I've lost control of Gnome
by Dave Gutteridge 15 Aug '05

15 Aug '05

I tried out KDE for a while, but eventually found that it was not to my liking. I've switched back to Gnome, but it seems to me that options I used to have in the panel aren't available anymore. I'm not totally sure, but isn't there supposed to be some sort of Gnome (Nautilus?) control center? A place where I can adjust the themes, screen savers, and that sort of thing? I was sure it was there, and now I can't find it, and I'm lost about exactly which problem I should be fixing. Should there be a theme manager? If so where? I came across a theme switcher application, installed the RPM, and I can't find it in the applications menu either. Is Gnome upset with me for having been with KDE behind it's back? Dave

Unfortunately, telling them to get over it ain't anywhere near an option here. If it was my office ... well, I've worked without flash for aeons because I don't like it and I just don't visit sites that use it exclusively. But this client of mine is a sales company and needs to visit these sites. I guess we'll work on it over the weekend to see if we can solve the dependency nightmare and get it up and running. It's too bad we don't have another 64-bit system hanging around to test on. Thanks! -Karl Katzke

expert guideance needed on arrays with CentOS 4 installed on dual processor compaq server
by Robert Hanson 14 Aug '05

14 Aug '05

greetings, as most know i have some older dual processor Compaq playtoys that i am deploying CentOS 4 on and doing some real world'ish simulation of failure and regular server environment testing. i have searched www on some things to no avail so off to the experts for some guideance please? case of: a dual Pentium 3 processor 1850R with a smart array 221 controller and quantity (4) 18 Gig SCSI hard drives in default specs RAID5 array created by the controller and Compaq Smartstart CD and i set the RAID rebuild to "highest priority"... Then, i do a custom install without Gnome or KDE of course. linux text lowres nousb nousbstorage skipddc install CentOS 4 using autopartition with a /boot 1024MB i.e. 1Gig / approx 50,000MB i.e. 50Gig everything installed perfect and i rpm --import /usr/share/doc/centos-release-4/RPM-GPG-KEY imported the key and do a full yum update to latest greatest CentOS 4 packages.... Now, i am trying to get some perspective and pointers so i can learn more how to better understand what i really have here. i know i have a lot to learn in regards to managing RAID5 on CentOS 4 Should I have autopartitioned? Is LVM the best way to manage RAID5 on CentOS? What other tools are there on a default CentOS 4 install to manage my array? What tools should i install with yum install to learn more and help me with this situation? If i shutdown the machine, and yank out any drive, and replace it with an identical drive and fire the unit back up, it asks me if i want to rebuild the data. Are these Compaq arrays "hot swap" like i think they are? How "long" does that usually take for it to rebuild by the controller? Hours? Days? Months? ;-> Remember, this is a (4) 18gig drive system. Should I allow the machine to be in production, online, up and running while it is rebuilding the 4th disk? Yes, I get the error from the kernel... non fatal error on ida/c0d0 ....while the machine appears to be rebuilding the 4th disk in the array... What other CentOS software tools should I be aware of to help me here? I really really appreciate your help and pointers and will go check out all of the documentation that you folks will point me to. Please remember, these boxes are not "in production" right now, so this is not an emergency, yet i am trying to simulate a production environment for obvious reaasons. Thank you in advance and kind regards, - rh -- Robert Hanson Abba Communications http://www.abbacomm.net

SD Card Reader not being recognized
by Dave Gutteridge 14 Aug '05

14 Aug '05

I have a USB card reader that handles various card media, like SD cards, Sony Memory Sticks, and two other formats that I can't even remember what they are. I pretty much exclusively use it for SD cards. With Fedora, when I plugged the card reader into the USB port, and then inserted an SD card, it would automatically come up on the desk top. However, this is not the case with CentOS. Nothing comes up. Naturally, I searched Google for information, hoping that maybe it was just a matter of downloading an RPM or something. But I did not come across any information that helped. Is there a setting that I need to activate in order for CentOS to recognize SD Cards and/or the USB card reader? Dave

quick question on RAID 1
by Ulrik S. Kofod 14 Aug '05

14 Aug '05

I have 3 disks that I want to setup in a raid 1, my questions is should I setup the 3rd disk as a spare-disk or should I mirror all 3 disks all the time? Will it perform *much* better to only mirror two and have the 3rd as a spare. Is it not safer to mirror all 3 drives all the time ?

CentOS-4.1 Beta for Alpha arch
by Pasi Pirhonen 14 Aug '05

14 Aug '05

Hi, As usually, i haven't heard of anything about it. I can see that someone has downloaded it, but nothing more. I am now poking you once again to _say_ something about it. My vacation is coming near and the summer isn't afecting to temperature of my machine room so much anymore, so i intend to nail this to official release at time of CentOS-4.2 update release cycle. But i can't fix things i don't even know being broken. I do have things like compat-glibc now, but if there isn't going to be any feedback, i'll just package it with the fixes i do find necessary. Don't get this ranting wrong. I am just poking for info to make things better. -- Pasi Pirhonen - upi(a)iki.fi - http://iki.fi/upi/

SSH hostname login
by Kai 13 Aug '05

13 Aug '05

I run CentOS 4.1 on a remote server and did a minimal installation. My problem is that I can not login using the HOSTNAME, must use the IP. 1. edited the - /etc/sysconfig/network 2. changed - HOSTNAME=a266 3. restarted the network Looks ok, hostname appears when logged on via IP, but can't use the HOSTNAME to log on from client. --- [kai@localhost ~]$ ssh a266 ssh: a266: Name or service not known --- [kai@localhost ~]$ ssh 192.168.0.101 kai(a)192.168.0.101's password: Last login: Sat Aug 13 17:13:09 2005 from 192.168.0.102 [kai@a266 ~]$ --- I can't figure out where I missed out. kai

Where to go for KDE questions.
by Dave Gutteridge 13 Aug '05

13 Aug '05

I've been trying, unsuccessfully, to log in on the KDE forums on the KDE web site. Unfortunately, despite having registered, my account is not "activated", and I can't post threads. I am also not able to email the forum administrator, as one ironically has to be an activated member to do so. I've also noticed that trying to search their forums results in a MySQL error. So does anyone have a recommendation for a different group or community on line where KDE questions would be welcome? Dave
