Comment 1 Sergio Polini 2006-03-11 03:00:58 UTC
Sorry, I pressed "Commit" before writing my short description ;-)
I've added hplip and cups to my default runlevel, but when I start hp-toolbox or xsane they hang, and lpr <file> doen't print anything.
I thought that it was because my multifunction printer (HP PSC 1510) was powered down when I booted, but they didn't work even if I booted after my printer was powered on.
To get hp-toolbox, xsane, and print commands working I have to restart hplip.
There is an easy workaround: I've added

/etc/init.d/hplip restart

to /etc/conf.d/local.start, but it looks a bit ugly ;-)
Comment 2 Marcelo Goes (RETIRED) gentoo-dev 2006-03-11 10:08:52 UTC
Hmmm, I'm wondering if this is a service dependency issue.
Would you mind testing not having hplip in any runlevel and starting it after your system has finished booting?

Also, have you taken a look in cups's interface (http://localhost:631) - manage printers? Sometimes when I power down my printer and turn it on again I have to restart it manually.

It works, so I've done more ;-)
I've edited my /etc/conf.d/local.start and deleted the line
/etc/init.d/restart.
Then I've edited /etc/init.d/hplip and replaced

depend() {
       before cupsd
       after hotplug
       use net
}

with

depend() {
       after *
       use net
}

and it works!
Comment 4 Marcelo Goes (RETIRED) gentoo-dev 2006-03-11 14:33:04 UTC
Glad it works :-). Ideally, though, we should find what is borking it... I'll probably get my ass kicked if I add "after *" ;-). However, indeed it does not need to be started before cupsd.

Do you happen to remember which services were started after hplip before you made this modification?

You are right ;-) Removing hplip from all runlevels ad adding /etc/init.d/hplip start to /etc/conf.d/local.start is better. I'll do so, for now.

After a few experiments, I'm (nearly) sure that hplip doesn't work well for me because of... iptables!
If I remove iptables, there is no problem. But that's another matter... I think I should look better at my rules.
Comment 6 Marcelo Goes (RETIRED) gentoo-dev 2006-03-11 17:06:38 UTC
Maybe iptables is blocking ESTABLISHED connections (especially on port 631)?
If iptables is the culprit, I agree the problem is more likely to be with your rules than anything else.

Cups works well. Better: I can connect to localhost:631 and even print a test page, but scanimage and hp-toolbox hang.

I'ld agree with you. However, I can't understand why hplip works well when it is started _after_ iptables ;-)
I've attached a few lines from /var/log/message: when hplip is started before iptables, and when it is started after iptables.
Perhaps I should send them to HP developers ;-)
Comment 9 Marcelo Goes (RETIRED) gentoo-dev 2006-03-12 09:27:07 UTC
Yes, this looks like an upstream case for me...
Comment 10 Marcelo Goes (RETIRED) gentoo-dev 2006-03-18 10:07:38 UTC
Please, let upstream know about this. My iptables rules don't interfer with hplip functioning, so I am guessing this is a very specific case. Please reopen if you think I am mistaken.

Cheers
Comment 11 Sergio Polini 2006-03-18 13:58:16 UTC
I agree with you and I'll take your advice.
Thanks
