manager sudo file
by Jamie Bohr 16 Mar '10

16 Mar '10

I recently because the Senior Server Architect (Server Administrator) and now support over 1500 servers and workstations and am looking for an easier way to mange privileged access. I have a mix of RHEL, HP-UX and Solaris based devices. We use CFenigine to manage part of configuration. The devices are located at 40 different sites. basic requirements: 1. Access is manage from a central location, possible CFengine manged 2. Sudoer file is updated at least once a day, again possible CFegine managed 3. Sudoer file would need to be built custom for each device, a complex sudoer file is not easy to manage. 4. Compare the existing sudo file to the proposed one to see if unauthorized changes were made. I realize this would be had to do especially if there are authorized changes in the new file. 5. All commands are logged. advanced requirements, things that would be nice to have 1. Once privileged access is granted user gets access w/o having to update the client 2. If privileged access is revoked users will no longer have privileged access w/o having to update the client 3. A reason for being root is asked of the user before granting "su -" access but is not logged if they user just runs a command. 4. Limit changing root's password, even for root. A tool like Power Broker would be great but I have don't have the budget for it. I looked at Free IPA but it looks complex and requires a greater commitment then just privileged access control. Googling did not provide a possible solution but I am hoping the experts on the list will point me in the right direction or give some advice. -- Jamie Bohr

Backup, what system files are *really* important?
by Stuart McGraw 16 Mar '10

16 Mar '10

I currently backup user only my user files with the understanding that if I lose important system files, I will reinstall the system from distribution media. Yesterday I had a little accident when I accidentally deleted an unknown number of files in /var. But since the rpm database was still intact, I was able to "rpm --verify" all my packages, identify those with missing /var files and reinstall just those rpms. Which leads to my question... Are there certain files and directories that should be saved because they are unusually important and can help recover from common problems, without backing up *all* the system files? In my case above, having the rpm database was critical. I backup config files in /etc and elsewhere that I've modified. Are there other *really* important system files I should be saving?

lzma compression on official isos vs Deltaisos
by Antonio Olivares 15 Mar '10

15 Mar '10

Dear fellow users, I want to pose a quick questions. I know Mr. A Robatino posts deltaisos regularly which amounts to a certain amount of savings when one downloads a deltaiso. Although I have never downloaded one, I ask if one can save more bandwidth if we use lzma compression. I ask this question because TeXLive2009 comes in a iso.xz format which is lzma compression and saves some bandwidth. Would Fedora welcome such savings and distributing isos, whether test or official releases as lzma compressed? Has this been thought of before? Thank you in advance for commenting/answering this question. Regards, Antonio

lzma compression on official isos vs Deltaisos
by Andre Robatino 15 Mar '10

15 Mar '10

Starting with Fedora 12, RPM packages are compressed using XZ instead of gzip. As a result, the F12 ISOs are smaller: F11 DVD sizes (bytes): i386: 3683829760 ppc: 4606894080 x86_64: 4268124160 F12 DVD sizes (bytes): i386: 3204427776 ppc: 3738935296 x86_64: 3537600512 See http://fedoraproject.org/wiki/Features/XZRpmPayloads

guest tech documentation
by Bill Davidsen 15 Mar '10

15 Mar '10

I am looking for a doc to use with a discussion of guest OS on Linux. I can get through xen and kvm pretty well, but user mode Linux and lguest, not so much. And because this will be a nuts and bolts discussion, while I will mention libvirt, running from cli is the preferred presentation. Someone else will be talking about vmware, virtualbox, etc, etc. I'm looking for *simple* examples of starting a machine and how one is different from the other. And I would rather believe that someone else has done this and I just haven't found it, rather than putting it off at least a month while I learn more than I ever wanted to know about all of these, so I can build my own presentation. -- Bill Davidsen <davidsen(a)tmr.com> "We have more to fear from the bungling of the incompetent than from the machinations of the wicked." - from Slashdot

Best means of upgrade
by Bill Davidsen 15 Mar '10

15 Mar '10

I have a server running a 32 bit release and some critical VMs, so I really don't want to mess it up. It also has an old 64 bit (FC6) release which I get to via chain loader from the grub in 32 bit. I want to upgrade the 64 bit (which I don't use) to the FC13 pre stuff from a daily spin. The config is thus, 32 bit boot is in a raid-1 array, as is the 64 bit boot. Those are based on primary partitions. Then there is a raid-6 array with LVM on it, providing /home, and Root32 and Root64 LVs. I want to put the latest 64 bit on the array for /boor64 and the LV for /Root64. I do *NOT* want to hose the 32 bit or MBR! My choices are: 1 - try to do an upgrade from FC6 to FC13 over the 64 bit install 2 - do a fresh fc13 install, also over the 64 bit old stuff 3 - do it on another machine, too likely to hose the production stuff (do it on the fc10 bits of a laptop which is not critical) Any relevant thoughts on doing the install so I can be sure I can continue to use the chain loader from the 32 bit production stuff? -- Bill Davidsen <davidsen(a)tmr.com> "We have more to fear from the bungling of the incompetent than from the machinations of the wicked." - from Slashdot

very odd screen goes dim bug in f12
by Genes MailLists 15 Mar '10

15 Mar '10

I just installed a fresh f12 - fully updated - lenovo T61p laptop - using nouveau. If i go to a virtual terminal - or if I set the run level to 3 (no graphics). After some period the screen goes dark - fine - however when I awaken the screen the backlight on the LCD display is almost off - starting up (or switching back to vt1) - the graphics are dimmed too. Rebooting does NOT restore the backlight - it remains dim. If I now login - I have power applet on taskbar - suddenly (perhaps when power applet starts) suddenly screen goes bright again!!! Something about text vt's .. and dpms truly mucks up the backlight. Anyone else seen this weird/nasty[1] bug? gene [1] - I thought my display had died ... and that would be bad since this is used for RW (real work)!!!
