 I set the printer type as raw and then restarted cups just to make sure

Avoid cups for a quick test:

2 ways: 

1) get the lprng rpm and extract lpr and lpq to a
directory, both should be usable even with little to no
configuration aside the normal host printing setup. The 
nice effect: things like lprng -...@host just work, without
adding queues, discovery and other annoyances.

2) just ftp the file to the printer (maybe newer jetdirect
cards also support things like ipp / http as well?).

The 2nd method at least reduces the components being
tested to the raw network connection between two boxes.

And of course, effects due to funny things being printed
(testing with multiple printers and having one set of tests
print a single file run thru gs to produce pcl-3 or higher may 
be a good way to detect funny postscript like strange font
embedding (e.g. from the application/library/... on a badly
configured client), or full color for a blackwhite laser, etc).

[CentOS] Centos 5.4 'prerelease-access' - is there such a thing?

2009-09-12 Thread Peter l Jakobi
Hi,

excluding  the  Frankengrade  from CENTOS5.3 to upstream  RHEL5.4,  is
there are procedure / repository access / nightly builds / ... to what
will be CENTOS 5.4?

URLs? Howtos? Discussion threads or notes?

I  checked  help, wiki and forums and google, but came up empty. 

Of  course, this kind of use is depending on the way the new  upstream
RHEL  sources are processed, so maybe there won't be a complete set of
packages  at all until maybe one or two weeks before the release.  But
again I got no lucky search hits for this kind of internals either.

I'll  gladly collect and summarize for a (hopefully easier  locatable)
wiki-page to be :).

cu,
Peter

Re: [CentOS] Commands failing silently?

 You can also try running ``strace /bin/ls'' to see what is going on.
 Funnily enough, running strace will work just fine. Though, as I said, just
 about any command will fail -- 'ls' was just for testing purposes.

That's  funny. Or due to the output of strace changing timing  stress.

Try  redirecting the strace output to a separate (local filesystem  or
ramdisk) file, possibly restricted to file operations. Also: check top
- you don't have swap or ram problems?
