Corei7 Kernel Config Option
Jun 16, 2009
I just got one of the new corei7 boxes, it looks pretty sweet. I am compilig a custom kernel now, doing linux-2.6.29.4 (latest grsecurity test patch kernel) and I do not see an option for the corei7, just Core2/Newer Xeon. I had been googling and seem some posts about kernels now supporting i7 but no info on the config. I do know the installed distro - centos5 64 bit, it ran fine on the first old kernel and latest kernel got in yum update.
Does anyone know of any patches or anything out there that will help harness the full capabilities of the i7? Or has anyone else compiled custom kernels for your i7 without issue and what processor type did you choose?

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
PCI: Using configuration type 1
mtrr: v2.0 (20020519)
mtrr: your CPUs had inconsistent fixed MTRR settings
mtrr: probably your BIOS does not setup all CPUs.
mtrr: corrected configuration.
...
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.

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 using Plesk on one of my webhosts (GoDaddy) and would like to know if anyone knows of a good Cpanel Fantastico-like option that allows you to update a string of sites with the latest updates. I'm more familiar with Cpanel.
Do you know of any?

I'm fed up with the overloaded 1&1 shared hosting, looking into VPS now as I'm finally getting serious about one of my sites.
I tried offloading scripts and images to amazon s3, which helps a bit, but any sort of php application processing is painful.
Admittedly, I haven't implemented caching at all yet and my query count is definitely bad but even so load times seems excessive as the site isn't getting any real use yet, just me testing (and I will make heavy use of caching for all entry points in the near near future).
My must-have:
-PHP5
-2 seperate MySQL databases
-htaccess/mod_rewrite
-fast initial response time on loads
-unlimited subdomains would be nice
Don't really care about the control panel as long as it does what I need. I'm fine with command line and managing myself... looking for a cheap option that will allow me to grow to a medium sized site before I consider a full dedicated option.
Also, don't need an outrageous amount of bandwidth as I'm using S3 for css,js,images, and video right now.
I will be running two domains on this site... one is the actual site and one is a single sign on gateway that won't put too much load on the cpu but needs to serve up pages in timely fashion.

if I should continue paying an extra $25 per month for Cpanel. Is it that hard to do without it? All I really do with Cpanel is configure Spamassassin, setup emails, and backups.

I have a client that has one main ecommerce site and search engine ranking is very important.
They also have about 60 other domain names that are relevant to their main domain. example: pizzapie.com & cheesepizza.com.
The question I have is what would be the best way to utilize these domains without getting search engines mad (lose rank). Mirror? Forward? Or should I populate them with the same files? Or same files but change the text around as much as possible?
The last question is basically the same but they also have international domains with the same situation; pizzapie.jp, pizzapie.nz, etc. Would this be any different or does anyone have suggestions how to treat international domain names for ranking in US & the corresponding country?

I have bought a Master Reseller recently.
I have some technical question in my mind regarding backup.
I will start step by step.
1) I login to the WHM.
2) I click to WHMreseller Master Resellers placed on the bottom of the left menu.
3) There I saw some options at the bottom , 'Migrate' , 'Backup' ,'Change Owner', 'IP Delegation'
4) I clicked on 'Backup'.
5) There I saw two check boxes:
Enable Weekly Automated FTP Backups
Enable Weekly Automated Local Backups (will only run if cpbackups are disabled by root)
My questions are very simple:
Q1) What these two check boxes mean ?
Q2) If i check 'Enable Weekly Automated FTP Backups' and save these settings then every week , back of my all cpanels including cpanels of reseller will be generated or wht?

After I post my desired subdomain as mysubdomain.domain.com on /mysubdomain.domain.com/
I get "Error: phpinimng failed: Usage: phpinimng [options] [php_ini_file] phpinimng: error: no such option: --global-config" on main window.
Tried to search how to fix this error, i managed to find that there is also " missing or incorrect /usr/local/sb/include/init.php ". As for this error this doesn't work [URL] .... It's already correct permission 755.
The subdomain appears only in DNS records on my domain. But not in the main plesk panel window.
OS is Debian 7.6 and Plesk 11.5, mysql runs over sock
Maybe I could create manual configuration over ssh in /var/www/vhost/ dir ..?

I'd like to back one of our servers up using S3 but I'm not sure the best way to go. Server is using CPanel. Obviously I want to keep costs down.
I need the files to be secure, backups need to be nightly incremental, and I need to be able to restore to another CPanel server fast in case of hardware failure. CPanel supports FTP for backups. I currently back up to another server, but I want to move to the cloud.
Specific questions I have:
1. Any recommendations on a cloud backup service (S3, Rackspace, etc?), and why?
2. Any recommendations on tools? I want this to be simple to set up. As easy as setting up an FTP account.
3. Is there another option I should consider? That server has about 62GB of data on it to be backed up.

What benefits/features do you think an unmetered dedicated server will need for a starting file hosting website that will market agressively/daily in forums/warez with the free benefit of 500mb of free hosting?
Simple/ but important details:
*I would like to manage the server myself with cPanel/WHM + Fantastico as I control about 60 of my websites in hostgator shared baby account(however, hostgator prices are way to high for dedicated)
*I have never had experience with dedicated server management and only have done dilligence as of today
* My budget is from $65.00 to $100.00
Will this next unmetered example be the perfect solution for fast uploads/downloads to start?
CELERON-3.06GHZ
1 GB RAM
80 GB IDE DRIVE
Unmetered
5 IPS

I currently have one server at The Planet, paying 147/mo. Anyone know if they have any options to pay every 6 months at a slightly discounted price? I have no plans to move, so figured I'd look if I have that option to save money. Suppose it's something I could of asked them directly but thought I'd ask here in case anyone knows or has experience doing this, and whether or not it's worth it.
