Has anyone tried a dual boot of Win 8 and Fedora 17? Are there any special problems in doing this? -- ======================================================================= To err is human, to forgive unusual. ======================================================================= Aaron Konstam telephone: (210) 656-0355 e-mail: akonstam(a)sbcglobal.net

dynamic ip ok for NFS/LDAP servers? Network Gurus?
by Jack Craig 03 Dec '12

03 Dec '12

Hi Folks, The following strikes me as wrong, but i am Not guru, so i thought to ask this forum where the wizards Do Live! :) Pls consider a configuration with a single host providing NFS4 /home directories for other hosts in a 6 host cluster. Further, openldap is on the same host to provide for authentication on all 6. the architect says its ok to configure all hosts w/DHCP, but i see the ip changing every day or 2 (many reboots due setup). I am a huge fan of static ip for servers, but what do i know?! :( So, Question, is DHCP ok for the 6 hosts in this config, or go static. More, static on server only maybe? TIA, jackc...

not sure this is the best place, but...

guys, I rely on a python script that *I* did not write to make my keys click. {i've already run thru two expensive "clicky" keyboards... .} anyway, my click program no longer works. it cant find "Xlib" I have no clue. so I did a # yum install python* to see if that got the missing parts. it turns out that there is, indeed, something that is program in the install. the key-click.py script has been working on ubuntu and now on fedora-17. I'm wondering if this: --> Running transaction check ---> Package hunspell-en-GB.noarch 0:0.20110318-9.fc17 will be installed ---> Package python-tahrir.noarch 0:0.1.8-1.fc17 will be installed --> Processing Dependency: python-pyramid-tm for package: python-tahrir-0.1.8-1.fc17.noarch --> Finished Dependency Resolution Error: Package: python-tahrir-0.1.8-1.fc17.noarch (updates) Requires: python-pyramid-tm You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest might be the cause of my click error: pts/4 15:17 <tao> [3851] ./key_click.py ~/bin/keyclick/src/keyclick ** Message: pygobject_register_sinkfunc is deprecated (GstObject) Traceback (most recent call last): File "./key_click.py", line 37, in <module> import xlib File "/home/kline/bin/keyclick/src/keyclick/xlib.py", line 25, in <module> from Xlib import display ImportError: No module named Xlib Another thought is that under gnome, the click program worked. any ideas? gary PS: I Want to port this keyclick program to C because it is a load hog... . -- Gary Kline kline(a)thought.org http://www.thought.org Public Service Unix Twenty-six years of service to the Unix community.

Bash - an odd problem using sed or awk or for
by John Horne 02 Dec '12

02 Dec '12

Hello, I have a bash script in which a variable is set to one or more lines of text. What I want is to remove any lines up to and including a blank line (or alternatively to echo all the lines after the last blank line). There may be zero or more blank lines, and the blank lines need not be consecutive. If there is no blank line, then all the lines should be shown. If the last line is blank, then nothing should be shown. So for example the variable may contain: ============ (the '=' are not part of the variable) abc def hijk xyz ============ So in this case what is wanted is: ============ hijk xyz ============ to be shown. I tried something like: echo "$XX" | sed -e '/./,/^$/d' but this didn't display anything. (Where XX is the variable.) I also tried using a 'for' loop but again this displayed nothing: opt="" IFS=$'\n' for n in $XX; do test -z "$n" && opt="" || opt="$opt $n"; done (Echoing $opt after this shows that it contains nothing.) I'm not sure why but even using a for loop just to show it had seen a blank line didn't work either (using something like 'test -z "$n" && echo found'). My understanding was that by setting IFS to a newline, then the 'for' loop should see the blank line and just set '$n' to the null string. We should then be able to test on that. Ideally what I am looking for is a snappy one line 'sed' or 'awk' command to handle this :-) Unfortunately at the moment I seem to be getting nowhere though, even with the 'for' loop. Thanks, John. -- John Horne, Plymouth University, UK Tel: +44 (0)1752 587287 Fax: +44 (0)1752 587001

Preferred CPU model SandyBridge not allowed by hypervisor
by Corinna Vinschen 02 Dec '12

02 Dec '12

Hi, Friday I switched one of my machines from an Opteron 2382 based motherboard to a Xeon E5-2640 based one. I'm using this Fedora 17 machine to run my Windows test VMs using qemu-kvm. I changed the Processor configuration setting in virt-manager from Opteron G3 to SandyBridge and now, whenever I start a VM, I get the message from the subject line: Preferred CPU model SandyBridge not allowed by hypervisor; closest supported model will be used ps -ef | grep kvm shows the following CPU setting: /usr/bin/qemu-kvm [...] \ --cpu core2duo,+lahf_lm,+rdtscp,+pdpe1gb,+avx,+osxsave,+xsave,+aes,\ +tsc-deadline,+popcnt,+x2apic,+sse4.2,+sse4.1,+dca,+pdcm,+xtpr,\ +cx16,+tm2,+est,+smx,+vmx,+ds_cpl,+dtes64,+pclmuldq,+pbe,+tm,\ +ht,+ss,+acpi,+ds \ [...] I tried to add the following SandyBridge entry to /etc/qemu/target-x86_64.conf (taken from http://lists.gnu.org/archive/html/qemu-devel/2012-02/msg03765.html) [cpudef] name = "SandyBridge" level = "0xd" vendor = "GenuineIntel" family = "6" model = "42" stepping = "1" feature_edx = " sse2 sse fxsr mmx clflush pse36 pat cmov mca pge mtrr sep apic cx8 mce pae msr tsc pse de fpu" feature_ecx = "avx xsave aes tsc-deadline popcnt x2apic sse4.2 sse4.1 cx16 ssse3 pclmulqdq sse3" extfeature_edx = "i64 rdtscp nx syscall " extfeature_ecx = "lahf_lm" xlevel = "0x8000000A" model_id = "Intel Xeon E312xx (Sandy Bridge)" This doesn't quite match the host CPUs, since the model number of the E5-26xx CPUs is 45. But, anyway, qemu-kvm -cpu ? prints: error: feature "tsc-deadline" not available in set error: bad option value [feature_ecx = avx xsave aes tsc-deadline popcnt x2apic sse4.2 sse4.1 cx16 ssse3 pclmulqdq sse3] x86 Opteron_G3 x86 Opteron_G2 x86 Opteron_G1 x86 SandyBridge x86 Nehalem [...] Adding this entry also appears to have no effect on the used cpu settings when starting the VMs. I'm using stock F17 qemu-kvm-1.0.1-2.fc17.x86_64. The VMs are working, so that's not a pressing issue. I was just wondering, if full CPU support is something I can change myself using the stock qemu-kvm, or if I have to upgrade to the 1.2 virt preview release (or wait for F18)? Corinna

mdadm: How to access windows raids?
by Joshua C. 02 Dec '12

02 Dec '12

I have two 1tb disk that have been running in raid1 with the intel-p67-built-in controller. Those were created in bios (uefi) and are actually fake(software) raids. Windows sees only his own (ntfs) raid and everything is fine. Under linux I set the partition type to 0xfd (linux auto raid) and mdadm can successfully see and access the linux raid partion. However mdadm cannot access the windows raid and I have each partition three(!) times under KDE-Dolphin. So each time I click (unintentionally) on the real hdd-partition instead of the mdadm-partition I trigger the check of the raid, which takes about 3 hours. How to make mdadm access the windows raid and ONLY show the raid partitions in the kde-dolphin??? When I omit "rd.dm=0 and rd.md=0" on the command line then I see only the raid partitions under kde-dolphin but for some reason I cannot access them (so this is not a solution).

fedora books
by Brian West 02 Dec '12

02 Dec '12

Hello everyone I'd like to hear any suggestions you may have when it comes to a good book to learn the features of fedora. while there are countless books that teach you how to use linux in the general way. each distribution has its own unique set of tools and features. being that fedora has been known since the beginning as a distribution that stays on the cutting edge giving its users the latest software what book would you suggest to ensure i can stay educated on fedora?

Re: 3.7 kernels and kswapd

I am still booted in the 3.7.0-git kernel because it is keeping the disks from sleeping or it is properly waking the disks up before committing reads and writes. However, because of the current kswapd, building a kernel is taking an inordinately long time, so it will be likely 2 or 3 days on my old unicore Athlon64 3700+ before I can boot the new 3.7X

Printing multiple files results in hold
by Matthew Saltzman 01 Dec '12

01 Dec '12

Fedora 17, fully up to date. Shared printer from an F17 server. The printer itself is a network printer using IPP. Tried with two different printers, with the same result. Using lp or lpr to print several plain text files with a single command seems to result in the print job being held in the queue. Releasing the job with system-config-printer results in the job vanishing into thin air. Printing the files one at a time works as expected. Has anyone else seen this behavior? -- Matthew Saltzman Clemson University Math Sciences mjs AT clemson DOT edu
