umask are the default permissions that are applied when a file or directory are created. To see this in action simply just "touch filename" or "mkdir somedir" and you'll see what default permissions are applied.
The first thing Ialways tell people you should know is to NEVER change the defaults unless you are making them more restrictive. But they work well and if you change the defaults you could end up creating a file without permission to read........

1.) First install nfs-utils
yum -y install nfs-utils
2.) Configure nfs share

It's always bothered me how Wordpress basically forces the user to provide their hosting credentials to install themes and plugins. How do know for sure the data is not being saved, intercepted and being provided backdoor access to the NSA or other agencies or even just being misused by others with access?
Here's how to close the security hole above and if you're already given Wordpress your credentials make sure you change everything associated it with it. Eg. change your........

This happened after a customer migrated their hosting and the issue was being unable to access PHP sessions.
Warning: session_start(): open(/var/lib/php/session/sess_3e0oms763m6mrqekdnnmodlhs3, O_RDWR) failed: Permission denied (13) in /register.php(202) : eval()'d code on line 1
Solution:(use the correct ownership/permissions)

The first is a dual CPU AMD Opteron 2373EE (4 cores x 2) and I think it did bad because it has some old 250GB SATAs which can only do about 65MB/s max sequential reads. I think it should have blown away the second (AMD X4 640 Quad Core).

Santrex never provided any working server, I believe it was just a dummy management Solus server because the server said it was booted but never connected to the console. I complained to them and eventually the support admitted the server was not working and to wait for 24 hours. I waited for 4-days, after which they sent an e-mail saying my service was being disabled for SPAM ...(when SolusVM shows 0kb of traffic). Th........
These are the only two I've encountered but here is the low-end and note my story is not at all unique.
In my case I was scammed out of money and did not receive any service at all from either company.

Basically you should always be 100% sure that whatever IPyour mail server sends out with has reverse DNS/PTR records. Remember that unless you own your IPs then you won't be able to set your own reverse DNS. Even if you were to create a reverse PTR record on your DNS servers it will be ignored. Reverse DNS is queried to pre-assigned DNS servers of your ISP, so therefore you'll need to contact your ISP/Colo/Hosting provider to do a reverse DNS entry.

This is a great way to use your ftp server space, for example on your web hosting account (althoughI believe many hosts don't allow storage like this), but if you have a VPS/Dedicated Server etc.., this would be perfect. Imagine how easy it is to work with an ftp account that you can just mount as a normal partition or directory in Linux, it would be great for backups etc..

This was unbelievable how much the Xen kernel slows things down, keep in mind both tests were done on the hostnode, one was with the Openvz-Xen hybrid kernel and the other was just OpenVZ. You can see the performance difference is nearly 300% better when not using the Xen kernel.

Just curious.....does China have web hosting?anyone know?I found these:
You might remember my original GluserFS/OpenVZ benchmark which produced a horrible 29.8
This is the exact same system, but using the latest 2.0.8 (with some small files patch which speeds up performance) you can see it is about 25% faster.
I also haven't tuned my config files at all, but there are some settings that should increase performance on small files which I believe i........
This is very disappointing since GlusterFS markets itself as a solution to deploy VPS servers on. On the HNitself I get a Unixbench of about 360.
I'm also using an SSH tunnel to secure the communications, but even before that, things seemed very slow.
