Had I known of it before we started down this road then we might have used it instead. However, at the moment we seem to have a working solution and so we will stick with that for now. I am not sure what effect disabling SELinux support in SSH actually has from a security standpoint. So, if anyone cares to enlighten me on the the consequences I would like to know.

Yum: strange dependencies
by Fajar Priyanto 04 Feb '10

04 Feb '10

Hi all, On Centos 5.4 minimum installation, I tried to install these packages (notice the dependencies): =================================================================================================================== Package Arch Version Repository Size =================================================================================================================== Installing: mc i386 1:4.6.1a-35.el5 base 2.1 M mdadm i386 2.6.9-2.el5 base 827 k ntp i386 4.2.2p1-9.el5.centos.2.1 updates 1.3 M sudo i386 1.6.9p17-5.el5 base 218 k Installing for dependencies: exim i386 4.63-3.el5 base 1.2 M mysql i386 5.0.77-4.el5_4.1 updates 4.8 M perl i386 4:5.8.8-27.el5 base 12 M perl-DBI i386 1.52-2.el5 base 600 k postgresql-libs i386 8.1.18-2.el5_4.1 updates 196 k Transaction Summary =================================================================================================================== Install 9 Package(s) Update 0 Package(s) Remove 0 Package(s) Total download size: 23 M I didn't want all those dependencies, especially exim and mysql. So, instead of installing mc, mdadm, ntp, and sudo at the same time, I installed them one by one and this time no exim and mysql (mc still wanted perl, fine) dependencies. Any thought why was that? Thank you.

Updating gfortran in CentOS 5.4?
by Jon Forrest 04 Feb '10

04 Feb '10

We're finding that several of the packages we need don't compile using the version 4.1.2 of gfortran that comes with CentOS 5.4. So, I've built the latest version of gfortran (e.g. 4.4.2) but I've done it so that all the new version's files go in /share/apps/gnu so that they don't interfere with the standard gcc distribution (building gfortran requires building some parts of gcc). Although I can compile and run a simple fortran "Hello, world" program using the version of gfortran I built this way, trying to run a more complex application, such as charmm (a molecular dynamics program), fails. When I run charmm, I get the message "Killed". Running strace ./charmm shows execve("./charmm", ["./charmm"], [/* 43 vars */] <unfinished ...> +++ killed by SIGKILL Since "Hello, world" compiles and runs, but charmm compiles and doesn't run, there's something wrong with how charmm is linked. Also, although the 'file charmm' command shows an ELF 64-bit dynamically linked file, 'ldd charmm' says " not a dynamic executable" (note no file name). So, something is strange. What have other people done about building new versions of gfortran on CentOS 5.4? Is this worth the trouble? Or, is it better to just go with Intel Fortran?

atime, relatime query
by Rajagopal Swaminathan 04 Feb '10

04 Feb '10

Greetings, I am aware that mounting filesystems with noatime option greatly increases speed. I have tried to follow discussion on the pros and cons of using noatime. I have however not been able to mount with the option relatime in centos 5.2. But in a production db server, which is backed up by HP DP, is it advisable to mount with noatime? Anybody care to share their experience on it? Regards Rajagopal

subversion 1.6.9 and sqlite 3.6.22
by Benjamin Franz 03 Feb '10

03 Feb '10

I'm in the process of setting up subversion and since the version packages with C5 is, shall we say, showing its age, I've built an updated version. In order to do that I had to upgrade sqlite from the default 3.3.6 (which the current subversion will not build with) and I went with 3.6.22. Has anyone else had any experience with whether or not that breaks anything? I'm a little nervous because sqlite is used all over the place (rpm, X11, apache, yum, selinux, system-config-*, various perl modules, gnome, gimp, php, and so on). -- Benjamin Franz

Good > luck. > Hi Brent, Thanks for taking the trouble to reply to me personally. I'm using CentOS 5.3 on my PC simply because that's the latest version which I had downloaded and burnt to CDs! I'm afraid I'm a bit slow in keeping up with the fast-moving development of CentOS and am always a bit reluctant to rebuild/reinstall the operating system on my PC. However, I thought that 5.3 was sufficiently up-to-date for my purposes, but was disappointed when I found that neither the wifi on my laptop nor skype on my PC worked properly! I'm now using Ubuntu 9.04 on my laptop which seems to work brilliantly and is very user-friendly. I'm thinking of using Ubuntu (server edition?) on my PC, after years of using RedHat and CentOS, because as a 'semi-tech' user (and great supporter of linux) I do like the user-friendliness of Ubuntu! Best regards, Andy
