CentOS5 running very slowly on a core 2 duo with 4 GB RAM
by israel.garcia＠cimex.com.cu 21 Aug '08

21 Aug '08

Hi, I've installed CentOS5.2 on an INTEL Core 2 Duo (Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz), 4 GB RAM (MemTotal: 4072176 kB) and my system gets sevarel minutes to startup, specially on udev daemon. Once the system is UP, every command I run gets 100% CPU and every is very slowly at the point yum -y update never ends. The system installed by default this kernel 2.6.18-53.el5PAE. I would like to know what's wrong with my server. Do I have to install another kernel? Can you help me? More details of my server: [root@netreporter-test ~]# uname -a Linux netreporter-test 2.6.18-53.el5PAE #1 SMP Mon Nov 12 02:55:09 EST 2007 i686 i686 i386 GNU/Linux [root@netreporter-test ~]# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz stepping : 11 cpu MHz : 2331.000 cache size : 4096 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 : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc pni monitor ds_cpl vmx smx est tm2 cx16 xtpr lahf_lm bogomips : 4667.95 processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz stepping : 11 cpu MHz : 2331.000 cache size : 4096 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 : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc pni monitor ds_cpl vmx smx est tm2 cx16 xtpr lahf_lm bogomips : 4665.47 [root@netreporter-test ~]# cat /proc/meminfo MemTotal: 4072176 kB MemFree: 3871428 kB Buffers: 14224 kB Cached: 145872 kB Thanks in advance Israel.

Disabling IPv4
by Robert Moskowitz 21 Aug '08

21 Aug '08

I want to seriously work with IPv6 and not have stray IPv4 functions messing with me. So in /etc/sysconfig/network, I commented out NETWORKING=yes. I have NETWORKING_IPV6=yes. In /etc/sysconfig/network-scripts I altered ifcfg-eth0, setting BOOTPROTO=none. That was enough for eth0 to only have IPv6 working on it (have IPV6INIT=yes and IPV6_AUTOCONF=yes). But lo had IPv4. So I commented out all of the IPV4 lines in ifcfg-lo. Still have IPv4 on lo. How do I disable that? Yes, I did an service network restart after changing ifcfg-lo.

qt3.3 is default in environment, I want it to be qt4
by Paul Johnson 20 Aug '08

20 Aug '08

At the current time, the environment is using qt3 values, as in $ env | grep QT QTDIR=/usr/lib/qt-3.3 QTINC=/usr/lib/qt-3.3/include QTLIB=/usr/lib/qt-3.3/lib $ env | grep PATH PATH=/usr/lib/qt-3.3/bin:/usr/kerberos/bin:/usr/lib/ccache:/usr/local/bin:/bin:/usr/bin:/home/pauljohn/bin I also have QT4 installed, and I want programs to find those libraries and include files instead of these ones. As far as I can tell, Centos uses the pkgconfig framework to let programs ask about the preferred libraries. $ /usr/bin/pkg-config --variable=prefix qt-mt /usr/lib/qt-3.3 And I see the file that pkgconfig is reading here: $ cat /usr/lib/pkgconfig/qt-mt.pc prefix=/usr/lib/qt-3.3 exec_prefix=${prefix} libdir=${prefix}/lib includedir=${prefix}/include qt_config=qt warn_on release incremental link_prl nocrosscompiler dlopen_opengl minimal-config small-config medium-config large-config full-config styles tools kernel widgets dialogs iconview workspace inputmethod network canvas table xml opengl sql styles tools kernel widgets dialogs iconview workspace network canvas table xml opengl sql release dll thread largefile stl ipv6 system-mng mng system-jpeg jpeg system-png png gif system-zlib nis cups bigcodecs x11sm xshape xinerama xcursor xrandr xrender xftfreetype xkb inputmethod dylib create_prl link_prl qt warn_on depend_includepath qmake_cache x11 x11inc create_libtool create_pc moc x11lib I do not know for sure if the environment is accessing the pkgconfig setup to get the information it has, but I know for sure that configure scripts are using pkg-config to ask which qt should be used. Each time I build a program, then, I have to reset QTDIR, QTLIB, QTINC, and the PATH. I guess my question is 1. is 3.3 preferred for some reason by the Centos framework? If a program looks for "qt-mt.pc", does that mean it wishes to use qt3.3 rather than qt4? 2. aside from just hand editing that file and changing the prefix to /usr/lib/qt4, how do I change the preferred QT. The qt4-devel package gives its own set of pc files, but I can't tell how they can be used in the environment.. -- Paul E.

Unknown mail transport error
by Anne Wilson 20 Aug '08

20 Aug '08

I've just signed a bunch of keys using the caff tools. A few minutes ago they started bouncing back at me, with the above error. Received: by anne-wireless.lydgate.net (Postfix, from userid 500) id CA4B230EF7; Wed, 20 Aug 2008 11:15:39 +0100 (BST) MIME-Version: 1.0 Subject: Your signed PGP key 0x2C4F325BFF906D62 User-Agent: caff 0.0.0.309 - http://pgp-tools.alioth.debian.org/ X-Mailer: MIME-tools 5.425 (Entity 5.425) Sender: anne <anne(a)anne-wireless.lydgate.net> Content-Type: multipart/encrypted; protocol="application/pgp-encrypted"; boundary="----------=_1219227339-4052-1" I used the same tools last year without problems, but obviously something is different this year. Can anyone suggest what's wrong, and what I can do about it? Anne

Best way to migrate a server?
by Kevin Thorpe 20 Aug '08

20 Aug '08

I was just wondering what recommendations you have on migrating a CentOS 5 install between servers? I've done similar in the past by setting up a minimal install in the new server, use tar to copy over the old install and reboot. I was thinking of rsync this time. Is that an acceptable thing to do or have I missed something important? thanks
