i am using nfs on my network with server ip 192.168.1.10 (the exporting server)
and i am mount nfs partition in /etc/fstab and when i login into console using the
alt ctrl FX
i continously get the following error
lockd: cannot monitor 192.168.1.10
moreover the mount is somewhat irregular on host systems as i am mounting home directories on all the systems on network and authentication using NIS, when i try to open firefox in console it continusly gives this error and firefox doesn't open and then after a reboot again of the client workstation firefox opens
I'm have some desktop computers sharing my Centos 5 server diskpace through NFS. From time to time, without any warning, lockd bugs and all the users that are using GTK applications like Firefox,Gnome.get stuck.
My first atempt is to restart the NFS, but locked files persist because I can kill the lockd pid process, even using root account , I suppose this is because it's a kernel process. Here is the message error I get when restarting NFS matrix kernel: lockd_down: lockd failed to exit, clearing pid
I have been using 10.4 as a Linux NFS server to share it's storage with a number of Mac computers we use in the office. All the Macs are configured to connect to the Linux server using the mount_nfs command in terminal.I have been using this method to transfer files to and from the Linux server for a while. Today, I installed a number of standard Ubuntu updates / security patches per the standard GUI update tool.
Now, I'm getting "nfs server 192.x.x.x:/media/video: lockd not responding" error messages. I have not seen this error before, and I haven't changed anything else about the configuration of the Linux server or the Macs with the exception of the installation of the security patches.
I boot some Slackware with PXE. All work fine except i can't fix the client lockd ports.NFS is compiled inside the kernel, so all modprobe.d options are useless.But rpcinfo -p on the client side shows me totally different ports.On the NFS server, the ports are ok, as i appended lines in /etc/lilo.conf Server and client kernels/modules are identical.
Is there any way I can monitor what is happening inside one tty using my current tty, like we have 'portmir' command in AIX. I think there will be definitely one in Linux.
I have CentOS installed on my laptop. I hooked up my TV via VGA and it works, just not as I'd like it to. The left side (on the tv) is cut off, like the image is justified too far left. I want it to be centered, but I also want to use a different resolution. You see, I use a netbook, and thus my laptop screen is tiny, meaning some things cant fit in the same window without scrolling. I want my TV to fix that for me.
Two days ago I switch from Arch Linux to CentOS. Everything is working as it should; except that I can't get my second monitor to work. I use two monitors (VGA: LG-W2241S, DVI: ACER-AL1906) connected to one video card (GeForce 7300 SE).
I have a perl program that I need to an eye on so it run 24/7 and restarts if it stops at any time. I have Webmin installed and I am looking into Mon but it seems it only monitors services like "httpd" and "smtp" rather than a file.pl file which runs. Actually the file creates a pid.log in /var/log/ which has the PID number in it.
Since Monit doesn't come on webmin I am not sure what I need to put in it's config file to monitor my file.pl.
Trying to monitor mysql 5.0.77 with nagios 3.2.1 under CentOS 5.4. Everything with nagios has been running without a hitch for me, however, when I added the following to /etc/nagios/objects/localhost.cfg to try to monitor mysql, I get an error that reads "Running configuration check... CONFIG ERROR! Restart aborted. Check your Nagios configuration."
define service{ use local-service host_name localhost service_description MYSQL check_command check_mysql notifications_enabled 1 }
This is pretty much what I added to monitor other things on the server such as ftp and smtp, just switched out check_smtp with check_mysql, etc.
I am somewhat new to CentOS, but I have read a lot of web pages and tried a good number of things trying to solve my own problem. I have made it worse a few times, but never better. I have an envision 1440x900 LCD monitor and a S3 Savage video chip on the motherboard. In System->Administration->Display->Hardware I am using generic LCD Panel 1440x900 and the video card is listed as "S3 Inc. VT8375 [ProSavage KM266/KL266]. I believe both of these to be correct. I have added the mode to my xorg.conf
The problem is, under System->Preferences->Screen Resolution, the mode 1440x900 does not appear. The highest resolution is 1280x768. Does the S3 Savage just not have the ability to produce 1440x900?
I installed Centos 5.3 x86_64 and jumped out to me the problem with which I cannot manage. After about 10 minutes from the start of the system becomes detached to me the monitor, the keyboard and the mouse.Itself system in himself works and I have a possibility to connect myself across ssh or else mappings of disks.
I'm running CentOS 5.4 on an Atom-based motherboard with a quiet, low-power PSU. As the only fan left is a 40mm fan to cool the Intel 945GC chip, I'd like to run a utility to monitor the 945GC and HD temperatures. Ideally, it should be able to run the 945GC fan faster when it's needed.
I am having video issue with ubuntu 9.10 and centos 5.4 cannot get resolution higher than 800x600 on Viewsonic vg930m monitor...The first time I installed ubuntu 9.10 worked great, since then no better than 800x600 on both linux distros. Any ideas it is very annoying, like using web browser on a small tablet pc....This monitor works great with opensolaris, though.
Using both distros in virtualbox right now but even if not virtualized install on hard drive I cannot get higher than 800x600...Driving me nuts.
I alrady set up centos5.4 on Dell R710 , My server set Raid5 ( 3 HDD ) . But I don't know how to monitor raid status.Centos have software for monitor hardware raid?
We have a quad core Intel Xeon E 5410 processor running on recently installed centOS 5.5. Machine can't be pinged all of sudden and when we switch on the monitor, no signal on it, even no response on keyboard. We thought the problem accorded with abrupt temperature changes, is it so? But we have similar machines running efficiently under same temperature conditions.
I am using LVM2 Clustering to mirror logical volumes between 2 different storage arrays ( iscsi target hosts). Everything is up and running fine, but I would like to be able to monitor the status of the mirror(s), and "re-sync" them if necessary.
I have attempted the locate the information from Google. From what I have read, lvdisplay -v should tell me whether the mirrors are in sync, but it either is not, or I am simply miss reading it. I have come also across information stating lvchange -m [ 0 | # ] should be used to add or remove mirror copies. Is the is correct / only way to "resync" a mirror, in the event that I can determine the mirror is actually out sync?
For those who are familiar with Symantec's VERITAS volume manager, I am looking get the equivalent information related to plexes from vxprint, the equivalent function from /etc/vx/bin/vxreattach -br, and the progress information from vxtask list. I hope the information is currently "search challenged", or I am simply not fully comprehending what I have found.
I haven't manually configured XWindows in a very long time, so I'm not very certain what I need to do anymore. Hopefully someone can provide some guidance. I just built up a new system that I'm trying to connect to a 47" LCD TV that provides a VGA connection. When the computer starts booting all of the text comes up just fine (1 or 2 characters on the left are chopped, but otherwise fine). When I tried to run the installer for CentOS5.5 I ran into a problem. The monitor(TV) wasn't getting a proper signal to display XWindows. In an effort to keep going, I reconnected the PC to an old monitor and did the install from there. That worked no problem. I ran all the latest updates hoping that maybe this was fixed in a patch. I then shutdown and reconnected to my TV. no luck. When it starts XWindows the screen doesn't display anything. I've tried fooling around with modifying the xorg.conf and adding an explicit "Monitor" section and set it to 640x480 with a VertRefresh of 60 (which is supposedly an acceptable format), but no luck. Can anyone provide any guidance on how to solve this problem. BTW I do know that the VGA connector on the TV works just fine because I can hook up my laptop (Windows XP) to it.

Brand new Dell XPS 15 laptop. NVIDIA GeForce GT 420M graphics card with Optimus. 15.6HDF TLF LCD L501X screen. Centos 5.5 64 bit, text install.
I downloaded and install the NVIDIA graphics driver NVIDIA-Linux-x86_64-260.19.29.run When I run system-config-display the display configuration appears but is very, very faint. Increasing screen brightness has no effect.
I am now installing the CentOS5.4 with a DVD on a Windows machine. The video card is ATI Radeon HD 3450, and monitor is Dell 1909W. During the install, after recognizing the ATI card, and starting the xserver, the screen came up with a message saying: " The current input timing is not supported by the monitor display. Please change your input timing to 1440X900@60Hz or any other monitor listed timing as per the monitor specification. "
However, in Windows XP the monitor is configured as 1440X900@60Hz, which works well. Due to this problem, the GUI installation cannot proceed. And how can I fix this problem if I manage to install in the text mode.
I am trying to install nVidia drivers on CentOS 5.4 and it is requiring kernel-source # lspci | grep VGA 01:00.0 VGA compatible controller: nVidia Corporation G98 [GeForce 8400 GS] (rev a1)
For the installation of kernel source, I have followed the steps on [URL]. I followed the steps under 2.1 and they worked for me. Now what can be done for the installation of the kernel-source package. When I am trying to install nVidia drivers, I am getting error, following are lines from installation log of Driver.

I've installed CentOS 5.5 64 bit on a Dell Latitude e6410. This model only contains Intel HD Graphics, not the extra Nvidia card you could also buy in addition. The getinfo output can be found here:[URL] Initially X11 did not work at all (blank screen), but using hints from other posts in this forum I was able to fix this by editing the file xorg.conf using the vesa driver, although I still do not get the native screen resolution of 1200x800 (I alwas get 1152x768).
Now I want to add an external monitor (Samsung Monitor connected via DVI, screen resolution 1680x1050). Unfortunately as soon as I try to configure the dual head mode using the system-config-display tool after restart of the X server there will be the the blank screen again. I tried various drivers with no luck.Has anyone succeeded setting up dual head on an Intel HD Graphics machine? I understand that this hardware is quite new and and would be easier to set up with more recent distros, but I would like to stick to CentOS, but cannot wait for CentOS 6.
I just started setting up a linux box in the office...I have some experience with ssh commands but not setting up a linux system and stuff.The box is connected to our network but I have no clue how to make windows & osx talk with it. How can I go by doing that and also setting up an apache server to be able to connect through network. Right now I have apache/linux/mysql running it works when i go to localhost, but I would also like to let all the computers in office to access it. I would guess that will deal with virtual host which I know how to setup. I just need to setup an IP.
I just recently purchased a DELL PowerEdge 2850 and have tried installing CentOS 5.4 on it. After the install completes and it does a first boot I get the following error on the DELL console: PROC 1ERROR, PROC 2ERROR E07F0. The monitor remains black and the system hangs. Just out of curiosity I installed Fedora 11 on it to see if it was a hardware problem. Fedora installed and booted no problem. I rebooted with Fedora installed several times and left it running for 24 hours. Everything is working great. Is there something I am missing in the CentOS 5.4 install?
Below is the Hardware Config: Dell PowerEdge 2850 PERC 4eDi RAID Controller 8GB PC-5300 ECC Memory 2 Intel Xeon CPU Dual Core 2.8GHz 800FSB 4MB Cache - SL8MA ATI Radeon 7000 Video Card
I have repeatedly installed CentOS 5.5 64-bit on a Dell T3500 with an nVidia Quadro FX 580, in an attempt to get dual monitor support to work to no avail. Everything works fine when just one monitor is plugged in and I do not try to enable or plug in a second monitor. I have installed the Dell DKMS, and the Dell recommended drivers (from Dell site) on one installation, I installed the nVidia drivers (from nVidia site) on another, and have tried with what CentOS loads by default on another. The results are the same every time: When I reboot as directed I get a black screen. I can recover by hard shutdown and unplugging one of the monitors, but that doesn't solve my problem. Has anyone had a similar experience, or have any helpful guidance? I am not very Linux savvy. This is for multiple machines in a corporate environment.
