20 Oct '10

Hi, I have a project that is a library that links against libresolv, It works fine on recent distros: Ubuntu 10.x Fedora 13, Mandriva 2010.1 but on Centos 5.x I get the following errors glibc installed is: glibc-2.5-18.el5_1.1 g++ -DHAVE_CONFIG_H -I. -I./include -I/usr/include/postgresql -O3 -ansi -Wall -Wno-deprecated -D_FORTIFY_SOURCE=0 -MT testUpLog.o -MD -MP -MF .deps/testUpLog.Tpo -c -o testUpLog.o testUpLog.cc mv -f .deps/testUpLog.Tpo .deps/testUpLog.Po /bin/sh ./libtool --tag=CXX --mode=link g++ -O3 -ansi -Wall -Wno-deprecated -D_FORTIFY_SOURCE=0 -L/usr/lib64 -L/lib64 -L/usr/lib64/mysql -o testUpLog testUpLog.o libUpTools.la -lpq -lmysqlclient -lssl -lpthread libtool: link: g++ -O3 -ansi -Wall -Wno-deprecated -D_FORTIFY_SOURCE=0 -o .libs/testUpLog testUpLog.o -L/usr/lib64 -L/lib64 -L/usr/lib64/mysql ./.libs/libUpTools.so -lpq -lmysqlclient -lssl -lpthread ./.libs/libUpTools.so: undefined reference to `__ns_name_uncompress' ./.libs/libUpTools.so: undefined reference to `__ns_initparse' ./.libs/libUpTools.so: undefined reference to `__ns_parserr' collect2: ld returned 1 exit status make[1]: *** [testUpLog] Error 1 make[1]: Leaving directory `/tmp/UpTools-8.5.3' make: *** [check-am] Error 2 library.la file contains: dlname='libUpTools.so.0' library_names='libUpTools.so.0.0.0 libUpTools.so.0 libUpTools.so' old_library='libUpTools.a' inherited_linker_flags='' dependency_libs=' -L/usr/lib64 -L/lib64 -L/usr/lib64/mysql -lpq -lmysqlclient -lssl -lpthread' weak_library_names='' current=0 age=0 revision=0 installed=no shouldnotlink=no dlopen='' dlpreopen='' libdir='/usr/lib' You can read my files on pastebin.com *configure.ac http://pastebin.com/hs5q21Rq *Makefile.am; http://pastebin.com/KW1sGZve Thanks in advance -- -- Sergio Belkin http://www.sergiobelkin.com Watch More TV http://sebelk.blogspot.com Sergio Belkin -

Can we use gstreamer bad, ugly and ffmpeg packages ( installed using binary rpms) without any legal problems
by praveenya kumar 20 Oct '10

20 Oct '10

Hi We are using centos 5.3 Operating system. It comes with basic gstreamer setup including gstreamer, gstreamer-tools, gstreamer-plugins-base and gstreamer-plugins-good packages. To support different media formats we had to install gstreamer-plugins-bad, gstreamer-plugins-ugly and gstreamer-plugins-ffmpeg from third party repository like rpmfusion as centos repository is not providing these packages. My question is, Can we use these packages ( bad, ugly and ffmpeg) without any legal or licensing issues? If No, Please tell the legal way of using them. thanks G Praveen

OpenLDAP, PAM, GDM Configuration on CentOS 5.5
by Trevor T Kates 20 Oct '10

20 Oct '10

Hello: I am currently establishing a LDAP installation for my department and hope to get a little help on some of the finer details of the configuration. OpenLDAP 2.3.43-12 is currently installed, configured and running on one of my servers with a few client installations querying authentication information from it. The ppolicy schema has been added to the configuration and a password policy has been added to the directory under "cn=default,ou=Policies,dc=domain,dc=com". Users are able to authenticate properly on the client machines to at least login; however, I have been unable to achieve the following functions: - Force user to change password on first login and display a prompt from gdm to facilitate the change - Lock user account from access and display a message from gdm to that fact These workstations are being used in a restricted mode so that the user may only work within X and may not open a terminal. Any help with this particular problem would be appreciated. Thanks. ________________________________________________________ Trevor T.

Increased memory usage between 4.8 and 5.5
by Bryan Stillwell 20 Oct '10

20 Oct '10

I'm running into a memory problem when trying to switch some web servers that are running centos4.8/x86_64 to centos5.5/x86_64. The new servers running centos5.5 are using a decent amount more memory than the centos4.8 servers. Here's an example from top: --- centos 5.5 --- $ uname -a Linux ws51 2.6.18-194.17.1.el5 #1 SMP Wed Sep 29 12:50:31 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 7799 nobody 16 0 348m 101m 43m S 0.0 2.6 1:10.91 httpd 20285 nobody 15 0 340m 94m 43m S 0.0 2.4 1:11.36 httpd 31734 nobody 15 0 340m 91m 41m S 0.0 2.3 1:13.52 httpd 8904 nobody 15 0 341m 89m 39m S 0.0 2.3 0:35.28 httpd 7353 nobody 15 0 336m 87m 42m S 0.0 2.2 1:21.17 httpd 26097 nobody 15 0 333m 87m 43m S 0.0 2.2 1:28.84 httpd 20765 nobody 15 0 335m 86m 42m S 0.0 2.2 0:48.50 httpd 23299 nobody 15 0 334m 86m 42m S 0.0 2.2 1:13.35 httpd --- centos 4.8 --- $ uname -a Linux ws89 2.6.9-89.0.28.ELsmp #1 SMP Fri Aug 20 16:11:39 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 25117 nobody 16 0 244m 57m 41m S 0.0 1.5 0:58.23 httpd 21318 nobody 15 0 240m 53m 41m S 0.0 1.3 0:53.25 httpd 18517 nobody 16 0 239m 51m 41m S 0.0 1.3 0:41.97 httpd 10383 nobody 15 0 238m 50m 40m S 0.0 1.3 0:31.07 httpd 29560 nobody 16 0 239m 49m 39m S 0.0 1.3 0:40.39 httpd 32459 nobody 16 0 238m 49m 40m S 0.0 1.3 0:23.07 httpd 8441 nobody 15 0 238m 48m 39m S 0.0 1.2 0:22.87 httpd 1350 nobody 15 0 238m 48m 39m S 0.0 1.2 0:29.83 httpd The versions of both apache and php I have installed are the same between the two releases, so I can't imagine that being the problem. I've also tested newer versions and it doesn't seem to make a difference. I've looked into this quite a bit and below is what I've figured out so far. Looking at the output of running 'pmap -x <pid>' shows most of the libraries in 5.5 are using 2044K or 2048K of memory, but in 4.8 they're all using 1024K or less. Example: --- centos 5.5 --- 00002b37c3248000 16 16 0 r-x-- libnss_dns-2.5.so 00002b37c324c000 2044 0 0 ----- libnss_dns-2.5.so 00002b37c344b000 4 4 4 r---- libnss_dns-2.5.so 00002b37c344c000 4 4 4 rw--- libnss_dns-2.5.so --- centos 4.8 --- 0000002aa4a5e000 16 - - - r-x-- libnss_dns-2.3.4.so 0000002aa4a62000 1020 - - - ----- libnss_dns-2.3.4.so 0000002aa4b61000 4 - - - r---- libnss_dns-2.3.4.so 0000002aa4b62000 4 - - - rw--- libnss_dns-2.3.4.so This seems to be explained by an increase in ELF_MAXPAGESIZE between the two releases according to this page: http://www.greenend.org.uk/rjk/2009/dataseg.html Another oddity I found that was only in centos 5.5 was a lot of heap memory being marked as Private_Dirty according to /proc/<pid>/smaps: 2b37c9826000-2b37cc4ca000 rw-p 2b37c9826000 00:00 0 [heap] Size: 45712 kB Rss: 45424 kB Shared_Clean: 0 kB Shared_Dirty: 1580 kB Private_Clean: 0 kB Private_Dirty: 43844 kB Swap: 0 kB Pss: 43913 kB The highest amount of Private_Dirty showing up on 4.8 is just 1628 kB. Does anyone have any ideas on why 5.5 is using so much memory per httpd process than it does in 4.8? I have 100+ machines I want to upgrade, but that'll have to wait until I figure out why apache uses so much more memory in 5.5... Thanks in advance, Bryan

Who maintains php-pgsql package? I want to ask about using PostgreSQL 8.4 library instead of PostgreSQL 8.1.
by Aleksey Tsalolikhin 19 Oct '10

19 Oct '10

How do I find out who is the maintainer of the php-pgsql package, please? I want to request upgrade from underlying postgresql-libs-8.1.21 (/usr/lib64/libpq.so.4) to postgresql84-libs-8.4.4 (/usr/lib64/libpq.so.5.2). Background on this request: Apache httpd's php's php-pgsql uses PostgreSQL 8.1 library (/usr/lib64/libpq.so.4), which leaks memory. PostgreSQL 8.4 library does not leak. Apache HTTP Server: httpd-2.2.3-43.el5.centos.3 mod_php: php-5.1.6-27.el5 PHP PostgreSQL interface is provided by: php-pgsql-5.1.6-27.el5, which uses postgresql-libs-8.1.21-1.el5_5.1 which provides /usr/lib64/libpq.so.4 which we've observed has a memory leak (and this memory leak is NOT present in libpq.so.5.2) I am trying to figure out how to get our httpd/mod_php/php-pgsql to use libpq.so.5.2 instead of libpq.so.4, and I thought I'd start by asking the php-pgsql maintainer, so this problem is fixed for everybody, not just for me. Please let me know if I can help in any way. Kind regards, Aleksey

dhcpd rpm
by m.roth＠5-cent.us 19 Oct '10

19 Oct '10

Folks, We've been having occasional issues with failover dhcpd. I went looking for "peer holds all free leases", and happened to run across <https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=610219>, which is rated important, and is supposed to be fixed in 3.0.5-24. Looking at the repo at kernel.org, all I see is what we have, dhclient-3.0.5-23.el5.x86_64.rpm. Any idea when this update will be released? mark "we won't mention 3.1 or 4.x"
