rpm question
by Jerry Geis 14 Aug '09

14 Aug '09

When I install some RPMS like openoffice 3 on centos x85_64 is there some command that will leave all the actual files alone (leave them installed) but just remove the RPM name from the RPM database so centos now things the packages are not installed? Reason is I was wanting to do this so a next yum update does not get all confused... and the yum update happens just like I never installed openoffice 3. is there a way to do that ? Jerry

(solved) HP C4580 printer x86_64
by Shawn Brown 14 Aug '09

14 Aug '09

Hi, I managed to get my C4580 (4500 series) connected to my router to work with 64 bit 5.3. That printer needs at least hplip 2.8.10 which I found at http://rpm.pbone.net/index.php3/stat/4/idpl/12086038/com/hplip-2.8.10-0.1.e… It was just a matter of following the manual install instructions for hplip here http://hplipopensource.com/hplip-web/install/manual/distros/redhatenterpris… and then getting the necessary dependencies. In the end it worked with (this is for the last line of step 3 in HP's instuctions) rpm -Uvh ./hplip-2.8.10-0.1.el5.test.x86_64.rpm ./python-imaging-1.1.6-2.el5.rf.x86_64.rpm ./hpijs-2.8.10-0.1.el5.test.x86_64.rpm ./net-snmp-5.3.2.2-5.el5_3.1.x86_64.rpm ./net-snmp-libs-5.3.2.2-5.el5_3.1.x86_64.rpm ./lm_sensors-2.10.7-4.el5.x86_64.rpm I'm happy with HP's Linux support!

The immediacy of E-Mail simply does not promote the reflective approach required to create effective written communication. However, what can be compensated for by body language when stated in person may project a brusque and contemptuous tone in writing so that failing to take the necessary time extracts its cost in needless upset and conflict. There are a few other things that people should really consider before they dash off their offhand remarks. Firstly, it is unwise to shout at ones watchman, for the next time they see something suspicious then they may remember the first occasion and hold their tongue. If somebody senses something is wrong then they should be civilly treated when they bring it to our attention. Even if their concern is the result of their misapprehension this is a sign that perhaps the information provided needs revisiting and revision. I doubt that anyone could reasonably hold up the documentation of most software as exemplars of clarity and comprehensiveness. Secondly, not all of us, I speculate that not even most of us, work in large organisations. In fact, I would venture to guess that most people using CentOS are found in small shops or even sole practitioner sites. So, railing about how things should be run given infinite resources and time simply of flies in the face of the realities surrounding OSS utilisation and is completely useless. Thirdly, the Net has a surfeit of nannies. If you are not yourself going to deal with the issue raised then keep silent. If the 'signal to noise' ratio is bothering you then at least withhold your own contribution to the noise. -- *** E-Mail is NOT a SECURE channel *** James B.

OT: Firefox SSL error on Linux, Firefox OK on Windows - same web site
by Lanny Marcus 13 Aug '09

13 Aug '09

Using CentOS 5.3 (32 bit) on my Desktop with Mozilla Firefox 3.0.12. With one web site (LinkShare) I am getting an SSL error, after clicking to get a more advanced report I do not get that error, using Mozilla Firefox 3.0.13 on M$ Windows and I get the report OK on Windows. It appears, when using Firefox on Linux, that it is not ending up on the LinkShare web site and Firefox is giving me the below error. I use OpenDNS.com for DNS service. Question: How can I verify that there is no corruption in my Firefox installation on Linux and that I have the latest SSL CAs for it? TIA! Lanny Secure Connection Failed analytics.linksynergy.com uses an invalid security certificate. The certificate is only valid for *.opendns.com (Error code: ssl_error_bad_cert_domain) * This could be a problem with the server's configuration, or it could be someone trying to impersonate the server. * If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

Dangerous Software Raid instructions on Wiki
by Chan Chung Hang Christopher 13 Aug '09

13 Aug '09

http://wiki.centos.org/HowTos/SoftwareRAIDonCentOS5 has: dd if=/dev/zero of=/dev/sda bs=512 count=64 dd if=/dev/zero of=/dev/sdb bs=512 count=64 Will the joker who put in this particular gem without any warnings or a clear explanation for those who need a clueby4 with regards to file systems please either remove the instructions or add a very clear warning that damage to file systems that is not recoverable will result if run on the wrong disk(s). My successor at my previous job has gleefully followed those instructions (he seriously needs a clueby4 which is why he bothers to actually read HowTos) and on a production box (who wants pop-corn and soda? Sorry, the er support conversation will not be on irc) and I think this seriously highlights the need for HowTo writers to seriously consider their audience as dumb monkeys that just follow whatever you tell them to do without thinking if you do not list out things they first have to think about or questions they first need to answer.

Then you would be wrong. Once his mind was made up then Wilson became quite closed to further suggestion on a subject. Up to that point he sought as wide and varied a range of opinion as he could obtain. Your pride in what you know is blinding you to the value of knowledge of others in areas where you know little and presume much. I have had much experience with volunteer organisations. I now stay well clear of any involvement with them. This recent string of interrogations by concerned people, whether ignorant or not, and the aggrieved tone of the responses of some of the inner circle demonstrate the type of emotional blackmail which I frequently encounter and find so distressful in these bodies. I have no doubt that everyone involved with CentOS is pursuing some goal that they believe serves the greater good. However, difficulties ofttimes arise when one encounters another who either does not share ones belief or, as is more often the case, understands the nature of the shared goal, or the means by which it is attained, in a fashion fundamentally at odds with ones own. These uncomfortable collisions with political reality often occur at junctures such as CentOS recently experienced. Most of the people here were no doubt quite content to allow the sages of the project whatever leeway that the sages desired. In return we got a free (as in beer) copy of a very reputable Linux distribution. Had the recent inner conflict not become public then this happy arrangement might have persisted indefinitely. I still consider this arrangement a very good bargain having neither the talent nor the desire to become a sage myself. However, when the mortal nature of the sages is revealed together with the possibility of a project collapse as very real consideration, regardless how unlikely, then those dependent upon the stability of the project become fearful. Fearful people seek reassurance that their fears are baseless. A bald statement by the sages that the fear is baseless is in itself insufficient. Doubtless the fearful have told themselves that many times already. Having inoculated doubt it is now incumbent upon those who sowed it to address specific concerns raised by those who fear. Telling people who voice concerns to get lost and find another distribution, even if their concerns are presented in the form of ill-considered suggestions, smacks of arrogance to me, however it appears to others. Further, it does absolutely nothing to address the fears that prompted the suggestion. The baleful effects of these kind of replies upon those who read but choose not to participate may only be imagined, but be assured they are neither positive nor insignificant. The fact that one is a volunteer leader does not lessen the requirement that to receive the trust and support of others one must meet satisfactorily the expectations of those who follow. I am not clamoring for any immediate changes. I do not propose a program that I wish anyone else to follow. I do appreciate very much the efforts of all who contribute to the success of the CentOS projects. I further acknowledge that those who presently form the core support team are probably best equipped to evaluate the bona fides of prospective core members. Nonetheless, it is very evident from the heated exchanges on this mailing list that there exists a substantial divergence on which path to take from here. It seems to me insupportable that the past practices of a small coterie of initiates deciding on everything without community input will suffice for the future. If that does become the choice taken then I foresee the community splitting in the future in consequence. Finally, please drop the word "meritocracy" in future communications. It implies a natural worthiness of those to whom it is applied which is simply not appropriate to these discussions. The proper word in this circumstance is "oligarchy." -- *** E-Mail is NOT a SECURE channel *** James B.
