[hpoj-devel] experiences with SMP and RedHat 7

[PASCHAL,DAVID (HP-Roseville,ex1) <dav...@hp...>]

Hi.  I upgraded a spare PC to SMP and installed RedHat 7 and wanted to share
my experiences with it.

Once I got them set up, printing and scanning seemed to work, although they
seemed slower on SMP.  So far I haven't been able to reproduce Robert's SMP
printing problem, but I was only printing RedHat's ASCII and PostScript test
pages.  I did have one locked up print job, but I think that was because I
had a scan session open at the same time, which is a different bug.

However, I had a hard time getting printing set up initially.  RedHat 7
includes "LPRng" as opposed to "lpr".  For some reason, every time I
restarted lpd, it reset the ownership and permissions on the wrapfilter
script in the spool directory, making it non-executable.  The original
filter script was not affected, however.  Finally I had to just move
wrapfilter somewhere else, like /usr/local/bin, to make it work reliably.
Of course, if I set up multiple queues like this, then I would have to give
different names to each of the wrapfilter scripts.

Has anybody else run into this problem with RedHat 7, or is there a better
solution to prevent this problem (which appears to be a "security
precaution" that goes too far)?  I will update PRINT-HOWTO with this
information.
