lp can't open file

George Liu_2 — Thu, 10 Apr 2003 22:00:07 GMT

very frustrated by this problem.

#uname -a
HPUX 10.20

#cd /etc
#lp hosts
#can't open hosts

#lp /etc/hosts
print OK

#which lp
/usr/bin/lp

#more hosts
display hosts OK

Any idea is appreciated.

And the permissions on this file are?
And the user issuing these commands has what permissions?

This is a good one George. I have to guess it is the remote login environment causing this.
Can you more and vi any other file when logging remotely?

After issue of the lp command, is the print in the print queue?

We'll get this!

u may try:
cd /etc
lp ./hosts

Re: lp can't open file

George Liu_2 — Fri, 11 Apr 2003 15:44:20 GMT

lp ./hosts

doesn't work either. Same error message

cannot open file hosts

However, I still can more or cat or vi hosts

by

more hosts

The permission of hosts is
rw-r--r--

Thanks.

I am curious is someone hadn't put a "wrapper" on /usr/bin/lp. Could you publish an ll of /usr/bin/lp.
Here it is on one of my 10.20 boxes:

root> uname -a
HP-UX chop B.10.20 A 9000/715 2001081504 two-user license
chop:[ /etc ]
root> ll /usr/bin/lp
-r-sr-xr-x 1 root bin 45056 Nov 2 2001 /usr/bin/lp
chop:[ /etc ]

root> what /usr/bin/lp
/usr/bin/lp:
$Revision: 78.29.1.96 $
PATCH_10_20: hpux_rel.o lp.o 01/11/02

Forgot to "what" it for you.

Hi,

What is your permissions on /etc? What does 'ls -ld /etc' return?

Also, what does 'echo $CDPATH' return?

# echo $CDPATH
CDPATH: Undefined variable.

Thanks.

Hi,

I'm stumped. Has this problem just happened recently? If so, what has changed on the box lately? Patches? Any config files modified such as root's .profile, etc.?

JP

Re: lp can't open file

George Liu_2 — Fri, 11 Apr 2003 17:19:51 GMT

Frankly I don't know. Only few people rarely use this box, and fewer chances to use printer. Thanks.

BTW, Does lp use $CDPATH to search the file or some other methods?

Re: lp can't open file

John Poff — Fri, 11 Apr 2003 17:29:32 GMT

Hi,

The CDPATH is used for searching paths for the cd command to change directories. It was a wild guess.

Do you have a default destination set for your lp printing? Also, does lp have the same problem with other files in /etc or does it print them? For example, can you do:

cd /etc
lp services

or does that complain also?

JP

Re: lp can't open file

George Liu_2 — Fri, 11 Apr 2003 17:35:35 GMT

Yes. lp has problem for all files if using syntax

lp filename
or
lp ./filename

but it works for syntax like

lp /directory/filename

Thanks.

Re: lp can't open file

John Poff — Fri, 11 Apr 2003 17:45:09 GMT

Ok. Does lp work for printing files from other filesystems? For example, can you go to /var/adm and find some small file to print there? I'm curious to see if it is just a problem in the /etc filesystem or if it happens in other filesystems as well.

Also, do you have a default printer destination set for your lp spooler, or is it undefined?

Bill Douglass — Fri, 11 Apr 2003 18:33:49 GMT

I don't have a 10.20 system to test, but tracing lp on HP-UX 11.0 indicates that the process does a stat and access syscall on the file in question as user lp, group lp.

It also (as lp) tried to link the file to /var/spool/lp/request//. If that fails (cannot link across file systems), then it copies the file instead.

If you have it installed, it would be helpful to see a trace output from running "lp host". If you don't have it, you can d/l it from

George Liu_2 — Fri, 11 Apr 2003 18:50:18 GMT

Thank you, all.

All accounts except lp can't open a directly file in all directories.

If I
su - lp
then
lp filename
works just fine.

Maybe need to patch now.

I'm installing a tracing tool to try. Thanks.
