I've found a few problems with cups

1) it wants system/volatile/cups, but /system/volatile doesn't exist.
   Works if created manually and restart cups/in-lpd and /scheduler.
   Either system/volatile should be created somehow after boot before
   cups starts, or cups should be patched to put that into /var/run/cups;
   but...

2) ... it wants /var/run/cups/, but that doesn't exist. Should be created
   when it installs.

3) It complains about a missing ColorManager:
   "The name org.freedesktop.ColorManager was not provided by any .service
   files" which relates to a missing gnome-colord manager (because it's
   mate here...), so it can't read icc-Profiles for the printer. Don't know
   if that affects color-printing somehow.

4) it opens network connections like hell (on a simple client):

ro sunts ~ # netstat -afinet | grep \.ipp | wc -l
     105

don't see any messages in regard to this problem, neither in messages,
syslog, cups/access_log or error_log

Hello!

I dont't see this problem here:

I did a pkg update a few minutes ago..


Problem 4 is generated by cups-browsed (avahi,dns/multicast active).
Found this:

/etc/init.d/cups-browsed is linked from several rc*.d/ directories
with S* and K* entries (as specified in package contents).
The script does not set pid for SunOS, so more than one cups-browsed is
started and not killed in run level transitions.
Adding SunOS to the pid discovery in the script leaves one cups-browsed.

This one still generates a loop of connections. The printing server is an
older cups, which is accomodated by setting

ServerName  myserver/version=1.1

in /etc/cups/client.conf. The server is spammed with these log entries:

access_log: hundreds of entries
imksunts - - [17/May/2023:11:05:40 -0100] "POST /admin/ HTTP/1.1" 403 0 - -

error_log: hundreds of corresponding entries
I [17/May/2023:11:05:48 -0100] cupsdAcceptClient: label=(null)

So I suspect that the connection to the old cups printing server
does not function totally correct anymore. Nevertheless, all
advertised printers are found and can be used.

The problems 1 and 2 have been fixed by the latest update.
