tasks bouncing between CPUs
by Florin Andrei 29 Jan '07

29 Jan '07

I've a dual core system (see /proc/cpuinfo at the end) running CentOS 4.4 (fully up-to-date) and I'm running a PHP script that's parsing files and dumping the results into a database. Software versions: # rpm -q php php-4.3.9-3.22 # rpm -q MySQL-server-standard MySQL-server-standard-5.0.27-0.rhel4 # uname -srvmpio Linux 2.6.9-42.0.3.ELsmp #1 SMP Fri Oct 6 06:21:39 CDT 2006 i686 athlon i386 GNU/Linux The thing is, the script process and the MySQL process seem to arbitrarily jump from one CPU to another. That would be fine, I guess, but sometimes both processes are on the same CPU core. Is there a way to keep these processes separate (each one on a different core), or make them "sticky" w.r.t. the CPU cores? # cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 35 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 4800+ stepping : 2 cpu MHz : 2412.035 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext lm 3dnowext 3dnow pni bogomips : 4825.57 processor : 1 vendor_id : AuthenticAMD cpu family : 15 model : 35 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 4800+ stepping : 2 cpu MHz : 2412.035 cache size : 1024 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext lm 3dnowext 3dnow pni bogomips : 4821.52 -- Florin Andrei http://florin.myip.org/

UFS (Unix File System) support
by Jordi Espasa Clofent 29 Jan '07

29 Jan '07

Hi, I need to mount a UFS (Unix File System) partition from an external device (ie, live cd). I've seen the kernel-2.6.x-x.x.x.xxx.plus.c4 has UFS support and I've several questions about: ¿How I know what FS are supported by my kernel? ¿Is CentOS LiveCD edition builded with UFS support? ¿Is there another way to get UFS support without the complete installation of a new kernel? Thanks.

Where can I get samba-vscan from?
by Rakhesh Sasidharan 29 Jan '07

29 Jan '07

Hi there! Am using CentOS 4.4. Have installed Samba and ClamAV. My understanding is that there's a vfs module (samba-vscan) which I have to install for Samba to virus scan its shares. Where can I get it from? I tried stuff like "yum install samba-vscan" etc but it doesn't seem to be there in the repos. I have RPMForge and the usual CentOS repos enabled. Is this something I have to install from the sources or can I get a binary package from someplace? Thanks, Rakhesh

Permission error (Mantis bugtracker)
by Jordi Espasa Clofent 28 Jan '07

28 Jan '07

Hi all, I've installed mantis.noarch and mantis-config-httpd.noarch packages. The problem is I always get the same error in Apache:. You don't have permission to access /mantis on this server. It's curious 'cause: * I work in localhost mode and I've running drupal site and phpMyAdmin without problems. So, Apache works fine. * I've created mantis ddbb according the docs without any problems (mysql -u<user> ... bla bla).In fact, the database is available from phpMyAdmin and from mysql client. * I've check the httpd.conf file and it includes the line Include conf.d/*.conf so the /etc/httpd/conf.d/mantis.conf is available. * I've created the config_ini.php file and modified it with correct database parameters. * I've cheched (and fixed) the mantis.conf file sintaxis. More info: [root@localhost ~]# rpm -qi mysql | grep Version Version : 5.0.22 Vendor: http://centos.org [root@localhost ~]# rpm -qi httpd | grep Version Version : 2.0.52 Vendor: CentOS [root@localhost ~]# rpm -qi php | grep Version Version : 5.1.6 Vendor: CentOS TIA.

Problems with building a complete kernel
by Mark Hull-Richter 28 Jan '07

28 Jan '07

I have a plain vanilla Centos source (not 100% sure where we got it from), but I can't seem to get a build that installs correctly. I tried the method described at http://wiki.centos.org/HowTos/Custom_Kernel, but rpm doesn't like the output file, and even if I install it with -F, nothing seems to happen - no new kernel, now initrd, nothing. When I tried following the directions in the README file that came with the source, I built the kernel just fine, but the instructions then go on to describe how to modify LILO to make the install work, and my boot loader is GRUB - not sure how to reconcile those two. So, I built yet another kernel (rpm) following the guide at http://www.howtoforge.com/kernel_compilation_centos, and the rpm built just fine, but when I run mkinitrd, it complains that I don't have the ahci module in my kernel. The only reference I have found to ahci is in my boot setup, and it is already enabled, so, once again, I am stuck. Anyone have any ideas here? I'm running Centos 2.6.9-42.0.3ELsmp on a Dell Precision 390 (P4/HT 3GHz, 2Gb mem, ATI FireGL 4700, 160Gb SATA, ... Thanks (again).

Problems with minicom on CentOS 4.4
by Jarod Wang 28 Jan '07

28 Jan '07

Hi all I am a newcomer of this ML. And I installed CentOS a couple of hours ago on my i386 box because it is said that CentOS is a community based binary distro of RHEL. Before that I used to use RH9(it is quite out of date for my newly upgraded PC) as my host environment to work on embedded systems. The installation procedure went smoothly and after that everything looked functional, however, I found that the minicom had a problem - When I started it in GNOME terminal window using “minicom -s” for the time, the program halted like this: [root@localhost ~]# minicom -s minicom: WARNING: configuration file not found, using defaults And then I could not input any commands, I had to close the GNOME terminal window manually. I can remember it clearly that this command(minicom -s) should start the configuration procedure of minicom in RH9. Then I tried to reinstall the minicom program by using “yum remove minicom” and then “yum install minicom”, but the problem remains. Could some tell me how to solve this problem? Any hints would be highly appreciated. P. S. the version of my minicom program is: [root@localhost ~]# minicom --version minicom version 2.00.0 (compiled Feb 21 2005) Best regards, Jarod Wang ---- Oracle Asia R&D Center, Shenzhen, P. R.
