Howto: Java Plugin for Firefox 3.0.1?
by James B. Byrne 19 Jul '08

19 Jul '08

Can anyone here give me the magic decoder ring recipe for getting jre "plugged" into Firefox 3.0.1? The plugins directory is gone and the Firefox FAQ regarding this issue cryptically mentions that plugin support has been dropped. It then points one to a early adopter SUN jre1.6-10 page that has innumerable dependencies which my version of CentOS-5.2 does not meet. Firefox 3.0.0 had a plugins directory and it did support the logical link plugin: ls -s libjavaplugin_oji.so /usr/java/default/plugin/i386/ns7/libjavaplugin_oji.so I have no clue how to get java to work in FF3.0.1 at the moment. Any help would be appreciated. -- *** E-Mail is NOT a SECURE channel *** James B.

Re: [CentOS] Getting printer to work under 5.2

Yes on both counts. That's where I was dealing with the parts about the one-dependancy-mentionned-at-a-time part. No luck, hence the reason for uninstalling it and reverting to the yum repository. > From: Anne Wilson <cannewilson(a)googlemail.com> > Subject: Re: [CentOS] Getting printer to work under 5.2 > To: CentOS mailing list <centos(a)centos.org> > Message-ID: <200807171028.02611.cannewilson(a)googlemail.com> > Content-Type: text/plain; charset="utf-8" > > On Thursday 17 July 2008 04:04, Donald Buchan wrote: > > I have a standard hplip install on my 5.2 box installed from the repos > > (it originally was installed from the 5.1 disks and followed any upgrade > > that may have occured in the transition to 5.2).

semi OT: logwatch results
by Robert - elists 19 Jul '08

19 Jul '08

Semi Off Topic My searching hasn't found what I consider superior info, and we are wondering from others experience on this list... In the logwatch results we all see the info below on almost a daily basis I have taken the liberty of combining logwatch results from centos 4 and 5 machines for extra info and future searchability ----- Centos 4 ----- --------------------- httpd Begin ------------------------ GET http://scifi.pages.at/myproxies/azenv.php HTTP/1.1 with response code(s) 404 1 responses GET http://thecric.free.fr/AZenv/azenv.php HTTP/1.1 with response code(s) 404 1 responses ----- Centos 5 ----- --------------------- httpd Begin ------------------------ Requests with error response codes http://scifi.pages.at/myproxies/azenv.php: 2 Time(s) http://thecric.free.fr/AZenv/azenv.php: 2 Time(s) GET http://scifi.pages.at/myproxies/azenv.php HTTP/1.1 with response code(s) 404 3 responses GET http://thecric.free.fr/AZenv/azenv.php: 2 Time(s) HTTP/1.1 with response code(s) 404 3 responses Is it like people are setting up servers to do advertising in our logs while looking for some vulnerabilities? Thanks in advance for your insight... :-) - rh

How to examine crash dump of Centos Kernel
by Nataraj 19 Jul '08

19 Jul '08

Hi, I have been able to successfully use crash to examine a crash dump of kernel-PAE-2.6.18-92.1.6.el5 using the following command: crash /boot/System.map-2.6.18-92.1.6.el5PAE /usr/lib/debug/lib/modules/2.6.18-92.1.6.el5PAE/vmlinux ./vmcore I then installed the package kernel-debug-2.6.18-92.1.6.el5 and rebooted with that (there is no PAE debugging kernels in the repository). I reproduced my crash and collected a crash dump, however when I try to examine the dump I get the following error: crash /boot/System.map-2.6.18-92.1.6.el5debug /usr/lib/debug/lib/modules/2.6.18-92.1.6.el5/vmlinux ./vmcore crash: v2 module syment space malloc (2005518689 symbols): Cannot allocate memory I have used ulimit in the shell to set all of the limits to unlimited and I still continue to have this problems. Any ideas? Is it possible that I would need a 64 bit OS in order to examine a 4gb crash dump with symbols and debugging information? I have the following kernel-debuginfo packages installed: kernel-debuginfo-common-2.6.18-92.1.6.el5 kernel-PAE-debuginfo-2.6.18-92.1.6.el5 kernel-debuginfo-2.6.18-92.1.6.el5 I am running CentOS 5.2 on a dual Xeon Server with 4gb of memory. Thanks, Nataraj

2 questions on diskless client setup.
by centos＠mjt1.com 18 Jul '08

18 Jul '08

Using Centos 5.2 upgraded from 5.0 using yum on a couple of old Dells in a lab environment. I don't think hardware is part of the problem, just need configuration help. 1: I can boot the diskless client and it come up, but when I do a "mount" command on the client, the output is indistinguishable from the output of the mount command on the server. Currently the fstab in .../root and .../snapshot/<diskless client name> have no entries in them. I set this up using the "how-to" from the Centos web site, I might be missing something. I was wondering if someone could point me to information on how NFS mounts and fstab files work as well as how the "root" and "snapshot" directories work. I'm guessing that snapshot is where you set up the unique personality of each client, while "root" is global to all clients, but I would like info on how it all works together. I could continue to guess and try to figure it out on my own, but my experience has shown that I might get a working solution that is NOT the best. 2: I am running NFS4. I also set up all the diskless clients in an /export directory that is shared with several other exported directories (its a lab, so the devices do double or triple duty). My export file has /exports with the "fsid=0" flag. So, when I mount, I don't have to have "/exports" in the directory string. All is fine until the initial mount done by netboot(?), it issues the first mount command with "/export/diskless/i386/centos5.2/" as the directory string and fails. To work around this, I put a link in that links /export to /export/export and exported /export/export. UGLY I know, but it was the work around I discovered. Anyone know a better way of dealing with this?

configuration request
by Sam Drinkard 18 Jul '08

18 Jul '08

I've apparently gotten myself into somewhat of a bind. I've been trying to exclude various packages from the different repos, and while I *think* I've gotten a working configuration again, it it still pulling stuff in that I have excluded I think in the right repos, but things I have no use for whatsoever. Items like kernel-hugemem-devel, kernel-hugemem, and anything involving kernel development. I run a stock kernel and am not doing any building of any kind at this point. The machine is an i-686 machine, and a single processor. I'd be very much appreciative if someone could send me,, or post a proper repo config that points to the various exclude lines to get rid of some of the unnecessary files. It's taken me about 2 hours of modifying stuff to finally get a yum repo config to make it all the way thru. Also, can I perhaps just yum erase some of the software I never use, like seamonkey and probably others so it does not even have to look for updates for those packages? Would that be the proper way to eliminate the fluff? Any type of help here would be great! Thanking you in advance, Sam

We've been seeing the same type of entries in our Web server logs for at least a couple months now and not just a few entires. It isn't just `azenv.php', but references to other PHP files that do not exist on our systems. They've hit some of our servers so hard I figured it must be some kind of attempt to break in or a weird kind of DOS attack. -- Brent L. Bates (UNIX Sys. Admin.)
