pam_succeed_if
by Daniel De Marco 10 Jun '11

10 Jun '11

Hi, The default system-auth file for PAM on CentOS has the following auth section: auth required pam_env.so auth sufficient pam_unix.so nullok try_first_pass auth requisite pam_succeed_if.so uid >= 500 quiet auth required pam_deny.so What's the use of the pam_succeed_if line? It will only be reached if the pam_unix doesn't succeed and from my understanding it will prevent system accounts from logging in. Is it useless or am I missing something? Thanks, Daniel.

Cloning LVM
by Christopher Hearn 10 Jun '11

10 Jun '11

I have a workstation with two separate drives set up with LVM. I'm buying an LSI RAID controller to set up mirrored drives. I'd like to clone the existing drives over to the new mirrored drives somehow, but not sure the best way to do it. The original drives & their respective replacements are all identical in size (250GB + 1TB). I thought about using Clonezilla but wasn't sure how LVM would handle the /dev devices changing. Any suggestions? Thanks, Chris

Vim scripting - cursor motion
by Jussi Hirvi 10 Jun '11

10 Jun '11

I am working on my first vim script. The script is supposed to do some find/replace on a file, then save the file with a new name and quit vim. I will save the script in a file and then call it from a bash script like this: vim path-to-the-file -s path-to-my-script Maybe I have not found the right resources. I can find/replace with expressions that are similar to those I use manually, for example: :% s/\t/","/g Then I should add something to the beginning of file (line 1, char 1). And append something to the end of the file (last line, last char). But I cannot find a way to do this. Should I move the cursor (and how?), or what? - Jussi

High system load but low cpu usage
by Emmanuel Noobadmin 10 Jun '11

10 Jun '11

I'm trying to figure out what's causing an average system load of 3+ to 5+ on an Intel quad core. The server has with 2 KVM guests (assigned 1 core and 2 cores) that's lightly loaded (0.1~0.4) each. Both guest/host are running 64bit CentOS 5.6 Originally I suspected maybe it's i/o but on checking, there is very little i/o wait % as well. Plenty of free disk space available on all physical drives and memory sufficient for the usage with barely any swap in use. While performance/responsiveness of the host and guests doesn't seem to be affected, I'm still concerned about this odd load figures. Would appreciate it if anybody can suggest what else I should be looking at? Output of various commands on the host: Top === top - 15:15:39 up 5 days, 8:48, 1 user, load average: 4.76, 4.18, 4.43 Tasks: 210 total, 1 running, 209 sleeping, 0 stopped, 0 zombie Cpu(s): 4.1%us, 2.5%sy, 0.0%ni, 76.4%id, 17.0%wa, 0.0%hi, 0.1%si, 0.0%st Mem: 3759496k total, 2813076k used, 946420k free, 357300k buffers Swap: 8193016k total, 5648k used, 8187368k free, 736640k cached free -m ====== total used free shared buffers cached Mem: 3671 2750 921 0 348 719 -/+ buffers/cache: 1682 1989 Swap: 8000 5 7995 vmstat 3 ====== procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu----- r b swpd free buff cache si so bi bo in cs us sy id wa st 2 0 5648 949072 357096 735788 0 0 105 50 17 22 2 1 95 1 0 0 0 5648 949428 357104 735788 0 0 44 2682 14142 14697 6 4 84 6 0 0 0 5648 949304 357104 735788 0 0 1 324 14047 14753 2 1 96 1 0 1 1 5648 946916 357104 735788 0 0 0 215 14410 14496 2 2 90 6 0 0 0 5648 946520 357104 735788 0 0 23 267 13703 14664 2 2 91 6 0 sar === 02:40:01 PM CPU %user %nice %system %iowait %steal %idle 02:50:01 PM all 2.17 0.00 2.18 4.30 0.00 91.35 03:00:01 PM all 2.47 0.00 2.23 3.57 0.00 91.73 03:10:01 PM all 2.29 0.00 2.07 3.77 0.00 91.87 03:20:01 PM all 2.63 0.00 2.07 3.28 0.00 92.03 Average: all 2.39 0.00 1.95 4.77 0.00 90.89

NTLM auth fails after upgrade to centos 5.6
by Tom Diehl 09 Jun '11

09 Jun '11

Hi, I upgraded a working centos5.5 with squid using ntlm auth to centos 5.6 today. After doing so squid failed to authenticate. Downgrading samba3x to samba3x-3.3.8-0.52.el5_5.2 got things working again. In the squid config I have, auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp in the squid config and this was working until the upgrade. testparm shows no errors and the logs do not indicate a problem except that authentication fails. With samba3x-3.5.4-0.70.el5_6.1.x86_64 installed the following command fails: /usr/bin/ntlm_auth --username=myuser with the following error: [2011/06/09 10:21:19.538041, 2] winbindd/winbindd_pam.c:2001(winbindd_dual_pam_auth_crap) NTLM CRAP authentication for user [mydomain]\[myuser] returned NT_STATUS_INVALID_HANDLE (PAM: 4) with samba3x-3.3.8-0.52.el5_5.2 I get the following: (indy pts3) # /usr/bin/ntlm_auth --username=myuser password: NT_STATUS_OK: Success (0x0) (indy pts3) # [2011/06/09 18:18:30, 2] passdb/pdb_ldap.c:init_sam_from_ldap(571) init_sam_from_ldap: Entry found for user: myuser [2011/06/09 18:18:30, 2] auth/auth.c:check_ntlm_password(308) check_ntlm_password: authentication for user [myuser] -> [myuser] -> [myuser] succeeded Has anyone else seen this behavior?

Re: [CentOS] Looking for gfs2-kmod SRPM
by centoslistbrian＠nym.hush.com 09 Jun '11

09 Jun '11

This is kind of figured out now. The actual RPM I'm using is from the debuginfo repo here: http://debuginfo.centos.org/5/x86_64/gfs2-kmod-debuginfo-1.92-1.1.el5_2.2.x… The contents of the RPM are identical to the RedHat RPM: http://ftp.redhat.com/pub/redhat/linux/enterprise/5Server/en/os/x86_64/Debu… The problem here is that the source included in the debuginfo RPM does not match the binary. When running the binary, I get "f:q" in my gfs2_tool lockdump output, which definitely cannot happen given the source code in the RPM. It appears that this patch has been applied during compilation. https://www.redhat.com/archives/cluster-devel/2011-May/msg00037.html But the patch is not applied to the source code included. Clearly this is not a CentOS issue as the RedHat RPM is wrong too, so this is just informational to close out the issue.
