You can try reinstalling CUPS using the instructions above.

I already did it before postin'... (I'm a good and devoted forum user :wink: )

Nothing else?

Sorry. I wish I knew how to replicate this problem, but I can't. (Un)fortunately, my CUPS installs are all rock-solid.

Some command I can give to see why the server hangs?

Code: Select all

# ps | grep cups
 5830 root       0:00 /usr/sbin/cupsd -C /etc/cups/cupsd.conf
# /etc/init.d/cups status
cups: scheduler is running.
# /etc/init.d/cups restart
cups: restarted scheduler.
# cups-config --version
1.3.11
Sob... :(

Try this:

Stop CUPS with the command: /etc/init.d/cups stop

Delete these folders, if they exist

/var/cups
/var/log/cups
/var/run/cups
/var/spool/cups
/var/cache/cups

Restart CUPS with: /etc/init.d/cups start

Done, nothing changed...

Ok, it seems I can only try with a new save file :cry:

One thing:

since first reboot after my "waiting for localhost" problem, before X starts I can read this warning:

Code: Select all

WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/.
and here's /etc/modprobe.conf content:

Code: Select all

options parport_pc io=0x378 irq=7 dma=3
Is it related?

That message has been around for a while. What Puppy version are you using?

Wary 104 (the latest Release Candidate)

Moreover today I discovered I don't have the PDF printer anymore it used to work before I first tried adding my Samsung printer... sgrunt! :evil:

Are you installing from the PET or from the official Samsung installer?

I removed your pet now, anyway I re-factored it leaving only the ppd of my printer, to save some space.

Anyway with no save file loaded the pet worked and the printer printed.

With my current savefile instead, no matter what I install or delete, I can't get any CUPS webpage but the home... :cry:

mikeb wrote me a PM about double checking possible changes in file / folders permissions.
I gave a look but did not find anomalies.

Then I looked at cups conf file adding ErrorLog file and setting LogLevel to debug.

Code: Select all

The second last line reports the error, I checked binaries in /usr/lib/cups/cgi-bin/ but all have rwx,r-x,r-x permissions so I don't understand the Permission denied last message.

According to this error 22 is:

Code: Select all

#define EINVAL          22      /* Invalid argument */
Any tip?

I think that adding as a default the cups error log (in /var/log/cups/ like Ubuntu) in all puppies could help a lot not experienced users.

Run

Code: Select all

top
and find the cupsd process. What user owns it?

@neurino:
I was messing around with the Debian installer for another printer driver and ended up in exactly your situation. I eventually discovered that the installer had changed permissions on a bunch of other folders and that was causing the

Code: Select all

/usr/lib/cups/cgi-bin/admin.cgi: Permission denied
Check the following folders.

/usr
/usr/local
/usr/share
/usr/share/doc

Each one should have root:root ownership and 755 permissions.

For any one that's wrong, run

Code: Select all

chown root:root xxx
chmod 755 xxx

I installed Google Chrome from a deb package...

Like also mikeb suggested me I found this differences between original puppy sfs and current savefile:

but no matter I can restore ownership and permissions things does not change and after every reboot I get ownerships and permission restored like above!

I used

Code: Select all

find / -type d ! -perm 755
to find out possible anomalies but just these 2 are cups-related:

Code: Select all

/etc/cups/ssl
/etc/cups-old/ssl
others are about themes, python etc...[/b]

The root:nobody ownerships are fine. CUPS wants them that way. Did you also check the folders I listed above?
