How Undo Yum Upgrade

file command returns incorrect MIME type?
by Benjamin Smith 04 Mar '06

04 Mar '06

Here's the problem: [ben@kepler tmp]# file -i presentation.ppt presentation.ppt: application/msword I see lots of references to this problem, (EG: IMP, PHP bug, etc) all of which conclude, in various forms, "the problem is in your /usr/share/magic.mime, go away". But nowhere (that I've been able to find) is there actually a solution - and even the magic.mime file from the latest tar (downloaded from astron.com) didn't fix it, either. The magic file in the apache directory seems to come up with the answer of: no answer. When you access a ppt in apache, it comes back with a generic response rather than "application/powerpoint" Any ideas? -Ben -- "The best way to predict the future is to invent it." - XEROX PARC slogan, circa 1978

>Sweet. I downloaded the new v10 so I am looking forward to trying it out. I >noticed one of the requirements was sendmail. Does anyone know if postfix is >fine instead of sendmail? I prefer to run postfix rather than sendmail.. Scalix is based on the HP Openmail system. It's pretty much a complete replacement of the MTA. No postfix. I'm installing it for a small business. They use lookout for the client. This thing rocks. Shared calendar, public folders. All this stuff just works. I was able to integrate spamassassin and clamav with it also. The webmail access is really good too. They use tomcat5 for all the web stuff. All the administration is done via the java web interface. There is command line stuff I'm starting to scratch the surface on. I've installed community edition 9.4.2 and 10 on centos4. Good luck. Cheers, Tim

Problem with oracle&httpd...
by siva m 03 Mar '06

03 Mar '06

Hi, I have CentOS 4.2 installed on my PC and I've successfully installed Oracle 10g along with apache web server(httpd) and perl-DBD-Oracle. The problem is trying to connect to oracle to oracle from a CGI script. I defined all of the environment variables(ORACLE_HOME, LD_LIBRARY_PATH, PERL5LIB) in httpd.conf as well as apachectl scripts but I am getting the following error in the logs: ========================================= [Fri Mar 03 00:31:25 2006] [error] [client 192.168.251.6] Can't load '/usr/lib/perl5/site_perl/5.8.5/i386-linux-thread-multi/auto/DBD/Oracle/Oracle.so' for module DBD::Oracle: libclntsh.so.10.1: cannot open shared object file: No such file or directory at /usr/lib/perl5/5.8.5/i386-linux-thread-multi/DynaLoader.pm line 230. ============================================ Also I disabled SELlinux, defined all of the above mentioned env variables in /etc/profile but now use. One weird thing is that as a standalone perl script I can connect to oracle but not through CGI. Can any one please suggest what's going wrong or what am I missing? thanks in advance, Siv

Filesystems, GRUB, weirdness, oh my! [long]
by Drew Weaver 03 Mar '06

03 Mar '06

I am using SystemImager to auto-install about 500 different machines, some of them are CentOS; as you can Imagine I want to automate the installation of the bootloader; so I wrote a 2 scripts to accomplish this task. Why two? Because some of the machines are IDE, and some of them are SATA, and I need to be able to use the same disk image on both of the drive types. Here is the first bash script: if grep -q sda /proc/diskstats then TYPE="sda1" MOUNT1="/dev/sda1 /a/boot" MOUNT2="/dev/sda3 /a" else TYPE="hda1" MOUNT1="/dev/hda1 /a/boot" MOUNT2="/dev/hda3 /a" fi mount $MOUNT2 mount $MOUNT1 MOUNT3="proc /a/proc -t proc -o defaults" mount $MOUNT3 MKSYS="-p /a/sys" MOUNT4="sysfs /a/sys -t sysfs -o defaults" mkdir $MKSYS mount $MOUNT4 MOUNT5="/dev /a/dev -o bind" mount $MOUNT5 echo "mount $MOUNT2" echo "mount $MOUNT1" cp /sbin/grubinstall /a/sbin/grubinstall chmod 755 /a/sbin/grubinstall chmod +x /a/sbin/grubinstall chroot /a /sbin/grubinstall exit 0 What this does is determines whether the drive is SATA or IDE by looking at diskstats, if it is SATA, it mounts /dev/sda1 & /dev/sda3, if it is IDE, it mounts /dev/hda1 & /dev/hda3, it also creates and mounts all of the auxillary filesystems (proc, sys, dev) The next script which I run in the CentOS environment via chroot is: TYPE= SUBS= if grep -q sda /proc/diskstats then TYPE="sda1" SUBS="s/hda/sda/g" else TYPE="hda1" SUBS="s/sda/hda/g" fi grub-install --no-floppy --recheck /dev/$TYPE sed -i "$SUBS" /boot/grub/menu.lst echo "sed -i $SUBS /boot/grub/menu.lst" sed -i "$SUBS" /etc/fstab echo "sed -i $SUBS /etc/fstab" sed -i "$SUBS" /boot/grub/grub.conf echo "sed -i $SUBS /boot/grub/grub.conf" sed -i "$SUBS" /etc/grub.conf echo "sed -i $SUBS /etc/grub.conf" ls "ls -l /etc/grub.conf /boot/grub/grub.conf /boot/grub/menu.lst" exit 0 By the way /a is the ROOT of the hard drive (freshly imaged) and /a/boot is the boot partition of the hard drive (freshly imaged). This script again enumerates the type of hard disk attached to the system, installs grub on /dev/hda1 or /dev/sda1, modifies /boot/grub/menu.lst /boot/grub/grub.conf /etc/fstab /etc/grub.conf sda>hda hda>sda and so forth. Everything actually works fine; grub is installed; the files are all modified appropriately. The issue comes when the newly imaged system comes up. The first time the system boots up; grub is still configured to boot with root=/dev/sda3; even though NONE of the configuration files mention anything about /dev/sda3. However if I hit 'E' and modify the 'kernel ...' line in the grub editor from the bootloader, and allow it to boot up; the system boots up normally. The STRANGE part; is that after the first time it boots off of /dev/hda3; grub suddenly starts using that EVERY time the system boots; but I cant figure out why I have to first manually change it; and then reboot before it will work. Its almost like the CentOS boot process 'fixes' whatever is wrong with grub; the first time it boots after I run my crazy script on it; but I cant figure out what process during the boot is doing it; or what else I need to do to ensure trouble free auto-installation of CentOS, the reason I am asking you all is because that same script appears to work with a few other distributions. Any advice anyone can give me would be wonderful. Thanks, -Drew

Problem with large tar file.
by CentOS-List＠jamesplace.net 03 Mar '06

03 Mar '06

I have just completed installing CentOS 4.2 (I came over here from Fedora-Land (core-3)). I did this via a fresh install. I tar'd everything to an external drive reinstalled the new stuff and everything is working very well. I've just got one issue. I have a full system backup Backup.tar that has a size of 78,717,880,320. When I issue the command tar -xvf Backup.tar I get only about 111MB of data restored. Basically /root and a couple other odd things of little consequence. I did have a second backup made with cp -pR <stuff> <dest> so I've still got my all my stuff from which I can selectivly restore as needed but I'm wondering why tar didn't work? (While being very glad I made two backups.) Is there a max size limit to a tar file? A bug in tar? Curiosity plagues me. Thanks for any help.

Special thanks to the yumex maintainer Tim Lauridsen for working with the CentOS team to roll in several of our suggested changes into this version of yumex. Tim also backported all the code he has done for yum-2.5.x so we can use it with the 2.4.x series of yum that is included in CentOS-4 ... and Tim has graciously accepted our request to maintain yumex for CentOS. You can install yumex with the command (if you have the extras repo enabled): yum install yumex The following files are uploaded and syncing to the mirrors: i386: yumex-0.99.11-1.0.c4.noarch.rpm src: yumex-0.99.11-1.0.c4.src.rpm

Or you could do this: RAID 1 partition: md0 = 80GB (or whatever the useable total is) Then include md0 in VolGroup00 and create your logical volumes. LV0 = 300MB (/boot) LV1 = 500MB (swap) LV2 = 9.2GB (/) LV3 = 70GB (/home) This way everything is mirrored and everything is in one VG. If you need more space, add another pair of mirrored drives and add the new mirrored device into VolGroup00. Then you can use the space to expand whichever filesystem needs it. I would also advise following the previous poster's advice and leaving a few GB unused so that you aren't forced to add more drives immediately when LV2 fills up faster than you expected. -- Bowie

per port ip routing -- possible?
by Jack Bailey 02 Mar '06

02 Mar '06

Hello, I have a customer who has two Internet connections, cable and DSL, where the cable is much faster than the DSL connection. Is it possible in CentOS 4.2 to use the "ip route" command to direct certain outbound traffic over the faster connection, say http(s) requests? Web searches turn up solutions where NAT is involved, but this guy isn't using NAT. Example configs that show how to load balance multiple connections and ensure symmetric routing all work great, but I don't an example of per-port routing. Any pointers or example commands would be greatly appreciated. Jack

Raid 1 problems
by Mace Eliason 02 Mar '06

02 Mar '06

Hi, I have setup raid on a new server and have found that if I remove one drive it will boot but if I remove the other it says missing OS. I am using two 18.2Gig SCSI drives, using software raid 1. I have it setup with the following drives in this order. /boot swap / all are mirrored between the two drives. I remember a while back that their was a problem with grub would that be the problem here? Why does it work on one drive and not the other? Thanks Mace

Maybe somewhat of a vague question, but what would constitute a moderate and a heavy load as depicted by "top" on any particular machine? I am trying to justify running this machine with near 100% cpu utilization on both, with load averages between 5 and 5 according to top. I don't particularly see any significant slowdown in the running processes, but there is a chance the disk I/O might become an issue if too many things are going on at once. As for actual running processes, it varies between 5 and 9, depending on time of day. Memory is not really an issue, even tho usage tops out around 1.3 - 1.4Gb, and only a small usage =< 500k swap. X does seem to get pretty sluggish at those load levels, and I've thought about dumping back to a text console for most of the runtime, but I like my Xterms and monitoring applets. Sam

Apache ModRewrite
by John Hinton 02 Mar '06

02 Mar '06

Does anybody happen to know if 'for sure' the order in which you list modrewrite rules is the order in which they are processed within a .htaccess file? It does work, but I want to know that it always works. Basically, I have some multiple wildcard rules, where directories can't be hard coded and as it goes deeper into the directories, the more shallow levels interfere with the deeper levels. Thanks, John Hinton

Advice on setting up Raid and LVM
by Fajar Priyanto 02 Mar '06

02 Mar '06

Hi all, I'm setting up Centos4.2 on 2x80GB SATA drives. The partition scheme is like this: /boot = 300MB / = 9.2GB /home = 70GB swap = 500MB The RAID is RAID 1. md0 = 300MB = /boot md1 = 9.2GB = LVM md2 = 70GB = LVM md3 = 500MB = LVM Now, the confusing part is: 1. When creating VolGroup00, should I include all PV (md1, md2, md3)? Then create the LV. 2. When setting up RAID 1, should I make those separated partitions for /, /home, and swap? Or, should I just make one big RAID device? The future purpose of using LVM is I want to be able to expand any partitions that would run out of space into a new disk. Thank you very much. -- Fajar Priyanto | Reg'd Linux User #327841 | Linux tutorial http://linux2.arinet.org 18:35:53 up 4:55, 2.6.15-1.1830_FC4 GNU/Linux Let's use OpenOffice. http://www.openoffice.org

index.php test

greetings i just noticed in another thread the index.php <?php phpinfo(); ?> reference... when you put this on a current i386 centos 4.2 server and hit that page, of course it spews a bunch of info. does anyone have any recommended websites or docs to cross reference or compare this "specific info" against to determine if "obvious" security modifications should be made?? thanks in advance for your help! - rh -- Robert Hanson - Abba Communications Computer & Internet Services (509) 624-7159 - www.abbacomm.net

Dmesg errors logged
by Sam Drinkard 02 Mar '06

02 Mar '06

Along with the discussion of system loading, I remembered something I wanted to add, but just remembered it. I noticed when I logged out, there was a brief flash of a text page (console I presume) that had some things I wanted to investigate further. Given it is a rather lengthly text file, and rather than clutter up the pages here, I stuffed it on my server so anyone wishing to look at it and comment can do so. The file is available at http://wa4phy.net/dmesg.txt Lots of segfaults I know which application they came from, but I don't quite understand about the keyboard errors and emulating rawmode for keycode 240. There also appears to be a few disk errors, both in buffer I/O and a few others I have no idea what they are. At any rate, would appreciate any comments, or if something needs a tweak, that too. Sam

It depends on how Vim recognizes the file. If Vim displays the file as a DOS file, it will hide the ^M and you can't search for it.

Checking out yum localinstall before installing
by Robert Moskowitz 02 Mar '06

02 Mar '06

I want to just see what will happen (ie success, or some dependencies still cannot be met) with: yum localinstall whatever.rpm I ASSuME (I have googled for this, but it is not clear) that localinstall will take the rpm, install it, and go to the yum repro to meet any outstanding dependencies. I just want to test this right now, not actually do it. I want to know what yum would install from the repro as well.

Discrepancies in Anaconda-ks.cfg after kickstart
by Robert Moskowitz 02 Mar '06

02 Mar '06

I am asking this here, that although a kickstart question, may have something to do with the Centos install? I took my Anaconda-ks.cfg from my system, turned it into a ks.cfg and did the install. Everything SEEMS ok, but why? First the partitioning information: ks.cfg supplied: clearpart --all --drives=hda part /boot --fstype ext3 --size=100 --ondisk=hda part / --fstype ext3 --start=14 --end=796 --ondisk=hda part pv.34 --start=797 --end=2303 --ondisk=hda part swap --start=2304 --end=2434 --ondisk=hda volgroup VolGroup00 --pesize=32768 pv.34 logvol /var/opt/scalix --fstype ext3 --name=Scalix --vgname=VolGroup00 --size=8192 anaconda-ks.cfg reports: clearpart --all --drives=hda part /boot --fstype ext3 --size=100 --ondisk=hda part / --fstype ext3 --start=14 --end=796 --ondisk=hda part pv.100000 --start=797 --end=2303 --ondisk=hda part swap --start=2304 --end=2434 --ondisk=hda volgroup VolGroup00 --pesize=32768 pv.100000 logvol /var/opt/scalix --fstype ext3 --name=Scalix --vgname=VolGroup00 --size=8192 what is happening here? Just putting the partitions in different locations, but the same size? Or just reporting differently? Now for packages. ks.cfg %packages @ office @ admin-tools @ editors @ emacs @ system-tools @ text-internet @ dns-server @ gnome-desktop @ dialup @ network-server @ smb-server @ base-x @ web-server @ printing @ kde-desktop @ mail-server @ server-cfg @ development-tools @ graphical-internet system-config-samba system-config-httpd kernel mailman grub kernel-devel system-config-printer -openoffice.org ethereal-gnome -planner openldap-servers krb5-server iptraf -openoffice.org-libs gftp lvm2 freeradius -spamassassin gnome-nettool system-config-printer-gui -sendmail-cf vnc nmap-frontend e2fsprogs -dovecot -openoffice.org-i18n thunderbird and anaconda-ks-cfg: %packages @ office @ admin-tools @ editors @ emacs @ system-tools @ text-internet @ dns-server @ gnome-desktop @ dialup @ network-server @ emacs @ smb-server @ base-x @ web-server @ printing @ kde-desktop @ mail-server @ server-cfg @ development-tools @ graphical-internet kernel grub kernel-devel -openoffice.org -planner -openoffice.org-libs lvm2 -sendmail-cf e2fsprogs -dovecot -openoffice.org-i18n Wow! is the installed list shorter than the 'asked' list. Or is it, perhaps the same way to report the same actions? How would I know?

I thought it took their presence as the hint to > display in DOS mode. A screwed-up text file that doesn't have the ^M's on every line will display this way in Vim. This tends to happen when you transfer a DOS file to unix and then edit it with a program that does not do the conversion for you. The resultant file has ^M at the end of every line except ones you added with the unix editor. -- Bowie

wired network switch to wireless if not active
by Jerry Geis 01 Mar '06

01 Mar '06

All, I am wondering how one PC with a wired and wireless connection can have the wired IP active as long as there is a connection then if the wired connection goes away to then automatically, go wireless, then if wired comes back alive go back to wired. Is that kind of setup possible, if so how. This unit is always on - I just want whichever network is active and faster to be the active connection. The IP addresses for wired would 192.168.1.10 and wireless 192.168.1.20. GW is 192.168.1.1. Thanks, Jerry

Boat loads of: 'localhost kernel: cdrom: open failed.'
by CentOS-List＠jamesplace.net 01 Mar '06

01 Mar '06

Another question: How can a supress these messages from filling up my syslog file? Mar 1 01:31:26 localhost kernel: cdrom: open failed. Mar 1 01:31:57 localhost last message repeated 15 times Mar 1 01:31:59 localhost kernel: cdrom: open failed. Mar 1 01:32:01 localhost kernel: cdrom: open failed. I've got 'noauto' in /etc/fstab. I've also shut down 'autofs' So far the only way I can stop them is to put a cd in the drive. I'd prefer not not have any kind of auto mount system running if that helps. Thanks again. My fstab entries: /dev/hdc /media/cdrom auto pamconsole,fscontext=system_u:object_r:removable_t,exec,noauto,managed 0 0 /dev/scd0 /media/cdrecorder auto pamconsole,fscontext=system_u:object_r:removable_t,exec,noauto,managed 0 0 /dev/scd1 /media/zip auto pamconsole,fscontext=system_u:object_r:removable_t,exec,noauto,managed 0 0

Kickstart is my friend
by Robert Moskowitz 01 Mar '06

01 Mar '06

I just had to change the install command to use ftp. I had to uncomment all of the drive partitioning commands. At first I was confused as to the partitioning failure, then figured out that the partitioning commands were commented out. Most likely to prevent an unwanted disk clearing. Only things: Did stop at the bootup to create a user id. Not a big deal in this case, as I was logging on as root to do a yum update. X was started to give me a progress of the install. So I will want to figure out how to get that in character mode next time. Just on general principles. The time to learn Kickstart was **LESS** than going through a manual install with the network, drive, and apps configuration steps.

Hello People, In my DNS setting I added A record of www for our company website. It works, when you go to http://www.mycompany.com; it resolves and it shows the website content. But in addition, I want also some kind of redirection or mapping (i don't know what you called that) that when people go to http://mycompany.com (without www), it should forward also to the www server. How to do it? Thanks in advance. S.Tux
