CentOS 5.9 i386 and x86_64 Packages Available in the Continuous Release (CR) Repository (Johnny Hughes) ---------------------------------------------------------------------- Message: 1 Date: Fri, 11 Jan 2013 07:46:19 -0600 From: Johnny Hughes <johnny(a)centos.org> Subject: [CentOS-announce] CentOS 5.9 i386 and x86_64 Packages Available in the Continuous Release (CR) Repository To: CentOS-Announce <centos-announce(a)centos.org> Message-ID: <50F017AB.10406(a)centos.org> Content-Type: text/plain; charset="iso-8859-1" The CentOS-5.9 Packages for the i386 and x86_64 Architectures are now available via the Continuous Release (CR) Repository. The CR Announcements for CentOS-5.9 can be viewed here: http://lists.centos.org/pipermail/centos-cr-announce/2013-January/thread.ht… More information about the CR Repository and how to install it is available here: http://wiki.centos.org/AdditionalResources/Repositories/CR As explained in the above link, we are still doing advanced QA testing on CentOS-5.9 and there may be some minor changes before the final release. This "opt-in" CR Repo process allows earlier access to our best effort packages now while we complete the final CentOS-5.9 QA processes, spin the ISOs and create an installable tree.

Re: [CentOS] Building Dovecot CentOS 5 RPMs with custom LDAP packages

However, IMHO building dovecot using standard openldap-devel on CentOS 5 means that, even though the final RPM works, it will use *ancient* openldap v2.3 libraries. If we manage to use custom openldap libaries (like those from LTB Openldap builds) then Dovecot can be built against modern/current Openldap v2.4 libraries. That may provide significant improvements to the final RPM, in terms of LDAP usage. In any case, I found the solution (based on the documentation: http://wiki2.dovecot.org/CompilingSource) I added the following lines (marked below with ++) in your spec file: %build export PATH=/usr/kerberos/bin:$PATH #required for fdpass.c line 125,190: dereferencing type-punned pointer will break strict-aliasing rules ++ export CPPFLAGS="${CPPFLAGS} -I/usr/local/openldap/include" ++ export LDFLAGS="${LDFLAGS} -L/usr/local/openldap/lib64" export CFLAGS="$RPM_OPT_FLAGS -fno-strict-aliasing" %configure INSTALL_DATA="install -c -p -m644" \ --docdir=%{_docdir}/%{name}-%{version} \ --disable-static \ --disable-rpath \ --with-nss \ --with-shadow \ --with-pam \ --with-gssapi=plugin \ --with-ldap=plugin \ ... So, this produces a dovecot package based on Openldap 2.4 libraries(follows excerpt from the rpmbuild output): ... Requires(interp): /bin/sh /bin/sh /bin/sh /bin/sh Requires(rpmlib): rpmlib(CompressedFileNames) <= 3.0.4-1 rpmlib(PayloadFilesHavePrefix) <= 4.0-1 Requires(pre): /bin/sh shadow-utils Requires(post): /bin/sh chkconfig shadow-utils Requires(preun): /bin/sh chkconfig initscripts shadow-utils Requires(postun): /bin/sh initscripts Requires: /bin/bash /bin/sh config(dovecot) = 1:2.1.13-3.centme initscripts ... libldap-2.4.so.2()(64bit) ... ... It was initially using: libldap-2.3.so.0()(64bit) Regards, Nick

I could go into recovery mode and get the installed system to come up that way, utilities like grub-install seemed to hang in attempting to write to the devices. I ended up just bailing, took a USB key installed it (it showed up as /dev/sda) and installed grub to the MBR there so now I can boot.

grub issues on reinstall.
by zGreenfelder 12 Jan '13

12 Jan '13

Hi all. sorry for an immediate question after subscribing, but I've managed to back myself into a frustrating corner. I've done some googling and come up dry, I figured I should try to post to the list while I dig through the archives. I have an issue with grub on a centos reinstall. my system previously had 1x 120g ide drive, 3 1tb sata drives in raid 5 md, 2 300 g in a raid 1 md,the /boot partition was on the ide drive, os on the raid 1 in a volume group and everything seemed fine. I downloaded the x86_86 iso a few days back and decided to just to a complete reinstall rather than burn myself with some odd upgrade path trying to put newer, larger drives into a md with a much smaller drive. I've since purchased some new drives and changed to 1 120 ide, 4 1 tb sata, 2 3tb sata. I've tried a few different combinations of install locations (e.g reused the ide as /boot, a 512 mb slice from a 1tb drive for /boot) but every layout I try seems to end up with a grub config that can not find the OS (if memory serves, the message comes back as error 15: file not found, hit return to reboot) the thing that seems odd to me is when I do the reinstall, the hdds seem to start much higher than I'd expect. there's no /dev/sda, b, c, d, ... I think they start at i. does anyone have some suggestions for what to try for this issue? Thanks. -- Even the Magic 8 ball has an opinion on email clients: Outlook not so good.

Building Dovecot CentOS 5 RPMs with custom LDAP packages
by Nikolaos Milas 11 Jan '13

11 Jan '13

Hi, We are (still) mainly using CentOS 5 (5.8 x86_64). As CentOS / EL 5 standard OpenLDAP packages are rather old (2.3.x), we've been using LTB OpenLDAP packages ( http://ltb-project.org/wiki/download#openldap) which get installed in non-standard file system locations. I am not much experienced in building RPMs and preparing spec files. We are currently using dovecot RPM packages from the atrpms repo (http://packages.atrpms.net/dist/el5/dovecot/) I would like to re-build Dovecot packages based on the LTB OpenLDAP RPM packages (OpenLDAP v2.4.x), esp. because I see that ATRPMs Dovecot RPM packages are built using OpenLDAP v2.3 devel code (i.e. standard CentOS OpenLDAP devel packages). In http://dl.atrpms.net/all/dovecot.spec I see: ------------------------------------------------ BuildRequires: openldap-devel, cyrus-sasl-devel ... Obsoletes: %{name}-pgsql < %{epoch}:%{version}-%{release}, %{name}-mysql < %{epoch}:%{version}-%{release}, %{name}-sqlite < %{epoch}:%{version}-%{release}, %{name}-ldap < %{epoch}:%{version}-%{release}, $ Conflicts: %{name}-pgsql > %{epoch}:%{version}-%{release}, %{name}-mysql > %{epoch}:%{version}-%{release}, %{name}-sqlite > %{epoch}:%{version}-%{release}, %{name}-ldap > %{epoch}:%{version}-%{release}, $ ------------------------------------------------ So, I guess I can/should change the former line to: BuildRequires: openldap-ltb-debuginfo, cyrus-sasl-devel Note: The final Dovecot RPM and the associated executables (included therein) do not need any LDAP dynamic library in order to run with LDAP support; i.e. after building, the produced package does not require any ldap package on the system. Question 1: What other changes/additions should we make in the spec file in order to specify that we will be using (if needed) LDAP libraries from: /usr/local/openldap/lib64 and include files from: /usr/local/openldap/include (rather than from /usr/lib64 and /usr/include, respectively, which are the standard file paths used in native openldap-devel RPM)? Question 2: How the Obsoletes and Conflicts lines should be changed? Any other associated info would be appreciated. Thanks, Nick

GnuTLS v3.1.6 on CentOS 6.3
by Bry8 Star 11 Jan '13

11 Jan '13

Hi, on CentOS 6.3 (32-bit) current & default GnuTLS is version 2.8.5-4.el6_2.2 gnutls.i686 ( where can i get a src rpm for at-least trying it from a 2nd/different directory ? ) Can someone kindly point to an article that will help to effectively upgrade to GnuTLS v3.1.1 or later+stable version, on CentOS 6.3 (32-bit) ? Need the DANE supported GnuTLS, will be used for various GnuTLS depended apps. Thanks in advance, -- Bright Star.

IE 9 not sending digest auth info
by Paul Heinlein 11 Jan '13

11 Jan '13

I migrated our internal wiki server last week, and some IE users aren't able to authenticate. The service is hosted by Apache using Digest authentication. It migrated from Apache 2.2.9 (Debian 5) to Apache 2.2.15 (CentOS 6). The internal hostname for the wiki server is a DNS CNAME that was repointed from one host to another during the cutover. In a normal session, 1. Client sends GET 2. Server sends 401 with WWW-Authenticate header 3. Client sends GET with Authorization header 4. Server sends 200 with Authentication-Info header and page content When using IE 9 (and possibly 8, I'm still trying to track that down), 1. Client sends GET 2. Server sends 401 with WWW-Authenticate header 3. Client resends GET (*without* Authorization header) 4. Server sends 401 with WWW-Authenticate header 5. Etc. IE seems to be ignoring 401 and/or the WWW-Authenticate headers. Using Chrome on Windows works fine; the issues are specific to IE. Any ideas? My google-fu has failed me. -- Paul Heinlein <> heinlein(a)madboa.com <> http://www.madboa.com/
