Thanks for the reply. I've recently started working for a large hosting company, so there's a reasonable amount of scope for anything that can go wrong going wrong at some point, so I wanted to be prepared in advance for as many eventualities as possible :) *sigh* Good luck with the new job. I've seen root partitions fill up a few times, but in my own experience we've always been able to get in and clear out some space before it's knocked the server over. I'll look into it a bit further tho. One trick my manager's shown me, that you can use to keep things going while dealing with a root filesystem full is to use tune2fs to lower the f/s reserved space. mark ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Problems with Adobe flash-plugin and Firefox-3.5.x under CentOs-5.3 (yum up to date)
Hi, I am running 32-bit Firefox-3.5.3 on Centos-5.3 (64-bit kernel) on a Dell Precision M65 laptop. This is likely a Adobe problem, but maybe someone else has seen this before. Please CC me, as I only receive the digest version of the list. When using the 10.0.32.18-release version of the flash-plugin, trying to access *any* page containing flash (e.g. www.adobe.com) causes the browser to die. This also happens with version 10.0.22.87. Version 9.0.115.0 works fine. To avoid problems with add-ons, Firefox is started with -safe-mode. As far as I know, the problem also happens with Firefox-3.0.x. snip I filed a bug with the firefox team about exactly that. I'm running 64 bit CentOS 5.3, with updates, and it happens with both firefox 3.5.3 and 3.0.14.

Do i make changes to /usr/share/logwatch/default.conf/* files or copy them to their equivalent name place in /etc/logwatch and edit making changes to those? Thanks much. I actually don't know. They run logwatch here, and I just look at the emails. Every hour. Every day.

It has to be stored somewhere on this one server. Can you suggest any reason that you think it's not? *IF* I understand this correctly, the simple greeter shows up when you wake up the screensaver, and displays the names of those recently logged in, and it *seems* as though it can also display pictures. Given the location and filename, I was assuming that it gets them that way. which would imply that it might work *if* the home directory was always mounted, not automounted on logon.

So I tried live CDs of ubuntu and SuSE. ubuntu couldn't figure out what to do with my wireless card, while SuSE thought about it for 30 sec, and a window popped up, telling me I had a new wireless card, and would I like to configure it. I eventually upgraded to opensuse 10.3 Just in the month, I went up to CentOS 5.3. Now, there was one major problem: it could figure wirelesss, but unlike my year+ old opensuse, it didn't know WPA, and I went through days of grief until I got that going... so beware of that (and I'm *very* unhappy that it is such a song and dance to get that working... but I don't have time, with a new job, to spend time writing something that will do it all). The other thing is that ubuntu does some things I consider odd, and puts some things in odd places (say, not having your web stuff under /var/www, etc). So, pick your poison. g mark ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] samba file locking

After that it snip I believe the problem is that you are rewriting the file on the server (with scp) while it is open on the clients (using NFS? or mounted CIFS?). As the clients have the file open they will have parts of it cached, and those parts will be updated on the server but the cache will persist on the client for sometimes quite a long time, or until you unmount the network filesystem, which it seems is what you are currently doing to fix the issue.

Re: [CentOS] CentOS for non-tech user
m.r...@5-cent.us a écrit : I also have CentOS at home. There are quirks, though: for example, I tried to run kaffeine last night, and it couldn't find libkaffeinepart.so. I tried adding /opt/kde3/lib to LD_LIBRARY_PATH, to LOAD_LIBwhatever, and even did an ldconfig, and it *still* can't find it (I run icewm, btw, not KDE). Kaffeine is basically Xine for KDE. Since you're running IceWM, you might as well give Xine or Gxine (no Gnome deps) a spin. I might... but I *really* want to know *why* it can't find the library, that's right there. That's problems waiting to happen. mark ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] selinux...
Have I mentioned that I am less than enthralled with selinux? My latest issue is continuing messages in the /var/log/messages, which complain, for example, that siteminder can't write to smagent log (well, it can, since we've got selinux in permissive mode, and no, we have no control over using either siteminder or selinux). I've done what it says will solve the problem. A number of times. Discussing it with my manager, it seems as though selinux DOES NOT HAVE CORRECT ERROR HANDLING, and is falling through to a default error, and is *not* telling me the true cause. Anyone else seen this? Clues for the poor? (And please, if you're going to say anything about getting rid of either, just don't: as I said, we have *zero* control over what the security people, or upper management, demand.) mark ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
