[CentOS] Can I force yum to only use http.
Our outsourced IT department has decided to use white listing on the firewalls for outbound ftp. I was given a list of sites our lab had accessed via ftp and eventually tracked them down to Linux machines running yum. They are all CentOS 5 or 6 with a smattering of 7. It is impractical to list all the possibilities since they change on a regular basis. Also any 3rd party repos we need are another ball of wax. Various Google searches and the manual page have not shown me how to avoid using ftp mirrors. I have considered taking out the ftp-proxy information so that the ftp cannot get out, but I suspect it will just hang waiting for a response. Does anyone have any suggestions on ways to tell yum not to use ftp as the download mechanism? Thank you in advance.

I had assumed that the code underlying yum had its own stack for dealing with ftp://... urls. I will try this on a couple of machines.

[CentOS] Unresolved references in libnetsnmpagent.so
Hi, I am running an up to date centos5.9 system. The package, net-snmp-devel-5.3.2.2-20.el5 Contains among oteher things: /usr/lib/libnetsnmpagent.so When I link with this library (-lnetsnmpagent), I get a bunch of unresolved references.: My Google searches has not given me hints to where the C to Perl library exists. I would guess that yum would have loaded the correct package as a dependency: Could someone point me to the correct library?

Re: [CentOS] Strange Samba Issue
Another possibility is selinux. I just build a CentOS 6 machine. When I tried mapping a drive, I kept getting permission denied. When I got into the /tmp directory, I was able to create files from Windows via Samba and see those files but ones created on the folder either did not show up or were inaccessible. Listing the extended attributes showed that the selinux part of the attributes was different. Researching showed that there are a number of little selinux flags to set to get samba to work. I went into /etc/selinux/config and turned off selinux to test and rebooted. The problems went away. Now I just have to figure out what to configure, so I can turn selinux back on.

[CentOS] Dug myself into a hole
I just build a CentOS 6 machine to replace my old machine which broke to where I could not fix it. In attempting to get the applications running which had worked on the old machine, I did updates from several repos such as rpmforge, atrpms, livna, epel, etc. Some of the attempts ended going down blind alleys. Now I have a mix of rpm's from various sites that I do not need, but they are listed as dependencies of other rpm's. The rpmforge rpm's are marked with "rf". Is there a process to check which of these rpm's are also in the base libraries and force them back in? I really do not want to go back to square 1 and reload the system from scratch.

The "yum distro-sync' works well. I discovered the priorities plug-in in the CentOS wiki. (wiki.centos.org/PackageManagement/Yum/Priorities) You can make sure a third party rpm never replaces a base rpm. Of course if not replacing the base rpm means the application does not work... Well you have to decide what you want to do. Bob S ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] Upgrading to CentOS 6
I recently built a CentOS 6 system as my main machine at home. With a bit of help from members of this list, it is now working better than the machine it replaced (RIP). The new machine works so well, that I would like to convert some CentOS 5 machines to CentOS6. I did some research on the web and the new install is still considered the proper way to upgrade CentOS. Same as Fedora and RHEL. The question becomes, "What makes the Ubuntu developers so clever that they can do major upgrades through their apt based update system?" There must be some sort of gotcha or tradeoff involved in allowing this. Does anyone have any insights on why they can get away with this while CentOS cannot? ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

You answered my questions clearly and concisely. My replacement of the machine at home went from Fedora Core 6 to CentOS 6. Both 6's right :-). The old box had the power supply smoke (literally) and took out something on the main board so it would no longer see disks. The boot disk failed as well. I kept Firefox and Thunderbird up to date manually with packages downloaded from the Mozilla site. Right at the end, I got to where they would not load because of shared object incompatibilities. Why would someone wait that long to upgrade? The machine at home is very different than the machines at work. At work, new project, new machine, new OS install. Get the latest version of RHEL and that is where that project stays. At home there is a lot more customization. I transferred my CD's to MP3 format and now buy MP3's from Amazon. As you know, I need a third party repo to get MP3 decoders. My machine now ties into my stereo and that is how I listen to music. Same sort of stuff goes for playing movies. Lots of other customizations as well. Projects come and projects go. I could not get xmms (with mp3) running on my CentOS machine. Eventually found "Audacious" which fills in nicely. And on and on. The priorities yum plug-in does a real nice job of protecting my machine from being mutilated by third party repositories. Cudo's to those guys. Bottom line, rebuilding a home machine is a lot more trouble than setting up a new machine at work. Thanks again for the insights into the upgrade process.

Setting up IPtables is more complicated which can be read as "easier to get it wrong". The question become, "Why get rid of it?" It is small works well and works the same across many flavors of UNIX. I have not looked recently, but I would guess that the source code does not change very often. Just my 2cents.

[CentOS] Why are hplip and hpijs always so back dated?
My fully patched CentOS 6.5 system uses: hplip-common-3.12.4-4.el6_4.1.i686 hpijs-3.12.4-4.el6_4.1.i686 hplip-libs-3.12.4-4.el6_4.1.i686 My wife's printer becomes supported at 3.13.somethingOrOther and the current release is 3.14.something. Why are we so far behind? I realize that I can download the latest, uninstall the RPM versions and compile and build and install the source copy. If I was going to follow that route, I would prefer to build an rpm and install it normally. I have been looking on the Internet and not found anything to turn the release from HP into a binary RPM. (That does not mean it is not there.) I know it must be doable since there are rpm's in the repositories. My skill with RPM's is somewhat limited, but does anyone know of a set of instructions and a spec file that could be used to get started on this process?
