spice-guest-tools for widows 8?
Hi All, spice-guest-tools-0.52.exe does not support Windows 8. Anyone know of a version that does? No QXL driver is annoying. Many thanks, -T

The unfortunate reality is that for a least some of these products, the only well support environment is MS Windows, sometimes Mac OS X, and only lastly, open systems such as Linux or the BSD variants. In the case of Nvidia, the CUDA compute engines as well as the professional switched stereoscopic 3D do have a strong advertised support for and deployment under enterprise Linux. However, the reality is that the compatibility with existing Linux environments, e.g., SL, is not what one might desire for a supported product. However, if enough of us who professionally use SL and other TUV EL variants sufficiently complain, it is possible that Nvidia will make all of this work -- provided the profit is there for the corporation. Unlike SL and related efforts, as far as I can tell, USA for profit corporations, such as Nvidia, only exist for one purpose -- that all overarching profit. All else is just lipservice. (This may not be the case in some EU nations in which for profit corporations are required to have real workers share in the shaping of policy and in real business management, unlike the Gompers model in which all the workers are concerned with are working conditions and financial compensation -- not the direction or societal value of the corporation.) The above is not meant as a political statement or a statement of philosophy -- it is meant purely as a statement of factual reality -- a reality within which we must work if we want them to 'fix' what needs fixing.

If they support RHEL, they support SL as well (not officially, but if the driver is working with RHEL it should also work with SL). If the driver isn't working with RHEL as well, file a bug at Nvidia and tell them that they please fix the bug. Everything else is a waste of time. If Nvidia provides a driver for Linux, they are responsible for the driver. If the driver is bad, ask them to make a better one. But this is nothing where SL nor TUV nor anyone else in the community can help, especially if the driver is closed source, then it's up to Nvidia and no one else, quite simple.

Microway, just to mention one company, supports CUDA under Linux. We have one of their machines here, and one of our researchers is working on using it under EL6 with a fairly large CUDA GPU setup. He's still early into his research, but I'm sure I'll hear about any issues he may have. In case you're not familiar with them, Microway's Tesla information can be found at http://www.microway.com/tesla/ They've been in the business a long time. This is the first one of their machines we have purchased, so we'll see how well the support works. And SL, along with CentOS, qualifies as an 'enterprise Linux.'
Re: Cannon IR 5055 driver
i was slightly ;) surprised as well - since this Cannon printer is relatively old model ( I think 2009 ). Si today i put a side 4 hours to learn the intricacies of CUPS. http://www.openprinting.org/download/kpfeifle/LinuxKongress2002/Tutorial/VII.cups-help/VII.cups-help.html#Supply http://fedoraproject.org/wiki/How_to_debug_printing_problems and ended up with tons of cumbersome debug information ... the solution was simple - i picked the next model in the list of the available models in Print assistant ( or whatever that gui app is called). so instead of selecting 5000 model, i choose IR5570 and it nicely printed the test page. oh well .. just a click away :) On Tue, Mar 26, 2013 at 1:18 PM, Paul Robert Marino prmari...@gmail.comwrote: Well vendors often create X86_64 packages that have i686 dependencies mostly because the weren't paying attention when the compiled it, so that happens. As far as cups just not working that's rare. Often cups may have odd output because a vendor decided to make a tweak or some other odd reason which you can usually tinker your way around. That said without seeing the logs I can't definitively tell you but most likely its a network issue such as trying to use a NetBIOS name instead of the IP address. -- Sent from my HP Pre3 -- On Mar 26, 2013 12:17 PM, Andrew Z form...@gmail.com wrote: hello, i'm trying to hook up a network Cannon IR2055 @ the office.

Re: memory per process/core
Just a stab in the dark, but did you check the Shared Memory kernel parameter (shmmax), type cat /proc/sys/kernel/shmmax. We have it set very high so that any process/thread can use as much memory as it needs. You set the limit to 1 GB without rebooting by typing echo 1073741824 /proc/sys/kernel/shmmax or modify /etc/sysctl.conf and add the line kernel.shmmax = 1073741824 so remains after a reboot.

how to find internet dead spots
Hi All, I have a Cent OS 5.x server sitting on a DSL line acting as a firewall. I have noticed that there are dead spots, up to a minute, every so often in their Internet service. It could be a storm on someone's part, but the worst they run is IMAP. No music; no video. Is there a utility I can run to map this? Many thanks, -T
AD Integration - what do you do about user/group pairs like puppet/puppet ?
So we're working along our SL6 and AD Server 2008R2 integration, using SSSD for authentication and such. We've realized that AD won't allow groups and users to have the same name. For common software like puppet and quemu that has this setup, what do you do? Change the program configuration to use a different group name? Do some hackery with OUs and sAMAccountNames and have it use gids (do the right things do this)? Technet says sAMAccountName must be unique and cannot be munged... -- James Pulver LEPP Computer Group Cornell University
Re: AD Integration - what do you do about user/group pairs like puppet/puppet ?
WellThe same user should be able to login from multiple clients at the same time so as long as the gids and uids on your file system are consistent across the board that's a non issue.But a word of advice DO NOT PUT THE USERS FOR YOUR SERVICES IN AD OR ANY OTHER LDAP SERVERIts a horrible idea because if you loos LDAP connectivity and th SSD cache fails you server turns into a paperweight. That and the nature of how file system lookup of gid uid maps and acls work on Linux and Unix weren't designed with remote authentication in mind so every file access generates a lookup query SSD alleviates this but again if SSD fails you will fall back to doing a DOS attack on your LDAP server. This is one of the old common problems people had with nscd the default tuning options were optimized for local file based lookups and not for nss or LDAP so it would get over welmed and would either crash or worse get into a loop where its trying to answer expired requests delivered via the memory mapped file instead of the socket. By the way that memory mapped file default setting instead of using the socket was the actual cause of most of the issues but I digress.Only use LDAP for users that actually login and never for root.-- Sent from my HP Pre3On Mar 27, 2013 3:56 PM, James M.

Re: how to find internet dead spots
Hi Todd,
If you mean the dsl goes out for a while, what I've done is pretty low
tech but works for reporting downtime.
A cron job from inside that pings a couple of servers on the outside and
one on the outside that pings the server in question. I usually grep
for the summary line and redirect it out to a log file.
Soemthing like:
#!/bin/bash
ips=example.com another.example.com
for ip in $ips; do
dat=`date +%Y%m%d %H%M`
res=`ping -c 3 $ip | grep loss| awk '{print $6, ,, $10 }'`
echo $dat , $ip , $res /home/joe/ping.stats
done
