Re: [CentOS] Forward all traffic from public IP A to public IP B?

Feedback appreciated, What I've always wanted is a tool that would manage a group of machine configurations as branches in subversion so the tool itself wouldn't need any diffing capability and could be wrapped by viewvc for web browsing, mesh nicely with router and other text base config management, etc. By 'configurations', on RPM based machines, I'd want the package list exported in a form that yum or kickstart could use to re-create the set (and I suppose to get this right you also have to build a local repository containing all of them because rpm/yum are too dumb to know where they came from, given multiple repositories), and copies of all the files in /etc/ and other optional places that are not exactly as installed from an RPM. Is such a thing feasible, and if you can get that far, can it become a 'configuration factory' where you'd copy the starting config close to what you want to a new branch, edit a few files for the needed changes to produce a new machine, commit them, and then have a tool build that machine or a disk image of it? What I'm after is something that will let me make on-the-fly changes to any running machine, but pull those changes back to a central management tool in a way that makes it easy to see differences across time or between similar machines, and to use the current setup of any machine as the starting point for a new one. Most of the tools I've seen so far involve their own abstractions to describe configurations and require them to be made at the central management tool. That's not what I want. I want to do configurations using the native setup on one or more machines whether or not the management tool has an abstraction for it and have a way to use that going forward and to track differences without any intermediate abstractions. I suppose in a way the version control's branch/rev/tag mechanism becomes an abstraction for the whole machine state at a point in time. -- Les Mikesell [EMAIL PROTECTED] ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] kbs-CentOS-Testing gnucash: status for CentOS 5?
I decided I would like to try GnuCash on my 5.x desktop system. I did an available list and got this gnucash.i3862.2.4-1.el5.kb kbs-CentOS-Testi gnucash-docs.noarch 2.2.0-2.el5.kb kbs-CentOS-Testi Did a yum --enablerepo=kbs-CentOS-Testing install gnucash\* That produced Package gnucash-docs-2.2.0-2.el5.kb.noarch.rpm is not signed I figured I had forgot to install the gpg key, so I did that. Well, now I have to instances of that key. When I try to remove one copy, # rpm -e gpg-pubkey-3e13cf5b-422eea1c error: gpg-pubkey-3e13cf5b-422eea1c specifies multiple packages I tried removing the /var/lib/rpm/__* and rebuild, but no help. Still have two instances of the key. Any way to clean that without a remove and reinstall of all the keys? Anyway, a search of the archives has an entry indicating that gnucash was available for CentOS 4.x, but nada about 5. Am I too early on this? Anyhoo, figuring that docs could be addressed later, I then foolishly (need more coffee?) did yum --enablerepo=kbs-CentOS-Testing install --exclude=gnucash-docs \ gnucash which, of course produced Error: Missing Dependency: gnucash-docs = 2.2.0 is needed by package gnucash-2.2.4-1.el5.kb.i386 (kbs-CentOS-Testing) Undaunted, I figured to download via yum and force installation with nodeps (hmm, yum --downloadonly didn't work. Nothing in the docs about that though. Did yumdownloader --enablerepo=kbs-CentOS-Testing gnucash-docs and that worked) Then rpm --install --nodeps gnucash-docs-2.2.0-2.el5.kb.noarch.rpm worked, but gave I/O error : Attempt to load network entity http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd I/O error : Attempt to load network entity http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd I/O error : Attempt to load network entity http://www.oasis-open.org/docbook/xml/4.4/docbookx.dtd The docs were installed though AFAICT. ISTR seeing stuff similar to this with other packages in the dim past. Don't recall any solutions though. I wonder if there's a way to suppress that activity. I don't particularly care for packages that require on-line references for local and potentially sensitive work. I'm thinking there might be a configuration file I could modify because I see some similar files already on the system. I'll pursue that later if I get gnucash installed. Back to the primary task, did yum --enablerepo=kbs-CentOS-Testing install gnucash That produced Package gwenhywfar-2.6.2-2.el5.kb.i386.rpm is not signed At that point I felt maybe I was a bit premature as I had already confirmed that I had the gpg key installed. Any words of wisdom for me? If I don't need to worry about the signing issues, I guess I could download and install all with --nodeps. Good/bad idea? Anything I might do to help the process along? I've not done any rpm work, so it might take awhile if there is anything too technical. I'm going to fire up my 4.x and see if it works there. I can muddle through there, with a small amount of inconvenience. But that might be worth it. Before I forget, thanks to you and all the crew for the hard work that benefits us all.
