes in (up to prefork_max_children)
    spoolssd:prefork_max_allowed_clients = 100  # Number of clients, a child process should be responsible for
    spoolssd:prefork_child_min_life = 60        # Minimum lifetime of a child process (60 seconds
                                                # is the minimum, even a lower value has been configured)
    load printers = yes

# Windows clients look for this share name as a source of downloadable
# printer drivers
[print$]
   comment = Printer Drivers
   path = /var/lib/samba/printers
   acl_xattr:ignore system acl = yes
   browseable = yes
   writable = yes
   guest ok = no
# Uncomment to allow remote administration of Windows print drivers.
# You may need to replace 'lpadmin' with the name of the group your
# admin users are members of.
# Please note that you also need to set appropriate Unix permissions
# to the drivers directory for these users to have write rights in it
   write list = root, administrator, @"Domain Admins", @lpadmin, @"Print Operators"

[printers]
   comment = All Printers
   path = /var/spool/samba
   acl_xattr:ignore system acl = yes
   browseable = yes
   printable = yes
   printing = CUPS

Do note.. 
My setup only asumes windows clients so i set : acl_xattr:ignore system acl = yes 
And then i configure the shares exact the same as on a windows server. 
Once configure, DONT change/use chmod/setfacl of anything else. 
Then you most probely have to re-configure the shares again.
