I just install CentOS 5.4.
The first message it gives after grub is Quote:Memory for Crash Kernel (0X0 to 0X0) notwithin permissible range
How do I get rid of this message during boot. I have tried the system-config-kdump command but it gives me a "no command found" reply. I am using CentOS 5.4

I want a controller supported by the kernell, plug and store.I found two boards looking interesting with a cheap price:- Dawicontrol DC-4320 with a SiliconImage Sil3124-2.- Promise FastTrak TX2300.The DC-4320 is better because has 4 sata ports Vs 2 ports for the TX2300, but this is not a big problem for me because i only can add two more disk on my box.I, am planing to buy a 1,5 Tb seagate disk (ST31500341AS), dont know if it may be a problem with the size.
View 6 Replies View RelatedMy server crashed last week and I'm trying to diagnose why. /var/log/messages contains the following error messages, which indicate that the server's memory peaked. I would like to discover what process caused the memory peak. Being that "httpd invoked oom-killer", can I conclude that httpd was the cause of the memory peak?

Something is running my memory up and causing my load to crash my forum. I keep noticing this error and have no clue really how to go about fixing it.

Could this be causing my CPU to run high? How would I go about fixing an error like this or is it even doable?
Basically I have a machine with 16GB of RAM and have just discovered that using all of it can crash the whole system over one process. How could I run a process on the system in such a way that if more than 90% of system memory is used, the process immediately crashes?

View 6 Replies View RelatedI want to plot a set of data in only one plot.The problem is that some points of the data should be better plotted in a linear scale (lets say 0 to 100,000) but there are other data points that, exceding the value 100,000, would be better plotted in a logarithmic scale, as they goes in the range 100,000 to 500,000,000. Let's say the data is:
Code:
X Y
0 100
10000 80

Is there a way to plot all these points in the same plot in only one X-axis showing two different ranges in that axis: linear: 0-100,000 logarithmic: 100,000 - 1,000,000,000?The axis would be read, for example, as:
Code:

Installed CentOS 5.4 x86-64, installation is fine. First bootup after install always fails (after a few messages are displayed) with my monitor showing an "out of range" message.I know exactly what to fix (sync values in xorg.conf) and what values to enter there, but what I can't figure out is, how to get to a stupid prompt! Or a smart one for that matter.Also, I do get a message (before the "out of range" message) from CentOS, telling me to "press I for interactive startup" - but all that does is print as many "I" on the screen as I press. And did they really mean "I" and not "i" for this?
I hear great things about CentOS and if you can help with this silly question - How to get to a prompt - as easy as it probably is for you all, it would help me a lot.
I want to build a bash script, which can ping a range IP adresses which will be filled in by the admin. If there is no IP-adress filled in, then the script must ping the subnet where the system is logged on. So if my ip is 192.168.1.6, then the script must ping from 192.168.1.1 till 192.168.1.255 Or else, if there is given a beginning and ending ip it must ping that!
The first part of the bash script is to ping a given range (see below). But there is one problem, how can I tell the script to ping from $begin till $end, [..] is of course wrong! But what must be filled in there???
echo "Enter beginning IP-adres:"
read begin
echo "Enter ending IP-adres:"
read end
ping -c 1 $begin [..] $end
The second part is to find my own ip and ping the whole range.. How to do that? I only can find my own IP, but I cant ping the whole range,, how to do that?
#!/bin/bash
ifconfig | grep 'inet addr:' | grep -v '127.0.0.1' |
cut -d: -f2 | awk '{ print $1 }'
Last week my server crashed. I'm trying to diagnose the cause.
This is the relevant error message in /var/log/messages:
Code:
I'm assuming that I can conclude, then, that apache/httpd was the cause of the memory leak?
Next, I've been tracking my memory usage. Using top, this is an average memory load level for my server:
Code:
I'd like to confirm if my understanding of this data is correct, because Plesk indicates that my memory usage is only 50% or less. (Though I have read a number of reports indicating that Plesk's measurements are frequently wrong.)
Top says: Of the 2,073,156K total memory, 1,982,572K (95.63%) is being used, 90,584K (4.37%) is free. Of that sum, 421,948K (20.35%) are being used as buffers. Additionally, of the 2,096,472K of Swap, 60K is used, and 887,700K (42.34%) is cached.
My questions: Is my memory actually being 95% used? Or is the buffered quantity (20.35%) not a use of physical/virtual memory? (i.e. is it disk usage?) Does the amount of cached Swap influence the percentage of physical/virtual memory being used?
In other words, who is correct? Plesk says I'm using 40-50% of my memory, whereas top says 85-95%.
I just ran into a weird problem with a CentOS 5.5 64-bit server running VirtualBox 3.2.8 (I would run Vmware Server 2.0.2 if not for the well known fact that Vmware doesn't care about its Server line anymore and it doesn't run on CentOS > 5.3 without major splits). I currently have two guests in that VirtualBox setup, a CentOS 5.5 64-bit and a Fedora 13 64-bit. The CentOS 5.5 guest shows less memory available than configured. If, for example, I give the virtual machine 512MB of memory the guest OS only recognizes 380MB. If I give it 768MB it only recognizes 637MB, and so on. I don't have that problem on the Fedora guest - 1024MB configured, 1024MB available.
View 13 Replies View RelatedI have a DHCP server running on CentOS and for some reason it is assigning the highest number from the IP range as a first one?
- range 192.168.1.20 - 192.168.1.50 - so the first IP on my PC recived from this DHCP server was .50 - is it normal behaviour?
Config file:
On my CentOS 5.4 box I run dns, ssh, and smtp servers. This box also has to be able to resolve and browse websites. So basically it needs iptable rules for
TCP 22 25 80 443
UDP 53
My question is, which of these services work nicely with connection tracking? I'm a little confused about how connection tracking works. For example say this iptables rule for smtp
Code:
iptables -A INPUT -s 0/0 --sport 513:65535 -d $myip --dport 25 -j ACCEPT
versus
Code:
iptables -A INPUT -s 0/0 --sport 513:65535 -d $myip --dport 25 -m state --state NEW,ESTABLISHED -j ACCEPT
So with connection tracking what exactly does it do that my first iptables rule does not do?
Also for centos is that port range correct? 2.6 Linux kernel randomly chooses a port 513-65535 when it connects to an external smtp server or say browses a site.

CentOS is up to date as of beginning this week. Doing a quick net check suggests HW-problem ( HP DL380 G6), but I've tested both memory and cpu(s) without errors. We also had the same problem on Scientific Linux 5.4.
I am using CentOS5.2 and gnome 2.16, sometimes (not very often) when I open something and close it by clicking the CROSS on the top-right corner. The application crash and I lose all control (no keyboard anymore), I have to reboot the system by reset the machine. What's going on?
Yesterday, when I logon as root and run service setup, after I uncheck a sevice in the list and then start it, I click the CROSS on the top-right corner of the window, it popup a window (in the background) to ask me to save it or not, but then I total lose the control, no mouse, no keyboard. I try to reset the machine many times, but everytime when I repeat the same operation, it crash again. Seems that if I don't close it, everything would be fine!!!!
when open an pdf and close the tab/windows at firefox I get the error at syslog: kernel: npviewer.bin[21396]: segfault at 0000001000000000 rip 00000030abe2646c rsp 00007fffb0978ca0 error 4

My exercise below is to check if glxgears crashes xorg of CentOS5.4 with Intel GM965 Chipset. Apparently I don't have luck in this case. Since the exercise failed, it means I will still stick to CentOS 5.2 (residing on a different partition) for a while, even though CentOS5.2 crashes glxgears too. After "yum upgrade" (done after moving all repos in /etc/yum.repos.d to elsewhere except CentOS-Base.repo and CentOS-Media.repo), I ran glxgears that consistently crashes CentOS5.2 xorg, an issue that upset me quite a bit.
During upgrade, I saw a line "grubby fatal error : unable to find a suitable template". I guess the my grub.conf is too confusing for the installer, but that is not big deal, I just used the kernel number 2.6.18-164 where it is applicable. Even this this new update, glxgears still crash the xorg (the screen froze and then a new login screen reappears). With this I am sure the 3D application might still crash the xorg from time to time. (I can still revert to CentOS5.2 with a tar file, but I am still thinking to just upgrade to Centos5.3 but I don't know how.)

I using only Livecd CentOS 5.4 and my system crash in day about ~3-5 times , so I tired and want to know why this happen.

View 1 Replies View Relatedthis message is a bit long but I've been pulling my hair for 2 days now. I am installing Centos 5.3 on a Dell Powerege R610, x86_64 flavour. That part goes well. next is testing backup & restore. I've tried MondoArchive, that I used on other OS, but it fails to remount the LVM correctly, and disk formatting fails. Now, I am trying another way: boot with centos 5.3 i386 live cd, take the disks online, cpio to a usb file everything but: /tmp /proc /boot /dev /etc/fstab /etc/mtab
then, reinstall a fresh centos to erase the disk (crash simulation) and to simulate the initial restore I would do after a crash. From there, I go again with the livecd, mount r/w the logical volume, cpio -i all my files, and reboot. It sort of goes well. system reboots correctly - it loads all my drivers (even asterisk & dahdi and the T1/E1 card light goes green...), starts KDE, but from there I get an infamous error message preventing me to log in "Your session only lasted less than 10 seconds" - looking in the details, i get this message "could not exe /etc/X11/xinit/XSession default' - but I dont think X11 has so much to do with it...
When I go to a text console (ctrl alt f1), and try to log, no luck either - and no time to see why. I've modified initrd to level 1 - there I get the single user prompt, that's ok - but init 3 brings me to a screen where I cant log (either with root or a user) - there is a clear difference between an incorrect password and a failed login - the later, as soon as I enter the password, I return to a login prompt Now my questions. 1/ how can I make a "system backup" of Centos 5.3 x64 -ie after a crash, I want an image tha t I will restore and bring back OS + Applications (data can be backed up separately) 2/ what is wrong with my restore thru livecd ? why cant I log into the system ?

I've installed Centos 5 on 2 serveurs.The first one export the file system with NFS.The second one use amd to automount the filesystem with the link/net/@IP/Shared/folder/On the client side, I mean the second server, there is some logs into the messages system telling us the the process gam_server as crashed (segfault)On the first one, sometime, NFS Freeze, and nothing is available. This need a Hard reboot of the server in that case.
