Re: [CentOS] Slow printing to HP jetdirect from cups

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). -- cu Peter l Jakobi li...@kefk.oa.shuttle.de ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Centos 5.4 'prerelease-access' - is there such a thing?
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 -- cu Peter l Jakobi li...@kefk.oa.shuttle.de ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] Commands failing silently?

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? -- cu Peter l Jakobi [EMAIL PROTECTED] ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
