Hmm.  On my printer box that socket is 770 and I can print fine so
I think changing the perms might just be masking the issue you are
having.

Usually printer daemon problems are due to ownership/group issues
in /var/spool/lpd or /var/spool/output, or path specifications
that are not accessible by group 'daemon'.

In particular the lock file in /var/spool/output has to be 664
and the lock and status files in /var/spool/output/lpd have to be
664.  And the group has to be 'daemon'.

I'm getting the same exact problem as described when printing from a
regular user:

le...@alcyone: {102} lpq
alcyone: Warning: no daemon present
Rank   Owner  Job  Files Total Size
1stlette 618  (standard input)  697 bytes

no entries

I've just upgraded from 1.6 to 2.4, and I have this problem since. When
I'm printing from a user that is not in the 'wheel' group, I'm getting this:

le...@alcyone: {101} cat .cshrc | lp
lpr: Unable to connect to /var/run/printer: Permission denied
lpr: Check to see if the master 'lpd' process is running.
jobs queued, but cannot start daemon.

I have a printer named impgal01, and my directories permissions are very
similar to the one you show:

alcyone# ls -la /var/spool/lpd

drwxr-xr-x   2 root  daemon  512 Dec  4  2007 .

drwxr-xr-x  2 root  daemon  512 Mar 13 12:39 .
drwxr-xr-x  4 root  daemon  512 Dec  5  2007 ..

It really seems that something changed in lpd between 1.6 and 2.4. I'll
have no choice than to chmod /var/run/printer if I want users to print.

Re: Printer Daemon (Update)

[Tim Darby]

I'm seeing this exact problem on a 2.8.3 system.  I've done the following
troubleshooting steps:

- Verified that I'm using the lpr that came with the system
- Verified that my spool directory permissions are all correct

When I print locally with lpr as root or as a user in the wheel group, it
works fine.  If I try to print as an unprivileged user, it fails.  I noticed
that changing permissions on the socket file /var/run/printer to 777 solves
the problem, but that doesn't seem like a good answer.  I see that lpr is
suid and in lpr/common_source/startdaemon.c, before it tries to connect to
the socket, it does a seteuid() to root, but I don't know what happens after
that.  Anyone have any insights into this?

Re: Printer Daemon (Update)

Hmm.

apollo:/usr/src/sys/vfs/hammer> ls -la /usr/bin/lpr
-r-sr-sr-x  1 root  daemon  26588 Oct 21 21:46 /usr/bin/lpr

Make sure lpr is suid & sgid root:daemon.  I am assuming your
filesystems aren't being mounted with the nosuid or nosgid mount
flags as well.

If lpr can't access the socket it kinda sounds like it isn't running
sgid.

Re: Printer Daemon (Update)

[Tim Darby]

Yep, lpr looks right:

-r-sr-sr-x  1 root  daemon  26588 Nov 21 12:56 /usr/bin/lpr

and I haven't put nosuid or nosgid on my filesystems.  It's very puzzling.

My /var/spool is a hammer pfs, as created by the installer defaults.  This
feels like it has to be a permissions problem somewhere, but I haven't had

What is the output of:

ls -al /var/run/printer
id

What are the exact error messages you are receiving?

Thanks,
Joe

Re: Printer Daemon (Update)

[Tim Darby]

Here's the output:

srwxrwx---  1 root  wheel  0 Nov 21 23:14 /var/run/printer
uid=1001(tim) gid=1001(tim) groups=1001(tim)

and this is the error I'm seeing:

> /usr/bin/lpr -PHPLaser /home/tim/test
lpr: Unable to connect to /var/run/printer: Permission denied
lpr: Check to see if the master 'lpd' process is running.
jobs queued, but cannot start daemon.

Note that the lpd daemon is definitely running, so that's not an issue.  I
think that error means that it can't fork the daemon to handle this job.
 Also, here's what I see in the spool dir:

> ls -la /var/spool/output/lpd

drwxr-xr-x  1 rootdaemon   0 Nov 21 23:17 .
drwxr-xr-x  1 rootdaemon   0 Nov 21 22:52 ..

That job will stay in the queue forever until I restart the queue or "bump"
it by printing something as root.

Thanks,

Tim

What is the output from:   ls -ld /var/run
And maybe: ls -ld /var
although I'd be pretty surprised if /var was the problem.

Seems strange that several people are seeing this.  I can't
imagine what's going on, so all I can do is make some wild
guesses at it.

I agree; this is really bizarre-o.

One other data point, fwiw:  This machine, I'm pretty sure, started out with
a fresh install of DF 2.6, which was then upgraded via source to 2.8 and
this is the first time I've used it to print.  If I can find a spare
machine, I'll try a fresh install.  Would a vkernel make a good test?

Thanks,
Tim

This issue is in HEAD as well.  I'm working on a fix.  In the mean
time you can add yourself to the wheel group to get printing working.

Please try the attached patch.  There's a slight possibility of a
panic on boot so make a backup copy of /boot/kernel before
installkernel.

Make sure to remove yourself from wheel if you added yourself and
logout and log back in before testing.

Thanks,
Joe

Thanks, Joe.  I'll try this later when I'm at the machine's location.
 Doesn't sound like a smart thing to try remotely. ;-)

Re: Printer Daemon (Update)

[Tim Darby]

Success, thanks!  Just a few comments:

- When I look at the commit history, it appears that the part you changed
has been like that all the way back to the beginning of the project?
- When I rebuilt kernel and world, I went ahead threw in all the recent
MFC'ed things.  Now, when I print to lpt0, I'm seeing these messages, which
I assume are harmless:

Nov 25 08:58:34 ocotillo kernel: sched_ithd: stray interrupt 7 on cpu 0
Nov 25 08:58:34 ocotillo kernel: sched_ithd: stray interrupt 7 on cpu 0
Nov 25 08:58:34 ocotillo kernel: sched_ithd: 10 stray interrupts 7 on cpu 0
- there will be no further reports

- Just to satisfy my own curiosity about the code:  how does lpr.c
eventually get to unp_connect()?  I followed it as far as connect() in
startdaemon.c and then lost the trail.

Thanks,
Tim

I haven't really followed this thread, but to answer this question: 
connect -> sys_connect -> ... -> some routine eventually sends an lwkt 
message to the protocol handler for connect, which for this case will be 
unp_connect()

I don't know if this issue has been here all along as I almost always
add myself to the wheel group.  Do you know that this worked in the
past?  If so, do you know what time frame.

I think you can ignore these if printing is working for you.

Thanks,
Joe

Re: Printer Daemon (Update)

[Tim Darby]

I think I've always added myself to wheel too and just recently stopped
doing that, so I can't say if printing as an unprivileged user ever worked
in the past.  Thanks again for the fix.
