Audit logs source of account triggering it.
by Gregory Machin 10 Apr '13

10 Apr '13

Hi. The auditd logs are full of lines referencing 28756E6B6E6F776E207573657229 , but I can't identify this account type=USER_LOGIN msg=audit(1364926580.306:249814): user pid=22565 uid=0 auid=4294967295 ses=4294967295 msg='op=login acct=28756E6B6E6F776E207573657229 exe="/usr/sbin/sshd" hostname=? addr=127.0.0.1 terminal=ssh res=failed' What would typically cause this ? There are no other references in any of the other logs to 28756E6B6E6F776E207573657229 and its to long for our typical UID / GID . Thanks G

How to determine 64 vs 32 bit processor
by Robert Moskowitz 10 Apr '13

10 Apr '13

I have been tied up with other work and Holidays. Now back to some server work that is long overdue. I lost an old server yesterday so it is crunch time. I believe my new platform is suppose to be an x86_64. The order form says 64 bit. I booted Centos 6.3 i386 liveCD to check the system out before an install. uname -i reports i386 dmidecode -t processor reports Characteristics of 64 bit capable. The processor is an AMD duo-core Opteron. I thought that in a prior thread I found that booting with an i386 live CD and using uname would confirm the processor type. It seems not. I am going to go with the various evidence and start a x86_64 install, but what is with uname? thanks

How to patch a CentOS6 kernel
by Michael Mol 10 Apr '13

10 Apr '13

So I have a couple patches supplied to me by upstream in relation to a kernel bug[1], but I can't figure out how to patch the kernel. The CentOS wiki page discusses retrieving the kernel source[2], but doesn't describe how to apply patches. Instructions I've found apply to CentOS5, and RH has changed their kernel packaging since then. I've been banging my head on this off and on for quite a while, now. I've mucked with Gentoo and Debian packaging, but kernel RPMs are a new one for me... [1] http://bugs.centos.org/view.php?id=6343 [2] http://wiki.centos.org/HowTos/I_need_the_Kernel_Source

I have centos-release-5-9.el5.centos.1 and fail2ban-0.8.7.1-1.el5.rf installed with selinux disabled The errors I get are: INFO Creating new jail 'sasl-iptables' fail2ban.comm : WARNING Invalid command: ['add', 'sasl-iptables', 'polling'] I tried gemin against polling but I get the same error. The strange thing is that if I enable ssh action, starts with no problem.

fsck - anyway to increase verbosity to show point in process
by Max Pyziur 10 Apr '13

10 Apr '13

Greetings, I'm running CentOS 5.x on one ancient but reasonably reliable machine: root@leeloo ~> uname -a Linux leeloo 2.6.18-308.24.1.el5 #1 SMP Tue Dec 4 17:42:30 EST 2012 i686 i686 i386 GNU/Linux root@leeloo ~> cat /proc/cpu cat: /proc/cpu: No such file or directory root@leeloo ~> cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 11 model name : Intel(R) Pentium(R) III CPU family 1400MHz .. I am running some fsck's on some of the larger drives (750GB and 2TB) that are used for backups. There is a verbosity flag (-V); but because of the size of the drives along with slowness of the processor, the process is taking a long time. And there is no indication how much of the process has been completed (nothing like a %tage indicator), at least the way that I am running it. Is this expected, or is there some way of amping up the feedback? Much thanks, Max Pyziur pyz(a)brama.com
