How To Send Files Securely From Fedora
by Robert L Cochran 04 May '09

04 May '09

I want to send files securely from my Fedora 11 (Preview) or Fedora 10 systems to a Microsoft Windows (Home Edition) user who quickly gets lost if asked to do anything complex. By "securely" sending files, I mean I wish to attach files to an email and then send them over the wire either encrypted or password protected such that there is little possibility of anyone but the intended recipient being able to see the files in clear. I would also like the user to be able to send files back to me which are similarly secured. The user likes Windows Live Mail. I do not think the user capable of managing public keys or of understanding how to decrypt public-key based files unless it can be done with one or two mouse clicks. I could do the initial setup and testing myself. Everything has to be geared to allowing a quite basic user to view the cleartext quickly and very simply, without others on the Internet being able to crack it. I've thought of sending password-protected zip files using the Fedora zip utility. Perhaps these are compatible with the same utility in Windows XP? Any suggestions? Bob

Re: nVidia vs. ATI graphics card for fedora
by Jack Howarth 04 May '09

04 May '09

I haven't seen this issue mentioned yet, but ATI has just depreciated all hardware older than the HD series of cards as of the 9.3 release... http://support.amd.com/us/gpudownload/linux/legacy/Pages/radeon_linux.aspx?… This means 9.4 and beyond will no longer promise support for these cards (although it may still work for a short while). I should have saw this coming when I couldn't get 9.2 or 9.3 to produce video on my X1650 under x86_64 Fedora 10. We are all stuck with the free drivers now. Jack

Kevin, Our experience here with x86_64 Fedora 10 linux and the radeon drivers on a couple machines with Radeon X1650 Pro cards has been very uneven. One of the boxes is very fragile to spontaneous reboots when running the free drivers and using UCSF Chimera to work with MD trajectories. The other box still has a habit of blanking the screen for minutes at time despite having the nomodeset flag passed to the kernel. I am afraid things will only get worse under Fedora 11. So far, testing on a MacBook Pro with X1600 graphics, I find that pymol still renders outside of its windows. While I appreciate the aims of these changes to X11 and the free drivers, the problem is that Fedora has become destablized. It is really exposing the limitations of a monolithic kernel when the graphics drivers keep taking down the entire box. Jack ps We run a large amount of OpenGL software (free and commercial) and have found the non-free drivers to be more compatible in general. Hopefully this will improve over time.

Have you tried using a boot.iso image to do a network install? There were a lot of bugs addressed in anaconda-11.5.0.48-1 (-2 is now available) since the preview image.

Could some kind soul make an rpm and put it into a repository for gnome-format? It's at http://live.gnome.org/gnome-format -- and there are .debs there, but no .rpms. It *might* (I'm told) be able to handle the trouble some of us have been having wiping Conficker-prone M$-foulness (automount, I think) off thumb drives. -- Beartooth Staffwright, PhD, Neo-Redneck Linux Convert Remember I know precious little of what I am talking about.

internal system error
by potat0 04 May '09

04 May '09

Lately I've been getting very frequently (let's say every quarter of an hour) a warning about an internal system error, specifically a Package Manager error. In detail: Error Type: Error Value: 'NoneType' object is unsubscriptable File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 2316, in main() File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 2313, in main backend.dispatcher(sys.argv[1:]) File : /usr/lib/python2.5/site-packages/packagekit/backend.py, line 600, in dispatcher self.dispatch_command(args[0], args[1:]) File : /usr/lib/python2.5/site-packages/packagekit/backend.py, line 508, in dispatch_command self.get_updates(filters) File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 1769, in get_updates self._check_init() File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 1996, in _check_init self.yumbase.repos.doSetup() File : /usr/lib/python2.5/site-packages/yum/repos.py, line 71, in doSetup self.ayum.plugins.run('postreposetup') File : /usr/lib/python2.5/site-packages/yum/plugins.py, line 178, in run func(conduitcls(self, self.base, conf, **kwargs)) File : /usr/lib/yum-plugins/rpm-warm-cache.py, line 32, in postreposetup_hook cmd = commands[0] Does anybody know what I should do to fix it?

Installation of F 11
by mike 04 May '09

04 May '09

Tried to install F 11 on a dual boot machine. Base is XP and the second is currently F 10. The install failed with an error message that the partition could not be installed. Then the machine would not reboot be died at a grub shell. I pulled out my F 10 DVD and reinstalled a base F 10 over the existing Linux partition. This gave me back grub in a dual boot and a fresh F 10 not updated. Y'all can keep F 11. Let me know when it maybe works!

Selinux disallows read-only loop mount of a file, but only at boot
by David 04 May '09

04 May '09

I'm exploring new territory: the first time I've ever tried to mount a loop device (a ro file) at boot using fstab. My fstab entry works fine from the command line, but it fails at boot time due to a selinux avc error, I dont understand why but I suspect it is because the file context is unsuitable. The file and context are: [david@kablamm ~]$ ls -lZ /HUGE/get/iso/Fedora-09-i386-DVD/Fedora-09-i386-DVD.iso -r--r----- root share unconfined_u:object_r:default_t:s0 /HUGE/get/iso/Fedora-09-i386-DVD/Fedora-09-i386-DVD.iso The fstab line is: /HUGE/get/iso/Fedora-09-i386-DVD/Fedora-09-i386-DVD.iso /mnt/Fedora-09-i386-DVD iso9660 loop,ro,gid=share 0 0 The command line that works is: # mount /mnt/Fedora-09-i386-DVD The boot-time error messages are: Mounting local filesystems: /HUGE/get/iso/Fedora-09-i386-DVD/Fedora-09-i386-DVD.iso: Permission denied [FAILED] Mounting other filesystems: /HUGE/get/iso/Fedora-09-i386-DVD/Fedora-09-i386-DVD.iso: Permission denied [FAILED] and from dmesg: type=1400 audit(1241411595.523:4): avc: denied { read } for pid=1335 comm="mount" name="Fedora-09-i386-DVD.iso" dev=sdb2 ino=1922 scontext=system_u:system_r:mount_t:s0 tcontext=unconfined_u:object_r:default_t:s0 tclass=file and my selinux status is: [root@kablamm ~]# sestatus SELinux status: enabled SELinuxfs mount: /selinux Current mode: enforcing Mode from config file: enforcing Policy version: 22 Policy from config file: targeted QUESTIONS: I'm guessing that the problem is the file's tcontext .. what should it be? Is it just a matter of changing it to mount_t, the same as the error message scontext? The command # sesearch --allow -s mount_t -c file -p read gives 1292 results. How could I decide which one of these to use? And if anyone can say why it does not matter after boot time, I'd appreciate understanding that. Possibly something to do with context transitions? I've not attempted any trial and error solution, prefer to comprehend security tools if possible. Thanks.
