We upgraded our kernel 2.6 based servers in the network, one of them didnt came back online after rebooting the system, it seems that the network module cant be loaded.

I tried booting with older kernels but the error stills
Last year I ordered a new server with Centos 4.3 and it had the kernel kernel 2.6.9-34.0.2ELsmp installed. It runned fine and I didn't update any packages since then.
Today I started getting a problem where both mysqld and kswapd0 uses very high amounts of CPU, spiking up to 100% and my memory usage is at 99% all the time. The problem seems exactly the same as the one mentioned in this thread.
In that thread the exact same kernel is said to be insecure and to cause this problem. I also came across a centOS bug that reports this problem with high cpu, mem usage and mysql & kswapd0 consuming all resources.
In the linked thread the person solved the problem by upgrading to kernel 2.6.9-42 using rpms but others recommended a newer kernel or a custom compiled kernel for CentOS.
Apparently when they used yum it said 34.0.2 was the latest kernel.
What should I do to upgrade the kernel, which version should i upgrade to, and where do I get it from? I won't be able to compile a custom kernel and I've only installed basic rpm packages before.
I'm starting a video/music streaming network and I'm wondering should I stick to American hosts or go overseas to say the Netherlands? Which would be able to offer me a bit more bandwidth for a reasonable price?
Also, if there are any top hosts here that could offer some nice bandwidth for this type of service for a reasonable price, let me know about them to.
My current kernel version is "2.6.9-42.0.10.ELsmp #1 SMP Fri Feb 16 17:17:21 EST 2007 i686 athlon i386 GNU/Linux". I want it to be upgraded since it is old. I have been told by our server management company that the latest kernel distributed from yum is kernel.i686 0:2.6.9-78.0.22.E. Can anyone tell me if this version is safe and secure enough? It is a CentOS release 4.7 (Final) server with cPanel installed.

View 2 Replies View RelatedI have a server running Fedora 4 and WHM/cPanel. I would like to upgrade the linux kernel to the latest version, so mosey in via SSH and type "yum -y upgrade". It downloads a few things and tells me everything is hunky dory.
Now, the version it says it is currently running is: 2.6.17-1.2142_FC4 #1 Tue Jul 11 22:41:14 EDT 2006
Is that the really the newest version available? Maybe I'm confused as to how this works, but if I go to kernel.org it tells me the most recent stable version of the kernel is 2.6.24.3. Is this because I am running FC4?
we have one box in hivelocity.net that has been down so many times this month that we were forced to remove links to siteuptime where we were once so proud of having a 99.7% uptime for 3 years in theplanet.
syslog shows that just before crashing, these entries were made:
kernel: kernel BUG at mm/rmap.c:479
kernel: invalid operand:0000 [#1]
dmesg also shows this:
...
Brought up 2 CPUs
zapping low mappings.
checking if image is initramfs... it is
Freeing initrd memory: 482k freed
NET: Registered protocol family 16
PCI: PCI BIOS revision 2.10 entry at 0xf9f20, last bus=1

mtrr: v2.0 (20020519)
mtrr: your CPUs had inconsistent fixed MTRR settings
mtrr: probably your BIOS does not setup all CPUs.

i've googled these messages and they point to ram problems.
hivelocity.net claims to have done diagnostics on the box and that there were no problems reported.
they said this is a result of a sys configuration problem made by us.
any ideas?
running centos/virtuozzo 2.6.18-028stab062.3
when i configure vmware it asks at one point for kernel header files. where would i find them to match the current kernel?
i asked at parallels forums but help there is very scarce. i checked openVZ repositories and they dont yet have headers for this version.
what are my options? i have one last windows machine left and want to run it in VMware.
I have a server running cPanel.
At the moment, I am been hosted on an unmanaged server (dedicated).
My server provider is offering $25/hour for managed support.
My Kernal and Centos have not been updated for a while and I am looking to upgrade both of them. I am wondering how long would these 2 jobs normally take?
any experiences to report about purchasing used / refurb gear from either Network Liquidators (nweq.com) or Network Hardware (networkhardware.com)?

I was adding another apache node to the cluster. All the nodes have RHEL5 installed on it. I downloaded the source httpd-2.2.10 and compile it using commands:

make
make install
After it is compiled without any errors, when i am trying to start it it's giving me error.

I have installed APF on box and set ports for in and out and enabled it.. of course, iptables is running from booting..

but when I check it like this

it said iptables is stop...even I start manually...
I am not sure APF is running correctly because of iptables..
What if i got a really good connection to this house i have in Sweden and bought some servers there, is it a good idea and would it sell? How hard is it to get a good connection, the house is in a fairly populated area of Sweden and i have partners who could help run it and do support 24 hours.
But its just a thought and we would start small. What do you guys think?
I have a wordpress site, and am trying to find someone good and reasonable price to design me a template for the website so I can still use wordpress but have access and control to everything.. I am going to buy a domain as well to hook wordpress up to it so I can edit themes etc.. I was looking at maybe using mmhosting..
Also, I have a forum, but not sure what type of forum I need to be able to arrange it and add and use features don't I can't now, so basically upgrade..

I have install VNC on my test VPS.
I download tightvnc and play with it just fine, everything working like it should.
But, I just want to SSH to the VPS and now it give me "Server unexpectedly closed network connection"

Can I just reboot the server and relogin again?
I have a dedicated machine with Xen configured... Dom0 stuff runs great.
I have a pre-made image from jailtime.org, with an ubuntu.7-04.img, ubuntu-7-05.xen3.cfg, and ubuntu.swap -- obviously, the actual image, the config file, and the swap file.
Starting it fails:
Code:
$ sudo xm create ./ubuntu.7-04.xen3.cfg
Using config file "././ubuntu.7-04.xen3.cfg".
The config file:
Code:
kernel = "/boot/vmlinuz-2.6.18-xen"
memory = "256"
name = "ubuntu"
vif = [ 'mac=00:01:02:03:04:07, bridge=xenbr0, vifname=vif1.0' ]
dhcp = "dhcp"
disk = ['file:/home/matt/vms/ubuntu-7.04/ubuntu.7-04.img,sda1,w', 'file://home/matt/vms/ubuntu-7.04/ubuntu.swap,sda2,w']
root = "/dev/sda1 ro"
Actually, a couple derivative questions here...
- Are the /boot and /dev/sda1 literal? That is, do they relate to Dom0 names (/boot on the server, and /dev/sda1, my "real" disk), or are they telling the new DomU what to call them?
- I don't want DHCP.... Do I change dhcp to "0" / "false," or do I specify an IP?
I've found a zillion guides out there, and they cover everything about setting up Xen, except for this one part, it seems?
I'm having troubles starting up MySQL. When I run..
# service mysqld start
I get..
Starting MySQL................................... [FAILED]
So I ran..
# ps aux | grep mysql
And did kill -9 for the running processes. When I try to run..
# service mysqld stop
I get the error..
MySQL PID file could not be found! [FAILED]
So I don't really know what to do. Does anyone have any advice about how I could resolve this issue?
I am thinking of starting VPS hosting.
I asked softlayer, they provide Citrix XenServer for hosting VPS on Linux (i prefer linux).
Can you please recommend software for providing VPS Hosting?
32 bit or 64 Bit Linux is recommended for VPS hosting?
I'm attempting to start my first website. The good thing is I'm not new to computers, or programming (my main experience is with VB/C#). I don't have any web programming under my belt, but if I had to learn a new language I'm sure I would be fine.
The website I have in mind is mysweetcar.com. It's meant to be for the most part a typical web forum. I would also like the option of adding Paypal or some other basic e-commerce services. I already have the domain name registered. Now, obviously, I'm looking for a host.
The huge number of available hosts and hosting plans is pretty overwhelming. In my research so far I've found quite a bit of inconsistency and what seems to be false or misleading information. Almost every "review" site I've visited feels like its been paid off by the web hosts. In general I'm having trouble finding objective and unbiased analysis.
Heres a good example of my general confusion: The web host ixhosting.com offers 2500GB monthly transfer for only $6.45 a month. Yet on another website, hosting.com, the data transfer is only 25GB a month, and the plan costs $17. Can there really be such a huge difference? I also don't see numbers for bandwidth, for example with the 2500GB plan it wont matter if the bandwidth is poor and the site runs very slow. I also don't trust that the web host will be faithful to the transfer rate they give me. Is there a way I can independently verify what my transfer usage really is?

I have hosted alot of websites for the past few years.
I first started off with virtual, then shared, and then dedicated. Then finally I purchased my own set of servers and managed to get them colocated in a server datacenter. This was a very big step for me, as I had to study linux and learn how to setup a server from scratch.
I am ready for the next big step, having my own colocated server system. Therefore, I would rent out a space, setup a connection, and them have everything running.
However networking is an issue, since I don't have any schooling for it. But I am willing to learn.
When setting up a server colocation, in what form does the main internet line come in? What kind of networking hardware do I need to split the incoming connection? I already have a network switch, would that be enough? Or do I need something more?
I am in the process of starting a new web site and I would like to know exactly what I should need to know about webhosting, such as:
1) The best one in terms of Price.
2) The simplest one to deal with (if it so matters)
3) What annual fees should I be looking at?
4) Can performance depend on web hosters?
5) Does country of hosting matter?
etc...
I want to start my own web server it will be hosting company for future. I will host to 100-200 domain and web sites as begining. Os will be linux red hat with cpanel.
My system will be;
HP ProLiant DL385 G2 (438816-421 HP DL385G2 2220) Two
opteron cpu's
Ram 8gb
HDD 8x HP 146GB 10K SAS 2.5 Hot Plug Hard Drive
Fire wall Cisco Pix 515e
My questions;
What can I do for this server works non stop 7/24 if any problem happen hw or sw base?
How many of same system I have to buy?
For example if I need to buy 2 of them. What kind of setup I need? (Like mirror, load balancing, vps, proxy) or if there are some hw base systems, what is your succes?
