hostname changes
by Carlos Santana 16 Jun '09

Howdy, How do I change the hostname? In particular, what is the difference between /etc/hosts and /etc/sysconfig/network files? Where should I make the changes? Thanks, CS.

Trouble (?) reformatting flash drive to include former U3 partition
by MHR 16 Jun '09

16 Jun '09

Semi-OT? I just got a new SanDisk 8GB flash drive, and, as usual, it came with the U3 software (for Windoze) on a "CD" partition and considerably less than 8GB on the disk partition. I put it into my WinXP portable and told U3 to delete itself, but I still can't get at the old U3 part of the drive. I've tried WinXP's format command, disk management and CentOS's fdisk, and nothing will give me more than 7,872,512 bytes per cylinder, times 1019 cylinders yields 8,022,089,728 bytes. Is that right, or should there be more? fdisk also reports that the drive has 8029 "MB", or 8029470208 bytes, which is 7,380,480 bytes difference (until it gets allocated into the 8,022,089,728 bytes of the partition) - I'm thinking this is a standard formatting loss. My 4GB flash drive has 4,096,189,440 bytes on it, and twice that would be 8,192,378,880, which is a difference of 170,289,152 bytes, or about 162+MB. The former "CD" partition (which is invisible, so far) only had 8,645,202 bytes used on it, which leaves a huge amount of room to spare of inaccessible empty space. What am I missing? Or is that just the way it is? (The package only says "Some capacity is not available for data storage." That doesn't really tell me enough.) Thanks. mhr

OT - Tomcat CLASSPATH issue
by Tom Brown 16 Jun '09

16 Jun '09

if this is ignored then fair enough as its not really the place for it but if anyone has seen this it would be good to know tomcat is 6.0.18 CLASSPATH is set in /etc/sysconfig/<appname> and this IS getting used as _some_ configuration items are being picked up from /etc/<appname> but the issue is when default setting from within the webapp are not being overwritten by settings in /etc/<appname> ie if they are in /etc/<appname> and /var/lib/<appname>/webapps/ROOT/WEB-INF/classes/foo then the webapps location wins. If i echo the CLASSPATH during app start then /etc/<appname> comes first so i dont see why the values in here are not taking precedence any thoughts?

I was originally asking what howtos to look at, since I couldn't find centos howtos. then I found wiki.centos.org. Is it really of no interest to anyone else which rev of RH corresponds to which rev of fedora and centos? > If I were you I'd look more into dkms and the dkms-nvidia-packages. Those > are more current, than the driver package in nvidia-x11*. Useful suggestion. The wiki page I was looking at made no helpful distinction between them, so I picked the one that sounded simpler. > Or if all else fails, why not get the proprietary Nvidia drivers? Well, all else did not fail. And they want me to run a script that does I don't know what, outside the record-keeping that goes with yum/rpm. Also, nvidia's web page made it sound like I was in for an editing session on xorg.conf, which is beyond me. Maybe I misunderstood. Dave

OT: need advice on drive controller
by Robert Arkiletian 16 Jun '09

16 Jun '09

I am thinking of getting an Areca ARC-1222 connected to 6 sata drives in raid 10. http://www.areca.com.tw/products/pcietosas01.htm I have read good things about the ARC-1220 (iop333) sata only. The ARC-1222 (iop348) is the newer generation (sata or sas). Does anyone have advice/experience on this drive controller? -- Robert Arkiletian

nvidia dual monitor setup centos howto
by Dave 16 Jun '09

16 Jun '09

I had some trouble setting up dual monitors on centos with an nvidia card. I managed to track stuff down, so I thought I'd make it public on the list. I have an nvidia quadro nvs 290 in a Dell, recently installed centos5. Same stuff should apply for other nvidia cards. I needed nvidia-x11-drv.x86_64. It is available from rpmforge. Installing rpmforge is described on this page(http://wiki.centos.org/AdditionalResources/Repositories/RPMForge). If you just open the display panel and choose dual monitor settings and restart X, X can't get started and gives error messages. When I restore the old /etc/X112/xorg.conf, it comes back to life, without dual monitors of course. Here are the actual commands I entered as root: yum install yum-priorities echo 'priority=1' >> /etc/yum.repos.d/CentOS-Base.repo echo 'priority=1' >> /etc/yum.repos.d/CentOS-Media.repo echo 'priority=2' >> /etc/yum.repos.d/epel.repo echo 'priority=2' >> /etc/yum.repos.d/epel-testing.repo echo 'priority=3' >> /etc/yum.repos.d/adobe-linux-i386.repo echo 'priority=3' >> /etc/yum.repos.d/rpmfusion-free-updates.repo echo 'priority=3' >> /etc/yum.repos.d/rpmfusion-free-updates-testing.repo echo 'priority=3' >> /etc/yum.repos.d/rpmfusion-nonfree-updates-testing.repo echo 'priority=3' >> /etc/yum.repos.d/rpmfusion-nonfree-updates.repo wget http://apt.sw.be/redhat/el5/en/x86_64/RPMS.dag/rpmforge-release-0.3.6-1.el5… rpm --import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt rpm -K rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm yum --localinstall rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm yum localinstall rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm yum check-update yum search nvidia yum install nvidia-x11-drv.x86_64 I originally googled around for a howto, it took me much more effort than it should to find http://wiki.centos.org. Wonder if there is a way to get google to give better results? Found someone with similar problems, someone suggested installing the right thing but neglected to point out where it comes from. So I was getting this: sudo yum search *nvidia* Loaded plugins: fastestmirror, security Loading mirror speeds from cached hostfile * rpmfusion-nonfree-updates-testing: mirrors.cat.pdx.edu * epel: mirror.its.uidaho.edu * rpmfusion-free-updates-testing: mirrors.cat.pdx.edu * rpmfusion-nonfree-updates: mirrors.cat.pdx.edu * extras: mirrors.cat.pdx.edu * rpmfusion-free-updates: mirrors.cat.pdx.edu * updates: repos.lax-noc.com * base: mirrors.xmission.com * addons: repos.lax-noc.com Warning: No matches found for: *nvidia* No Matches found Which versions of RH or FC correspond reasonably well to my version of centos? uname -a Linux 2.6.18-128.1.10.el5 #1 SMP Thu May 7 10:35:59 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux thanks, Dave
