Help with CUPS reconfiguration

[Stan-18]

I am trying to reconfigure a bunch of machine to acomodate new domain
names. One of these machines is a fairly old FreeBSD machine (6.3). We have
done a search through all the files of these machines looking for
references to the old domain name. One of these is in /etc/printcap/
/etc/printcap has a comment in it that says it is auto generated by cops.
It refers to /usr/local/etc/cups/printers.conf as the source file.
However, this file does not have a reference to the old domain. My guess is
that this is picked up automatically from the machine name, when it is
built.

Therein lies the issue. I cant connect remotely port 631 on this machine as
the certificate is no longer valid, as the domain has changed. When I
go to the machine an try to connect to localhost:631, it gets connected,
but no combination of username password works.

How can I force cups to reconfigure?

Normally, a browser will let you proceed if you give it the correct
instructions.

root should work.

OK, but it doesn't.

I agree, it _should_ but as I stated, it _does_ not.

OK, I read that. It tells me how to configure cups, but as far as I can
tell, it does not tell me how to get cups to regenerate /etc/printcap,
which is what I need to do.

I have very few experience with CUPS (prefer apsfilter or PS),
but as far as I understood, the printcap file is altered
every time a printer is changed. So when you remove the
existing printer and create it again, all files should be
regenerated, both the /etc/printcap file as well as the
files in the /usr/local/etc/cups subtree.

Deleting and recreating still sounds like the "Windows"
way of doing things, but due to my impression that CUPS
is designed in a way that it appeals this special kind
of users' expectations, this may be the only way to achieve
your goal.

I agree with everthing you said.

The question I am sking, though, is "How can I modify the CUPS
configuration, without using the web based interface (which is not working,
in such a manner that the /etc/printcap file gets rebuilt.

The problem is that hte web interface seems to be a very
integrated part of the CUPS configuration which isn't intended
to be "not used". An option would maybe be to rewrite the
files in /usr/local/etc/cups as well as /etc/printcap
manually to reflect the desired changes, but I am not sure
that this will be sufficient - maybe there are other files
that are touched by automated processes during the printer
installation / reconfiguration through the web interface...

I think the only important parts in /etc/printcap are those
that reference to the printer filter and those that set some
specific values (resolution etc.); everything else is kept
in the CUPS files, and both places of settings should contain
the same individual data (e. g. same spool dir reference).

If you could take the following example as a starting point
and correct the settings manually so they show the same settings
as what you already have configured in CUPS.

        Laserjet|ljet4d;r=600x600;q=high;c=full;p=a4;m=auto:\
            :lp=/dev/lpt0:\
            :if=/usr/local/etc/apsfilter/basedir/bin/apsfilter:\
            :sd=/var/spool/lpd/Laserjet:\
            :lf=/var/spool/lpd/Laserjet/log:\
            :af=/var/spool/lpd/Laserjet/acct:\
            :mx#0:\
            :sh:

I'm not sure if cap_mkdb has to be run for /etc/printcap.

If you're using a network attached printer, a reference to its
name (known through /etc/hosts mechanism) should be okay.
