pdflatex: fuzzy fonts in Evince, but not on paper output
by Niki Kovacs 09 Mar '08

09 Mar '08

Hi, I've been using LaTeX for a few years on Mac OS X, and I'd like to use it on CentOS now. I installed a complete environment using 'yum groupinstall "Authoring and Publishing"' and then installing tetex-xdvi, plus manually installing the 'memoir' class. I can run 'latex document.tex' ok: the resulting .dvi looks nice in xdvi. When running 'dvips -o document.dvi', I get a .ps file that I can view OK in Evince. But when I run 'pdflatex document.tex', the fonts in the resulting PDF are all ragged and fuzzy... though the print output is OK. I thought I'd rather post this question here, since the answer is probably distribution-specific. Any suggestions? Niki

Unable open raw socket in CentOS 5 - SE Linux and kernel capability interaction?
by S Roderick 09 Mar '08

09 Mar '08

I am wondering what is the interaction between SE Linux and the kernel "capabilities" in CentOS 5.1? I'm trying to open a raw socket and keep getting permission denied errors. I've tried using the lcap library to find that CAP_SETPCAP appears to be off in the kernel. For compliance reasons, I don't want to turn this on. I've also tried a hand-crafted SE Linux module policy. I have verified that the test program runs in the correct SE Linux domain and it generates no audit errors, but it still fails to open the port with permission denied. It appears that SE Linux is not preventing the socket being created (as evidenced by the lack of audit messages), so what am I missing? Do I still need to modify capabilities within the program, even if I'm using an SE Linux policy?

OpenOffice won't start up
by Therese Trudeau 09 Mar '08

09 Mar '08

Hi, I just ran an install of OpenOffice 2.31 on Centos 5.1 using these instructions - http://www.melvilletheatre.com/articles/openoffice-fedora/index.html Install seemed to go fine until I finished and then tried to start up K writer and none of the OO apps will start up from the menu. even though they are all showing up in start menu that 2.3 is installed. I'm using KDE mostly but have gnome installed also. Can anyone give me an idea as to how to correct? Thanks. _________________________________________________________________ Helping your favorite cause is as easy as instant messaging.

Problem getting Java Runtime Environment installed into OpenOffice
by Therese Trudeau 09 Mar '08

09 Mar '08

Hi, I'm having trouble getting my new install of OpenOffice 2.31 to find my newly installed Java Runtime Environment version jre1.6.0_04 (downloaded from Sun). I tried installing it via Tools>Options>Java (am using OpenOffice Calc to try to set it up). The options dialog box is finding the Free Software Foundation version 1.4.2, but it won't find the new JRE file. I tried clicking on Add and tried just about every directory I could think of and it's just not finding the JRE. I believe after doing a search, that the newly installed JRE is located in the /usr/java/jre1.6.0_04 directory, and went to that dir in the options dialog box in Calc, and tried every dir and sub dir in that main dir, and Calc is still is not seeing it. Can anyone please give me an idea as to how to find JRE and get it plugged in to OpenOffice? _________________________________________________________________ Climb to the top of the charts!

yum update best practices
by sprizes＠gmail.com 09 Mar '08

09 Mar '08

Hello, we run approximately 400 Centos servers at our company. We use cfengine for configuration management. I am looking for some documentation to do patching including kernel patches. I was thinking of just having each host run yum update via cfengine but not sure if there are any gotchas there? Should I just do yum update? or should i exclude the kernel and be more careful with those? how about glibc? I am wondering what other people out there do with such large installations. I'd very much appreciate any help or suggestions on this. Also, kinda related to the above is my question about the correct yum behavior when installing kernels. I've seen it sometimes make the new kernel the default in grub.conf but sometimes it doesnt? what is the designed behavior? best regards, SK

PE2950, RAID 0, failed disk
by Scott R. Ehrlich 09 Mar '08

09 Mar '08

I have a Dell PowerEdge 2950 with PERC 5/i, and 6 disks. Two disks have one logical volume via a hardware RAID 1 and consist of CentOS 5 64-bit; the remaining four comprise a logical volume via a hardware RAID 0, and is all user data. One drive on the RAID 0 went bad. I removed it while the system was on, tried a reboot, and the system hangs at RedHat Linux... Starting I tried to boot from a Fedora 8 CD, which sees the boot drives fine, but not the RAID 0 partitions. Visiting the PERC controller setup claims the RAID 0 volume is unavailable, or something similar, though it is defined, with one of the disks labelled as missing, since I removed it from the system. How do I get the partitions on the RAID 0 setup back? I have some of the data, but need the rest, if possible, and the remaining three disks appear physically healthy. I'm also going to work with Dell for some answers, and I've done a lot of googling. Thanks. Scott

There is ZERO redundancy in RAID0. Again, your data is gone. Replace the drive, partition it again, then use RAID1, 5, or 6 on your remaining drives to get some kind of redundancy. Then restore what you can from backups. -- Steven Haigh Email: netwiz(a)crc.id.au Web: http://www.crc.id.au Phone: (03) 9001 6090 - 0412 935 897

Firefox and xmms issue
by Frank Cox 08 Mar '08

08 Mar '08

I'm almost certain that I had this working before, but it seems to have quit. I used to be able to go to a web page, click on a .wav file and have it automatically load into xmms and play, and that was all there was to it. Today, I click on a wav file and it opens another empty Firefox window, then loads xmms and sits there until I hit the play button on xmms. Worse, if I close xmms and the empty Firefox window, then click on another wav file in the original Firefox window, it goes through the same process but then when I hit play I'm listening to the first wav file again. So... what happened? -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com
