Re: [CentOS] Does CentOS support dual graphics cards with 2 monitors each?

2013-04-07 Thread Richard Karhuse
I've got a triple-head set-up running where 1 monitor is off the internal Intel HD-4000 GPU and 2x monitors are off a GT550-Ti using the nVidia drivers. I could not get xrandr support to work (and attributed that to Intel / nVidia not co-operating). I found that using the nVidia xserver setting G

[CentOS] nfs timeout

hi, I use automounter to mount to many hosts /net//dir When the hostname is unavaliable it seems NFS gets stuck. I would like to set a NFS timeout (say 60 secs). If not available then error. I need to use hardmount but is there such a thing as NFS client timeout? -- --- Get your facts first

Hi Rita, As i m not perfect on this but still you can try once as i have written bellow You can modify a configuration file. Search for a word called "TIMEOUT " in "/etc/sysconfig/autofs". By default it is 300, you need to change according your requirement. # /etc/sysconfig/autofs TIMEOUT=60 :wq!

Yes, really. I've got hundreds of the damn things here at home, and I want to go through them and get rid of them all. But... to do that I want to read them. I have both a 5.25" and a 3.5" drive, both are plugged in, but in the BIOS, all I see is the 3.5". Fine, I figure I'll take care of those

Yes, they do because I'm using slow access to attack my servers. To your environment, you can use tcpdump to capture one connection to check if it's the slow access attack. If it's an attack, we focus on fixing that part. If it's the code problem, then, we can get back to the httpd daemon check
