Centos 5.4 on Acer Aspire One
by Frank Cox 04 Dec '09

04 Dec '09

I currently have my Acer Aspire One netbook set up with Fedora 11. I would like to change it over to Centos 5.4 if I can. I downloaded the Centos 5.4 i386 livecd image and made a bootable USB flash drive out of it. Unfortunately, when I boot off of that flash drive, Grub (I guess) immediately turns the screen entirely white. If I hit a key I can faintly see the outline of "Press tab to change options" or words to that effect. (It's very faint and hard to read against the white background.) That bit of text rapidly scrolls off of the top of the screen, so I assume that the rest of the boot-up messages are being printed. Hitting Ctrl-Alt-anyFkey does nothing for a while, then every keystroke beeps. I can't get to a text terminal and I never see anything other than a completely white screen. Am I doing something wrong? Fedora 11 works fine on this machine, and I installed that from a livecd. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com

Getting EXTERN.h, perl.h, etc
by Charles E Campbell Jr 03 Dec '09

03 Dec '09

Hello: I have a Fedora Core 11 system at home (Centos 5.2 at work). I'd like to build vim with huge and perl. This works under Centos, but fails at home: no EXTERN.h or perl.h (and, presumably, other things). So: is there a yum package I should be downloading, and if so, which one? (both the home computer and the work computer are 64-bit systems) Thank you, Chip Campbell -- someday I'll have a good signature, I'm sure of it...

by mcclnx mcc 03 Dec '09

03 Dec '09

I have some batch JOBs migrate from CEBTOS 5.3 to CENTOS 5.4 server. Those batch files start on "#!/bin/csh -v". Those batch files run good under CENTOS 5.3. on CENTOS 5.4 batch jobs still run good but end of batch priocess it will show "history". Does anyone know why? Thanks. ___________________________________________________ 您的生活即時通－溝通、娛樂、生活、工作一次搞定！ http://messenger.yahoo.com.tw/

Kerberos + NFSv4 difficulties
by Dan Burkland 03 Dec '09

03 Dec '09

Hey All, I recently have been trying to setup an NFSv4 share that utilizes Kerberos. My experience in general with NFS is very slim however I feel like I am very close to getting this project completed. Currently I have the following things in place: 1) NFS server nfs.example.net (VM#2) - Running CentOS 5.4 with all of the latest updates and NFS-related packages 2) Kerberos KDC running on Kerberos.example.net (VM#1) - Running CentOS 5.4 with all of the latest updates 3) NFS client nfs-client.example.net (VM#3) - Running CentOS 5.4 with all of the latest updates Before I give you the error message I receive when I enable NFS, I'll first describe my setup process. 1) Verified Kerberos works on all machines by attempting a kinit testuser which worked properly. 2) Verified that the clocks on all machines represent the same time (synced using a local NTP server) 3) Created a service principle for nfs.example.net by performing the following commands on the nfs.example.net machine: - (Performed on NFS server) a. kadmin (Logged in as an admin principle) b. addprinc -randkey nfs/nfs.example.net c. ktadd -e des-cbc-crc:normal nfs/nfs.example.net d. quit e. kinit nfs/nfs.example.net -k -t /etc/krb5.keytab f. klist to verify 4) Edited /etc/idmapd.conf with the following changes: - (Performed on NFS server) a. changed Nobody-{User,Group} to nfsnobody b. changed Domain to nfs.example.net 5) Mkdir /nfs/ - (Performed on NFS server) 6) Added the following to /etc/exports - (Performed on NFS server) a. /nfs gss/krb5p(rw,sync,fsid=0) 7) exportfs -rv - (Performed on NFS server) 8) Verified all relevant nfs services were stopped - (Performed on NFS server) 9) Uncommented and made the following changes to /etc/sysconfig/nfs - (Performed on NFS server) a. MOUNTD_NFS_V1="no" b. MOUNTD_NFS_V2="no" c. RPCNFSDARGS="-N 2 -N 3 -U" d. SECURE_NFS = "yes" 10) /etc/init.d/portmap start; /etc/init.d/rpcidmapd start; /etc/init.d/nfs start - (Performed on NFS server) 11) And I receive the following output when the nfs service starts: a. Starting RPC svcgssd: FAILED b. Starting NFS Services: OK c. Starting NFS quotas: OK d. Starting NFS daemon: NFSD: Using /var/lib/nfs/v4recovery as the NFSv4 state recovery directory e. NFSD: starting 90-second grace period f. Starting NFS mountd: OK 12) I then checked /var/log/messages to find the following log entries: a. Dec 2 12:16:51 nfs rpc.svcgssd[6018]: ERROR: GSS-API: error in gss_acquire_cred(): Unspecified GSS failure. Minor code may provide more information - No principal in keytab matches desired name b. Dec 2 12:16:51 nfs rpc.svcgssd[6018]: Unable to obtain credentials for 'nfs' c. Dec 2 12:16:51 nfs rpc.svcgssd[6018]: unable to obtain root (machine) credentials d. Dec 2 12:16:51 nfs rpc.svcgssd[6018]: do you have a keytab entry for nfs/<your.host>@<YOUR.REALM> in /etc/krb5.keytab? I seem to be stuck at this point and would appreciate your insight. Thank you, Dan

Re: [CentOS] Small proxy appliance hardware
by Chuck Munro 03 Dec '09

03 Dec '09

Regarding a small proxy appliance, my thanks to those who responded either on this list or by direct email. We are going to get one of the little Acer AspireRevo 3610 boxes and give it a try. It's small, quiet, runs cool, and has more than enough resources to handle our CentOS proxy application. It's a shame that we have to trash the Windows-7 install (a waste of money) but that's life. The only unanswered question is with regard to an external USB wired network adapter, so we'll have to go by the data on the various manufacturers' web sites about Linux support. Has anyone tried the Belkin USB2/Gbit, the D-Link DUB-E100 or the Linksys USB300M devices? Which adapter chips to they use (in other words, which driver)?

LDAP for central authentication?
by Scott Ehrlich 03 Dec '09

03 Dec '09

I have the following on a network: 1) RHEL 5.0 Server acting as NIS and Samba domain controller 2) CentOS 5.x machines on NIS network 3) Win XP machines on Samba domain When I create an account for someone, I need to first type adduser new_person -d /home/new_person then passwd new_person, then cd /var/yp and make. Then smbpasswd -a new_person. Thus, two different databases. On another network, I have separate XP and Linux (CentOS 5.x, RHEL 5.x, and Suse) systems. No Samba, no NIS. Can I still set up a central LDAP directory for a single account database? For the NIS+Samba case, can I merge both credential files into a central database using LDAP? I would also want to control password length, complexity, aging, and other things. What is the best way to do this? Thanks. Scott

Fedora 11 i386 Evolution address book --> CentOS 5.4 x86_64
by David McGuffey 03 Dec '09

03 Dec '09

Finally moved my home desktop from Fedora to CentOS. My spouse was unhappy with me upgrading from F9-->F10-->f11 etc and wanted something more stable. I built a second machine which is now running in parallel to the old F11 desktop. I moved my data (mail and files) from the F11 box to the CentOS 5.4 box. I used tar to move everything. Mail and files transferred A-OK...but the Evolution address book did not. Any tips on getting the old /home/.../.evolution/addressbook which worked with the version of Evolution on the new machine with an older version of Evolution? BTW, on CentOS, I cannot add new addresses to the address book. User_id on the new machine is the same as on the old machine, so perms should not be the problem. I checked the selinux context and it is the same as everything else in /home If I do a forced reinstall of Evolution would it mess up the mail files? DaveM
