libc.so.6(GLIBC_PRIVATE)(64bit) is needed but I cannot find it in CentOS 5.2
by Erez Zilber 13 Aug '08

13 Aug '08

Hi, I hope it's the right list. Anyway, I'm using CentOS 5.2. I wrote a program that uses rtkaio (so my Makefile contains -lrtkaio). The program runs successfully. The problem began when I wanted to create a rpm for my program. I was able to generate a binary rpm, but when I tried to install it, I got the following error: [root@klab002 tmp]# rpm -i /tmp/mypkg-1.0.x86_64.rpm error: Failed dependencies: libc.so.6(GLIBC_PRIVATE)(64bit) is needed by mypkg-1.0.x86_64.rpm I checked the dependencies: [root@klab002 tmp]# rpm -qRp /tmp/mypkg-1.0.x86_64.rpm /bin/bash /bin/sh /bin/sh /bin/sh /usr/bin/python libc.so.6()(64bit) libc.so.6(GLIBC_2.2.5)(64bit) libc.so.6(GLIBC_2.3)(64bit) libc.so.6(GLIBC_PRIVATE)(64bit) libnickel.so()(64bit) libpthread.so.0()(64bit) libpthread.so.0(GLIBC_2.2.5)(64bit) libpthread.so.0(GLIBC_2.3.2)(64bit) rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(PayloadFilesHavePrefix) <= 4.0-1 rtld(GNU_HASH The problem is that librtkaio uses GLIBC_PRIVATE: [root@klab002 tmp]$ nm /lib/rtkaio/librtkaio-2.5.so | grep PRIVATE U __libc_dlopen_mode@@GLIBC_PRIVATE U __libc_dlsym@@GLIBC_PRIVATE U __libc_fatal@@GLIBC_PRIVATE U __libc_pwrite@@GLIBC_PRIVATE w __pthread_clock_gettime@@GLIBC_PRIVATE w __pthread_clock_settime@@GLIBC_PRIVATE U __pthread_unwind@@GLIBC_PRIVATE U _rtld_global@@GLIBC_PRIVATE But I couldn't find where these symbols are defined (e.g. __libc_pwrite@@GLIBC_PRIVATE). The workaround that I found is to add the following line to the spec file: "provides: libc.so.6(GLIBC_PRIVATE)(64bit)" I guess that there should be a better solution for that. Any idea? Thanks, Erez

conntrack-tools and Session syncing
by Dirk H. Schulz 13 Aug '08

13 Aug '08

Hi folks, I have 2 firewalls, setup with Centos 5.2. They are also routers, connected to 2 upstream routers. I have some cases where connections from servers to the internet leave my network via router2 and answers come back via router1. So I added conntrack tools to both routers/firewalls to synchronize the session tables (using ftfw procotol). That works as expected. If e.g. I ping from an inside server to somewhere outside, ICMP request leaves via router2, the answer comes back via router1. conntrack -e on router1 shows this session (as unreplied), BUT the firewall blocks it as new connection - that means iptables does not recognize conntrackd's addition to the session table. Seems that I have a conceptional misunderstanding here - but I do not find anything that could be wrong. Could somebody please help? I am stuck. Any hint or help is appreciated. Dirk

Kerio Mailserver on Centos 5
by dnk 13 Aug '08

13 Aug '08

I was wondering if any of the mail admins on here have used the kerio mail server on centos, and their thoughts on it. My initial testing is going very well - but was hoping for some unbiased opinions (as opposed to asking on the kerio forum) on it's use with centos (5 in particular if possible). THE typical q's - IE performance, issues, etc. Thanks in advance. Dk

Changing boot drives
by MHR 13 Aug '08

13 Aug '08

This is probably a dumb question, but I haven't found anything that clearly describes what I need. My system has 2 IDE (PATA) hard drives and 2 SATA hard drives. /dev/hda is the boot drive, but /dev/sda contains my CentOS installation, including /boot, /, /home and swap. I know for a fact that there is no MBR on /dev/sda because the system refuses to boot from it. I would like to rearrange the boot order to use /dev/sda as the boot device (mainly because I'm probably going to get either another disk drive or both another disk drive and a m/b soon that does not have two IDE connectors (I have two IDE DVD burners) and I'd rather not replace any more than absolutely necessary to accomplish this. So, what is the best way to put a correct MBR that will boot from /dev/sda on /dev/sda if /dev/sda is the first boot device? Thanks. mhr

bind-9.3.4-6.0.2.P1.el5_2 and rrset-order: order 'fixed' not fully implemented
by Keith Christian 13 Aug '08

13 Aug '08

Running CentOS 5.2 with the following BIND update rpm, installed with "yum update" - bind-9.3.4-6.0.2.P1.el5_2. Our master DNS has an rrset-order stanza with "order fixed" entries similar to the following: rrset-order { class IN type A name "abc.foobar123.com" order fixed; class IN type A name "def.foobar123.com" order fixed; class IN type A name "ghi.foobar123.com" order fixed; [ stuff deleted ] } When restarting BIND, I find LOTS of these entries in /var/log/messages: rrset-order: order 'fixed' not fully implemented rrset-order: order 'fixed' not fully implemented rrset-order: order 'fixed' not fully implemented According to this page, BIND can be compiled with the "enabled-fixed-rrset" option to support this. How to determine what switches were used to compile the BIND RPM I downloaded with "yum update?" >From http://www.isc.org/index.pl?/sw/bind/view/?release=9.5.0 : 2362. [cleanup] Make "rrset-order fixed" a compile-time option. settable by "./configure --enable-fixed-rrset". Disabled by default. [RT #17977] Thanks, =========Keith

Please help: The process of am-utils map key lookup
by Robinson Tiemuqinke 13 Aug '08

13 Aug '08

Hi, I am using am-utils(amd binary daemon) to auto mount home directories. the mounting process seems working fine but I am still not understand how the amd map key(s) lookup process works. I've carefully read the am-utils(amd) document at http://am-utils.org/docs/am-utils/am-utils_8.html, especially the chapter "3.2 How keys are looked up" but am still not clear. For example, I'd like to access /home/dumbboy/files/deleteme, what is the key to be used, and how the lookup/match happens? and how the mount operations happens? Thanks a lot. I've attached my configuration files below: $ cat /etc/amd.conf ... auto_dir = /.amd_mnt ... map_type = file search_path = /etc ... [ /home ] map_name = amd.home ... $ cat /etc/amd.home /defaults type:=nfs;sublink:=${key};opts:=rw,intr,tcp,nfsvers=3,vers=3,nosuid,nodev,noresvport,rsize=16384,wsize=16384;fs:=${autodir}/${rhost}${rfs} dumbboy rhost:=home111;rfs:=/0/export/home * rhost:=home110;rfs:=/0/export/home ... Thanks.

mystery process "unit"
by sbeam 12 Aug '08

12 Aug '08

Ok, dumb question. On a certain LAMP server I am seeing in 'ps auxf' a process called "unit" with no arguments or other path info. It has a fairly low pid, 3041, indicating it might have been started soon after reboot (last week). but ps says it was started yesterday, I don't see it on any of 3 other CentOS machines. It is hard to google for such a generic name. So does anyone either know what it is, or how I can find out more about it? Sam

Looking for remote console on iPv6 without security layer
by Robert Moskowitz 12 Aug '08

12 Aug '08

I am looking for a remote console program that I can run over IPv6. I do not need it to supply its own security layer, as I will be running it over HIP (http://infrahip.hiit.fi/) I have discovered that VNCSERVER that comes with Centos does not support IPv6. I would have to pay for a copy of Enterprise VNC from RealVNC for IPv6. I am having strange font problems wiht tightVNC (which is claimed to work with IPv6). FreeNX works with SSH, and it is not clear how to run it without SSH. For my purpose, I do not want to layer multiple security transports. So recommendations???
