YUM: public key not available for perl-XML-Parser
by Todd Cary 15 Aug '05

15 Aug '05

I am not sure how to fix this problem: When I do a yum command, almost all of the packages are installed, but I get *public key not available for perl-XML-Parser *How do I get that particular key? Todd -- Ariste Software 200 D Street Ext Petaluma, CA 94952 (707) 773-4523

Using YUM
by duffmckagan 15 Aug '05

15 Aug '05

I haven't configured YUM . How do I do it? Sorry if this is a really stupid question, but I have no idea about it. Moreover, I would also like to use APT afterwards. I really want to try both of these. I have used apt-get before many a times, but never used YUM. Can anybody post the procedure to get this working? Which repositories to be added, how it is to be configured? And yes, how do i use the apt-get on Cent OS too. Note that I will be using only one at a time. And I will keep the other thing for future reference. Thank you. -- "No-one dies a virgin. Life screws everyone."

Best way to add/update an installation
by Todd Cary 15 Aug '05

15 Aug '05

In an effort to prevent getting many minutes into an installation only to have a CD read fail (I did verify the CD's first), I did a minimal install. Can I use the minimal install to add the necessay packages for a HTTP server and graphical interface? Todd -- Ariste Software 200 D Street Ext Petaluma, CA 94952 (707) 773-4523

Kickstart, package always selected
by Fong Vang 15 Aug '05

15 Aug '05

I'm trying to kickstart a Centos 4.1 system with the minimum set of packages. I have no use for ypbind so I'm trying to prevent from being installed, but kickstart/anaconda always insist on its installation (complaining that the package is missing). This is the %packages section of my ks file so far: %packages #-@ dialup kernel grub e2fsprogs lvm2 -slocate -bluez-utils -bluez-bluefw -bluez-hcidump-1.11-1.i386.rpm -isdn4k-utils -pcmcia-cs -ppp -wvdial -ypbind as you can see, ypbind is deselected in the ks file. Is ypbind a mandatory package? In the RPMS directory, I tried to determine what package may be requiring ypbind, but I could find any. This is what I used to determine what package may be requiring it: cd CentOS/RPMS for i in *.rpm; do echo ---------------- $i; rpm -qp --requires $i 2>/dev/null | grep ypbind && echo ******** $i *******;done

ethernet interfaces swapped around
by sudo Yang 15 Aug '05

15 Aug '05

One of my systems have two onboard NICs which uses the e100 and e1000 drivers (yes, the interfaces are not the same). This system kickstart fine with CentOS 3.x. I recently tried to rekick it with CentOS 4.x but was unsuccessful in doing so. When kicking CentOS 4.1, the interfaces are swapped around, i.e. eth0 becomes eth1 and eth1 becomes eth0 (as described at http://marc.theaimsgroup.com/?l=linux-kernel&m=104888957013124&w=2) Is there a way to fix the interface during kickstart? Unfortunately, because we have so many different types of systems, simply swapping the cables is not a good idea because it complicates management.

DVD-RAM writer software for CentOS4
by James B. Byrne 15 Aug '05

15 Aug '05

Firstly, let me thank all of the individuals who assisted me in various matters regarding find, tar and ssh last week. Your contributions were truly invaluable and I learned a great deal thereby. The reason for that brief flurry of activity was an administrative and technical move to store-to-disc from store-to-tape for our server backups. We presently use a mix of store to disc on various servers and store to tape depending upon the point of origin; store-to-disc for MS- Windows and Linux, store to tape for our HP3000 mid-range. These disparate backup strategies are now being marshalled onto a pair of Linux servers, one on-site and one at a remote location. At this juncture we are contemplating methods of creating off-line archives as well. In this regard I seek your advice regarding the suitability of employing an LG model GSA-4163B multi-format DVD drive as a backup device using DVD-RAM 120mm media. Specifically I wish to know what software is available under Centos4 to record to this drive and which of those are preferred for this sort of application and how suitable each is for untended backups. I understand that DVD ram has a ~4GB limit and that filesets in excess of that naturally require a disc change. We also are looking at tape systems. The idea is that we will end up with a four stage backup process. 1. Daily automated backups of each server over the network to a local high capacity linux server devoted to hosting the backup volumes. 2. Daily automated moving of certain critical, volatile backup sets from those on-line local stores via ssh to an off-site server performing the same function. 3. Daily semi- automated (somebody has to change the disc) stores of less critical and only somewhat volatile data onto DVD kept on-site in a fireproof vault. 4. Semi-automated archiving of the rest onto tape on a weekly basis and moving these off-site (the backup job is automatically scheduled but the media has to be manually handled). We currently use an internal DDS3 tape unit for store-to-tape and are considering changing to an external DLT drive. I would welcome comments regarding a suitable choice of external DLT tape drives for this application. We have used an external SCSI DLT device in the past but this device needs to be replaced and are open to alternatives. The total volume of data handled by all these these processes is not prohibitively large. We are speaking of tens of giga-bytes (~40GB) over all.

How can I make these command prompt settings into universal settings?
by Dave Gutteridge 15 Aug '05

15 Aug '05

I've got it so that I can enable Japanese input into an application by typing the following at a command prompt (with FireFox, for example): [dave@localhost ~]$ kinput2 -canna & [1] 10631 [dave@localhost ~]$ XMODIFIERS='@im=kinput2' LC_CTYPE=ja_JP.utf8 firefox However, I would rather not have to type in all that craziness each time I want to start an application. Further, instead of having to configure each application individually, it would be better to have this setting just on all the time for every application, both existing and new. I was under the impression this was possible. Following advice gained elswhere, I thought I could put the following into /etc/X11/Xresources: ! Japanese Input #!/bin/sh XMODIFIERS='@im=kinput2' LC_CTYPE=ja_JP.utf8 kinput2 -canna & But doing so results in Japanese input not being available for any application. I'm using KDE, and I learned that I should be able to put any shell script in the ~/.kde/Autostart/ directory and have it launch on start. So I put a file there called j-input.sh, changed it's permissions with chmod 755, and put the same commands that I had in Xresources. But still no result. Long story short: How do I get these command line settings to be permanently on: XMODIFIERS='@im=kinput2' LC_CTYPE=ja_JP.utf8 kinput2 -canna & Dave

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
